Abstract
WITHDRAWN: Indication for endoscopic treatment based on the risk of lymph node metastasis in patients with ulcerative-type early gastric cancer
Highlights
Endoscopic submucosal dissection (ESD) is an effective alternative to surgical treatment for patients with early gastric cancer (EGC) and minimal risks of developing regional lymph node metastasis (LNM) [1]
Among patients with minute submucosal invasion and no lymphovascular invasion, LNM was only observed in patients with tumor sizes > 2.0 cm
Because the LNM risks are negligible, curative endoscopic submucosal dissection (ESD) could be considered in patients with ulcerative EGC that is confined to the mucosa and histologically differentiated, irrespective of tumor size
Summary
The overall LNM rate was 15.1%, 0% for mucosa-confined lesions, and 28.2% for submucosa-infiltrating lesions. Only lymphovascular invasion (P < 0.001) was significantly associated with LNM. Among patients with minute submucosal invasion and no lymphovascular invasion, LNM was only observed in patients with tumor sizes > 2.0 cm
