Treatment helps reduce risk of esophagus disorder progressing to cancer
Date:3/25/2014

l) and a reduced absolute risk of progression to cancer of 7.4 percent (1.5 percent vs 8.8 percent). Complete eradication of dysplasia occurred and persisted in the majority of patients in the ablation group.

The trial was terminated early due to the superiority of ablation for the primary outcome and concerns about patient safety should the trial continue.

"In this multicenter, randomized trial of radiofrequency ablation vs surveillance in patients with Barrett esophagus and a confirmed histological diagnosis of low-grade dysplasia, ablation substantially reduced [tumor] progression to high-grade dysplasia and adenocarcinoma over 3 years of follow-up. Patients with a confirmed diagnosis of low-grade dysplasia should therefore be considered for ablation therapy," the authors conclude.

Editorial: Radiofrequency Ablation for Barrett Esophagus With Confirmed Low-Grade Dysplasia

Klaus Monkemuller, M.D., Ph.D., F.A.S.G.E., of the University of Alabama at Birmingham, comments on the findings of this study in an accompanying editorial.

"The clinical trial by Phoa et al provides important evidence to support the use of radiofrequency ablation not only for patients with high-grade dysplasia and early cancer, but also for carefully selected patients [via screening and testing] with Barrett esophagus and confirmed low-grade dysplasia. A proactive endoscopic approach to eliminate dysplasia may result in reduced morbidity and mortality related to the progression of this disease."
