Escalated-Dose BEACOPP in the Treatment of Patients With Advanced-Stage Hodgkin's Lymphoma: 10 Years of Follow-Up of the GHSG HD9 Study

PURPOSE The HD9 trial of the German Hodgkin Study Group compared two different doses (baseline and escalated) of the bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone (BEACOPP) chemotherapy regimen in 1,196 patients with advanced-stage Hodgkins lymphoma (HL). The previous analysis with 5 years median follow-up had indicated improved tumor control with BEACOPP escalated. Since the long-term safety and efficacy of this regimen has been debated, we report the 10-year follow-up. PATIENTS AND METHODS Patients received one of three chemotherapy regimens: eight cycles of cyclophosphamide, vincristine, procarbazine, and prednisone (COPP) alternating with doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD); eight cycles of BEACOPP baseline; or eight cycles of BEACOPP escalated. RESULTS Median follow-up was 111 months. At 10 years, freedom from treatment failure (FFTF) was 64%, 70%, and 82% with OS rates of 75%, 80%, and 86% for patients treated with COPP/ABVD (arm A), BEACOPP baseline (arm B), and BEACOPP escalated (arm C), respectively (P < .001). BEACOPP escalated was significantly better than BEACOPP baseline in terms of FFTF (P < .0001) and OS (P = .0053). A total of 74 second malignancies (6.2%) were documented, including acute myeloid leukemia (0.4%, 1.5%, and 3.0%), non-Hodgkins lymphoma (2.7%, 1.7%, and 1.0%), and solid tumors (2.7%, 3.4%, and 1.9%). The corresponding overall secondary malignancy rates were 5.7%, 6.6%, and 6.0%, respectively. CONCLUSION The 10-year follow-up of the HD9 trial demonstrates a stabilized significant improvement in long-term FFTF and OS for BEACOPP escalated in advanced-stage HL. These results challenge ABVD as standard of care for this patient population.

New Prognostic Score Based on Treatment Outcome of Patients With Relapsed Hodgkin’s Lymphoma Registered in the Database of the German Hodgkin’s Lymphoma Study Group

PURPOSE To evaluate salvage treatment outcome of patients with relapsed Hodgkins disease (HD) and to distinguish different risk groups using identified prognostic factors. PATIENTS AND METHODS From 4,754 patients registered in the German Hodgkins Lymphoma Study Group (GHSG) database between 1988 and 1999, 422 patients with early (n = 170) or late (n = 252) relapsed HD were identified. One hundred seven patients (25%) relapsed after radiotherapy (RT) for early stages, 133 patients (32%) after combined-modality therapy for intermediate stages, and 182 patients (43%) after chemotherapy (CT) and RT to initial bulky disease or residual lymphoma for advanced stages. At relapse, characteristics of these 422 patients (median age, 38 years; range, 17 to 77) were stage III/IV, 45%; B symptoms, 24%; elevated erythrocyte sedimentation rate, 29%; anemia, 13%; and Karnofsky performance score, less than 90 in 13%. At first relapse, salvage treatment was RT in 13%, CT in 54%, and high-dose chemotherapy (HDCT) with autologous stem-cell transplantation (ASCT) in 33%. RESULTS Median follow-up time after relapse was 45 months. Freedom from second failure (FF2F) and overall survival (OS) were 81% and 89% for relapse after RT, 33% and 46% for early relapse after CT, and 43% and 71% for late relapse after CT, respectively. In multivariate analysis, independent risk factors were time to relapse, clinical stage at relapse, and anemia at relapse. Four subgroups with significantly different FF2F and OS were identified. The prognostic score was predictive for patients who relapsed after RT, CT with conventional CT salvage, and CT with HDCT/ASCT. CONCLUSION In the GHSG database, time to relapse and clinical stage and anemia at relapse are relevant factors and can be used to form a prognostic score for HD patients at relapse.

