What is Pediatric High-Grade Glioma?
Pediatric High-Grade Glioma (pHGG) represents a formidable challenge in pediatric oncology. These aggressive brain tumors arise from glial cells in the central nervous system and are known for their fast-growing nature and ability to infiltrate nearby brain tissue. Pediatric high-grade brain tumors can be found almost anywhere within the Central Nervous System; however, they are found most within the upper part of the brain. Although pHGG is relatively rare, accounting for only a small percentage of pediatric brain tumors, it can devastate a child’s health and well-being. This guide will discuss various aspects of pHGG, including background on the disease, diagnosis, and treatment options. Our goal is to empower you with knowledge, foster hope, and guide you through this challenging journey of Pediatric High-Grade Glioma.
How Common are Pediatric High-Grade Gliomas?
- The incidence of pHGGs has been calculated as 1.1–1.78 per 100,000 children.
- Despite their low incidence, pHGGs are responsible for over 40% of all childhood brain tumor death, and overall, they are the more common cause of tumor-related death for children.
- The highest incidence of these tumors in pediatrics appears to occur in children aged 15 to 19 years.
What is the Prognosis for Pediatric High-Grade Glioma?
- There is a 3-year progression-free survival of about 11%.
- The five-year survival rate for high-grade gliomas in children is less than 20% and depends on individual prognosis.
What are the Symptoms of Pediatric High-Grade Glioma?
- Common symptoms include persistent headaches, seizures, vomiting, changes in vision, and difficulty with balance or coordination.
- It is important to note that these symptoms can vary depending on the location and size of the tumor.
Diagnosis
Pediatric high-grade gliomas encompass a group of malignant brain tumors characterized by their rapid growth and infiltrative nature. Unlike their adult counterparts, these tumors tend to exhibit distinct molecular features, emphasizing the need for specialized approaches in diagnosis and treatment.
Typically, diagnosing pHGG involves a combination of imaging tests, such as MRI or CT scans, and a biopsy to confirm the presence of cancerous cells.
A thorough evaluation is essential, typically involving several diagnostic tools:
Clinical Presentation: pHGG often presents with nonspecific symptoms, making early diagnosis challenging. Symptoms may include persistent headaches, seizures, and neurological deficits, requiring vigilant observation by parents and healthcare providers.
Diagnostic Imaging: Advanced imaging techniques, such as Magnetic Resonance Imaging (MRI) and Computed Tomography (CT) scans, play a pivotal role in visualizing the tumor’s location, size, and characteristics. These images are instrumental in treatment planning.
Biopsy and Molecular Testing: Confirming the diagnosis involves a biopsy, wherein a small sample of the tumor is extracted for analysis. Molecular testing is becoming increasingly crucial, offering insights into specific genetic mutations that guide treatment decisions. Understanding the molecular profile can also contribute to prognosis assessment.
Treatment Options for Pediatric High-Grade Glioma
Treating Pediatric High-Grade Glioma requires a multidisciplinary approach involving a team of oncologists, neurosurgeons, radiation therapists, and other specialists. The treatment plan will depend on various factors, including the subtype of pHGG, the tumor’s location and size, and the child’s overall health.
The patient’s physician may consider one or more treatment options:
Surgery: Surgical intervention aims to remove as much of the tumor as possible without compromising critical brain functions. The challenges lie in the delicate nature of pediatric brain surgery, with precision and minimizing damage to surrounding healthy tissue being paramount.
Radiation Therapy: Radiation therapy is a standard pHGG treatment. While effective, it poses challenges in pediatric cases due to the developing nature of the brain. Advances in targeted radiation delivery seek to minimize adverse effects while maximizing therapeutic impact.
Chemotherapy: Various chemotherapy regimens, often combined with radiation therapy, are employed to target cancer cells and impede their growth. The choice of chemotherapy depends on the tumor type and the individual patient’s response.
Targeted Therapies: Emerging targeted therapies aim to exploit specific molecular vulnerabilities within the tumor cells. These therapies represent a promising frontier, with ongoing clinical trials exploring their efficacy in pediatric gliomas.
Clinical Trials: In some cases, participation in clinical trials may offer promising experimental treatments that are not yet widely available. This option can be appropriate for any stage of cancer, depending on ongoing trials, rather than seen as a last resort. It is essential to research and talk to your healthcare provider about all clinical trial options that you may qualify for.
