Think of it as a protective gate.Dr. Boockvar says, 'we open the gate and we literally spray the chemotherapy agent onto the tumor."This is all part of the first phase of a clinical trial. So far only six patients have had this treatment. And doctors are still trying to make sure it's safe.They're already seeing a positive response in some patients.Dr. Boockvar says, "MRI has shown that the tumors are shrinking."There are risks including hemorrhage or seizure.Still Lois says it's worth it.Lois Cole says, 'I am hoping it will elongate my life and give me the opportunity to do more things that I would love to do."Doctors hope this will not only be a breakthrough for brain cancer, but for many neurological diseases.
