Abstract

Background: Ultrasound and cytology are the two major diagnostic modalities employed for the preoperative evaluation of thyroid lesions. Ultrasound thyroid imaging reporting and data systems (TI-RADS) have been proposed for risk stratification of thyroid nodules. The Bethesda system for reporting thyroid cytopathology (TBSRTC) by using six diagnostic categories with a stratified risk of malignancy (ROM) in each category is employed for unambiguous cytology reporting of thyroid lesions. Our objective is to study the association between TI-RADS ultrasound categories and Bethesda cytology categories in thyroid lesions and to find their diagnostic accuracy as compared with histopathological diagnosis wherever possible.

Methods: This is a prospective observational study in which a total of 107 patients were studied. Thyroid ultrasound was scored according to TI-RADS classification. A pathologist screened ultrasound-guided FNAC smear, and reporting was done using the Bethesda system of reporting. The pathologist was blinded for the TI-RADS report.

Results: Among all the 107 cases, the patients' age ranged from 8 to 70 years with a mean age of 41.67 ± 14.41 years. The men: women ratio was 1:5. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of TI-RADS were 50%, 95.24%, 88.89%, and 71.43%, respectively, with a diagnostic accuracy of 75.68%, while the sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of Bethesda were 81.25%, 85.71%, 81. 25%, and 85.71%, respectively, as compared with the histopathological diagnosis. TI-RADS ultrasound categories and Bethesda cytology categories were correlated in 88% of cases.

Conclusions: TI-RADS and TBSRTC classification systems are specific diagnostic modalities in thyroid lesions. They are correlated in the majority of cases.

甲状腺病变TI-RADS超声分类与BETHESDA细胞学分类的关系。
背景:超声和细胞学是术前评估甲状腺病变的两种主要诊断方式。甲状腺超声成像报告和数据系统(TI-RADS)已被提出用于甲状腺结节的风险分层。Bethesda系统用于报告甲状腺细胞病理学(TBSRTC),通过使用六个诊断类别,每个类别中有恶性肿瘤(ROM)的分层风险,用于明确的甲状腺病变细胞学报告。我们的目的是研究甲状腺病变中TI-RADS超声分类与Bethesda细胞学分类之间的关系,并尽可能将其诊断准确性与组织病理学诊断进行比较。方法:这是一项前瞻性观察研究,共研究了107例患者。甲状腺超声按TI-RADS分级评分。病理学家筛选超声引导的FNAC涂片,并使用Bethesda报告系统进行报告。病理学家对TI-RADS报告进行盲检。结果:107例患者年龄8 ~ 70岁,平均年龄41.67±14.41岁。男女比例为1:5。TI-RADS的敏感性、特异性、阳性预测值(PPV)、阴性预测值(NPV)分别为50%、95.24%、88.89%、71.43%,诊断准确率为75.68%,而Bethesda的敏感性、特异性、阳性预测值(PPV)、阴性预测值(NPV)分别为81.25%、85.71%、81。与组织病理诊断相比,分别为25%和85.71%。88%的病例TI-RADS超声分类与Bethesda细胞学分类相关。结论:TI-RADS和TBSRTC分类系统是甲状腺病变的特异性诊断方式。在大多数情况下,它们是相关的。
