Abstract
Purpose: We wanted to identify the predictive factors of pathologic over- staging in a homogeneous series of patients who had undergone radical cystectomy for their clinical T2 stage bladder cancer.

Materials & Methods: We retrospectively analyzed the clinicopathological parameter of 53 patients who had undergone radical cystectomy for the management of muscle-invasive transitional cell carcinoma. Of these 53 patients, 44 were men and 9 were women. The mean age was 61.3 years. After dividing the entire cohort into 2 groups according to final pathologic stage(¡ÃpT3 and ¡ÂpT2), we compared the clinicopathological parameters such as the time interval between the initial diagnosis of muscle invasion and cystectomy, the number of transurethral resection of bladder tumors(TURBTs), intravesical immunochemotherapy, the tumor grade, the p53 expression, the presence of carcinoma in situ and the gross findings of transurethral resection of bladder tumor(i.e. tumor size, multiplicity and tumor configuration) between the 2 groups.

Results: The final pathologic stages were ¡ÂpT2 in 31 patients(58.5%), pT3 in 20 patients(37.7%) and pT4 in 2 patients(3.8%). Comparison of the clinical staging with the pathological staging revealed that 22 of the 53 cases(41.5%) were clinically understaged. There were no statistically significant differences between the ¡ÃpT3 and ¡ÂpT2 groups regarding the number of TURBTs, intravesical immunochemotheraphy, tumor grade, the p53 expression, the presence of carcinoma in situ and the gross findings of TURBT. But patients with a time interval of ¡Ã2 months between the diagnosis of muscle invasion and cystectomy had a significantly higher frequency of extravesical disease.

Conclusion: These results underline the need for early treatment with cystectomy, within a 2 month period, once the diagnosis of muscle invasion has been made. (Korean J Urol 2007;48:390-395)
