Quality of life of irradiated brain tumor survivors treated with donepezil or placebo: Results of the WFU CCOP research base protocol 91105
Abstract
The health-related quality of life (HRQL) and fatigue of brain cancer survivors treated with donepezil or placebo for cognitive symptoms after radiation therapy were examined. One hundred ninety-eight patients who completed >30 Gy fractionated whole or partial brain irradiation at least 6 months prior to enrollment were randomized to either placebo or donepezil (5 mg for 6 weeks followed by 10 mg for 18 weeks) in a phase 3 trial. A neurocognitive battery, the Functional Assessment of Cancer Therapy-Brain (FACT-Br) and the Functional Assessment of Chronic Illness Therapy (FACIT)-fatigue, was administered at baseline, 12 weeks, and 24 weeks. At 12 weeks, donepezil resulted in improvements in only emotional functioning (P = .04), with no significant effects at week 24. Associations by level of baseline cognitive symptoms (above or below the median score of the baseline FACT-Br "additional concerns/brain" subscale), indicated that participants with more baseline symptoms who received donepezil versus placebo, showed improvements in social (P = .02) and emotional well-being (P = .038), other concerns/brain (P = .003) and the FACT-Br total score (P = .004) at 12 weeks, but not 24 weeks. However, participants with fewer baseline sympt...Continue Reading
