Classifying the Thyroid Lesions on FNAC According to TBSRTC with Cytohistopathological Correlation

The objective of this prospective study was to analyze the thyroid cytology smears by The Bethesda System for Reporting Thyroid Cytopathology (TBSRTC), to analyze cytological features, and to correlate the cytopathology with its histopathology. Stastical analysis was done. Possible reasons for false positive and false negative results were discussed. Out of 103 fine needle aspirations (FNA) of thyroid nodules, 11.7 % nondiagnostic/unsatisfactory (ND/UNS), 20.3 % benign, 10.7 % atypia of undetermined significance/follicular lesion of undetermined significance (AUS/FLUS), 9.7 %, follicular neoplasm/suspicious of a follicular neoplasm (FN/SFN), 11.7 % suspicious for malignancy (SFM), and 35.9 % malignant. So, it was concluded that TBSRTC is not only useful method for standardization the reporting of thyroid cytopathology but also provides clear management guidelines to clinicians whether to go for follow-up FNA or to do surgery. Thus, unnecessary surgery will be avoided.
