A single instillation of epirubicin after transurethral resection of bladder tumors prevents only small recurrences
2008
Purpose: We studied whether a single instillation of epirubicin after transurethral bladder tumor resection would influence the interval to and size of the first recurrence.Materials and Methods: A total of 404 patients from 13 hospitals were randomized to 1 instillation of 50 mg epirubicin or placebo within 6 hours after transurethral resection of bladder tumors.Results: Of 155 evaluable patients in the epirubicin group 79 (51.0%) had recurrence compared to 95 of 152 (62.5%) in the placebo group (p = 0.04). Of the recurrences 63.3% were small (1 to 5 mm). Tumor size was unknown in 5 patients. Of 79 patients with recurrence in the epirubicin arm 33 (42.9%) vs 29 (31.5%) of 95 in the placebo arm had larger (more than 5 mm) first recurrences (p = 0.12). Approximately half of the patients with first recurrences were treated as outpatients and the other half spent a total of 145 days in the hospital with no difference between the groups.Conclusions: We confirmed the results of previous studies showing that 8....
