A prospective multicenter phase-two study was initiated in 1983 to evaluate the effect of systemic chemotherapy after complete resection of T1 G3–4 and T2 bladder carcinomas. Chemotherapy consisted of three cycles of cisplatin alone, a modified MVAC scheme or the combination of cisplatin and methotrexate. 52 patients entered the study. After a medium follow-up of 36 months 11 patients developed progression of the disease; cystectomy had been performed in 8 patients and 6 patients died due to progressive bladder carcinoma. These encouraging results should be the base for a randomized trial with the aim to improve survival and avoid cystectomy in selected patients with superficially invasive bladder cancer.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
