Abstract

Purpose: While the evidence is clear that patients with carcinoma in situ or high grade T1 TCC of the bladder are at higher risk for developing UUT tumors, the role of imaging the UUT in patients with Ta tumors remains controversial. We hypothesized that the number and frequency of recurrences in patients with Ta disease would allow us to identify a population who should undergo routine UUT surveillance. Materials and Methods: We reviewed our database of 375 patients who underwent resection of a stage Ta TCC between 1975 and 1995. Median followup was 6 years. Patients were stratified according to the presence of an UUT occurrence, rate and timing of superficial recurrences, and grade of the initial bladder tumor. Results: Among the 375 patients 50% had no bladder recurrence, 25% had 1 tumor, 15% had 2 tumors, and 10% had 3 or more tumors. Average time between tumors was 17 months. UUT tumor developed in 13 patients (3.4%) at an average of 22 months after their initial bladder tumor. A high risk group consisting of patients who had 2 or more bladder recurrences recurring within 12 months of each other were at 4.5-fold the risk of UUT tumor. Conclusions: Stage Ta bladder cancer patients with 2 or more recurrences of bladder tumors with a median of less than 12 months between recurrences are at higher risk for developing an UUT tumor and should be considered for more frequent UUT surveillance.
