PET/MR in Surgical Planning for Breast CA Treated With Neoadj Chemo

Stopped early · Not applicable

Conditions studied: Breast Cancer

In brief

Purpose: To assess the utility of combined, simultaneous positron emission tomography (PET) and magnetic resonance imaging (MRI), collectively called PET-MR, in assessing response to neoadjuvant chemotherapy and surgical treatment decisions for operable breast cancers. Participants: Adult patients with operable breast cancer that are being treated at UNC with neoadjuvant chemotherapy followed by potentially curative surgical resection. Procedures (methods): Patients who are being treated with neoadjuvant chemotherapy followed by surgical resection and for whom pre- and post-treatment MR imaging is part of planned treatment will undergo additional pre-treatment and post-treatment PET/MR. The response to treatment will be assessed at post-treatment by evaluating change in tumor size from MRI, change in response to dynamic contrast enhanced (DCE) MRI, and 18F-fluorodeoxyglucose (18F-FDG) avidity from PET. Patients will then undergo surgery. Their pathology will be reviewed for treatment effect as assessed by residual cancer burden (RCB) score. Patients will be followed and assessed for recurrence.

Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Age ≥ 18 years of age (no upper age limit)
• Signed, IRB-approved written informed consent
• Must have clinical T1-3, N0-3, M0 disease. All phenotypes are acceptable..
• Must have surgically curable disease as evaluated by the UNC Multidisciplinary Tumor Board.
• Must have pre- and post-treatment MRI imaging as part of the treatment plan.
• Must be able to meet size restrictions for the PET-MR scanner: chest depth and abdominal depth less than 27 cm (approximately the smallest 55% of women will meet this), as measured on imaging or with physical template.
• Must be in acceptable health to undergo chemotherapy and curative intent surgery as assessed by Multidisciplinary Tumor Board.
• Must be able to understand and comply with study procedures for the entire length of the study.
• Must receive their chemotherapy and curative intent surgery at UNC Hospitals. -If patient has a history of prior malignancy, including melanoma, patient must be cancer- free for three or more years. Non-melanoma skin cancers will be included even if not cancer-free for three years.
• Women of childbearing potential must have a negative serum or urine pregnancy test performed within 7 days prior to each PET/MRI

You may not qualify if…

• Inability to tolerate MRI (e.g., inability to lie flat for >1 hour)
• Presence of pacemaker, intracranial aneurysm clip, bladder stimulator, cochlear implant or metal near eyes or near pelvis that would create excessive imaging artifact
• Poorly controlled diabetes mellitus
• Patient receiving neoadjuvant endocrine therapy (due to low likelihood of complete response)
• Pregnancy or lactating female
• Substance abuse, medical, psychological, or social conditions that may interfere with the patient's participation in the study
• Evidence of distant disease on physical exam or initial imaging
• Medical conditions precluding chemotherapy or curative intent surgery
• Incarcerated or otherwise institutionalized at time of enrollment
