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 ...
Nowadays, PIN 1 is referred to as low grade PIN, and PIN 2 and PIN 3 are grouped together as high grade PIN. [10] Only high grade PIN has been shown to be a risk factor for prostate cancer. Because low grade PIN has no significance and does not require repeat biopsies or treatment, it is not mentioned in pathology reports.
Those with localized tumors and PSA between 10 and 20 ng/mL are designated stage II – subdivided into IIA for Gleason grade group 1, IIB for grade group 2, and IIC for grade group 3 or 4. Stage III is the designation for any of three higher risk factors: IIIA is for a PSA level about 20 ng/mL; IIIB is for T3 or T4 tumors; IIIC is for a ...
Biochemical recurrence is a rise in the blood level of prostate-specific antigen (PSA) in prostate cancer patients after treatment with surgery or radiation. Biochemical recurrence may occur in patients who do not have symptoms. It may mean that the cancer has come back. Also called PSA failure and biochemical relapse. [1]
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.

Serum PSA tests, routine imaging of the prostate, and tests for Chlamydia trachomatis and Ureaplasma provide no benefit for the patient. [ 35 ] Extraprostatic abdominal/pelvic tenderness is present in >50% of patients with chronic pelvic pain syndrome but only 7% of controls. [ 36 ]
