Abstract
Patients with superficial transitional cell carcinoma of the bladder were entered in a randomized clinical trial to compare the efficacies of transurethral resection alone or followed by bladder instillation of doxorubicin hydrochloride or ethoglucid (Epodyl) for 1 year. Results showed that adjuvant chemotherapy with the selected drugs prolonged the mean interval between recurrences. Mild systemic toxicity and chemical cystitis were observed in 3 and 3 per cent, respectively, of the patients given ethoglucid, and in 5 and 4 per cent, respectively, of those taking doxorubicin.
