Crossed chemoprophylaxis assay between adriamycin and cis-platinum in recurrent superficial bladder tumor

Of 146 patients with superficial bladder carcinoma, 66 (35 primary and 31 recurrent from failure of thiotepa chemoprophylaxis) relapsed following transurethral resection (TUR) and chemotherapy with adriamycin or cis-platinum. A new TUR was carried out. In case of progression in the number of tumors, size, stage or grade, treatment was begun with the other drug. If the tumor had the same characteristics, treatment was continued with the same drug. In both the primary and recurrent tumors with or without progression, cis-platinum controlled the tumor better than adriamycin, rescuing it from the latter and obtaining a recurrence index and disease-free interval as with cis-platinum alone. These results are more conclusive in primary tumors.
