A more refined prognosis can be established by consideration of prostate-specific antigen, and grade (i.e. Gleason score in the Gleason grading system). For example, it is common to classify patients into high, intermediate and low-risk groups on the basis of these three factors (TNM stage, PSA and Gleason score).
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 ...
Over diagnosis is the detection of a cancer that would otherwise not have been diagnosed in the lifetime of the host if the detection test (e.g., PSA and/or prostate biopsy) had not been performed. Treatment of men who would otherwise not have known about their cancer in the absence of PSA testing and biopsy are over treated.
A meta-analysis of five randomized controlled trials concluded that PSA screening, at best, had a small effect on prostate-specific mortality–one death avoided for 1,000 men screened over 10 ...
The prognosis of diagnosed prostate cancer varies widely based on the cancer's grade and stage at the time of diagnosis; those with lower stage disease have vastly improved prognoses. Around 80% of prostate cancer diagnoses are in men whose cancer is still confined to the prostate.
However, the Gleason score is not simply the highest grade (least differentiated) pattern within the tumor. Rather, it is a combination of the most two most frequent patterns seen. This recognizes that prostatic carcinomas have multiple patterns and that prognosis is more accurately determined by adding the scores of the two most prevalent ...
Prostate-specific antigen (PSA), also known as gamma-seminoprotein or kallikrein-3 (KLK3), P-30 antigen, is a glycoprotein enzyme encoded in humans by the KLK3 gene.PSA is a member of the kallikrein-related peptidase family and is secreted by the epithelial cells of the prostate gland in men and the paraurethral glands in women.
