Background: Although androgen-deprivation therapy (ADT) is the foundation of treatment for prostate cancer, the physiological impacts of ADT result in functional decline and enhanced risk of chronic disease and metabolic syndrome.Purpose: The Individualized Diet and Exercise Adherence Pilot Trial (IDEA-P) is a single-blind, randomized, pilot trial comparing the effects of a group-mediated, cognitive-behavioral (GMCB) exercise and dietary intervention (EX+D) with those of a standard-of-care (SC) control during the treatment of prostate cancer patients undergoing ADT.Methods: A total of 32 prostate cancer patients (M age = 66.28, SD = 7.79) undergoing ADT were randomly assigned to the 12-week EX+D intervention (n = 16) or control (n = 16). The primary outcome in IDEA-P was change in mobility performance with secondary outcomes including body composition and muscular strength. Blinded assessment of outcomes were obtained at baseline and at 2- and 3-month follow-ups.Results: Favorable adherence and retention rates were observed, and no serious intervention-related adverse events were documented. Intent-to-treat ANCOVA controlling for baseline value and ADT duration demonstrated that EX+D resulted in significantly greater improvements in mobility performance (p < .02), muscular strength (p < .01), body fat percentage (p < .05), and fat mass (p < .03) at 3-month follow-up, relative to control.Conclusion: Findings from the IDEA-P trial suggest that a GMCB-based EX+D intervention resulted in significant, clinically meaningful improvements in mobility performance, muscular strength, and body composition, relative to controls. Collectively, these results suggest that the EX+D was a safe and well-tolerated intervention for prostate cancer patients on ADT. The utility of implementing this approach in the treatment of prostate cancer patients on ADT should be evaluated in future large-scale efficacy trials.Clinical Trial information: NCT02050906.
