Summary
Prostate-specific antigen (PSA) is the most accurate tumor marker for diagnosing, staging, and monitoring prostate cancer. Elevated PSA levels can indicate disease progression after treatment, making it crucial for patient management.
Area of Science:
- Oncology
- Urology
- Biochemistry
Background:
- Prostate cancer is a significant health concern.
- Accurate diagnostic and monitoring tools are essential for effective management.
Purpose of the Study:
- To evaluate prostate-specific antigen (PSA) as the optimal analyte for diagnosing, staging, and monitoring prostate cancer.
- To review the applications of PSA in various treatment scenarios.
Main Methods:
- Literature review of PSA's role in prostate cancer.
- Analysis of PSA's utility in detection, staging, and post-treatment monitoring.
Main Results:
- PSA screening increases detection of localized prostate cancer.
- PSA levels >10 ng/mL correlate with higher rates of extracapsular disease.
- Elevated PSA indicates persistent disease post-treatment; PSA nadir is key in androgen deprivation therapy response.
Conclusions:
- Prostate-specific antigen (PSA) is the most accurate tumor marker in oncology.
- PSA effectively aids in the diagnosis, staging, and monitoring of prostate cancer.
