Filter by:Contrast-enhanced magnetic resonance imaging is the most widely used examination for detecting the presence of brain metastasis. Functional sequences such as perfusion weighted imaging makes it possible to differentiate tumor recurrence from cerebral radionecrosis. However, this imaging technique may exhibit limitations, especially for brain lesions consisting of a mixture of necrotic tissue and tumor progression or depending on the location of the lesion in the brain. The use of 18F-DOPA PET is another option available to oncologists. Many studies on gliomas showed the superiority of this imaging technique over contrast-enhanced MRI. However, this imaging solution has been very poorly studied for brain metastases. The new PET technology equiped with silicon detectors makes it possible to obtain greater sensitivities than those of previous generations. It also make possible to obtain images in very short acquisition times. After injection, the hardware allows to obtain the perfusion kinetics of the lesion thanks to a very short temporal sampling (i.e. three seconds). The main objective of this pilot study is to evaluate the association between early activity measurements (< 4 minutes post-injection) of 18F-FDOPA in PET and the differential diagnosis between radionecrosis and recurrence of cerebral metastases treated by radiotherapy.
Transcranial focused ultrasound (tFUS) offers a platform for non-invasive imaging and treatment of the brain and pathology of the brain -- allowing high resolution imaging in both spatial and temporal dimensions. Compared with the gold- standard for brain imaging, magnetic resonance imaging (MRI), ultrasound offers reduced contrast while providing improved sampling in time through a significantly more cost-effective approach. In addition, while MRI is used to guide invasive treatments, only ultrasound can offer treatments through three primary mechanisms: 1) neuromodulation, 2) blood brain barrier modulation, and thermal/mechanical ablation through high intensity focused ultrasound (HIFU). All three treatment options require targeting therapy through the skull, which remains a barrier to clinical translation. This proposal is to test the feasibility of acquiring noninvasive targeting imaging intraoperatively prior to clinically indicated cranial neurosurgery. By acquiring volumetric ultrasound images while coregistered to previously obtained stereotactic magnetic resonance imaging, the study will be able to compare the ability of tFUS to identify and focus on brain pathology.
This clinical trial is aimed at the evaluation of the safety and clinical activity of tiragolumab in combination with carboplatin, pemetrexed and atezolizumab in the first line treatment of metastatic non-squamous NSCLC patients with asymptomatic untreated brain metastases.
The purpose of this study is to determine whether a 16-week virtual, home-based, high-intensity interval training (HIIT) exercise program will improve physical, cognitive, and emotional health among young adult survivors of pediatric brain tumors. The names of the study interventions involved in this study are/is: - High-Intensity Interval Training (HIIT)
This study seeks to determine the impact of focused ultrasound (FUS) on the composition of the tumor extracellular microenvironment. Researchers will evaluate regions that are very abnormal, as well as regions that have less evidence of disease. A sub-portion of each of these areas will be targeted by focused ultrasound. Microdialysis catheters will then be placd into each region that has and has not been exposed to FUS (total of 4 catheters) to determine how FUS impacts the the brain and tumor extracellular metabolome, including concentration of routine drugs systemically administered prior to, and during surgery. Researchers hope that this information will help reveal the relative contribution of blood-derived compounds to the tumor microenvironment. If successful, microdialysis could be leveraged in the future to simultaneously evaluate pharmacokinetic and pharmacodynamic impacts of future candidate therapies, including those delivered with the aid of FUS.
This will be the first in-depth study to evaluate pretreatment and 12 months post-treatment, neurocognitive and psychological outcomes of children with brain tumor and blood cancer in Pakistan. The investigators will also determine the socioeconomic burden of pediatric brain tumors in low middle-income region and the association of micro RNA and protein markers with neurocognitive outcomes in PBT and blood cancer children. A prospective cohort study with a follow-up of 12 months at the Aga Khan University Hospital, Karachi, Pakistan and Jinnah postgraduate Medical Centre , Karachi, Pakistan will be conducted. After taking consent/ assent the investigators will recruit 80, 5-21 years old children with newly diagnosed brain tumors presenting with any stage, who have not undergone any treatment. Trained psychologist will assess the neurocognitive outcomes by the Slosson scale, Raven's progressive matrices and Wechsler Intelligence Scale for children (WISC V) and Wechsler Adult Intelligence Scale (WAIS-IV) tools. The Quality of life and depression of the children will be determined by PedQL and Revised Children's Anxiety and Depression Scale (RCADS) and hospital anxiety and depression scale (HADs) respectively . The financial burden of the disease on the family will be measured on a visual analog scale ranging from no burden (0) to very large burden (100) and the parents QoL and disrupted schedule, financial problems, lack of family support, health problems and the impact of caregiving on caregiver's self-esteem will be assessed by Pediatric Quality of Life Inventory PedQl (family module) and Caregiver Reaction Assessment (CRA) tools respectively. The serum micro RNA (mi-21, mi-10b and mi-210) and protein markers (GFAP, NSE and S100β) will be assessed by qRT-PCR and ELISA.
To learn if giving nivolumab in combination with relatlimab can help to control melanoma that has spread to the brain (melanoma with brain metastases). The safety and side effects of the study drug combination will also be studied.
This study is designed to see if we can lower the chance of side effects from radiation in patients with breast, kidney, small cell lung cancer, non-small cell lung cancer or melanoma that has spread to the brain and who are also being treated with immunotherapy, specifically immune checkpoint inhibitor (ICI) therapy. This study will compare the usual care treatment of single fraction stereotactic radiosurgery (SSRS) given on one day versus fractionated stereotactic radiosurgery (FSRS), which is a lower dose of radiation given over a few days to determine if FSRS is better or worse at reducing side effects than usual care treatment.
To learn if the combination of niraparib and dostarlimab can help to control advanced cancer that has spread to the brain.
The objective of the International Rare Brain Tumor Registry (IRBTR) is to better understand rare brain tumors through the collection of biospecimens and matched clinical data of children, adolescents, and young adult patients diagnosed with rare brain tumors.
