[A Case of Neuroendocrine Carcinoma of Ascending Colon with Early Recurrence after Surgery].

A 65-year-old male received the positive result of fecal occult blood. Colonoscopy was performed to reveal a tumor in the ascending colon. The result of biopsy was neuroendocrine carcinoma. Under the preoperative diagnosis of neuroendocrine carcinoma in the ascending colon, cT3N0M0, cStage Ⅱ, laparoscopic ileocecal resection with D3 lymph node dissection was performed. The pathological result was neuroendocrine carcinoma in the ascending colon, pT4aN2M0, pStage Ⅲc. The R0 resection was achieved. As adjuvant chemotherapy, the regimen of cisplatin plus irinotecan was administered for 4 courses. No recurrence was seen until 9 months after the operation, when multiple peritoneal and hepatic metastasis were detected on CT scan. The chemotherapy regimen of etoposide plus carboplatin was started and is now ongoing. The patient is now alive 13 months after the operation.
