Hello, my sister was diagnosed with Glioblastroma high grade (4) last year. The operation was done for the removal and the. Radiotherapy and chemo has been going on for 7 months. We have done an MRI last week and found out that there is another occurrence of the same giloma in the brain. Chemotherapy hasn’t been effective. Someone has suggested immunotherapy however my sister is now in a very fragile state with considerably low platelets after chemo. Can someone advise what are the recovery success rates with treatments like immunotherapy or oncolytic virus therapy. Any suggestion or help would be greatly appreciated. Many thanks and kind regards, W
