In this article (Clin Cancer Res 2016;22:4356–65), which was published in the September 1, 2016, issue of Clinical Cancer Research (1), EURO EWING Consortium funding was incorrectly listed in the grant support statement. The full statement should read as follows: “This research was supported by grants of the Madeleine Schickedanz Kinderkrebs-Stiftung, Schornsteinfeger helfen krebskranken Kindern, German Cancer Aid to UD (DKH 108128) and the EraNet consortium PrOspectiveVAalidationofBiomarkersinEwingSarcoma (PROVABES ERA-Net-TRANSCAN (01KT1310)). This project has received funding from the European Union's Seventh Framework Programme for research, technological development and demonstration under grant agreement no 602856 (to M. Metzler and U. Dirksen).” The authors regret this error.
