General Information About Hodgkin Lymphoma (HL)

Incidence and Mortality

Estimated new cases and deaths from HL in the United States in 2024:[1]

  • New cases: 8,570.
  • Deaths: 910.

Up to 90% of all newly diagnosed patients with HL can be cured with combination chemotherapy and/or radiation therapy.[2]

Anatomy

Lymphatic system; drawing shows the lymph vessels and lymph organs, including the lymph nodes, tonsils, thymus, spleen, and bone marrow. Also shown is the small intestine (one site of mucosal-associated lymphoid tissue). There are also two pullouts: one showing a close up of the inside structure of a lymph node and the attached artery, vein, and lymph vessels with arrows showing how the lymph (clear, watery fluid) moves into and out of the lymph node, and another showing a close up of bone marrow with blood cells.

The lymph system is part of the body's immune system and is made up of tissues and organs that help protect the body from infection and disease. These include the tonsils, adenoids (not shown), thymus, spleen, bone marrow, lymph vessels, and lymph nodes. Lymph tissue is also found in many other parts of the body, including the small intestine.

HL most frequently presents in lymph node groups above the diaphragm and/or in mediastinal lymph nodes. Involvement of Waldeyer's ring or tonsillar lymph glands is rarely seen.

Risk Factors

Risk factors for HL include the following:

  • Being in early adulthood (aged 20–39 years) (most often) or late adulthood (aged 65 years and older) (less often).
  • Being male.
  • Having a previous infection with the Epstein-Barr virus in the teenage years or early childhood.
  • Having a first-degree relative with HL.

Clinical Features

These and other signs and symptoms may be caused by HL or by other conditions:

  • Painless, swollen lymph nodes in the neck, axilla, or inguinal area.
  • Fever defined as 38ºC or higher.
  • Drenching and recurrent night sweats.
  • Weight loss of 10% or more of baseline weight in the previous 6 months.
  • Pruritus, especially after bathing or after ingesting alcohol.
  • Fatigue.

Treatment of HL should relieve these symptoms within days. For more information, see Hot Flashes and Night Sweats, Pruritus, and Fatigue.

Diagnostic Evaluation

Diagnostic evaluation of patients with lymphoma may include the following:

  1. Biopsy (preferably excisional), with interpretation by a qualified pathologist.
  2. History, with special attention given to the presence and duration of fever, night sweats, and unexplained weight loss of 10% or more of body weight in the previous 6 months.
  3. Physical examination.
  4. Laboratory tests.
    • Complete blood cell count and platelet count.
    • Erythrocyte sedimentation rate.
    • Chemistry panel (electrolytes, blood urea nitrogen, creatinine, calcium, aspartate transaminase, alanine aminotransferase, bilirubin, and alkaline phosphatase) plus lactate dehydrogenase, uric acid, and phosphorus.
  5. Radiographic examination.
    • Computed tomography (CT) of the neck, chest, abdomen, and pelvis; or metabolic imaging (fluorine F 18-fludeoxyglucose positron emission tomography [PET]) with PET-CT. PET-magnetic resonance imaging scans may be equivalent to PET-CT in obtaining staging information at 25% of the radiation dose.[3]
  6. HIV testing.
  7. Hepatitis B and hepatitis C serology.

All stages of HL can be subclassified into A and B categories: B for those with defined general symptoms (described below) and A for those without B symptoms. The B designation is given to patients with any of the following symptoms:

  • Unexplained weight loss (more than 10% of body weight in the 6 months before diagnosis).
  • Unexplained fever with temperatures above 38°C.
  • Drenching and recurrent night sweats.

The most significant B symptoms are fevers and weight loss. Night sweats alone do not confer an adverse prognosis.

Prognostic Factors

The prognosis for a given patient depends on several factors. The most important factors are the following:[1,4,5]

  • Presence or absence of systemic B symptoms.
  • Stage of disease.
  • Presence of large masses.
  • Quality and suitability of the treatment administered.

Other important factors are:[1,4,5]

  • Age.
  • Sex.
  • Erythrocyte sedimentation rate.
  • Hematocrit.
  • Extent of abdominal involvement.
  • Absolute number of nodal sites of involvement.

The best predictor of treatment failure is a PET-CT scan obtained after two cycles of chemotherapy (PET2 scan).[6,7] For limited-stage disease, there are frequent false-positive tests because the relapse risk is low (low-positive predictive value). For advanced-stage disease, up to 15% of patients have a relapse despite a negative PET2 scan (lowering the negative predictive value).[6,7] Combining biomarkers with PET-CT scanning responses or calculating metabolic tumor volume with PET-CT scanning are methods under evaluation to improve prognostic predictions.[6,8,9,10,11]

Follow-Up

Recommendations for posttreatment follow-up are not evidence based, but a variety of opinions have been published for high-risk patients who present with advanced-stage disease and for patients who achieve less-than-complete remission by PET-CT scans at the end of therapy.[12,13,14,15] For patients at high risk of relapse, conventional CT scans are used to avoid increased false-positive test results and increased radiation exposure of serial PET-CT scans.[16]

For patients with negative findings from a PET-CT scan at the end of therapy, routine scans are not advised because of the very low risk of recurrence.[17] Opportunistic scanning is applied when patients present with suspicious symptoms, physical findings, or laboratory test results. The 5-year risk of relapse from diagnosis is 5.6% for patients remaining event-free for 2 years after induction therapy.[18]

Among 6,840 patients enrolled in German Hodgkin Study Group (GHSG) trials, with a median follow-up of 10.3 years, 141 patients had a relapse after 5 years, compared with 466 patients who had a relapse within 5 years. Treatment-related adverse effects and late relapses may occur beyond 20 years of follow-up.[19]

Adverse Long-Term Effects of Therapy

Patients who complete therapy for HL are at risk of developing long-term side effects, ranging from direct damage to organ function or the immune system to second malignancies. For the first 15 years after treatment, HL is the main cause of death. By 15 to 20 years after therapy, the cumulative mortality from a second malignancy, cardiovascular disease, or pulmonary fibrosis exceeds the cumulative mortality from HL.[20,21,22,23] This risk of developing a second malignancy is even higher for individuals with a family history of cancer.[24]

Compared with the general population, long-term survivors of HL have a significantly lower life expectancy.[25] A multicenter cohort study of 4,919 patients treated between 1965 and 2000 and before age 51 years had a median follow-up of 20.2 years. Patients with HL had an absolute excess mortality (AEM) of 123 excess deaths per 10,000 person-years. This risk (standardized mortality ratio, 5.2; 95% confidence interval [CI], 4.2–6.5; AEM, 619) was maintained for 40-year survivors.[25] For example, at age 54 years, the cumulative mortality of 20.0% for HL survivors was commensurate with that of a 71-year-old person from the general population. While mortality from HL dropped precipitously from 1965 to 2000, solid tumor mortality did not change over that time.[25]

Second malignancies

Recommendations for screening for secondary malignancies or follow-up of long-term survivors are consensus based and not derived from randomized trials.[26]

Solid tumors

An increase in second solid tumors has also been observed, especially mesothelioma and cancers of the lung, breast, thyroid, bone/soft tissue, stomach, esophagus, colon and rectum, uterine cervix, and head and neck.[27,28,29,30,31,32,33,34] These tumors occur primarily after radiation therapy or with combined-modality treatment (especially when involving mechlorethamine or procarbazine), and approximately 75% occur within radiation ports. The risk of developing a second solid tumor (cumulative incidence of a second cancer) increases with time after treatment.

  • At 15-years of follow-up, the risk is approximately 13%.[30]
  • At 20-years of follow-up, the risk is approximately 17%.[35]
  • At 25-years of follow-up, the risk is approximately 22%.[27,36]
  • At 40-years of follow-up, the risk is approximately 48%.[37]

In a cohort of 18,862 5-year survivors from 13 population-based registries, the younger patients had elevated risks for breast, colon, and rectal cancers for 10 to 25 years before the ages when routine screening is recommended in the general population.[29] Even with involved-field doses of 15 Gy to 25 Gy, sarcomas, breast cancers, and thyroid cancers occurred with similar incidence in young patients, compared with those receiving higher-dose radiation.[35]

Lung cancer and breast cancer are among the most-common second solid tumors that develop after therapy for HL.

  • Lung cancer. Lung cancer is seen with increased frequency, even after chemotherapy alone, and the risk of this cancer increases with cigarette smoking.[38,39,40,41] In a retrospective Surveillance, Epidemiology, and End Results (SEER) Program analysis, stage-specific survival was decreased by 30% to 60% in HL survivors, compared with patients with de novo non-small cell lung cancer.[42]
  • Breast cancer. Breast cancer is seen with increased frequency after radiation therapy or combined-modality therapy.[27,28,43,44,45] The risk appears greatest for females treated with radiation before age 30 years, especially for girls close to menarche.[46] The incidence of breast cancer increases substantially after 15 years of posttherapy follow-up.[27,47,48]

    In two case-control studies of 479 patients who developed breast cancer after therapy for HL, cumulative absolute risks for developing breast cancer were calculated as a function of radiation therapy dose and the use of chemotherapy.[49,50] With a 30-year to 40-year follow-up, cumulative absolute risks of breast cancer with exposure to radiation range from 8.5% to 39.6%, depending on age at diagnosis. These cohort studies show a continued increase in cumulative excess risk of breast cancer beyond 20 years of follow-up.[49,50]

    In a nested case-control study and subsequent cohort study, patients who received both chemotherapy and radiation therapy had a statistically significant lower risk of developing breast cancer than did those treated with radiation therapy alone.[43,51] Reaching early menopause with fewer than 10 years of intact ovarian function appeared to account for the reduction in risk among patients who received combined-modality therapy.[51] Reduction of radiation volume also decreased the risk of breast cancer after HL.[51]

Late effects of autologous stem cell transplant for failure of induction chemotherapy include second malignancies, hypothyroidism, hypogonadism, herpes zoster, depression, and cardiac disease.[52]

