Median follow-up after the end of radiotherapy was 108 months. A PSA bounce showed to be a significant factor for biochemical control (BC) and overall survival (OS) after ten years (BC10 of 83% with bounce vs. 34% without, p < 0.01; OS10 of 82% with bounce vs. 59% without bounce, p < 0.01).

What you should know about PSA levels after prostatectomy?
These factors include:
- age and life expectancy
- general health
- cancer grade and aggressiveness
- if cancer has spread and where
- previous treatments
Does an elevated PSA level mean I have prostate cancer?
Prostate-specific antigen (PSA) is a protein produced by prostate gland cells. Elevated levels may indicate prostate cancer, but PSA levels can also be affected by other things, such as enlarged prostate, a urinary tract infection, or recent ejaculation. On their own, PSA levels aren’t a good indicator of prostate health.
Does a high PSA mean I have prostate cancer?
The higher the PSA rises above 10 ng/mL, the greater the chance that you have prostate cancer. Your doctor may also monitor your PSA velocity, or doubling time, which means recording your baseline PSA the level at your very first PSA test and seeing how fast the PSA level increases over time. Rapid increases in PSA readings can suggest cancer.
How to understand PSA levels?
What is a correct PSA interpretation?
- a PSA value between 0–4 ng/mL can suggest that the cancer is confined in the prostate
- a PSA level between 4–10 ng/mL suggests that the cancer is 70% organ based
- a PSA level above 10 ng/mL suggests that the cancer is 50% organ based
What should PSA be after brachytherapy?
Recent studies have shown that for optimal results, PSA levels should be lower than 1 ng/ml, and even lower than 0.5 ng/ml. Levels that are above 1 or 2 ng/ml 12 to 18 months following completion of radiation treatments are very worrisome, because they indicate that the cancer may not have been eradicated.
Can prostate cancer come back after brachytherapy?
For example, a study of 1,449 men with prostate cancer treated with brachytherapy, published in the Journal of Urology, found that anywhere from 19% to 26% experienced biochemical recurrence within 12 years, depending on the definition of recurrence.
Can PSA rise after brachytherapy?
PSA can rise temporarily after brachytherapy. This is called PSA bounce. The level then lowers slowly. Usually a level of 2 ng/ml above the lowest point after treatment (the nadir) is taken as a sign of recurrence.
What is percent of prostate cancer returns after radiation?
Depending on the disease characteristics, 15-70% of prostate cancer patients recur after definitive radiation therapy, thus these figures suggest that over 100,000 men may present with recurrent disease after upfront radiation therapy.
What is the life expectancy after brachytherapy?
Relative survival rates 73% at 5 years after plaque brachytherapy, 55% at 10 years, 43% at 15 years, 31% at 20 years, 23% at 25 years, 19% at 30 years, 16% at 35 years and 14% at 40 years.
How long can you live after brachytherapy?
The biochemical recurrence-free survival rate for low-, intermediate- and high-risk patients 3 to 7 years after brachytherapy ranged from 85%-96%, 74%-97% and 38%-82%, respectively.
What should PSA be 5 years after radiation?
Researchers concluded that when PSA levels remain low (less than 2 ng/mL) five years after external beam radiation therapy, the great majority of patients will be biochemically disease-free at 10 years.
What is the average PSA for a 70 year old?
3.5-4.5: Normal for a man 60-70 yrs. 4.5-5.5: Normal for a man 70-80 yrs.
What is a normal PSA level for a 60 year old?
Decoding a PSA Test The median PSA for this age range is 0.6 to 0.7 ng/ml. For men in their 60s: A PSA score greater than 4.0 ng/ml is considered abnormal. The normal range is between 1.0 and 1.5 ng/ml. An abnormal rise: A PSA score may also be considered abnormal if it rises a certain amount in a single year.
What are the signs of prostate cancer returning?
The first involves the development of symptoms of recurrence such as leg edema, blood in the urine, progressive fatigue, bone pain and back pain. The second is referred to as a biochemical recurrence, and it involves a rise in the man's PSA (prostate-specific antigen) levels.
How effective is brachytherapy for prostate cancer?
Brachytherapy increases the 9-year success rate from 62 percent to 83 percent for those with intermediate to high-risk cancer. The overall outlook for people with prostate cancer, regardless of treatment plan, is excellent.
When does prostate cancer most likely recur?
Recurrence. Even if your cancer was treated with an initial primary therapy (surgery or radiation), there is always a possibility that the cancer will reoccur. About 20 percent to-30 percent of men will relapse (have the cancer detected by a PSA blood test) after the five-year mark, following the initial therapy.
How long does it take for a prostate to be undetectable?
Each type of treatment has an effect on PSA: Radical prostatectomy (surgical removal of the prostate) makes PSA undetectable in 6 weeks, because all prostate cells including PCa cells have been taken out of the body.
How long does it take for PSA to drop after radiation?
Radiation, whether beam radiation or brachytherapy (seed implants), causes a lowering of PSA about 12-14 months later. This is because radiation gradually exerts damaging “pressure” on PCa DNA so cells begin to die off. Also, they are unable to reproduce themselves.
How long does it take for a PCA to lower?
Focal PCa ablation will lower the PSA in 6 weeks because the tumor is destroyed. However, with healthy prostate tissue left in place it is expected that future blood tests will reflect the presence of low PSA levels due the activity of the normal cells.
How low is PSA after radiation?
It could go as low as zero (undetectable) but more often the value will range from a fraction above zero to 2 ng/ml. Once the PSA reaches nadir, it should remain stable for the rest of the patient’s life.
What is a PSA ball?
Brachytherapy: Follow the Bouncing (PSA) Ball? Prostate specific antigen (PSA) is like an ID tag for prostate cells. Each prostate cell, whether normal or cancerous, carries proteins (antigens) that can be “shed” into the bloodstream when some type of activity stimulates the prostate. Generally, the more constant the activity, ...
How long does it take for a T cell to show up in brachytherapy?
This is why it takes 1-2 years for the bounce to show up.
Is a bounce bad for cancer?
A bounce is not automatically bad. In fact, patients who have post-radiation bounce “… have improved PSA recurrence-free survival, distant metastasis-free survival, overall survival, and cancer-specific survival outcomes.”. [i] Yet no one knew exactly what causes a bounce, or how to explain how better survival is connected.
