Renal Insufficiency According to Time after Cancer Diagnosis: Findings of a Nationwide Cross-Sectional Study

Abstract

Background: Little is known about the relationship between renal insufficiency and time after cancer diagnosis. Methods: The data of 71,302 individuals (aged 19 to 79 yr) that participated in the 2007-2019 Korean National Health and Nutrition Examination Surveys were subjected to analysis. Renal insufficiency was defined as an esti-mated glomerular filtration rate of < 60 ml/min/1.73 m2. Odds ratios of renal insufficiency were estimated using multivariate logistic regression models adjusted for potential covariates.Results: Of the 71,302 study subjects, 3.7% were cancer survivors and 2.2% were long-term (= 5 yr) survivors. Renal insufficiency was significantly more prevalent among short-term survivors, but not among long-term survi-vors, than among subjects without cancer. Conclusion: A cancer history of = 5 yr is not an independent risk factor of renal insufficiency.
