摘要/Abstract

摘要： 本研究探讨超声特征诊断甲状腺微小乳头状癌（PTMC）颈部淋巴结转移的价值。采用超声检查PTMC患者70例，其中有颈部淋巴结转移患者年龄、有腺外侵犯、纵切图像纵横比>1.0、横切图像纵横比>1.0、直径≥5 mm、有微小钙化、边界不清楚、结节接触（或侵及）被膜长度/结节周长≥1/4比例明显高于无颈部淋巴结转移患者（P<0.05）。Logistic回归分析显示：年龄、腺外侵犯、纵切图像纵横比>1.0、结节接触（或侵及）被膜长度/结节周长≥1/4和微小钙化是PTMC患者发生颈部淋巴结转移的影响因素（P<0.05）。用影响因素建立的Logistic回归方程的ROC曲线下面积为0.822，P<0.05，诊断颈部淋巴结转移的灵敏性和特异性分别为81.50%和83.00%。超声特征在PTMC颈部淋巴结转移诊断有较好的应用价值。

Abstract: This research to investigate the diagnostic value of ultrasound features in lymph node metastasis of thyroid papillary microcarcinoma (PTMC). Seventy patients with PTMC were detected by ultrasound examination, in which the age, extraglandular invasion, longitudinal image aspect ratio >1.0, transverse image aspect ratio >1.0, diameter ≥ 5 mm, microcalcification, unclear boundary, nodule contact (or invasion) capsule length/nodule perimeter ≥ 1/4 ratio of patients with cervical lymph node metastasis were significantly higher than those without cervical lymph node metastasis Patients with lymph node metastasis (P<0.05). Logistic regression analysis showed that age, extraglandular invasion, aspect ratio of longitudinal image >1.0, nodule contact (or invasion) capsule length/nodule perimeter ≥ 1/4 and microcalcification were the influencing factors of cervical lymph node metastasis in PTMC patients (P<0.05). The area under ROC curve of influencing factors to establish the Logistic regression equation was 0.822 (P<0.05), while the sensitivity and specificity of diagnosis of cervical lymph node metastasis were 81.50% and 83.00%, respectively. The ultrasound features has a good application value in the diagnosis of cervical lymph node metastasis of PTMC.
