Abstract/Text: BACKGROUND: Two thirds of patients with advanced Hodgkin's disease are cured with current approaches to treatment. Prediction of the outcome is important to avoid overtreating some patients and to identify others in whom standard treatment is likely to fail.
METHODS: Data were collected from 25 centers and study groups on a total of 5141 patients treated with combination chemotherapy for advanced Hodgkin's disease, with or without radiotherapy. The data included the outcome and 19 demographic and clinical characteristics at diagnosis. The end point was freedom from progression of disease. Complete data were available for 1618 patients; the final Cox model was fitted to these data. Data from an additional 2643 patients were used for partial validation.
RESULTS: The prognostic score was defined as the number of adverse prognostic factors present at diagnosis. Seven factors had similar independent prognostic effects: a serum albumin level of less than 4 g per deciliter, a hemoglobin level of less than 10.5 g per deciliter, male sex, an age of 45 years or older, stage IV disease (according to the Ann Arbor classification), leukocytosis (a white-cell count of at least 15,000 per cubic millimeter), and lymphocytopenia (a lymphocyte count of less than 600 per cubic millimeter, a count that was less than 8 percent of the white-cell count, or both). The score predicted the rate of freedom from progression of disease as follows: 0, or no factors (7 percent of the patients), 84 percent; 1 (22 percent of the patients), 77 percent; 2 (29 percent of the patients), 67 percent; 3 (23 percent of the patients), 60 percent; 4 (12 percent of the patients), 51 percent; and 5 or higher (7 percent of the patients), 42 percent.
CONCLUSIONS: The prognostic score we developed may be useful in designing clinical trials for the treatment of advanced Hodgkin's disease and in making individual therapeutic decisions, but a distinct group of patients at very high risk could not be identified on the basis of routinely documented demographic and clinical characteristics.

Abstract/Text: BACKGROUND: Treatment of early-stage Hodgkin's disease is usually tailored in line with prognostic factors that allow for reductions in the amount of chemotherapy and extent of radiotherapy required for a possible cure.
METHODS: From 1993 to 1999, we identified 1538 patients (age, 15 to 70 years) who had untreated stage I or II supradiaphragmatic Hodgkin's disease with favorable prognostic features (the H8-F trial) or unfavorable features (the H8-U trial). In the H8-F trial, we compared three cycles of mechlorethamine, vincristine, procarbazine, and prednisone (MOPP) combined with doxorubicin, bleomycin, and vinblastine (ABV) plus involved-field radiotherapy with subtotal nodal radiotherapy alone (reference group). In the H8-U trial, we compared three regimens: six cycles of MOPP-ABV plus involved-field radiotherapy (reference group), four cycles of MOPP-ABV plus involved-field radiotherapy, and four cycles of MOPP-ABV plus subtotal nodal radiotherapy.
RESULTS: The median follow-up was 92 months. In the H8-F trial, the estimated 5-year event-free survival rate was significantly higher after three cycles of MOPP-ABV plus involved-field radiotherapy than after subtotal nodal radiotherapy alone (98% vs. 74%, P<0.001). The 10-year overall survival estimates were 97% and 92%, respectively (P=0.001). In the H8-U trial, the estimated 5-year event-free survival rates were similar in the three treatment groups: 84% after six cycles of MOPP-ABV plus involved-field radiotherapy, 88% after four cycles of MOPP-ABV plus involved-field radiotherapy, and 87% after four cycles of MOPP-ABV plus subtotal nodal radiotherapy. The 10-year overall survival estimates were 88%, 85%, and 84%, respectively.
CONCLUSIONS: Chemotherapy plus involved-field radiotherapy should be the standard treatment for Hodgkin's disease with favorable prognostic features. In patients with unfavorable features, four courses of chemotherapy plus involved-field radiotherapy should be the standard treatment. (ClinicalTrials.gov number, NCT00379041 [ClinicalTrials.gov].).

