Diffuse Intrinsic Pontine Glioma: Guide
DIPG is a type of brainstem glioma located in the pons, a part of the brainstem responsible for essential bodily functions such as breathing, sleeping, and swallowing. Its location makes surgical intervention challenging, and its diffuse nature means that it infiltrates healthy brain tissue, complicating treatment efforts.
Symptoms of Diffuse Intrinsic Pontine Glioma
Early Signs and Symptoms
DIPG symptoms typically manifest rapidly and can include:
- Cranial nerve palsies: Resulting in facial weakness, eye movement problems, or hearing loss.
- Motor dysfunction: This includes weakness or coordination issues, particularly affecting the arms and legs.
- Ataxia: Difficulty with balance and coordination.
- Dysphagia and Dysarthria: Issues with swallowing and speech due to muscle weakness.
- Headaches and Nausea: Often resulting from increased intracranial pressure.
These symptoms often progress quickly, necessitating prompt medical evaluation.

Get A Second OpinionCauses and Risk Factors
The precise cause of DIPG remains largely unknown. However, research suggests that genetic mutations play a role in tumour development. Unlike many cancers, environmental factors and inherited genetic conditions are not commonly associated with DIPG.
Age is a significant risk factor, with most cases occurring in children aged 5 to 10. Due to the disease's unclear aetiology, there is no known method for prevention.
Diagnosis of Diffuse Intrinsic Pontine Glioma
Diagnostic Imaging Techniques
The diagnosis of DIPG primarily relies on imaging studies:
- Magnetic Resonance Imaging (MRI): This is the gold standard for DIPG diagnosis. MRI scans provide detailed images of the brain and can help distinguish DIPG from other types of brain tumours.
- Biopsy: Although not routinely performed due to the tumour's sensitive location, a biopsy may be conducted to obtain tumour tissue for molecular testing, which can guide treatment decisions.
Treatment Options for Diffuse Intrinsic Pontine Glioma
Radiation Therapy
Radiation therapy remains the cornerstone of DIPG treatment. It can temporarily alleviate symptoms and improve quality of life, but it is not curative. The standard protocol involves fractionated external beam radiation therapy, which targets the tumour with high-energy rays over several weeks.
Experimental Therapies and Clinical Trials
Given the poor prognosis associated with DIPG, participation in clinical trials is often recommended. Novel therapies under investigation include:
- Targeted therapies: Drugs designed to attack specific genetic mutations within the tumour.
- Immunotherapy: Approaches that harness the body's immune system to combat cancer cells.
- Convection-enhanced delivery (CED): A technique that delivers chemotherapy directly to the tumour site.
These investigational treatments are continually evaluated in clinical trials, offering hope for future breakthroughs.

Book an AppointmentPrognosis and Survival Rates
The prognosis for DIPG remains dire, with a median survival time of less than one-year post-diagnosis. Despite advancements in understanding the molecular biology of DIPG, survival rates have not significantly improved over the past few decades.
Factors influencing prognosis include:
- Tumor size and location
- Patient age
- Response to Initial Radiation Therapy
While long-term survival is rare, ongoing research aims to improve outcomes for affected children.
Support and Resources for Families
Coping with a DIPG diagnosis is incredibly challenging for both patients and their families. Access to support services is crucial for navigating the emotional and practical aspects of the disease. Resources may include:
- Counselling and psychological support: For patients and family members to manage the emotional impact.
- Palliative care services: To enhance the quality of life through symptom management and support.
- Patient advocacy groups: Offering information, support, and connection to other families facing similar challenges.
Frequently Asked Questions
1. What are the symptoms of Diffuse Intrinsic Pontine Glioma?
Symptoms may include cranial nerve dysfunction, difficulty with motor coordination, and changes in consciousness due to the tumor's location in the brainstem.
2. What causes Diffuse Intrinsic Pontine Glioma?
Causes are typically unknown, but these tumors are more common in children and arise from glial cells in the brainstem.
3. How is Diffuse Intrinsic Pontine Glioma diagnosed?
Diagnosis typically involves imaging studies such as MRI to assess tumor characteristics and location.
4. What treatment options are available for Diffuse Intrinsic Pontine Glioma?
Treatment may include radiation therapy to reduce symptoms, though prognosis is generally poor due to the aggressive nature of the tumor.
5. How does Diffuse Intrinsic Pontine Glioma relate to children?
It is one of the most common brain tumors in children, requiring urgent management and care.
