What is Glioblastoma?

Glioblastoma (or Glioblastoma multiforme), often abbreviated as GBM, stands as one of the most aggressive and challenging brain tumors known to medical science. With its rapid progression and limited treatment options, it poses significant implications for affected individuals and their families. This article aims to shed light on the multifaceted nature of glioblastoma by exploring its definition, symptoms, diagnosis, and available treatment options.

What is Glioblastoma?

Glioblastoma is an invasive type of brain tumor that originates from the supportive tissue of the brain, called glial cells. It is classified as a Grade IV tumor, indicating its high malignancy and tendency to grow rapidly. Glioblastoma affects people of all ages, but it is commonly found in adults between the ages of 45 and 70.

What are the Symptoms?

Symptoms of glioblastoma vary depending on the tumor’s size, location, and influence on surrounding brain tissue. Common symptoms include:

a) Headaches: Persistent headaches that are often more intense in the morning.

b) Behavioural and memory changes: Memory loss, confusion, difficulty concentrating, personality changes, and coordination problems.

c) Seizures: Glioblastoma can cause both focal seizures, which affect specific areas of the body, and generalized seizures that impact the entire body.

d) Vision and speech problems: Blurred or double vision, difficulty speaking, or understanding speech.

e) Nausea and vomiting: Frequent and unexplained bouts of nausea and vomiting may occur.

f) Weakness or numbness: Gradual loss of strength or sensory perception, particularly on one side of the body.

How is it Diagnosed?

Diagnostic procedures aim to confirm the presence of glioblastoma and determine the extent of its growth. They typically involve:

a) Magnetic Resonance Imaging (MRI): High-resolution MRI scans are crucial in identifying the location and size of the tumor.

b) Biopsy: A surgical procedure that involves removing a small sample of the tumor for laboratory analysis. Biopsies are essential to determine the tumor’s grade and characteristics.

c) Neurological Examination: A comprehensive examination of cognitive abilities, reflexes, coordination, and sensory perception is conducted to assess the tumor’s impact on the brain.

What are the Treatment Options?

Glioblastoma treatment strategies aim to manage symptoms, slow tumor growth, and prolong survival. Standard treatment options include:

a) Surgery: Surgical removal of the tumor, whenever feasible, is often the initial step in treatment. However, complete removal may be challenging due to the tumor’s infiltrative nature.

b) Radiation Therapy: High-energy rays are used to target the remaining tumor cells post-surgery. It reduces the risk of recurrence and manages tumor-related symptoms.

c) Chemotherapy: Powerful drugs that kill or slow the growth of cancer cells are administered orally or intravenously. Chemotherapy may be given concurrently with radiation therapy or alone, depending on the individual’s health condition.

d) Targeted Therapies: Innovative treatments, such as anti-angiogenic drugs or genome-targeted therapies, are being investigated or are approved to treat via disrupting the specific tumor-promoting mechanisms in glioblastoma.

e) Clinical Trials: Participation in clinical trials may provide access to experimental therapies and novel treatment approaches.

Glioblastoma represents a daunting challenge in the realm of brain tumors, presenting with aggressive advancement and limited treatment options. Glioblastomas almost universally recur following initial treatment and such recurrent tumors have even more limited treatment options. Recognizing the early warning signs and seeking prompt medical attention is crucial for improving prognosis and enhancing the quality of life for those affected by glioblastoma. Continued research and the development of innovative treatment strategies offer hope for a brighter future in tackling this formidable disease.
