Long-term follow-up results of stepwise radical endoscopic resection for Barrett's esophagus with early neoplasia.


BACKGROUND AND AIMS Stepwise radical endoscopic resection (SRER) has shown to be effective in eradicating Barrett's esophagus (BE) and its associated dysplasia. The aim of this study was to assess the long-term durability after successful SRER for early Barrett's neoplasia. METHODS Patients treated with SRER for BE ≤5 cm with high-grade dysplasia (HGD) or early cancer (EC) and who had reached complete eradication of intestinal metaplasia (CE-IM) and neoplasia (CE-neo) were included. Primary outcomes were recurrence of neoplasia (HGD/EC), recurrence of dysplasia (indefinite for dysplasia included), and recurrence of endoscopically visible BE. Secondary outcomes were buried Barrett's glands, IM in biopsy specimens obtained distal to a normal-appearing neo-squamocolumnar junction (neo-SCJ), need for retreatment, and sustained CE-IM and CE-neo at the last follow-up endoscopy. RESULTS Seventy-three patients were included (64 men; mean age, 66 years; median BE, C2M3). Median follow-up was 76 months. Recurrence of neoplasia was observed in 1 patient (T1bN0M0) after 129 months of follow-up and was treated with curative surgery (annual incidence of .22% per patient-year of follow-up). In 4 patients, recurrence of dysplasia was found (.87% per patient-year of follow-up). Twelve patients had recurrent endoscopically visible BE after a median follow-up of 22 months (2.6% per patient-year of follow-up), mostly small islands or tongues. Five patients had a single finding of buried Barrett's glands (1.1% per patient-year of follow-up), and 27 patients (5.9% per patient-year of follow-up) showed IM in biopsy specimens just distal to the neo-SCJ, which was not reproduced in 56%. Retreatment was performed in 9 patients. CE-IM and CE-neo (excluding IM in the neo-SCJ) at the last follow-up endoscopy was seen in 95% and 97% of patients, respectively. CONCLUSIONS This study presents the longest published follow-up data on SRER to date. The 6-year outcomes show that successful SRER is a durable treatment for BE ≤5 cm with HGD/EC.
