ABVS can provide additional information in the differential diagnosis of a lesion. It has significantly higher sensitivity than mammography, but it is similar to manual US and cannot be preferred to a manual US examination.
Shear-wave elastography gives quantitative elasticity information that could potentially help in breast-lesion characterisation, although it cannot replace conventional BI-RADS in the differentiation of breast lesions.
The aim of this study was to evaluate a 10-gauge vacuum-assisted system for the excision of clinically benign breast lesions. The minimal excision of 245 lesions in 162 patients was performed with VACORA vacuum-assisted system under the guidance of ultrasound between July 2007 and April 2008. The lesions were category 3 lesions as determined by ultrasound imaging according to Breast Imaging Reporting and Data System (BI-RADS) (n=208) or had been confirmed as benign by a previous core-needle biopsy (n=37). As many as 244 lesions were demonstrated to be benign and one case was demonstrated to be malignant by pathology after resection. In the 244 benign lesions, 220 lesions were excised completely as demonstrated by the follow-up ultrasound examination. The malignant lesion was managed with surgical excision. The 10-gauge vacuum-assisted system is highly successful for the excision of benign breast lesions; it is an alternative tool for minimal treatment of benign breast lesions.
The aim of this study was to evaluate if re-biopsy with 10-gauge vacuum-assisted biopsy (VAB) could get definitive diagnosis for breast lesions with ultrasound (US) imaging-histologic discordance at 16-gauge core needle biopsy (CNB). From January 2007 to June 2008, a consecutive biopsy was performed on 1069 lesions with US-guided 16-gauge CNB. A total of 28 lesions were considered to be US imaging-histologic discordant and all of them underwent subsequent 10-gauge VAB. All malignant lesions located at VAB were treated with subsequent surgery and all benign lesions at VAB were followed up for at least 1 year. Six of the 28 lesions (21.4%) had pathologic upgrade after VAB. In them, one case upgraded from adenosis to ductal carcinoma in situ (DCIS); one case upgraded from adenosis to infiltrating ductal carcinoma (IDC); one case upgraded from atypical ductal hyperplasia to IDC; two cases upgraded from intraductal papilloma to DCIS; and one case upgraded from sclerosing adenosis to invasive lobular carcinoma (ILC). The subsequent surgery further demonstrated the diagnosis of VAB for all the lesions with histologic upgrade. Re-biopsy could improve diagnostic accuracy in patients with breast lesions showing imaging-histologic discordance during CNB, and 10-gauge VAB was a valuable method to deal with re-biopsy.
The aim of this study was to determine the role of vacuum-assisted biopsy (VAB) in patients with ultrasound imaging-histologic discordance during 16-gauge core needle biopsy (CNB) and to compare VAB with vacuum-assisted removal (VAR) in diagnostic accuracy in patients with ultrasound imaging-histologic discordance. From January 2006 to October 2008, a consecutive biopsy was performed on 1532 lesions with ultrasound-guided 16-gauge CNB. Sixty two lesions were considered to be ultrasound imaging-histologic discordant. Among the 62 lesions, 55 lesions underwent subsequent VAB or VAR, which made up our study population. Among the 55 cases, 22 underwent subsequent US-guided VAR, and the other 33 lesions underwent subsequent US-guided VAB. All malignant lesions at VAB and VAR got subsequent surgery, and all benign lesions at VAR or VAB were followed up for at least 1 year. Five lesions of the VAR group were diagnosed as having carcinoma (5/22, 22.7% of pathologic changing rate). Seven lesions of the VAB group were diagnosed as having carcinoma (7/33, 21.2% of pathologic changing rate). Subsequent surgery further demonstrated the diagnosis of VAB for all the lesions with pathologic change. There was no significant difference in pathologic changing rate between these two groups (p < 0.05). A US-guided VAB was a valuable alternative to VAR or surgery excision to obtain definitive diagnosis in patients with breast lesions showing imaging-histologic discordance during 16-gauge CNB.
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.
