Objectives: To provide an overview on the role of family caregivers (FCGs) in the care of older adults with cancer and review quality of life needs for FCGs. Data Sources: Journal articles, research reports, state of the science papers, position papers, and clinical guidelines from professional organizations were used. Conclusion: The high prevalence of multiple comorbidities and the associated burden of geriatric events in older adults have a substantial impact on the quality of life of their FCGs. Practical and efficient models of comprehensive assessment, interventions, and caregiving preparedness support are needed to improve outcomes for both older adults with cancer and their FCGs. Implications for Nursing Practice: Oncology nurses practicing in clinical and research settings have a responsibility to prepare themselves with evidence-based knowledge and resources to include the needs of FCGs in the care provided to older adults with cancer.