Abstract/Text: BACKGROUND: Whether it is possible to reduce the intensity of treatment in early (stage I or II) Hodgkin's lymphoma with a favorable prognosis remains unclear. We therefore conducted a multicenter, randomized trial comparing four treatment groups consisting of a combination chemotherapy regimen of two different intensities followed by involved-field radiation therapy at two different dose levels.
METHODS: We randomly assigned 1370 patients with newly diagnosed early-stage Hodgkin's lymphoma with a favorable prognosis to one of four treatment groups: four cycles of doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) followed by 30 Gy of radiation therapy (group 1), four cycles of ABVD followed by 20 Gy of radiation therapy (group 2), two cycles of ABVD followed by 30 Gy of radiation therapy (group 3), or two cycles of ABVD followed by 20 Gy of radiation therapy (group 4). The primary end point was freedom from treatment failure; secondary end points included efficacy and toxicity of treatment.
RESULTS: The two chemotherapy regimens did not differ significantly with respect to freedom from treatment failure (P=0.39) or overall survival (P=0.61). At 5 years, the rates of freedom from treatment failure were 93.0% (95% confidence interval [CI], 90.5 to 94.8) with the four-cycle ABVD regimen and 91.1% (95% CI, 88.3 to 93.2) with the two-cycle regimen. When the effects of 20-Gy and 30-Gy doses of radiation therapy were compared, there were also no significant differences in freedom from treatment failure (P=1.00) or overall survival (P=0.61). Adverse events and acute toxic effects of treatment were most common in the patients who received four cycles of ABVD and 30 Gy of radiation therapy (group 1).
CONCLUSIONS: In patients with early-stage Hodgkin's lymphoma and a favorable prognosis, treatment with two cycles of ABVD followed by 20 Gy of involved-field radiation therapy is as effective as, and less toxic than, four cycles of ABVD followed by 30 Gy of involved-field radiation therapy. Long-term effects of these treatments have not yet been fully assessed. (Funded by the Deutsche Krebshilfe and the Swiss Federal Government; ClinicalTrials.gov number, NCT00265018.)

Abstract/Text: BACKGROUND AND METHODS: MOPP (mechlorethamine, vincristine, procarbazine, and prednisone) has been the standard treatment for Hodgkin's disease for almost 20 years. In a randomized, multicenter trial, we compared three regimens of primary systemic therapy for newly diagnosed advanced Hodgkin's disease in Stages IIIA2, IIIB, and IVA or IVB: (1) MOPP alone given for 6 to 8 cycles, (2) MOPP alternating with ABVD (doxorubicin, bleomycin, vinblastine, and dacarbazine) for 12 cycles, and (3) ABVD alone for 6 to 8 cycles. Patients in a first relapse after radiation therapy were eligible. No additional radiation therapy was given. Patients who did not have a complete response or who had a relapse with either MOPP alone or ABVD alone were switched to the opposite regimen.
RESULTS: Of 361 eligible patients, 123 received MOPP, 123 received MOPP alternating with ABVD, and 115 received ABVD alone. The patients were stratified according to age, stage, previous radiation, histologic features, and performance status. The overall response rate was 93 percent, with complete responses in 77 percent: 67 percent in the MOPP group, 82 percent in the ABVD group, and 83 percent in the MOPP-ABVD group (P = 0.006 for the comparison of MOPP with the other two regimens, both of which contained doxorubicin). The rates of failure-free survival at five years were 50 percent for MOPP, 61 percent for ABVD, and 65 percent for MOPP-ABVD. Age, stage (III vs. IV), and regimen influenced failure-free survival significantly. Overall survival at five years was 66 percent for MOPP, 73 percent for ABVD, and 75 percent for MOPP-ABVD (P = 0.28 for the comparison of MOPP with the doxorubicin regimens). MOPP had more severe toxic effects on bone marrow than ABVD and was associated with greater reductions in the prescribed dose.
CONCLUSIONS: In this trial, ABVD therapy for 6 to 8 months was as effective as 12 months of MOPP alternating with ABVD, and both were superior to MOPP alone in the treatment of advanced Hodgkin's disease. ABVD was less myelotoxic than MOPP or ABVD alternating with MOPP.

