title: [A phase II clinical study of cis-diammine glycolato platinum, 254-S, for cervical cancer of the uterus].
abstract: A phase II clinical study of 254-S, a new anticancer platinum complex, for cervical cancer was conducted by the 254-S Cervical Cancer Study Group consisting of 10 institutions. 254-S was administered at 80 mg/m2 by intravenous drip infusion and this administration was repeated at least 2 times at 4-week intervals, in principle. Forty of 45 patients registered, were eligible and 38 were evaluable for tumor response (complete cases). Complete response (CR) and partial response (PR) were obtained in 4 (10.5%) and 9 patients (23.7%), respectively, for a 34.2% response rate. Against squamous cell carcinoma, a 38.2% response rate (4 CR and 9 PR in 34 patients) was obtained. The response rate obtained in patients with no prior chemotherapy was 40.0% (2 CR and 8 PR in 25 patients), while that in patients with prior chemotherapy was 23.1% (2 CR and 1 PR in 13 patients). Major toxic effects observed were hematotoxicity, including thrombocytopenia (35.1%), leukopenia (73.0%), anemia (75.7%), gastrointestinal toxicity such as nausea and vomiting (83.8%) and anorexia (83.8%). Nephrotoxicity observed was in the form of an elevation of serum creatinine with an incidence of 2.7% and a decrease in creatinine clearance with an incidence of 21.7%. In comparison with the results obtained in the phase II clinical study for gynecological cancers in which 254-S was administered at 100 mg/m2, the response rate obtained in this study was slightly lower but thrombocytopenia and leukopenia observed were less frequent and milder. Based on these results, it was concluded that 254-S is a very useful anticancer agent for the treatment of cervical cancer.
