ABSTRACT: The introduction of prostate-specific antigen (PSA) as a reliable tumor marker for prostate cancer brought significant changes in the end points used for outcome reporting after therapy. With regard to a definition of failure after radiation, a consensus was reached in 1996 that took into account the particular issues of an intact prostate after therapy.
Treatment For Prostate Cancer | Radiation Therapy For Prostate Cancer About the Prostate. The prostate is a gland found in men that is part of the genitourinary system, a system which also includes the bladder, kidneys and testis. It is located in the pelvis, just below and behind the bladder, and just in …
1998 PMID 9510352– «The effect of ejaculation on prostate-specific antigen in a prostate cancer-screening population.» (Stenner J, Urology. 1998) Conclusion: For the total screened population, ejaculation has no clinically significant effect.
Radiation therapy, also called X-ray therapy, uses high levels of radiation to kill prostate cancer cells or keep them from growing and dividing, while minimizing damage to healthy cells.
Prostate cancer is often curable with surgery and radiation therapy. According to Cancer Research UK, about 1 in 3 men with early-stage prostate cancer have a recurrence after treatment. If it
Prostate cancer is often detected by a prostate-specific antigen (PSA) test, which subsequently leads to a biopsy. Prostate cancer is expected to affect over 164,000 men in the United States this year, According to the American Cancer Society .
Dec 18, 2013 · The widely used PSA (prostate-specific antigen) test measures a man’s PSA level and, when consistently elevated, can indicate prostate cancer. After a definitive diagnosis, many men elect robotic prostate surgery for complete removal of the cancerous prostate gland.
After radiation therapy by either method, there is still a prostate gland present, so there will still be normal prostate cells that are a source of some PSA. The PSA level falls more slowly, taking perhaps six months after brachytherapy and up to a year after EBRT to reach its lowest level, and it does not fall to undetectable levels.
Feb 16, 2016 · After radiation therapy. The different types of radiation therapy don’t kill all of the cells in the prostate gland, so they’re not expected to cause the PSA to drop to an undetectable level. The remaining normal prostate cells will still make some PSA. The pattern of the drop in PSA after radiation therapy is also different from after surgery.
