MOPP/ABV hybrid program: combination chemotherapy based on early introduction of seven effective drugs for advanced Hodgkin's disease.

Seventy patients with advanced Hodgkin's disease, 54 with new disease, and 16 in first relapse after initial radiotherapy, have been treated with a seven-drug, 8-month program: MOPP (nitrogen mustard, vincristine, procarbazine, prednisone)/ABV (Adriamycin [Adria Laboratories of Canada, Mississauga, Ontario], bleomycin, vinblastine) hybrid. A single involved field of radiotherapy was given to selected partial responders after 6 months of chemotherapy. Forty-six of the 52 (88%) evaluable new-disease patients and 14 of the 16 (87%) evaluable patients with relapsing disease reached a complete response. The actuarial overall survival at 49 months for the patients with new disease was 90% (median follow-up from diagnosis was 27 months). For the patients with relapsing disease, the actuarial survival at 54 months was 79% (median follow-up from diagnosis was 27 months). The actuarial relapse-free survival at 41 months for complete responders was 93% for patients with new disease (median follow-up after treatment was 20 months) and 80% for those with relapsing disease (median follow-up after treatment was 27 months). Toxicity was moderate, with two treatment-related deaths and eight episodes of serious infection. These results compare favorably with the best results reported in the literature. Furthermore, they were achieved with a moderate level of toxicity, high drug delivery rates, and a relatively short duration of treatment. The efficacy and toxicity data of the MOPP/ABV hybrid program will now be evaluated in a prospectively randomized multicenter study.
