Incidence, predictors and associated outcomes of renal cell carcinoma in long-term dialysis patients.

We carried out an analysis of the United States Renal Data System to determine the incidence, risk factors and prognosis of renal cell carcinoma (RCC) in a national population of patients receiving incident long-term dialysis. In Cox regression, male gender, older age, end-stage renal disease caused by obstruction, tuberous sclerosis, focal segmental glomerulosclerosis, as well as acquired renal cysts, were independently associated with RCC. Most cases of RCC in incident long-term dialysis patients occurred in patients without acquired renal cysts. A diagnosis of RCC was associated with increased risk of subsequent mortality overall and in all high-risk groups. Published by Elsevier Inc.
