Here we give a brief overview on the histopathological and clinical diversity of choroid plexus tumors and their genetic and epigenetic heterogeneity. Preliminary data indicate that choroid plexus carcinomas comprise at least two epigenetic subgroups, one of which is associated with TP53 mutation status. These findings strongly encourage us to further investigate the genetic and epigenetic heterogeneity in a larger cohort and to align molecular subgroup status with clinical annotations, in order to identify prognostic markers that may also aid stratification within future international trials.","PeriodicalId":94157,"journal":{"name":"Neuro-oncology advances","volume":null,"pages":null},"PeriodicalIF":3.7,"publicationDate":"2024-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141679118","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
