Radiofrequency ablation eliminates nondysplastic BE
Radiofrequency ablation (RA) is effective for the complete eradication of nondysplastic Barrett’s esophagus (BE), according to researchers from the Academic Medical Center in Amsterdam.
ABSTRACT: Studies finds RA, with or without prior endoscopic resection, proves safe for removal of Barrett’s esophagus and associated neoplasia.
Radiofrequency ablation (RA) is effective for the complete eradication of nondysplastic Barrett’s esophagus (BE), according to researchers from the Academic Medical Center in Amsterdam.
Roos E. Pouw, MD, and colleagues enrolled 44 patients who had BE (median of 7 cm) with early neoplasia. Visible lesions were endoscopically resected. Circumferential and focal ablation was repeated every 2 months until the entire Barrett epithelium was eradicated (Journal of Gastrointestinal Surgery online, August 13, 2008).
Among 31 patients, 16 first underwent endoscopic resection for early cancer, 12 had high-grade dysplasia, and 3 displayed low-grade dysplasia. After resection, the worst remaining histology was high-grade in 32 cases, low-grade in 10 cases, and 2 without dysplasia.
Post-ablation, complete histological eradication of all dysplasia and intestinal metaplasia was achieved in 43 patients.
Targeted Therapy First Strategy Reduces Need for Chemotherapy in Newly Diagnosed LBCL
December 7th 2025Lenalidomide, tafasitamab, rituximab, and acalabrutinib alone may allow 57% of patients with newly diagnosed LBCL to receive less than the standard number of chemotherapy cycles without compromising curative potential.
