Pediatric brain tumors represent a diverse group of neoplasms that arise within the central nervous system of children and adolescents. While relatively rare compared to adult brain tumors, they remain the leading cause of cancer-related mortality in children, highlighting the urgent need for improved understanding and management of these complex diseases. Pediatric brain tumors present unique challenges due to factors such as age-related differences in tumor biology, treatmentrelated toxicities, and long-term effects on neurodevelopment. Despite these challenges, recent advancements in multidisciplinary care and targeted therapies offer hope for improved outcomes and quality of life for pediatric patients and their families.
One of the distinguishing features of pediatric brain tumors is their histological and molecular heterogeneity. Unlike adult brain tumors, which are primarily composed of gliomas, pediatric brain tumors encompass a broad spectrum of histological subtypes, including embryonal tumors (e.g., medulloblastoma, atypical teratoid/rhabdoid tumor), gliomas (e.g., pilocytic astrocytoma, diffuse intrinsic pontine glioma), and other rare entities. Each tumor subtype exhibits unique genetic alterations, clinical presentations, and treatment responses, necessitating tailored approaches to diagnosis and therapy. Central to the management of pediatric brain tumors is the integration of multidisciplinary care involving neurosurgery, radiation oncology, medical oncology, neurology, neuropsychology, and supportive care services. Surgical resection remains the primary treatment modality for most pediatric brain tumors, aiming to achieve maximal safe resection while preserving neurological function. Advances in neurosurgical techniques, such as intraoperative neuro-navigation, awake craniotomy, and minimally invasive approaches, have improved surgical outcomes and reduced morbidity in pediatric patients.
Following surgery, adjuvant therapies such as radiation therapy and chemotherapy are often employed to target residual tumor cells and prevent disease recurrence. However, the developing brain in pediatric patients is particularly vulnerable to the toxic effects of these treatments, which can lead to long-term neurocognitive deficits, endocrine dysfunction, and secondary malignancies. To mitigate these risks, modern treatment protocols emphasize the use of risk-adapted therapy regimens that balance therapeutic efficacy with minimizing treatmentrelated toxicity. For example, conformal radiation techniques such as intensity-modulated radiotherapy (IMRT) and proton beam therapy allow for precise targeting of tumor tissue while sparing adjacent normal brain structures, reducing the risk of neurocognitive impairment. In recent years, targeted therapies have emerged as promising treatment options for certain subtypes of pediatric brain tumors. Molecular profiling of tumor tissue has revealed specific genetic alterations and signaling pathways dysregulated in pediatric brain tumors, paving the way for the development of targeted inhibitors and immunotherapies. For example, inhibitors targeting the sonic hedgehog (SHH) pathway have shown efficacy in treating medulloblastoma, a common pediatric brain tumor subtype. Similarly, immunotherapies such as checkpoint inhibitors and chimeric antigen receptor (CAR) T-cell therapy are being investigated for their potential in treating pediatric brain tumors, offering more precise and less toxic treatment options compared to conventional chemotherapy and radiation therapy.
Pediatric brain tumors present unique challenges due to their histological diversity, treatment-related toxicities, and impact on neurodevelopment. However, recent advancements in multidisciplinary care and targeted therapies offer hope for improved outcomes and quality of life for pediatric patients. By integrating cutting-edge research with compassionate clinical care, we strive to navigate the landscape of pediatric brain tumors and pave the way for a brighter future for children facing these formidable diseases.
