[A Patient with Stage IV Gastric Cancer Who Survived More Than Five Years after Gastrectomy].

The prognosis of patients with Stage IV gastric cancer is generally poor. The 5-year overall survival rate is less than 10%. The patient was a 73-year-old man with Stage IV gastric cancer. Before chemotherapy, peritoneal dissemination was observed using staging laparoscopy. The patient received first-line chemotherapy with TS-1 plus CDDP. Renal function worsened and consequently the therapy was stopped. He received 3 courses of chemotherapy with weekly PTX. The peritoneal dissemination had disappeared by the second staging laparoscopy and he underwent distal gastrectomy. The final diagnosis was pT4a, ly2, v1, pN2(4/16),M0, fStage III B. The patient received adjuvant chemotherapy of TS-1 for 4 years and 8months after gastrectomy. More than 5 year after gastrectomy, the patient is alive without recurrence.
