Abstract Background: Patients with metastatic prostate cancer live with a considerable disease burden that may have a profound impact on physical activity and quality of life. This patient group may survive for many years after disease onset; however, there is little evidence on their habitual levels of physical activity. The aim of this study was to investigate physical activity levels and associated health-related quality of life in prostate cancer patients with bone metastases. Methods: ExPeCT (Exercise, Prostate Cancer and Circulating Tumour Cells: CTRIAL-IE 15-21) (ClincalTrials.gov identifier NCT02453139) is an ongoing multicenter trial examining the effect of a 6-month structured exercise intervention for patients with metastatic prostate cancer. Participants complete questionnaires examining self-reported health-related quality of life (FACT-P), sleep (Pittsburgh Sleep Index), depression (PHQ-9), and physical activity (Harvard Health Professionals Study Questionnaire) at baseline, three, and six months. Analysis of 3- and 6-month data is ongoing. Result: An interim analysis of the baseline outcome measures of 64 patients with bone metastases was completed (mean age 69.4 (SD 7.35) years and mean BMI 29.2 (SD 5.8) kg/m2). Median time since diagnosis was 34 months (IQR 7-54) and 55% (n=35) of participants had &amp;gt;1 region affected by metastatic disease. Preliminary data demonstrated that 38% (n=24) of participants did not meet the current aerobic exercise guidelines for cancer survivors. In total, 20% (n=13) of participants reported engaging in vigorous activity and 16% (n=11) reported completing resistance exercise. There was no correlation found between physical activity levels and quality of life (r=0.01), sleep (r=0.02), or depression (r=-0.15) scores. The majority of participants (61% (n=41)) had sleep scores of &amp;gt;7, indicative of poor sleep quality. Sleep scores correlated negatively with global quality of life (r =-0.55, p&amp;lt;0.05). Patients scored lowest in the “functional” and “additional prostate cancer-related concerns” domains of quality of life. Discussion: Findings highlight the association between reduced quality of life and poor sleep quality among men with metastatic prostate cancer. In addition, data suggest a high prevalence of suboptimal physical activity levels in this population. Patients with metastatic disease may benefit from lifestyle interventions that aim to increase physical activity levels.
