Abstrakt: ABSTRACT: Background: The Bethesda System for Reporting Thyroid Cytopathology (TBSRTC) aims to standardize the terminology and morphologic criteria associated with thyroid fine-needle aspiration cytology (FNAC) results while also providing corresponding risk assessments for malignancy. contributing to more consistent and standardized reporting of thyroid nodules and aiding clinicians in making informed decisions. Since then, it has been undergoing revisions and updates to further improve its utility and accuracy. Materials and Methods: This is a retrospective study conducted at a tertiary care center. All patients with a history of thyroid gland swelling who had previously undergone FNA were included. The procedure included cytopathologists performing FNAC for all cases of midline neck swelling. Demographic and histopathology data were correlated with the cytological diagnosis. Results: We included 288 cases. Of those, 234 (81.3%) were female and 54 (18.8%) were male. The presentation age range was 18–91 years. The most reported category was benign, which constituted 30.9% of the cases followed by malignancy (27.1%). As for thyroid lesions, papillary carcinoma was the most prevalent (43.6%). The correlation on cyto-histopathology was presented in every diagnostic category, showing high heterogeneity in diagnostic specificity and sensitivity. The overall diagnostic specificity and sensitivity were 56.05% (95% confidence interval [CI]: 47.92–63.95%) and 80.92% (95% CI: 73.13–87.25%), respectively. Positive and negative predictive values were 60.57% and 77.88%, respectively. Conclusion: Our data suggests that the TBSRTC system promotes similar sensitivity and specificity to those reported elsewhere. It standardizes reporting and improves communication between cytopathologists and clinicians. [ABSTRACT FROM AUTHOR]
