5 year old daughter diagnosed with Retinoblastoma and will be having treatment soon. Has anyone else been through this with their children?

My daughter 5 years old diagnosed with Retinoblastoma. She is going to have Enucleation soon and chemo. 

Any of you did it recently and how did that child cope up ? 

What are the side effects faced through Chemo ? 

How long after Enucleation started with chemo 

I know consultant will discuss. Would like to know practical journey.
