What Is the Longest Anyone Has Lived With a GBM Brain Tumor?
As of 2015, at least one person has lived 15 years after being diagnosed with a glioblastoma multiforme, an aggressive brain cancer, states Mayfield Clinic for Brain and Spine. Approximately 3 to 5 percent of glioblastoma patients survive long-term. Most patients typically die within one to two years after diagnosis.
The surviving patient, John, was 46 years old when he was diagnosed with glioblastoma multiforme and underwent surgery in January 1995. The surgeon removed about 90 percent of the tumor from the right frontal lobe, and then John received radiation treatments and chemotherapy, notes Mayfield Clinic for Brain and Spine. John had originally received a prognosis of three to six months to live, and his father had passed away six months after being diagnosed with the same type of tumor.
