目的探讨超声检查对甲状腺癌颈部转移性淋巴结的诊断价值。方法选取2013年10月至2016年10月间武汉市汉阳医院收治的64例行甲状腺癌手术的患者,采用术前超声检查及手术病理证实,观察淋巴结的分布区域、数目、形态、边界、纵横比、内部回声、内部有无钙化及内部血流情况等。结果超声探及颈部可疑淋巴结共310枚,其中158枚经病理诊断为甲状腺癌颈部转移性淋巴结,152枚为颈部非转移性淋巴结,超声诊断颈部淋巴结转移符合率为51.0%(158/310)。158枚病理诊断颈部转移性淋巴结中超声显示淋巴结内部髓质消失或偏心发生率为83.5%(132/158),淋巴结内部出现微小钙化发生率为45.6%(72/158),淋巴结纵横比>0.55发生率为60.1%(95/158)。152枚病理诊断颈部非转移性淋巴结中超声显示淋巴结内部髓质消失或偏心发生率为13.2%(20/152),淋巴结内部出现微小钙化发生率为13.2%(20/152),淋巴结纵横比>0.55发生率为23.0%(35/152)。上述三个超声特征分布在转移性和非转移性淋巴结组间比较,差异均有统计学意义(均P<0.01)。转移性淋巴结中形态不规则发生率为26.6%(42/158),非转移性淋巴结中形态不规则发生率为19.1%(29/152),两者比较,差异无统计学意义(P>0.05)。结论超声检查对于甲状腺癌转移性颈部淋巴结具有重要诊断价值。
Objective To investigate the diagnostic value of ultrasonography in cervical metastatic lymph nodes of thyroid cancer. Methods Sixty-four patients undergoing thyroid cancer surgery admitted to Hanyang Hospital of Wuhan City from October 2013 to October 2016 were enrolled in this study. Preoperative ultrasonography and pathological examination were performed to observe the distribution, number, morphology, boundary, aspect Than internal echo, internal calcification and internal blood flow situation. Results A total of 310 suspicious lymphadenectomy were found in the ultrasonography. 158 of them were pathologically diagnosed as cervical metastatic lymph nodes and 152 non-metastatic cervical lymph nodes. The coincidence rate of ultrasound diagnosis of cervical lymph node metastasis was 51.0% (158 / 310). 158 pathological diagnosis of cervical metastatic lymph node ultrasound showed that the incidence of internal medial lymph node disappearance or eccentric incidence was 83.5% (132/158), the occurrence of microcalcifications within the lymph node was 45.6% (72/158), lymph node aspect ratio> The incidence of 0.55 was 60.1% (95/158). Fifty-two pathologically diagnosed cervical non-metastatic lymph nodes showed ultrasonography in 13.2% (20/152) cases of disappearance or eccentricity of internal medullary lymph nodes, 13.2% (20/152) in lymph nodes, and lymph node aspect ratio The incidence of> 0.55 was 23.0% (35/152). The distribution of the above three ultrasound features was significantly different between metastatic and non-metastatic lymph nodes (all P <0.01). The incidence of morphological irregularities in metastatic lymph nodes was 26.6% (42/158), and that of non-metastatic lymph nodes was 19.1% (29/152). There was no significant difference between the two groups (P> 0.05 ). Conclusion Ultrasonography has important diagnostic value for metastatic cervical lymph nodes in thyroid cancer.
