Methylation Profiling of Medulloblastoma in a Clinical Setting Permits Sub-Classification and Reveals New Outcome Predictions

In this study, we report the first examination of Medulloblastoma (MB) methylation patterns in Arab world, using an extensive primary tumor cohort in tertiray care center. We assessed DNA methylation patterns to sub-classify clinical MB cases and their amenability to clinical applications from archival biopsy material (FPPE). We herein establish methylation events as clinically useful biomarkers and demonstrate how their incorporation into current risk-stratification schemes could significantly improve the accuracy of survival predictions in clinical setting. This holds potential for future precision therapeutic approaches aimed at improving the outcomes of afflicted MB patients. experimental retrospective
