Child cancer: tumor of Boland

Hello,
I'm writing from France, my daughter is 7 Months, the doctors discovered, when i was pregnant, a tumor on her right's kidney.
3 weeks after her birth, she was opered, ablation of kidney.
But there was a complication, the tumor has spread to the colôn, the surgeon took away all tumor.
Since august, we begin chemotherapy with Actinomycine D and Vincristine.
But she doesn't support the Actino, she made 2 veino-occlusive illness, so the doctors decide to change the treatment.
We have 1 and half of treatment, they propose us the "Endoxan".
we have to decide if we stop the chemotherapy or we continue.
And we have to decide until this saturday.
It's a true dilemma.

Have you the same case in States?
What do you think of?

I'am really anxious, and i'm very afraid of the "Endoxan" within the side effects.

Thanks a lot and sorry for my english!!!
