Molecular alterations in esophageal tissue offer promising biomarkers for Barrett
Area of Science:
- Molecular pathology and biomarker discovery in gastrointestinal diseases.
Background:
- Barrett's Esophagus (BE) and esophageal adenocarcinoma exhibit distinct molecular changes.
- Identifying reliable biomarkers is crucial for managing BE and predicting cancer risk.
Purpose of the Study:
- To review and highlight promising molecular biomarkers for esophageal diseases, particularly BE.
- To assess the current status and future potential of various biomarker types.
Main Methods:
- Comparative analysis of molecular profiles (DNA, epigenetics, RNA, proteins) in normal, BE, and adenocarcinoma tissues.
- Review of established and emerging biomarker technologies for esophageal diagnostics.
Main Results:
- Multi-target esophageal cytology DNA assays (methylated-DNA) and Trefoil factor 3 immunohistochemistry are promising for BE management.
- MicroRNA, genomic instability measures, and novel biomarkers (VOCs, saliva microbiome) show potential but require further validation.
Conclusions:
- Distinct molecular signatures in esophageal tissues can serve as valuable disease-specific biomarkers.
- Established biomarkers show clinical promise, while novel approaches need extensive prospective validation for clinical utility.