Hematologic cancers

  • Acute myelogenous leukemia (AML). Acute nonlymphocytic leukemia may occur in patients treated with combined-modality therapy or with combination chemotherapy alone, especially with increased exposure to alkylating agents.[30,53]
    • At 10 years after therapy with regimens containing MOPP (mechlorethamine, vincristine, procarbazine, and prednisone), the risk of AML is approximately 3%, with the peak incidence occurring 5 to 9 years after therapy.[30,53] The risk of acute leukemia at 10 years after therapy with ABVD (doxorubicin, bleomycin, vinblastine, and dacarbazine) appears to be less than 1%.[54]
    • A population-based study of more than 35,000 survivors during a 30-year time span identified 217 patients who developed AML. The excess absolute risk (EAR) was significantly higher for older patients (>35 years at diagnosis) than for younger survivors (EAR, 9.9 vs. 4.2 per 10,000 patient-years, P < .001).[55]

Other adverse long-term effects

Treatment of HL also affects the endocrine, cardiac, pulmonary, skeletal, and immune systems. Chronic fatigue can be a debilitating symptom for some long-term survivors.[56] A retrospective survey of 20,007 patients with early- and advanced-stage classical HL treated between 2000 and 2016 (i.e., the era in which ABVD became the preferred frontline chemotherapy regimen) showed 1,321 deaths not attributable to lymphoma (39% of total deaths). Heart disease (estimated EAR as follows: 6.6 per 10,000 patient-years, standardized mortality ratio, 1.7 for early-stage disease and 15.1 per 10,000 patient-years, standardized mortality ratio, 2.1 for advanced-stage disease) and infection (estimated EAR as follows: 3.1 per 10,000 patient-years, standardized mortality ratio, 2.2 for early-stage disease and 10.6 per 10,000 patient-years, standardized mortality ratio, 3.9 for advanced-stage disease) were the leading causes of death, especially in patients older than 60 years.[57]

Infertility. A toxic effect that is primarily related to chemotherapy is infertility, usually after regimens containing MOPP or BEACOPP (bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone).[58,59,60] After six to eight cycles of BEACOPP, most men had testosterone levels within reference range; however, 82% of women younger than 30 years recovered menses (mostly within 12 months), but only 45% of women older than 30 years recovered menses.[61] ABVD appears to spare long-term testicular and ovarian function.[59,62,63] Increasing age and alkylator-based regimens are the two major factors increasing the risk of premature ovarian insufficiency.[61,64,65] A prospective evaluation of gonadal function embedded in the randomized Response-Adapted Therapy in Advanced Hodgkin Lymphoma (RATHL) study for patients with newly diagnosed advanced-stage HL found good recovery of anti-Müllerian hormone concentration and reduction in follicle-stimulating hormone after ABVD or AVD (doxorubicin, vinblastine, dacarbazine), but less recovery after BEACOPP and for women older than 35 years.[64] A PET scan-adapted treatment regimen to reduce the use of BEACOPP also resulted in less infertility and gonadal dysfunction.[66] While cryopreservation of oocytes or sperm remains the first choice for preservation of fertility, luteinizing hormone-releasing hormone agonists can be tried in this setting, although efficacy for patients with HL has not been confirmed as has been confirmed for patients with breast cancer.[67] A national Danish registry of 793 HL survivors showed that patients who did not have a relapse had similar parenthood rates to the general population, but assistive reproduction methods were required more often for HL survivors (male, 21.6% vs. 6.3%; female, 13.6% vs. 5.5%; P ≤ .001 for both comparisons).[68]

Hypothyroidism. Hypothyroidism is a late complication primarily related to radiation therapy.[69,70,71] Long-term survivors who receive radiation therapy to the neck are followed up with annual thyroid-stimulating hormone testing.

Cardiac disease. A late complication primarily related to radiation therapy is cardiac disease, the risk of which may persist for over 30 years after the first treatment.[69,72,73,74,75,76,77,78,79,80] The EAR of fatal cardiovascular disease ranges from 11.9 to 48.9 per 10,000 patient-years and is mostly attributable to fatal myocardial infarction (MI).[72,73,74,76] A retrospective survey of over 6,000 patients with HL treated in trials between 1964 and 2004 found that cardiac exposure to radiation and use of doxorubicin were significant predictors of ischemic heart disease, congestive heart failure, arrhythmias, and vascular disease.[78] In a cohort of 7,033 patients with HL, MI mortality risk persisted for 25 years after first treatment with supradiaphragmatic radiation therapy (dependent on the details of treatment planning), doxorubicin, or vincristine.[76,77] A nested case-control study of 2,617 5-year survivors of HL diagnosed before age 51 years and treated between 1965 and 1995 found that the 25-year risk of moderate to severe heart failure increased for patients receiving anthracyclines. The risk ranged from 11.2% for patients exposed to 0 Gy to 15 Gy radiation up to 32.9% for patients exposed to radiation equal or greater than 21 Gy.[81] The use of subcranial blocking did not reduce the incidence of fatal MI in a retrospective review, perhaps because of the exposure of the proximal coronary arteries to radiation.[73] Compared with a general matched population, HL patients treated with mediastinal radiation were at increased risk of complications, especially during cardiac surgery.[82] Risk prediction models rely on the dose of mediastinal radiation, smoking history, male sex, and anthracycline exposure to define the patients at highest risk.[80] These risk prediction models found that mediastinal radiation therapy combined with doxorubicin exposure conferred the highest risk, followed by mediastinal radiation therapy alone.[80]

In the U.K. RAPID trial, performed between 2003 and 2010, 183 patients with early-stage HL were PET-negative but still received involved-field radiation therapy (IFRT) (20 Gy) after receiving ABVD.[79] The average predicted 30-year cardiovascular mortality was 5.02%, which included 3.52% expected in the general population, 0.94% EAR from the doxorubicin, and 0.56% from the IFRT. Since 2010, radiation therapy techniques have advanced by using smaller target volumes, lower-dose IFRT (20 Gy), deep inspiration breath holding, intensity-modulated radiation therapy, and proton beam therapy.[79] These techniques will need further evaluation to better assess cardiovascular risks from radiation therapy.

Pulmonary impairment. Impairment of pulmonary function may occur as a result of mantle-field radiation therapy; this impairment is not usually clinically evident, and recovery in pulmonary testing often occurs after 2 to 3 years.[83] Pulmonary toxic effects from bleomycin as used in ABVD are seen in patients older than 40 years.[84]

Bone necrosis. Avascular necrosis of bone has been observed in patients treated with chemotherapy and is most likely related to corticosteroid therapy.[85]

Bacterial sepsis. Bacterial sepsis may occur rarely after splenectomy performed during staging laparotomy for HL;[86] it is much more common in children than in adults.

Fatigue. Fatigue is a commonly reported symptom among patients who have completed chemotherapy and radiation therapy. In a case-control study design, most HL survivors reported significant fatigue lasting for more than 6 months after therapy, compared with age-matched controls. Quality-of-life questionnaires given to 5,306 patients on GHSG trials showed that 20% of patients complained of severe fatigue 5 years after therapy, and those patients had significantly increased problems with employment and financial stability.[87,88,89] For more information, see Fatigue.

Neurocognitive impairment. After a median of 23 years from diagnosis, 1,760 HL survivors treated in childhood were compared with 3,180 siblings. Significantly higher rates of memory loss (8.1% vs. 5.7%; P < .05), anxiety (7.0% vs. 5.4%; P < .05), unemployment (9.6% vs. 4.4%; P < .05), depression (9.1% vs. 7.0%; P < .05), and impaired physical quality of life (11.2% vs. 3.0%; P < .05) were reported.[90] Lower risks were associated with survivors who adhered to exercise guidelines and did not smoke, but the design of this study did not allow a cause-and-effect conclusion.

Cellular Classification of HL

Pathologists currently use the World Health Organization (WHO) modification of the Revised European-American Lymphoma (REAL) classification for the histological classification of Hodgkin lymphoma (HL).[1,2]

WHO Modification of the REAL Classification

  • Classic HL.
    • Nodular sclerosis HL.
    • Mixed-cellularity HL.
    • Lymphocyte-depleted HL. Among 10,019 patients who underwent central expert pathology review for the German Hodgkin Study Group, 84 patients (<1%) were identified as having lymphocyte-depleted classic HL.[3] These patients presented more frequently with advanced-stage HL and B symptoms.
    • Lymphocyte-rich classic HL.
  • Nodular lymphocyte–predominant HL (NLPHL). NLPHL is a clinicopathological entity of B-cell origin that is distinct from classic HL.[4,5]

    The typical immunophenotype for classic HL is CD15+, CD20-, CD30+, CD45-, while the profile for lymphocyte-predominant disease is CD15-, CD20+, CD30-, CD45+.

Stage Information for HL

Clinical staging for patients with Hodgkin lymphoma (HL) includes the following:

  • Physical examination and history.
  • Laboratory studies (including sedimentation rate).
  • Thoracic and abdominal/pelvic computerized tomographic (CT) scans with or without positron emission tomography (PET).[1] PET scans combined with CT scans have become the standard imaging for clinical staging.[2]

Staging laparotomy is no longer recommended and should be considered only when the results will allow substantially less treatment. Staging laparotomy should not be done in patients who require chemotherapy. If the laparotomy is required for treatment decisions, the risks of potential morbidity should be considered.[3,4,5,6]

Bone marrow involvement occurs in 5% of patients and is more prevalent in the context of constitutional B symptoms and anemia, leukopenia, or thrombocytopenia. In a retrospective review and meta-analysis of 955 patients in nine studies, fewer than 2% of patients with positive bone marrow biopsy results had only stage I or stage II disease on PET-CT scans.[7] Omission of the bone marrow biopsy for PET-CT–designated early-stage patients did not change treatment selection.[7] In addition, focal skeletal bone lesions on PET-CT predicted bone marrow involvement with a 96.9% (93.0%–99.08%) sensitivity and 99.7% (98.9%–100%) specificity.[7] For these reasons, PET-CT has replaced bone marrow biopsy in the clinical staging of newly diagnosed HL.

