A 2006 study found that men who had a PSA velocity >0.35 ng/mL per year had a higher relative risk of dying from prostate cancer than men who had a PSA velocity http://www.selleck.cn/products/lee011.html a man has. With benign prostate conditions (such as benign prostatic hyperplasia), there is more free PSA, whereas cancer produces more of the attached form. Researchers are looking at other ways to measure PSA and use these measurements to determine whether cancer is present. Alteration of PSA cutoff level: A number of studies have used cutoff levels of 2.5 http://www.selleckchem.com/products/epacadostat-incb024360.html or 3.0 ng/mL, rather than the current cutoff of 4.0 ng/mL. In such studies, PSA measurements higher than 2.5 or 3.0 ng/mL are considered elevated. Researchers hope that using these lower cutoff levels will increase the chance of detecting prostate cancer; however, this method also may increase overdiagnosis and false-positive test results Other Detection Methods These can be used alone or together with a PSA test and digital rectal exam. MicroRNA patterns: Researchers have found that the pattern of microRNAs in a cell can differ between healthy cells and cancer cells. Some research also suggests that the microRNA patterns in early-stage prostate cancer and late-stage prostate http://www.selleckchem.com/products/i-bet-762.html cancer may be different. Nonmutation gene alterations: Research has already shown that certain genes become hypermethylated and inactivated during the development and progression of prostate cancer. Scientists hope to identify DNA methylation changes and protein modifications that could identify prostate cancer early and help predict tumor behavior. Gene fusions: The gene fusions found in prostate cancer involve members of the ETS family of oncogenes. Researchers are investigating whether diagnostic or prognostic tests based on gene fusions can be developed. PCA3: Also known as DD3, PCA3 is a prostate-specific RNA that is reported to be expressed at high levels in prostate tumor cells. A urine test for this RNA, to be used in addition to current prostate cancer screening tests, is currently under study. Differential detection of metabolites: Molecules produced by the body's metabolic processes, or metabolites, may be able to help distinguish between benign prostate tissue, localized prostate cancer, and metastatic prostate cancer. One such molecule, known as sarcosine, may be associated with prostate cancer's invasiveness and aggressiveness. Investigators are determining whether they can develop a test based on sarcosine.
