Summary
Partial resection during endoscopic mucosal resection (EMR) for early gastric cancer reduces recurrence rates. Close follow-up is crucial for detecting recurrent cancers within the first year post-EMR for timely treatment.
Area of Science:
- Gastroenterology
- Oncology
- Endoscopic Surgery
Context:
- Endoscopic mucosal resection (EMR) is a key technique for early gastric cancer treatment.
- Expanding EMR indications requires understanding recurrence patterns and management strategies.
Purpose:
- To evaluate recurrence rates associated with different EMR resection methods (whole-block vs. partial).
- To analyze the management and timing of recurrent gastric cancer after EMR.
- To identify challenges in managing submucosal invasion diagnosed post-EMR.
Summary:
- Analysis of 389 early gastric cancer lesions showed a 15.1% recurrence rate with whole-block resection versus 8.0% with partial resection, highlighting the importance of partial resection with marking for complete tumor removal.
- Recurrent cancers were predominantly diagnosed within one year post-EMR (80.5%), necessitating vigilant follow-up. Treatment options included re-EMR (26 cases) and surgery (15 cases).
- Optimal management strategies for submucosal invasive gastric cancer diagnosed after EMR remain an area for further investigation.
Impact:
- Partial resection techniques in EMR can significantly lower recurrence rates for early gastric cancer.
- Early detection and prompt treatment of recurrent gastric cancer post-EMR improve patient outcomes.
- Further research is needed to refine EMR protocols for managing submucosal gastric cancer.
