Endoscopic submucosal dissection for malignant esophageal lesions

Area of Science:

• Gastroenterology
• Oncology
• Endoscopic Surgery

Background:

• Esophageal cancer incidence is rising with poor prognosis.
• Endoscopic submucosal dissection (ESD) is effective for early gastric cancer.
• ESD use is increasing for early esophageal squamous cell cancer (SCC) in Japan.

Purpose of the Study:

• To evaluate the efficacy and challenges of ESD in esophageal cancers.
• To explore combined treatment modalities for Barrett's neoplasia and SCC.
• To identify methods for preventing post-ESD complications.

Main Methods:

• Review of ESD application in early esophageal squamous cell cancer (SCC) and Barrett's neoplasia.
• Analysis of treatment outcomes and complications.
• Investigation of adjunctive therapies like radiofrequency ablation and chemoradiation.
• Assessment of steroid therapy for preventing post-ESD stenosis.

Main Results:

• ESD offers long-term results comparable to early gastric cancer for esophageal SCC in Japan.
• Western applications of ESD for Barrett's neoplasia face challenges with resection rates and metachronous lesions.
• Combined therapies and steroid use show promise in improving outcomes and managing complications.

Conclusions:

• ESD is a viable option for early esophageal SCC, with ongoing research for Barrett's neoplasia.
• Multimodal approaches and preventative strategies like steroid therapy are crucial for optimizing ESD outcomes.
• Further research is needed to overcome challenges in Western settings and refine treatment protocols.
