Impact Of Glioblastoma (Gbm)-Related Cognitive Dysfunction (Cd) On Caregiver Burden: Preliminary Results From Multi-Site Study In The Us

16Background: GBM is a largely incurable, highly aggressive cancer with high incidence of CD. Caregivers face heightened stress with loved one’s limited life expectancy and additional duties. To better understand this unique group, a survey tool was developed to examine effect of CD on caregiver burden. Methods: Four of 10 planned academic centers are enrolling towards achieving 200+ completed surveys.

Dyads with caregiver survey and respective patient’s clinical data are created as possible. Results: Complete data from 31 caregivers and 28 dyads enrolled at Huntsman Cancer Institute, University of Utah and University of California, Los Angeles are currently availa...