Abstract/Text: BACKGROUND: BEACOPP, an intensified regimen consisting of bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone, has been advocated as the new standard of treatment for advanced Hodgkin's lymphoma, in place of the combination of doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD).
METHODS: We randomly assigned 331 patients with previously untreated and unfavorable Hodgkin's lymphoma (stage IIB, III, or IV, or an international prognostic score of ≥3 on a scale of 0 to 7, with higher scores indicating increased risk), to receive either BEACOPP or ABVD, each followed by local radiotherapy when indicated. Patients with residual or progressive disease after the initial therapy were to be treated according to a state-of-the-art high-dose salvage program. The median follow-up period was 61 months.
RESULTS: The 7-year rate of freedom from first progression was 85% among patients who had received initial treatment with BEACOPP and 73% among those who had received initial treatment with ABVD (P=0.004), and the 7-year rate of event-free survival was 78% and 71%, respectively (P=0.15). A total of 65 patients (20 in the BEACOPP group, and 45 in the ABVD group) went on to receive the intended high-dose salvage regimen. As of the cutoff date, 3 of the 20 patients in the BEACOPP group and 15 of the 45 in the ABVD group who had had progressive disease or relapse after the initial therapy were alive and free of disease. After completion of the overall planned treatment, including salvage therapy, the 7-year rate of freedom from a second progression was 88% in the BEACOPP group and 82% in the ABVD group (P=0.12), and the 7-year rate of overall survival was 89% and 84%, respectively (P=0.39). Severe adverse events occurred more frequently in the BEACOPP group than in the ABVD group.
CONCLUSIONS: Treatment with BEACOPP, as compared with ABVD, resulted in better initial tumor control, but the long-term clinical outcome did not differ significantly between the two regimens. (Funded by Fondazione Michelangelo; ClinicalTrials.gov number, NCT01251107.).

Abstract/Text: BACKGROUND: High-dose chemotherapy followed by transplantation of autologous haemopoietic stem cells (BEAM-HSCT) is frequently used to treat patients with relapsed Hodgkin's disease. We aimed to compare this treatment with conventional aggressive chemotherapy without stem-cell transplantation (Dexa-BEAM).
METHODS: 161 patients between 16 and 60 years of age with relapsed Hodgkin's disease were randomly assigned two cycles of Dexa-BEAM (dexamethasone and carmustine, etoposide, cytarabine, and melphalan) and either two further courses of Dexa-BEAM or high-dose BEAM and transplantation of haemopoietic stem cells. Only patients with chemosensitive disease (complete or partial remission after two courses of Dexa-BEAM) proceeded to further treatment. The primary endpoint was freedom from treatment failure for patients with chemosensitive disease. Analysis was per protocol.
FINDINGS: 17 patients were excluded from the study after randomisation (ten given Dexa-BEAM and seven given BEAM-HSCT). Median follow-up was 39 months (IQR 3-78). Freedom from treatment failure at 3 years was significantly better for patients given BEAM-HSCT (55%) than for those on Dexa-BEAM (34%; difference -21%, 95% CI -39.87 to -2.13; p=0.019). Overall survival of patients given either treatment did not differ significantly.
INTERPRETATION: High-dose BEAM and transplantation of haemopoietic stem cells improves freedom from treatment failure in patients with chemosensitive first relapse of Hodgkin's disease irrespective of length of initial remission.

Abstract/Text: PURPOSE: Starting from November 2001, 260 newly diagnosed patients with Hodgkin's lymphoma (HL) were consecutively enrolled in parallel Italian and Danish prospective trials to evaluate the prognostic role of an early interim 2-[(18)F]fluoro-2-deoxy-D-glucose positron emission tomography (FDG-PET) scan and the International Prognostic Score (IPS) in advanced HL, treated with conventional ABVD (doxorubicin, bleomycin, vinblastine, and dacarbazine) therapy.
PATIENTS AND METHODS: Most patients (n = 190) presented with advanced disease (stages IIB through IVB), whereas 70 presented in stage IIA with adverse prognostic factors. All but 11 patients were treated with standard ABVD therapy followed by consolidation radiotherapy in case of bulky presentation or residual tumor mass. Conventional radiologic staging was performed at baseline. FDG-PET scan was performed at baseline and after two courses of ABVD (PET-2). No treatment change was allowed on the basis of the PET-2 results.
RESULTS: After a median follow-up of 2.19 years (range, 0.32 to 5.18 years), 205 patients were in continued complete remission and two patients were in partial remission. Forty-three patients progressed during therapy or immediately after, whereas 10 patients relapsed. The 2-year progression-free survival for patients with positive PET-2 results was 12.8% and for patients with negative PET-2 results was 95.0% (P < .0001). In univariate analysis, the treatment outcome was significantly associated with PET-2 (P < .0001), stage IV (P < .0001), WBC more than 15,000 (P < .0001), lymphopenia (P < .001), IPS as a continuous variable (P < .0001), extranodal involvement (P < .0001), and bulky disease (P = .012). In multivariate analyses, only PET-2 turned out to be significant (P < .0001).
CONCLUSION: PET-2 overshadows the prognostic value of IPS and emerges as the single most important tool for planning of risk-adapted treatment in advanced HL.

