There are still many unclear points regarding cancers occurring in dialysis patients. A questionnaire survey was conducted involving patients receiving dialysis treatment between 2015 and 2019 at 56 dialysis facilities in Okinawa Prefecture regarding any cancer history. During those five years, 408 cancers were diagnosed in 263 males and 145 females. In males, colorectal, kidney, and lung cancers were common, in that order. In females, breast, kidney, and colorectal cancers were common, also in that order. Lung cancer is often diagnosed early with the induction of dialysis and is common in the elderly, and the smoking rate among patients is also high. The prevalence of kidney cancer was high in both males and females, with a mean patient age of 65.6±11.1 years and the median time from the initiation of dialysis to onset of cancer being 12.4±8.9 years. In an analysis that included cancers before the start of dialysis, most cancers were diagnosed within five years after the induction of dialysis, followed by those within five years before dialysis. In addition, most cancers occurred within 1 year before or after the induction of dialysis. In the future, it will be necessary to clarify the characteristics of cancer in dialysis patients throughout Japan and adopt appropriate measures.
