This high-grade neuroepithelial tumour of the posterior fossa can develop at any age during childhood, adolescence and even adulthood, often spreading via cerebrospinal fluid. While most MB cases are sporadic, they can be associated with genetic predisposition syndromes. Although these genetic mutations present potential therapeutic targets, the limited number of mutations and few existing therapies aimed at these neoantigens pose significant challenges. Despite aggressive multimodal treatment approaches, approximately 30% of patients ultimately succumb to MB, and survivors frequently face long-term side effects that severely impact their quality of life. MB harbours unique molecular factors, necessitating careful consideration of therapeutic targets such as the blood-brain barrier, tumour microenvironment, and the differing responses of cancer stem cells versus bulk tumour tissue. Conventional treatment typically involves maximal safe resection, risk-adapted chemotherapy, and/or radiation craniospinal irradiation. While there is general agreement on the benefits of chemotherapy for MB patients, adverse side effects remain prevalent, underscoring the need for alternative therapeutic strategies. Given the heterogeneous nature of MBs and the lack of salvage treatment, immunotherapy has emerged as a promising novel treatment avenue. This personalized approach aims to enhance specificity and potentially reduce side effects.
