Abstract
Purpose: Fine Needle Aspiration
(FNA) is the gold standard for assessment of thyroid nodules, with the Bethesda
System for Reporting Thyroid Cytopathology (TBSRTC) used to predict the
malignancy risk of these nodules. Our aim was to evaluate the diagnostic
utility of the TBSRTC for a Saudi population, by comparing the malignancy risk
based on histopathology to FNA-based diagnosis of each of the TBSRTC categories
and to previously published malignancy risk in other population.
Materials and Methods:
This was a retrospective study of the data of 241 patients who underwent FNA
assessment of thyroid nodules and surgical resection with histopathology at
John Hopkins Aramco Healthcare, Dhahran, Saudi Arabia, between January 2016 and
December 2019.
Results: The malignancy risk for each of the TBSRTC
categories was as follows: non-diagnostic, 25%, benign; 5.74%; atypia of
undetermined significance, 37%; suspicious for follicular neoplasm, 38%;
suspicious for malignancy, 100%; and malignant, 95%. Our finding was comparable
to previously published malignancy risks, except for a higher rate of
malignancy in the benign category at 18% compared to 0-3%.
Conclusion: Our findings
validate the diagnostic reproducibility of the TBSRTC for a Saudi population,
with the risk of malignancy confirmed by histopathological assessment being
consistent with those previously reported for other populations.
