The authors present a total of 203 patients with histologically proven superficial bladder transitional cell cancer. Patients without recurrence had a follow-up longer than 12 months. The mean follow-up from the time of diagnosis was 35 months +/- 27 (standard deviation). Transurethral resection was not systematically followed by intravesical therapy. The following drugs were used: thiotepa, doxorubicin, BCG and rarely mitomycin C. Although BCG was generally used after failure of thiotepa or doxorubicin, it achieved the best results. 13 patients had a total cystectomy (6.4%). Patients without complete remission had a higher percentage of high grade and stage T1 tumors than patients without recurrence (the difference was statistically significant). The same applied to mortality: it was statistically more frequent in the first group than in the second group of patients.
