We described the treatment and outcome for patients with PM RMS and investigated the prognostic value of risk factors. We scored PM site by originating site and by highest risk extension. Methods Patients with PM RMS were treated within the European pediatric Soft tissue sarcoma Study Group (EpSSG) RMS 2005 study with risk-adapted, multi-modal treatment. Results Three-hundred-eighty-one patients with PM RMS were included. Radiotherapy was administered in 359 patients (77 with surgery). After a median follow-up of 75 months, 5-year event-free survival was 60% (95% confidence interval (CI) 55%–65%), 5-year overall survival was 65% (95% CI 60%–70%). Conclusions The outcome for patients with PM RMS has not improved in comparison to previous historical studies, despite the more rigorous application of radiotherapy (94% of patients). Signs of meningeal involvement, PM site, and age at diagnosis remained prognostic risk factors.
