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

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 estimated 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.
