分析了１１６例甲状腺“冷结节”ＲＮＡ。血供丰富的单发结节中，甲状腺癌占３７．０％，甲状腺腺瘤５９．３％，结节性甲肿３．７％；血供丰富的多发结节及有血供的单发结节癌的发生率分别为１６．７％和４．３％；有血供结节及无血供结节均为良性病变。恶性结节血供丰富的阳性率为９１．７％，高于甲状腺腺瘤（２６．２％）和结节性甲肿（１５．８％），差异有极显著性意义。甲状腺ＲＮＡ鉴别“冷结节”良恶性的灵敏度为９１．７％、特异性７８．８％、准确性８０．２％，与Ｂ超、触诊无显著性差异，但三者结合可提高诊断的特异性和准确性。
116 cases of thyroid cold nodule RNA were analyzed. In single solitary nodules rich in blood supply, thyroid cancer accounted for 37.0%, thyroid adenomas 59.3%, nodular masses 3.7%; multiple nodules with abundant blood supply and single blood supply The incidence of nodular cancer was 16.7% and 4.3%, respectively; blood supply nodules and no blood supply nodules were benign lesions. The positive rate of abundant blood supply in malignant nodules was 91.7%, which was higher than that of thyroid adenomas (26.2%) and nodular masses (15.8%). The difference was extremely significant. The sensitivity of thyroid RNA in the identification of benign and malignant “cold nodules” was 91.7%, specificity 78.8%, and accuracy 80.2%. There was no significant difference between B-ultrasound and palpation, but the combination of the three could improve the diagnosis. The specificity and accuracy.
