Quality of life findings from a multicenter, multinational, observational study of patients with metastatic hormone-refractory prostate cancer.

摘要

BACKGROUND: The assessment of health-related quality of life (HRQL) for patients with hormone-refractory prostate cancer (HRPC) is of paramount importance because new treatments have a modest impact on survival but side effects of treatment and disease symptoms can significantly impact HRQL. METHODS: This was an observational, non-interventional, multi-center, multi-national cohort study of patients with metastatic HRPC. Health-related quality of life was assessed using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ C30), the Functional Assessment of Cancer Therapy-Prostate (FACT-P) and the EQ-5D index. Mean changes from baseline to month 3, 6, and 9 were computed and tested using paired t-tests. RESULTS: FACT-P PCS, EQ-5D index and 10 of 14 EORTC domains were statistically significantly lower (P < 0.05) than the baseline scores at the 3, 6 and 9 month visits. The domains that did not reach statistical significance were cognitive functioning, insomnia, diarrhea and financial difficulties. CONCLUSIONS: These data demonstrate that patients with metastatic HRPC experience rapid, significant deterioration in HRQL, highlighting the need for effective palliative therapy for men with HRPC.
