Impact of breast cancer survivorship on quality of life in older women.

ABSTRACT

Quality of life (QOL) is an important outcome for cancer survivors; but although age is a major risk factor, most breast cancer survivorship studies are conducted with younger women. The objective of our study was to compare QOL in a sample of older breast cancer survivors to a sample of older women who were never diagnosed with breast cancer. A sample of 127 older breast cancer survivors as identified by a cancer registry was compared to a demographically equated sample of 87 older women participating in an epidemiological study. Both groups completed a questionnaire and participated in an interview to measure QOL. The older breast cancer survivors scored worse in the Medical Outcomes Study-Short Form, a measure of health-related QOL. Survivors reported no more depressive symptoms or anxious mood than the comparison group, but scored lower in measures of positive psychosocial well-being, including life satisfaction, mastery, and spiritual well-being, and reported more depressed mood and days affected by fatigue. Older breast cancer survivors show multiple indications of decrements in their health-related quality of life, and lower psychosocial well-being than the comparison group. These decrements may represent deficits in reserve capacity that predispose older cancer survivors to functional disability but may not be readily detected in typical clinical evaluations given the multiple impairments common in geriatric populations. Results suggest a need for greater attention to promoting functioning and psychological well-being among older cancer survivors, even when they may not have obvious cancer-related medical complications.
