[A Case of Ileal Cancer Treated with Multidisciplinary Therapy].

A 66-year-old man was suspected of having an intestinal obstruction caused by a tumor in the small intestine after a close examination of vomiting and abdominal pain. Intestinal decompression was performed using an ileus tube, and small bowel endoscopy revealed a circumferential type 2 tumor of the ileum and a poorly differentiated adenocarcinoma on biopsy. The patient was referred to our department with a diagnosis of primary ileal cancer(cT2N1M0, cStage ⅢA). The patient underwent laparoscopic partial resection of the small intestine and lymph node dissection. Partial resection of the small intestine was performed 10 cm from the primary tumor, and lymph node dissection was performed up to the left margin of the SMV. The postoperative diagnosis was primary ileal cancer(pT3N1aM0, pStage ⅢA). The patient was administered CapeOX as adjuvant chemotherapy for 6 months. The patient has been alive since then without any recurrence. We report a case of ileal cancer that was treated with surgical therapy and postoperative adjuvant chemotherapy, with no recurrence.
