PURPOSE: The purpose of the study was to determine the relationship between life-stage variables (ie, age at diagnosis and years of survival) and quality-of-life (QOL) outcomes in long-term survivors of breast cancer. DESCRIPTION OF STUDY: In this cross-sectional study, 105 long-term survivors of breast cancer participated in a mailed survey assessing QOL. Participants were selected from a cancer center tumor registry using a stratified random-sampling procedure that was based on age at diagnosis. The Quality of Life-Cancer Survivors scale was used to assess QOL outcomes in the physical, psychological, social, and spiritual domains. RESULTS: Long-term survivors of breast cancer who had received diagnoses at an older age (> 65 years) showed significantly (P <.05) worse QOL outcomes in the physical domain, while those who had received diagnoses at a younger age (27-44 years) showed worse QOL outcomes in the social domain than other age groups. A nonlinear relationship was observed, with long-term survivors who had received diagnoses in middle age (45-65 years) showing better QOL outcomes in the physical domain and in overall QOL. Age at diagnosis and years of survival were significant predictors of QOL outcomes. CLINICAL IMPLICATIONS: These findings indicate that the life stage at diagnosis can help to predict long-term QOL outcomes in breast cancer survivors. Educational strategies to help oncology professionals develop a better understanding of the impact of age at diagnosis may be important in developing tailored interventions that respond to the specific needs of breast cancer survivors at each life stage.
