摘　　要：目的通过应用不同浓度和剂量的锝99标记的硫胶体注射液注射于乳腺癌患者乳晕区真皮内，观察其在乳腺癌前哨淋巴结活检中的作用，为核素法乳腺癌患者前哨淋巴结活检，提供试验依据。方法选取乳腺癌患者，随机分为三组。注射不同浓度和剂量的锝99标记的硫胶体注射液注射于乳腺癌患者乳晕区真皮内。用探测仪探测热点，术中结合探测仪完全切除前哨淋巴结。然后再继续行腋窝淋巴结清扫，把切除组织送病理检查。最后进行比较。结果三组试验中热点出现的时间，最短的为2.0mci，0.2mL组。三组SLN检出在1~3枚之间，各组间差异无统计学意义，准确率为98.1%，假阴性率为5.3%。结论核素法乳腺癌前哨淋巴结活检浓度和剂量对SLN的检出枚数及检出率和假阴率没有影响但对热点出现的时间有影响，但主要是剂量方面的影响，浓度因素不起作用。Abstract： Objective Usingsubareolar versus at different concentration and dose in sentinel lymph node biopsy to study the role of them in the SLNB in breast carcinoma and to provide experimental evidence for the choice of tracing marke of the sentinel lymph node biopsy in breast carcinoma patients. Methods Breast cancer patientswere randomly divided into three groups.Radioactive SLNS were identiifed and removed during operation.Allslns were examined for pathology separately and all patients had axillary lymphadenectomy and routinely pathological examined. Results SLNS Were identiifed and there were no signiifcant difference among different qroups. The average time of SLN being stained,2.0mci/0.2mL was the shortest. Identifying rate was 98.1%and false negative rate was 5.3%. Conclusion Tracing marke of different concentration and dose was no effection at identifying rate and false negative rate whiletracing marke of different concentration and dose effected the time of SLN being stained.
