This guide aims to provide Cambodian patients with a clear, concise, and comprehensive overview of glioblastoma, its treatment options in India, associated costs, and answers to frequently asked questions.

Understanding Glioblastoma

What is Glioblastoma?

Glioblastoma, also known as glioblastoma multiforme (GBM), is an aggressive type of cancer that originates in the brain or spinal cord. It arises from astrocytes, the cells that support nerve cells. GBM is known for its rapid growth and tendency to infiltrate surrounding brain tissue, making it challenging to treat.

Causes and Risk Factors

The exact cause of glioblastoma remains unclear. However, several risk factors have been identified:

• Age: Most common in older adults, though it can occur at any age.

• Radiation Exposure: Previous exposure to ionizing radiation, especially to the head, can increase risk.

• Genetic Factors: Certain inherited genetic syndromes, such as Li-Fraumeni syndrome, can elevate risk. 

Symptoms

Symptoms vary based on the tumor’s location but commonly include:

• • Persistent headaches
  • Nausea and vomiting
  • Seizures
  • Memory loss
  • Personality changes
  • Difficulty speaking or understanding language
  • Vision problems

• Weakness on one side of the body 

Diagnosis and Treatment of Glioblastoma

Diagnostic Procedures

Timely and accurate diagnosis is the first and most crucial step in the management of glioblastoma. Because glioblastoma is an aggressive and fast-growing brain tumor, a precise understanding of its size, location, and biological behavior is essential to chart the best course of treatment.

Below are the standard diagnostic steps involved:

1. Neurological Examination

• • This is the first evaluation done when a brain tumor is suspected.
  • The neurologist checks for: 
    • Vision problems, such as double or blurred vision.
    • Hearing issues.
    • Muscle strength and reflexes, particularly in the arms and legs.
    • Coordination and balance—looking for signs of instability.
    • Cognitive functions, including speech, memory, and understanding. 
• Abnormal results in this exam may suggest the presence of a brain tumor, prompting further investigations.
  

2. Imaging Tests

• Magnetic Resonance Imaging (MRI) is the gold standard for diagnosing glioblastoma.
• • MRI provides detailed images of the brain’s soft tissues.
  • A contrast dye called gadolinium is often injected to highlight abnormal tumor areas.

• Special MRI techniques like MR spectroscopy, functional MRI (fMRI), and perfusion imaging may be used to further characterize the tumor. 

• Computed Tomography (CT) Scan: 

• • • May be used if MRI is not available or to detect calcifications or bleeding in the brain.
    • It’s faster than MRI and sometimes used in emergency settings.

• These imaging tests not only detect the tumor but also help in planning surgery or radiation.
  

3. Biopsy

• A biopsy is performed to obtain a small sample of the tumor tissue.
• The sample is examined under a microscope to confirm the diagnosis of glioblastoma and to analyze its genetic and molecular characteristics.
• Biopsies can be done during surgery (open biopsy) or using a minimally invasive needle technique (stereotactic biopsy).
• A biopsy provides valuable information such as the tumor grade and molecular markers like IDH mutation status, MGMT promoter methylation, and EGFR amplification, which can influence treatment decisions.

Treatment Options in India: Multidisciplinary and World-Class Care

India has become a hub for advanced cancer treatment, including complex brain tumors like glioblastoma. Most leading hospitals in India employ a multidisciplinary approach, where neurosurgeons, oncologists, radiologists, pathologists, and rehabilitation experts collaborate to develop comprehensive and personalized treatment plans.

Here’s an overview of the available treatment options:

1. Surgery

• To remove as much of the tumor as safely possible without damaging critical brain areas.

• • Known as maximal safe resection, surgery remains the first step in treating glioblastoma.
  • Advanced techniques used in India include:

• Awake Craniotomy: Patient remains conscious during surgery so that surgeons can test speech or movement functions in real-time, minimizing the risk of brain damage.

• Intraoperative MRI/Navigation: Helps the surgeon remove the tumor more precisely.

• Fluorescence-guided surgery (5-ALA): A special dye highlights tumor cells under blue light to improve accuracy.

• While complete removal of the tumor is often not possible due to its infiltrative nature, removing as much of it as possible significantly improves outcomes. 

2. Radiation Therapy

• Usually started within 3–4 weeks after surgery to destroy remaining cancer cells.
• India offers access to advanced forms of radiation therapy, such as: 
• External Beam Radiation Therapy (EBRT): The most common method, where high-energy beams are directed at the tumor site.

• Stereotactic Radiosurgery (SRS): A highly focused and precise form of radiation, especially useful when surgery isn’t an option or for treating recurrent glioblastoma.

• Intensity-Modulated Radiation Therapy (IMRT): Delivers radiation precisely to the tumor, minimizing damage to nearby healthy tissue.

• Radiation usually lasts for about 6 weeks, with sessions given 5 days a week.
  

3. Chemotherapy

• • Temozolomide (TMZ) is the standard chemotherapy drug used for glioblastoma.
    • It is an oral medication taken daily during and after radiation therapy.
    • The drug works by damaging the DNA of cancer cells, preventing them from multiplying.
  • Most patients continue with maintenance chemotherapy (usually 6 cycles) after radiation to keep the tumor in check.

• Chemotherapy may be modified based on molecular testing of the tumor (such as MGMT methylation status), which helps predict how well the patient will respond to the drug.
  

4. Targeted Therapy

• • This involves drugs that specifically target genetic changes or proteins in the tumor cells.

• Commonly used targeted therapies include: 

• Bevacizumab (Avastin): An anti-angiogenic drug that blocks the growth of blood vessels feeding the tumor.

• EGFR inhibitors: For tumors with overexpression or mutation of the EGFR gene.

• While not curative, targeted therapy can help control tumor progression, especially in recurrent glioblastoma.
  

5. Immunotherapy

• • A relatively new and promising area in glioblastoma treatment.
  • CAR-T cell therapy, immune checkpoint inhibitors, and tumor vaccines are being tested in clinical trials across India.
  • The goal is to stimulate the patient’s immune system to recognize and destroy cancer cells.

• Though still in the experimental stage for glioblastoma, some Indian hospitals participate in global clinical trials and offer these treatments under special protocols.
  

6. Supportive and Palliative Care

• • Given the aggressive nature of glioblastoma, symptom management is critical.
  • Patients may need:
    • Anti-seizure medications
    • Steroids to reduce brain swelling
    • Physiotherapy and rehabilitation to restore function
    • Speech and cognitive therapy

• Palliative care teams ensure that the patient’s pain, emotional stress, and quality of life are well managed throughout treatment.
