Popis: Purpose: The purpose of this study is to describe the epidemiological profile, histopathological features, and outcomes of patients diagnosed with renal cell carcinoma (RCC) in a tertiary referral center over 10 years. Methodology: This is a retrospective cohort of 219 Saudi patients diagnosed with RCC between June 2003 and May 2013. The variables collected included the sociodemographic details and clinical presentation. The histopathological features investigated include the tumors histological subtype, pathologic staging tumor, node, and metastasis descriptors, and lymph-vascular invasion. Patients were followed until May 2013. Bivariable analysis was calculated using Chi-square test, with level of significance set at P < 0.05. Kaplan–Meier estimate was used to calculate the survival rate. Results: The mean age of patients was 57.18 (±14.68 standard deviation). The trend of patients diagnosed with RCC over the past 10 years was higher among males than females (60.27% vs. 39.73%). Noticeably, more than half (57.58%) were diagnosed incidentally. The most common histological subtype was clear cell (conventional) RCC (70.44%). Patients were usually diagnosed at the pT1 stage (48.1%). The histopathological features associated with worse patient outcome were the stage of the primary tumor (P = 0.01) and lymph-vascular invasion (P = 0.003). The overall mean survival rate was 2.03 years. Conclusion: In the past 10 years, there are more patients diagnosed incidentally with RCC, which is in line with the global trend. Patients were more likely to be male and middle aged. We recommend further population-based studies in this area to establish a national epidemiological data for this common type of cancer.
