Incidence and survival patterns of clear cell renal cell carcinoma from 2000 to 2017: A SEER Database Analysis.

Abstract

Background: Clear cell renal cell carcinoma (ccRCC) incidence and death have considerably changed in recent years. Our study aimed to investigate the incidence, survival, and tumor characteristics of ccRCC in the year of diagnosis. Methods: Our study participants were selected from the SEER database (2000-2017). Age-standardized incidence rates were calculated to compare incidence rates across time. In addition, we used Kaplan-Meier curves to calculate overall survival (OS) and Cox proportional hazards models to explore risk factors associated with mortality outcomes in patients with ccRCC. Results: In the SEER analysis from 2000 to 2017, the increasing trend in age-adjusted incidence of ccRCC has remained relatively stable over the years, increasing from 2.63 per 100,000 in 2000 to 8.79 per 100,000 in 2017. The increase in the incidence of patients at a localized stage plays a decisive role in the overall increase in the incidence of ccRCC. Conclusions: In the general population, patients diagnosed between 2009-2017 had a higher survival rate than those diagnosed between 2000-2008, which is consistent with all stages of the tumor. The incidence of ccRCC increases steadily with the year of diagnosis, while overall survival has significantly improved.
