Press M1 - DKFZ-2024-01709 SP - 267–276 PY - 2025 N1 - Volume 27, Issue 1, January 2025, Pages 267–276 AB - Ependymoma (EPN) is not a uniform disease but represents different disease types with biological and clinical heterogeneity. However, the pattern of when and where different types of EPN relapse is not yet comprehensively described.We assembled 269 relapsed intracranial EPN from pediatric (n=233) and adult (n=36) patients from European and Northern American cohorts and correlated DNA methylation patterns and copy-number alterations with clinical information.The cohort comprised the following molecular EPN types: PF-EPN-A (n=177), ST-EPN-ZFTA (n=45), PF-EPN-B (n=31), PF-EPN-SE (n=12), and ST-EPN-YAP (n=4). First relapses of PF-EPN-B (PF: posterior-fossa) and PF-EPN-SE (SE: subependymoma) occurred later than of PF-EPN-A, ST-EPN-YAP (ST: supratentorial), or ST-EPN-ZFTA (median time to relapse: 4.3 and 6.0 years vs. 1.9/1.0/2.4 years; p<0.01). Metastatic or combined recurrences in PF-EPN-B and -A more often involved the spinal cord than in ST-EPN-ZFTA (72.7 KW - ependymoma (Other) KW - metastatic (Other) KW - recurrence (Other) KW - relapse (Other) LB - PUB:(DE-HGF)16 C6 - pmid:39171767 DO - DOI:10.1093/neuonc/noae166 UR - https://inrepo02.dkfz.de/record/292426 ER -
