Radiation Therapy! Again, for I know. Ready to share new things that are useful. You and your friends. AdvertisementsProstate definite antigen (Psa) is a protein produced by the prostate gland. It is measured in the blood stream and is a useful tool for following men who have been treated for prostate cancer. Does a Psa elevation after radiation treatment, be it a prostate seed implant and/or external beam radiation therapy, all the time signify disease recurrence?
What I said. It is not outcome that the true about Radiation Therapy. You read this article for information about what you wish to know is Radiation Therapy.How is Psa Bounce After Radiation Therapy For Prostate Cancer: keeping An Eye On The Ball
We had a good read. For the benefit of yourself. Be sure to read to the end. I want you to get good knowledge from Radiation Therapy.In the past, a Psa elevation after a prostate seed implant or external beam radiation therapy was considered to be a harbinger of a prostate cancer relapse, often prompting costly tests and invoking a great deal of patient anxiety. Then, when the Psa level climbed to10 ng/ml or greater, men were settled on hormonal therapy. Since the latter is connected with a amount of unpleasant side effects, it is desirable to refrain from using hormonal therapy unless necessary. The question then arises: when does an increase in the Psa level not signify that cancer has returned?
There is a phenomenon known as a Psa bounce, in which the Psa level jumps up within one to three years after the man has completed radiation therapy. The Psa level ultimately returns to the baseline it attained just after treatment. Psa bounce may be caused by death of the damaged cancer cells that publish their Psa.
A Psa bounce regularly begins with less than a one-point (less than 1 ng/ml) rise in the Psa level. Also, elevations of the Psa level after three years are less likely to be part of a bounce, and unlike a bounce, rises of the Psa level by more than 1.2ng/ml are less likely to drop back to their starting points.
A up-to-date study collected data on 7,500 men who were treated for prostate cancer with radiation therapy. Nearly half of these men were found to have a Psa bounce. However, there was no adverse corollary on their survival. In fact, these men fared just as well as men whose Psa did not bounce. Also, patients who show such a Psa bounce less than two years after medicine may be less likely to have cancer return later.
More good news is now that physicians are aware that an elevation in the Psa level does not necessarily mean prostate cancer has recurred, men whose Psa bounces after radiation therapy can be followed by their doctors, who can repeat the Psa blood test six months later.
