乳腺癌非哨兵淋巴结转移的预测

目的探讨乳腺癌非哨兵淋巴结（non-sentinel lymph node,NSN）转移预测的临床因素。方法回顾该科近2年来230例乳腺癌患者行哨兵淋巴结活检（sentinel lymph node biopsy,SLNB）,后行腋窝淋巴结清扫术（axillary lymph node dissection,ALND）。有哨兵淋巴结（sentinel lymph node,SN）转移的94例,分析其中非哨兵淋巴结（NSN）转移的患者与临床因素的关系。结果SN有转移的94例患者,67例（72.27%）有NSN转移;原发肿瘤的大小（P〈0.01）,SN转移的个数（P〈0.05）,组织学病理分级（P〈0.05）是预测NSN转移的指标。将3个因素联合起来预测NSN转移可达到94.12%（16/17）（P〉0.05）;而患者年龄,肿瘤生长位置、病理类型、ER、PR、C-erbB-2（Her-2/neu）、P53、nm23表达与否对NSN转移预测无统计学意义（P〉0.05）。结论乳腺癌原发病灶的大小,SN转移的个数,组织学病理分级或3个因素联合分析对预测NSN的转移有重要意义。

Prediction of metastases to non-sentinel lymph node in invasive breast cancer

[Objective] To investigate the predictive factors of non-sentinel lymph node (NSN) metastases in women with invasive breast cancer. [Methods] Aprospective data was analyzed and enrolled patients (n = 230) who underwent sentinel lymph node biopsy (SLNB) follow axillary lymph node dissection (ALND) for invasive breast cancer in the recent 2 years. 90 (40.86%) patients had one or more positive SLNs and were analyzed to determine factors that predicted additional positive axillary nodes. [Results] Of the 94 pat...
