Abstract:
PURPOSE: To evaluate factors related to the recurrence of TCC(transitional cell carcinoma) in the urinarybladder after transurethral resection of bladder tumor(TUR-BT). MATERIALS AND METHODS: We retrospectivelyreviewed 54 patients in whom TCC(transitional cell carcinoma) after TUR-BT had been confirmed. Recurrence wasevaluated by US, CT, cystoscopy and urine smear during the follow-up period of 6 months. The multiplicity, shape,size, and calcification of TCC, as revealed by radiologic studies, were evaluated retrospectively before TUR-BT.After TUR-BT, the histologic grade and pathologic stage of TCC were evaluated. RESULTS: According to themultiplicity of TCC, the recurrence rate was 66.7% in the multiple type and 28.6% in the single type(p=0.039) ;according to shape, this rate was 61.5% in the sessile type and 29.3% in the pedunculated type(p=0.0505), andaccording to mass size, the rate was 41.7% in tumors more than 3cm in diameter and 35.7% in tumors less than3cm(p=0.706). In the presence of calcification, the recurrence rate was 40.0% and in its absence, this rate was36.7%(p=0.885). Pathologically, the higher the grade and stage of TCC, the higher the recurrence rate(respectivelyp=0.010 and 0.041). CONCLUSIONS: Radiologically, multiple and/or sessile type TCC had a higher recurrence ratethan the single and/or pedunculated type. Pathologically, when the grade and stage of bladder tumor were higher,recurrence rates were higher.
