Combination chemotherapy of Hodgkin's disease with adriamycin, bleomycin, vinblastine, and imidazole carboxamide versus MOPP.

This paper reports the preliminary results of a controlled study randomizing MOPP vs. a new four-drug combination (ABVD) in advanced Hodgkin's disease. ABVD consists of 6 cycles of adriamycin, bleomycin, vinblastine, and imidazole carboxamide. The purpose for designing this new combination was two-fold: to compare the efficacy of ABVD with MOPP, and to demonstrate absence of cross-resistance between the two regimens. Of 60 patients entered into the study, 45 (MOPP25, ABVD20) are presently evaluable for the analysis of remission induction. No patient was previously treated with chemotherapy; 20% had relapsed after primary radiotherapy. Whenever possible, complete remission was defined also through rebiopsy of known organ involvement. Complete remission occurred in 76% of patients treated with MOPP and in 75% of those given ABVD, with no difference between the two regimens as far as stage (IIIB-IIIS and IV), histologic type, and prior irradiation were concerned. Crossover carried out for progressive disease or for relapse after initial remission showed absence of cross-resistance between MOPP and ABVD. Toxic manifestations after ABVD were in general well tolerated and reversible. The percent of optimal dose for each drug was as follows: adriamycin 87%, vinblastine 87%, bleomycin 96%, and imidazole carboxamide 96%. These preliminary results indicate that in terms of complete remission, ABVD could represent a successful alternative to MOPP to be used either in MOPP failures or in sequential combination with MOPP. However, the lack of long-term followup limits at the present time an adequate comparison between the two treatments.
