Study identifies new prostate cancer indicator
Scientists have identified a genetic fault that seems to be specific to fast-growing prostate cancer, paving the way for a new screening method to detect the disease.
The research, published in the journal Clinical Cancer Research, found that prostate cancers made up of cells containing an extra-large copy of chromosome eight were more likely to be aggressive.
The current prostate-specific antigen (PSA) test for prostate cancer has greatly improved detection rates, but is unable to discriminate between slow-growing cancers that need minimal treatment, and faster growing cancers that may require surgery.
The researchers said that testing for this genetic fault in men who had high PSA levels could greatly improve diagnoses and spare some patients the distress of unnecessary surgery.
The study was conducted by researchers based in the University of Porto, Portugal, and the University of Oslo, Norway and is published in the journal Clinical Cancer Research.
