Right oblique (A) and craniocarudal (B) mediolateral normal vision selection mammograms show breasts of density C. Coronal (C), transverse (D), and lateral (E) views reconstructed from automatic breast ultrasound (ABUS) demonstrate a slightly hypoechoic circumscribed lesion of 7 mm at the 11 o’clock position in the right morning. The lesion was classified as BI-RADS 3. The patient has undergone annual mammograms for 4 years after the ABUS examination without a diagnosis of breast cancer.

According to ARRS American Journal of Roentgenology (AJR), return to routine screening of BI-RADS 3 lesions in the US supplemented with supplemental whole breasts (ABUS) substantially reduces the recovery rate, although it is unlikely to result in an adverse outcome.

“This prospective study supports a recommendation for routine annual monitoring of BI-RADS 3 in supplemental ABUS, ”wrote lead author Richard G. Barr of Northeastern Ohio Medical University in Rootstown.

From August 2013 to December 2016, the prospective study by Barr and colleagues (NCT02650778) enrolled patients with BI-RADS 1 or 2 a mammography i density C or D for additional ABUS, which was interpreted as BI-RADS 1, 2, 3, or 0. For ABUS BI-RADS 1, return to was recommended, while ABUS BI-RADS 0 lesions underwent targeted manual ultrasound.

A 2,257 (mean age, 58 years), routine follow-up of BI-RADS 3 lesions detected in supplemental ABUS screening in women with dense breasts and any risk resulted in a recovery rate of 3.8% (85 / 2,257), rate of biopsy of 0.5% (12 / 2,257), and a positive biopsy rate of 58.3% (7/12), without lost cancers (95% CI, 0.0-0.86%).

Given that ABUS can help mitigate acquisition variability by standardizing documentation, recording, and archiving ultrasound images of the entire chest (excluding the armpit), Barr et al. reiterated that ABUS images of similar quality can be obtained from properly trained ultrasonographs and mammograms.

“Avoiding prior follow-up of these likely benign lesions can be associated with substantial cost savings,” the authors state. AJR article added.
