| 目的 探讨超声诊断乳腺癌腋窝淋巴结(ALN)转移的应用价值。方法 对101例乳腺癌、超声检查显示有ALN的患者进行灰阶超声(US)上淋巴结长短比(L/S)和结构、彩色多普勒超声(CDFI)上血流分布状态的分析。结果 75.0％的转移性淋巴结L/S≤2,20.8％的非转移性淋巴结L/S≤2 (P=0.000)。转移性淋巴结呈皮质偏心增厚型达58.4％,向心增厚型及狭窄型各占20.8％,未见无淋巴门型;非转移性淋巴结呈皮质狭窄型达71.7％,向心增厚型28.3％,未见偏心增厚型和无淋巴门型(P=0.000)。转移性淋巴结血流分布状态呈周边型者60.4％,而非转移性淋巴结呈淋巴门型者73.6％(P=0.000)。以L/S≤2、偏心增厚型皮质、周边型血流作为转移性的标准,敏感性为91.3％,特异性为89.1％。结论 超声诊断有助于判断乳腺癌ALN转移。 |

| Objective To evaluate the value of ultrasonography in diagnosis of axillary lymph node (ALN) metastasis in breast cancer. Methods ALN in 101 patients with breast cancer were performed using gray-scale ultrasonography (US) and color Doppler flow imaging (CDFI). The long-short axis ratio (L/S), structure, flow pattern of ALN were studied. Results L/S≤2 was shown in 75.0％ of metastatic ALN and in 20.8％ of non-metastatic ALN (P=0.000). The eccentric thickening of the cortical zone of metastatic ALN was seen more often (58.4%) than both the centric thickening (20.8％) and the thinning of cortices (20.8％), however, the hilar disappearance was not found in our study. In non-metastatic ALN, the thinning of cortices was found more often (71.7%) than the centric thickening (28.3%), while the eccentric thickening and the disappeared hilum were not found (P=0.000). The 60.4% of metastatic ALN had peripheral flow, while 73.6％ of non-metastatic ALN had hilar flow. The sensitivity and specificity of ultrasonography was 91.3％ and 89.1％,respectively, based on the criteria of L/S≤2, eccentric cortical thickening and peripheral flow. Conclusion Ultrasonography can be useful for diagnosis of ALN metastasis in breast cancer. |
