摘要
We undertook a comparative histologic study of early stage carcinoma of the esophagus and stomach, with tumor invasion limited to the submucosa. Here we analyze lymph node metastasis, lymphatic invasion, and vascular invasion. Our study is based on a retrospective review of 77 patients with early stage carcinoma of the esophagus and 192 patients with early stage carcinoma of the stomach treated during the period from 1973 through 1991. The incidence of lymph node metastasis and lymphatic invasion was significantly higher in intramucosal or submucosal esophageal cancer than in intramucosal or submucosal gastric cancer. However, there was no significant difference between intramucosal esophageal cancer and submucosal gastric cancer. The metastatic site of lymph nodes in esophageal cancer tended to be distant from the location of primary tumor compared with lymph nodes invaded by gastric cancer. Lymphatic invasion and vessel invasion between submucosal esophageal cancer and submucosal gastric cancer was statistically significant. From these results, we conclude that intraepithelial or intramucosal esophageal cancer is comparable to early stage carcinoma of the stomach, whereas submucosal esophageal cancer is actually an advanced lesion.
