Role of International Academy of Cytology Yokohama reporting system in breast lesions at a tertiary care center in Central India

Abstract

Abstract Background: The International Academy of Cytology (IAC) Yokohama System to report breast cytopathology can effectively categorize breast diseases into different cytological groups. Fine needle aspiration (FNAC) from the lesions in the breast has been regarded as an effective method of diagnosing breast cancer, particularly in rural settings. The principal purpose of this study was to validate the diagnostic accuracy of breast FNA utilizing the IAC Yokohama system in future endurances. Histopathological evaluation was also performed to corroborate the correctness of the FNA of the breast.Methods: Research on patients getting core-needle/incisional/excisional biopsy of breast lesions between January 1st, 2021, and December 31st, 2021, was conducted at a tertiary care center in central India. 216 breast FNAs were recorded utilizing the IAC Yokohama system, and the most appropriate category was assigned for every case.Results: The new “International Academy of Cytology (IAC) Yokohama system” was used to categorize 216 patients into five categories based on the cytologic diagnosis. That C1: insufficient material (8.7%), C2: benign (65.7%), C3: atypical (1.8%), C4: suspicious of malignancy (2.7%), and C5: malignant (20.8%). To examine diagnostic accuracy, FNACs were associated with ancillary testing and histological diagnosis. The overall specificity, sensitivity, negative predictive value, and positive predictive value, along with the accuracy, were calculated with the risk of malignancyConclusion: With high specificity and sensitivity, for each type of situation, for all tumors, and each analyzed BIRADS category show that the IAC Yokohama system provides excellent accuracy for Breast FNA.
