[Effectiveness of nitrosomethylurea derivatives in the combined chemotherapy of experimental tumors].
An antitumour activity of combined application of two nitrosomethylurea derivatives--dimethylnitrosourea and ADEKO with cytostatics of various groups was studied in transplanted tumours of La and L 1210 leukemias and Lewis lung carcinoma. A combined treatment by ADEKO with cyclophosphamide, methotrexate and dibunol resulted in therapeutic synergism evaluated by the tumour growth inhibition activity (kappa *) and by life span (delta tau) increase of tumour-bearing animals. An additive antitumour effect was established in case of a combined application of ADEKO with ftorafur, vincristine, prednisolone and dimethylnitrosourea with methotrexate.
