Breast Cancer Clinical Trial

A Pilot Study of Tomographic Optical Breast Imaging (DBT-TOBI) to Monitor Response to Neoadjuvant Therapy

Summary

This research study is evaluating whether the use of digital breast tomosynthesis and near-infrared tomographic optical breast imaging (DBT-TOBI) scans can predict the response of triple negative or HER2+ breast cancer to neoadjuvant chemotherapy.

The study radiologic scan involved in this study is digital breast tomosynthesis (also called 3 Dimensional mammogram) combined with near-infrared tomographic optical breast imaging, or DBT-TOBI.

Full Description

This research study is a Pilot Study, which is the first time investigators are examining this study device for this indication.

The FDA (the U.S. Food and Drug Administration) has not approved DBT-TOBI as a diagnostic scan for this disease.

The DBT-TOBI scan system is designed to deliver low power laser lights through a person's body tissue and collect data about the light that is transmitted through. In this study, the DBT-TOBI will be used to scan the breast. The data that can be collected through the scan is the total hemoglobin concentration and hemoglobin oxygen saturation. Hemoglobin is the protein found in red blood cells that is responsible for carrying oxygen to the various tissues in the body. These two data types are thought to provide insight into the response of the breast cancer to neoadjuvant chemotherapy treatment response. The researchers are looking to find if these scans will help show changes in the hemoglobin levels, thus showing how the cancer is reacting to treatment. The study is focused on 2 types of breast cancer called triple negative breast cancer and Human Epidermal Growth Factor Receptor 2 (HER2).

Eligibility Criteria

Inclusion Criteria:

Female
Participant will be receiving neoadjuvant chemotherapy at the Massachusetts General Hospital (MGH) Center for Breast Cancer.
Participants must have measurable disease, defined as at least one lesion that can be accurately measured as ≥10 mm in the longest diameter with breast MRI, mammography or ultrasound. See Section 11 for the evaluation of measurable disease.
Patients must have Humane Epidermal Growth Factor Receptor (HER2) positive (regardless of Hormone Receptor (HR) status) or Triple Negative (TN) disease as confirmed by pathology. HER2 positive is defined according to ASCO-CAP guidelines, and patient will be receiving HER2 directed therapy. TN is defined as Estrogen Receptor <=1%, Progesterone Receptor <= 1%, and HER2 negative by American Society of Clinical Oncology (ASCO) - College of American Pathologists (CAP) guidelines. For tumors with discordant or borderline receptor findings, the Principal Investigator will adjudicate the final decision.
Age 18 and above.
Ability to understand and the willingness to sign a written informed consent document

Exclusion Criteria:

Patients with open wounds on the breast.
Patients who have undergone breast surgery or breast biopsy 10 days or less prior to the first planned optical imaging scan.
Patients with breast implants.
Patients whose primary lesion is outside the field of view of the optical imaging system.
A history of ipsilateral disease (including invasive breast cancer, ductal carcinoma in situ (DCIS), and benign lesions) or breast surgery.
Patients who are pregnant or trying to become pregnant.
Medical or psychiatric conditions which, in the opinion of the investigator, might result in risk to the subject from participation in the study or inability to complete the study.

For patients who agree to participate in the optional MRI study, these following additional exclusion criteria also apply:

Neurostimulators;
Pacemakers;
Implanted metallic material or devices (metal implants or large tattoos in the field of view);
Severe claustrophobia;
Physical characteristics (weight and/or size) that exceed the capabilities of the MRI scanner;
Known allergy or hypersensitivity reactions to gadolinium, versetamide, or any of the inert ingredients in gadolinium-based contrast agents;
Severe renal insufficiency, e.g., estimated glomerular filtration rate < 30 mL/min.
