The controversy regarding ablation for Barrett's esophagus without dysplasia

Molecular epidemiology of and genetic susceptibility to esophageal cancer

The following, from the 12th OESO World Conference: Cancers of the Esophagus, includes commentaries on clonal evolution in Barrett's carcinogenesis; biomarkers for early detection of esophageal cancer; the role of the methylguanine methyl transferase biomarker in the management of adenocarcinoma; and the discovery of high-risk genes in families.

Endoscopic therapies for Barrett's-associated dysplasia: a new paradigm for a new decade

The emergence of endoscopic therapies for Barrett's esophagus (BE)-associated dysplasia has significantly altered the management of this complex disease. Over the past decade, there has been a paradigm shift from that of pure surveillance to a more therapeutic approach in eradicating dysplastic BE. This strategy includes less invasive options than esophagectomy for high-grade dysplasia and early eradication of confirmed low-grade dysplasia. Although multiple modalities exist for endoscopic therapy, endoscopic mucosal resection coupled with radiofrequency ablation appears to be the most effective therapy, with minimal complications. Recent advances in endoscopic eradication therapies for dysplastic BE have fueled excitement for a significant weapon against the rising incidence of esophageal cancer.
