Characterization of subepithelial tumors of upper gastrointestinal tract by endoscopic ultrasound

Area of Science:

• Gastroenterology
• Oncology
• Medical Imaging

Background:

• Esophageal gastrointestinal stromal tumors (GISTs) are rare mesenchymal neoplasms originating from interstitial cells of Cajal.
• GISTs are most commonly found in the stomach and small intestine, with esophageal involvement accounting for less than 1% of all cases.

Discussion:

• Endoscopic resection is effective for small, localized esophageal GISTs.
• Larger tumors necessitate multidisciplinary approaches for optimal oncological outcomes.
• Endoscopic ultrasound (EUS) is crucial for evaluating subepithelial tumors in the upper gastrointestinal tract, as standard endoscopy is insufficient.

Key Insights:

• EUS provides accurate tumor size assessment for esophageal GISTs.
• EUS-guided fine needle aspiration enables biopsy for precise treatment planning.
• EUS is essential for comprehensive diagnosis, staging, and management of subepithelial upper gastrointestinal masses.

Outlook:

• Further research into multidisciplinary strategies for advanced esophageal GISTs is warranted.
• Continued integration of EUS in the diagnostic and management algorithms for esophageal GISTs is expected.
• Advancements in endoscopic techniques may improve outcomes for esophageal GIST patients.
