In 2011, the Food and Drug Administration approved the first checkpoint inhibitor for the treatment of advanced melanoma, and since then, checkpoint inhibitors have demonstrated efficacy in many other tumor types. Given the frequent use of immune checkpoint inhibitors in a wide range of cancers today, the diagnosis and management of their immune-mediated toxicities need special attention. One of the most common is immune-mediated colitis. Workup and management of immune-mediated colitis can be challenging and is the purpose of this review. KEY POINTS Rate of immune mediated colitis differ from different kind of immune checkpoint inhibitor treatment. To work up immune-mediated colitis, tests to rule out infectious etiologies of diarrhea, colonoscopy and abdominal image will help to differentiate immune mediated colitis from colitis from other etiology. Patients with mild colitis can be managed with supportive therapies alone, but more severe cases may require immunomodulators such as steroid. Refractory cases may require tumor necrosis factor (TNF) inhibitors, such as infliximab in addition to steroid treatment. © AlphaMed Press 2019.BACKGROUND The fluoropyrimidines, 5-fluorouracil (5-FU) and capecitabine, are commonly used chemotherapeutic agents that have been associated with coronary vasospasm. METHODS In this retrospective case-control study, we identified patients at our institution who received 5-FU or capecitabine in 2018. We compared characteristics of patients who experienced cardiotoxicity with controls. We described phenotypes and outcomes of cardiotoxic cases. RESULTS We identified 177 patients who received fluoropyrimidines. After adjudication, 4.5% of the cohort met the criteria for cardiovascular toxicity. Coronary artery disease was more common among ca
