“John has surpassed expectations for his survival,” the statement reads. “But the progress of disease and the inexorable advance of age render their verdict.

“Our family is immensely grateful for the support and kindness of all his caregivers over the last year, and for the outpouring of concern and affection from John’s many friends and associates, and the many thousands of people who are keeping him in their prayers.”

Glioblastoma – also known as glioblastoma multiforme (GBM), is the most aggressive cancer that begins within the brain.
