Kennedy's best hope may lie in cancer vaccine trial

The general prognosis for anyone diagnosed with malignant glioma is poor. The most common form is glioblastoma multiforme, which swiftly dispatches cancer cells throughout the brain. Patients generally have up to three years to live following diagnosis. Given Senator Ted Kennedy's advanced age, his prognosis would appear to be particularly poor.

One of Senator Kennedy's best chances in defeating the malignant brain tumor that afflicts him could be an experimental vaccine, and reports are already circulating that he may be included in a trial that has extended the lives of some patients by three to six years. The vaccine is designed to attack cancer cells in the body after surgeons remove the brain tumor, preventing or slowing the return of the tumor.
