Aim: To evaluate the impact of socioeconomic factors (SEFs) on survival of renal cell carcinoma (RCC) patients. Materials & methods: RCC patients diagnosed between 2007 and 2015 were collected from the SEER database. The crude and multivariate Cox regression analysis was used to identify the independent prognostic factors and quantity the mortality risks for overall survival (OS). Results: Three SEFs including marital status, insurance status and median household income were identified as prognostic factors for OS. SEF-stage was built based on the three SEFs. Moreover, the SEF-stage 1 had superior OS than SEF-stage 2 within the respective American Joint Committee on Cancer stages. Conclusion: The SEF-stage was an independently prognostic factor for OS in RCC. Incorporation of SEF-stage into the American Joint Committee on Cancer staging system might be beneficial for better survival prediction and clinical management. However, further studies were needed to validate these findings in other populations.
