257 Background: Urothelial carcinoma involving the upper tract (UTUC) accounts for only 5% of urothelial malignancies; thus the majority of data are from single institution series or highly selected patient populations. We sought to examine contemporary trends in overall (OS) and disease-specific survival (DSS) for UTUC using a large, population based dataset. Methods: Patients within the Surveillance, Epidemiology, and End Results (SEER) database with de novo UTUC from 1973-2008 were included and analyzed in 5 year increments to evaluate disease trends. Univariate and multivariate for OS and DSS competing risks analysis were performed adjusting for age, gender, and race for renal pelvis and ureteral tumors. Results: A total of 14,237 patients met inclusion criteria. For renal pelvis tumors (n=9,318), overall survival was 54.4% at 3 years. On multivariate analysis factors that were significant predictors of OS were: age (HR 1.03, p<0.001), and year of diagnosis (HR 1.32, p<0.001). Competing risks regression estimated DSS of 60.5% at 5 years, with male gender, black race, and year of diagnosis remaining significant after adjusting for covariates (p<0.05). For ureteral tumors (n=4,919), overall survival was 56.1% at 3 years. On multivariate analysis, age was a significant predictor of OS (2.73, 95%CI 2.52-2.93, p<0.001). Competing risks regression estimated DSS of 61.9% at 5 years, with female race, and year of diagnosis remaining significant after adjusting for covariates (p<0.05). For both renal pelvis and ureteral tumors, the more contemporary era (1997-2002, 2003-2008) showed worse survival than prior eras (p<0.05). Conclusions: Disease-specific survival for patients with renal pelvis and ureteral UTUC appears to be worse in the contemporary era. While sociodemographic factors (age, gender, and race) appear to impact prognosis, it is unclear what factors may be contributing to this decline. This data adds to the growing literature supporting a paradigm change in the treatment of this disease.
