N2 - Context.-The current study compares data from our hospital system before and after the 2008 implementation of the Bethesda System for Reporting Thyroid Cytology (BSRTC). Objective.-To show the effects the BSRTC has had on the reporting rates and outcomes for thyroid lesions. Design.-A search for thyroid fine-needle aspiration biopsies (FNABs) was performed for 2002-2005 (before BSRTC) and 2009-2011 (after BSRTC). Diagnostic outcomes were reviewed for cases with available follow-up. Results.-For 2002-2005, cytology reports for 3302 thyroid FNABs were reviewed, and 309 (9.4%) were classified as suspicious. For 2009-2011, cytology reports for 3432 thyroid FNABs were reviewed; 72 (2.1%) were classified as "atypia of undetermined significance or follicular lesion of undetermined significance" (AUS/ FLUS), and 142 (4.1%) were classified as suspicious. Follow-up material was available for 31 AUS/FLUS cases (43.0%), and 6 of these cases (19%) were malignant. Follow-up material was available for 60 cases (42.3%) classified as suspicious, and 23 of these cases (38%) were malignant. Conclusions.-The AUS/FLUS rate of 2.1% at our institution is at the lower range of the ,7% recommended by the BSRTC, and our rate of 19% for risk of malignancy for AUS/FLUS is slightly above the BSRTC recommendation of 5% to 15%. Implementation of the BSRTC did not significantly affect our institution's reporting rates, most likely because an essentially similar classification system was employed before implementation of the BSRTC.
