Intraoperative ultrasound: improved resection rates in breast-conserving surgery.

چکیده
AIM The objective of this study was the investigation of a possible improvement of tumor resection rate, i.e. R0 vs. R1 resection when intraoperative ultrasound evaluation of tissue margins is used during breast-conserving surgery (BCS). PATIENTS AND METHODS A total of 250 cases were evaluated retrospectively. The impact of ultrasound analysis onto clean margin rates was evaluated. A subgroup analysis assessed histology, stage, and neoadjuvant therapy with respect to R0 resection rate and ultrasound evaluation. RESULTS Of 250 BCS cases 84, (33.6%) underwent intraoperative ultrasound and 166 (66.4%) did not. Clean primary surgical margins (R0) were demonstrated for 218 (87.2%) patients after histological analysis. R0 resection was achieved in 81 (96.4%) patients in the ultrasound group compared to 137 (82.5%) in the control group. The difference between the two groups is significant. CONCLUSION This study revealed a significant increase in R0 resection rates when intraoperative ultrasound was used to evaluate surgical margins.

Optimization of breast cancer excision by intraoperative ultrasound and marking needle - technique description and feasibility
BACKGROUND We present a surgical technique and the preliminary results of breast cancer excision after insertion of a specially constructed marking needle into the tumor, controlled by intraoperative ultrasound. Resection margins were projected in six directions by ultrasound measurements, determined in relation to the needle, and resection was done in accordance with those measurements. The ma...

BACKGROUND The purpose of this study was to evaluate ultrasound-guided surgery for palpable breast cancer by comparing the standard palpation-guided surgery in terms of the extent of healthy breast tissue resection, the percentage of tumor-free margins, and cosmetic outcomes. METHODS This was a prospective, observational cohort study conducted from January 2009 to July 2011. Breast cancer pat...

متن کاملNovel techniques for intraoperative assessment of margin involvement
Breast conserving surgery (BCS) is now the standard of care for the majority of women with early stage breast cancer. There is a finite rate of ipsilateral breast tumour recurrence (IBTR) for breast conserving therapy (BCT) with annual rates of less than 1% for specialist breast practices. There has been recent consensus on the definition of an adequate resection margin for both invasive and no...
