title: [A case of gastric cancer with N2 lymph node metastasis and pancreatic invasion effectively treated with docetax-el/S-1 as a neoadjuvant chemotherapy].
abstract: A 74-year-old man was diagnosed with advanced gastric cancer(cStage III B). Laparotomy showed N2 lymph node metastasis and pancreatic invasion. Radical resection appeared impossible and was thus not performed. Chemotherapy consisting of a combination of S-1(80mg/m 2, 2-week administration and 1-week rest), and docetaxel(40mg/m2day 1)was administered with the expectation of tumor downstaging. A partial response(PR)was obtained after five courses of this regimen in which the primary lesion and lymph node swelling remarkably improved. Total gastrectomy, splenectomy, partial colectomy, and D2 lymph node dissection were then performed. Pathological analysis revealed very few cancer cells in the primary lesion and that the lymph nodes had become scarred and fibrotic. The histological appearance was judged to be grade 2 and the final diagnosis was T1N0H0P0CY0M0, fStage I A, curability A. Currently, more than 6 years and 4 months after the operation, the patient is alive without any evidence of recurrence. Thus, docetaxel/S-1 combination therapy was an effective neoadjuvant chemotherapy for this case of advanced gastric cancer.
