Medulloblastomas
Medulloblastomas are the most common malignant brain tumors in children. They arise in the cerebellum and can spread through the CSF pathways. Complete surgical resection followed by craniospinal irradiation is the main treatment approach. CSI provides improved local and systemic tumor control compared to other radiation techniques based on early studies. Medulloblastomas are highly radiosensitive tumors, making radiation an important part of management, though younger patients and those with residual disease or metastasis have poorer outcomes.
