BACKGROUND/AIMS: Although palliative gastrectomy for advanced gastric cancer may be favorable in selected patients presenting with bleeding and obstruction, little has been reported about the clinical significance of palliative gastrectomy, including prognosis. METHODOLOGY: A retrospective comparison between 84 patients with palliative gastrectomy (PG group) and 100 patients with unresectable operation (UO group) for advanced gastric cancer was carried out. RESULTS: The incidence of serosal invasion, peritoneal dissemination, hepatic and lymph node metastases, and undifferentiated tissue type in the UO group were significantly higher than in the PG group. Median survival after operation in the PG group (20.6 months) was significantly longer than in the UO group (5.7 months). Also, in stage IVb patients, median survival time in the PG group (10.2 months) was significantly longer than in the UO group (5.0 months). However, median survival in the patients with synchronous liver metastasis between PG (8.4 months) and UO (4.6 months) groups was not significantly different. Survival rates after operation of 6 months, 1 year and 2 years in all patients between the palliative gastrectomy group versus UO group were 83.6% versus 38.3% (P < 0.01), 63.0% versus 9.3% (P < 0.01) and 35.2% versus 0% (P < 0.01), respectively. CONCLUSIONS: Palliative gastrectomy compared to unresectable operation may be effective for improvement of prognosis even if stage IVb patients with peritoneal dissemination and/or distant lymph node metastasis. However, it may be unfavorable on survival of patients with synchronous liver metastasis.
