Diagnostic US for Reduction of Benign Breast Biopsies Using US-guided Optical Tomography

United States298 participantsStarted 2019-03-05

Plain-language summary

Ultrasound-guided diffuse optical tomography (DOT) has demonstrated its potential role in differentiating malignant and benign breast abnormalities and in predicting and monitoring the neoadjuvant chemotherapy (NAC) response of breast cancer. This unique approach employs a commercial ultrasound (US) transducer and near infrared (NIR) optical imaging sensors mounted on a hand-held US probe. The co-registered US is used for lesion localization, and optical sensors are used for imaging tumor related vascularity.

Inclusion Criteria: * Female subjects ≥ 18 years old with ultrasound visible breast abnormalities (BI-RADS 3\*, 4A, 4B, 4C, and 5) referred for ultrasound-guided core needle biopsy or fine needle aspiration \*note that while a BI-RADS 3 assessment is probably benign, a subset of patients with this assessment choose to undergo biopsy rather than follow up imaging). * Willing and able to provide informed consent Exclusion Criteria: * Lesions located in the darkly pigmented nipple-areolar complex area * Subjects with breast implants * Abnormality in the mirror image location of the contralateral breast. * Additional abnormalities in the same region of the breast that would be included in US-guided DOT imaging of the abnormality undergoing biopsy * Previous breast irradiation of the mirror image location of the contralateral breast * Lesions located at previous biopsy sites when biopsy occurred within the last six months. * Pregnancy * Superficial abnormalities located entirely within (i.e. less than) 5mm of the overlying skin

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.

What they're measuring

Impact of US-guided DOT on the Potential Reduction of Benign Biopsies as Measured by Comparing the Reads With a Non- Suspicious Assessment of Conventional Imaging (CI) Alone Versus CI & US-DOT

Timeframe: Completion of enrollment for all patients (61 months), the imaging session took approximately 1 hour for the participating patient

Impact of US-guided DOT as an Adjunct to Conventional Breast Imaging on Maintaining High Sensitivity as Measured by Comparing the False Negative Rate or Missing Malignancy of Conventional Imaging (CI=US +/- Mammography) Alone Versus CI & US-DOT

Timeframe: Completion of enrollment for all patients (61 months), the imaging session took approximately 1 hour for the participating patient

Assess the Impact of Adjunctive US-guided DOT Data in the Management of Discordant Pathology Results

Timeframe: Completion of enrollment for all patients (61 months), the imaging session took approximately 1 hour for the participating patient
