Maximizing diagnostic precision: Evaluating the combined Yokohama and BI-RADS scoring system for breast lesions

The diagnosis of breast cancer necessitates a multifaceted approach integrating cytopathological and radiological assessments. The International Academy of Cytology (IAC) Yokohama system and Breast Imaging Reporting and Data System (BI-RADS) are fundamental frameworks in this context. This study aims to evaluate the diagnostic potential of a combined Yokohama-BI-RADS scoring system for breast lesions.

A retrospective analysis was conducted on fine needle aspirates from January to June 2023. The cases were classified using the IAC Yokohama system and sono-mammography BI-RADS score. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and diagnostic accuracy were calculated using histopathological diagnoses as the reference standard. Optimal cut-off scores for the combined scoring system were determined.

Among 52 patients, cytological diagnoses encompassed non-diagnostic, benign, atypical, suspicious of malignancy, and malignant categories. BI-RADS scores ranged from 1 to 5. The combined Yokohama-BI-RADS score exhibited superior diagnostic accuracy (AUC: 0.986) compared to individual systems.

The combined Yokohama-BI-RADS scoring system represents a promising advancement in breast lesion evaluation, providing enhanced diagnostic precision by integrating cytopathological and radiological data. This approach has the potential to optimize clinical decision-making and contribute to improved patient outcomes in breast cancer management.
