Progress in the chemotherapy of hematologic diseases.

Progress in the chemotherapy of Hodgkin's disease and experimental therapeutic, pharmacologic, and clinical studies of the antitumor antibiotic, adriamycin, are presented in this abstract. In patients with disseminated Hodgkin's disease, the combination chemotherapy program (MOPP) produces a significant increase in the complete remission rate. This has been increased to 90% by the addition of low dose bleomycin to the MOPP program. The continuation of MOPP treatment beyond 6 months and to a total of 24 months provides improved results in patients in remission as measured either from time of onset of complete remission or from end of treatment. Finally, the pattern of relapse in patients with Hodgkin's disease provides a rationale basis for the selective use of radiotherapy in patients in complete remission. Adriamycin has a broad spectrum of antitumor activity in man. Its mechanism of action involves intercalation with DNA and inhibition of DNA function. The selective effect against tumors is not understood but may relate to membrane transport. Adriamycin is a highly important new antitumor agent for the treatment, not only of hematologic malignancies, but for a variety of solid tumors as well.
