Prevalence and Risk Factors for Intraductal Papillary Mucinous Neoplasm in Patients With Chronic Kidney Disease: A Single-Center Case-Control Study.

OBJECTIVES The exact prevalence for intraductal papillary mucinous neoplasm (IPMN) in patients with chronic kidney disease (CKD) remains unknown. In this single-center case-control study, we aimed to study the prevalence and risk factors for IPMN in patients with CKD. METHODS We performed a retrospective case-control study comparing patients with and without CKD who had magnetic resonance imaging of the abdomen performed between January 2018 and December 2018. Patient demographic, clinical, and imaging metrics were extracted from chart review. The prevalence of IPMN was compared between the 2 groups. RESULTS A total of 800 patient charts were reviewed. There were 400 patients with CKD compared with an age-matched control group of 400 patients without CKD. The total prevalence of IPMN in patients with CKD was 13.7% (55/400) compared with 7.8% (29/400; P = 0.002) in non-CKD patients. The prevalence of diabetes mellitus was significantly higher in the CKD group (41% vs 14%, P = 0.0001). The percentage of patients consuming alcohol was significantly higher in the non-CKD group (23% vs 35%, P = 0.002). CONCLUSIONS Patients with CKD have a significantly higher prevalence of IPMN compared with non-CKD patients. Larger population-based studies are needed to confirm these findings.
