Purpose To investigate the impact of hemodialysis on survival in renal cell carcinoma (RCC) patients. Methods We studied 388 patients who underwent radical or partial nephrectomy for RCC at Toranomon Hospital from 2005 to 2013. Survival curves were drawn according to the Kaplan‐Meier method and compared with the log‐rank test. Multivariate analysis was performed using the Cox proportional hazards regression model to assess the prognostic influence of hemodialysis on cancer‐specific survival. Result Of the 388 patients, 66 were on hemodialysis and 322 were not on dialysis. In the hemodialysis patients, incidental diagnosis of RCC was less frequent than in the non‐dialysis patients. In addition, RCC was more likely to be multicentric (41% vs 1.2%), bilateral (14% vs 0.6%), and papillary (18% vs 7%) in hemodialysis patients. Moreover, tumors were smaller, the stage was lower, and the Fuhrman nuclear grade was higher in the patients on hemodialysis. The 5‐year cancer‐specific survival rate was 82.8% for hemodialysis patients and 93.5% for nondialysis patients. Multivariate analysis indicated that hemodialysis, stage, and Fuhrman nuclear grade were independent prognostic factors for RCC. Conclusions This study suggested that hemodialysis was an independent prognostic factor for cancer‐specific survival in RCC patients, along with the tumor stage and Fuhrman nuclear grade.
