Surgical Treatment of Gastric Adenocarcinoma: Total vs. Subtotal Gastrectomy. A Single Centre Experience

Abstract

SummaryThe purpose of this study is to analyze postoperative morbidity and mortality of patients undergoing various types of gastric resection for adenocarcinoma in a single centre and to evaluate the oncological outcome regarding to completeness of resection.Ninety-eight patients with gastric adenocarcinoma were involved in the present study. We observed postoperative complications or death and a length of hospital stay, completeness of resection, TNM staging. Differences in overall survival between total (TG) and subtotal gastrectomy (SG) were analyzed using analysis of variance (ANOVA) and Kruskal-Wallis test with p < 0,05 value.There was no statistically significant difference in overall survival between both groups (p = 0,409). R0 vs. R1 resection could be evaluated in 72 patients with no difference in survival among them (p = 0,003). The median time to recurrence were 12 and 11 months in R0 and R1 resection, respectively. The median time of overall survival were 20 and 15,5 months in R0 and R1 patients, but without statistical significance (p = 0,406). The only statistical difference was found in the length of survival between T1 and T3 stage (p = 0,009).If R0 resection could be achieved, there was no difference in overall survival and time to recurrence between TG and SG.
