Glioblastoma has received much attention since recent high-profile cases like John McCain and Beau Biden. But University of Minnesota Medical School researchers have been working toward a treatment long before these cases.

Glioblastoma is a deadly form of brain cancer that kills more than 13,000 Americans annually. According to Dr. Clark Chen, Glioblastoma is known for how aggressively it can grow.

However, a promising new multi-step treatment is currently in phase lll of clinical trials. In total, the treatment consists of three steps and takes about six weeks to complete.

"The unique aspect of this treatment is we create chemotherapy in the brain," Dr. Chen told Kare 11 in an interview.

He believes they'll be able to gauge the effectiveness of this promising new treatment in the next year.
