Analysis of associated factors of lymph node metastasis in intramucosal early gastric cancer / 中华胃肠外科杂志

<p><b>OBJECTIVE</b>To analyze the associated predictive factors of lymph node metastasis in intramucosal early gastric cancer, and to provide reference for individualized treatment protocol.</p><p><b>METHODS</b>Clinical data of 498 patients who were pathologically confirmed to be intramucosal early gastric cancer after radical resection of gastric cancer were retrospectively reviewed. Univariate and multivariate analyses were applied to evaluate the associated factors.</p><p><b>RESULTS</b>Forty-three out of 498 patients (8.6%) had lymph node metastasis. Tumor size (HR=1.525, 95%CI:1.040-2.236), depth of invasion (HR=1.656, 95%CI:1.158-2.368) and histological type (HR=8.149, 95%CI:1.770-37.513) were the independent risk factors for lymph node metastasis in intramucosal early gastric cancer.</p><p><b>CONCLUSIONS</b>Prediction and therapeutic guidance for lymph node metastasis in intramucosal early gastric cancer can be carried out according to clinicopathological risk factors.</p>

Feasibility of endoscopic resection for gastric gastrointestinal stromal tumor / 中华胃肠外科杂志

In recent years, with the development of digestive endoscopy, endoscopic submucosal dissection(ESD) and its derived techniques including endoscopic submucosal excavation(ESE), submucosal tunnelling endoscopic resection(STER) and laparoscopic endoscopic combined surgery(LECS), can cure most of the gastric gastrointestinal stromal tumor(GIST). This article reviews the indication, method and evaluation of endoscopic resection for gastric GIST.
