Intracranial neoplasms in infants

Area of Science:

• Pediatric Oncology
• Neuro-oncology
• Epidemiology of Childhood Cancers

Background:

• Primary intracranial neoplasms are rare but devastating in infants.
• Understanding the epidemiology of these tumors is crucial for diagnosis and treatment.
• Historical data provides valuable insights into disease patterns and outcomes.

Purpose of the Study:

• To describe the incidence, characteristics, and survival of primary intracranial neoplasms in infants.
• To analyze the relationship between tumor type, location, and patient outcomes.
• To present neurological function data for long-term survivors.

Main Methods:

• Retrospective analysis of 54 infant primary intracranial neoplasms diagnosed between 1935 and 1974 in Connecticut.
• Data collection included patient demographics, tumor histopathology, location, clinical presentation, and survival.
• Statistical analysis to determine frequencies, averages, and survival rates.

Main Results:

• Fifty-four cases occurred in infants aged 18 months or younger over 40 years.
• Medulloblastomas (30%) and ependymal neoplasms (16%) were the most frequent types.
• Common symptoms included vomiting; large head circumference was the most frequent physical finding. Average survival was 43 months.

Conclusions:

• Infant brain tumors exhibit specific histopathological and topographical distributions.
• Early identification of symptoms like vomiting and physical findings like increased head circumference is vital.
• Survival rates vary significantly based on tumor type and location, highlighting the need for tailored therapeutic strategies.
