Will BEACOPP be the standard for high risk Hodgkin lymphoma patients in advanced stages?

Hodgkin Lymphoma (HL) has become one of the most curable cancers, even in adulthood, through continuous improvement of therapeutic options and their verification by large multicenter trials. Today more than 95% of patients with HL in early stages and in advanced stages 85-90% can be cured. Nevertheless, these good results are threatened by treatment associated toxicities such as infertility, cardiopulmonary toxicity and secondary malignancies. It is therefore the aim of future trial generations both to maintain the excellent treatment results and to minimize late effects. In 1964 for the first time deVita et al. described the MOPP polychempotherapy for patients with advanced HL which led to cure rates in more than 50%. Around ten years later Bonadonna et al. established the non cross resistant alternative regime to MOPP, ABVD which nowadays is accepted as "gold standard" for the treatment of advanced HL. MOPP and/or ABVD and furthermore the alternating MOPP/ABVD or the MOPP/ABV hybrid with and without the help of consolidative radiation resulted in around 70% long term survival rates, 30-40% of patients experienced tumor progression or relapses within 5 years. This led the German Hodgkin Study Group (GHSG) [Diehl V, Franklin J, Pfreundschuh M, Lathan B, Paulus U, Hasenclever D, et al. Standard and increased-dose BEACOPP chemotherapy compared with COPP-ABVD for advanced Hodgkin's disease. N Engl J Med 2003; 348: 2386-95] to improve the efficacy of COPP/ABVD by time- and dose-intensification, omission of Velban and Dacarbazin and adding Etoposide resulting in the BEACOPP principle. From the initial pilot studies in 1992 three trial generations, HD9, HD12, HD15, have now established this principle as one of the most effective chemotherapy regimen in advanced HL. We certainly hope that it will not last another 20 years to establish the BEACOPP regimen as an attractive curative treatment option for at least the high risk cohorts of HL.

Collaborative study for the establishment of the 2(nd) International Standard for Bleomycin Complex A2/B2.

Organization (WHO) International Standard (IS) for bleomycin complex A2/B2. Eight laboratories from different countries participated. Potencies of the candidate material were estimated by microbiological assays with sensitive micro-organisms. To ensure continuity between consecutive batches, the 1(st) IS for bleomycin complex A2/B2 was used as a reference. Based on the results of the study, the 2(nd) IS for bleomycin complex A2/B2 was adopted at the meeting of the WHO Expert Committee for Biological Standardization (ECBS) in 2014 with an assigned potency of 12 500 International Units (IU) per vial. The 2(nd) IS for bleomycin complex A2/B2 is available from the European Directorate for the Quality of Medicines & HealthCare (EDQM).

Preliminary results of concurrent radiotherapy and chemotherapy with cis-platinum, vincristine, and bleomycin in bulky, advanced cervical carcinoma: a pilot study.

Twenty-four patients with bulky (greater than 4 cm), advanced (stages IIB-IVA) carcinoma of the uterine cervix were prospectively treated with a concurrent combination of radiotherapy (RT) and chemotherapy (CT). RT consisted of 4400 cGy (22 fractions) to the whole pelvis and a 1400-cGy boost to the parametrium. This was followed by two to three intracavitary brachytherapy courses. CT consisted of one to four course (median, three) of cisplatin (50 mg/m2) on Day 1, vincristine (1 mg/m2) on Day 2, and bleomycin (25 mg/m2) on Days 2-4. CT was started on the first day of external radiation and the scheduled course interval was 21 days. Among the 20 evaluable patients who completed at least one course of chemotherapy and a full course of radiation, 13 (65%) achieved complete response and 5 (25%) had partial response. Fatal complication occurred in 1 patient with stationary disease who died of septic shock due to ruptured pyometra. The other patient with primary stage IVA disease had progressive disease with ascites appearance after two courses of CT and later expired. Transient drug fever occurred in 19 (40.4%) of the 47 bleomycin-containing CT cycles. Grade 2 or 3 hematological toxicities occurred in 16 (30.2%) of a total of 53 CT cycles. Treatment delays of 1 to 7 days occurred in 15 (28.3%) CT cycles. Except for the case of septic shock, all of the other toxicities were generally tolerable and reversible. From this preliminary result we concluded that this particular combination of RT and CT in bulky, advanced cervical carcinoma is effective in enhancing local pelvic tumor control and well tolerated if strict selection of accrued patients is applied. Further investigation to assess its impact on long-term survival is in progress.

Etoposide, ifosfamide and methotrexate combination chemotherapy in patients with aggressive non-Hodgkin's lymphoma after failure of the LNH 84 regimen.

