From the Guidelines
If a patient has a high Prostate-Specific Antigen (PSA) level, the next steps typically involve further evaluation to determine the cause, starting with a repeat PSA test to confirm the elevated level, as recommended by the American College of Physicians 1. The physician will likely recommend this repeat test to account for fluctuations in PSA levels due to various factors such as infection, recent ejaculation, or prostate manipulation. If the PSA remains elevated, a digital rectal examination (DRE) should be performed to check for prostate abnormalities. Additional tests may include a free PSA test, which measures the ratio of free to total PSA and can help distinguish between benign conditions and cancer. Imaging studies such as transrectal ultrasound or multiparametric MRI of the prostate may be ordered to visualize the prostate gland. If cancer remains a concern, a prostate biopsy is typically recommended, which involves taking multiple tissue samples from the prostate for microscopic examination, as supported by the guidance statement from the Clinical Guidelines Committee of the American College of Physicians 1. The biopsy is usually performed under ultrasound guidance and may require antibiotic prophylaxis. It's crucial to understand that an elevated PSA doesn't necessarily indicate cancer, as conditions like benign prostatic hyperplasia (BPH), prostatitis, or urinary tract infections can also cause PSA elevation. The decision to proceed with each step should be individualized based on the patient's age, overall health, PSA level, rate of PSA change over time, and personal preferences regarding potential treatment if cancer is found, considering the potential benefits and harms of screening as outlined in the guidance statement 1. Key considerations include the patient's risk factors for prostate cancer, such as African American race and a first-degree relative diagnosed with prostate cancer, especially before age 65 years, as well as the potential for overdiagnosis and overtreatment, highlighting the importance of shared decision-making in the screening process 1.

Next Steps for High PSA Levels
If a patient has a high Prostate-Specific Antigen (PSA) level, the next steps may involve further testing and evaluation to determine the cause of the elevated PSA. Some possible next steps include:
- Repeating the PSA test to confirm the results 2
- Performing a digital rectal examination (DRE) to check for any abnormalities in the prostate gland 3
- Conducting imaging tests such as transrectal ultrasonography (TRUS) or magnetic resonance imaging (MRI) to visualize the prostate gland and check for any abnormalities 4, 5
- Performing a biopsy to collect tissue samples from the prostate gland for further examination 2, 3, 5
Factors to Consider
When evaluating a patient with a high PSA level, several factors should be considered, including:
- The patient's age and medical history 4, 6
- The presence of any symptoms such as urinary frequency, urgency, or pain 2
- The results of any previous PSA tests or biopsies 2, 3
- The patient's family history of prostate cancer 4
Treatment Options
If a patient is diagnosed with prostate cancer, treatment options may include:
- Active surveillance, which involves monitoring the patient's condition with regular PSA tests and biopsies 5
- Radiation therapy, which uses high-energy rays to kill cancer cells 6
- Surgery, which involves removing the prostate gland and surrounding tissue 5
- Hormone therapy, which involves using medications to block the production of male hormones that can fuel cancer growth 6
