[Phase II study of cis-diamminedichloroplatinum (II) in genitourinary cancer].

One hundred and twelve patients with evaluable genitourinary tumors were treated with cis-diamminedichloroplatinum (II) as a single agent under multi-institutional clinical trials. Most patients had extensive prior therapy. Of 30 patients with testicular tumors, 5 complete responses (16.7%) and 15 partial responses (50.0%), of 29 patients with bladder carcinoma, 2 CR (6.9%) and 7 PR (24.1%), of 34 patients with prostatic carcinoma, 6 PR (17.6%), and of 10 patients with pelvis and ureter carcinoma, 1 CR and 3 PR were obtained respectively. No responder was seen in eight patients with renal cell carcinoma and in one with urethral carcinoma. Adverse reactions were similar to those already reported including gastrointestinal reactions, nephrotoxicity and myelosuppression. Ototoxicity, peripheral neuropathies and transient elevation of GOT-GPT levels were occasionally encountered. Cis-diamminedichloroplatinum (II) appears to be highly active as a single agent in the treatment of advanced genitourinary tumors.
