Researchers at The Royal Marsden and The Institute of Cancer Research have developed a saliva test that could be a better way to identify men at high risk of prostate cancer than the prostate-specific antigen (PSA) test.
Findings from the BARCODE 1 study, presented at ASCO 2024, calculated the prostate cancer polygenic risk score (PRS) of patients recruited. Of these, 40% of the men with a high PRS score were diagnosed with prostate cancer, a significant increase from those identified by the PSA test. The new test also detected that 55% of the cancers in the study were aggressive, improving on the 36% in detected by the PSA test.
The PRSs were based on 130 genetic variations shown to be linked with prostate cancer. |
