Background: The Bethesda System for Reporting Thyroid Cytopathology (BSRTC) is a standardized reporting system for classifying thyroid fine-needle aspiration results comprising of 6 diagnostic categories with unique risks of malignancy and recommendations for clinical management. Our objective was to report our past 4-year experience with the BSRTC, review its distribution and evaluate its efficiency based on the cytologic-histologic correlation.
Design: A total of 12,930 thyroid nodules undergoing FNA were examined at our institution between January 2008 and December 2011. All FNAs were classified prospectively into unsatisfactory, benign, FLUS/AUS (follicular lesions or atypia of undetermined significance), follicular neoplasm (FN), suspicious for malignancy, or positive for malignancy. The Cyto-histologic correlation was recorded.
Results: Table 1 summarizes the diagnostic frequencies.
