In general, the most common form of glioblastoma arises from star-shaped cells called astrocytes in the nervous system, according to the American Brain Tumor Association. It's hoped Downie's case will create an opportunity for awareness and fundraising for all glioblastoma patients, Perry said. Cook said in an interview with CBC News Network. "Gord does have one positive factor, which is the 1p/19q deletion, which will improve his response to chemotherapy," Dr. Cook called the biomarker the 1p/19q deletion. Gord Downie's 'incurable' brain cancer won't keep him from singing, his doctor saysīiomarkers on the tumour showed it was amenable to treatment, he said, and Downie has since responded favourably.
Douglas Cook, of Kingston General Hospital, was able to largely remove it, said Sunnybrook neuro-oncologist Dr. Glioblastoma is described as the most common and aggressive tumour that starts in the brain, Sunnybrook Health Sciences Centre in Toronto says.Īt a news conference on Tuesday, the hospital announced it is treating Tragically Hip singer Gord Downie for the terminal brain cancer.ĭownie's tumour was located in a sufficiently accessible part of the brain that Dr.
