Effects of skeletal morbidities on longitudinal patient-reported outcomes and survival in patients with metastatic prostate cancer.

Journal Article (Journal Article)

GOALS OF WORK: Patients with prostate cancer metastasized to bone frequently experience skeletal morbidities as a result of their disease. We sought to quantify the longitudinal effects on patient-reported outcomes of skeletal-related events (SREs) and to ascertain the declines in health-related quality of life (HRQOL) and pain experienced by patients who experienced SREs. MATERIALS AND METHODS: Data are from a clinical trial for the treatment of SREs associated with advanced prostate cancer metastatic to bone. Outcome measures included the Functional Assessment of Cancer Therapy-General (FACT-G) and the Brief Pain Inventory. Among patients who survived 6 months after randomization, patients with no SREs in the initial 6 months after randomization were matched via propensity scores with those experiencing one or more SREs. Similarly, patients with one SRE were matched with a subset of patients with two or more SREs. MAIN RESULTS: Patients with SREs in the initial period had significantly worse survival and HRQOL than those with no SREs. Significant differences were found between the pain differences, FACT-G total scores, and FACT-G physical, emotional, and functional subscales. Comparisons of patients with single vs multiple SREs showed similar patterns. CONCLUSIONS: The presence of SREs is significantly associated with worse survival and poorer HRQOL in this patient population. Increasing SRE intensity shows a pattern of increasingly decreased survival and poorer HRQOL.
