What causes a PSA bounce?
PSA bounce does not mean that the cancer has come back. It may be caused by the release of PSA from destroyed cancer cells or from normal prostate tissue exposed to the radiation treatment.
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.
Does external beam radiation shrink the prostate?
Radiation therapy can be an effective treatment for prostate cancer. It can shrink a tumor, relieve symptoms, and delay or halt the growth of cancer cells. A therapist may target a tumor with an intense beam of radiation from an external machine, or they may implant or inject radioactive materials into the body.
How common is PSA bounce?
In one study, approximately 12% of men who underwent treatment with external beam radiation therapy were reported to have a PSA bounce about nine months after treatment, on average.
How long can a PSA bounce last?
Results. Sixty-one patients (29.6%) experienced “PSA bounce”, at a median time of 16 months and lasted for 12 months.
What is a good PSA after brachytherapy?
Radiation therapy (external beam or brachytherapy) Ideally, post-treatment PSA levels should be less than 0.5 ng/ml, but this is rare; levels of 0.6–1.4 ng/ml may occur.
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.
What is a normal PSA after radiation?
What should PSA levels be 3 months after radiation?
Patients were characterized by 3-month post-RT PSA values: <0.10 ng/mL, 0.10 to 0.49 ng/mL, and ≥0.50 ng/mL. The researchers found that a higher 3-month PSA level was strongly associated with biochemical progression-free survival (bPFS), prostate cancer-specific survival (PCSS), and overall survival (OS).