Massive mediastinal disease has been defined by the Cotswolds meeting as a thoracic ratio of maximum transverse mass diameter of 33% or more of the internal transverse thoracic diameter measured at the T5/6 intervertebral disc level on chest radiography.[1] Some investigators have designated a lymph node mass measuring 10 cm or more in greatest dimension as massive disease.[8] Other investigators use a measurement of the maximum width of the mediastinal mass divided by the maximum intrathoracic diameter.[9]

Staging Subclassification System

Lugano Classification

The American Joint Committee on Cancer (AJCC) has adopted the Lugano classification to evaluate and stage lymphoma.[10] The Lugano classification system replaces the Ann Arbor classification system, which was adopted in 1971 at the Ann Arbor Conference,[11] with some modifications 18 years later from the Cotswolds meeting.[1]

Table 1. Lugano Classification for Hodgkin and Non-Hodgkin Lymphomaa
Stage Stage Description Illustration
CSF = cerebrospinal fluid; CT = computed tomography; DLBCL = diffuse large B-cell lymphoma; NHL = non-Hodgkin lymphoma.
a Hodgkin and Non-Hodgkin Lymphomas. In: Amin MB, Edge SB, Greene FL, et al., eds.:AJCC Cancer Staging Manual. 8th ed. New York, NY: Springer, 2017, pp. 937–58.
b Stage II bulky may be considered either early or advanced stage based on lymphoma histology and prognostic factors.
c The definition of disease bulk varies according to lymphoma histology. In the Lugano classification, bulk ln Hodgkin lymphoma is defined as a mass greater than one-third of the thoracic diameter on CT of the chest or a mass >10 cm. For NHL, the recommended definitions of bulk vary by lymphoma histology. In follicular lymphoma, 6 cm has been suggested based on the Follicular Lymphoma International Prognostic Index-2 and its validation. In DLBCL, cutoffs ranging from 5 cm to 10 cm have been used, although 10 cm is recommended.
Limited stage
I Involvement of a single lymphatic site (i.e., nodal region, Waldeyer's ring, thymus, or spleen).

Stage I adult lymphoma; drawing shows cancer in one lymph node group and in the spleen. Also shown are the Waldeyer's ring and the thymus. An inset shows a lymph node with a lymph vessel, an artery, and a vein. Cancer cells are shown in the lymph node.

IE Single extralymphatic site in the absence of nodal involvement (rare in Hodgkin lymphoma).  
II Involvement of two or more lymph node regions on the same side of the diaphragm.

Stage II adult lymphoma; drawing shows cancer in two lymph node groups above the diaphragm and below the diaphragm. An inset shows a lymph node with a lymph vessel, an artery, and a vein. Cancer cells are shown in the lymph node.

IIE Contiguous extralymphatic extension from a nodal site with or without involvement of other lymph node regions on the same side of the diaphragm.

Stage IIE adult lymphoma; drawing shows cancer that has spread from a group of lymph nodes to a nearby area. Also shown is a lung and the diaphragm. An inset shows a lymph node with a lymph vessel, an artery, and a vein. Cancer cells are shown in the lymph node.

II bulkyb Stage II with disease bulk.c  
Advanced stage
III Involvement of lymph node regions on both sides of the diaphragm; nodes above the diaphragm with spleen involvement.

Stage III adult lymphoma; drawing shows the right and left sides of the body. The right side of the body shows cancer in a group of lymph nodes above the diaphragm and below the diaphragm. The left side of the body shows cancer in a group of lymph nodes above the diaphragm and cancer in the spleen.

IV Diffuse or disseminated involvement of one or more extralymphatic organs, with or without associated lymph node involvement; or noncontiguous extralymphatic organ involvement in conjunction with nodal stage II disease; or any extralymphatic organ involvement in nodal stage III disease. Stage IV includes any involvement of the CSF, bone marrow, liver, or multiple lung lesions (other than by direct extension in stage IIE disease).

Stage IV adult lymphoma; drawing shows four panels: (a) the top left panel shows cancer in the liver; (b) the top right panel shows cancer in the left lung and in two groups of lymph nodes below the diaphragm; (c) the bottom left panel shows cancer in the left lung and in a group of lymph nodes above the diaphragm and below the diaphragm; and (d) the bottom right panel shows cancer in both lungs, the liver, and the bone marrow (pullout). Also shown is primary cancer in the lymph nodes and a pullout of the brain with cerebrospinal fluid (in blue).

Note: Hodgkin lymphoma uses A or B designation with stage group. A/B is no longer used in NHL.

The E designation is used when well-localized extranodal lymphoid malignancies arise in or extend to tissues beyond, but near, the major lymphatic aggregates. Stage IV refers to disease that is diffusely spread throughout an extranodal site, such as the liver. If pathological proof of involvement of one or more extralymphatic sites has been documented, the symbol for the site of involvement, followed by a plus sign (+), is listed.

N = nodes H = liver L = lung M = bone marrow
S = spleen P = pleura O = bone D = skin

Prognostic Groups

Many investigators and many new clinical trials employ a clinical staging system that divides patients into three major groups that are also useful for the clinician:[12]

  • Early favorable.
  • Early unfavorable.
  • Advanced.

The group assignment depends on:

Whether the patient has early or advanced disease.
The type and number of adverse prognostic factors present.

Early-stage adverse prognostic factors:

  • Large mediastinal mass (>33% of the thoracic width on chest x-ray, ≥10 cm on CT scan).
  • Extranodal involvement.
  • Elevated erythrocyte sedimentation rate (>30 mm/h for B stage [symptoms], >50 mm/h for A stage [symptoms]).
  • Involvement of three or more lymph node areas.
  • Presence of B symptoms.

Early favorable group: Clinical stage I or II without any of the adverse prognostic factors listed above.

Early unfavorable group: Clinical stage I or II with one or more of the adverse prognostic factors listed above.

Advanced-stage adverse prognostic factors:

For patients with advanced-stage HL, the International Prognostic Factors Project on Advanced Hodgkin's Disease developed the International Prognostic Index with a score that is based on the following seven adverse prognostic factors:[13]

  • Albumin level lower than 40 g/L.
  • Hemoglobin level lower than 105 g/L.
  • Male sex.
  • Age 45 years or older.
  • Stage IV disease.
  • White blood cell (WBC) count of 15 × 109 /L or higher.
  • Absolute lymphocytic count lower than 0.6 × 109 /L or lymphocyte count higher than 8% of the total WBC count.

Advanced group: Clinical stage III or IV with up to three of the adverse risk factors listed above. Patients with advanced disease have a 60% to 80% rate of freedom from progression of disease at 5 years from treatment with first-line chemotherapy.[13][Level of evidence C2] An updated clinical prediction model uses continuous variables listed for the International Prognostic Index above, with an online calculator available.[14]

Treatment Option Overview for HL

After initial clinical staging for Hodgkin lymphoma (HL), patients with early favorable disease or early unfavorable disease are treated with ABVD (doxorubicin, bleomycin, vinblastine, and dacarbazine) chemotherapy with or without involved-field or nodal radiation.

Patients with advanced-stage disease are primarily treated with chemotherapy alone, although subsequent radiation therapy may be applied for initial bulky disease (≥10 cm mediastinal mass) or for residual adenopathy (>2.5 cm) with positive findings after a postchemotherapy positron emission tomography (PET) scan.[1] Treatment regimen preferences and application, as well as relative risks, differ regionally.

Patients with HL who are older than 60 years may have more treatment-related morbidity and mortality; maintaining the dose intensity of standard chemotherapy may be difficult.[2,3] Other therapies have been proposed for older patients with lower tolerance for conventional regimens, but no randomized trials have been conducted with these regimens.[4] Twenty-seven previously untreated patients older than 60 years, judged by the investigator to be in poor condition and unable to undergo chemotherapy, received brentuximab vedotin. A 92% overall response rate and 73% complete remission rate were reported.[5][Level of evidence C3] Brentuximab vedotin has been combined with dacarbazine [6] or sequentially with AVD (doxorubicin, vinblastine, dacarbazine) [7], reporting acceptable toxicities in an older population. A retrospective review of 287 patients aged 60 years or older with early-stage favorable HL in two German Hodgkin Study Group (GHSG) trials (HD10 and HD13) showed increased bleomycin-induced lung toxicity with more than two cycles of exposure to bleomycin.[8]

Radiation Therapy

Radiation therapy alone is almost never used to treat patients newly diagnosed with early favorable classic HL.[9] In HL, the appropriate dose of radiation alone is 20 Gy to 30 Gy to clinically uninvolved sites and 30 Gy to 36 Gy to regions of initial nodal involvement.[9,10,11] When mediastinal radiation will encompass the left side of the heart or will increase breast cancer risk in young female patients, proton therapy may be considered to reduce the radiation dose to organs at risk.[12] When used as a single modality, radiation therapy is delivered to the neck, chest, and axilla (mantle field) and then to an abdominal field to treat para-aortic nodes and the spleen (splenic pedicle). In some patients, pelvic nodes are treated with a third field. The three fields constitute total nodal radiation therapy. In some cases, the pelvic and para-aortic nodes are treated in a single field called an inverted Y.[9,10,11]

Treatment of Early Favorable Classic HL

Patients are designated as having early favorable classic Hodgkin lymphoma (HL) when they have clinical stage I or stage II disease and none of the following adverse prognostic factors:

  • B symptoms (unexplained fever ≥38°C, soaking night sweats, unexplained weight loss ≥10% within 6 months).
  • Extranodal disease.
  • Bulky disease (≥10 cm or >33% of the chest diameter on chest x-ray).
  • Three or more sites of nodal involvement.
  • Sedimentation rate of 50 mm/h or higher.

Treatment Options for Early Favorable Classic HL

Treatment options for early favorable classic HL include the following:

  1. Chemotherapy with or without radiation therapy.

Chemotherapy with or without radiation therapy

Treatment options include the following:

  • ABVD (doxorubicin, bleomycin, vinblastine, and dacarbazine) for three to six cycles.[1]
  • ABVD for two to four cycles plus involved-field radiation therapy (IFRT) (20 Gy or 30 Gy).
  • Radiation therapy alone in certain circumstances (such as for older adults with absolute contraindications for using chemotherapy).[2,3]

Historically, radiation therapy alone was the primary treatment for patients with early favorable classic HL, often after confirmatory negative staging laparotomy.

The late mortality from solid tumors (especially in the lung, breast, gastrointestinal tract, and connective tissue) and cardiovascular disease makes radiation therapy a less-attractive option for the best-risk patients, who have the highest probability of cure and long-term survival.[4,5,6,7,8] Clinical trials have focused on regimens with chemotherapy and IFRT or with chemotherapy alone.[1]

Evidence (chemotherapy and/or radiation therapy):

For patients with early favorable classic HL, the following four trials established ABVD alone for four cycles or ABVD for two cycles plus 20 Gy of IFRT.

