Abstract
OBJECTIVE: Our aim was to determine whether triple-negative breast cancer (TNBC) has distinguishing sonographic features compared to non-TNBC. METHODS: Data from 145 consecutive breast cancer patients were collected. The images were reevaluated by two dedicated breast imaging experts according to the Breast Imaging Reporting and Data System. The sonographic features of 45 TNBC patients were compared with those of 100 non-TNBC patients. RESULTS: TNBC showed a high histological tumor grade. On ultrasound, TNBC was more frequently to present as oval or round mass shape (48.9%, 17.8%; respectively), more likely to have circumscribed margins (82.2%), and less likely to show posterior attenuating (8.9%). Additionally, compared with non-TNBC, TNBC was less likely to have calcification (35.6%). CONCLUSION: TNBC has distinguishing imaging features on breast ultrasound, and more likely to be associated with benign masses. Knowledge of the distinct sonographic features would be useful in diagnosing TNBC.
