ROLE OF MICRORNA IN PREDICTING OF ADENOCARCINOMA DEVELOPMENT IN BARRETT’S ESOPHAGUS

Area of Science:

• Gastroenterology and Molecular Biology
• Oncology
• Esophageal Diseases

Background:

• Barrett's esophagus is a precursor to esophageal adenocarcinoma.
• Neoplastic progression involves multistage changes in esophageal mucosa.
• MicroRNA-21 (miR-21) is implicated in various cancers.

Purpose of the Study:

• To assess the expression level of microRNA-21 in patients with Barrett's esophagus.
• To correlate miR-21 expression with the degree of metaplasia and dysplasia.
• To explore the potential of miR-21 as a biomarker for esophageal adenocarcinoma.

Main Methods:

• Analysis of microRNA-21 expression in esophageal biopsy samples.
• Quantification of miR-21 levels in 25 patients with varying degrees of metaplasia and dysplasia.
• Correlation of miR-21 expression with histopathological findings.

Main Results:

• MicroRNA-21 expression levels varied based on the presence and severity of neoplastic changes.
• Elevated miR-21 expression was observed in columnar-celled metaplasia and intraepithelial neoplasia.
• Increased miR-21 was also noted in cases of esophageal adenocarcinoma.

Conclusions:

• MicroRNA-21 expression is associated with neoplastic progression in Barrett's esophagus.
• miR-21 may serve as a valuable biomarker for identifying high-risk patients.
• Assessing miR-21 levels in biopsy material could inform treatment strategies for gastroesophageal reflux disease patients.
