Slide 1-

Pediatric Brain Tumors By: Aunshka Collins
Slide 2-

What is the nervous system?
Slide 3-

Central Nervous System (CNS) Brain Control center Movement, speech, memory, emotion, thoughts Interpretation of sensory information (i.e., taste, vision, hearing, touch)
Slide 4-

Central Nervous System (CNS) Spinal Cord Main pathway for information connecting the brain and the peripheral nervous system
Slide 5-

Overview of Pediatric Brain Tumors Abnormal growths or masses that occur in the brain tissue Most common solid tumor in children Under the age of 15 Represent about 20% childhood cancers Treatment and chance of recovery (i.e., prognosis) depends on the tumor: Type Location within the brain Whether it has infiltrated other brain tissue Child’s age and health
Slide 6-

Symptomology Increased head size in infants Seizures Morning headache or headache that goes away after vomiting Unusual sleepiness Alterations in vision, hearing and speech Frequent nausea Personality changes
Slide 7-

Hydrocephalus Leads to swelling of the brain
Slide 8-

Types of Pediatric Tumors The most common types of brain tumors in children are gliomas and medulloblastomas
Slide 9-

Something to Remember Pediatric CNS tumors are not staged They do not metastasize, except via cerebrospinal fluid (CSF) Therefore, spinal imaging is required in certain tumors (e.g. medulloblastoma) How serious a brain tumor is in a child depends on its grade
Slide 10-

Pediatric Grading Grade I and II (low-grade):The tumor grows slowly Rarely infiltrates into nearby tissues. Grade II can infiltrate into nearby tissues Can be cured by surgery Grade III and IV (high-grade): The tumor grows quickly Likely to infiltrate into nearby tissue Grade IV tumors usually cannot be cured/removed by surgery
Slide 11-

Astrocytoma Originate in a particular glia cell, astrocytes Most common type of glioma There are four primary types: Juvenile pilocytic astrocytoma (Grade I) Usually cystic (fluid-filled) and develops in the cerebellum Surgical removal is often the only treatment necessary Fibrillary astrocytoma (Grade II) Infiltrates into the surrounding normal brain tissue Difficult to remove by surgery difficult Anaplastic astrocytoma (Grade III) Glioblastoma multiforme (Grade IV) This is the most malignant type of astrocytoma Grows rapidly, increasing pressure in the brain
Slide 12-

Juvenile Pilocytic astrocytoma
Slide 13-

Glioblastoma Multiforme
Slide 14-

Medulloblastoma Accounts for 15% of brain tumors in children Form in the cerebellum Referred to as a infratentorial primitive neuroectodermal tumor (PNET) Can metastasize to the spinal cord Highly aggressive
Slide 15-

Medulloblastoma 4-year-old, presenting with morning vomiting
Slide 16-

Brainstem Glioma Located in the middle of the brainstem Majority of the tumors cannot be surgically removed Occur in school-aged children Symptoms include: Endocrine problems Paralysis of nerves/ muscles of the face Respiratory changes
Slide 17-

Brainstem Glioma
Slide 18-

Statistics The American Cancer Society estimates that brain and spinal cord tumors are the second most common cancers in children (after leukemia). 1 out of 4 childhood cancers More than 4,000 (CNS) tumors are diagnosed each year in children and teens. Boys develop these tumors slightly more often than girls. About 3 out of 4 children with brain tumors (all types combined) survive at least 5 years after being diagnosed. About 1,310 children younger than 15 years old are expected to die from cancer in 2013.
