Categorizing Risks within Barrett's Esophagus To Guide Surveillance and Interception; Suggesting a New Framework

Area of Science:

• Gastroenterology
• Oncology
• Pathology

Background:

• Barrett's esophagus is a precancerous condition with stepwise progression to esophageal adenocarcinoma (EAC).
• Current surveillance relies on demographic and clinical factors, with limited use of molecular biomarkers like p53 IHC.
• Existing surveillance strategies aim for early detection and intervention, but risk stratification can be refined.

Purpose of the Study:

• To review established and novel risk factors for Barrett's esophagus progression.
• To evaluate emerging risk stratification tools for clinical application.
• To propose a framework for integrating risk stratification into surveillance protocols.

Main Methods:

• Review of current literature on Barrett's esophagus progression and risk factors.
• Analysis of novel risk stratification tools, including non-endoscopic triage and biomarker panels.
• Development of a proposed framework for clinical risk stratification.

Main Results:

• Several demographic and clinical factors, such as segment length, are associated with EAC progression.
• Novel tools like non-endoscopic triage and commercial biomarker panels show promise for risk stratification.
• Current biomarker use (p53 IHC) is variable and not universally applied.

Conclusions:

• Refined risk stratification is needed to optimize Barrett's esophagus surveillance.
• Integrating novel tools can lead to more personalized and effective patient management.
• A new framework is proposed to guide the clinical application of risk stratification for EAC surveillance.