Abstract/Text: Presented here are the 5-year end-of-study results from the pivotal phase 2 trial of brentuximab vedotin in patients with relapsed/refractory (R/R) Hodgkin lymphoma (HL) after failed hematopoietic autologous stem cell transplantation. At 5 years, the overall patient population (N = 102) had an estimated overall survival (OS) rate of 41% (95% confidence interval [CI]: 31-51) and progression-free survival (PFS) rate of 22% (95% CI: 13-31). Patients who achieved a complete response (CR) to brentuximab vedotin (N = 34) had estimated OS and PFS rates of 64% (95% CI: 48-80%) and 52% (95% CI: 34-69%), respectively. The median OS and PFS were not reached in CR patients, with 13 patients (38% of all CR patients) remaining in follow-up and in remission at study closure. Of the 13 patients, 4 received consolidative hematopoietic allogeneic stem cell transplant, and 9 (9% of all enrolled patients) remain in sustained CR without receiving any further anticancer therapy after treatment with brentuximab vedotin. Of the patients who experienced treatment-emergent peripheral neuropathy, 88% experienced either resolution (73%) or improvement (14%) in symptoms. These 5-year follow-up data demonstrate that a subset of patients with R/R HL who obtained CR with single-agent brentuximab vedotin achieved long-term disease control and may potentially be cured. The trial was registered at www.clinicaltrials.gov as #NCT00848926.

Abstract/Text: BACKGROUND: Malignant cells of classical Hodgkin's lymphoma are characterised by genetic alterations at the 9p24.1 locus, leading to overexpression of PD-1 ligands and evasion of immune surveillance. In a phase 1b study, nivolumab, a PD-1-blocking antibody, produced a high response in patients with relapsed and refractory classical Hodgkin's lymphoma, with an acceptable safety profile. We aimed to assess the clinical benefit and safety of nivolumab monotherapy in patients with classical Hodgkin's lymphoma after failure of both autologous stem-cell transplantation and brentuximab vedotin.
METHODS: In this ongoing, single-arm phase 2 study, adult patients (aged ≥18 years) with recurrent classical Hodgkin's lymphoma who had failed to respond to autologous stem-cell transplantation and had either relapsed after or failed to respond to brentuximab vedotin, and with an Eastern Cooperative Oncology Group performance status score of 0 or 1, were enrolled from 34 hospitals and academic centres across Europe and North America. Patients were given nivolumab intravenously over 60 min at 3 mg/kg every 2 weeks until progression, death, unacceptable toxicity, or withdrawal from study. The primary endpoint was objective response following a prespecified minimum follow-up period of 6 months, assessed by an independent radiological review committee (IRRC). All patients who received at least one dose of nivolumab were included in the primary and safety analyses. This trial is registered with ClinicalTrials.gov, number NCT02181738.
FINDINGS: Among 80 treated patients recruited between Aug 26, 2014, and Feb 20, 2015, the median number of previous therapies was four (IQR 4-7). At a median follow-up of 8·9 months (IQR 7·8-9·9), 53 (66·3%, 95% CI 54·8-76·4) of 80 patients achieved an IRRC-assessed objective response. The most common drug-related adverse events (those that occurred in ≥15% of patients) included fatigue (20 [25%] patients), infusion-related reaction (16 [20%]), and rash (13 [16%]). The most common drug-related grade 3 or 4 adverse events were neutropenia (four [5%] patients) and increased lipase concentrations (four [5%]). The most common serious adverse event (any grade) was pyrexia (three [4%] patients). Three patients died during the study; none of these deaths were judged to be treatment related.
INTERPRETATION: Nivolumab resulted in frequent responses with an acceptable safety profile in patients with classical Hodgkin's lymphoma who progressed after autologous stem-cell transplantation and brentuximab vedotin. Therefore, nivolumab might be a new treatment option for a patient population with a high unmet need. Ongoing follow-up will help to assess the durability of response.

