Scientists at the University of Surrey in the UK conducted a study for the detection of prostate cancer in men, drifting away from the analysis of prostate specific antigen (PSA) in the blood, and instead looking at the level of engrailed-2 (EN2) protein in a person’s urine.
The current testing method based on the PSA level in a person’s blood is known to cause false negatives, since higher levels of PSA can be found in men who have an enlarged prostate but no cancer, an article in nhs.uk notes.
The recent study analyzed the EN2 protein in the urine of 288 men, 82 of them confirmed via biopsy to have the disease and 102 of them cancer-free. Results from the new test correctly identified 66% of the men with cancer and 90% of the men without (http://www.nhs.uk/news/2011/03March/Pages/new-prostate-cancer-test-studied.aspx).
If this new test is released, it will spare men from having to receive unnecessary biopsies and can easily and quickly detect the disease.
Although the study still has a long way to go (further tests with larger groups are necessary to confirm the results), Road Scholar Transport will not stop spreading awareness on the road until a cure is found.
