Background: The present study was conducted to examine the natural history of superficial bladder cancer.

Methods: One hundred and forty-four patients with superficial bladder cancer who had been treated with transurethral resection of bladder tumor (TURBt) alone were analyzed.

Results: The non-recurrence rate was 64.8% at 36 months and 61.2% at 60 months after TURBt. When the non-recurrence rate after TURBt was analyzed by background variables, the rate differed significantly between the solitary tumor group and the multiple tumor group. The tumor recurrence hazard curves for the entire population had one high peak before 500 days and another slight peak around 1500 days after TURBt.

Conclusions: These results will provide basic information useful when evaluating new regimens of intravesical instillation therapy for prophylaxis of superficial bladder cancer after our complete TURBt in the Nara Uro-Oncology Research Group.
