Abstract

PURPOSE: Treatment of prostate cancer with androgen deprivation therapy (ADT) is associated with an increased fat mass, decreased lean mass, increased fatigue and a reduction in quality of life (QoL). The aim of this study was to evaluate the efficacy of a 6-month dietary and physical activity intervention for prostate cancer patients receiving ADT, to help minimise these side effects.

METHODS: Patients (n = 94) were recruited to this study if they were planned to receive ADT for prostate cancer for at least 6 months. Men randomised to the intervention arm received a dietary and exercise intervention, commensurate with UK healthy eating and physical activity recommendations. The primary outcome of interest was body composition; secondary outcomes included fatigue, QoL, functional capacity, stress and dietary change.

RESULTS: The intervention group had a significant (p < 0.001) reduction in weight, body mass index and percentage fat mass compared to the control group at 6 months; the between-group differences were -3.3 kg (95 % confidence interval (95 % CI) -4.5, -2.1), -1.1 kg/m(2) (95 % CI -1.5, -0.7) and -2.1 % (95 % CI -2.8, -1.4), respectively, after adjustment for baseline values. The intervention resulted in improvements in functional capacity (p < 0.001) and dietary intakes but did not significantly impact fatigue, QoL or stress scores at endpoint.

CONCLUSIONS: A 6-month diet and physical activity intervention can minimise the adverse body composition changes associated with ADT.

IMPLICATIONS FOR CANCER SURVIVORS: This study shows that a pragmatic lifestyle intervention is feasible and can have a positive impact on health behaviours and other key outcomes in men with prostate cancer receiving ADT.
