Hi Ellen. My husband was on CCNU and when that stopped working, the NO put him on Avastin. He has had 7 infusions so far and it seems to be doing the trick, an MRI scheduled for April 5th will give us the results, but no real side affects so far.
We are in Canada, and Avastin is generally prescribed when new growth appears and CCNU stops working, so we are taking this as a good sign.
Good luck, keep us posted!
