Are chronic dialysis patients at increased risk for cancer?
This review summarizes the plausible mechanisms of carcinogenesis, critically analyzes the literature on cancer risk and discusses issues of cancer screening in chronic dialysis patients. Despite conflicting results among various studies, there is sufficient evidence to conclude that there is a heightened incidence of at least some cancers in dialysis patients. The data most convincingly support an increased risk of genitourinary malignancies. Screening for the common solid organ cancers (prostate, colon, breast and cervix) should be individualized, and is appropriate only for the minority of patients with a life expectancy on dialysis of 10 years or longer. Further research is needed before routine screening for bladder or renal cell cancers can be recommended.
