Abstract:
OBJECTIVETo compare the survival rate of proximal gastrectomy and total gastrectomy in the treatment of esophagogastric junction (EGJ) adenocarcinoma (Siewert II( types), and to provide reference for clinical choice.
METHODSA total of 533 patients with Siewet II( type EGJ adenocarcinoma were screened. All the patients underwent radical operations and were pathologically diagnosed as Siewet II( type EGJ adenocarcinoma in Xijing Hospital of Digestive Diseases from May 2008 to March 2014. These patients all had complete followed-up data. Finally, 234 patients were enrolled into the retrospective study, and divided into proximal gastrectomy group(117 patients) and total gastrectomy group (117 patients) based on the matching of age, sex, tumor size, TNM staging, and differentiation. The survival rate was compared between the two groups.
RESULTSIn proximal gastrectomy and total gastrectomy group, the overall 3-year survival rate was 65.6% and 62.6% respectively, and the overall 5-year survival rate was 53.8% and 44.5% respectively. No significant difference was found between the two groups (P=0.768). In subgroup analyses of 3-year survival rate between proximal gastrectomy group and total gastrectomy group, the results were as follows: 72.8% and 80.4% respectively (P=0.423) for tumor diameter ≤4 cm, 57.9% and 46.5% (P=0.239) for tumor diameter >4 cm, 83.3% and 83.3% (P=0.998) for high differentiated EGJ adenocarcinoma, 68.2% and 53.3% (P=0.270) for moderate differentiated EGJ adenocarcinoma, 56.1% and 69.6% (P=0.280) for poorly differentiated EGJ adenocarcinoma, 64.8% and 56.0% (P=0.451) for mucinous EGJ adenocarcinoma, 80.0% and 76.9% (P=0.912) for T1-2 stage EGJ adenocarcinoma, 64.3% and 60.4% (P=0.610) for T3 stage, 50.0% and 62.5% (P=0.953) for T4a stage, 92.3% and 100% (P=0.380) for stage I( EGJ adenocarcinoma, 79.6% and 66.3%(P=0.172) for stage II(, 42.6% and 49.5% (P=0.626) for stage I I(. All above differences between the two groups were not significant(all P>0.05).
CONCLUSIONProximal gastrectomy and total gastrectomy are comparable in terms of 3-year and 5-year survival rates.
