混合型早期胃癌的诊治研究进展

Research progress in diagnosis and treatment of mixed-type early gastric cancer

随着内镜技术的发展,内镜下黏膜下剥离术已广泛应用于无淋巴结转移的早期胃癌。但是临床上早期胃癌患者内镜下黏膜下剥离术标本的中常发现分化和未分化混合成分,定义为混合型早期胃癌。近年来研究发现,混合型早期胃癌较纯型早期胃癌有更强的侵袭性,更高的淋巴结转移发生率,有学者提出混合型早期胃癌患者应谨慎选择内镜下黏膜下剥离术。文章就近年来混合型早期胃癌的研究进展做一综述。

With the evolution of endoscopy,endoscopic submucosal dissection has been widely used in early gastric cancer without lymph node metastasis.However,mixed components of differentiated and undifferentiated components are often found in endoscopic submucosal dissection specimens of patients with early gastric cancer,which is defined as mixed-type early gastric cancer.In recent years,studies have found that mixed early gastric cancer is more aggressive and has a higher incidence of lymph node metastasis compared with pure early gastric cancer.Some scholars have proposed that patients with mixed early gastric cancer should be carefully treated by endoscopic submucosal dissection.This article reviews the recent research progress of mixed early gastric cancer.
