Countries: United States
This study will investigate Harmonic Motion Imaging guided Focused Ultrasound (HMIgFUS) method for ablation and sonoporation monitoring of breast tumors. The aim of this study is to evaluate the efficacy of real-time guidance/monitoring and ablation/sonoporation method. The hypothesis behind this proposed study is that High Intensity Focused Ultrasound (HIFU) can be used to ablate tumor tissue, and microbubble-mediated Low Intensity Focused Ultrasound (LIFU) can be used to sonoporate tumor vasculature. The investigators of this study also hypothesize that HMI can be used to monitor HIFU ablation by measuring the changes in tissue stiffness that occur as a result of thermal ablation, guide LIFU sonoporation and HIFU ablation targeting stiff tumor tissue, and the HMI-monitored stiffness changes during ablation will correlate with post-treatment immune response. The ultimate goals of this study are: first, to assess whether these techniques can be used in the clinic in order to provide a well-monitored, noninvasive tumor ablation/sonoporation method for benign tumors and breast cancers, to minimize side effects due to invasiveness and enhance therapeutic effects of current methods; second, to make full use of the real-time monitoring capability of HMIgFUS for more precise, point-of-care treatment planning to ensure success of ablation/sonoporation and immune activation.

Focused Ultrasound Surgery Inclusion criteria: * Women age 18 years or older with benign tumors or early-stage, non-metastatic breast cancer (stage I without the involvement of axillary lymph nodes) * Scheduled to receive surgical resection of the tumor by their clinical care team Exclusion criteria: * Patients who have received or are scheduled to receive thermal ablation or treatment of the tumor as part of their clinical care * Pregnant or lactating * Presence of breast implants * Have a history of laser or radiation therapy to the targeted breast. Microbubble-mediated LIFU, i.e., sonoporation Inclusion criteria: * Women 18 years or older * Deemed eligible to receive neoadjuvant systemic therapy as per the treating physician, with the dose and schedule deemed appropriate by the treating physician * Any stage invasive breast cancer provided the primary breast tumor size is at least 4 mm Exclusion criteria: * Pregnant or lactating * Presence of breast implants * History of laser or radiation therapy to the affected breast * Contraindication history or hypersensitivity to ultrasound contrast agents, e.g., Definity, including polyethylene glycol (PEG) allergy.
