胃癌前哨淋巴结示踪的现状与进展

Sentinel lymph node tracing of gastric cancer: current status and progress

早期胃癌患者淋巴结转移率较低,所以对其实施标准胃癌根治术可能造成"过度治疗",影响患者预后。为此,我们需要一种减小侵犯的,提高生存质量的个体化手术,而前哨淋巴结(sentinel lymph node,SLN)导航外科的应用使之成为可能。SLN是指接受肿瘤淋巴回流的第一个/第一组区域淋巴结,最易发生肿瘤淋巴转移。目前,已有很多关于肿瘤SLN示踪作用的研究,包括对传统术中示踪方法的改进、实现术前SLN多模式显像等。本文就胃癌SLN示踪的现状与进展作如下综述。

The incidence of lymph node metastasis is relatively low in patients with early gastric cancer.Hence standard radical resection might be an overtreatment and prognosis might be interfered.Thus minimally invasive and individualized surgery bascd on sentinel lymph node （SLN） navigation should be performed to improve quality of life of patients.SLN is defined as the first one/group lymph node of primary tumor drainage,which is at the highest risk of lymphatic metastasis.Currently,many studies concerning SLN tracing in gastric cancer have been conducted,including the improvement of traditional methods,preoperative SLN multimodality imaging,etc.In this paper,the current status and progress of SLN tracing are reviewed.
