MENAGERIE OF BREAST LESIONS ON TRUCUT BIOPSIES AND THEIR CORRELATION WITH BIRADS SCORE-3 YEARS INSTITUTIONAL STUDY

Abstract

Breast ultrasound is a primary diagnostic modality for evaluating suspected breast lesions. Histopathological examination of trucut biopsies helps in accurate typing and grading the tumor. In the present study we compared histopathological ndings of trucut breast biopsies with BIRADS score. It was a retrospective, 3 years study with 183 cases that had under gone ultrasound examination and trucut biopsy for histopathological examination. Among 183 cases, 8 were inconclusive, 93 were benign and 82 were malignant. In 183 cases, 62 cases were classied as BIRADS-II, 24 cases as BIRADS-III, 66 cases as BIRADS IV and 31 cases as BIRADS V. Sensitivity calculated was 98.78%, specicity was 86.02%, positive predictive value was 86.17% and negative predictive value was 98.77%. The disease prevalence was 46.86% and accuracy was 92%. P value was statistically signicant. Therefore, we conclude that BIRADS score is non-invasive and a useful test for evaluating breast lesions preoperatively. However, we cannot rely on BIRADS score in cases of sampling error, nature of the lesion or unusual radiological presentation that may lead to interpretation error and thus histopathology will be considered as gold standard in diagnosis of breast lumps.
