Feasibility of Ultrasound Microbubble Contrast-Enhanced (CEUS) Ultrasound Sentinel Lymph Node Imaging With Guided Biopsy in Breast Cancer Patients

The goal of this clinical research is to learn if an ultrasound contrast agent called OPTISON (perflutren protein type A) is effective in finding sentinel lymph nodes before surgery. Contrast agents can help make ultrasound images more accurate. The sentinel lymph node is the first node that may be the target of cancer cells that spread from the tumor.

Study Procedures: If you agree and are eligible to take part, you will receive perflutren protein type A by injection under the skin near the nipple. After you receive the injection, the radiologist will take more ultrasound images and videos of the tumor and lymph nodes in the underarm area. You will have a biopsy of the sentinel lymph node that was identified in the ultrasound and a titanium clip marker will be inserted into the node. The clip helps distinguish the biopsied node from other nodes. You will be told the results of biopsy. After the biopsy, a radioactive seed may be inserted into the node to allow the surgeon to find and remove it during your surgery, an extra node may be removed at that time. You will still have standard of care sentinel lymph node biopsy during your already scheduled surgery. You will sign a separate surgical consent form that explains this procedure and its risks. You will be called by phone 30 days after the seed is removed to check for any side effects. This phone call should take about 10 minutes. Length of Study: Your active participation in this study will be over the follow up phone call. This is an investigational study. Perflutren protein type A is FDA approved and commercially available for use in contrast-enhanced echocardiograms. Its use in this study is investigational. Up to 21 patients will take part in this study. All will be enrolled at MD Anderson.

Participants receive a subdermal periareolar injection of 0.2 - 0.5 cc of microbubble contrast Perflutren Protein-Type A Microspheres Injectable Suspension (OPTISON™). Ultrasound images and videos of tumor and lymph nodes in underarm area taken. Biopsy of sentinel lymph node that was identified in ultrasound performed, and a titanium clip marker inserted into the node. After biopsy, a radioactive seed may be inserted into the node to allow surgeon to find and remove it during surgery. Participant called by phone 30 days after seed is removed to check for any side effects. This phone call should take about 10 minutes.

Number of Breast Cancer Participants With Sentinel Lymph Nodes (SLN) Identification Using the CEUS Technique

Following the Microbubble CEUS of ipsilateral axillary nodes, needle biopsy and I-125 seed placement, a single node/participant (biopsied node) will be included in the statistical evaluation. The technique determined as technically feasible if an enhancing node is visualized in at least 90% of the subjects and 80% concordance is achieved between imaging-guided biopsy and final surgical histopathology. If no enhancement is identified, the overlying skin will be massaged, and re-injection of contrast will be employed up to three times. If no contrast enhancement in lymphatics is observed, the case will be reported as a failure of the CEUS technique.

Inclusion Criteria: 18 years or older. Ipsilateral biopsy-proven invasive breast cancer <5 cm in maximal dimension by Ultrasound or Mammography. No abnormal axillary nodes identified on grayscale AUS, or abnormal nodes with benign subsequent FNA biopsy. Exclusion Criteria: Pregnant or nursing women Prior SLN dissection Neoadjuvant chemotherapy. Prior axillary lymph node surgery. Prior history of ipsilateral breast cancer. Known or suspected: Cardiac shunts Known or suspected: hypersensitivity to perflutren, blood, blood products or albumin Known or suspected: hypersensitivity to a prior OPTISON administration
