Daniel A. Nader: Well, it is possible, but usually the therapies for lung cancer include surgery, radiation therapy, and chemotherapy. And when a patient is first diagnosed with lung cancer, we do staging. This helps identify prognosis, and it helps identify what the treatment is going to be that the patient is going to receive. When a patient is put in remission, and remission means no evidence of active disease, the patient is followed very closely over a five year time period. It is at that point in time that we say that the cancer has been successfully managed.
