目的 :验证乳腺癌前哨淋巴结定位和活检技术的可行性和前哨淋巴结的组织学状况能否准确预告腋淋巴结的状况。方法 :本研究使用专利蓝 ,对 33例乳腺癌患者进行了术中及术后前哨淋巴结定位和活检术。结果 :30例 (91% )找到前哨淋巴结 ,前哨淋巴结预告腋淋巴结的准确率为 96 .7% ,假阴性 1例。结论 :本研究结果证实 ,乳腺癌前哨淋巴结定位和活检技术是可行的 ,前哨淋巴结的组织学特征能够准确反映腋淋巴结的状况。我们相信在将来治疗腋淋巴结阴性的乳腺癌中 ,这一技术可以免除患者接受不必要的腋淋巴结清扫术。
Objective: To verify the feasibility of the sentinel lymph node localization and biopsy technique and the histologic status of sentinel lymph nodes to accurately predict the status of axillary lymph nodes. METHODS: In this study, 33 patients with breast cancer were treated with patent blue, and the positioning and biopsy of sentinel lymph nodes were performed during and after surgery. Results : Sentinel lymph nodes were found in 30 cases (91%). The accuracy of the sentinel lymph nodes was 96.7% in the axillary lymph nodes and false negative in 1 case. Conclusion : This study confirms that the sentinel lymph node localization and biopsy technique is feasible for breast cancer. The histologic features of sentinel lymph nodes can accurately reflect the status of axillary lymph nodes. We believe that in the future in the treatment of axillary lymph node-negative breast cancer, this technique can save patients from unnecessary axillary lymph node dissection.
