A statistical analysis was performed using the Cox model to estimate outcome indicators. RESULTS： There was a significant difference in the recurrence rate between lymph nede-negative and lymph node-positive patients （14.4% vs 41.0%, P〈0.001）. The 5-year survival rate was significantly lower in lymph node-positive than in lymph node-negative patients （31.1% vs 77.4%, P〈0.001）. Univariate analysis revealed that the following factors influenced the 5-year survival rate： patient age, tumor size, depth of invasion, tumor location, operative type, and tumor stage at initial diagnosis. The Cox proportional hazard regression model revealed that tumor size, serosal invasion, and curability were independent, statistically significant, prognostic indicators of lymph node-negative gastric carcinoma. CONCLUSION： Lymph node-negative patients have a favorable outcome attributable to high curability, but the patients with relatively large tumors and serosal invasion have a poor prognosis. Curability is one of the most reliable predictors of long-term survival for lymph nodenegative gastric carcinoma patients.展开更多

In September 2008,he subsequently underwent a laparotomy with a peritonectomy,omentectomy, splenectomy,and a Hartmann procedure.Hyperthermic intraperitoneal oxaliplatin 750 mg was administered. The patient was discharged with no postoperative complications and has been well with postoperative FOLFOX chemotherapy.展开更多
