BACKGROUND High-dose chemotherapy followed by transplantation of autologous haemopoietic stem cells (BEAM-HSCT) is frequently used to treat patients with relapsed Hodgkins 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 Hodgkins 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 Hodgkins disease irrespective of length of initial remission.

PURPOSE To investigate whether radiotherapy can be reduced without loss of efficacy from extended field (EF) to involved field (IF) after four cycles of chemotherapy. PATIENTS AND METHODS Between 1993 and 1998, patients with newly diagnosed early-stage unfavorable HD were enrolled onto this multicenter study. Patients were randomly assigned to receive cyclophosphamide, vincristine, procarbazine, and prednisone (COPP) + doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) for two cycles followed by radiotherapy of 30 Gy EF + 10 Gy to bulky disease (arm A) or 30 Gy IF + 10 Gy to bulky disease (arm B). RESULTS Of 1,204 patients randomly assigned to treatment, 1,064 patients were informative and eligible for the arm comparison (532 patients in arm A; 532 patients in arm B). The median observation time was 54 months. Five years after random assignment, the overall survival (OSran) for all eligible patients was 91% and freedom from treatment failure (FFTFran) was 83%. Survival rates at 5 years after start of radiotherapy revealed no differences for arms A and B, respectively, in terms of FFTF (85.8% and 84.2%) and OS at 5 years (90.8% and 92.4%). There also were no differences between arms A and B, respectively, in terms of complete remission (98.5% and 97.2%), progressive disease (0.8% and 1.9%), relapse (6.4% and 7.7%), death (8.1% and 6.4%), and secondary neoplasia (4.5% and 2.8%). In contrast, acute side effects including leukopenia, thrombocytopenia, nausea, gastrointestinal toxicity, and pharyngeal toxicity were more frequent in the EF arm. CONCLUSION Radiotherapy volume size reduction from EF to IF after COPP + ABVD chemotherapy for two cycles produces similar results and less toxicity in patients with early-stage unfavorable HD.

PURPOSE The HD9 trial aims to evaluate whether moderate dose escalation and/or acceleration of standard polychemotherapy is beneficial for advanced-stage Hodgkins disease (HD). Two variants of a novel bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone (BEACOPP) scheme (standard and escalated dose) are compared with cyclophosphamide, vincristine, procarbazine, and prednisone (COPP)/doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD). PATIENTS AND METHODS The randomized, three-arm trial recruited patients in stages IIB and IIIA with risk factors and stages IIIB and IV. BEACOPP in baseline dose contains all drug dosages of COPP/ABVD (except vincristine and procarbazine) rearranged in a shorter, 3-week cycle. Escalated BEACOPP uses higher doses of cyclophosphamide, doxorubicin, and etoposide with granulocyte colony-stimulating factor (G-CSF) support. After eight chemotherapy cycles, initial bulky and residual disease is irradiated. The trial is monitored and analyzed by means of a sequential strategy. RESULTS An interim analysis with 505 assessable patients and a median follow-up of 23 months showed a significant inferiority (according to sequential monitoring strategy) of the COPP/ABVD regimen in progression rate and freedom from treatment failure (FFTF) compared with the pooled results of both BEACOPP variants. The 24-month FFTF rate was 75% for COPP/ABVD and 84% for BEACOPP pooled (P = .034). There was 12% progressive disease with COPP/ABVD and 6% with BEACOPP pooled. Differences in survival were not significant in sequential analysis. The acute toxicity of baseline BEACOPP resembled that of COPP/ABVD; escalated BEACOPP showed increased but manageable hematologic toxicity. CONCLUSION Combined with local irradiation, BEACOPP in one or both variants shows superior disease control compared with COPP/ABVD, with acceptable acute toxicity. Further follow-up is required to assess the effect of dosage and the effect on survival and late toxicities.

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.

UNLABELLED Infertility after treatment of patients with Hodgkins disease (HD) is considered as a side effect of alkylating agent containing chemotherapy regimens. To investigate whether gonadal failure is related primarily to the toxic effect of chemotherapy or rather to the disease itself, we investigated the fertility status before the onset of treatment. PATIENTS AND METHODS Semen quality and hormonal status were evaluated in 158 patients with first diagnosis of HD enrolled into trials of the German Hodgkin Lymphoma Study Group (GHSG). The median age of the patients was 28 years (range 16-52). Twenty patients (13%) were classified as early stage HD, 63 patients (40%) as intermediate stage, and 75 patients (47%)) as advanced stage according GHSG grading. Sixty-seven patients (42%) showed systemic symptoms. Semen analysis was performed according to WHO guidelines. Follicle-stimulating hormone (FSH) and luteinising hormone (LH) plasma levels were measured by specific double-antibody radio-immune-assay (RIA) methods. RESULTS Prior to treatment, severe damage of fertility, i.e.. azoospermia and oligoasthenoteratospermia (OAT-syndrome) was found in 13 (8%) and 20 patients (13%), respectively. Thirty-eight patients (24%) had single, i.e., oligo-(O), astheno-(A) or teratospermia-(T), and 40 patients (26%) showed combined damages, i.e., OA, OT or AT. In 47 patients (30%) a normal sperm count was found. Thus, III patients (70%) showed semen abnormalities before the onset of treatment. In a multivariate analysis elevated ESR (P < 0.003) and advanced stage of disease (P < 0.01) could be distinguished as prognostic factors for severe damage of fertility. No correlation was found between pre-therapeutic gonadotropine levels and fertility status. CONCLUSION Patients with HD have an increased risk for inadequate semen quality even prior to treatment. Infertility is more frequent in patients with elevated ESR and advanced stage of disease. This association demonstrates the predominant influence of the disease on fertility. Assuming HD is the major initial cause for infertility efforts should be made to identify new non-gonadal toxic chemotherapies to be able to regain fertility after effective therapy. Further investigations have to be performed to clarify mechanisms inducing fertility defects in patients with HD.

