The purpose of this page is to provide references to regimens that are obsolete, outdated, or of historical interest only. As a general rule, this includes the inferior arm(s) of a randomized study, unless said regimens continue to be recommended by trustworthy sources such as the NCCN Guidelines. Is there a regimen missing from this list? See the main pediatric Ewing sarcoma page for current regimens.
