ABSTRACT
OBJECTIVE:
Endoscopic therapy is increasingly being used in the treatment of high-grade intraepithelial neoplasia (HGIN) and mucosal adenocarcinoma (BC) in patients with Barrett's oesophagus. This report provides 5 year follow-up data from a large prospective study investigating the efficacy and safety of endoscopic treatment in these patients and analysing risk factors for recurrence.DESIGN:
Prospective case series.SETTING:
Academic tertiary care centre. PATIENTS Between October 1996 and September 2002, 61 patients with HGIN and 288 with BC were included (173 with short-segment and 176 with long-segment Barrett's oesophagus) from a total of 486 patients presenting with Barrett's neoplasia. Patients with submucosal or more advanced cancer were excluded.INTERVENTIONS:
Endoscopic therapy. MAIN OUTCOMEMEASURES:
Rate of complete remission and recurrence rate, tumour-associated death.RESULTS:
Endoscopic resection was performed in 279 patients, photodynamic therapy in 55, and both procedures in 13; two patients received argon plasma coagulation. The mean follow-up period was 63.6 (SD 23.1) months. Complete response (CR) was achieved in 337 patients (96.6%); surgery was necessary in 13 (3.7%) after endoscopic therapy failed. Metachronous lesions developed during the follow-up in 74 patients (21.5%); 56 died of concomitant disease, but none died of BC. The calculated 5 year survival rate was 84%. The risk factors most frequently associated with recurrence were piecemeal resection, long-segment Barrett's oesophagus, no ablative therapy of Barrett's oesophagus after CR, time until CR achieved >10 months and multifocal neoplasia.CONCLUSIONS:
This study showed that endoscopic therapy was highly effective and safe, with an excellent long-term survival rate. The risk factors identified may help stratify patients who are at risk for recurrence and those requiring more intensified follow-up.
