I truly feel for you and your friend. I'm going through this now. I'm about halfway through radiation and Temodar for apparent brain mets. It's terrifying but it's so much better now that ever before. Take a look at the following post. It gives new 3 year survival statistics as 63% with brain mets.

(get those brain MRIs: they said it again in the ASCO 2006 Highlights section.)
Best of everything,
