3rd time

My partners son is 13 and in the last year has had all froms of treatment, the cancer has returned again after amputation of his leg and we were told that he could start a trial drug CP-751,871, but two days later they say "he is too young" and they MIGHT be able to try a different drug, but as yet nothing. at present he is in hospital because of the pain and I am very concerned that this cancer is eating him away and nobody seems to be doing anything. Can anyone help please.
