A Systematic Review on the Role of Postoperative Radiotherapy in Pelvic Ewing Sarcoma

Ewing Sarcoma of the pelvis has poorer outcomes than other anatomical sites, with complex anatomy often precluding resection with wide margins. The role of postoperative radiotherapy (RT) in improving outcomes remains undefined. A systematic review using Medline, Embase and Cochrane databases (1972-April 2024) evaluated postoperative RT's impact on local recurrence, event-free survival and overall survival. Twenty-nine retrospective studies (21 to 296 patients) met inclusion criteria, with 28 rated good quality.
