Spouse caregivers of patients with advanced cancer are a high-risk population for depression. Subjective caregiving burden and relational variables, such as caregivers' attachment orientations and marital dissatisfaction, are important predictors of caregiver depression.

Depressive symptoms in advanced cancer patients are relatively common and may arise as a final common pathway of distress in response to psychosocial vulnerabilities, physical suffering, and proximity to death. These findings support the need for an integrated approach to address emotional and physical distress in this population and to determine whether early intervention may prevent depression at the end of life.
