title: [A case of gastric neuroendocrine carcinoma with liver metastasis and portal vein invasion successfully treated by S-1 and cisplatin chemotherapy].
abstract: A 66-year-old man presented with anemia. Endoscopy revealed an elevated lesion with ulceration in the posterior wall of the lesser curvature of the lower gastric body. Endoscopic biopsy demonstrated pathological diagnosis, neuroendocrine carcinoma. A computed tomography scan showed liver metastasis and portal vein invasion. We started chemotherapy with S-1 and cisplatin. After six courses of treatment over seven months, partial response was assessed. We are continuing this chemotherapy now.
