Journal Title: Indian Journal of Pathology and Oncology - Year 2018, Vol 5, Issue 4
Abstract
Introduction FNAC is an excellent modality for diagnosis of thyroid lesions because of its simplicity and cost effectiveness Since the introduction of The Bethesda System for Reporting Thyroid Cytopathology TBSRTC in 2007 it has become a standardized convenient and more informative system of thyroid reportingAims 1 To study cytological features of FNAC and categorization according to TBSRTC 2 To assess statistical analysis of FNAC in detecting malignant lesionsSettings and Design This is a crosssectional study carried out in the Pathology Department from January 2015 to December 2017Materials and Methods We interpreted 329 thyroid FNAC and categorized them according to TBSRTC 75 cases are correlated histologicallyStatistical Analysis Accuracy specificity sensitivity and predictive valuesResult Distribution of different categories are as follows Nondiagnosticunsatisfactory NDUNS85 Benign852 Atypia of undetermined significancefollicular lesion of undetermined significance AUSFLUS06 Follicular neoplasmsuspicious for follicular neoplasm FNSFN24 Suspicious for malignancy SFM15 and malignant18 The malignancy risk calculated from histopathological follow up of 75 cases is as follows NDUNS 0 Benign 69 FNSFN 167 SFM 667 and malignant 100 The positive predictive value negative predictive value and accuracy of TBSRTC are 100 931 937 respectivelyConclusion The malignancy risk accuracy specificity and predictive values are consistent with other studies Thus TBSRTC allows more standard reporting specific diagnosis and understanding of terminology between pathologists and cliniciansKeywords FNAC TBSRTC Thyroid
