【摘要】:目的探讨高频超声术前预测甲状腺乳头状癌(PTC)被膜外侵犯(ETE)的临床价值。方法收集经手术治疗的PTC患者116例,共151个结节,回顾性分析其声像图特点,观察结节与甲状腺被膜邻接长度占结节周长百分比(A),分析以A≥1%、A≥25%及A≥50%预测PTC ETE的诊断效能。结果 151个PTC中,手术病理证实59个(59/151,39.07%)有被膜外侵犯(ETE组),92个(92/151,60.93%)无被膜外侵犯(non-ETE组)。超声发现结节位于甲状腺实质内(A0)84个(84/151,55.63%),1%≤A25%、25%≤A50%、A≥50%分别有25个(25/151,16.56%)、15个(15/151,9.93%)、27个(27/151,17.88%)。A≥1%、A≥25%、A≥50%的结节个数在ETE组和non-ETE组比较差异均有统计学意义(P均0.01)。以A=50%为截断值,诊断PTC被膜外侵犯的敏感度、特异度、准确率、阳性预测值、阴性预测值分别为37.29%(22/59)、94.57%(87/92)、72.19%(109/151)、81.48%(22/27)、70.16%(87/124)。结论高频超声可有效预测PTC有无ETE,为术前合理选择手术方式及对患者预后评估提供重要参考信息。
[Abstract]:Objective to evaluate the clinical value of high frequency ultrasonography in predicting extramembranous invasion of thyroid papillary carcinoma (PTC) before operation. Methods A total of 151 nodules were collected from 116 patients with PTC who underwent surgical treatment. The ultrasonographic features of these patients were analyzed retrospectively. To observe the percentage of the adjacent length of the nodule and thyroid capsule to the circumference of the nodule, and to analyze the diagnostic efficacy of A 鈮,
