Extragastric metastasis of early gastric cancer after endoscopic submucosal dissection with lymphovascular invasion and negative resected margins
[post]
2022
unpublished
Background: Lymphovascular invasion is a criterion for noncurative resection in patients who have undergone endoscopic submucosal dissection (ESD) for early gastric cancer (EGC). We aimed to determine the rate of extragastric metastasis (EGM) and identify predictors of EGM in patients with negative resected margins (R0 resection) and lymphovascular invasion in their post-ESD pathology.Methods: Among 2,983 consecutive patients, 110 were treated with ESD with follow-up pathology of R0 resection
