Abstract:
The patient is a 79-year-old woman who visited her local doctor with a chief complaint of abdominal pain. A lower gastrointestinal endoscopy revealed a circumferential type 3 mass in the transverse colon. The patient was diagnosed with transverse colon cancer (cT3N0M0, cStage Ⅱa)and underwent laparoscopic transverse colectomy(D3). The postoperative course was good, and she was discharged on POD 9. Pathological results showed a diagnosis of medullary carcinoma(pT3N0M0, pStage Ⅱa)with MSI-high. The patient was treated with UFT/UZEL for 6 months as postoperative adjuvant chemotherapy. The patient has been recurrence-free for 1 year and 6 months postoperatively and is under outpatient follow-up. Medullary carcinoma is a rare histologic type that is estimated to account for 2-3% of all colorectal cancers. Medullary carcinoma of the colon is more common in elderly patients, women, and the right side of the colon, with a relatively favorable prognosis. We report a case of medullary carcinoma of the transverse colon in which the patient had a relatively long survival, with some discussion of the literature.
