目的：分析单个SLN阳性保腋窝在乳腺癌改良根治术中的应用可行性。方法收集来我科就诊的临床诊断为乳腺癌且伴随单个SLN阳性的患者45例，SLN阴性的患者45例。两组患者均行腋窝淋巴结清扫。对比两者NSLN阳性率的差异。结果单个SLN阳性组的NSLN阳性3例，阳性率为6.7%（3/45）。 SLN阴性组的NSLN阳性率为2.2%（1/45）。两组NSLN阳性率差异无统计学意义（χ2=0.26，P＞0.05）。结论单个SLN阳性患者与SLN阴性患者NSLN阳性率无差异，单个SLN阳性保腋窝在乳腺癌改良根治术中的应用有可行性。

Objective To analyze the application of the feasibility study on omitting axillary lymph node dissection with single sentinel lymph node metastasis in modify radical mastectomy. Methods 45 patients with single sentinel lymph node metastasis and 45 patients without sentinel lymph node metastasis diagnosed as breast cancer in our department were selected. All the patients were handled with axillary lymph node dissection after sentinel lymph node biopsy. The positive rate of non-sen-tinel lymph node in these two groups were compared. Results Singel sentinel lymph node positive group had 3 non-sentinel lymph node positive patients (6.7%,3/45), but one (2.2%,1/45) in negative sentinel lymph node group. There was no statisti-cal difference between the two groups (χ2=0.26,P>0.05). Conclusion There was no significant difference in the positive rate of non-sentinel lymph node between the two groups with single sentinel lymph node metastasis and no sentinel lymph node metastasis. It's possible that axillary lymph node dissection can be omitted in patients with single sentinel lymph node metastasis.
