EVALUATION OF APPLICABILITY OF YOKOHAMA SYSTEM FOR REPORTING OF BREAST FINE NEEDLE ASPIRATION CYTOLOGY: A RETROSPECTIVE STUDY IN A TERTIARY CARE CENTER

Background:Breast cancer is most common cancers in reproductive women and also the leading cause of deaths worldwide. First line invasive investigation breast lump Fine needle aspiration cytology (FNC) to categorized lesion as benign or malignant. Recently, an expert panel published [International Academy Cytology](IAC) Yokohama System for reporting classification cytopathology. The aim present study was evaluate applicability system reporting. Materials Methods: In this retrospective studya total 612 FNC specimens from 1st January 2021 31st October were obtained. These reclassified according Risk malignancy (ROM), sensitivity, specificity, Positive Predictive Value (PPV), Negative (NPV) diagnostic accuracy calculated. Result: Out cases histo-pathological correlation available 355 cases. ROM calculated each category system. 10% 1, 2.5% 2, 44.4% 3, 100% 4 5. Sensitivity, positive predictive value, negative value FNAC respectively 94.3%, 96.2%, 89.1%, 98.4% 99.1% , respectively. Conclusion: conclusion, IAC Breast cytopathology simple but it simultaneously enables greater accuracy, consequently better patient care.
