Factors influencing quality of life in adult patients with primary brain tumors

Abstract

We performed a literature review with respect to factors influencing health-related quality of life (QOL) in adults with primary brain tumors. A comprehensive, peer-reviewed literature search was performed including studies examining QOL in adults with high-grade gliomas and low-grade gliomas and in routine neuro-oncology practice. The interpretation and implication of QOL domain scores may be different in high-grade, low-grade, and benign brain tumors. Several patient-related, treatment-related, and sociocultural factors influence QOL scores. Pretreatment baseline QOL domain scores have been shown to be a predictive parameter for survival function. Implementation of QOL scores in routine clinical practice is underused. QOL is an important outcome measure in the treatment of patients with brain tumors and should be incorporated as a surrogate end point along with traditional end points, such as disease-free and overall survival in most current trials.
