Abstract 1140: Genes preserving stem cell state in group 3 medulloblastoma brain tumor initiating cells contribute to therapy evasion and relapse

Abstract Medulloblastoma (MB) is the most common malignant pediatric brain tumor. Of current molecular subgroups, Group 3 patients face the highest incidence of metastatic spread and overall patient survival of less than 50%. Current clinical trials for recurrent MB patients based on genomic profiles of primary, treatment-naïve tumors provide limited clinical benefit, since recurrent metastatic MBs are highly genetically …
