Cognitive Biomarkers in Pediatric Brain Tumor Patients

2016-09-26 22:23:22 | BioPortfolio


The investigators will focus on two cohorts of brain tumor patients aged, 4-18 years, to answer two critical questions: 1) Can the investigators acquire high quality data relevant to cognitive function during the peri-diagnostic period and, 2) can the investigators develop predictive models for cognitive outcomes using serial examination of functional imaging and cognitive function. Any patient with a newly diagnosed brain tumor aged 4-18 will be eligible for enrollment in cohort 1. Only patients with previously diagnosed tumors of the posterior fossa will be eligible for cohort 2. The rationale for of the focus on these patients is that first, the posterior fossa is the most common location for pediatric brain tumors and therefore this focus will impact the largest segment of this patient population. Second, three tumors commonly occur here, medulloblastoma, ependymoma and pilocytic astrocytoma. These are treated with surgery, radiation and chemotherapy (medulloblastoma), surgery and radiation therapy (ependymoma) or surgery only (pilocytic astrocytoma). Thus, this focus will provide a platform to analyze the impact that different tumor types and different standard treatments have on cognitive dysfunction. Finally, the fact that all subjects will have tumors of the same brain region will control for the effect that tumor location will have on cognitive testing and rsfcMRI. Here, repeated evaluations on and off therapy will provide the necessary data points to establish trajectories of cognitive development and recovery in this population.

Medical and Biotech [MESH] Definitions

A cytologic technique for measuring the functional capacity of tumor stem cells by assaying their activity. It is used primarily for the in vitro testing of antineoplastic agents.

A rare but highly lethal childhood tumor found almost exclusively in infants. Histopathologically, it resembles RHABDOMYOSARCOMA but the tumor cells are not of myogenic origin. Although it arises primarily in the kidney, it may be found in other parts of the body. The rhabdoid cytomorphology is believed to be the expression of a very primitive malignant cell. (From Holland et al., Cancer Medicine, 3d ed, p2210)

A malignant kidney tumor, caused by the uncontrolled multiplication of renal stem (blastemal), stromal (STROMAL CELLS), and epithelial (EPITHELIAL CELLS) elements. However, not all three are present in every case. Several genes or chromosomal areas have been associated with Wilms tumor which is usually found in childhood as a firm lump in a child's side or ABDOMEN.

Vegetative state refers to the neurocognitive status of individuals with severe brain damage, in whom physiologic functions (sleep-wake cycles, autonomic control, and breathing) persist, but awareness (including all cognitive function and emotion) is abolished.

Detection of or testing for certain ALLELES, mutations, genotypes, or karyotypes that are associated with genetic traits, heritable diseases, or with a predisposition to a disease, or that may lead to the disease in descendants. It includes prenatal genetic testing.
