Objective: This article examines the relative importance of cancer-related and noncancer illness factors as they predict the health quality of life among older adult, long-term cancer survivors. Specifically, it examines the effects that continuing cancer symptoms and comorbidities have on functional difficulties and how they in turn affect perceptions of disability and self-rated health.
Method: Data from an National Cancer Institute (NCI)-funded, tumor registry-based 10-year study of 321 older adult (age 60+), long-term (5+years post diagnosis) survivors of breast colorectal and prostate cancer are examined using regression analyses.
Results: The analyses documented the independent effects of both cancer-related and age-related health factors as they contribute to explaining functional difficulties, perceptions of disability and self-rated health. Gender and racial differences in health quality of life were also identified.
Discussion: The findings suggest that geriatricians, geriatric nurses, and clinical gerontologists who work with cancer survivorsneed to be aware of the ways in which both cancer and noncancer illness factors work together in producing threats to health quality of life through the extent and nature of functional impairments.
Keywords: cancer and aging; comorbidities; disability; health quality of life; physical function.
