研究目的:

为了研究建立早期浸润性乳腺癌患者腋窝前哨淋巴结转移风险的预测模型,并进一步通过筛检试验验证低风险且穿刺阴性患者的诊断准确性,最终在术前筛选出可能豁免前哨淋巴结活检的早期乳腺癌患者,以优化临床腋窝管理决策,减少不必要的前哨淋巴结活检。  

Objectives of Study:

To develop a predictive model for assessing the risk of axillary sentinel lymph node metastasis in patients with early invasive breast cancer, and to further validate the diagnostic accuracy of screening tests for low-risk patients with negative puncture results, with the ultimate goal of preoperatively identifying early breast cancer patients who may be exempt from sentinel lymph node biopsy. This approach aims to optimize clinical axillary management decisions and reduce unnecessary sentinel lymph node biopsies.
