title: Vacuum-assisted breast biopsies. Experience at the Antoine Lacassagne Cancer Center (Nice, France).
abstract: This article presents the results of the first 318 aspiration-guided breast macrobiopsies performed using a dedicated table at the Antoine Lacassagne Cancer Center (Nice, France) between January 2001 and November 2002. A total of 288 procedures (90%) was performed for microcalcifications whereas that of 30 (10%) was performed for isolated opacities. There were 170 American College of Radiology (ACR) Category 4 (53.45%), 35 ACR 5 (11%), 111 ACR 3 (34.9%), and 2 ACR 2 lesions. There were 233 benign lesions that included 19 cases of atypical epithelial hyperplasia. Of the 85 malignant lesions, 33 had an invasive component. Seven of the atypical epithelial hyperplasia cases and all of the malignant lesions were managed surgically. Atypical epithelial hyperplasia was underestimated in 28.57% of the cases; ductal carcinomas in situ, in 21.15%. The positive predictive value of ACR 4 for the diagnosis of malignancy was 24.7% (42/128 cases), versus that of 12.6% for ACR 3 (14/97 cases). Among the 233 benign lesions, 128 were classified as ACR 4 and 6 as ACR 5 (all of these procedures obviated surgery). The advantages, drawbacks, and limitations of the technique are analyzed and indications are discussed, particularly for ACR 3 lesions.
