Critical impact of radiotherapy protocol compliance and quality in the treatment of retroperitoneal sarcomas: Results from the EORTC 62092‐22092 STRASS trial

The European Organization for Research and Treatment of Cancer 22092‐62092 STRASS trial failed to demonstrate the superiority of neoadjuvant radiotherapy (RT) over surgery alone in patients with retroperitoneal sarcoma. Therefore, an RT quality‐assurance program was added to the study protocol to detect and correct RT deviations. The authors report results from the trial RT quality‐assurance program and its potential effect on patient outcomes.
