Clinical Trials

The purpose of this study is to evaluate and optimize the performance of the ultrasound decorrelation imaging technique on 10 clinical patients where ultrasonographic clip detection is needed.

The purpose of this study is to collect user and subject feedback on the design, use and operation of Affirm® Contrast Biopsy.

The purpose of this study is to collect blood samples and fresh tissue from biopsies of metastatic lesions from Mayo Clinic patients with metastatic breast cancer. The biospecimens will be used for analysis of genetic alterations in germline and tumor DNA and for tracking of response to therapy using blood-based liquid biopsy approaches. 

The purpose of this study is to to map out the extent of Skin Angiosarcoma disease using ultrasound. This will be compared to the MRI and or PET/CT and with clinical and photographic determination of disease extent confirmed with clinically requested punch biopsies. The patient will be scanned with a commercially avilable GE Logiq 10 machine and then with the 25-30 MHz linear microvessel transducer  for microvessel imaging. These scans will be obtained pretreatment, after 2 cylces of neoadjuvant chemotherapy and after completion of neoadjuvant chemotherapy and radiation therapy prior to surgery. 

This is a Phase 0 clinical trial to evaluate a twinkling biopsy marker (Patent Application Title: Non-Metallic Ultrasound-Detectable Markers Patent Application No.: 62/903,078, Application Type:  Provisional) for ultrasound conspicuity in patients with breast cancer and locally advanced disease involving the axillary lymph nodes.

The purpose of this study is to determine whether contrast-enhanced ultrasound (CEUS) can be used in diagnostic evaluation of breast lesions that cannot be seen using contrast-enhanced MRI (CEMR) and contrast- enhanced dual energy mammography (CEDM).   If so, patients can undergo US guided biopsy which is more comfortable for patients and more cost effective.

The purpose of this study is to to bring molecular risk prediction for breast cancer into the clinical arena through: the establishment of a large tissue repository from a retrospective cohort of women with benign breast disease with complete and long-term clinical follow-up to identify those who developed breast cancer (cases) and those who did not (controls); the application of potential biomarkers of risk to this archival tissue set; and, the discovery of new, potentially relevant biomarkers of risk in fresh and frozen specimens of benign breast disease. 

The purpose of this study is to apply new microvasculature imaging for differentiation of breast lesions, and prediction of response to preoperative chemotherapy.

This phase II trial studies how well biopsy of breast after chemotherapy works in predicting pathologic response in patients with stage II-IIIA breast cancer undergoing breast conserving surgery. Tumor tissue collected from biopsy before surgery may help to check if chemotherapy destroyed the breast cancer cells and may be compared to the tumor removed during surgery to check if they are the same.

The purpose of this study is to to better understand the concerns of patients prior to a breast biopsy so that we may improve our practice and ultimately enhance overall patient experience.

The goal of this study is to perform a quantitative measure of lobular involution (qLI) from breast biopsy samples obtained at baseline (surgery) and 12 months or at time of study discontinuation. The study will determine breast density (MMG) and correlate with qLI. The study will also determine the influence of chemoprevention therapies such as tamoxifen and letrozole on qLI.

The purpose of this study is to evaluate the timing of AVB-620 administration relative to surgery on the fluorescence and accuracy of the AVB-620 imaging data to distinguish between malignant and nonmalignant tissues in women undergoing surgery with primary, nonrecurrent and nonmetastatic breast cancer.

The purpose of this study is to examine how well axillary reverse mapping works in preventing lymphedema in patients with breast cancer undergoing axillary lymph node dissection. Axillary reverse mapping may help to preserve the lymph node drainage system around the breast so as to prevent lymphedema after surgery.

The overall goal of this project is to study a new 3D ultrasound imaging technology for evaluation of axillary lymph nodes in patients with breast cancer.

The purpose of this study is to look at the effects cancer and melanoma have on the immune cells found in lymph nodes.
