Glioblastoma Overview

Glioblastoma, a type of cancer that originates in astrocytes, which are cells that support nerve cells, is known for its rapid growth and invasion of healthy brain or spinal cord tissue. It can occur at any age but is more common in older adults and tends to affect men more frequently. Glioblastoma is the most common and aggressive malignant brain tumor in adults, accounting for approximately 12-15% of all primary intracranial neoplasms. Its fast growth and aggressive nature set it apart from other brain tumors. Recent research has focused on understanding the molecular pathology of glioblastoma and identifying clinically relevant subtypes characterized by specific genetic markers[5]. Innovative treatments, such as tumour-treating fields (TTFields) and immunotherapy, have shown promise in enhancing survival rates.

Unraveling the Causes and Risk Factors of Glioblastoma

The exact causes of glioblastoma are not fully understood, but certain risk factors have been identified. These include exposure to ionizing radiation, a family history of glioblastoma, and certain genetic disorders such as neurofibromatosis and Li-Fraumeni syndrome. Recent research has highlighted the role of radiation and specific genetic syndromes as the primary risk factors for glioblastoma. Understanding these risk factors is crucial in developing effective prevention and treatment strategies.

Glioblastoma: Prevalence, Inheritance, and Latest Research Findings

Glioblastoma, the most common and aggressive malignant brain tumor in adults, accounts for approximately 12-15% of all primary intracranial neoplasms. It is more prevalent in adults aged 45-65 and tends to affect men more frequently. While there is a risk of developing glioblastoma in certain inherited genetic disorders, there is no direct inheritance pattern mentioned. Recent research has focused on understanding the molecular pathology of glioblastoma and identifying clinically relevant subtypes characterized by specific genetic markers. Innovative treatments, such as tumour-treating fields (TTFields) and immunotherapy, have shown promise in enhancing survival rates.
