简要总结
This phase I study assesses the safety, ultrasound visibility (conspicuity), and movement from normal position (migration) of the twinkling marker in patients with breast cancer that has spread to the axillary lymph nodes (locally advanced) who will be undergoing neoadjuvant systemic therapy and surgery. Biopsy markers are used to identify the sites of cancer involvement in both the breasts and lymph nodes. These biopsy markers are needed to help guide breast cancer surgery. Twinkling markers are designed to have the same size and shape of conventional biopsy markers, but are made of a radio-opaque material that assists with localization of the marker. The twinkling marker may make it more easily seen with ultrasound at the time of breast cancer surgery as compared to conventional biopsy markers.
详细描述
PRIMARY OBJECTIVE:
I. To show that the biologically inert, Food and Drug Administration (FDA)-approved material that comprises the Mayo-developed twinkling marker, either pre-made and sterilized or made immediately before placement, (Patent Application Title: Non-Metallic Ultrasound-Detectable Markers Patent Application No.: 62/903,078, Application Type: Provisional) remains conspicuous under ultrasound after neoadjuvant systemic therapy in patients with clinically node-positive breast cancer.
SECONDARY OBJECTIVE:
I. To evaluate the safety and migration of the Mayo-designed twinkling marker in patients during neoadjuvant systemic therapy (NST).

入选标准
- •Patient 18 years or older with breast cancer and biopsy-proven malignant involvement of an axillary lymph node
- •Surgical management will be determined by the surgeon, who will decide if preoperative I-125 seed localization of the positive node is necessary or if they will retrieve the positive node with intraoperative ultrasound guidance. During surgery, the targeted node, its associated biopsy markers, I-125 seed if placed, and twinkling marker will be resected. The position of the marker in the lymph node or proximity to the node will be noted from the surgical and pathology documentation.
- •Surgery will be performed by one of the surgeons in the Division of Breast and Melanoma Surgical Oncology (Dr. Judy Boughey, Dr. Amy Degnim, Dr. Tina Hieken, Dr. Jeffrey Johnson, Dr. Mary Mrdutt, Dr. Dalliah Black, Dr. Mara Piltin)
- •Patients must be able to understand the study procedures and comply with them for the entire length of the study
- •No contraception is necessary or required
排除标准
- •Current drug or alcohol use or dependence that, in the opinion of the site investigator, would interfere with adherence to study requirements
- •Inability or unwillingness of individual or legal guardian/representative to give written informed consent
- •Current or past participation within a specified timeframe in another clinical trial, as warranted by the administration of this intervention
结局指标
主要结局
Long-term efficacy of the twinkling marker
时间窗: through study completion, an average of 4 months
The primary outcome is information on the long-term efficacy of the twinkling marker in humans placed in the lymph nodes of patients undergoing neoadjuvant systemic therapy (NST) for breast cancer. The data will explore the presence/absence of the twinkling artifact associated with the twinkling marker under ultrasound.
次要结局
- Determination of safety and migration of the twinkling marker(through study completion, an average of 4 months)
