Abstract

We report our experience with stereotactic core breast biopsies (SCBB) for mammographically suspicious, nonpalpable breast lesions. Ninety-seven patients, ages 29 to 94 (mean 57.3 years) underwent SCBB with a 14-gauge Biopty gun. A mean of 5.0 cores was taken from each lesion. Lesions were mammographically categorized by suspicion (high, > 60% chance of malignancy; intermediate, 25-60%; low, < 25%) and according to lesion character (well-defined mass, indistinct mass, spiculated mass, asymmetric density, and clustered microcalcifications [CM]). Histologic and radiographic findings were correlated at the time of biopsy and again retrospectively, with 92 percent correlation and eight percent partial or non-correlation. Of the latter, five of eight lesions represented CM not seen in the histologic samples. Of the 97 sampled lesions, 72 (74%) had been radiographically categorized as low suspicion, 10 (10%) as intermediate, and 15 (16%) as high. The procedure saved 74 women (76%) from open biopsy and added a diagnostic procedure for eight women (8%). Fifteen women (15%) went directly to mastectomy; therefore, the SCBB neither added nor saved a procedure for patients with cancer. Of the 72 lesions categorized as low suspicion, 65 (90...Continue Reading
