Effect of a Home-based Walking Intervention on Cardiopulmonary Fitness and Quality of Life Among Men with Prostate Cancer on Active Surveillance: The Active Surveillance Exercise Randomized Controlled Trial

Year: 2023

Type: article

Study designs: Randomized Controlled Trial, Clinical Trial

Abstract: BACKGROUND: Active surveillance (AS) is standard care for most men with low-risk prostate cancer (PC); yet, many men on AS eventually undergo curative therapy. Interventions to lower the risk of cancer progression and fear of recurrence among men on AS for PC are needed. OBJECTIVE: To determine the effect of aerobic exercise on cardiorespiratory fitness, body size, and quality of life (QOL) among men on AS for PC. DESIGN, SETTING, AND PARTICIPANTS: We conducted a 1:1 randomized controlled trial among 51 men with low-risk PC who elected AS. Participants were enrolled at the University of California, San Francisco. INTERVENTION: The 16-wk intervention included a home-based walking program with a nonlinear exercise prescription tailored to baseline fitness level, heart rate monitor, and weekly phone call with an exercise physiologist. Controls received printed materials. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: peak; secondary outcomes included change in body size, anxiety, and QOL. Analyses were based on intention to treat. RESULTS AND LIMITATIONS: peak than the control group (31.9 ± 4.7 vs 27.2 ± 4.8 ml/kg/min; group × time effect p value: <0.001). Additionally, the intervention group reported less fear of PC recurrence and urinary obstruction/irritation, while controls reported more of these two QOL measures, from 0 to 16 wk (p = 0.04 and 0.03, respectively). Two participants discontinued the intervention, including one due to knee pain related to the study. CONCLUSIONS: peak and reduced urinary obstruction/irritation and fear of recurrence among men on AS for PC. PATIENT SUMMARY: Moderate to vigorous aerobic exercise improves fitness and quality of life among men on active surveillance for prostate cancer.
