Filter by:This phase II trial studies whether low dose dexamethasone works as well as standard dose dexamethasone to reduce brain swelling after brain surgery in patients with primary brain tumors or cancer that has spread from other places in the body to the brain (metastatic). Surgery is an important part of the treatment of brain tumors; however, it results in injury to surrounding brain tissue, leading to brain swelling. Dexamethasone is effective for controlling the swelling of the brain; however, dexamethasone can cause many unwanted side effects. To minimize the side effects of dexamethasone, the lowest dose needed to control swelling of the brain should be used. This research study is assessing the safety of using a lower than standard dose of dexamethasone after the surgery to control brain swelling.
This phase I trial investigates the side effects of chemotherapy and cellular immunotherapy in treating children with IL13Ralpha2 positive brain tumors that have come back after a period of improvement (recurrent) or do not respond to treatment (refractory). Cellular immunotherapy (IL13(EQ)BBzeta/CD19t+ T cells) are brain-tumor specific cells that may induce changes in body's immune system and may interfere with the ability of tumor cells to grow and spread. Chemotherapy drugs, such as as cyclophosphamide and fludarabine, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Many patients with brain tumor respond to treatment, but then the tumor starts to grow again. Giving chemotherapy in combination with cellular immunotherapy may kill more tumor cells and improve the outcome of treatment.
This clinical trial examines the integration of cancer genetic testing in various ethnic populations. Studying individuals and families at risk of cancer may help identify cancer genes and other persons at risk. The information from this study may provide an opportunity for cancer risk stratification and individualized screening in these ethnic populations.
This exploratory study investigates how an imaging technique called 68Ga-FAPi-46 PET/CT can determine where and to which degree the FAPI tracer (68Ga-FAPi-46) accumulates in normal and cancer tissues in patients with cancer. Because some cancers take up 68Ga-FAPi-46 it can be seen with PET. FAP stands for Fibroblast Activation Protein. FAP is produced by cells that surround tumors (cancer associated fibroblasts). The function of FAP is not well understood but imaging studies have shown that FAP can be detected with FAPI PET/CT. Imaging FAP with FAPI PET/CT may in the future provide additional information about various cancers.
This phase II trial studies how well ¹⁸F- fluoromisonidazole (FMISO) works with positron emission tomography (PET)/magnetic resonance imaging (MRI) in assessing participants with malignant (cancerous) brain tumors. FMISO provides information about the oxygen levels in a tumor, which may affect how the tumor behaves. PET/MRI imaging produces images of the brain and how the body functions. FMISO PET/MRI may help investigators see how much oxygen is getting in the brain tumors.
The phase I/II trial studies the side effects and best dose of panitumumab-IRDye800 in diagnosing participants with malignant glioma who undergo surgery. Panitumumab-IRDye800 can attach to tumor cells and make them more visible using a special camera during surgery, which may help surgeons better distinguish tumor cells from normal brain tissue and identify small tumors that cannot be seen using current imaging methods.
