Treatment Outcomes of Endoscopic Submucosal Dissection for Adenocarcinoma Originating from Long-Segment Barrett's Esophagus versus Short-Segment Barrett's Esophagus.
Digestion 2018
BACKGROUND: In recent years, effective outcomes of endoscopic submucosal dissection (ESD) for esophagogastric junction cancer including short-segment Barrett's esophagus (SSBE) cancer have been reported. However, the efficacy of ESD for long-segment Barrett's esophagus (LSBE) cancer is unknown.
AIM: To clarify the treatment outcomes of ESD for LSBE cancer versus SSBE cancer.
METHODS: A total of 86 patients with 91 superficial Barrett's esophageal adenocarcinomas who underwent ESD were enrolled; of these, 68 had underlying SSBE and 18 had LSBE. Procedure outcomes and prognosis were compared.
RESULTS: There was no significant difference in age and tumor diameter among patients. The only complication observed was stricture, but it was not significant (2 vs. 9%). No significant difference was observed in the negative horizontal margin rates (94.1 vs. 95.7%), R0 resection rates (83.8 vs. 82.6%), curative resection rates (72.1 vs. 73.9%), and noncurative factors. Both LSBE and SSBE cancer showed favorable 3-year overall survival rates (95.0 vs. 94.4%) in the median observation period of 28.5 months.
CONCLUSIONS: ESD for LSBE cancer achieved procedure outcomes and short-term prognosis comparable to SSBE. ESD has the potential to be an effective therapeutic option for esophageal neoplasms in patients with LSBE.
