Primary Outcome Measures:
  • Progression defined by PSA doubling time (PSADT) < 3 years, PSA > 10 at any time, or Gleason sum on repeat biopsy ≥ 7 (for men < 70 years) or ≥ 4+3 = 7 (for men ≥ 70 year) [ Time Frame: Up to 2 years ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Progression defined by PSADT and time to progression [ Time Frame: Up to 2 years ] [ Designated as safety issue: No ]
  • Time to treatment [ Time Frame: Up to 2 years ] [ Designated as safety issue: No ]
  • Comparison of quality of life (anxiety and depression, prostate cancer symptom checklist) between the two arms [ Time Frame: Up to 2 years ] [ Designated as safety issue: No ]
  • Diet as evaluated by three separate 24-hour dietary recalls at baseline and at 12 and 24 months [ Time Frame: Up to 2 years ] [ Designated as safety issue: No ]

Estimated Enrollment: 464
Study Start Date: January 2011
Estimated Primary Completion Date: June 2017 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Arm I
Patients receive the MEAL program intervention with dietary education and telephone counseling sessions of 24 months; the "Participant Notebook", which provides written material describing the counseling program, dietary targets, offers supporting information on strategies to achieve these targets, supplies referent tools to help patients accurately estimate servings of target foods, and recipes and articles about diet and prostate cancer. Patients also receive 8 regularly scheduled newsletters over the course of 24 months. The newsletters focus on study goals and progress and provide tips on achieving and maintaining diet change and include information on diet and cancer, the challenges of diet change, the advances in prostate cancer control, and new recipes.
Behavioral: telephone-based intervention
Patients undergo telephone counseling
Other: counseling intervention
Patients undergo telephone counseling
Other: educational intervention
Patients receive detailed or general newsletters
Procedure: therapeutic dietary intervention
Patients receive dietary education
Active Comparator: Arm II
Patients receive standard United States Department of Agriculture dietary guidelines for Americans. Patients also receive 8 regularly scheduled newsletters over the course of 24 months. The newsletters contain general information about diet and healthy lifestyle.
Other: educational intervention
Patients receive detailed or general newsletters

Detailed Description:

OBJECTIVES:

Primary

  • To determine if a telephone-based dietary intervention compared to no intervention will decrease clinical progression in AS patients.

Secondary

  • To compare the incidence of active treatment (surgery, irradiation, local ablation, or androgen deprivation) in AS patients receiving dietary intervention compared to no intervention.
  • To compare prostate cancer-related anxiety in AS patients receiving dietary intervention compared to no intervention.
  • To compare health-related quality of life in AS patients receiving dietary intervention compared to no intervention.

OUTLINE: This is a multicenter study. Patients are stratified according to age (≤ 70 years vs > 70 years), race (African American vs other), and time of baseline prostate biopsy (0-12 months before registration vs > 12-24 months before registration). Patients are randomized to 1 of 2 treatment arms.

  • Arm I: Patients receive the MEAL program intervention with dietary education and telephone counseling sessions for 24 months. Patients receive the "Participant Notebook", which provides written material describing the counseling program. It also outlines the dietary targets, offers supporting information on strategies to achieve these targets, supplies referent tools to help patients accurately estimate servings of target foods, and offers recipes and articles about diet and prostate cancer. The counseling sessions are divided into 4 phases, with the first three phases completed in 7 months and the fourth phase continuing for 17 months. The first phase comprises 6 counseling calls focusing on education and the rapid development of self-efficacy, the second phase comprises 4 calls over a 2-month period focusing on practical and consistent implementation of the dietary pattern, the third phase comprises 4 calls over a 4-month period helping patients habituate to the dietary pattern by providing regular performance reviews, and the fourth phase comprises 8 calls over a 17-month period and is a maintenance phase. Patients are encouraged to achieve 7 servings per day of vegetables (2 cruciferous, 2 tomato products, 3 other vegetables), 2 servings per day of whole grains, 1 serving per day of beans or other legumes, and 2 servings per day of fruit. Patients also receive 8 regularly scheduled newsletters over the course of 24 months. The newsletters focus on study goals and progress and provide tips on achieving and maintaining diet change. They also include information on diet and cancer, the challenges of diet change, the advances in prostate cancer control, and new recipes.
  • Arm II: Patients receive standard United States Department of Agriculture dietary guidelines for Americans. Patients also receive 8 regularly scheduled newsletters over the course of 24 months. The newsletters contain general information about diet and healthy lifestyle.

Blood (plasma and serum) and tissue samples are collected at baseline and at 12 and 24 months for biomarker and pharmacogenomic studies.

Patients complete quality-of-life assessments (Personal Habits Questionnaire, Functional Assessment of Cancer Therapy Scale-Prostate (FACT-P), Memorial Anxiety Scare for Prostate Cancer (Max-PC), International Prostate Symptom Score (IPSS), Expanded Prostate Cancer Index Composite 26 (EPIC-26), and Nutrition Self-Efficacy and Satisfaction with the MEAL Program) at baseline and at 6, 12, 18, and 24 months.

After study entry, patients are followed up every 3 months for 2 years.
