Thirty-six previously treated adult patients with advanced soft tissue sarcomas received CPDD 120 mg/m2 with mannitol diuresis. There were only two (6%) partial responses and five (15%) minor responses in 34 evaluable patients. Toxicity included nausea and vomiting, myelosuppression, mild ototoxicity and mild to moderate, transient nephrotoxicity. CPDD has minimal antitumor activity in previously treated patients with soft tissue sarcomas.
