Pediatric brain tumors as a developmental disease

Area of Science:

• Neuro-oncology
• Developmental biology
• Pediatric oncology

Background:

• Brain tumors are the most common solid cancers in children.
• The origins of pediatric brain tumors are poorly understood, with few environmental links.
• A developmental basis for pediatric brain tumors is increasingly considered.

Purpose of the Study:

• To explore the hypothesis that pediatric brain tumors result from aberrant developmental processes.
• To review the influence of this developmental hypothesis on clinical management.

Main Methods:

• Review of current literature linking developmental abnormalities and cancer predisposition syndromes.
• Analysis of genes involved in both pediatric brain tumor oncogenesis and developmental processes.
• Examination of cerebral organoid models mimicking early brain development.

Main Results:

• Pediatric brain tumors often co-occur with developmental abnormalities.
• Genes crucial for brain development are implicated in pediatric brain tumor formation.
• Cerebral organoid models suggest early developmental events predispose to oncogenesis.

Conclusions:

• A strong link exists between early brain development and oncogenesis in pediatric brain tumors.
• Tumor initiation may involve the hijacking of normal brain developmental pathways.
• Interdisciplinary collaboration between neuroscientists and oncologists is crucial for advancing knowledge.
