Experimental basis and clinical experience with non-cross-resistant combinations in solid tumours

Experimental studies on anticancer drug resistance have shown that cisplatin and alkylating agents have a very low level of cross resistance towards heterocyclic agents such as anthracyclines, podophyllotoxins and vinca alkaloids. Based on this and on the model of Goldie and Coldman protocols using sequentially alternating non-cross-resistant combinations were given in testicular cancer, sarcomas and small cell bronchogenic carcinomas. Preliminary clinical results are presented here.
