早期胃癌淋巴结转移评估方法的研究现状

早期胃癌的定义为癌灶仅局限于黏膜层或黏膜下层,无论病灶大小及有无淋巴结转移。研究证实淋巴结转移是早期胃癌的独立预后因素,并且对评估早期胃癌患者的预后以及指导治疗具有重要临床意义。评估早期胃癌淋巴结转移的方法有很多,临床上常常应用CT及超声内镜等影像学检查评估早期胃癌淋巴结转移,此外病理活检、分子标志物及前哨淋巴结示踪活检等方法也在早期胃癌淋巴结转移的评估中占有重要位置,本文就早期胃癌淋巴结转移相关评估方法现状予以综述。

Research status for evaluation methods of lymph node metastasis in the early gastric cancer

Early gastric cancer is defined as cancerous foci that are confined to the mucosa or submucosal layer,regardless of the size of the lesion and the presence or absence of lymph node metastasis.Studies have confirmed that lymph node metastasis is an independent prognostic factor for early gastric cancer,and has important clinical significance for assessing the prognosis of early gastric cancer patients and guiding treatment.There are many methods for assessing lymph node metastasis in the early gastric cancer.CT and ultrasound endoscopy are often used to evaluate lymph node metastasis in the early gastric cancer.In addition,pathological biopsy,molecular markers,and sentinel lymph node tracking biopsy are also used in the early gastric cancer.It plays an important role in the evaluation of this disease.This article reviews the current status of assessment methods for lymph node metastasis in the early gastric cancer.
