Central nervous system tumors in children

Area of Science:

• Pediatric Oncology
• Neuro-oncology
• Epidemiology

Background:

• Central nervous system (CNS) neoplasms are a significant cause of morbidity and mortality in children.
• Understanding the epidemiology and outcomes of these tumors is crucial for improving patient care.

Purpose of the Study:

• To analyze the incidence, characteristics, and survival outcomes of pediatric CNS neoplasms.
• To differentiate between intracranial and intraspinal tumors in terms of histology, demographics, and prognosis.

Main Methods:

• Retrospective analysis of 488 pediatric CNS neoplasms diagnosed over a 39-year period.
• Categorization of tumors into intracranial (467) and intraspinal (21) types.
• Detailed examination of histological types, age at diagnosis, sex, anatomical location, and survival data.

Main Results:

• Common intracranial tumors included astrocytoma (28%), medulloblastoma (25%), and ependymal neoplasms (9%).
• Median age at diagnosis was 6 years (male:female ratio 1.3:1) with a mean survival of 53.4 months.
• For intraspinal tumors, astrocytoma (47%) and ependymal neoplasms (24%) were most frequent, with a median age of 10 years (1:1 ratio) and average survival of 54.1 months.

Conclusions:

• Tumor type and location significantly influence survival in pediatric CNS neoplasms.
• Intracranial and intraspinal tumors exhibit distinct epidemiological profiles and survival patterns.
• Comprehensive analysis provides valuable insights for pediatric neuro-oncology research and clinical practice.
