Videssa Breast can effectively detect BC when used in conjunction with imaging and can substantially reduce unnecessary medical procedures, as well as provide assurance to women that they likely do not have BC.
Advances in stereotactic breast biopsies have introduced a variety of devices that yield different sizes of tissue samples. The choice of biopsy device should be based on which technique is most likely to yield a definitive diagnosis at the time of the initial biopsy. This is a prospective study of 104 patients who underwent a total of 125 stereotactic breast biopsies using the SiteSelect large-core biopsy device. From May 1999 to June 2001, 104 patients underwent 125 stereotactic breast biopsies with the SiteSelect large-core biopsy device. One hundred four 15 mm SiteSelect biopsies, eighteen 10 mm SiteSelect biopsies, and three 22 mm SiteSelect biopsies were performed. Atypical ductal hyperplasia (ADH) and ductal carcinoma in situ (DCIS) were found in 15% of the biopsies and infiltrating cancer was found in another 15% of the biopsies. Seventy-eight percent of the ADH and 90% of the DCIS lesions were associated with indeterminate calcifications noted on mammogram. Two of the 22 mm SiteSelect excisions yielded a specimen that contained the entire cancer with clear surgical margins. All of the patients with DCIS or invasive carcinoma underwent definitive surgical and adjuvant therapy. The sensitivity and specificity of SiteSelect in this series of patients was 100%. The SiteSelect biopsy procedure is safe, well tolerated by patients, and can be performed under local anesthesia. SiteSelect is comparable to an open excisional biopsy in its ability to obtain adequate tissue for accurate diagnosis, but excises significantly less normal surrounding breast tissue. Based on the data, indications for primary use of SiteSelect are indeterminate calcifications on mammogram, rebiopsy of a vacuum-assisted biopsy site that yielded atypia on pathologic examination, and complete excision of a lesion suspicious for invasive carcinoma in order to assess actual size and margin status.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
