Scientists at The Institute of Cancer Research, London, have figured out a way to predict how long prostate cancer patients will benefit from the drug olaparib using a simple blood test. It turns out cancer cells are quite sneaky and can develop resistance to olaparib, even bringing back genes they were missing before!
The good news is that knowing this will help doctors personalize treatment and potentially develop new drugs to outsmart these crafty cancer cells. (I wanted to say bastard but my wife said crafty is more appropriate!)
