彩色多普勒超声对乳腺癌腋窝淋巴结转移的诊断价值

Diagnostic value of color Doppler ultrasonography on axillary lymph node metastasis in breast carcinoma

目的:评价彩色多普勒超声与临床触诊诊断乳腺癌腋窝淋巴结转移的灵敏度、特异度和准确度性。方法:应用双盲法对53例(55侧)行乳腺癌根治术患者的术前触诊、超声检查及术后病理检查进行对比分析。结果:55侧中,病理证实41侧有淋巴结转移,临床触诊和超声检出侧分别为35侧和39侧,触诊的灵敏度、特异度、诊断符合率分别为68.3%、50.0%、63.6%,超声则分别为87.8%、78.6%、85.5%,两组间的灵敏度及诊断符合率差异有统计学意义(P<0.05或<0.01),特异度则差异无统计学意义(P>0.05)。结论:超声检查腋窝淋巴结的灵敏度及诊断符合率均高于触诊,可作为诊断淋巴结转移的常规检查项目。

Objective： To compare the accuracy of color Doppler ultrasonography （CDU） with palpation in the diagnosis of axillary nodal metastasis in breast cancer. Methods： Preoperative CDU and palpation and postoperative histopathology were performed on 55 axlilac of 53 patients undergoing radical surgery for breast cancer. Results： Of the 55 axillae, there were 41 metastatic lymph nodes by pathological examination, 35 by palpation, and 39 by CDU. The sensitivity, specificity, and diagnostic accordance rate （DCR） were 68. 3% ,50. 0% and 63.6% in palpation, and 87.8%, 78. 6% and 85.5% in CDU; there were significant differences in the sensitivity and DCR between the palpation and CDU （P〈0.05-0. 01）. Conclusion： CDU has the advantages of high sensitivity and DCR over the palpation, and may be served as a routine examination in the diagnosis of axillary nodal metastasis in breast cancer.
