Abstract

Introduction More than a third of children with ependymoma experience relapse, and despite multimodal treatment, less than 25% of them can then achieve long-term survival. Prognostic factors for patients who relapse have not been extensively analyzed. Patients and methods We retrospectively analyzed 82 patients from four pediatric oncology European institutions in order to identify prognostic factors and influence of treatment modalities in relapsed ependymoma. Results First relapse occurred after a median of 19 months (1 month-16 years). Five-year progression-free survival and overall survival of the cohort were 17% and 27.6%, respectively. Survival was statistically significantly higher for patients achieving gross total resection. No survival benefit was seen for children receiving chemotherapy whereas patients who were amenable to some form of reirradiation had a better outcome. Objective responses were found in more than 25% of patients receiving oral etoposide, temozolomide, or vincristine/etoposide/cyclophosphamide regimens. Multivariate analysis confirmed that patients with mixed relapses, no surgery at relapse, and receiving chemotherapy did worse (hazard ratio=3.6, 3.3, and 1.7, respectively, all p
