A PROSPECTIVE STUDY FOR REPORTING THYROID FINE NEEDLE ASPIRATES BY THE BETHESDA SYSTEM WITH HISTOLOGICAL CORRELATION

Abstract

BACKGROUND: To reduce ambiguity in diagnostic terminology in thyroid ne needle aspiration cytology (FNAC),The Bethesda System for Reporting Thyroid cytopathology (TBSRTC) system is a universal reporting system for standardization and could help in assessing the prognosis by estimating the malignant potential of each category . AIMS:The aim of the study is cytodiagnosis of thyroid ne needle aspirates and uniformity in the reporting as per Bethesda system. Histological examination was also conducted so that a correlation between cytodiagnosis and histopathological examination could be made. MATERIALS & METHODS: This prospective study done on patients (125) presenting with thyroid swelling and advised for FNAC by clinicians, diagnosed according to the Bethesda system of thyroid cytopathology reporting . Then, correlation with histopathological report done in cases(55) in which surgery were done. RESULTS:The distribution of cases were as follows: 2 nondiagnostic(1.6%),89 cases(71.2%) were classied as benign, 6 cases (4.8%) were classied as atypia of undetermined signicance /follicular lesion of undetermined signicance/AFLUS, 7 cases(5.6%) were classied as follicular neoplasm/SFN, 3 cases( 2.4% ) were classied as suspicious, and 18 cases( 14.4%) were classied as malignant.In our study, rates of malignancy for each category are : nondiagnostic-0%, benign-4.76%, AFLUS- 16.67% ,SFN-28.57%, suspicious- 66.67% and malignant-94.12%.
