Detectability of Hygroscopic Clips Used in Breast Cancer Surgery.

Sonographically detectable clips were introduced over the last decade. We retrospectively studied the rate and duration of sonographically detectable clip detectability in patients with breast cancer who had sonographically detectable clips inserted over a 2-year period. Nine of 26 patients had neoadjuvant chemotherapy, with all clips remaining detectable 140 to 187 days after insertion.

Resection margins in ultrasound-guided breast-conserving surgery.

Background: Few published studies have shown the benefits of intraoperative ultrasound in avoiding inadequate margins in breast-conserving surgery. The aim of this study is to quantify intraoperative ultrasound margin size and assess its relationship to tumor size, multifocality, palpability, histology, and presence of intraductal component.

Methods: Patients with breast cancer undergoing breast-conserving surgery in whom the operating surgeon visualized the tumor by ultrasound were included.

Increased mammographic screening and use of percutaneous image-guided core biopsy in non-palpable breast cancer: impact on surgical treatment.

Background: Major efforts are being directed at the early diagnosis of breast cancer. The diagnosis rate of non-palpable tumors is steadily growing as a result of increased screening by mammography. In most patients with non-palpable lesions, percutaneous image-guided biopsies have replaced wire localization with surgical excision for obtaining tissue diagnosis.
