Use of the thyroid imaging, reporting, and data system (TI-RADS) scoring system for the evaluation of subcentimeter thyroid nodules.

摘要: BACKGROUND The American Thyroid Association (ATA) recommends fine-needle aspiration (FNA) biopsy of nodules measuring >1.5 cm with low-suspicion sonographic patterns or >1.0 cm high/intermediate-suspicion features. Routine <1 cm is not recommended. However, despite these recommendations, subcentimeter are often referred for FNA biopsy. METHODS This was a retrospective chart review consecutive thyroid FNAs during an 18-month period (1157 patients, 1491 nodules, 2016-2017) to evaluate age, sex, medical history, diagnoses, and follow-up. Radiographic information used identify 61 (4%) from 57 patients. Ultrasound studies were re-evaluated using criteria according the College Radiology Imaging, Reporting, Data System (TI-RADS). RESULTS Reported reasons included larger companion nodule (44%), personal family history cancer (26%), suspicious sonogram, including calcification and/or irregular contours (16%). diagnoses included: 69% benign (42 nodules), 10% papillary carcinoma (PTC) (6 15% atypia undetermined significance/follicular lesion significance (AUS/FLUS) (9 nodules). Seven percent unsatisfactory/nondiagnostic (4 nodules) compared 3% nondiagnostic rate all sized nodules. Fifty-one had ultrasound available re-review TI-RADS scoring system.
