Prostate cancer blood test could transform treatment, say scientists

Three-in-one test reveals which men with advanced cancer are suitable for treatment with 'precision' drug olaparib

Scientists have developed a simple three-in-one blood test they believe could transform treatment of advanced prostate cancer, helping to extend or save lives.

The test, developed by researchers at the Institute of Cancer Research (ICR) in London and the Royal Marsden NHS foundation trust, picks out men suitable for treatment with olaparib, part of a revolutionary class of drugs called "PARP-inhibitors", which stops damaged cells from repairing themselves.
