The treatment for unresectable advanced gastric cancer with pyloric stenosis.

194 Background: Inability of oral intake due to advanced gastric cancer with pyloric stenosis (AGCPS) should be avoided, because the key drug of chemotherapy for gastric cancer is S-1 in Japan. We have performed palliative gastrectomy (PG), gastrojejunostomy (GJ) or stent placement (SP) for unresectable AGCPS. We investigated therapeutic outcomes (gastric outlet obstruction scoring system: GOOSS, chemotherapy introduction rate: CIR and median survival time: MST) of each therapy retrospectively. Methods: Between April 1999 and April 2013, 42 patients with unresectable AGCPS were included in this study (PG/GJ/SP, 13/10/19). We compared therapeutic outcomes (GOOSS, CIR and MST) between the 3 groups. Results: The demographic characteristics of patients were similar across the three groups. We evaluated the Glasgow Prognostic Score (GPS) of all cases before treatment. GPS tended to be 1 in the PG group, 0 in the GJ group and 2 in the SP group. The proportion of GPS 2 in the SP group was higher than in PG or GJ...
