چکیده
Abstract Aim Fine Needle Aspiration Cytology (FNAC) remains the primary determinant of management options for a patient with U3-5 thyroid nodule. There is significant variation in risk malignancy (ROM) between different centres, possibly reflecting degree specialist reporting and interpretation RCPath guidance. The aims this study to report on ROM FNAC categories cytopathology centre. Methods Consecutive results were analysed over 2 years (2017/18), all reported by dedicated cytopathologists suspicious samples peer reviewed. Cases NIFTP/FVPTC classified as Thy4. U-grade was recorded if during ultrasonography. Results regard histology available surgery and/or clinical follow up. 695 from 567 patients. each category was: Thy1(6%); Thy2(1%), Thy3a(13%); Thy3f(11%); Thy4(27%); Thy 5(100%). In addition, 34/86 Thy3a nodules subject repeat FNAC, 19 Thy2, 7 again, 1 Thy3f Thy4 second FNAC. We found that stratification Thy3a-3f-4 U grade did not help stratification. Conclusions Compared recent meta-analysis (Poller et al), we greatly reduced group (27% vs 79%), smaller reductions both 3 groups our specialised reasons will be discussed. descriptor 4 “suspicious malignancy” inaccurate experience. Each centre should use their own figures when advising Repeat lesions leads >20% potentially avoiding surgery.

Thyroid nodules are commonly encountered in clinical practice. Although the overwhelming majority of them turn out to be benign, the small subset of cancerous nodules needs to be accurately identified for optimal and timely surgical management. Fine-needle aspiration has proven to be the most valuable diagnostic modality for pre-operative distinction of benign from malignant nodules. The recent...

BACKGROUND Despite lack of adequate, validated, independently performed clinical studies, several molecular tests are commercially available on the market and are being used on indeterminate thyroid nodules to guide patient-care decisions. METHODS We summarize the current evidence on the role and limitations of molecular tests used in combination with thyroid cytopathology to refine the presu...

Fine-needle aspiration (FNA) is an important test for triaging patients with thyroid nodules. The 2007 National Cancer Institute Thyroid Fine-Needle Aspiration State-of-the-Science Conference helped instigate the recent publication of The Bethesda System for Reporting Thyroid Cytopathology. We reviewed 3,080 thyroid FNA samples and recorded interpretations according to the proposed standardized...

BACKGROUND Cytologically indeterminate thyroid nodules represent a diagnostic and therapeutic challenge. In 2007, the National Cancer Institute recommended The Bethesda System for Reporting Thyroid Cytopathology (TBSRTC) as a means of improving the accuracy of thyroid cytopathology. Our objective was to determine the effect of TBSRTC on thyroidectomy rates and malignancy risk in cytologically i...
