Endoscopic therapy for Barrett's high grade dysplasia and intramucosal esophageal cancer is effective in community clinical practice by advanced endoscopists following multidisciplinary approach.

Abstract：

:Barrett's esophagus with high-grade dysplasia (BEHGD) and intramucosal esophageal adenocarcinoma (IMC) can be treated by radiofrequency ablation (RFA) and endoscopic mucosal resection (EMR). Efficacy of RFA and EMR in academic medical centers has been demonstrated in previous studies. However, the clinical effectiveness of this approach in community clinical practice is not fully established.All patients with biopsy-proven BEHGD and IMC (T1a), who were treated endoscopically between 2007 and 2014, were prospectively enrolled. Treatment algorithms were determined by consensus opinion after presentation at gastrointestinal tumor board. Patients underwent EMR and/or RFA until eradication-of-dysplasia and complete remission of intestinal metaplasia (CRIM) was achieved. Patients were then enrolled in an endoscopic surveillance program.A total of 60 patients underwent endoscopic therapy for BEHGD (32) or IMC (28). Median length BE was 4 cm. Forty-six patients had EMR. Median treatment interval was nine months. Median follow-up was 33 months (Interquartile range: 16-50). Fifty-five (92%) patients achieved eradication-of-dysplasia and 52(87%) CRIM. One patient with BEHGD did not achieve any benefit six months into treatment. Nine (15%) patients relapsed after CRIM with nondysplastic-BE (6), BE with low-grade dysplasia (1), and BEHGD (2). After retreatment, eradication-of-intestinal metaplasia was achieved in five patients. BE length was a negative predictor for achieving CRIM (OR 0.81; P = 0.04). There were no procedure-related severe complications. Eleven patients with prior EMR developed symptomatic strictures, which were all successfully dilated.Endoscopic management of BEHGD and IMC can be safely and effectively performed in a community clinical practice similarly to high-volume academic medical centers when performed by advanced endoscopists following multidisciplinary approach.
