My husband had this tumor. He was initially told he had 6 mos. He decided to fight and found another surgeon to go in again. He had already had a course of radiation and chemo. The surgery was succesful in that they were able to remove more tumor than before and what they left behind had been killed by the radiation. He lived for 3 1/2 years after. The tumor never did regrow. He had complications with the shunt that was draining excess cerebralspinal fluid and ultimately passed from those complications.
