Understanding of Genetics by Men at Risk for Prostate Cancer

November 4, 2025 updated by: Ewan Cobran, Ph.D., Mayo Clinic
With this greater certainty regarding prognosis, men with localized prostate cancer are now equipped with make better treatment planning decisions. This study is designed to investigate the understanding of prognostic genetic technology in African American and rural White men at risk for localized prostate cancer.

Study Overview

Status

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Novel genomic technology, such as microarray analyses and next-generation sequencing, have improved the understanding of prostate cancer biology and prognosis. The National Comprehensive Cancer Network (NCCN), in 2016, recommended that patients and clinicians consider tissue-based genetic tests for localized prostate cancer. However, while much enthusiasm currently exits for the rapidly increasing field of genomic medicine, the use of multi-gene mRNA expression panels raises the potential for further divergence in prostate cancer treatment outcomes by race and low socioeconomic status. We know that health disparities persist in low income groups despite the existence of evidence-based guidelines and that adoption of state-of-the-art methods often lag behind in these groups.

The goals of this study are to explore how men at risk for localized prostate cancer comprehend prognostic genetic technology, and examine how an educational video about genetics impacts patient-caregiver communication of prognostic genetic technology. The study rationale is that without direct attention to genomic comprehension, the enthusiasm that exists in the rapidly increasing field of prostate cancer genomic medicine may not translate into health benefits for men with localized prostate cancer. The central hypotheses are men with lower levels of education will demonstrate a severe lack of genomic comprehension of tissue-based genetic tests for localized prostate cancer; and tailored prostate cancer education will significantly improve communication in a low literacy population.

The study approach is innovative because it applies a mixed-methods community-engagement research framework to explore how African American and rural White men at risk for localized prostate cancer, comprehend and interpret data generated from genetic technology. The proposed research is significant because of its potential to improve public health by improving the understanding of prognostic genetics in minority, low income, and rural populations, and engage and educate these diverse communities about genomics.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

40 years to 95 years (Adult, Older Adult)

Accepts Healthy Volunteers

Yes

Description

Inclusion Criteria:

  • African-American or White men
  • Living in a rural or urban areas
  • Age 40 to 95 years old
  • Able and willing to provide informed consent
  • English-speaking
  • Willing to participate in the study.

This study will use the United States Department of Agriculture Office of Rural Development's definition of rural, which is as a city or town that has a population less than 50,000 inhabitants to define rural.

This study will use the United States Census Bureau's definition of urban, which is a city or town that has a population greater than 50,000 inhabitants to define urban.

Exclusion Criteria:

Women will be excluded from participating in this study. However, women will be recruited to serve on an advisory panel to review the video-based educational tool for the comprehension of genomic terminology for prognostic genetic testing in patients with localized prostate cancer.
