[Effect of different regimens of chemotherapy and x-ray irradiation on the kinetics of experimental tumor growth].

Studies on the effect of different regimens of chemotherapy and local x-ray irradiation on the kinetics of the growth of Walker carcinosarcoma and Heren carcinoma have demonstrated that in the range of dosage of alkylating action drugs under study and also irradiation, the time of the recurrence onset depends on the therapeutic regimen. In cases when tumor regression is gained, the rate of the regression is not dependent on single doses of the drug or irradiation.