  1. A randomized, prospective trial from the National Cancer Institute of Canada involving 123 patients with early favorable classic HL compared ABVD for four to six cycles with subtotal nodal radiation.[9][Level of evidence A1]
    • With a median follow-up of 11.3 years, no difference was observed in event-free survival rates (89% vs. 86%; P = .64) or in overall survival rates (OS) (98% vs. 98%; P = .95).
  2. A randomized study from the Milan Cancer Institute of patients with clinical early-stage HL compared 4 months of ABVD followed by IFRT with 4 months of ABVD followed by extended-field radiation therapy (EFRT).[10][Level of evidence B1]
    • The results showed similar OS and freedom from progression of disease with a 10-year median follow-up, but the study had inadequate statistical power to determine noninferiority of IFRT versus EFRT.
  3. In the HD10 trial, the German Hodgkin Study Group (GHSG) randomly assigned 1,190 patients with early favorable HL to receive one of the following:[11,12][Level of evidence A1]
    • Two cycles of ABVD plus 30 Gy of IFRT.
    • Two cycles of ABVD plus 20 Gy of IFRT.
    • Four cycles of ABVD plus 30 Gy of IFRT.
    • Four cycles of ABVD plus 20 Gy of IFRT.

    The following results were observed for the trial:

    • With an 8.2-year median follow-up, no differences were observed (hazard ratio [HR], 1.0; 95% confidence interval [CI], 0.6–1.5) in 10-year progression-free survival (PFS) rates (87%) or OS rates (94%) for all four groups.
  4. A follow-up study by the GHSG (HD13 trial) compared modified versions of ABVD with elimination of dacarbazine, bleomycin, or both in combination with 30 Gy of radiation therapy in 1,502 patients with early favorable HL.[13]
    • After 5 years, freedom from treatment failure was significantly worse when dacarbazine, bleomycin, or both were omitted.
    • This trial suggests that ABVD remains the standard chemotherapy regimen.

Other trials have investigated the role of positron emission tomography (PET) scans for early favorable HL.

  1. Three prospective randomized trials (EORTC/LYSA/FIL H10 [NCT00433433][14,15]; RAPID [NCT00943423][16,17]; and GHSG HD16 [NCT00736320][18]) of 2,889 patients with early-stage disease investigated the use of PET‒computed tomography (CT) scans to modify therapy.[14,15,16,17,18]
    • Among patients with early favorable HL who had negative PET-CT scan results (Deauville score of 1 or 2) after two or three cycles of ABVD, radiation therapy could be omitted with no significant loss of OS in all three trials.[14,16,18][Level of evidence B1]

      However, two of the trials showed an increased risk of relapse when radiation therapy was omitted. In the GHSG HD16 trial, for the 628 patients with PET2-negative disease (PET after two cycles of ABVD), the 5-year PFS rate was 93.4% (95% CI, 90.4%–96.5%) with combined modality therapy and 86.1% (95% CI, 81.4%–90.0%) with ABVD alone (HR, 1.78; 95% CI, 1.02–3.12).[18] A subsequent analysis of the GHSG HD16 trial showed that most of the recurrences occurred in the proposed radiation field.[15] In the EORTC/LYSA/FIL H10 trial, the 10-year PFS rate was 98.8% with three cycles of ABVD plus radiation therapy and 85.4% with four cycles of ABVD without radiation therapy (HR, 13.2; 95% CI, 3.1–55.8; P < .001).[17]

      In summary, this 7% to 13% difference in PFS without a difference in OS can be seen either as a mandate to combine radiation therapy with ABVD to avoid recurrences or as a rationale to give four or more cycles of AVBD when omitting radiation therapy.

    • ABVD was given for three cycles (six doses) in the RAPID study,[16] for four cycles (eight doses) in the EORTC/LYSA/FIL H10 study,[14] and for two cycles (four doses) in the GHSG HD16 study [18] when applied without radiation therapy.
    • None of the studies randomly assigned therapy for positive results from an interim PET-CT scan (Deauville score of 3, 4, or 5) after two or three cycles of ABVD because this occurred in only 15% to 25% of the patients studied. One of the studies (RAPID) added an extra cycle of ABVD and IFRT to 30 Gy,[16] another study (EORTC H10F) switched to BEACOPP (bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone)–escalated therapy for two cycles plus involved nodal radiation therapy to 30 Gy,[14] and the other study (GHSG HD16) added IFRT to 30 Gy.[18]

      In the RAPID study (NCT00943423), patients with postchemotherapy PET-CT Deauville scores of 5 (uptake ≥3 times maximum liver uptake) had inferior 5-year PFS rates (61.9%; 95% CI, 41.1%–82.7%) and 5-year OS rates (85.2%; 95% CI, 69.7%–100%) (P = .002) when compared with patients with Deauville scores of 1 to 4 (P < .001).[19]

Older patients with early favorable HL have also been studied.

  1. In 287 patients older than 60 years or with early favorable disease, a retrospective review of pulmonary toxicity in the HD10 and HD13 trials showed the following:[20]
    • Two cycles of ABVD plus IFRT (137 patients): 2% pulmonary toxicity.
    • Two cycles of AVD (omitting bleomycin) plus IFRT (82 patients): 2% pulmonary toxicity.
    • Four cycles of ABVD plus IFRT (68 patients): 10% pulmonary toxicity.

For older patients (>60 years) with early favorable disease, when more than two cycles of ABVD are required, bleomycin may be omitted to avoid pulmonary toxicity.

Summary of early favorable classic HL:

  • ABVD alone for three to four cycles is recommended for patients with early favorable classical HL when the interim PET-CT scan results are negative after two or three cycles of chemotherapy.[21] These patients are also unlikely to ever have a relapse, so routine CT scans are not recommended in follow-up.
  • With positive interim PET-CT scan results, extra cycles of ABVD and involved nodal radiation therapy are recommended.
  • A combined-modality approach with two cycles of ABVD and 20 Gy of IFRT can also be used for patients with early favorable classic HL.[21] In this situation, a PET-CT scan to assess response after completion of therapy would suffice.

Treatment of Early Unfavorable Classic HL

Patients are designated as having early unfavorable classic Hodgkin lymphoma (HL) when they have clinical stage I or stage II disease and one or more of the following risk factors:

  • B symptoms (unexplained fever ≥38°C, soaking night sweats, unexplained weight loss ≥10% within 6 months).
  • Extranodal disease.
  • Bulky disease (≥10 cm or >33% of the chest diameter on chest x-ray).
  • Three or more sites of nodal involvement.
  • Sedimentation rate of 50 mm/h or higher.

A retrospective review found that infradiaphragmatic early-stage disease appears to have an inferior outcome compared with the more frequent (>90%) supradiaphragmatic disease, with a decrement in overall survival (OS) rates of 6% (91.5% vs. 97.6%; P < .001).[1][Level of evidence C2]

Treatment Options for Early Unfavorable Classic HL

Treatment options for early unfavorable classic HL include the following:

  1. Chemotherapy with or without radiation therapy.

Chemotherapy with or without radiation therapy

Treatment options include the following:[2,3]

  • Four cycles of ABVD (doxorubicin, bleomycin, vinblastine, and dacarbazine) plus involved-field radiation therapy (IFRT) (20 Gy–30 Gy).[4,5,6,7]
  • Six cycles of ABVD.[2,3]

See Table 4 for a description of the chemotherapy regimens used to treat HL.

Evidence (chemotherapy and radiation therapy):

  1. A randomized, prospective trial from the National Cancer Institute of Canada (NCIC) involving 276 patients with early unfavorable HL compared ABVD for four to six cycles with ABVD for two cycles plus extended-field radiation therapy (EFRT).[2][Level of evidence A1]
    • With a median follow-up of 11.3 years, the freedom from progression score favored combined-modality therapy (86% vs. 94%; P = .006), but the OS rate was better for ABVD alone (92% vs. 81%; P = .04).
    • The trend toward a worse survival for the combined-modality arm was attributed to excess secondary malignancies and cardiovascular deaths. In this trial, the EFRT used higher doses and significantly larger exposure to body sites than are employed in current practice.
    • This trial established that six cycles of ABVD can be used alone and that long-term complications from radiation therapy can negate differences for progression-free survival (PFS).
  2. In the HD11 trial, the German Hodgkin Study Group (GHSG) randomly assigned 1,395 patients with early unfavorable HL to receive one of the following:
    • Four cycles of ABVD plus 30 Gy of IFRT.
    • Four cycles of ABVD plus 20 Gy of IFRT.
    • Four cycles of BEACOPP (bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone) plus 30 Gy of IFRT.
    • Four cycles of BEACOPP plus 20 Gy of IFRT.

    The following results were observed:

    • With an 8.8-year median follow-up, no differences were observed in OS rates (93%–96%) for all four groups.[8][Level of evidence A1]
    • In the study arms using 30 Gy of IFRT, there was no difference in freedom from treatment failure between BEACOPP and ABVD (P = .65), but a significant difference against ABVD was seen for PFS when 20 Gy of IFRT was used (10-year PFS rate, 84% vs. 76%; hazard ratio (HR), 1.5; 95% confidence interval [CI], 1.0–2.1).[5][Level of evidence B1]
    • In this trial, four cycles of ABVD plus 30 Gy of IFRT established this regimen as the preferred approach (or BEACOPP with 20 Gy of IFRT).
  3. In the HD14 trial, the GHSG randomly assigned 1,528 patients with early unfavorable HL to receive either four cycles of ABVD plus 30 Gy of IFRT or two cycles of escalated BEACOPP followed by two cycles of ABVD plus 30 Gy of IFRT.[6][Level of evidence A1]
    • With a median follow-up of 43 months, no difference was observed in OS.
    • In this trial, four cycles of ABVD plus 30 Gy of IFRT established this regimen as the preferred approach.
  4. In the H9-U trial, the European Organisation for Research and Treatment of Cancer–Groupe d'Étude des Lymphomes de l'Adulte (EORTC/GELA) randomly assigned 808 patients with early unfavorable disease (including 40% with bulky disease) to receive one of the following [7][Level of evidence A1]:
    • Six cycles of ABVD plus 36 Gy of IFRT.
    • Four cycles of ABVD plus 36 Gy of IFRT.
    • Four cycles of BEACOPP plus 36 Gy of IFRT.

