Concordance of patient and caregiver reports in evaluating quality of life in patients with malignant gliomas and an assessment of caregiver burden.

Despite minor discrepancies in caregiver assessments of patient QOL relative to patient self-reports, our results suggest that the caregiver assessments can serve as adequate proxies for patient reports. Our results also illustrate the particularly heavy burden faced by caregivers of patients with malignant glioma. Further research into both of these areas is warranted.
