OBJECTIVES: To retrospectively assess the significance of gender as a predictor of intravesical recurrence following nephroureterectomy for urothelial carcinoma of the upper urinary tract (UC-UUT). MATERIALS AND METHODS: This study included 502 consecutive patients (360 male and 142 female) who were diagnosed as having clinically localized UC-UUT and underwent nephroureterectomy. Clinicopathologic outcomes of these patients were analyzed focusing on the impact of gender. RESULTS: The incidence of intravesical recurrence in male patients (41.9%) was significantly greater than that in female patients (27.5%). Despite the lack of significant differences in cancer-specific and overall survivals with respect to gender, the intravesical recurrence-free survival in male patients was significantly worse than that in female patients. Of several parameters examined, univariate analysis identified gender, tumor site, and tumor focality as significant predictors of intravesical recurrence following nephroureterectomy. Of these, only gender and tumor site appeared to be independently associated with intravesical recurrence-free survival on multivariate analysis. Furthermore, there was a significant difference in intravesical recurrence-free survival according to positive numbers of these two independent factors; that is, intravesical recurrence occurred in 12 of 55 patients who were negative for both risk factors (21.8%), 96 of 280 positive for a single risk factor (34.3%), and 82 of 167 positive for both risk factors (49.1%). CONCLUSIONS: The incidence of intravesical recurrence following nephroureterectomy for UC-UUT is comparatively high. Therefore, it would be potentially important to perform careful follow-up targeting intravesical recurrence for such patients, particularly for male patients and/or patients with tumor located at the ureter.
