Overview
The purpose of this study is to improve outcome of breast cancer patients who develop brain metastases. This will investigate the benefits of early detection of brain metastases using brain imaging. In patients diagnosed and currently being treated for advanced or metastatic breast cancer, current guidelines do not recommend routine brain imaging. However, there is emerging evidence suggesting that patients diagnosed without symptoms of brain metastases may have a better outcome than those with symptoms such as headache, vomiting and weakness. In current practice, if signs and symptoms suggestive of brain metastases are to develop, then the doctor will arrange imaging of the brain, which may be a computerised tomography (CT scan) and/or a magnetic resonance imaging (MRI) scan. Should brain metastasis be detected, local radiotherapy, chemotherapy or targeted treatments will be offered. When initially diagnosed with metastatic or advanced breast cancer, participant will or would have undergone a brain scan by either MRI or CT during normal standard full-body CT scan (chest, abdomen and pelvis) imaging. In this study, each time participants have a regular full-body CT scans to assess treatment progress, they will also have an additional CT scan of the brain. Participants will have a total of 12 extra brain scans, with scans taking place every three months for the first 2 years, and every 6 months for the following years. These scans will occur at the same location as your current treatment. There will be no extra costs involved in the study and participants will be in the study for 4 years and following their follow-up details will be collected from medical records. Some participants who develop brain metastases during the followup will have neurosurgery to remove these metastases. The investigators will collect either fresh or archived tissues and a cerebrospinal fluid (CSF) sample at the time of surgery from those patients. If the treating investigators do not think neurosurgery is an option, they will ask participants to have a lumbar puncture for the collection of CSF. The purpose of this optional CSF collection is to take a liquid biopsy to check for markers (or biomarkers) potentially expressed by the breast cancer tumour cells in the brain. Participants will also be asked to provide a blood sample as well as old tumour from breast surgery (other metastatic tumour tissue). The information obtained from this component of the study will not impact a parcipants current management, but it will help researchers to develop better treatments for breast cancer brain metastases in the future.
