In this new report from the Children's Oncology Group, researchers identified molecular features of localized Ewing sarcoma (EWS) that were associated with relapse. In this study, patients with STAG2 mutations were at a higher risk of relapse than other patients. This work may help physicians more effectively strategize treatment for patients at high risk of relapse.
This is a prospective validation of the molecular prognostic features of patients with localized EWS receiving standard-of-care therapy on therapeutic clinical trials. Building on previous work, patients with STAG2 mutations were at high risk of relapse.