We assessed the efficacy of an etoposide, ifosfamide and methotrexate combination therapy (VIM) in 24 patients failing the LNH 84 protocol. Eight of these patients were refractory to the LNH 84 induction regimen, 10 were partial responders and the six remaining attained complete response after LNH 84 induction but relapsed during consolidation therapy or after completing the whole programme. Twenty-three patients were evaluable for response. The VIM regimen provided a 43 per cent complete response rate and an additional 17 per cent partial response rate. The complete response rate was particularly high (67 per cent) in the group of patients who were partial responders to LNH 84 induction treatment. Of the 10 complete responders, five relapsed after 4 to 42 months and five are still alive with no evidence of disease after 27 to 60 months. Overall VIM was well tolerated. Myelotoxicity was the most common side-effect. Infections with fever were observed in 8 per cent of the VIM courses. This study demonstrates that a complete response and a long survival can be obtained in patients after failure of a high-dose doxorubicin containing front-line treatment.

Primary mediastinal large B-cell lymphoma with sclerosis: a clinical study of 89 patients treated with MACOP-B chemotherapy and radiation therapy.

BACKGROUND AND OBJECTIVES: Primary mediastinal large B-cell lymphoma (PMLBCL) with sclerosis has recently been recognized as a specific clinical and pathologic entity for which the best therapeutic approach seems to be a combination of chemotherapy and radiotherapy. DESIGN AND METHODS: Between 1989 and 1998, 89 previously untreated patients with PMLBCL with sclerosis were treated with a combination of a third-generation chemotherapy regimen (MACOP-B) and mediastinal radiation therapy. The response evaluations were examined after chemotherapy and at the end of radiotherapy. RESULTS: Twenty-three (26%) patients achieved a complete response (CR) and 59 (66%) obtained a partial response (PR) after the MACOP-B regimen. After radiation therapy, 55/59 (93%) of the patients in PR achieved CR. The CR rate at the end of the treatment was 88% (78/89). Only 7 (8%) patients were non-responders. Among the 78 patients who obtained a CR there were 7 (9%) relapses in a median follow-up of 5 months (all relapses occurred within 9 months); the other 71 patients are currently in continuous CR with a median follow-upof 45 months (range, 4-110 months). Projected overall survival was 86% at 9 years; the relapse-free survival curve of the 78 patients who achieved CR was 91% at 9 years. INTERPRETATION AND CONCLUSIONS: In patients with PMLBCL with sclerosis, combined modality treatment using the MACOP-B chemotherapy regimen and radiation therapy induces a good remission rate with the patients having a greater than 90% chance of surviving disease-free at 9 years. Radiotherapy often plays a pivotal role in obtaining CR status.

Lomustine and melphalan cannot be replaced by cyclophosphamide and etoposide without reducing efficacy in MOPPEBVCAD chemotherapy for advanced Hodgkin's disease.

BACKGROUND AND OBJECTIVES: To evaluate the feasibility, toxicity and preliminary results of a potentially less toxic variant of the MOPPEBVCAD chemotherapy regimen for advanced Hodgkin's disease: MOPPEBVCyED, in which cyclophosphamide and etoposide replace lomustine and melphalan, respectively, with the remaining components being unaltered. DESIGN AND METHODS: The study was multicenter, prospective and randomized, and enrolled 67 patients with newly diagnosed stage IIB, III, IV Hodgkin's disease (62 were expected on the grounds of statistical considerations). Radiotherapy was restricted to sites of bulky involvement or to areas that responded incompletely to chemotherapy. Median follow-up was 48 months. RESULTS: Comparing MOPPEBVCAD vs. MOPPEBVCyED, the results were as follows: complete remissions 35/35 vs. 30/32 (plus one partial remission and one disease progression); relapses 5 vs. 8; deaths 2 (one of myelodysplasia) vs. 2; delivered mean dose intensity (DI): lomustine 0.79+/-0.67 vs. cyclophosphamide 0.82+/-0.32; melphalan 0.80+/-0.13 vs. etoposide 0.86+/-0.18; average DI of the 7 drugs common to both regimens 0.73+/-0.10 vs. 0.83+/-0.11; all 9 drugs 0.75+/-0.13 vs. 0.84+/-0.09 (p=0.002); projected 5-year failure-free survival 0.79 vs 0.62; second cancers, two myelodysplasias vs. one carcinoma of the kidney. Toxicities were not statistically different except for heavier thrombocytopenia being recorded with MOPPEBVCAD. INTERPRETATION AND CONCLUSIONS: The higher cumulative and single drug DI recorded with MOPPEBVCyED may reflect better short-term tolerability, but it does not lead to better disease control. Its late toxicity may be expected to be lower in the future but at present it does not seem to be a sufficient reason to substitute MOPPEBVCyED for MOPPEBVCAD.
