This study aimed to prospectively evaluate clinical, histopathological and molecular variables for outcome prediction in medulloblastoma patients. Patients from the HIT2000 cooperative clinical trial were prospectively enrolled based on the availability of sufficient tumor material and complete clinical information. This revealed a cohort of 184 patients(More)
AIMS Wnt activation in medulloblastomas is associated with good outcome. Upfront testing and risk-adapted stratification of patients will be done in future clinical studies. In a cohort of 186 paediatric medulloblastomas our aim was to identify the optimal methods in standard clinical practice to detect this subgroup. METHODS Nuclear accumulation of(More)
PURPOSE To improve stratification of risk-adapted treatment for non-metastatic (M0), standard-risk medulloblastoma patients by prospective evaluation of biomarkers of reported biological or prognostic significance, alongside clinico-pathological variables, within the multi-center HIT-SIOP-PNET4 trial. METHODS Formalin-fixed paraffin-embedded tumor tissues(More)
Rosette-forming glioneuronal tumors (RGNTs) are rare glioneuronal tumors of the fourth ventricle region that preferentially affect young adults. Despite their histologic similarity with pilocytic astrocytomas (PAs), RGNTs do not harbor KIAA1549-BRAF fusions or BRAF mutations, which represent the most common genetic alteration in PAs. Recently, mutations(More)
Papillary tumors of the pineal region (PTPR) are recognized as a distinct entity in the World Health Organization classification of CNS tumors. Papillary tumors of the pineal region frequently show loss of chromosome 10, but no studies have investigated possible target genes on this chromosome. Chromosome 10 harbors the PTEN (phosphatase and tensin homolog)(More)
Cribriform neuroepithelial tumors (CRINET) are one of several recently characterized entities in the broad spectrum of solid tumors with SMARCB1-INI1 loss. This neoplasm seems to be exceedingly rare and displays unique neuropathologic and clinical features. To date, only a few cases of CRINET have been characterized from a molecular point of view. In this(More)
