Memory Avoidance Whole Brain Radiotherapy vs Hippocampal Avoidance Whole Brain Radiotherapy (Athena 2 Trial)

Participants in this research study have cancer that has spread to their brain, called brain metastases. One treatment for this type of cancer is called whole brain radiotherapy that stays away from a specific neurocognitive substructure, called the hippocampus, combined with medication to preserve cognitive function. This study compares that approach to another approach of whole brain radiotherapy that stays away from additional structures that are thought to have a role in cognitive function. Researchers want to see if there is a difference in the preservation of cognitive function between these two approaches.

Neoadjuvant vs. Intraoperative vs. Adjuvant Resection Cavity Radiotherapy of Brain Metastases

Patients suffering from malignancies in advanced stages often develop brain metastases, which limit both the life span and the quality of life. Combining surgery and radiotherapy for resectable brain metastases is standard of care but there is a lot of controversy on which kind of radiotherapy is best suitable. Recently, first volumetric in-silico analyses point to theoretical advantages of neoadjuvant stereotactic radiotherapy of brain metastases. Special about this trial is the direct comparison between the three currently discussed radiotherapy options for resectable brain metastases: Neoadjuvant stereotactic radiotherapy, intraoperative radiotherapy and adjuvant stereotactic radiotherapy.

Stereotactic Radiosurgery Compared With Hippocampal-Avoidant Whole Brain Radiotherapy (HA-WBRT) Plus Memantine for 5 or More Brain Metastases

Stereotactic radiosurgery (SRS) is a commonly used treatment for brain tumors. It is a one-day (or in some cases two day), out-patient procedure during which a high dose of radiation is delivered to small spots in the brain while excluding the surrounding normal brain. Whole brain radiation therapy with hippocampal avoidance (HA-WBRT) is when radiation therapy is given to the whole brain, while trying to decrease the amount of radiation that is delivered to the area of the hippocampus. The hippocampus is a brain structure that is important for memory. Memantine is a drug that is given to help relieve symptoms that can be caused by WBRT, including problems with memory and other mental symptoms. Health Canada, the regulatory body that oversees the use of drugs in Canada, has not approved the sale or use of memantine in combination with WBRT to treat this kind of cancer, although they have allowed its use in this study.

Development of MRF for Characterization of Brain Tumors After Radiotherapy

The purpose of this study is to discover the potential convenience and ease of using a Magnetic Resonance Imaging (MRI) technique, named Magnetic Resonance Fingerprinting (or MRF), to achieve high-quality images within a short scan time of 5 min for viewing the entire brain. This is an advanced quantitative assessment of brain tissues. This method is being applied with IVIM MRI to be able to tell the difference between a brain with radiation necrosis and a brain with tumor recurrence. Participants will consist of individuals who have received radiation therapy in the past and were diagnosed with radiation necrosis, individuals with recurrent tumors, individuals with previously untreated tumors, and healthy individuals who have no brain diseases and have not had radiation treatment to the brain. Participants will undergo an MRI scan at a one-time research study visit; no extra tests or procedures will be required for this research study. The primary objectives of this study are: * To demonstrate the clinical feasibility of combining MRF with state-of-the-art parallel imaging techniques to achieve high-resolution quantitative imaging within a reasonable scan time of 5 min for whole brain coverage. * To apply the developed quantitative approach in combination with IVIM MRI for differentiation of tumor recurrence and radiation necrosis. * To investigate the effect of radiation dose on the development of radiation necrosis and tumor recurrence.

ioMRI in the Surgery of Brain Metastases.

The study aims to improve the surgical treatment of brain metastases through the use of advanced imaging techniques. The investigators are examining how intraoperative MRI (iMRI) can aid surgeons in precisely locating and removing tumors, with the potential to enhance surgical outcomes and reduce the need for additional procedures. While iMRI offers the promise of better tumor visualization during surgery, it is also associated with longer surgical times and may carry the risk of increased complications. This study seeks to carefully evaluate these aspects to determine the overall benefits and challenges of iMRI in brain metastasis surgeries. The ultimate aim is to enhance treatment effectiveness and improve recovery and health outcomes for participants dealing with brain metastases.

Measuring and Mapping Cognitive Decline After Brain Radiosurgery

Background Stereotactic Radiosurgery (SRS) is a localised radiotherapy treatment for patients with brain metastases or other benign tumours in the brain, like meningiomas. The Investigators do not currently know if, or how much, SRS affects brain function. Patients with brain tumours do not get tested routinely for their brain function. Understanding short- and long-term side-effects is important for SRS. Brain metastases patients have short life expectancies (6-months to 1-year). However, meningioma patients can live 10 years or more. SRS is used to treat both. The Montreal Cognitive Assessment will be used to test the participants' brain function. Quality-of-life questionnaires QLQ-C30 and BN20 will also be used to assess the participants' physical and mental wellbeing . These are specific for patients with brain cancer. Why is it important This study aims to identify areas in the brain that relate to changes in brain function after SRS. These areas can then have the radiation dose reduced to them in future patients, hoping to minimise side-effects. Research Question Which regions of the brain contribute to a decline in brain function following SRS. Study Design This is a single centre observational study with prospective and retrospective collection of data. This study will look at two groups of patients: Group1: Patients will complete the MoCA and two quality-of-life questionnaires before the treatment and every 3 months for a year. Group2: Patients will complete the MoCA and two quality-of-life questionnaires once. The investigators will use these tests, MRI scans and the SRS treatment plan to identify areas of the brain that are responsible for any problems with the participants' brain function. The participants for Group 1 will be recruited from the SRS Clinics, at City Campus, Nottingham University Hospitals NHS Trust. The participants for Group 2 will be identified through the Mosaiq Oncology Information System. This pilot study is funded by the Midlands Mental Health and Neurosciences Network.
