Which Factors Are Associated with Local Control and Survival of Patients with Localized Pelvic Ewing’s Sarcoma? A Retrospective Analysis of Data from the Euro-EWING99 Trial

摘要

Local treatment of pelvic Ewing’s sarcoma may be challenging, and intergroup studies have focused on improving systemic treatments rather than prospectively evaluating aspects of local tumor control. The Euro-EWING99 trial provided a substantial number of patients with localized pelvic tumors treated with the same chemotherapy protocol. Because local control included surgical resection, radiation therapy, or a combination of both, we wanted to investigate local control and survival with respect to the local modality in this study cohort.
