M.D. Anderson is the best cancer clinic, see also blog entry at the bottom of the following http://www.acscsn.org/Forum/Discussion/thread/view?msgid=73261&msgrid=1
Hi, sorry to hear about your brother's recent diagnosis. I am aware of excellent cancer center in Toronto, not sure where you live. Gamma Knife is the best method and the treatment may be combined with whole brain radiation. Have you met with neurosurgery (brain surgeon), please do this even if the case is not surgical at this time. I am sure you have met with a team of doctors that should include a neurologist, surgeon, oncologist and radiation doctors. These cases are usually discussed in a multidisciplinary tumor board. I would seek that type of second opinion out right away.
