简要总结
The purpose of this study is to compare two different imaging methods to examine the response of brain metastases to WBRT. These two imaging methods will take pictures of the brain using : 1) a positron emission tomography (PET) scanner and 2) Magnetic Resonance Imaging (MRI) scanner. A PET scanner resembles a CT or MR scanner.PET scans use radioactive substances also called as radioactive markers to "see" cancer cells. We plan to use [18F]FLT as a radioactive marker. FLT is used to image tumor growth. FLT PET scan is a new clinical procedure. It is in the testing stage of development unlike FDG-PET which is used more commonly used. Therefore, this is considered a "research" study. This will help us evaluate whether this scan will be safe and better used in the future to evaluate tumors. The amount of radiation to the body is small. The radiation from the radiotracer drug will be gone from the body in a few hours. There is no radiation risk from the MRI scans. Additionally, we also plan to use MRI imaging of the brain. We expect that [18F]FLT PET is better when compared to MRI and will give us more information about the brain metastases after WBRT.

入选标准
- •Histologically-confirmed (confirmation done at MSKCC) metastatic adenocarcinoma of the breast
- •Radiologic evidence of new and/or progressive brain metastases ((≥10 mm in longest dimension) by MRI imaging of the Brain
- •Planned WBRT based on number (≥ 3 lesions) and/or size (≥ 1 cm) of brain metastases.
- •Age ≥18 years; males and females
- •Patients who require additional clinically indicated stereotactic radiosurgery (SRS) in addition to WBRT will also be eligible.
- •Life expectancy of >12 weeks.
- •Karnofsky Performance Status (KPS) ≥ 70%.
- •Creatinine ≤2.0 times the upper limit of normal.
- •Women of childbearing potential must have a negative serum pregnancy test performed within 7 days prior to enrollment, must be non-lactating and must agree to use adequate contraception prior to enrollment and for the duration of study participation.
- •No limit to prior therapies with last anti-cancer treatment ≥2 weeks from initiation of WBRT. Please note: there is no washout period required for trastuzumab, pertuzumab, for patients who have developed new parenchymal brain metastases while on these agents.
排除标准
- •Leptomeningeal metastases Please note: leptomeningeal metastases may be allowed if it is limited to cranial metastasis (MRI spine should be completed, within 4 weeks of enrollment, to show that no other leptomeningeal metastases is present) and is not the only metastasis present in the brain.
- •Concurrent administration of lapatinib or other tyrosine kinase inhibitors other than sorafenib
- •Craniotomy or any other major surgery, open biopsy, or significant traumatic injury within 4 weeks of randomization.
- •Concurrent anti-cancer therapy (chemotherapy, hormonal therapy, radiation therapy, surgery, immunotherapy, biologic therapy, or tumor embolization) other than sorafenib, and protocol-specified whole-brain radiotherapy.
- •Use of any investigational drug within 30 days or 5 half-lives, whichever is longer, preceding enrollment.
- •Inability to comply with protocol and /or not willing or not available for follow-up assessments.
- •Any condition which in the investigator's opinion makes the patient unsuitable for the study participation.
- •Patient is incontinent of urine or stool (which would make them unable to tolerate lying still for 60 minutes).
- •Claustrophobia
- •Known allergic reaction to Gd-DTPA
- •Renal insufficiency with recent (<3 month old) creatinine >2.0