Positron emission tomography has a high negative predictive value for progression or early relapse for patients with residual disease after first-line chemotherapy in advanced-stage Hodgkin lymphoma

In the HD15 trial of the German Hodgkin Study Group, the negative predictive value (NPV) of positron emission tomography (PET) using [(18)F]-fluorodeoxyglucose in advanced-stage Hodgkin lymphoma (HL) was evaluated. A total of 817 patients were enrolled and randomly assigned to receive BEACOPP-based chemotherapy. After completion of chemotherapy, residual disease measuring more than or equal to 2.5 cm in diameter was assessed by PET in 311 patients. The NPV of PET was defined as the proportion of PET(-) patients without progression, relapse, or irradiation within 12 months after PET review panel. The progression-free survival was 96% for PET(-) patients (95% confidence interval [CI], 94%-99%) and 86% for PET(+) patients (95% CI, 78%-95%, P = .011). The NPV for PET in this analysis was 94% (95% CI, 91%-97%). Thus, consolidation radiotherapy can be omitted in PET(-) patients with residual disease without increasing the risk for progression or early relapse compared with patients in complete remission. The impact of this finding on the overall survival at 5 years must be awaited. Until then, response adapted therapy guided by PET for HL patients seems to be a promising approach that should be further evaluated in clinical trials. This trial is registered at http://isrctn.org study as #ISRCTN32443041.

Secondary Myeloid Leukemia and Myelodysplastic Syndromes in Patients Treated for Hodgkin’s Disease: A Report From the German Hodgkin’s Lymphoma Study Group

PURPOSE To assess the incidence and outcome of secondary acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS) in patients with Hodgkins disease (HD). PATIENTS AND METHODS Between 1981 and 1998, the GHSG conducted three trial generations for early, intermediate, and advanced HD involving a total of 5,411 patients (called HD1 through HD9). RESULTS A total of 46 patients with secondary AML/MDS were identified. The median age at diagnosis of leukemia was 47 years (range, 22 to 79 years). Primary therapy was as follows: radiotherapy alone (n = 4); doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD; n = 1); cyclophosphamide, vincristine, procarbazine, and prednisone (COPP)/ABVD or similar (n = 30); bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone (BEACOPP) baseline (n = 2); and BEACOPP escalated (n = 9). Twelve patients developed AML/MDS after salvage therapy, including four patients who developed AML/MDS after high-dose chemotherapy with autologous stem-cell transplantation. Thirty-six of the secondary malignancies were AML, and 10 malignancies were MDS. After a median observation time of 55 months, incidence of secondary AML/MDS was 1%. Treatment for secondary AML/MDS was as follows: cytarabine (Ara-C)-containing regimens (6-thioguanin, cytarabine, daunorubicin [TAD]/high-dose cytarabine, mitoxantrone [HAM], HAM, Ida-Ara-C (idarubicin + Ara-C), Ida-Flag (idarubicin, fludarabin, Ara-C, G-CSF), and idarubicin, cytarabine, etoposide [ICE]+HAM; n = 11), TAD-chemotherapy (n = 5), other regimens (n = 3), no treatment or supportive care (n = 24), palliative oral chemotherapy (n = 3), and allogeneic stem cell transplantation (n = 9). After 24 months of observation, no difference in freedom from treatment failure and overall survival (2% and 8%, respectively) was observed in patients who developed AML or MDS. CONCLUSION The prognosis of patients with secondary AML/MDS after primary HD is poor. Thus, emphasis should be made to improve initial treatment in an attempt to prevent this complication.

Whole-body positron emission tomography using 18F-fluorodeoxyglucose for initial staging of patients with Hodgkin's disease

Abstract. An accurate initial staging of patients with Hodgkins disease (HD) is important for the evaluation of clinical stage and risk factors, which are crucial for the choice of an appropriate treatment. 18F-fluorodeoxyglucose (FDG) positron emission tomography (PET) is useful for detecting active tumor tissue in patients with lymphoproliferative diseases and may contribute to conventional staging methods in patients with HD. Twenty-two patients who presented with newly diagnosed HD underwent conventional staging methods including computed tomography (CT) as well as FDG PET. Lesions apparent in FDG PET and CT were correlated to each other. Seventy-seven lesions were observed either in PET or CT or in both. In 48 (62%) lesions PET and CT were both positive. In 20 (26%) sites, PET was positive and CT negative. Of 22 patients (18%) 4 were upstaged due to these positive PET findings, and as a result one patient received a different therapeutic regimen. PET failed to detect nine (12%) CT-positive sites in six patients. Statistically, these data are reflected by a sensitivity for PET and CT of 88% and 74%, respectively. Specificity of both imaging modalities was 100%. PET can contribute valuable information as an additional staging examination and led to an upstaging in some patients with primary HD. However, PET should not be used as the only imaging modality as it failed to detect CT-positive, active tumor regions in some cases.

Low-dose radiation is sufficient for the noninvolved extended-field treatment in favorable early-stage Hodgkin's disease: long-term results of a randomized trial of radiotherapy alone.

