Tuesday, November 30 | 3:40 p.m.-3:50 p.m. | SSJ02-05 | Room E450AUsing ultrasound to take a second look at women with breast cancer who have already undergone mammography and an initial ultrasound can help find additional, smaller malignant lesions, but many of these belong to lower-risk BI-RADS categories, according to researchers from Hospital Universitario 12 de Octubre in Madrid.
In this Tuesday afternoon session, Ana Belen Delgado, MD, and colleagues will present findings from a study that included 228 women with known breast cancer; the study was conducted from December 2007 to January 2010.
From among 228 consecutive breast MRI reports (the analysis included cases of preoperative evaluation of patients with known cancer), 138 lesions were nonpalpable, visible on MRI, and occult on first-look ultrasound. Ultrasound and mammography were recommended for a second look, and Delgado's team ended up studying 123 lesions.
The team made ultrasound correlation in 76 (64.4%) of the lesions, with 26 (34.2%) of these being malignant cases.
Most additional malignant lesions of multifocal, multicentric, and bilateral nonpalpable carcinomas detected at second-look ultrasound that were previously unsuspected by mammography and ultrasound at diagnosis are small (less than 7 mm) and BI-RADS categories 2 and 3, the team concluded.
