The purpose of this study was to investigate indications of breast ultrasonography referral. We investigated the positive predictive values (PPVs) of the BI-RADS categorization and histopathologic results in a young women less than 30 years old.
Methods and Materials
We included 811 women under 30 years old who underwent a breast ultrasound (US) during the study period. The mean age of all subjects was 24.5 years (range, 11-29 years). We evaluated the reasons for US referrals based on the presence or absence of symptoms in each patient. Histopathologic results were compared with the results after application of the BI-RADS categorization.
Of the total subjects, 588 women (72.5%) were symptomatic when they underwent breast US. A palpable mass was the most common reason for referral (n=451). The most common reason for referral for asymptomatic women was routine screening (n=111). US findings were classified as category 1 (n=192), category 2 (n=81), category 3 (n=399), category 4 (n=134), and category 5 (n=5). The PPVs for category 1, 2, 3, 4, and 5 were 0, 0, 0.3, 6.3, and 100% in the symptomatic group, respectively. For the asymptomatic group,...
The primary indication for breast US referral was evaluation of a palpable mass. BI-RADS categorization was helpful for predicting of the probability of malignancy. A follow-up US should be performed for high risk women even if they are young and asymptomatic.
