Wrong.
There is no such thing such as chemotherapy because of the blood/brain barrier, so forget that.
Wrong.
What treatment he has received is to give him possibly six months to a year at the most from diagnosis.
The primary treatment is to "de-bulk" the tumor to reduce the volume that it imposes on the brain that sits in a fixed volume chamber. About half GBM patients have a second de-bulking surgery to extend survival another 5-6 months. The standard chemo used (BCNU) crosses the blood brain barrier but the glioma is a tough customer. Nevertheless good studies have demonstrated efficacy. Radiation of the site also is proven to extend survival.
Success, however, means extending life by months. Its all about quality of life - if the brain manages to restructure key functions to healthy brain tissue patients can retain pretty good function and those extra months can be priceless.
Thanks for bringing up these incorrect points so reality can be presented.
Thanks Doc. I did sleep at a Holiday Inn however, plus I lost two family members and one dear friend from GLIOBLASTOMA. My niece, was under the care of Dr. Keith Black of Cedar-Sinai, premier world class neurosurgeon. Our family spent much time with Dr. Black discussing treatment, time left, exactly what Glioblastoma is......so sorry I offended you and glad I did.
