Indication for endoscopic treatment based on the risk of lymph node metastasis in patients with undifferentiated early gastric cancer.
CONCLUSIONS: LNM-related risk factors were tumor larger than 2.0 cm, submucosal invasion, and the presence of LVI in UD-type EGC. ESD alone may be sufficient treatment for the intramucosal UD-type EGC that is smaller than 1.0 cm in size. When endoscopically resected specimens show unexpectedly larger tumor size, unexpected submucosal and LVI than that determined at pre-ESD endoscopic diagnosis, an additional gastrectomy with lymphadenectomy should be considered.
