Abstract
PURPOSE
It is unclear whether life-expectancy estimates of patients with advanced cancer and their caregivers are associated with patient existential, social, or emotional quality of life (QOL) or caregiver emotional QOL.
METHODS
Patients with advanced cancer and their caregivers (n = 162 dyads) reported estimates of the chance the patient would live for 2 years or more from 0% (most pessimistic) to 100% (most optimistic). They also completed self-report measures of QOL.
RESULTS
Adjusting for sociodemographic confounds and multiple comparisons, more pessimistic caregiver and patient life-expectancy estimates were associated with worse caregiver emotional QOL and worse patient existential QOL. Discrepancies between patient and caregiver estimates were not associated with patient or caregiver QOL.
CONCLUSIONS
Pessimistic life-expectancy estimates are associated with worse existential QOL in patients and worse emotional QOL in caregivers. Prospective research to establish causal relationships is needed, and interventions to address the relationship between beliefs about life expectancy and existential and emotional QOL should be considered. Providing these interventions to patients and caregivers receiving information on life expectancy may mitigate the negative impact of life-expectancy information on patient existential quality of life.
