[Effects of cytostatic agents on proliferative activity and growth of human tumor heterografts in subrenal capsule in mice].

The initial and final proliferative activity (PA) of heterografts of human lung and breast tumors were assayed in cultures grown under the renal capsule in mice with and without cytotoxic drugs. The PA values in the control group proved similar. Chemotherapy-induced changes in PA did not correlate with those in heterograft growth rate.
