Clinical Features of Synchronous and Metachronous Superficial ESCC

Overview

This study investigates the clinicopathologic characteristics of synchronous and metachronous superficial esophageal squamous cell carcinoma (ESCC) following endoscopic submucosal dissection (ESD). It highlights the importance of long-term surveillance due to the high incidence of multiple lesions in ESCC patients.

Background

Esophageal cancer, particularly esophageal squamous cell carcinoma (ESCC), is a significant global health concern, ranking as the eighth most prevalent cancer and the sixth leading cause of cancer-related mortality. Early detection and management are critical, as ESCC can progress rapidly, necessitating effective surveillance strategies post-ESD to monitor for synchronous and metachronous lesions.

Data Highlights

No numerical data available in the source material.

Key Findings

• 318 ESCC lesions were identified in 199 patients, with 307 lesions included in the final analysis.
• Patients with synchronous and metachronous lesions exhibited distinct clinicopathologic features compared to initial lesions.
• Endoscopic submucosal dissection (ESD) was the primary treatment for both initial and secondary lesions.
• High-resolution endoscopy was utilized for follow-up, with surveillance intervals approximately every 6 months.
• Curative resection was defined based on histological findings, emphasizing the importance of negative margins and absence of vascular invasion.

Clinical Implications

The findings underscore the necessity for vigilant endoscopic surveillance in ESCC patients post-ESD, given the risk of synchronous and metachronous lesions. Clinicians should consider individualized follow-up strategies to optimize early detection and management of new lesions.

Conclusion

This study enhances understanding of the clinical behavior of synchronous and metachronous ESCC, reinforcing the need for structured surveillance protocols following ESD to improve patient outcomes.
