经乳房切除切口鉴别乳腺癌前哨淋巴结的价值

目的　探讨经乳房切除切口鉴别前哨淋巴结 (SLN)的价值及预测腋窝淋巴结状态的准确性。方法　按接受手术的先后顺序将 72例病人分为经乳房切除切口组 (B组 ,36例 )和腋窝切口组 (A组 ,36例 ) ,采用专利蓝 (Patentblueviolet)癌周注射鉴别乳腺癌前哨淋巴结。结果　SLN鉴别成功率为 83% ( 60 /72 ) ,SLN有转移的 1 8例中 ,唯一转移者 6例 ( 33 3% ) ,B组鉴别成功率 94% ( 34/36) ,预测腋淋巴结的准确性 1 0 0 % ;A组鉴别成功率为 72 % ( 2 6/36) ,预测液淋巴结的准确性为 1 0 0 %。结论　采用蓝染剂经乳房切除切口 ,比腋窝切口更能精确地鉴别前哨淋巴结 ,提高预测腋窝淋巴结状态的准确性。

Identifying sentinel lymph node in breast carcinoma through incisions of mastectomy

Objective To optimize the method of sentinel node identification and observe the influence of different incisions of sentinel node biopsy in breast cancer. Methods Sentinel node in 72 unselected patients with breast carcinoma was identified by using blue dye tracer injection. Of these, sentinel nodes were identified in 36 patients by an axillary lymphadenectomy incision(method A), and the rest were identified by an incision of mastectmoy(method B).Results Sentinel nodes were identified in 60 patients(83%) and 18 patients had metastases in sentinel node. Of these 18, 6(33%)had no other involved axillary status in these 60 patients. Identification rates of method A and B were 72%(26/36) and 94%(34/36), respectively ( P <0 05).Conclusion Sentinel node biopsy could be an accurate predictor of axillary status. The method has higher identification rate and is worth for further study.
