diet and exercise interventions among men with prostate cancer (prostate 8-ii)

Conditions: Prostate Cancer

Summary: the prostate 8-ii study is a randomized controlled trial of testing different combinations of educational and supportive tools related to diet and exercise to evaluate biological, clinical, and quality of life outcomes in men choosing radical prostatectomy as treatment for prostate cancer.

this is a pi initiated, randomized controlled trial of four exercise and diet interventions among men opting for radical prostatectomy for prostate cancer. the prostate 8-ii study enrolls men up to 8 weeks prior to surgery and participants remain on study for 24 cycles after surgery (1 cycle=28 days). after obtaining written informed consent, enrolled subjects will be scheduled for the baseline assessments. all participants will receive group a educational materials and tools, but these will be distributed at different times based on group assignment. the other 3 groups will receive different combinations of exercise (group b), diet (group c) and exercise and diet (group d) tools. men in all arms will be asked to complete questionnaires at baseline, pre-surgery, and at cycles 6,12, \& 24 post-surgery, and complete blood and urine collection, diet recall, and accelerometer measurement at select time points. specimens from biopsy and radical prostatectomy will be reviewed by the investigators' collaborator, genomedx, for rna characterization and assessment of the genomic risk scores. participants will be followed for 30 days after completion of the 2-year 24-cycle intervention period or removal from the study, or until death, whichever occurs first for any treatment-related adverse events. following the completion of the intervention, participant's treatment and disease status will be collected on a yearly basis, for 3 more years.
