Count me in too, as someone who would be interested in knowing more about this. My mother ended all treatments in June 07 after MRI's through an 8-month course of radiation and chemo indicated first that the tumor was back, then growing. When she stopped, she dragged one foot, was falling frequently, and could not process routine tasks such as brushing her teeth and making coffee. She asked for a referral to Hospice too. Now I wonder at what point they are going to say their involvement was premature and wish us well. (Their support has been a Godsend! Visiting nurse, medications delivered to the door, respite care.) Mom is now more like her old self... sense of humor is showing some signs of returning, more conversation, more optimistic. She still needs daily oversight, but is really doing much more on her own... can make a salad, loads/unloads the dishwasher, even a little better gait and infrequent falls.
I had been posting on the Brainhospice site and asked the host there if she'd ever known anyone to make gains after showing symptoms from the end stages timeline and she said she had not, so I thought my Mom's case was pretty unique. Glad to know there are more of you out there experiencing a period of stability, and even gains!
