Abstract

Objectives: To investigate the association of tumor location on oncological outcomes in patients treated with radical nephroureterectomy (RNU) for primary ureteral urothelial carcinoma (UC). Materials and methods: From 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. Results: Of 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). Conclusions: Tumor 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.
