Abstract

Breast cancer represents the most common cancer diagnosed in women worldwide, constituting 21% of all cancer cases in women. Mammography and ultrasound are the two non-invasive, affordable, widely available radiological interventions that aid in the diagnosis. The Breast-Imaging and Reporting Data System (BIRADS) has been implemented widely for mammography reporting. Core needle biopsy has replaced fine needle aspiration for diagnosing breast lesions. Present study was planned to assess efficacy of BIRADS over histopathology in evaluation of breast lesions Materials and Methods: 145 patients having breast lesions, who had undergone radiological imaging, either ultrasound or mammography, followed by core needle biopsy were enrolled. Mammography reports & Histopathological reports of biopsies of all patients were retrieved from Hospital Information System. All the patients were classified into one of BIRADS categories 2–5. BIRADS category 2-3 was considered most likely benign and BIRADS categories 4–5 was considered as malignant. Breast lesions on histopathology, were classified into benign or malignant, according to WHO classification of tumours, 5th edition, 2022. Observations and Results: Majority of the patients were above 50years of age with Category IV being the most common BIRADS category. On histopathology, total benign cases were 63 (43 %) & malignant were 82 (57 %). Amongst benign lesions, maximum were fibroadenoma & amongst malignant, it was Invasive breast carcinoma, No special type. 52% malignant cases were diagnosed on both BIRADS &biopsy whereas 34% were diagnosed as Benign on both BIRADS &biopsy. 5% cases were considered Benign on BIRADS but categorized as malignant on biopsy. Similarly,9% cases were considered malignant on BIRADS but categorized as benign on biopsy. Sensitivity of BIRADS was found 91.46 % & specificity was 77.78 %. Conclusion: To conclude, BIRADS classification had an acceptable sensitivity & positive predictive(PPV) values for diagnosing breast lesions. However,core needle biopsy is a reliable method and still remains gold standard for diagnosing breast lesions.
