422 Background: Since approval of sorafenib in December 2005, several targeted therapeutic agents have been approved by the FDA for the treatment of advanced renal cell carcinoma. This study was conducted to find out whether the improvements in survival of advanced RCC patients with targeted agents have translated into survival benefit in population-based cohort. Methods: We analyzed the Surveillance, Epidemiology, and End Results (SEER) 18 registry database to compare 1- and 3-year relative survival rates among advanced RCC patients during 2001-2009, 2001-2004, and 2006-2009. We also evaluated the survival rates by age (<65 and ≥65 years) and sex. We used SEER*Stat software to analyze the data. Results: The total number of advanced RCC patients during 2001-2009, 2001-2004, and 2006-2009 were 7,055, 3,355 and 2,985 respectively. During 2001-2009, the 1- and 3-year relative survival rates were 26.7± 0.6% and 10.0±0.4% respectively. The 1-year relative survival rates during 2001-2004 and 2006-2009 were 27.0±0.8% and 27.1±0.9%, (p value=1.3) respectively. Similarly, the 3-year survival rates during 2001-2004 and 2006-2009 were 10.1±0.6% and 9.6±0.8%, (p value=1.42), respectively. There was no significant difference in survival rates during 2001-2004 and 2006-2009 periods by age and sex. Conclusions: This population based study showed that there was no significant improvement in relative survival rates among advanced RCC patients in the era of targeted agents. As with other database analyses, limitations of this large study may be incomplete reporting practices and lack of data on treatment.
