Brain Tumor in Children – Symptoms, Diagnosis and Treatment

Receiving a diagnosis of a brain tumor in children can be one of the most frightening moments for any parent. However, in the realm of pediatric neuro-oncology, advancements are continuously bringing new hope. Understanding the early signs of brain tumor in children, the intricate diagnostic processes, and the array of sophisticated treatment options available today is paramount. This blog aims to demystify this complex topic, offering clear, compassionate, and actionable information for families worldwide.

What are Pediatric Brain Tumors?

A pediatric brain tumor is an abnormal growth of cells within a child’s brain or spinal cord. Unlike adult brain tumors, which are often malignant, many childhood brain tumors are benign (non-cancerous). However, even benign tumors can be life-threatening if their size and location put pressure on critical brain structures. These tumors are the second most common type of cancer in children after leukemia, affecting over 5,000 children annually.

Understanding how brain tumor occurs in children largely points to random genetic mutations during a child’s development, rather than lifestyle or environmental factors. It’s crucial for parents to know that these diagnoses are rarely due to anything they did or didn’t do.

Spotting the Signs: Symptoms of Brain Tumor in Children

The symptoms of brain tumor in children can be subtle and often mimic common childhood ailments, making early detection a challenge. Vigilance and awareness of persistent or worsening symptoms are key. The specific signs often depend on the tumor’s location, size, and growth rate. Similar to younger children, the exact causes of brain tumor in children and teenagers are often unknown but are generally linked to random genetic mutations. Genetic syndromes are a minor risk factor.

Here are some common signs of brain tumor in children to watch for:

• Persistent Headaches: Especially those that are worse in the morning, wake the child from sleep, or are accompanied by nausea and vomiting.
• Nausea and Vomiting: Often occurring in the morning and unrelated to food, indicating increased intracranial pressure.
• Vision Changes: Blurred vision, double vision, or difficulty tracking objects, if the tumor affects the optic pathways.
• Balance and Coordination Problems: Unexplained clumsiness, difficulty walking (ataxia), or problems with fine motor skills.
• Seizures: Can be a significant indicator, especially if there’s no prior history.
• Behavioral and Cognitive Changes: Irritability, lethargy, personality shifts, or a decline in academic performance.
• Increased Head Size (in infants): In very young children whose skull bones haven’t fused, a tumor can cause an abnormal increase in head circumference (macrocephaly).

If you observe any of these symptoms, particularly if they are persistent or concerning, seek prompt medical evaluation.

Pediatric Brain Tumor Diagnosis

Diagnosing a brain tumor in children is a meticulous process involving a series of specialized tests to confirm the tumor’s presence, type, location, and potential spread.

The diagnostic journey typically includes:

• Physical and Neurological Exam: A thorough check of reflexes, coordination, vision, and mental status provides initial clues.
• Imaging Tests:
  • MRI (Magnetic Resonance Imaging): The gold standard for pediatric brain tumor diagnosis, providing detailed images of the brain and spinal cord, including the tumor’s relationship to vital structures.
  • CT (Computed Tomography) Scan: A faster option often used in emergencies or to visualize bony structures.
• Biopsy: This is the definitive test. A pediatric neurosurgeon carefully removes a tissue sample from the tumor for laboratory analysis. This determines the tumor’s specific type and grade.
  • Stereotactic Biopsy: Uses advanced imaging to guide a needle to the tumor.
  • Open Biopsy: Involves surgical removal of a larger portion or the entire tumor.
• Spinal Tap (Lumbar Puncture): To check for tumor cells in the cerebrospinal fluid (CSF), especially if there’s a risk of spread within the central nervous system.
• Blood Tests: May be used to detect tumor markers or assess overall health.

Pediatric brain tumors are graded from I to IV. Grade I and II tumors are generally low-grade and slow-growing, often benign. Grade III and IV tumors are high-grade, aggressive, and often malignant.

Treatment for Brain Tumors in Children

The childhood brain tumor treatment options are highly individualized, tailored to the tumor’s type, grade, location, the child’s age, and overall health. A multidisciplinary team of specialists, including pediatric neurosurgeons, oncologists, and radiation oncologists, collaborates to create the most effective plan.

1. Surgery: Often the first line of treatment. The goal is to remove as much of the tumor as safely possible while preserving neurological function. For some benign tumors, complete surgical removal can be curative.
2. Chemotherapy: Uses powerful drugs to kill cancer cells. It’s often employed for high-grade tumors, tumors that couldn’t be fully resected, or to prevent recurrence.
3. Radiation Therapy: High-energy beams target and destroy cancer cells. For children, proton therapy is often preferred. This advanced form of radiation delivers a precise dose to the tumor, minimizing damage to surrounding healthy, developing brain tissue, thereby reducing long-term side effects like learning disabilities.
4. Targeted Therapy: These newer drugs specifically attack molecular pathways driving cancer growth, offering a more precise approach with potentially fewer side effects.
5. Immunotherapy: An emerging treatment that harnesses the child’s own immune system to recognize and fight cancer cells.
6. Autologous Stem Cell Transplant: For high-risk or relapsed tumors, high-dose chemotherapy followed by a transplant of the child’s own cryopreserved stem cells can improve outcomes.

Myth Busting: While stage 4 brain cancer timeline in adults can be very aggressive, the outlook for pediatric brain tumor survival rates has significantly improved, with a combined 5-year survival rate of approximately 75% across all types. Low-grade astrocytomas, for instance, boast over a 90% 5-year survival rate. Early diagnosis and aggressive, specialized brain tumor surgery in children and subsequent therapies are crucial.

Beyond Treatment: Recovery and Aftercare

The journey doesn’t end with treatment. Comprehensive aftercare includes rehabilitation therapies (physical, occupational, speech), educational support, and long-term follow-up with specialists to monitor for recurrence and manage potential late effects of treatment. Brain cancer seizures life expectancy can be significantly improved with proper management and ongoing care.
