title: Sensitivity to chemotherapeutic and immunomodulating agents of two mouse lymphomas and of a macrophage tumor.
abstract: The effect of treatment with 15 chemotherapeutic and 10 immunomodulating agents on the growth of T-cell lymphoma EL-4, macrophage tumor J774, and B-cell lymphoma 70Z/2 of the mouse has been studied using the prolongation of median survival time of tumor-bearing hosts as an index of therapeutic effectiveness. The survival time of mice bearing 70Z/2 was prolonged more than 100% by single-agent therapy with actinomycin D, cyclophosphamide, 6-mercaptopurine, mitomycin C, and vinblastine; a similar response of J774 was produced by therapy with Adriamycin, cyclophosphamide, or 6-mercaptopurine. No chemotherapeutic agent prolonged the median survival time of mice bearing EL-4 by 100% or more. Of the immunomodulating agents, mycobacterial preparations (Bacillus Calmette-Guérin or interphase material), Corynebacterium parvum, and polyinosinic-polycytidylic acid moderately prolonged the survival time of mice bearing J774 or 70Z/2; the EL-4 lymphoma was refractory to all 10 immunomodulating agents.
