Cancer survivors aged 40 years or elder are associated with high risk of chronic kidney disease: the 2010-2012 Korean National Health and Nutrition Examination Survey.
BACKGROUND
The number of cancer survivors is increasing globally and recently, higher rates of comorbidities in cancer survivors have been reported. However, no studies have investigated whether cancer survivors have a higher risk of chronic kidney disease (CKD). Accordingly, our study evaluated the association between cancer survivors and the risk of CKD using the 2010-2012 Korean National Health and Nutrition Examination Survey.


METHODS
A total of 11,407 participants aged 40 years and over were categorized into two groups according to cancer experience. Multiple variables were compared and the odds ratios (ORs) for CKD prevalence were calculated using a weighted logistic regression analysis between the two groups.


RESULTS
Cancer survivors were older than were those in the non-cancer group, on average, the percentages of glomerular filtration rate(GFR) lower than 60mL/min/1.73m2, proteinuria, and CKD were significantly higher in cancer survivors when compared to controls. Weighted logistic regression analyses demonstrated that cancer survivors had a higher risk for CKD after adjusting for multiple variables (OR (95% confidence interval), 2.88 (1.48- 5.59)).


CONCLUSIONS
Our study demonstrated a possible association between CKD and cancer survival in Korean adults. Identifying and correcting risk factors for cancer survivors would positively affect prevention of CKD and result in a better cancer prognosis.