PURPOSE At present, treatment results for patients with advanced-stage Hodgkins disease remain unsatisfactory. Standard chemotherapy M(C)OPP (nitrogen mustard (cyclophosphamide). vincristine, procabazine, and prednisone). ABVD (adriamycine, bleomycine, vinblastine, and dacarbacine) or M(C)OPP/ABVD +/- radiotherapy fail to achieve long-term complete remission in 35% to 50% of these patients. The BEACOPP (bleomycin, etoposide, adriamycine, cyclophosphamide, vincristine, procarbazine, and prednisone) regimen was developed to improve treatment results by dose intensification achieved by reduced duration of treatment (time intensification) and addition of etoposide. PATIENTS AND METHODS Thirty untreated patients with advanced Hodgkins disease stage IIB IV according to the Ann Arbor classification were treated with the time intensified BEACOPP regimen. Each patient was scheduled to receive eight cycles of chemotherapy with consolidating radiotherapy to sites of initial bulk disease and to residual tumor remaining after chemotherapy. RESULTS All patients were evaluable for assessment of toxicity, treatment response, freedom from treatment failure (FFTF) and survival (SV). Of 30 treated patients, 29 patients received the intended eight cycles of BEACOPP. One patient in clinical CR, terminated the chemotherapy at his own request after six cycles and is at this time, 48 months after the end of treatment, in complete remission. Toxicity was tolerable with WHO grade 3/4 leucopenia in 28% of chemotherapy cycles and one severe (WHO grade 3) infection. No treatment-related death occurred. Cycles could generally be given on schedule. Complete remission (CR) was achieved in all but two patients (93%). At present, only one patient has relapsed. At a median follow-up of 40 months, FFTF-rate is 89% (lower confidence limit: 80%). One patient died due to progressive disease. CONCLUSION The BEACOPP regimen is feasible at moderate hematopoeitic toxicity. With a FFTF-rate of 89% at a median follow-up of 40 months, the treatment results are very encouraging. A prospective randomised trial has been initiated to compare the BEACOPP regimen with the standard COPP/ABVD regimen in advanced-stage Hodgkins disease.

Beykirch; Hartmut Kirchner; Adelheid Emminger; Richard Greil; Esther Fritsch; Peter Koch; Angelika Drochtert; Oana Brosteanu; Dirk Hasenclever; Markus Loeffler; Volker Diehl

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.

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.

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.

P. Anselmo; Volker Diehl

PURPOSE To investigate whether treatment results in intermediate-stage Hodgkins lymphoma can be improved by rapid application of non-cross-resistant drugs, the 10-drug regimen cyclophosphamide, vincristine, procarbazine, and prednisone (COPP), doxorubicin, bleomycin, and vinblastine (ABV), and ifosfamide, methotrexate, etoposide, and prednisone (IMEP), repeated every 6 weeks, was compared with conventional alternating COPP/doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) administered every 8 weeks. PATIENTS AND METHODS From January 1988 to January 1993, 996 patients in stage I or II Hodgkins lymphoma with at least one risk factor (massive mediastinal tumor, massive spleen involvement, extranodal disease, elevated ESR, or more than two lymph node areas involved) and all patients in stage IIIA Hodgkins lymphoma were randomized to receive two cycles of COPP/ABVD or COPP/ABV/IMEP followed by extended-field radiotherapy. RESULTS Both regimens produced similar rates for treatment responses (complete remission, 93% v 94%), freedom from treatment failure (80% v 79%), and overall survival (88% for both regimens) at a median follow-up time of 7 years. Most serious toxicities during chemotherapy were similar in both regimens. However, World Health Organization grade 3 and 4 leukocytopenia occurred significantly more frequently in the COPP/ABV/IMEP arm (53% v 44% of patients; P =.010). There were no differences in the number of serious infections and toxic deaths during therapy. The number of second malignancies was also the same in both arms (22 each). CONCLUSION Alternating COPP/ABVD and rapid alternating COPP/ABV/IMEP in combination with extended-field radiotherapy are equally effective in intermediate-stage Hodgkins lymphoma and produce excellent long-term treatment results.
