Factors affecting health-related quality of life in women with recurrent breast cancer in Korea

PURPOSE: The purpose was to determine the effects of recurrent breast cancer on health-related quality of life (HRQOL). METHODS: We administered the European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30 and QLQ-BR23, McGill Quality of Life Questionnaire (MQOL), Beck Depression Inventory (BDI), and Brief Fatigue Inventory (BFI) to 152 women experiencing recurrence 1 year after being diagnosed with stage I to III breast cancer. We classified recurrent women as post-, ongoing-, and non-treatment group and performed multivariate-adjusted analyses in HRQOL comparisons with data available from disease-free survivors and general population. RESULTS: Groups not completing treatment were more symptomatic and had poorer functioning in HRQOL than the post-treatment group. Compared to the general population, the post-treatment group showed worse scores concerning role, cognitive, and social functioning, fatigue, and financial difficulties. The post-treatment group showed identical scores to disease-free survivors in most HRQOL domains; however, they reported less fatigue and depression than the disease-free group. Higher overall QOL was related to absence of comorbidity, completing treatment, being involved in decision making, no problems before surgery, and good overall medical care. CONCLUSION: Treatment completed, most degraded aspects of HRQOL in recurrent breast cancer women can return to levels observed in disease-free survivors.
