Description
Objective To assess the performance of breast ultrasound based on BI-RADS final assessment categories in women with mammographically negative dense breast. Methods Of 3,820 cases with mammographically negative dense breast and subsequent hand-held bilateral wholebreast ultrasound, a total of 1,507 cases in 1,046 women who had biopsy or at least 2-year follow-up ultrasound constituted the basis of this retrospective study. Cancer rate of each sonographic BI-RADS category was determined and medical audit was performed separately in screeninggeneral, screening-treated, and diagnostic group. Results A total of 43 cases (2.9%) were confirmed as malignancy. Cancer rate among BI-RADS categories was significantly different (p<0.0001). Among three groups, the cancer rate was significantly different (p<0.0001) and the highest in diagnostic group (15.8%, 22 of 139). Abnormal interpretation rate, PPV of biopsy performed, cancer detection rate, and rate of early stage cancer, and the size of invasive cancer were significantly different among three groups and the highest in diagnostic group. Regarding cancer characteristics, the proportion of advanced cancer was the highest in diagnostic group. Conclusion Breast ultrasound based on BI-RADS as an adjunctive to negative mammography can be useful for predicting malignancy in women with dense breast.
