Concurrent Chemoradiation-related Superior Mesenteric Artery Occlusion in the Patient with Advanced Endometrioid Endometrial Cancer after Surgery

The incidence of endometrial cancer (EC) has increased and it has approximately 16% of gynecologic cancers in Korea. For locoregional or distant recurrence, adjuvant treatment after surgery is very important in patients with intermediateor high-risk EC (IHR-EC). Recently clinical trials for treating patients with IHR-EC are focused on the effi cacy of concurrent chemoradiation (CCR). However, increase in intestinal complications in the group of radiotherapy combined with chemotherapy was reported. In case of chemoradiation-related superior mesenteric artery (SMA) occlusion, it could be fatal nevertheless with intensive care. We present a case report of radiation-related arteritis leading to stenosis in SMA, which led the patient with EC to death in a year after CCR.
