Poor kiddo. I'll keep him in my thoughts. Someone I know has a kid who has been fighting brain cancer for 4 years. They founded a nonprofit called The Max Love Project. They have lots of resources for families dealing with childhood cancer, with a focus on anti-cancer nutrition: maxloveproject.org. Pass along the link if you think it will help!
So sorry to hear about your friends' family. I'm glad the surgery was mostly successful. Localize chemo will be much easier on his little body. Poor thing. I hope that family gets lots of good news very soon. Is he at TCH?