PURPOSE To show that radiotherapy (RT) dose to the noninvolved extended field (EF) can be reduced without loss of efficacy in patients with early-stage Hodgkins disease (HD). PATIENTS AND METHODS During 1988 to 1994, pathologically staged patients with stage I or II disease who were without risk factors (large mediastinal mass, extranodal lesions, massive splenic disease, elevated erythrocyte sedimentation rate, or three or more involved areas) were recruited from various centers. All patients received 40 Gy total fractionated dose to the involved field areas but were randomly assigned to receive either 40 Gy (arm A) or 30 Gy (arm B) total fractionated dose for the clinically noninvolved EF. No chemotherapy was given. RT films were prospectively reviewed for protocol violations and recurrences retrospectively related to the applied RT. RESULTS Of 382 recruited patients, 376 were eligible for randomized comparison, 190 in arm A and 186 in arm B. Complete remission was attained in 98% of patients in each arm. With a median follow-up of 86 months, 7-year relapse-free survival (RFS) rates were 78% (arm A) and 83% (arm B) (P =.093). The upper 95% confidence limit for the possible inferiority of arm B in RFS was 4%. Corresponding overall survival rates were 91% (arm A) and 96% (arm B) (P =.16). The most common causes of death (n = 27) were cardiorespiratory disease/pulmonary embolisms (seven), second malignancy (six), and HD (five). Protocol violation was associated with significantly poorer RFS. Nonirradiated nodes were involved in 42 of 52 reviewed relapses, infield areas in 18, marginal areas in 17, and extranodal sites in 16. CONCLUSION EF-RT alone attains good survival rates in favorable early-stage HD. The 30-Gy dose is adequate for clinically noninvolved areas. Protocol violation worsens the subsequent prognosis. Relapse patterns suggest that systemic therapy can reduce the 20% long-term relapse rate.

14-Day Variant of the Bleomycin, Etoposide, Doxorubicin, Cyclophosphamide, Vincristine, Procarbazine, and Prednisone Regimen in Advanced-Stage Hodgkin’s Lymphoma: Results of a Pilot Study of the German Hodgkin’s Lymphoma Study Group

PURPOSE This multicenter pilot study assessed the feasibility and efficacy of a time-intensified bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone (BEACOPP) regimen given in 14-day intervals (BEACOPP-14) with granulocyte colony-stimulating factor (G-CSF) support in advanced Hodgkins lymphoma. PATIENTS AND METHODS From July 1997 until March 2000, 94 patients with Hodgkins lymphoma stage IIB, III, and IV were scheduled to receive eight cycles of BEACOPP-14. Consolidation radiotherapy was administered to regions with initial bulky disease or residual tumor after chemotherapy. RESULTS All patients were assessable for toxicity and treatment outcome. Eighty-six patients received the planned eight cycles of BEACOPP-14. Consolidation radiotherapy was given in 66 patients. Chemotherapy could generally be administered on schedule. Dose reductions varied among drugs but were generally low. Acute toxicity was moderate, with World Health Organization grade 3/4 leukopenia in 75%, thrombocytopenia in 23%, anemia in 65%, and infection in 12% of patients. A total of 88 patients (94%) achieved a complete remission. Four patients had progressive disease. At a median observation time of 34 months, five patients have relapsed, one patient developed a secondary non-Hodgkins lymphoma, and three deaths were documented. The overall survival and freedom from treatment failure rates at 34 months were 97% (95% confidence interval [CI], 93% to 100%) and 90% (95% CI, 84% to 97%), respectively. CONCLUSION Acceleration of the BEACOPP baseline regimen by shortening cycle duration with G-CSF support is feasible and effective with moderate acute toxicity. On the basis of these results, the German Hodgkins Lymphoma Study Group will compare the BEACOPP-14 regimen with BEACOPP-21 escalated in a prospective multicenter randomized trial.