    The following results were observed:

    • With a median follow-up of 64 months, no differences were observed (event-free survival rates, 89%–92%; P = .38; or OS rates, 91%–96%; P = .89).
    • Based on toxicities, four cycles of ABVD plus IFRT was established as the preferred regimen.
  5. A multicenter nonrandomized study in 117 patients (most of whom had bulky disease) showed that four cycles of BV-AVD (brentuximab vedotin + doxorubicin, vinblastine, and dacarbazine) with or without involved-site radiation therapy is well-tolerated and effective.[9]
    • With a median follow-up of 3.8 years, the overall 2-year PFS was 94% (95% CI, 89.7%–98.3%). The 2-year OS was 99.1% (97.3%– 100.0%).[9][Level of evidence C2]
    • This pilot study requires confirmation, but the results may be reassuring when using the regimen for patients who cannot take bleomycin or need to limit anthracycline exposure.

Could the radiation therapy be omitted to minimize late morbidity and mortality from secondary solid tumors and from cardiovascular disease?[3]

The NCIC study addressed this question in patients with early unfavorable HL. Although four to six cycles of ABVD alone had improved OS compared with a combined-modality approach, the use of EFRT in the combined-modality arm is excessive by current standards, and late effects will be magnified with these larger fields.[2] In addition, chemotherapy alone was 8% worse in freedom from disease progression compared with the combined-modality approach. An indirect comparison for using ABVD alone is that the 94% OS rate reported for patients with early unfavorable HL in the NCIC study [2] at 11 years is equivalent to the survival reported at 11 years in the GHSG's HD6 (NCT00002561), HD10 (NCT01399931), and HD11 (NCT0264953) trials using combined-modality therapy.[10] In addition, for the HD6 and HD10 trials, between the reports at 55 months and subsequently at 133 months, cardiovascular events doubled and solid tumor events tripled.[10]
A retrospective analysis of 215 patients treated with ABVD and more contemporary radiation therapy (20 Gy–30 Gy, limited field) was compared with a cohort of 860 individuals matched for age, sex, geographical region, and major medical diseases.[11] Excess morbidity was still seen in terms of second malignancies, cardiovascular disease, and respiratory disease (HR, 1.5–7.6), but at a lower rate than in reports using regimens and doses from earlier decades.[11]

A Cochrane meta-analysis of 1,245 patients in five randomized clinical trials suggested improved survival for combined-modality therapy versus chemotherapy alone (HR, 0.40; 95% CI, 0.27–0.61).[12] However, the five randomized trials that were analyzed had inadequate follow-up to account for the late toxicities and increased mortality seen with radiation therapy after 10 years.

Other trials have investigated the role of positron emission tomography‒computed tomography (PET-CT) scans for patients with early unfavorable HL.

  1. A randomized prospective trial (EORTC HIOU) of 1,196 patients with early unfavorable HL investigated the use of PET-CT scans to modify therapy after two cycles of therapy.[13]
    1. Among the 815 patients with negative PET-CT findings (Deauville score of 1 or 2) after two cycles of ABVD, the patients randomly assigned to receive six cycles of ABVD had inferior PFS rates compared with patients who received four cycles of ABVD plus involved nodal radiation therapy (94.7% vs. 99.2%; P = .026), but no difference in OS.[Level of evidence B1]
    2. The use of ABVD for six cycles is acceptable in the absence of radiation therapy for patients with early unfavorable classic HL who have negative PET-CT results after two cycles of ABVD, if one can accept a 5% rate of increased relapse, with no decrement in OS after salvage therapy.
    3. In a follow-up report from this trial, 381 patients with positive PET-CT results (Deauville score of 3, 4, or 5) after two cycles of ABVD were randomly assigned to receive four cycles of ABVD plus 30 Gy of involved nodal radiation therapy versus two cycles of ABVD followed by two cycles of escalated BEACOPP plus 30 Gy of involved nodal radiation therapy.[14][Level of evidence A1]
      • The 5-year PFS rate was 91% in the BEACOPP arm compared with 77% in the ABVD arm (P = .002).
      • The 5-year OS rate was 96% in the BEACOPP arm compared with 89% in the ABVD arm (P = .02).

    This trial supports adding escalated BEACOPP to ABVD for patients with early unfavorable classic HL who have positive PET-CT results after two cycles.

  2. A randomized prospective trial (GHSG HD17 [NCT01356680]) of 1,100 patients with early-stage unfavorable HL evaluated whether radiation therapy can be omitted in patients with a complete metabolic response (CMR) on PET-CT scan after two cycles of escalated BEACOPP and two cycles of regular-dose BEACOPP (2 + 2 regimen). Patients were randomly assigned to receive combined-modality therapy (n = 548) or PET4-guided therapy (n = 552). Combined-modality therapy included both the 2 + 2 regimen and involved-field radiation therapy. PET4-guided therapy included the 2 + 2 regimen for all patients and involved-node radiation therapy for the patients with a positive PET4 scan (n = 160). A total of 333 patients in the PET4-guided therapy group were PET4-negative and received chemotherapy alone.[15]
    • With a median follow-up of 46.2 months, the 5-year PFS rate was 97.3% (95% CI, 94.5%–98.7%) for patients who received combined-modality therapy and 95.1% (95% CI, 92.0%–97.0%) for patients who received PET4-guided therapy (HR, 0.523; 95% CI, 0.23–1.21). The between-group difference was 2.2% (95% CI, -0.9% to 5.3%) and excluded the noninferiority margin of 8%.[15][Level of evidence B1]
    • In the subgroup of PET4-negative patients who received chemotherapy alone, the difference in 5-year PFS was 1.7% (95% CI, -1.8% to 5.3%).
    • Omitting radiation therapy for patients in CMR after four cycles of BEACOPP-based chemotherapy did not significantly impair PFS.
  3. A prospective phase II trial included 94 patients with early-stage (I/II) bulky disease (defined as mass >10 cm or >⅓ maximum intrathoracic diameter on chest x-ray). Patients received ABVD for two cycles, followed by interim PET (PET2) scan. PET-negative patients (78% of the total) were defined as Deauville 1, 2, or 3 and received two more cycles of ABVD. PET2-positive patients (Deauville 4 or 5, 22% of the total) received four cycles of escalated BEACOPP, followed by 30.6 Gy of IFRT.[16]
    • With a median follow-up of 60 months, the 3-year PFS rate was 93.1% in PET2-negative patients and 89.7% in PET2-positive patients. The 3-year OS rate was 98.6% in PET2-negative patients and 94.4% in PET2-positive patients.[16][Level of evidence C3]

To summarize:

  • Most of the trials support using four cycles of ABVD plus 30 Gy of IFRT or involved nodal radiation therapy.[17]
  • ABVD alone for six cycles is a reasonable alternative despite a 5% to 6% decrement in PFS because the long-term toxicities of adding radiation therapy will affect OS, which is the most important patient outcome.[17]
  • For patients with a positive PET-CT (usually Deauville 4 or 5) after two cycles of ABVD, adding brentuximab vedotin while eliminating bleomycin can be considered. BEACOPP or clinical trials investigating the addition of brentuximab vedotin or checkpoint inhibitors in this setting would be indicated.
  • Radiation therapy may be omitted in patients with a negative PET-CT (Deauville 1) after two to four cycles of chemotherapy.

Patients with bulky disease (≥10 cm) or massive mediastinal involvement were excluded from most of the trials. On the basis of historical comparisons to chemotherapy or radiation therapy alone, these patients receive combined-modality therapy.[18,19,20][Level of evidence C2] A retrospective review published in a preliminary abstract reported on 194 patients with bulky disease who had PET-CT scans at the completion of chemotherapy; 112 of them had negative PET results (Deauville score of 1 or 2).[21] The observed 86% OS rate at 5 years suggests that radiation therapy can be excluded for patients with massive mediastinal disease who have negative PET-CT scan results after six cycles of therapy.[21][Level of evidence C2]

Treatment of Advanced Classic HL

The following adverse prognostic factors for advanced classic Hodgkin lymphoma (HL) have been combined into the International Prognostic Score for advanced-stage HL:[1]

  • Albumin level lower than 40 g/L.
  • Hemoglobin level lower than 105 g/L.
  • Male sex.
  • Age 45 years or older.
  • Stage IV disease.
  • White blood cell (WBC) count of 15 × 109 /L or higher.
  • Absolute lymphocyte count lower than 0.6 × 109 /L or a lymphocyte count higher than 8% of the total WBC count.
Table 5. Risk Factors and Survival Rates for Patients With Advanced Classic Hodgkin Lymphoma
No. of Risk Factors 5-Year FFP (%) 5-Year OS (%)
FFP = freedom from progression; No. = number; OS = overall survival.
0 88 98
1 84 97
2 80 92
3 74 91
4 67 88
≥5 62 73

Even the highest-risk patients in this index have a 5-year freedom from progression rate above 60% and a 5-year overall survival (OS) rate above 70%.[1]

Treatment Options for Advanced Classic HL

Treatment options for advanced classic HL include the following:

  1. Chemotherapy.

Chemotherapy

The chemotherapy regimen BV-AVD (brentuximab vedotin [an antibody-drug conjugate directed against CD30] + doxorubicin, vinblastine, and dacarbazine) is administered for six cycles. This replaces ABVD (doxorubicin, bleomycin, vinblastine, and dacarbazine), the previous standard regimen for three decades.[2,3] The ABVD regimen remains a viable option in cost-conscious settings.

See Table 4 for a description of the chemotherapy regimens used to treat HL.

