乳腺癌腋窝淋巴结超声弹性评分与转移的相关性

Correlation of ultrasonic elastography with axillary lymph node metastasis in breast cancer

目的:探讨乳腺癌腋窝淋巴结超声弹性评分与淋巴结转移的相关性。方法:选取2012年12月至2016年5月在本院胃肠腺体外科行手术治疗的乳腺癌患者173例,应用超声弹性成像对患者同侧173枚腋窝淋巴结进行检测分析。采用Choi J J四分法标准对淋巴结进行超声弹性评分。分析弹性评分与淋巴结转移的相关性,比较不同弹性评分组间的转移率差异。结果:超声弹性评分与乳腺癌腋窝淋巴结转移呈正相关关系(r=0.552,P<0.01)。弹性评分1~4分淋巴结转移率分别为21.05%、36.96%、63.16%、92.16%。不同超声弹性评分腋窝淋巴结转移率两两组间比较:评分1分与3分、1分与4分、2分与3分、2分与4分、3分与4分转移率差异有统计学意义(P<0.05)。结论:超声弹性成像可以评估腋窝淋巴结硬度,为临床判断乳腺癌腋窝淋巴结转移提供依据。

Objective： To explore the relationship between the ultrasonic elastography scores and axillary lymph node metastasis in breast cancer. Methods： Ipsilateral axillary lymph nodes in patients with breast cancer （n= 173） were examined by ultrasonic elastography. Elastogrphic images were given scores of 1 to 4 according to Choi J J criteria. The correlation between elasticity scores and lymph node metastasis was analyzed. Metastatic rate among groups of different scores was compared. Results： There was positive correlation between the elas- togrphic scores and axillary lymph node metastasis （r=0. 552, P〈0. 01 ）. The metastatic rate in score 1 to 4 was 21.05%, 36. 96%, 63. 16% and 92. 16%, respectively. There was significant difference among groups of dif- ferent scores in axillary lymph nodes metastatic rate （P〈0. 05）. Conclusion： Ultrasonic elastography could provide information about axillary lymph node metastasis in breast cancer.
