[Gastric Neuroendocrine Carcinoma(NEC)Treated with CDDP plus CPT-11 Chemotherapy].

Abstract

A 69-year-old man with chronic gastritis, reflux esophagitis, esophageal hiatal hernia, and history of appendicitis surgery complained of difficulty swallowing. Upper gastrointestinal endoscopy revealed a 10 cm sized Type 3 gastric cancer. Immunostaining was positive for chromogranin A(2+), synaptophysin(3+), CD56(-), and Ki-67>70%. Contrast computed tomography(CT)showed upper gastric wall thickening, and #1, #3, #7, #8a, and #11p enlarged lymph nodes but no distant metastasis. We diagnosed gastric cancer, UM, Less, Type 3, gastric neuroendocrine carcinoma, cT4aN3M0P0CY0, Stage ⅢC. We administered 2 courses of CDDP plus CPT-11 chemotherapy, and a partial response was obtained for the primary gastric lesion and lymph node metastases. We subsequently performed open distal gastrectomy, D2 lymph node dissection, and splenectomy. Pathological examination confirmed that the lesion was gastric cancer, U, Less, Type 3, gastric neuroendocrine carcinoma, MP, Ul-Ⅱ(+), int, INF b, ly2, v0, PM0, DM0, R0, ypT2N2, Stage ⅡB, with a therapeutic value of Grade 2. The patient was discharged on day 15 after the surgery and received 2 courses of adjuvant chemotherapy with CDDP plus CPT-11. Nine months after the surgery, metastasis of the left adrenal grand was found. We performed open left adrenal gland resection and administered adjuvant S-1 chemotherapy.