Evidence (chemotherapy):

  1. A randomized prospective trial (NCT01712490) included 1,334 patients with previously untreated advanced-stage HL. The study compared ABVD with BV-AVD (a regimen substituting brentuximab vedotin for bleomycin).[4]
    • With a median follow-up of 73 months, the 6-year OS rate was 93.9% for patients who received BV-AVD (95% confidence interval [CI], 91.6%–95.5%) and 89.4% for patients who received ABVD (95% CI, 86.6%–91.7%) (hazard ratio [HR], 0.59; 95% CI, 0.40–0.88; P = .009).[4]
    • With a median follow-up of 73 months, the 6-year progression-free survival (PFS) rate was 82.3% for patients who received BV-AVD (95% CI, 79.1%–85.0%) and 74.5% for patients who received ABVD (95% CI, 70.8%–77.7%) (HR, 0.68; 95% CI, 0.53–0.86; P = .002).[4]
    • Among patients who received BV-AVD, there was significantly more grade 3 or 4 peripheral neuropathy (67% vs. 43%); however, there was more than 80% partial or complete recovery, with a median time-to-resolution of 16 weeks for BV-AVD and 10 weeks for ABVD. Pulmonary toxicity led to 11 deaths in the ABVD arm.
    • Although fertility was not directly assessed, pregnancies and live births subsequently occurred in both arms of the trial for female patients and female partners of the male patients.
    • BV-AVD can cost 50 times more than ABVD (in 2018).[5]
    • BV-AVD is a new standard of care for patients with advanced-stage classic HL.
  2. An ongoing, randomized, prospective trial (NCT03907488), published in abstract form, enrolled 976 patients with previously untreated advanced-stage HL. The study compared the new standard therapy BV-AVD with N-AVD, a regimen substituting nivolumab for brentuximab vedotin.[6]
    • With a median follow-up of 12.1 months, the 1-year PFS rate favored N-AVD over BV-AVD at 94% (95% CI, 91%–96%) versus 86% (95% CI, 82%–90%) (HR, 0.48; 95% CI, 0.27–0.87; P = .001).[6]
    • Treatment discontinuation due to side effects was twice as likely for patients who received BV-AVD (22% vs. 11%), mainly because of peripheral sensory neuropathy.
    • Longer follow-up to assure continued improvement in PFS, and ultimately OS benefit, and a full publication will be required before establishing N-AVD as a new standard of care.
    • A preplanned analysis, published in abstract form, included 97 patients aged 60 years or older. With a median follow-up of 12.1 months, the 1-year PFS favored N-AVD over BV-AVD at 93% versus 64% (HR, 0.35; 95% CI, 0.12–1.02; P = .022).[7] The BV-AVD regimen had substantially worse side effects including septicemia, peripheral sensory neuropathy, nausea, diarrhea, anorexia, and weight loss, compared with rash and hypothyroidism for N-AVD.[7]
    • Based on these preliminary results, some clinicians are requesting insurance coverage for N-AVD for newly diagnosed patients with advanced-stage HL who have contraindications to brentuximab vedotin (such as prior neurological problems), or are aged 60 years or older.
  3. In multiple prospective trials and a meta-analysis, ABVD therapy for 6 to 8 months for patients with newly diagnosed advanced HL, showed equivalent OS when compared with other regimens (i.e., BEACOPP [bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone], escalated BEACOPP, Stanford V [doxorubicin, vinblastine, mechlorethamine, etoposide, vincristine, bleomycin, and prednisone], and MOPP-ABV [mechlorethamine, vincristine, procarbazine prednisone/doxorubicin, bleomycin, and vinblastine]).[8,9,10,11,12,13,14,15][Level of evidence A1]

Multiple studies have addressed the role of radiation therapy consolidation after induction chemotherapy for advanced-stage HL.

  1. Three prospective randomized trials did not show a benefit in OS from the addition of consolidative radiation therapy to chemotherapy for patients with advanced-stage disease.[16,17,18][Level of evidence A1]
  2. In a meta-analysis of 1,740 patients treated in 14 different trials, no improvement was observed in 10-year OS for patients with advanced-stage HL who received combined-modality therapy compared with chemotherapy alone.[19][Level of evidence C1]
  3. No survival advantage is known for the use of radiation consolidation for patients with massive mediastinal disease and advanced-stage disease.[20]

    A randomized prospective trial with a median follow-up of 5.9 years included 320 patients with advanced-stage HL and a large nodal mass (≥5 cm). Patients were randomly assigned to receive radiation therapy or no further treatment after six cycles of ABVD. For patients with a complete metabolic response on positron emission tomography (PET)–computed tomography (CT) after six cycles of ABVD, there was no difference in the 6-year PFS rate for patients who received radiation therapy (91%; 95% CI, 84%–99%) versus patients who received no further treatment (95%; 95% CI, 89%–100%, P = .62).[21][Level of evidence B1]

  4. The German Hodgkin Lymphoma Study Group HD15 trial showed that a negative PET scan after induction therapy with BEACOPP (escalated or every 14 days) for advanced-stage HL was highly predictive for a good outcome, even with the omission of consolidative radiation therapy (negative predictive value for PET was 94% [95% CI, 91%–97%]).[22] In the German Hodgkin Study Group HD18 trial (NCT00515554), PET scan negativity after two cycles (PET2) of escalated BEACOPP allowed reduction to four cycles of therapy instead of six or eight cycles because of the equivalent 5-year PFS (90.8% vs. 92.2%; difference 1.4%; 95% CI, -2.7–5.4).[23][Level of evidence B1] The HD18 trial established a Deauville score of 4 or 5 as PET2 positive based on a 3-year OS.[24]

Other trials have investigated the role of PET scans in patients with advanced classic HL.

  1. A randomized prospective trial of 1,214 patients with advanced-stage HL (RATHL [NCT00678327]) investigated the use of PET-CT scans after two cycles of ABVD to modify therapy.[25,26] Patients with negative findings from a PET-CT scan (Deauville score of 1, 2, or 3) were randomly assigned to receive four more cycles of ABVD versus four cycles of AVD (doxorubicin, vinblastine, and dacarbazine).
    1. With a median follow-up of 7.3 years for the 937 patients with negative PET-CT results, there was no difference in the 7-year OS rate (93.2%; 95% CI, 90.2%–95.3% for ABVD vs. 93.5%; 95% CI, 90.5%–95.5% for AVD).[26][Level of evidence A1]
    2. The absolute difference in the 3-year PFS rate (ABVD minus AVD) was 1.3% (95% CI, -3.0% to 4.7%), which falls within the predefined noninferiority margin. This means that there was no PFS advantage for continuing bleomycin for PET-negative patients on the interim scan.
    3. However, pulmonary toxicity was worse in the continued ABVD arm, with significantly more grade 3 or 4 respiratory events and worsened long-term diffusing capacity of the lung for carbon monoxide levels persisting beyond 1 year.
    4. This study concluded that bleomycin may be omitted after the second cycle of ABVD if findings from the PET-CT scan are negative (Deauville score of 1, 2, or 3).
    5. The patients with positive PET-CT scan results (Deauville score of 4 or 5) after two cycles of ABVD received BEACOPP.
      • With a median follow-up of 41 months for the 172 patients with positive PET-CT results, the 3-year PFS rate was 67.5% and the OS rate was 87.8%
      • This trial did not establish that switching to BEACOPP was superior to remaining on ABVD.
  2. In a nonrandomized trial (SWOG S0816 [NCT00822120]), 336 patients with advanced HL received two cycles of ABVD and then were evaluated by PET scan.[27] PET2–negative patients (Deauville score of 1 to 3) completed four more cycles of ABVD, while the 60 PET2–positive patients (18% of total) were switched to escalated BEACOPP.
    • With a median follow-up of 5.9 years, the 5-year PFS rate for the PET2–positive patients was 66% (95% CI, 52%–76%).[27][Level of evidence C3]

Older patients with advanced-stage HL have also been studied.

  1. In a multicenter phase II study, 48 patients older than 60 years, of whom 81% had advanced-stage disease, received brentuximab vedotin for two consecutive doses, followed by six cycles of AVD, followed by four more doses of brentuximab vedotin.[28]
    • The 2-year event-free survival rate was 80%, PFS rate was 84%, and OS rate was 93%.[28][Level of evidence C3]
    • Grade 3 or 4 toxicity was experienced by 42% of patients.

Summary of advanced-stage classic HL:

  • For patients with advanced-stage HL, six cycles of ABVD is the standard approach. In situations in which use of bleomycin is contraindicated, BV-AVD is a good option.
  • For patients with negative PET-CT scan results after the second cycle of ABVD, bleomycin may be omitted from the chemotherapy regimen with little loss of efficacy and improvement in tolerability.

Treatment of Recurrent Classic HL

More than one-half of all patients with recurrent Hodgkin lymphoma (HL) can achieve long-term disease-free survival (DFS), or even cure, using reinduction therapy followed by stem cell/bone marrow transplant consolidation.[1] In this regard, the disease follows a 75% rule: 75% of patients attain a clinical complete remission with salvage therapy reinduction, and then 75% of patients who undergo autologous stem cell transplant (SCT) are free of disease at 4 years. Poor prognostic factors include the following:[2,3,4]

  • Primary refractory disease (worst prognosis).
  • Relapse less than 12 months after initial therapy. Among patients who initially present with early-stage favorable disease that relapses, more than 75% have a relapse more than 12 months after diagnosis.[5]
  • Inability to attain a clinical complete remission after reinduction (i.e., positron emission tomography‒computed tomography [PET-CT] scan results are positive with a Deauville score of 4 or 5 followed by subsequent progression in the size and/or sites of disease).
  • B symptoms at relapse.
  • Extranodal disease at relapse.
  • More than two previous salvage regimens received.

Treatment Options for Recurrent Classic HL

Treatment options for recurrent classic HL:

  1. Pembrolizumab or nivolumab (alone or with chemotherapy).
  2. Brentuximab vedotin.
  3. Brentuximab vedotin plus nivolumab.
  4. Chemotherapy with stem cell transplant.
  5. Combination chemotherapy.
  6. Radiation therapy.

Pembrolizumab or nivolumab (alone or with chemotherapy)

The anti-programmed cell death-1 (PD-1) monoclonal antibodies pembrolizumab and nivolumab are immune checkpoint inhibitors.

Evidence: (pembrolizumab):

  1. In a phase II trial of 37 patients with relapsed or refractory disease, patients received three cycles of pembrolizumab with two cycles of ICE chemotherapy (ifosfamide, carboplatin, and etoposide) every 21 days prior to autologous SCT.[6][Level of evidence C3]
    • The complete response rate was 86.5% (95% confidence interval [CI], 71.2%–95.5%), and the overall response rate was 97.3%. There was no impairment in stem cell mobilization.
  2. A phase II trial included 39 patients with transplant-eligible relapsed or refractory disease. Patients received pembrolizumab with GVD chemotherapy (gemcitabine, vinorelbine, and liposomal doxorubicin).[7]
    • With a median follow-up of 13.5 months, the overall response rate was 100%, and the complete response rate was 95%.[7][Level of evidence C3]
    • Thirty-six patients (35%) proceeded to autologous SCT consolidation.
  3. A prospective randomized trial included 304 patients with relapsed or refractory disease who were ineligible for or had a relapse after autologous SCT. Patients were assigned to receive either pembrolizumab or brentuximab vedotin.[8]
    • With a median follow-up of 25.7 months, the median progression-free survival (PFS) for patients who received pembrolizumab was 13.2 months (95% CI, 10.9–19.4) versus 8.3 months (95% CI, 5.7–8.8) for patients who received brentuximab vedotin (hazard ratio [HR], 0.65; 95% CI, 0.48–0.88; P = .0027).[8][Level of evidence B1]
    • Serious treatment-related adverse events occurred in 16% of patients who received pembrolizumab and 11% of patients who received brentuximab vedotin.
  4. Studies of patients with relapsed HL treated with pembrolizumab reported the following:[9,10][Level of evidence C3]
    • The overall response rate was 64% to 74%, with a complete response rate of 22.4% (95% CI, 6.9%–28.6%).
    • Pembrolizumab was well tolerated by patients and can be used to achieve a clinical complete remission before autologous or allogeneic SCT.
    • The U.S. Food and Drug Administration (FDA) approved pembrolizumab for use in cases of refractory disease or relapse after three or more lines of therapy.

