Abstract | BACKGROUND: PATIENTS AND METHODS: A single center, retrospective case-control study was performed of all ICI-treated patients at Memorial Sloan Kettering Cancer Center between January 2011 and July 2020. ICI-related EPI patients had steatorrhea with or without abdominal discomfort or weight loss, started pancrelipase after initiation of ICI, and demonstrated symptomatic improvement with pancrelipase. Controls were matched 2:1 by age, race, sex, cancer type, and year of ICI start. RESULTS: Of 12 905 ICI-treated patients, 23 patients developed ICI-related EPI and were matched to 46 controls. The incidence rate of EPI was 1.18 cases per 1000 person-years and the median onset of EPI was 390 days after the first dose of ICI. All 23 (100%) EPI cases had steatorrhea that improved with pancrelipase, 12 (52.2%) had weight loss, and 9 (39.1%) had abdominal discomfort; none had changes of chronic pancreatitis on imaging. Nine (39%) EPI patients had episodes of clinical acute pancreatitis preceding the onset of EPI, compared to 1 (2%) control (OR 18.0 (2.5-789.0), P < .001). Finally, the EPI group exhibited higher proportions of new or worsening hyperglycemia after ICI exposure compared with the control group (9 (39.1%) vs. 3 (6.5%), P < .01). CONCLUSION: ICI-related EPI is a rare but clinically significant event that should be considered in patients with late onset diarrhea after ICI treatment and often is associated with development of hyperglycemia and diabetes.
