St. Jude Releases Medulloblastoma Risk Model and MB‑Meta Portal to Enable Treatment De‑Escalation

A new St. Jude analysis of nearly 900 cases suggests many children could receive gentler therapy without sacrificing survival.

Overview

  • Researchers harmonized clinical, genomic and methylation data from three medulloblastoma trials totaling nearly 900 pediatric patients.
  • The integrated analysis defined four actionable treatment groups using predictors that include G3/G4 subdivision by chromosome changes, methylation subgroup and MYC amplification.
  • Retrospective results indicate about 40% of patients could receive lower craniospinal radiation and most could receive less chemotherapy with comparable survival outcomes.
  • St. Jude introduced the MB‑meta web portal, a point‑and‑click tool that generates predicted survival curves based on selected clinical, demographic and molecular features.
  • Giles Robinson is launching a prospective trial to validate the risk‑based approach, and portal‑driven exploration identified two novel KBTBD4 mutation subgroups for further study.
