Microscopy Imaging of Whole-mount Stained Human Tissues
TumorBrain3 moreThe goal of this clinical trial is to develop an imaging platform for intraoperative tumor margin delineation in 250 cases of tumor-suffered patients. The main questions it aims to answer are: • to develop the protocol of rapid assessment of surgical specimens without need for fixation, embedding, and cryosectioning required for conventional histopathology. Participants will provide a small piece of their surgical specimens from tumor removal surgery . If there is a comparison group: Researchers will compare normal specimens to see if we can observe the difference.

Assessment of the Presence of Symptoms of End-of-life Discomfort and Their Management in Children...
Primary Brain TumorDespite medical advances, cancer remains the leading cause of death by disease in children. Brain tumors are the second most common cause of cancer in children after leukemia, representing 25% of pediatric cancers. The overall survival rate is about 50% with extremes ranging from less than 5% to more than 90% depending on the histological type of brain tumor. The end of life of children with a brain tumor is marked by the possibility of discomfort symptoms, painful or not, and by a progressive neurological deterioration, which makes the management of these children complex for both families and health professionals. Over the last decade, the concept of palliative care has been increasingly integrated into pediatric onco-hematology services with the primary objective of better symptom control in a global approach to the child and his or her family in order to aim at a better quality of life.
A Comprehensive Clinical fMRI Software Solution to Enable Mapping of Critical Functional Networks...
Brain TumorOur preliminary work demonstrates that an integrated fMRI software solution, incorporating tb-fMRI, rs-fMRI, and CVR mapping, is clinically feasible and helps clinicians plan brain tumor resection. We have developed a novel automated seed selection method that can accurately map language networks from rs-fMRI. We hypothesize that our innovative approach to enhance, optimize, and validate our preliminary software and integrate it with an established fMRI platform will create robust solutions for clinical RSN and CVR mapping. Partnering with NordicNeuroLab (NNL) will leverage the professional software development by a seasoned commercial MRI software producer in coordination with leading clinical and research experts at MD Anderson. The research will be conducted through three specific aims: Develop a clinical software platform for mapping RSNs and determine optimized workflow for presurgical localization of eloquent areas. Develop a clinical software platform for mapping CVR and determine optimized workflow for identifying and visualizing brain areas with potential false-negative fMRI results. Test and validate RSN and CVR mapping software in patients undergoing neurosurgery.

CBF and NCF Changes With Brain Radiation
Neurocognitive DysfunctionBrain MetastasesThis study will be a dual-arm prospective longitudinal cohort study for patients with brain metastases, at least one of which is appropriate for radiotherapy, to explore brain and cognitive changes following SRS or WBRT and evaluate the feasibility of a novel MRI protocol to identify potential radiological biomarkers of NCF decline. Patients diagnosed with brain mets will be assigned to either Arm A or Arm B, depending on their treatment plan. Patients in Arm A will be treated with SRS. Patients in Arm B will be treated with WBRT. Patients' neurocognitive function will be assessed before their radiation treatment and followed up for 2 years post treatment.
18F-FMAU PET/CT and MRI for the Detection of Brain Tumors in Patients With Brain Cancer or Brain...
Anatomic Stage IV Breast Cancer AJCC v8Clinical Stage IV Cutaneous Melanoma AJCC v818 moreThis early phase I trial tests the use of a radioactive tracer (a drug that is visible during an imaging test) known as 18F-FMAU, for imaging with positron emission tomography/computed tomography (PET/CT) in patients with brain cancer or cancer that has spread to the brain (brain metastases). A PET/CT scan is an imaging test that uses a small amount of radioactive tracer (given through the vein) to take detailed pictures of areas inside the body where the tracer is taken up. 18F-FMAU may also help find the cancer and how far the disease has spread. Magnetic resonance imaging (MRI) is a type of imaging test used to diagnose brain tumors. 18F-FMAU PET/CT in addition to MRI may make the finding and diagnosing of brain tumor easier.
PET Imaging of Patients With Melanoma and Malignant Brain Tumors Using an 124I-labeled cRGDY Silica...
Newly Diagnosed or Recurrent Metastatic Melanoma PatientsMalignant Brain TumorsCurrent tests to detect cancer, including CAT scans and MRI scans, are limited. PET scans use special dyes that are injected into a vein and can better localize possible cancer. The investigators have developed a new particle that can carry a radioactive dye to a very specific area of the tumor. When using a PET scan the radioactive dye can be viewed in areas of possible disease. This particle has been studied in mice and was safe. The particles will not treat the cancer and any images or information found during this study will not be used for your treatment. The information collected may be used to guide the design of future studies to detect and/or treat tumors.
Preclinical Brain Tumor Models
Brain MetastasesDiffuse GliomasBackground: Primary or secondary brain tumors (metastases) remain associated with a very poor prognosis linked to significant therapeutic resistance. Thus, glioblastoma, which is the most common and aggressive primary brain tumor in adults, is associated with inevitable relapses within 7 to 10 months and median survival of approximately 12 to 14 months. At the same time, brain metastases are increasingly increasing following better systemic control of other metastatic sites and improvement in detection methods. However, they remain resistant to the latest therapeutic innovations such as immunotherapies or targeted therapies. In this context, innovative strategies are necessary to identify new therapeutic targets and implement new treatments to overcome resistance phenomena in the clinic. Objective: Our goal will be to generate tumoroids and stem-like cell lines (PDX) from patient tumor samples. Methods: We will establish tumor tumoroids and stem cell lines from patient samples. These preclinical models will allow us to test a large number of drugs, quickly and efficiently thanks to models as close as possible to patient tumors and limiting the use of animal models (3R). Overall, this project should enable major advances in the treatment of glioblastoma and brain metastases and enable the rapid testing of new molecules in clinical trials thanks to the homology of our models with our patients' diseases.
