Cancer risk in maintenance hemodialysis patients has been studied epidemiology, which might be influenced by various factors. On the contrary, investigation of cancer-bearing in non-dialysis chronic kidney disease patients has been rarely reported. Recently, we revealed relatively frequent past history of both colorectal cancer and renal cell carcinoma ahead of dialysis introduction and prevalence of colorectal cancer during the dialysis introduction period. In this article, we discuss the pathological relationship between chronic kidney disease and colorectal cancer and furthermore outline the susceptibility of chronic kidney disease after treatment of renal cell carcinoma.
