Group 4 Medulloblastomas of Early Childhood Treated With High‐Dose Chemotherapy‐ and Craniospinal Irradiation‐Sparing Approach

Key Points

Assess the impact of high-dose chemotherapy on relapse rates in young children with Group 4 medulloblastomas.
Evaluated relapse rate in patients treated with high-dose chemotherapy for Group 4 MB
Compared outcomes with conventional chemotherapy
Monitored survivors' need for radiotherapy
High-dose chemotherapy yielded a 52.6% relapse rate
More than two-thirds of patients responded to salvage radiotherapy
Half of the survivors did not receive radiotherapy

Abstract

High dose chemotherapy for Group 4 MB was associated with a relapse rate of 52.6%, which favorably compares to data reported with conventional chemotherapy. Salvage radiotherapy retrieved more than two-thirds of the patients. Half of the survivors never received radiotherapy. Such an approach may represent an alternative to upfront CSI for young children with Group 4 MB.
