title: [A phase II clinical study of cis-diammine glycolato platinum, 254-S, for advanced breast cancer].
abstract: A phase II clinical study of 254-S, a new anticancer platinum complex for advanced breast cancer, was conducted by the 254-S Breast Cancer Study Group consisting of 6 institutions nation-wide. Considering the results of the phase I clinical study, 254-S was administered at 100 mg/m2 by intravenous drip infusion and this administration was repeated at least 2 times at 4-week intervals. Of 19 patients registered, 16 were evaluable for tumor response (complete cases). Partial response (PR) was obtained in 2 patients, for a 12.5% response rate. Major toxic effects observed were hematotoxicity thrombocytopenia and leukopenia, and gastrointestinal toxicity (nausea and vomiting, and anorexia), though there was no case in which the treatment with 254-S had to be discontinued due to the toxic effect.
