Abstract

Background: Despite the comparable results between ESD and gastrectomy reported in multiple Asiatic studies, limited data are currently present on the long-term efficacy of ESD for EGC in Western countries. The aim of this study was to compare the short- and long-term outcomes of the endoscopic submucosal dissection and surgery for non-diffuse early gastric cancer treatment in a Western cohort of patients. Methods: All patients with a diagnosis of intestinal type EGC located in the middle and lower third of the stomach from 2005 to 2015 were enrolled in the study. All patients completed a 5-year follow-up. Patients were divided according to the procedure performed (ESD/subtotal gastrectomy). The two groups were matched for age, gender, ASA score, tumor dimension, and grade of infiltration (mucosa/submucosa). Results: After matching, 84 patients (42 per group) were included in the analysis. Peri-procedural morbidity rate was 7.1% and no difference was observed between the two groups (4.8% vs 9.5% for ESD and STG groups, respectively; p = 0.3). Similar results in terms of 5-year OS and DFS were observed for ESD and STG (77.7% vs 71.8% ; p = 0.78 and 74.9% vs 72% ; p = 0.7, respectively). At the multivariate analysis, ASA3 score was recognized as the only negative predictor factor for the 5-year OS (OR 6.2; 95% CI 2.2–16.8; p < 0.001). Regarding the DFS, both ASA3 score (OR 4.4; 95% CI 1.7–10.9; p < 0.001) and submucosal infiltration(OR 5.1; 95% CI 1.2–22.4 ; p = 0.02) were identified as independent risk factors for a worse outcome. Conclusions: Our results confirm the safety and feasibility ESD for EGC treatment in a Western setting. In addition, this is one of the few reports showing comparable results both in terms of short- and long-term outcomes between ESD and surgery for intestinal type ECG treatment in Western countries.
