Intravesical instillation of anti-cancer drug using mainly thio-TEPA has been attempted to prevent reccurrence after conservative therapy on seventy-five cases of superficial bladder tumor diagnosed as papillary tumor. The effect of intravesical instillation in preventing recurrence was studied by comparing the recurrence ratio with that in seventy-three cases of control group treated without instillation. The results were as follows: 1) Recurrence was found in 44 out of 73 cases (60.3%) in the non-instillated group, while in 24 out of 75 cases (32%) in the instillated group. 2) Recurrence was found in 24 out of 44 cases (54.5%) 6 months after the operation and within 2 years over 80% of the cases in the non-instillated group. Recurrence was found in 2 out of 24 cases (8.3%) at 6 months postoperatively and within 3 years about 80% of total cases in the instillated group.
