Recent developments and current concepts in medulloblastoma.

Medulloblastoma is the most common malignant brain tumor of childhood. While prognosis has significantly improved in the last decades with multimodal therapy including surgery, radiotherapy, and chemotherapy, one third of patients still succumb to their disease. Further research is needed to find more efficient treatment strategies for prognostically unfavorable patient groups and to minimize long-term sequelae of tumor treatment. This review gives a summary of the current state of treatment concepts including an outlook on the near future. We describe recent advances in the understanding of molecular mechanisms, their potential impact on risk stratification in upcoming clinical trials, and perspectives for the clinical implementation of targeted therapies.
