This is a major breakthrough in finding the best treatments for a patient. They use a new test which can predict if your tumor is going to respond to Temodar (and a handful of other drugs). The important point is that there are some patients with unmethylated MGMT that are predicted to respond to Temodar even though we thought these people had a very little chance of responding. And they did respond. There are also cases presented where patients with methylated MGMT were predicted that there tumor would not respond to Temodar and they did not respond.
