A subsequent increase in PSA levels by 2.0 ng/mL [disputed – discuss] above the nadir is the currently accepted definition of prostate cancer recurrence after radiation therapy. [citation needed] Recurrent prostate cancer detected by a rise in PSA levels after curative treatment is referred to as a "biochemical recurrence". The likelihood of ...
After surgery or radiation therapy, PSA may start to rise again, which is called biochemical recurrence if a certain threshold is met in PSA levels (typically 0.1 or 0.2 ng/ml for surgery). At 10 years of follow-up after surgery, there is an overall risk of biochemical recurrence of 30–50%, depending on the initial risk state, and salvage ...
After either treatment, PSA levels are monitored regularly. Up to half of those treated will eventually have a rise in PSA levels, suggesting the tumor or small metastases are growing again. [53] People with high or rising PSA levels are often offered another round of radiation therapy directed at the former tumor site.
By the age of 50, men should be having prostate-specific antigen, or PSA, testing done annually. - SDI Productions/E+/Getty Images
Men without prostate cancer typically have PSA levels of under 4 nanograms per milliliter (ng/mL), according to the American Cancer Society. PSA levels between 4 and 10 suggest you could have ...
The 4Kscore combines total, free and intact PSA together with human kallikrein 2. [46] It is used to try to determine the risk of a Gleason score greater than 6. [46] The Prostate Health Index (PHI) is a PSA-based blood test for early prostate cancer screening. It may be used to determine when a biopsy is needed.
Prostate cancer staging. Prostate cancer staging is the process by which physicians categorize the risk of cancer having spread beyond the prostate, or equivalently, the probability of being cured with local therapies such as surgery or radiation. Once patients are placed in prognostic categories, this information can contribute to the ...
Active surveillance is a management option for localized prostate cancer that can be offered to appropriate patients who would also be candidates for aggressive local therapies (surgery and radiotherapy), with the intent to intervene if the disease progresses. Active surveillance should not be confused with watchful waiting, another ...
