[Preoperative chemotherapy of testicular cancer and Wilm's tumor].

Of the various urogenital malignancies, preoperative chemotherapy is most effective for testicular cancer and Wilms' tumor. The most effective treatment regimens for advanced nonseminomatous testicular tumors employ vinblastine, CDDP and bleomycin and adjunctive surgery. Another effective chemotherapy regimen is combination of vinblastine, actinomycin D, bleomycin, cyclophosphamide and CDDP presented by MSKCC. Available pretreatment with 4 courses of platinum, vinblastine and bleomycin before any surgical treatment in those with massive bulk metastatic disease seems to provide the most effective cytoreduction and best survival. Donohue has shown that in a primary chemotherapy group, there is only 20% active carcinoma after primary chemotherapy, whereas in a salvage chemotherapy group there is approximately 50% active carcinoma at surgery. It must therefore be emphasized that complete remission should be obtained by primary chemotherapy and adjunctive surgery. In Wilms' tumor preoperative chemotherapy with vincristine and actinomycin D should be given.