Outcome of Patients Experiencing Progression or Relapse After Primary Treatment With Two Cycles of Chemotherapy and Radiotherapy for Early-Stage Favorable Hodgkin's Lymphoma

PURPOSE To evaluate treatment outcome of patients with early-stage favorable Hodgkins lymphoma (HL) who experience disease relapse after primary treatment with two cycles of chemotherapy followed by radiotherapy (RT). PATIENTS AND METHODS Of 1,129 patients with early-stage favorable HL enrolled onto the HD7/HD10/HD13 trials of the German Hodgkin Study Group, 42 patients were identified with treatment failure, of whom eight had primary progressive disease, seven had early relapse (< or = 12 months), and 27 had late relapse (> 12 months). We analyzed this group of patients for risk factors, salvage therapy, and treatment outcome. RESULTS The median age was 41 years (range, 19 to 72 years); 24 patients were male, 15 patients had outfield relapse, 13 patients infield relapse, and nine patients outfield and infield relapse. At relapse, 24 patients were treated with conventional salvage chemotherapy, 14 patients were treated with high-dose chemotherapy followed by autologous stem-cell transplantation, and four patients were treated with RT alone. At 36 months median follow-up, freedom from second treatment failure (FF2F) and overall survival (OS) were 52% and 67%, respectively. According to the prognostic score for relapsed HL (duration of first remission, clinical stage, and anemia at relapse), patients with two or three poor prognostic features had a significantly worse outcome compared with patients with none or one of these factors (P < .05 for FF2F and OS). CONCLUSION Relapse after primary treatment with two cycles of doxorubicin, bleomycin, vinblastine, and dacarbazine followed by RT is rare. In our analysis, results were influenced by a high treatment-related mortality rate. Additional studies are needed to define the optimal salvage therapy.

Non-Hodgkin’s Lymphoma After Primary Hodgkin’s Disease in the German Hodgkin’s Lymphoma Study Group: Incidence, Treatment, and Prognosis

PURPOSE The cumulative incidence for non-Hodgkin lymphomas (NHL) after primary Hodgkins disease (HD) ranges between 1% and 6%. To investigate the course of disease for secondary NHL, we retrospectively analyzed patients treated within clinical trials of the German Hodgkins Lymphoma Study Group (GHSG) since 1981. PATIENTS AND METHODS From 1981 to 1998, the GHSG conducted three generations of clinical trials for the treatment of primary HD involving a total of 5,406 patients. Reference histology by an expert panel was obtained for 4,104 of the patients. Data on incidence, treatment, and outcome of secondary NHL were updated in March 1999. RESULTS At first diagnosis of HD, the pathologists rejected 114 (2.1%) of 5,520 cases initially diagnosed as HD and rediagnosed them as primary NHL. Fifty-two (0.9%) of the remaining 5,406 patients developed a secondary NHL. One patient was excluded from further analyses because of insufficient documentation. Six patients had no further therapy because of patient refusal (n = 1) or rapidly progressive disease (n = 5). For the remaining 45 patients, overall response rate was 43% (36% complete response and 7% partial response). The actuarial 2-year freedom from treatment failure (FFTF) and overall survival (OS) for all patients was 24% and 30%, respectively, and for patients with diffuse large-cell lymphoma, it was 28% and 35%, respectively. Time of occurrence of secondary NHL after first diagnosis of HD and variables employed in the age-adjusted International Prognostic Factor Index (IPFI) significantly influenced treatment outcome. CONCLUSION In the GHSG, the incidence of secondary NHL with 0.9% is relatively low compared with previously reported series. The prognosis of secondary NHL seems dismal and is significantly influenced by time of occurrence and the age-adjusted IPFI. In a subset of patients with secondary NHL, long-term disease-free survival could be achieved.

Therapy-related acute myeloid leukemia and myelodysplastic syndromes in patients with Hodgkin lymphoma: a report from the German Hodgkin Study Group

Therapy-related acute myeloid leukemia and myelodysplastic syndromes (t-AML/MDS) represent severe late effects in patients treated for Hodgkin lymphoma (HL). Because more recent data are scarce, we retrospectively analyzed incidence, outcome, and risk factors for the development of t-AML/MDS after HL. A total of 11,952 patients treated for newly diagnosed HL within German Hodgkin Study Group trials between 1993 and 2009 were considered. At a median follow-up of 72 months, t-AML/MDS was diagnosed in 106/11,952 patients (0.9%). Median time from HL treatment to t-AML/MDS was 31 months. The median age of patients with t-AML/MDS was higher than in the whole patient group (43 vs 34 years, P < .0001). Patients who received 4 or more cycles of BEACOPP(escalated) had an increased risk to develop t-AML/MDS when compared with patients treated with less than 4 cycles of BEACOPP(escalated) or no BEACOPP chemotherapy (1.7% vs 0.7% vs 0.3%, P < .0001). The median overall survival (OS) for all t-AML/MDS patients was 7.2 months. However, t-AML/MDS patients proceeding to allogeneic stem cell transplantation had a significantly better outcome with a median OS not reached after a median follow-up of 41 months (P < .001).
