简要总结
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.
详细描述
PRIMARY OBJECTIVE:
I. To examine the effects of 2-year exercise and/or diet interventions on time to prostate-specific antigen (PSA) recurrence after RP.
SECONDARY OBJECTIVES:
I. Assess the proportion of participants with PSA recurrence at 6-, 12-and 24-months post-surgery.
II. To examine quality of life (QOL) across intervention groups over time. Outcomes will include sexual and urinary function, anxiety, depression, and overall QOL assessed at all timepoints.

研究组 & 干预措施
Arm A: Reference Group
Arm A will receive print educational materials about the benefits of exercise and diet for men with prostate cancer, with recommendations geared at men living with prostate cancer, mailed around the date of surgery. They also receive a 10-week text messaging program focused on recovery after radical prostatectomy surgery.
干预措施: Exercise and Diet (Behavioral)
Arm B (Arm A + Exercise)
Arm B receives the following: Arm A material plus access to an online portal with additional educational materials to help improve exercise habits and various tools, such as the ability to track exercise; additional educational print materials on exercise; additional text messages over 2 years that supports healthy exercise habits; and a 1-hour phone session at the start of the study followed by eight 30-minute quarterly phone sessions with an exercise coach over 2 years.
干预措施: Exercise and Diet (Behavioral)
Arm C (Arm A + Diet)
Arm C receives the following: Arm A material plus access to an online portal with additional educational materials to help improve diet habits and various tools, such as the ability to track diet; additional educational print materials on diet; additional text messages over 2 years that supports healthy diet habits; and a 1-hour phone session at the start of the study followed by eight 30-minute quarterly phone sessions with a diet coach over 2 years.
干预措施: Exercise and Diet (Behavioral)
Arm D (Arm A + Exercise + Diet)
Arm D receives the following: Arm A material plus access to an online portal with additional educational materials to help improve exercise and diet habits and various tools, such as the ability to track exercise and diet; additional educational print materials on exercise and diet; additional text messages over 2 years that supports healthy exercise and diet habits; a 1-hour phone session at the start of the study followed by eight 30-minute quarterly phone sessions with an exercise coach over 2 years; and a 1-hour phone session at the start of the study followed by eight 30-minute quarterly phone sessions with a diet coach over 2 years.

结局指标
主要结局
Median Time to prostate-specific antigen recurrence
时间窗: Up to 5 years post-surgery
The median time in months to PSA recurrence after surgery will be evaluated using prespecified biochemical recurrence (2x PSA ≥ 0.2) and detectable (2x PSA ≥ 0.03) PSA thresholds, at the time of analysis. A log-rank test to evaluate the time to recurrence among groups and multivariate Cox proportional hazards regression will be used to obtain a hazard ratio for the time to recurrence.
次要结局
- Proportion of participants with PSA recurrence over time(Up to 24 months post-surgery)
- Mean scores on the Expanded Prostate Cancer Index Composite Short Form (EPIC-26) over time.(Baseline, and 6 months, 12 months, and 24 months post-surgery)
- Mean scores on the urinary function domain of the EPIC-26 over time.(Baseline, and 6 months, 12 months, and 24 months post-surgery)
- Mean scores on the general anxiety scale of the Patient-Reported Outcomes Measurement Information System (PROMIS) over time.(Baseline, and 6 months, 12 months, and 24 months post-surgery)
- Mean scores on the Memorial Anxiety Scale for Prostate Cancer (MAX-PC) over time.(Baseline, and 6 months, 12 months, and 24 months post-surgery)
- Mean scores on the general depression scale of the Patient-Reported Outcomes Measurement Information System (PROMIS) over time.(Baseline, and 6 months, 12 months, and 24 months post-surgery)
- Mean scores on the 12-Item Short Form Health Survey (SF-12) over time.(Baseline, and 6 months, 12 months, and 24 months post-surgery)