Evidence (nivolumab alone or nivolumab plus ICE):

  1. Studies of patients with relapsed HL treated with nivolumab reported the following:[11,12,13][Level of evidence C3]
    • The overall response rate was 65% to 87% and the complete response rate was 16% to 28%, with response durations usually exceeding 1 year for patients with heavily pretreated, relapsed disease.
    • Nivolumab was well tolerated by patients and can be used to achieve a clinical complete remission before autologous or allogeneic SCT.
    • The FDA approved nivolumab for use after both relapse from SCT and previous exposure to brentuximab vedotin. Nivolumab is also approved if the patient has received three different previous treatments, including SCT.
  2. In a phase II trial, nivolumab was given for 3 months. Patients who achieved a complete response proceeded to autologous SCT, while patients with disease in partial response or less received NICE (nivolumab, ifosfamide, carboplatin, and etoposide).[14]
    • Nivolumab induction was given to 34 patients, and 9 patients needed NICE because the complete response rate was 71% for nivolumab. After all therapy, the overall response rate was 93%, and the complete response rate was 91%. The 2-year PFS rate was 72%, and the 2-year OS rate was 95%.[14][Level of evidence C3]

Brentuximab vedotin

Brentuximab vedotin is an antibody-drug conjugate directed against CD30.[15,16,17] CD30 is a target for therapy because it is expressed on malignant Reed-Sternberg cells of HL but has limited expression on normal cells. Brentuximab vedotin is well tolerated by patients and can be used to achieve a clinical complete response before autologous or allogeneic SCT.

Evidence (brentuximab vedotin):

  1. In multiple trials for patients with relapsed disease, including one trial performed after allogeneic SCT, the following results were observed:
    • For patients with relapsing disease, response rates were approximately 75%. Complete remission rates were approximately 50% and median PFS was 4 to 8 months.[15,16,17,18,19][Level of evidence C3]
  2. Twenty-seven previously untreated patients older than 60 years, judged by the investigator to be in poor condition and unable to undergo chemotherapy, received brentuximab vedotin.[20]
    • A 92% overall response rate and 73% complete remission rate were reported.[20][Level of evidence C3]
  3. Retreatment with brentuximab vedotin was successful in patients with relapsed disease, with a response rate of 60%.[21][Level of evidence C3]
  4. For 329 patients at high risk of residual HL after SCT, the double-blind AETHERA trial (NCT01100502) evaluated brentuximab vedotin versus placebo.[22,23]
    • With a median follow-up of 5.0 years, the 5-year PFS rate for brentuximab vedotin was 59% (95% CI, 51%–66%) versus 41% (95% CI, 33%–49%) for placebo (HR, 0.521; 95% CI, 0.379–0.717).[22,23][Level of evidence B1]
    • The 16-month treatment duration after transplant was not achieved by most patients because they developed progressive peripheral neuropathy, which was partially reversible after discontinuation of brentuximab vedotin.
  5. In two phase I/II studies, 120 patients with relapsed or refractory HL received brentuximab vedotin and bendamustine.[24]
    • After two cycles, the objective response rates were 93% and 78%, and the complete remission rates were 74% and 32%.[24,25][Level of evidence C3]

Brentuximab vedotin plus nivolumab

Evidence (brentuximab vedotin plus nivolumab):

  1. In a phase II trial, 91 patients with relapsed or refractory HL received brentuximab vedotin and nivolumab.[26] Prior brentuximab vedotin therapy was allowed if the patient was not resistant or intolerant to the drug.
    • With a median follow-up of 34.3 months, the overall response rate was 85%, and the complete response rate was 67%. The 3-year PFS rate was 77% (95% CI, 65%–86%) for all patients and 91% (95% CI, 79%–96%) for those who received autologous SCT. The 3-year OS rate was 93% (95% CI, 85%–97%).[26][Level of evidence C3]
    • In this trial, 16% of patients had adverse events that required treatment with steroids.
  2. In a phase I/II study of 59 patients with relapsed or refractory HL, the combination of nivolumab and brentuximab vedotin was well tolerated (<10% of patients required systemic steroids).[27][Level of evidence C3]
    • With a median follow-up of 28.9 months, the 18-month PFS rate was 94% (95% CI, 84%–98%).
    • Adverse events included peripheral neuropathy (53%), neutropenia (42%), and immune-related events requiring corticosteroids (29%).[27]

Chemotherapy with stem cell transplant

Patients whose HL relapses after initial combination chemotherapy can undergo reinduction with the same or another chemotherapy regimen followed by high-dose chemotherapy and autologous bone marrow or peripheral stem cell or allogeneic bone marrow rescue.[1,28,29,30,31] This therapy has resulted in 3- to 4-year DFS rates of up to 50%. Patients who are responsive to reinduction therapy may have a better prognosis after subsequent autologous SCT; in one analysis, the 3-year event-free survival (EFS) rate was 80% with negative PET-CT scan results and 29% with positive PET-CT scan results.[32]

Patients who do not respond to induction chemotherapy (about 20%‒25% of all presenting patients) have survival rates lower than 10% at 8 years.[3] For these patients, high-dose chemotherapy and autologous bone marrow or peripheral stem cell or allogeneic bone marrow rescue [28,29,33,34,35] have resulted in 5-year DFS rates of around 25% to 30%, but selection bias clearly influences these numbers.[28,29,34,36,37]

In a retrospective review of 105 patients, those older than 60 years fared better with a combination of chemotherapy and salvage radiation therapy than with the use of intensified transplant consolidation.[38][Level of evidence C3]

The use of HLA-matched sibling marrow (allogeneic transplant) results in lower relapse rates, but the benefit may be offset by increased toxic effects.[28,39,40] Reduced-intensity conditioning for allogeneic SCT is also under clinical evaluation.[41,42,43]

Evidence (chemotherapy with SCT):

  1. A randomized trial compared aggressive conventional chemotherapy versus high-dose chemotherapy with autologous hematopoietic SCT for relapsed chemosensitive HL.[44][Level of evidence B1]
    • This trial showed improvement in freedom from treatment failure at 3 years for the transplant arm (55%) versus the chemotherapy-alone arm (34%).[44]
    • No difference was observed in overall survival (OS).
  2. A Cochrane meta-analysis concluded that autologous SCT after reinduction chemotherapy improves relapse-free survival by 20% to 30% over chemotherapy alone, but without an OS benefit.[45][Level of evidence B1]
  3. In three retrospective reviews of patients who underwent autologous bone marrow transplant (ABMT) for relapsed or refractory disease, a comparison was made between those who received involved-field radiation therapy (IFRT) for residual masses after high-dose therapy and those who received no further treatment.[46,47,48]
    • Those who received IFRT had decreased local disease recurrence.
    • Normalization of fluorine F 18-fludeoxyglucose PET-CT scans after reinduction therapy predicted a much better outcome after SCT, with an EFS rate of 80% versus 29% in one phase II trial.[32][Level of evidence C2]

After completion of autologous SCT for recurrent HL, 329 patients were randomly assigned to receive brentuximab vedotin or placebo in a double-blind trial (AETHERA [NCT01100502]).[22,23]

  • With a median follow-up of 5.0 years, the 5-year PFS rate for brentuximab vedotin was 59% (95% CI, 51%–66%) versus 41% (95% CI, 33%–49%) for placebo (HR, 0.521; 95% CI, 0.379–0.717).[22,23][Level of evidence B1]
  • The 16-month treatment duration after transplant was not achieved by most patients because they developed progressive peripheral neuropathy, which was partially reversible after discontinuation of brentuximab vedotin.
  • It is unclear whether the results of this trial are applicable when brentuximab vedotin is employed before transplant, such as during reinduction after relapse or during initial therapy (presently under clinical evaluation).

A phase II trial reported a response rate higher than 50% for bendamustine in relapsing ABMT patients.[49][Level of evidence C3] For patients with recurrent disease after ABMT, weekly vinblastine therapy has provided palliation with minimal toxic effects.[50][Level of evidence C3]

Combination chemotherapy

For patients who experience a relapse after initial combination chemotherapy, prognosis is determined more by the duration of the first remission than by the specific induction or salvage combination chemotherapy regimen. Patients whose initial remission after chemotherapy was longer than 1 year (late relapse) have long-term survival rates of 22% to 71% with salvage chemotherapy.[2,3,4,51,52,53] Patients whose initial remission after chemotherapy was shorter than 1 year (early relapse) do much worse and have long-term survival rates of 11% to 46%.[2,3,54]

It is rare to see a patient who received only radiation therapy for initial treatment, but patients who experience a relapse after initial wide-field, high-dose radiation therapy have a good prognosis. Combination chemotherapy results in 10-year DFS rates of 57% to 81% and OS rates of 57% to 89%.[2,55,56,57]

Radiation therapy

For the small subgroup of patients with only limited nodal recurrence following initial chemotherapy, radiation therapy with or without additional chemotherapy may provide long-term survival for about 50% of these highly selected patients.[58,59]

Summary for sequencing therapies for recurrent classic HL

  • Patients whose disease recurs who have not received brentuximab vedotin or a checkpoint inhibitor should consider the combination of nivolumab and brentuximab vedotin.[26,60]
  • The combination of pembrolizumab plus ICE chemotherapy,[6] nivolumab plus ICE chemotherapy,[14] or pembrolizumab plus GVD chemotherapy [7] is an effective induction therapy prior to autologous SCT.
  • Consider allogeneic SCT for patients with primary refractory disease who achieved partial response or complete remission on salvage therapy.
  • Checkpoint inhibitors alone are useful palliative agents for older patients or patients with comorbidities that preclude SCT.

