Cerebral Metastases Patients clinical trials

Neurococognitive and Functioal Assessment of Patients With Brain Metastases

The investigators seek to perform an observational study in patients with brain metastases that are to undergo whole brain radiation therapy (WBRT) or stereotactic radiosurgery (SRS) treatment in order to quantify any baseline neurocognitive changes which may result from intracranial disease burden, from radiation treatment (WBRT or SRS), or both. To do so, the investigators will compare matched control subjects to patients at time points obtained before and after radiation treatment with either SRS or WBRT. Pre-treatment evaluation will include neurocognitive testing and an assessment of fMRI task-related activation patterns and resting state brain activity. Four and twelve month post-treatment neuropsychological evaluations will be performed and pre- and 4-month post-treatment fMRI scans will be obtained in order to evaluate changes in neurocognitive functioning with a focus on short-term memory and executive function domains. A brief quality of life assessment will also be completed at each study time point. In order to plan treatment strategies in the future it is important to accurately document the effects of intracranial disease burden as well as radiation treatment on neurocognitive functioning, validate fMRI activation tasks for short term memory and executive functioning, and quantify the activation volumes that would potentially be spared in future "cognitive sparing" protocols. The investigators hypothesize first that the amount and location of intracranial disease burden will represent pre-treatment variables that affect NCF. The compromised NCF will be visualized in both the resting state and task-oriented neurocognitive exercise. The investigators anticipate that any perturbation in resting state caused by intracranial disease burden should be reflected in patients when compared to matched controls. The investigators hypothesize additionally that cancer patients with brain metastases undergoing radiation treatments will have improved intracranial disease control at the expense of executive and memory function with differences between patients that undergo stereotactic radiosurgery or whole brain radiation alone.
