This is a great finding. I'm doing braincancer research myself and that's where my main concern comes from. By reading the abstract (on a train, no time for the full article yet) I understand they are using fineneedle aspiration to get their samples. That would work for most easy accessible tumors but for braintumor the human skull will be too big of a barrier. I'm still hoping for methods where samples from the peripheral blood will be used. Secondly I wonder what the costs willbe when antibodies for more than just one specific tumor will be used. Now they scan for one tumor by using 4 proteins. Scanning for more types of cancer will increase costs dramatically thought. Nevertheless great finding and hopefully available in clinics all over the world soon (but it usually takes an other 10 years).
