dc.description.abstractPurpose: Breast fine needle aspiration cytology (FNAC) has a long history of providing accurate, rapid and cost-effective diagnosis of palpable breast lesions. Recently, International Academy of Cytology (IAC) at Yokohama proposed a new reporting system for breast cytology, in order to bring uniformity across the globe. Any new classification system needs to be validated for its practical applicability. Objectives: This study was conducted to categorize the breast lesions as per this classification and further determine the diagnostic efficacy and risk of malignancy in each category. Material and methods: This was a cross sectional observational analytical study. All the cases presenting to cytology OPD from Janurary 2020 upto December 2022, (N=296) with breast lesions for FNAC were included in the study. All the cases were divided into five categories as per the newly proposed IAC Yokohama reporting system. The risk of malignancy for each category was determined and diagnostic efficacy was evaluated.Results:The sample were distributed as follows: insufficient material 4.39%, benign 66.21%, atypical 10.47%, suspicious for malignancy 1.35% and malignancy 17.56%. Histopathology was obtained in 88 cases, out of which 82 (93.18%) showed concordant diagnosis. The sensitivity and specificity were 85.71% and 98.11% respectively. Risk of malignancy (ROM) in each category was as follows-benign (0.01%), atypia (71.4%), suspicious (100%) and malignancy (96.66%) respectively.Conclusion:The high efficacy of FNAC obtained in the present study, when IAC Yokohama reporting system was applied, confirms the usefulness of this scheme in reporting breast lesions. A risk-based stratification is essential in the present era to guide and alert the clinician about the subsequent management plan and the ROM.en_US
