Core Tip

Core Tip: Immune checkpoint inhibitor-mediated colitis (IMC) is a common adverse event following immune checkpoint inhibitor (ICI) therapy for cancer. We sought to determine the association of IMC with overall survival (OS) and progression-free survival (PFS) among cancer patients treated with ICI and identify clinical predictors of IMC. We performed a retrospective case-control study including 64 ICI users who developed IMC. In multivariate logistic regression analysis, IMC was significantly associated with a higher OS but not PFS. IMC was significantly associated with OS greater than 12 mo. Vitamin D supplementation was associated with increased risk of IMC.
