A 64-year-old man with gastric tumor in the antrum had been diagnosed with gastric neuroendocrine carcinoma(NEC) by biopsy and multiple lymph node metastases(#3 and #6)by abdominal computed tomography. After staging laparoscopy showed that there were no non-curative factors, neoadjuvant chemotherapy(S-1/cisplatin[CDDP]: 2 courses)and distal gastrectomy and D2 lymph node dissection were performed. The pathological diagnosis was shown as pathological complete response(pCR). After adjuvant chemotherapy(S-1/CDDP: 2 courses, S-1: 6 courses)was administered, the patient is alive at 8 years without recurrence.