Treatment of Nodular Lymphocyte–Predominant HL (NLPHL)

Immunophenotypic differences distinguish NLPHL (CD15-, CD20+, CD30-) from lymphocyte-rich classic Hodgkin lymphoma (HL) (CD15+, CD20-, CD30+).[1,2] The largest retrospective report of 426 cases showed no significant difference in clinical response or outcome to standard therapies for these two subgroups when patients present with early-stage disease (stage I or II).[3][Level of evidence C1]

Patients with NLPHL have earlier-stage disease and longer survival than those with classic HL.[4,5] NLPHL is usually diagnosed in asymptomatic younger patients with cervical or inguinal lymph nodes; this usually occurs without mediastinal involvement. Unlike patients with classic HL, bulky disease, B symptoms, and contiguous spread are uncommon in patients with NLPHL.[6,7]

Treatment Options for NLPHL

Treatment options for NLPHL include the following:

  1. Watchful waiting/active surveillance.
  2. Radiation therapy (early stage).
  3. Chemotherapy (advanced stage).
  4. Rituximab.

Watchful waiting/active surveillance

Because of the favorable prognosis for NLPHL and the potential long-term side effects of therapy, studies have evaluated watchful waiting or active surveillance for patients with asymptomatic, low tumor burden disease.[8] In a retrospective comparison, 37 such patients managed with active surveillance had a 5-year progression-free survival (PFS) rate of 77%, versus 85% for patients receiving active treatment.[9][Level of evidence C3]

Radiation therapy

Limited-field radiation therapy is the most-common treatment approach for patients with early-stage disease. This histology is rare, but this approach is based on retrospective analysis spanning several decades.[5,10,11,12,13,14]

Patients with nonbulky lymphocyte–predominant disease presenting in unilateral high neck (above the thyroid notch) or epitrochlear locations require only involved-field radiation therapy (IFRT) after clinical staging.[15] A retrospective report of 426 cases of lymphocyte-predominant HL (including the nodular lymphocyte–predominant and lymphocyte-rich classic subtypes) showed that more patients died of acute and long-term treatment-related toxicity than of recurrent HL.[3][Level of evidence C1] Limitation of radiation dose and radiation fields and avoidance of leukemogenic chemotherapeutic agents, along with watchful waiting policies, should be investigated for these subgroups.[14,16]

Chemotherapy

For patients with early-stage NLPHL, ABVD (doxorubicin, bleomycin, vinblastine, and dacarbazine) for two to three cycles has been combined with IFRT on the basis of anecdotal single-arm trials.[5,17]

For patients with advanced-stage NLPHL, chemotherapy regimens designed for patients with non-Hodgkin lymphomas, such as R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone) or R-CVP (rituximab, cyclophosphamide, vincristine, and prednisone), may be preferred, based on two retrospective reviews and a phase II study.[7,18,19,20][Level of evidence C3]

Rituximab

In a phase II trial of 39 patients with previously untreated and relapsed NLPHL, most of whom had advanced-stage disease, treatment with rituximab yielded a 100% response rate. With a median follow-up of 9.8 years, the median PFS was 3.0 years for patients who received rituximab induction only and 5.6 years for patients who received rituximab induction plus rituximab maintenance.[21][Level of evidence C2] With induction only, 9 of 23 patients had disease relapse with an aggressive B-cell lymphoma.

Follow-Up

Despite a usually favorable prognosis, there is a tendency for histological transformation of NLPHL to diffuse large B-cell lymphoma or T-cell–rich large B-cell lymphoma in approximately 10% of patients by 10 years.[6,21,22] This propensity of NLPHL to transform to aggressive B-cell lymphoma underscores the importance of long-term follow-up and rebiopsy at relapse.[21,23]

With a median follow-up of 7 to 8 years, more patients died of treatment-related toxic effects (acute and long-term) than of recurrent HL. Limitation of radiation dose and fields and avoidance of leukemogenic chemotherapeutic agents, along with watchful waiting policies, should be investigated for these subgroups.[5,16,24]

The treatment approach for relapsing disease is similar to that for recurrent follicular lymphoma. Based on age and performance status, some patients receive sequential therapies and watchful waiting, and some patients receive aggressive salvage chemoimmunotherapy (like R-ICE [rituximab, ifosfamide, carboplatin, and etoposide]) followed by stem cell transplant.[7,25,26]

Treatment of HL During Pregnancy

Introduction

Hodgkin lymphoma (HL) affects primarily young women, some of whom may be pregnant. When treating a pregnant woman, an oncologist will provide therapy that minimizes risk to the fetus. Treatment choice must be individualized, taking into consideration the following:

  • The mother's wishes.
  • The severity and aggressiveness of the HL.
  • The trimester of the pregnancy.

Stage Information for HL During Pregnancy

To avoid exposing a pregnant woman to ionizing radiation, magnetic resonance imaging is the preferred method for staging evaluation.[1] The presenting stage, clinical behavior, prognosis, and histological subtypes of HL in pregnant women do not differ from those in nonpregnant women during their childbearing years.[2] For more information, see the Stage Information for HL section.

Treatment Options for HL During Pregnancy

Treatment options for HL during pregnancy include the following:

  1. Watchful waiting.
  2. Radiation therapy.
  3. Chemotherapy.

In one study, the 20-year survival rate of pregnant women with HL did not differ from the 20-year survival rate of nonpregnant women who were matched for similar stage of disease, age at diagnosis, and calendar year of treatment.[3]

The long-term effects on progeny after chemotherapy in utero are unknown, although evidence seems promising.[3,4,5,6,7]

Based on anecdotal series, there is no evidence that a pregnancy after completion of therapy increases the relapse rate for patients in remission.[8,9]

Therapy during the first trimester

HL that is diagnosed in the first trimester of pregnancy does not constitute an absolute indication for therapeutic abortion. Treatment options for each patient must take into account disease stage, rapidity of growth of the lymphoma, and the patient's wishes.[10]

Watchful waiting

If the HL presents in early stage above the diaphragm and is growing slowly, patients can be observed carefully, with plans to induce delivery early and proceed with definitive therapy.[11]

Radiation therapy

Alternatively, these patients can receive radiation therapy with proper shielding.[12,13,14,15] Investigators at the MD Anderson Cancer Center reported no congenital abnormalities in 16 babies delivered after the mothers had received supradiaphragmatic radiation while the uterus was shielded with five half-value layers of lead.[16] Because of theoretical risks of the fetus developing future malignancies from even minimal scattered radiation doses outside the radiation field, postponing radiation therapy—if possible, until after delivery—should be considered.[17]

Chemotherapy

Evidence (chemotherapy during the first trimester):

  1. Chemotherapy that is administered in the first trimester has been associated with congenital abnormalities in as many as 33% of infants.[4,18] Consequently, some women may opt to continue the pregnancy and agree to radiation therapy or chemotherapy if immediate treatment is required after the first trimester.
  2. A multicenter retrospective analysis of 40 patients described pregnancy termination in 3 patients, deferral of therapy to postpartum in 13 patients (median 30-week gestation), and antenatal therapy applied to the remaining 24 patients (median 21-week gestation, all done after the first trimester).[19]
    • With a median follow-up of 41 months, the 3-year progression-free survival (PFS) rate was 85%, and the overall survival (OS) rate was 97%, often with the use of ABVD (doxorubicin, bleomycin, vinblastine, and dacarbazine).[19][Level of evidence C3]
  3. A retrospective analysis of 39 patients from the MD Anderson Cancer Center described pregnancy termination in 3 patients, deferral of therapy to the postpartum period in 12 patients, and antenatal therapy applied to 24 patients.[20]
    • Two women miscarried after receiving doxorubicin-based chemotherapy in the first trimester.
    • With a median follow-up of 68 months from diagnosis, the 5-year PFS rate was 75%, and the OS rate was 82%. These rates did not differ between the antenatal and postpartum timing of therapy.[20][Level of evidence C3]

Therapy later in pregnancy

Watchful waiting

In the second half of pregnancy, patients can be observed carefully, and therapy can be postponed until induction of delivery at 32 to 36 weeks.[6,7,18]

Radiation therapy

As an alternative, a short course of radiation therapy can be used before delivery in cases of respiratory compromise caused by a rapidly enlarging mediastinal mass.

Chemotherapy

If chemotherapy is mandatory before delivery—such as for patients with symptomatic advanced-stage disease—vinblastine alone, given intravenously at 6 mg/m² every 2 weeks until induction of delivery, may be considered because it has not been associated with fetal abnormalities in the second half of pregnancy.[6,7] Combination chemotherapy with ABVD appears to be safe in the second half of pregnancy.[5] If chemotherapy is required after the first trimester, many clinicians prefer the combination of drugs over single-agent drugs or radiation therapy. Steroids are employed both for their antitumor effect and for hastening fetal pulmonary maturity.

Latest Updates to This Summary (04 / 18 / 2024)

The PDQ cancer information summaries are reviewed regularly and updated as new information becomes available. This section describes the latest changes made to this summary as of the date above.

Treatment of Early Favorable Classic Hodgkin Lymphoma (HL)

Added Federico et al. as reference 17.

Revised text to state that two trials of chemotherapy with or without radiation therapy showed an increased risk of relapse when radiation therapy was omitted. In the EORTC/LYSA/FIL H10 trial, the 10-year progression-free survival (PFS) rate was 98.8% with three cycles of ABVD (doxorubicin, bleomycin, vinblastine, and dacarbazine) plus radiation therapy and 85.4% with four cycles of ABVD without radiation therapy.

Revised text to state that the 7% to 13% difference in PFS shown in studies without a difference in overall survival can be seen either as a mandate to combine radiation therapy with ABVD to avoid recurrences or as a rationale to give four or more cycles of AVBD when omitting radiation therapy.

Treatment of Advanced Classic HL

Added Luminari et al. as reference 26.

Revised text about the results of the RATHL study to state that with a median follow-up of 7.3 years for the 937 patients with negative positron emission tomography (PET)–computed tomography results, there was no difference in the 7-year overall survival rate. The absolute difference in the 3-year PFS rate was 1.3%, which falls within the predefined noninferiority margin. This means that there was no PFS advantage for continuing bleomycin for PET-negative patients on the interim scan.
