Histological complete response in a case of advanced gastric endocrine carcinoma treated by irinotecan plus cisplatin

Abstract

A 65-year-old man was admitted because of epigastralgia and body weight loss. A 50-mm tumor found at the lesser curvature of the gastric antrum was histologically diagnosed as endocrine carcinoma. A computed tomograpy (CT) scan showed liver metastasis and multiple lymph node metastasis. We started chemotherapy with irinotecan and cisplatin every 4 week. After three courses of treatment, the primary lesion was estimated PR, the metastasis CR, and the synthesis PR. Then we performed distal gastrectomy with lymph node dissection. Histological findings revealed no cancer cells.
