Medical Forum / Diseases and Disorders / Prostate Cancer / August 2004Good Bye PSA Tests ?
Looks like we now have a more reliable test then the old PSA test, click on the link below for the info. http://www.biotechfind.com/news/news-3611.htm Canada Bob. Hi Bob This is a strange new test. You have to have just had a prostate biopsy, and then given a urine sample to get prostate cells that have come loose and will be flushed out with the urine, in order to have this new test done on the urine. But, wouldn't the biopsy give an unequivocal answer if the biopsied area was sampled? and that IS a condition for the new test to work. It seems that if the sampled area, from which cells will be loosened, does not have cancer cells, then the cells in the urine will not show cancer. So, the area sampled must have cancer cells before the new test is positive. Am I correct?

Perhaps you saw something I didn't, but the report doesn't seem to say that the test only works on men who have had a biopsy. I would guess it would work simply by obtaining a urine sample and looking for the telltale marker. Note however that it probably won't mean the end of PSA testing because although it apparently catches the great majority of cancers, it does miss some. It also looks as if it might be expensive. I would guess it would be used after a PSA test suggested something suspicious and before a biopsy. In some cases, they might go ahead with the biopsy even if this test was negative. > Am I correct? > [quoted text clipped - 6 lines] >> >>Canada Bob. Hi Leonard You are indeed correct, and I was in error. The urine sample taking follows a DRE. Must be a vigorous one. Vernon > > Hi Bob > > [quoted text clipped - 29 lines] > >> > >>Canada Bob. |
