Abstract PO5-27-11: A COMPARATIVE STUDY OF DIAGNOSTICS MADE BY FINE NEEDLE ASPIRATION (FNA) BIOPSY VERSUS TRU-CUT FOR BREAST PATHOLOGY IN A ONE STOP CLINIC PROGRAM IN MEDELLIN, COLOMBIA

Abstract

Abstract Breast cancer is the leading cause of morbidity and mortality among women in Colombia due to non-communicable chronic diseases. This has prompted health insurance companies to develop innovative initiatives to mitigate these negative outcomes. Since September 2018, Ayudas Diagnósticas SURA, in alliance with the Gustave Roussy Hospital and General Electric Healthcare has promoted a “One-stop clinic” program called: “TIEMPO PARA TI”. One of the primary challenges was to demonstrate that breast cytology, based on the Yokohama guidelines approved by The International Academy of Cytology has a high sensitivity, specificity, and diagnostic accuracy. The Yokohama system for classifying breast cytology is comprised of five categories: C1 not satisfactory, C2 benign, C3 atypical, C4 malignancy suspected, and C5 malignant. From September 2018 to December 2022, consecutive patients referred for breast biopsy and suspected of having breast cancer underwent triple assessment of breast tumor and were included in this retrospective study. Descriptive analysis was made using STATA v17 software to compare fine needle aspiration (FNA) biopsy versus Tru-cut. A total of 14,501 patients were included, 14.398 FNA and 14.401 trucut biopsies were performed. The comparative analysis showed a 99% concordance between categories 2, which correspond to benign lesions and 96.7% between categories 5, which correspond to malignant lesions. Our findings demonstrate that a well-executed FNA biopsy is not inferior to a trucut biopsy, as revealed by the Yokohama system, and offers significant advantages, such as cost-effectiveness and prompt diagnosis. Both techniques should be used with caution, considering their advantages and disadvantages.
