目的探讨甲状腺影像报告及数据系统(TI-RADS)超声指标与肿瘤生物学行为的相关性。方法将手术病理证实的103例甲状腺癌患者,共计108枚病灶的TI-RADS超声指标与肿瘤侵犯包膜或包膜外周围组织及淋巴结转移进行相关性分析。结果 (1)108枚病灶中颈部淋巴结转移56枚;淋巴结未转移52枚;癌组织侵犯包膜或侵及包膜外组织38枚;癌组织局限于腺体内70枚。(2)单因素和Logistic回归分析显示甲状腺癌≥2cm、结节内微钙化灶发生颈部淋巴结转移增多(P<0.05),以结节内微钙化灶预测更有价值。(3)单因素分析显示病灶≥2cm对预测甲状腺癌包膜或包膜外侵犯有较高价值(P<0.05)。结论 TI-RADS超声指标中结节大小和微钙化灶与肿瘤生物学行为具有一定的相关性,可根据甲状腺癌的超声表现初步预测其预后。
Objective To investigate the correlation between thyroid imaging report and data system (TI-RADS) and tumor biological behavior. Methods Tissue pathology confirmed the 103 cases of thyroid cancer patients, a total of 108 lesions TI-RADS ultrasound and tumor invasion or peritumoral tissue and lymph node metastasis correlation analysis. Results (1) There were 56 cervical lymph node metastases in 108 lesions, 52 non-metastatic lymph nodes, 38 invaded or invading the cancerous tissues, and 70 in the gland. (2) The single factor and Logistic regression analysis showed that thyroid cancer ≥2cm, cervical lymph node metastasis increased in nodular micro-calcification (P <0.05), and nodular micro-calcification was more valuable. (3) Univariate analysis showed that lesions ≥2cm had higher value in predicting the invasion of extranodal or extracapsular thyroid carcinoma (P <0.05). Conclusion TI-RADS ultrasound in nodular size and micro-calcification foci and tumor biological behavior has a certain correlation, according to the thyroid cancer ultrasound performance of the preliminary prediction of its prognosis.
