About this study

This phase I trial studies the performance, including ultrasound visibility, of an optimized ultrasound twinkling marker in imaging lymph nodes in patients with clinically node-positive breast cancer. In patients with biopsy-proven breast cancer, biopsy markers are used to identify the sites of cancer involvement in both the breasts and lymph nodes. These biopsy markers are critical for guiding surgical management many months after the marker is placed. For breast radiologists and breast surgeons, there is a need for simple, consistent visibility of biopsy markers by ultrasound, particularly several months after marker placement. Ultrasound is the imaging method of choice, particularly for lymph nodes in the armpit (axilla). Ultrasound is non-ionizing and is more comfortable for patients compared to mammography. However, ultrasound visibility of these markers is challenging and inconsistent, with ultrasound failing to detect the marker approximately 25% of the time. The Mayo-designed investigational biopsy marker takes advantage of an ultrasound phenomenon called twinkling artifact. The Mayo-designed optimized ultrasound twinkling marker may work better than standard biopsy clip marker in imaging lymph nodes in patients with clinically node-positive breast cancer.
