Application of the Bethesda System for Reporting Thyroid Cytopathology in the Eastern Province of Saudi Arabia: Phase I Pilot Retrospective Analysis

We analyzed and evaluated our adequacy rate and the classification of our thyroid aspirates using the Bethesda System for Reporting Thyroid Cytopathology (BSRTC). All thyroid fine needle aspirates that were collected or referred to our institution were reviewed and reclassified according to the BSRTC. The results were tabulated and analyzed. Those with histological resection were correlated with our revised cytopathological evaluation using the BSRTC. A total of 205 thyroid aspirates from 186 patients were reviewed. There were 149 females (80%) and 37 males (20%) ranging in age from 23 to 81 (average age 48) years. All slides were reclassified using the BSRTC. The previous interpretations were not consistent with any apparent standards. The nondiagnostic rate was found to be 22%. Five cases were considered false negative and were upgraded to a more serious category with higher risk of malignancy. The high unsatisfactory rates can be reduced by an adequacy interpretation at the time of the procedure. The risk of malignancy in our cohort increased with each increase in the BSRTC category (I-VI). Communication about and awareness of the BSRTC and its implications by all our clinicians is a prime target of this study and is still work in progress. Hopefully, this study will increase the awareness of the BSRTC and its intended benefits in our region. (C) 2013 S. Karger AG, Basel
