Otis Brawley, MD, chief of solid tumors at the Winship Cancer Institute of Emory University, called the test important and expected to be widely used.No one is completely satisfied with the current PSA test for prostate cancer. A man without prostate cancer can have elevated PSA levels. A man with advanced prostate cancer may have very low levels of PSA.
Getzenberg has a financial interest in the test. But experts who have agreed to win the race that has enormous potential.
Both in terms of diagnosis of cancer when he was done there , both in terms of not detecting cancer when he was not really there , the EPCA-2 test beat the PSA test.
Palapattu Ganesh, MD, assistant professor of urology at the University of Rochester, agrees that more studies should be done. But he tells WebMD that the test is an important step toward the Holy Grail of detection of prostate cancer:. Not so much identifying men with prostate cancer, but to identify men with prostate cancer who have aggressive disease
Charles A. Coltman Jr., MD, Associate Chairman of the fight against cancer and prevention in San Antonio Southwest Oncology Group, called the results surprising and remarkable , but warns that the test was tried on a few patients.
In a clinical trial designed by Merlin, in increments of whole blood were measured. The researchers compared the anterior surface of the fist on the surface of blood present and created a formula for the film of blood on hand. They determined that the hand covers an area of ??blood that equals about 20 ml.

I predict by next year, this test is widely used to find the guy who has prostate cancer, and if received radical prostatectomy, would relapse very quickly, Brawley tells WebMD. He will say to this man, Moving from an unnecessary surgery and get pelvic irradiation and hormone treatment now.
At least one third, perhaps two-thirds of children with localized disease of cancer that never leave the prostate and does not bother them, says Brawley. This new test does not help these kids who are treated for prostate cancer, but it should not. I hope that will help these men as soon as possible.
This not only if you have prostate cancer, but what kind of prostate cancer you have, said Ghezzi.
More importantly, he beat the PSA test to predict whether prostate cancer had already spread outside the prostate gland. When this happened, the standard treatment for prostate cancer - and brachytherapy - fail to heal.
The new test looks for a protein called EPCA-2-2 antigen or early cancer. Unlike the PSA protein on which the current PSA test, this protein was not found in normal prostate cells. Instead, the EPCA-2 occurs in relatively large amounts only in prostate cancer cells.
When - and if - the EPCA-2 test has been approved, people will always need more.
An experimental blood test seems to work better than the current PSA test - and can tell if the spreads.
Getzenberg says that there are at least two years before the test is the way with the approval of the FDA. All the experts who spoke to WebMD to establish that the test will be required before large scale is not clear how the test works.
