Glioblastoma multiforme (GBM) is the most common and aggressive primary brain tumor in adults. It arises from astrocytes, the star-shaped glial cells in the brain and spinal cord. GBM is characterized by rapid growth and a tendency to infiltrate surrounding brain tissue, making it particularly challenging to treat.
Genetic and molecular factors
Research has identified several genetic mutations associated with glioblastoma:
- IDH mutations: Mutations in the isocitrate dehydrogenase (IDH) genes are found in a subset of GBM cases and are associated with a better prognosis.
- EGFR amplification: Overexpression of the epidermal growth factor receptor (EGFR) gene promotes tumor growth.
- TERT promoter mutations: These mutations lead to increased telomerase activity, allowing cancer cells to replicate indefinitely.
Additionally, epigenetic changes, such as DNA methylation of the MGMT gene promoter, can influence the tumor's response to therapy.

Environmental and lifestyle factors
While the exact environmental causes of GBM are not fully understood, some studies suggest potential links:
- Ionizing radiation: Exposure to high doses of ionizing radiation is a well-established risk factor for brain tumors.
- Occupational exposures: Certain occupations involving exposure to chemicals like pesticides and solvents may have an increased risk.
- Electromagnetic fields: The association between mobile phone use and GBM risk remains inconclusive, with studies yielding mixed results.
It's important to note that most GBM cases occur sporadically, without identifiable environmental triggers.
The role of cancer stem cells
Glioblastoma contains a subpopulation of cells known as cancer stem cells (CSCs). These cells have the ability to self-renew and differentiate, contributing to tumor growth and resistance to conventional therapies. Targeting CSCs is a focus of ongoing research, aiming to develop treatments that can prevent tumor recurrence.
Advancements in research
Recent studies have provided deeper insights into GBM:
- Tumor microenvironment: Research has highlighted the importance of the tumor microenvironment, including factors like hypoxia and immune cell infiltration, in GBM progression.
- Immunotherapy: Emerging treatments aim to harness the immune system to recognize and attack GBM cells, with some early successes in clinical trials.
- Genomic profiling: Advanced sequencing techniques are enabling personalized treatment approaches based on the tumor's genetic makeup.
These advancements offer hope for more effective therapies in the future.
Considering future options: cryopreservation
Facing a diagnosis of glioblastoma can be overwhelming, especially when treatment options are limited. In such cases, exploring future-oriented possibilities becomes essential.
At Tomorrow.bio, we offer human cryopreservation—a process of preserving individuals at low temperatures after legal death, with the hope that future medical advancements may allow for revival and treatment. While not a cure, it represents an opportunity to bridge today's limitations and tomorrow's possibilities.
We understand the emotional weight of a terminal diagnosis. Our team is here to provide information and support, helping you make informed decisions about your future.
