STUDY ON EVALUATION OF TYPE OF THYROID LESIONS ON FNAC USING BETHESDA SYSTEM

Abstract

Background: Fine needle aspiration cytology [FNAC] is a valuable screening tool available for distinguishing between benign and malignant thyroid swelling. Thyroid lesions subjected to FNAC are categorized under Bethesda system to ensure standardization amongst reporting.
Methods and Material: This prospective study was done over a period of 2 years, i.e., April 2021 to March 2023 in the Department of Pathology, Sri Venkateswara Medical College, Tirupati. A total of 600 patients with thyroid lesions attending the OPD’s of Surgery, Medicine and ENT were included in this study.
Results: Benign lesions were the most commonly found lesions. In present study, females are most commonly involved. Among follow-up malignancy prevalence was increased amongst those with Category V and Category 6.
Conclusions: FNAC is a cost-effective system for screening malignant lesions. The Bethesda System for Reporting Thyroid Cytopathology (TBSRTC) helps in the interpretations of cytological findings of thyroid using FNAC.
