Hi Erica's Mom, My husband has been battling sarcoma for the past three years. His is osteo, but we have been going to the CTRC Center in San Antonio, TX for the past year doing clinical trials. We met a man there this year that has ewings sarcoma and went on a trial called AMG479. In six months his cancer was totally gone. Our Dr. is Anthony Tolcher. He has since opened a new center in San Antonio called START. I pray that Erica's scans will be good, ( I understand how totally scarey it is), but if by chance it comes back check out the trial. I can give you his name if you are interested. Sondra
