Abstract;To clarify the risk factors for lymph node metastasis of submucosal invasive gastric cancer treated by endoscopic mucosal resection (EMR), we investigated the histopathologic findings of 194 surgically resected submucosal cancers. As for the histologic types, we reclassified these cancers according to the dominant histologic types within the mucosa. In the result, logistic regression analysis showed that the covariants which could predict lymph node metastasis were 1) papillary adenocarcinoma, 2) histologic heterogeneity in the submucosa, 3) lymphatic invasion. There were no lymph node metastasis and no abovementioned risk factors in lesions of differentiated submucosal cancers (tub1 or tub2) measuring 40mm or less in size with less than 500.MU.m invasion and measuring 20mm or less in size with less than 1000.MU.m invasion. Furthermore, tub1 or tub2 lesions with INF.ALPHA. showed lower lymph node metastasis significantly, suggesting that these risk factors would be useful for decision of EMR indication in borderline lesions. And we considered that to diagnose submucosal histological findings precisely, an enblock resection method should be performed. (author abst.)
