Objectives: The cystoscopic follow-up of superficial bladder cancer accounts for a considerable workload for urologists and is also an invasive procedure with high costs. There is a potential benefit both to the urologist and the patient if unnecessary cystoscopies can be avoided. Methods: The recurrence and progression rates of 120 patients with pTa G1 or G2 and small (<4 cm) transitional cell carcinoma were evaluated retrospectively. Results: The recurrence rate was 6.5% (8/120) at 3 months. The recurrence rates at 6 and 9 months were 6.7 (8/119) and 3.6% (4/112), respectively. However, when the third month (first check) was clear, the recurrence rates at 6- and 9-month cystoscopy were 4.3 (5/116) and 2.7% (3/111), respectively. The recurrence rate at 12 months was 8% (8/99), For G1 tumors, the recurrence rates at 3, 6, 9 and 12 months were 6 (5/84), 5 (5/83), 2.5 (2/80) and 7% (5/71), respectively. The same results for G2 tumors were 8 (3/36), 8 (3/36), 6 (2/32) and 10.5% (3/28), respectively. The progression rate for the first year was lower than 1%. The difference between G1 and G2 tumors according to recurrence rate within the first year was not statistically significant (p>0.05). Conclusions: This study supports the proposal that for patients with small and welldifferentiated pTa tumors at diagnosis, if the first control cystoscopy is clear, it is appropriate to perform the second check cystoscopy 1 year from initial resection and subsequent controls yearly. One should note that the study group included the most suitable patients for cystoscopic follow-up according to size and multiplicity of the tumor. This change in policy is further supported by the fact that progression occured in less than 1% in this group of patients. Copyright (C) 2000 S. Karger. AG. Basel.
