A 60-year-old male was found to have advanced gastric cancer and multiple lymph node metastases. Since curative surgery was concluded to be unfeasible, we tried neoadjuvant chemotherapy with the aim of controlling the lymph node metastasis. S-1 (80 mg/m2) was administered orally for two weeks then followed by 2-week rest period. CDDP (60 mg/ m2) and docetaxel (40 mg/m2) were simultaneously administered on day 1. Two courses of treatment resulted in marked shrinkage of the primary lesion and a reduction in size of the lymph nodes. The results were evaluated as a clinical PR based on RECIST, and radical resection was considered possible. The patient experienced a grade 3 leukocytopenia and neutropenia as adverse events of the chemotherapy. Total gastrectomy, splenectomy, and D2 lymph node dissection were performed with curative intent, and the postoperative course was uneventful. Histological examination of the surgical specimens revealed almost complete disappearance of cancer cells in the primary lesion in the stomach and complete disappearance in the lymph nodes. Pathological efficacy was Grade 2. The patient experienced a grade 3 appetite loss, and the adjuvant chemotherapy (S-1 regimen) was discontinued. The patient died of peritoneal dissemination eight months after the operation. We concluded that DCS as neoadjuvant chemotherapy was a promising strategy for patients with highly advanced gastric cancer because of its rapid antitumor effect.
