Methods and materials
The radiologic and surgical records of 391 patients who underwent image-guided percutaneous biopsy from January 2008 to September 2014 were reviewed.
33 patients with a biopsy-proven high-risk breast lesion in the absence of ductal carcinoma in situ (DCIS) or invasive breast carcinoma in the samples obtained,
were included in the study.
Patients >40 years-old had mammography and whole-breast ultrasound (US) while only US was performed for patients younger.For the mammographic examination,
two-view standard mammograms (and additional projections when necessary) were obtained using a film-screen unit or a full-field digital unit.
The choice of imaging guidance (US or stereotactic) and biopsy technique (trucut or vacuum-assisted biopsy) was made according to the lesion’s visibility.
Biopsies were performed by three attending radiologists with 5-20 years of experience in breast imaging. US-guided trucut biopsy was performed in 256 patients (65.47%) and stereotactic vacuum-assisted biopsy was performed in 135 patients (34.52%). US-guided biopsy was performed by an an automated biopsy gun with a 14-gauge needle obtaining three to six samples. Stereotactic biopsy was performed mainly for calcifications by 9-gauge vacuum-assisted device and a digital prone table obtaining ten to eighteen samples.
According to our protocol, some of the patients underwent an excisional biopsy while the rest were scheduled for a long-term imaging follow-up of 6 months' intervals.
Follow-up was performed by the modality which detected the lesion.
