A further study, the NHS Comparison Arm for ProtecT (CAP), as part of the Prostate testing for cancer and Treatment (ProtecT) study, randomized GP practices with 460,000 men aged 50–69 at centers in 9 cities in Britain from 2001–2005 to usual care or prostate cancer screening with PSA (biopsy if PSA ≥ 3). [65]
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.
Prostate cancer is the uncontrolled growth of cells in the prostate, a gland in the male reproductive system below the bladder.Abnormal growth of the prostate tissue is usually detected through screening tests, typically blood tests that check for prostate-specific antigen (PSA) levels.
Asymptomatic inflammatory prostatitis is a painless inflammation of the prostate gland where there is no evidence of infection. [1] It should be distinguished from the other categories of prostatitis characterised by either pelvic pain or evidence of infection, such as chronic bacterial prostatitis, acute bacterial prostatitis and chronic pelvic pain syndrome (CPPS). [2]
The reduction in testosterone levels that occurs during GnRH antagonist therapy subsequently reduces the size of the prostate cancer. This in turn results in a reduction in prostate-specific antigen (PSA) levels in the patient's blood and so measuring PSA levels is a way to monitor how patients with prostate cancer are responding to treatment ...
The drug is one of only two treatments that help to promote bone formation, and the first to reduce bone loss at the same time.
GnRH agonists eventually cause the same side effects as orchiectomy but may cause worse symptoms at the beginning of treatment. When GnRH agonists are first used, testosterone surges can lead to increased bone pain from metastatic cancer, so antiandrogens or abarelix is often added to blunt these side effects.
IH can predispose individuals to osteopenia or osteoporosis, [2] and affects the entire body. IH arises due to faulty calcium homeostasis , a closely monitored process, where slight deviations in calcium transport in the intestines, blood, and bone can lead to excessive calcium excretion, bone mineral density loss, or kidney stone formation.