Abstract/Text: BACKGROUND: Five-year follow-up in a trial involving patients with previously untreated stage III or IV classic Hodgkin's lymphoma showed long-term progression-free survival benefits with first-line therapy with brentuximab vedotin, a CD30-directed antibody-drug conjugate, plus doxorubicin, vinblastine, and dacarbazine (A+AVD), as compared with doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD). A planned interim analysis indicated a potential benefit with regard to overall survival; data from a median of 6 years of follow-up are now available.
METHODS: We randomly assigned patients in a 1:1 ratio to receive up to six cycles of A+AVD or ABVD. The primary end point, modified progression-free survival, has been reported previously. The key secondary end point was overall survival in the intention-to-treat population. Safety was also assessed.
RESULTS: A total of 664 patients were assigned to receive A+AVD and 670 to receive ABVD. At a median follow-up of 73.0 months, 39 patients in the A+AVD group and 64 in the ABVD group had died (hazard ratio, 0.59; 95% confidence interval [CI], 0.40 to 0.88; P = 0.009). The 6-year overall survival estimates were 93.9% (95% CI, 91.6 to 95.5) in the A+AVD group and 89.4% (95% CI, 86.6 to 91.7) in the ABVD group. Progression-free survival was longer with A+AVD than with ABVD (hazard ratio for disease progression or death, 0.68; 95% CI, 0.53 to 0.86). Fewer patients in the A+AVD group than in the ABVD group received subsequent therapy, including transplantation, and fewer second cancers were reported with A+AVD (in 23 vs. 32 patients). Primary prophylaxis with granulocyte colony-stimulating factor was recommended after an increased incidence of febrile neutropenia was observed with A+AVD. More patients had peripheral neuropathy with A+AVD than with ABVD, but most patients in the two groups had resolution or amelioration of the event by the last follow-up.
CONCLUSIONS: Patients who received A+AVD for the treatment of stage III or IV Hodgkin's lymphoma had a survival advantage over those who received ABVD. (Funded by Takeda Development Center Americas and Seagen; ECHELON-1 ClinicalTrials.gov number, NCT01712490; EudraCT number, 2011-005450-60.).

Abstract/Text: BACKGROUND: Chemotherapy plus radiation treatment is effective in controlling stage IA or IIA nonbulky Hodgkin's lymphoma in 90% of patients but is associated with late treatment-related deaths. Chemotherapy alone may improve survival because it is associated with fewer late deaths.
METHODS: We randomly assigned 405 patients with previously untreated stage IA or IIA nonbulky Hodgkin's lymphoma to treatment with doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) alone or to treatment with subtotal nodal radiation therapy, with or without ABVD therapy. Patients in the ABVD-only group, both those with a favorable risk profile and those with an unfavorable risk profile, received four to six cycles of ABVD. Among those assigned to subtotal nodal radiation therapy, patients who had a favorable risk profile received subtotal nodal radiation therapy alone and patients with an unfavorable risk profile received two cycles of ABVD plus subtotal nodal radiation therapy. The primary end point was 12-year overall survival.
RESULTS: The median length of follow-up was 11.3 years. At 12 years, the rate of overall survival was 94% among those receiving ABVD alone, as compared with 87% among those receiving subtotal nodal radiation therapy (hazard ratio for death with ABVD alone, 0.50; 95% confidence interval [CI], 0.25 to 0.99; P=0.04); the rates of freedom from disease progression were 87% and 92% in the two groups, respectively (hazard ratio for disease progression, 1.91; 95% CI, 0.99 to 3.69; P=0.05); and the rates of event-free survival were 85% and 80%, respectively (hazard ratio for event, 0.88; 95% CI, 0.54 to 1.43; P=0.60). Among the patients randomly assigned to ABVD alone, 6 patients died from Hodgkin's lymphoma or an early treatment complication and 6 died from another cause; among those receiving radiation therapy, 4 deaths were related to Hodgkin's lymphoma or early toxic effects from the treatment and 20 were related to another cause.
CONCLUSIONS: Among patients with Hodgkin's lymphoma, ABVD therapy alone, as compared with treatment that included subtotal nodal radiation therapy, was associated with a higher rate of overall survival owing to a lower rate of death from other causes.
