ObjectivesTo investigate the association of tumor location on oncological outcomes in patients treated with radical nephroureterectomy (RNU) for primary ureteral urothelial carcinoma (UC).Materials and methodsFrom January 1990 to December 2007, 127 patients with primary solitary ureteral UC who underwent RNU at our institution were included. The patients were divided into 3 groups based on tumor location—proximal, middle, or distal ureter. Patients' medical records were reviewed retrospectively. The clinicopathologic data and oncologic outcomes were compared among the groups.ResultsOf the 127 patients, 40 (31.5%) had tumors in the proximal ureter, 40 (31.5%) in the middle ureter, and 47 (37.0%) in the distal ureter. Patients with distal ureteral UC were more likely to undergo open procedures to manage the bladder cuff (P = 0.005). Other clinical and histopathologic variables were not different among the 3 groups. Comparing the proximal, middle, or distal ureteral UC, bladder recurrence developed in, respectively, 25.0%, 25.0%, and 21.3% cases (P = 0.892); local retroperitoneal recurrence in 2.5%, 12.5%, and 4.3% (P = 0.141); contralateral recurrence in 0%, 0%, and 4.3%(P = 0.177); and distant metastasis in 17.5%, 10.0%, and 4.3% (P = 0.147). Recurrence-free and cancer-specific survival among the 3 groups were not different (P = 0.781 and 0.192, respectively).ConclusionsTumor location cannot be used to predict oncologic outcomes in patients treated with RNU for primary ureteral UC. Therefore, clinical decisions or follow-up protocol should not differ among patients with primary proximal, middle, or distal ureteral UC.
