title: Initial intravenous cis-platinum therapy: improved management for invasive high risk bladder cancer?
abstract: Between August 1981 and December 1983, 50 patients with invasive high risk bladder cancer were treated initially with 100 mg. per m.2 cis-platinum intravenously in 2 doses with a 3-week interval, which was followed by definitive treatment (radiotherapy and/or cystectomy). High risk disease was defined on the basis of at least 2 of the following: invasion into or beyond the muscle (stages B2 to D1), grade III histology, large tumors and ureteral obstruction. Major symptomatic improvement was noted in 38 patients (76 per cent) after 1 to 2 doses of cis-platinum and 30 (60 per cent) had an objective response to cis-platinum. An objective response (complete or partial remission) was noted in 43 patients (86 per cent) after cis-platinum plus definitive treatment. The 12-month actuarial survival was 86 per cent and the 2-year actuarial survival was 80 per cent (although only 14 patients were entered in the study more than 2 years ago). The protocol was well tolerated, with nausea and vomiting being the most common side effects. There were no deaths related to treatment. Ten patients (20 per cent) died of cancer. The relevance of initial cis-platinum therapy in this management program is now being evaluated in a multicenter randomized trial.
