Purpose This prospective longitudinal study evaluated the effect of androgen deprivation therapy (ADT) on objective and self-reported physical function. Patients and Methods Men with nonmetastatic prostate cancer (PC) starting continuous ADT were enrolled in this matched cohort study. Physical function was assessed with the 6-minute walk test (6MWT), grip strength, and the timed-up-and-go (TUG) test, representing endurance and upper and lower extremity strength, respectively. Quality of life (QOL) was measured with the Medical Outcomes Study Short-Form 36 (SF-36) questionnaire. Subjects were assessed at baseline, 3, 6, and 12 months. Two control groups (PC without ADT; no PC), matched on age, education, and baseline function were enrolled. Mixed effects regression models were fitted, adjusting for baseline covariates. Results We enrolled 87 patients on ADT, 86 PC controls, and 86 healthy controls; groups were similar in age (mean, 69.1 years; range, 50 to 87) and physical function. The 6MWT distance remained stable in the ADT group (P = .96) but improved in both control groups (P < .05). Grip strength declined in the ADT group (P = .04), remained stable in PC controls (P = .31), and improved in healthy controls (P = .008). TUG scores remained stable over time and across groups (P > .10). The SF-36 physical function summary score declined in the ADT group (P < .001), but increased in both control groups (P < .001). Negative effects on outcomes were observed within 3 months of starting ADT and were generally independent of age. Conclusion Endurance, upper extremity strength, and physical components of QOL are affected within 3 months of starting ADT. Up-front exercise interventions to counteract these losses are warranted.

9526 Background: Although prolonged use of ADT is hypothesized to adversely affect physical function, few studies have examined this relationship longitudinally using objective measures of physical function. Methods: Men age 50+ with non-metastatic prostate cancer (PC) starting continuous ADT were enrolled in this prospective longitudinal matched cohort study. Physical function was assessed with the six-minute walk test (6MWT), grip strength, and the Timed Up and Go (TUG) test, representing endurance, upper extremity strength, and lower extremity strength, respectively. Self-reported physical function was measured with the Medical Outcomes Study SF-36. Assessments were done at baseline, 3 months, 6 months, and 12 months. Two control groups, matched on age, education, and baseline function were also enrolled. One control group had PC but did not receive ADT, and the other group did not have PC. Linear mixed effects regression models were fitted adjusting for baseline covariates. Results: 85 patients on ADT, 86 PC controls, and 86 healthy controls were enrolled. All 3 groups were similar in age (mean age 69.1 y, range 50–87) and physical function (all ANOVA p>0.05). The 6MWT distance improved in both control groups (p=0.05 and 0.05 for PC and healthy controls, respectively) but remained stable in the ADT group (p=0.96)). Grip strength declined in the ADT group (p=0.04), remained stable in the PC control group (p=0.31), and improved in the healthy control group (p=0.008). TUG scores remained stable over time and across groups (p>0.10). SF-36 physical function declined in the ADT group (p<0.001) but increased in both control groups (p<0.001). Negative effects on outcomes were noted within 3–6 months of starting ADT and were larger with older age. Conclusions: Endurance, upper extremity strength, and self-reported physical function are affected within 3–6 months of starting ADT, particularly in older men. Declines persist at 12 months after adjustment for baseline function and covariates. Exercise intervention studies to counteract these losses are warranted. No significant financial relationships to disclose.

Purpose Androgen-deprivation therapy is a commonly used treatment for men with prostate cancer; however, the adverse effects can be detrimental to patient health and quality of life. Exercise has been proposed as a strategy for ameliorating a range of these treatment-related adverse effects. We conducted a systematic review of the literature regarding the effects of exercise on treatment-related adverse effects in men receiving androgen-deprivation therapy for prostate cancer. Methods An online electronic search of the Cochrane Library, EMBASE, MEDLINE, CINAHL, SPORTDiscus, and Health Source databases was performed to identify relevant peer-reviewed articles published between January 1980 and June 2013. Eligible study designs included randomized controlled trials as well as uncontrolled trials with pre- and postintervention data. Information was extracted regarding participant and exercise intervention characteristics as well as the effects of exercise on bone health, body composition, physical performance, cardiometabolic risk, fatigue, and quality of life. Results Ten studies were included, with exercise interventions involving aerobic and/or resistance training. Exercise training demonstrated benefits in muscular strength, cardiorespiratory fitness, functional task performance, lean body mass, and fatigue, with inconsistent effects observed for adiposity. The impact of exercise on bone health, cardiometabolic risk markers, and quality of life are currently unclear. Conclusion Among patients with prostate cancer treated with androgen-deprivation therapy, appropriately prescribed exercise is safe and may ameliorate a range of treatment-induced adverse effects. Ongoing research of high methodologic quality is required to consolidate and expand on current knowledge and to allow the development of specific evidence-based exercise prescription recommendations.
