Objective. To investigate the efficacy of surgery in the treatment of metastatic renal cell carcinoma (mRCC) and to identify prognostic factors. Methods. A single center retrospective study of 96 patients with mRCC from December 2004 to August 2013. Results. The median follow-up time was 45 months. Thirty-one (32.3%) of the patients received complete resection of metastatic sites, 11 (11.5%) of the patients underwent incomplete resection of metastatic sites, and 54 (56.3%) of the patients received no surgery. In the univariate Kaplan-Meier analysis, the median overall survival times of the three groups were 52 months, 16 months, and 22 months, respectively (). The difference in the overall survival time was statistically significant between complete resection and no surgery groups (HR = 0.43, ), while there was no significant difference between the incomplete metastasectomy and no surgery groups (HR = 1.80, ). According to the multivariate Cox regression analysis, complete metastasectomy (HR = 0.49, ), T stage > 3 (HR = 1.88, ), disease free interval <12 months (HR = 2.34, ), and multiorgan involvement (HR = 2.00, ) were significant prognostic factors. Conclusion. In the era of targeted therapy, complete metastasectomy can improve overall survival. Complete metastasectomy, T stage > 3, disease free interval <12 months, and multiorgan involvement are independent prognostic factors.
