Social, Structural, and Lifestyle Drivers of Prostate Cancer Disparities

July 1, 2026 updated by: University of California, San Francisco

Prostate Cancer (PC) is the most common non-cutaneous malignancy diagnosed and second leading cause of cancer death among men across the United States. PC among Black men accounts for a higher proportion alike of cancer diagnoses and deaths. In the prostate specific antigen (PSA)-based screening era, mortality rates improved at a similar velocity among Black and White men, but the 2- to 3-fold excess mortality burden borne by Black men has persisted over the past 40 years, the second highest among all major cancers. In recent years mortality is rising among Black men, and at a rapid velocity.

The explanations for this disparity-the extent to which it is attributable to genetics, environmental factors including Structural and Social Determinants of Health (SSDH), or access to care-are multifactorial and have been elucidated to a limited extent. A large meta-analysis recently found that across dozens of studies and cohorts, greater adjustment for clinical and SSDH factors generally resulted in race itself dropping as a significant predictor.

These and other findings suggest that the determinants of disparity be identified at time of, and prior to, cancer diagnosis, and that both genetic and environmental factors contribute to earlier development and progression.

Detailed Description

The investigators hypothesize that SSDH factors drive cancer development differentially by race, and including SSDH factors in prediction models can improve risk prediction to guide decision-making regarding screening, diagnosis, and treatment across race and ethnic groups.

PRIMARY OBJECTIVE:

To identify not yet discovered SSDH and lifestyle factors that associate with identification of unfavorable vs. favorable prostate cancer histology between Black, Hispanic, and Asian men.

OUTLINE:

UCSF participants who agreed to participate in the Urology 90991 Biobank Consent (UCSF internal review board (IRB) #11-05226), and urology surgeons at community hospitals may refer participants for radical prostatectomy to University of California, San Francisco. Potential participants will be approached by the UCSF study team for an offer to participate and Non-UCSF participants will be asked to sign a medical release form prior to the research team collecting data from your medical record about your prostate cancer and treatment.

Design Details

Cohorts and Interventions

Group / Cohort
Intervention / Treatment
Men with prostate cancer
Participants who have planned or completed a non-investigational radical prostatectomy will be asked to complete a series of questionnaires online covering a subset of community-informed SSDH measures and individual exposures. Responses will be recorded in a secured database. . It will take about up to 2 hours to complete the surveys. There will be questions about your demographics (education level, income, employment, etc.); health care access and quality; lifestyle and behaviors. Data from your medical record about your prostate cancer and treatment will also be collected.
Other: Questionnaires
Participants will receive surveys to complete online via a secure system.
Other Names:
  • Surveys
Other: Medical Record Review
Data will be collected from participants medical charts which includes disease history, pathological findings, and other disease characteristics.
Other Names:
  • Medical Chart Review
