Introduction. To evaluate the prognostic outcomes and risk factors for renal cell carcinoma (RCC) patients with venous tumor thrombus in China. Materials and Methods. We reviewed the clinical information of 169 patients who underwent radical nephrectomy and thrombectomy. Overall and cancer-specific survival rates were analyzed. Univariate and multivariate analyses were used to investigate the potential prognostic factors. Results. The median survival time was 63 months. The five-year overall survival and cancer-specific survival rate were 53.6 % and 54.4 % for all patients. For all patients, significant survival differenc
