PSA Levels after Prostatectomy

The purpose of a prostatectomy is to remove all cancer or as much of it as possible. If your cancer hasn’t spread, this procedure might cure you. But no surgery is perfect. Prostate cancer can return after a prostatectomy. Although surgeons remove the prostate gland during a prostatectomy, some cancer cells can travel into the surrounding tissue. If these cancer cells multiply, they can cause prostate cancer to return. PSA or prostate-specific antigen is a protein produced by both normal and cancerous cells in the prostate. After a prostatectomy, PSA levels in your blood should fall to undetectable levels within six to eight weeks.

Why is PSA testing required after surgery?

A regular PSA test after a prostatectomy is a way for your doctor to keep track of your treatment. It can help your doctor see how well your surgery worked, and if your cancer has come back. While PSA is not always reliable when it comes to general cancer screening, it is an effective indicator of cancer recurrence. A high or rising PSA level could mean cancer cells are still circulating in your body. If you have had a prostatectomy, or your prostate gland surgically removed due to prostate cancer, prostate-specific antigen (PSA) testing is still essential.

How to Interpret PSA Test Results?

PSA tests can be challenging to interpret. Tests can also vary from laboratory to laboratory. To ensure accurate comparison, it’s essential to use the same lab each time you are tested. A more precise way to find out if you have cancer is to test how quickly PSA levels rise. If your PSA level is low and not rising after repeated tests, it is probably not a cancer recurrence. That is because other non-cancerous residual prostate cells in your body can produce small amounts of PSA. If the result is greater than or equal to 0.2 ng/mL and it’s risen on two separate tests taken at least two weeks apart, it is called a biochemical relapse. You still have PSA in your bloodstream. There is a chance that cancer has recurred. A PSA level higher than that may indicate a locally advanced tumor.

How PSA Levels Are Monitored After Prostatectomy

After prostatectomy, the assessment of PSA levels generally involves blood tests. Usually, PSA levels are checked every 3 to 6 months for the first 2 years, then annually thereafter. Regular monitoring of PSA levels allows the doctor to evaluate for signs of cancer recurrence.

PSA Level Ranges and What They Mean

Here is a rough division of PSA levels after prostatectomy:

• < 0.1 ng/mL: Considered an undetectable PSA level, which usually indicates that all prostate tissue and cancer have been removed as a result of surgery.
• 0.1 – 0.2 ng/mL: This level can be normal in some cases, but it does suggest that some tissue may remain. Continued monitoring is needed to determine whether PSA increases.
• > 0.2 ng/mL: This is the threshold that is commonly used to define biochemical recurrence. A PSA level greater than 0.2 ng/mL that subsequently rises indicates a resurgence of cancer.

What if PSA Levels Increase?

If PSA levels increase after prostatectomy, further work-up is needed. A provider may recommend additional imaging, such as bone scans, CT scans, or MRI, to assess whether the cancer has spread or recurred.

Treatment options for recurrence may differ, including:

• Salvage Radiation Therapy: If the cancer has recurred and is diagnosed early, radiation therapy to the prostate bed (the area where the prostate used to be) is often successful in killing remaining cancer cells.
• Hormone Therapy: If the cancer has spread or if radiation is not effective, hormone therapy is then used to lower testosterone levels that fuel cancer cell growth.
• Chemotherapy: If the cancer has spread to other parts of the body, it may be used.

Emotional and Psychological Impact of PSA Levels

Post-surgery can be an emotional time for the patient. The thought of increasing PSA levels can certainly be upsetting. It is essential to learn that prostate cancer can be effectively managed, even if it can recur. Talking to a provider, joining a group, or seeking counseling can help men deal with the anxiety that accompanies uncertainty about the meaning of PSA level changes.

High PSA Levels and Treatment:

You might not need treatment right away. If you have had multiple PSA tests and it appears that your PSA level is rising, several factors will influence the next steps. These factors include:

• age and life expectancy
• general health
• cancer grade and aggressiveness
• if cancer has spread, and where
• previous treatments

In some cases, high PSA levels in the blood are not due to cancer cells. Some factors that can affect PSA levels include old age, medication, and ethnicity. A doctor will take these factors and the person’s medical history into account when looking at test results. This can help them decide if PSA levels are high enough to cause concern.

Conclusion:

It is essential to get the PSA test every few months after your operation. Getting tested for cancer many times can cause a lot of anxiety, and unclear results can cause you to worry. A little knowledge can help calm your fears. Before you have this test, find out what to expect. Ask Dr. Razdan what your results might mean and what will happen if your PSA level is higher than it should be. Learning that your PSA level is higher than it should be can be very stressful. You may need more treatment, or you might be able to wait and have regular PSA tests to watch your cancer.

Frequently Asked Questions:

Question 1. If I have rising PSA levels after prostatectomy, what does it mean?

Answer. The rising PSA level after prostatectomy can indicate that prostate cancer has returned or some prostate tissue was left behind during surgery.

Question 2. What is the normal PSA level after prostatectomy?

Answer. A normal PSA level after prostatectomy is usually less than 0.1 ng/mL or should be undetectable. This normal PSA level indicates that all prostate tissue and cancerous cells have been removed.

Question 3. How soon after prostatectomy should PSA levels be checked?

Answer. Regardless of your doctor’s recommendations, typically PSA levels are checked every 3-6 months for the first two years after prostatectomy, and then annually after that.

Question 4. Can a rising PSA level always mean cancer recurrence?

Answer. A rising PSA level does not always mean cancer recurrence. A PSA level can rise for other reasons, and a PSA bounce can occur after radiation therapy, where PSA temporarily increases before dropping down.
