Men with very high prostate-specific antigen (PSA) levels at safety-net hospitals are often African American with advanced prostate cancer. Targeted PSA screening could help identify more at-risk individuals for earlier intervention.
Area of Science:
- Urology
- Oncology
- Public Health
Background:
- Prostate-specific antigen (PSA) screening is crucial for early prostate cancer detection.
- Safety-net hospitals serve vulnerable populations who may have unique health challenges.
- Elevated PSA levels (≥100 ng/mL) warrant thorough investigation for advanced prostate cancer.
Purpose of the Study:
- To characterize men presenting with high PSA levels (≥100 ng/mL) at a tertiary care safety-net hospital.
- To identify a potential population for targeted PSA screening initiatives.
Main Methods:
- Retrospective review of 100 patients with initial PSA ≥100 ng/mL from 2004-2011.
- Data collected on demographics, disease characteristics, and survival from hospital records.
- Analysis excluded data from incomplete paper charts.
Main Results:
- 65 patients newly diagnosed with prostate cancer; 35 previously diagnosed.
- Median PSA 405.5 ng/mL; 81% had metastatic disease; 94% had Gleason ≥7.
- 89% were African American; many had lower socioeconomic status (homeless, uninsured).
- Newly diagnosed patients showed low rates of prior screening (23%) or biopsy (9%).
Conclusions:
- Men with PSA ≥100 ng/mL at safety-net hospitals are predominantly African American with advanced disease.
- Lack of screening may lead to late diagnosis and poor outcomes in at-risk populations.
- Targeted PSA screening strategies should be considered for vulnerable, high-risk patient groups.

Antigen Presenting Cells
T cells require the help of antigen-presenting cells (APCs), which process foreign antigens into smaller fragments that can be recognized by T cells. These APCs are highly specialized cells that efficiently internalize antigens...
