[Meta-analysis of proximal gastrectomy and total gastrectomy for cancer of cardia and fundus].

ABSTRACT

OBJECTIVE: To assess the value of proximal gastrectomy (PG) and total gastrectomy (TG) for the treatment of cancer of cardia and fundus. METHODS: Publications on comparision between PG and TG in the treatment of cancer of cardia and fundus were collected, the data from the publications were matched with the PG group and the TG group respectively according to its corresponding surgical resection, and the data on postoperative complications, motality and 5-year survival rate were meta-analyzed by fixed effect model and random effect model. RESULTS: Thirteen reseaches on 2 219 patients were included in this study, 2 of which were randomly controlled studies. There were no significant differences in the postoperative complications (OR=1.00, 95%CI 0.44-2.28,P>0.05) and mortality (OR=1.25, 95%CI 0.62-2.48,P>0.05) between the PG group and the TG group, while there was significant difference in the 5-year survival rate (HR=0.87, 95%CI 0.76-0.99,P=0.04). The 5-year survival rate in the TG group was higher than that in the PG group. CONCLUSION: Total gastrectomy for the treatment of cancer of cardia and fundus has better long-term therapetic effect.
