前哨淋巴结检测在非小细胞肺癌纵隔淋巴结清扫方式中的应用现状

Application status quo of sentinel lymph node detection in mediastinai lymphadenectomy of non-small cell lung cancer

非小细胞肺癌（NSCLC）手术淋巴结清扫的方式与患者的预后密切相关，精确评估区域淋巴结的转移及淋巴结清扫术的选择是患者预后的重要影响因素。尽早发现局部淋巴结微转移灶对肿瘤的临床分期以及据此制定合理的治疗方案有极重要的意义。前哨淋巴结（SLN）活检术在肿瘤隐匿性转移检测及分期方面的潜在价值引起了越来越多研究者的注意。

In surgical operation of the non-small cell lung cancer （NSCLC）, the resection of lymph node involvement is highly correlated with the prognosis of NSCLC patients. The precise estimation of localized lymph node involved and the determination of relevant pattern of lymphadenectomy are the significant predictors for the prognosis and postoperative treatment in NSCLC patients. Therefore to identify the lymph node metastasis earlier has more important significance for tumor clinical staging and making therapeutic schedule. In recent years, the value of sentinel lymph node （SEN）has attracted more and more researchers attention in detecting the occult lymph node micrometastases and surgical staging.
