About 200,000 people die each year from a glioblastoma in the world, including nearly 15,000 in Europe and 9,000 in the United States.
Although the average life expectancy after diagnosis is 14 to 16 months, approximately 1% of patients survive at least 10 years. Currently, the longest anyone has survived a glioblastoma is more than 20 years and counting.
Known medically as glioblastoma multiforme (GBM), the cancer has also claimed the lives of senators Ted Kennedy and John McCain, actors Robert Forster and Tim Conway, as well as Beau Biden.
Glioblastoma Facts & Figures
It is estimated that more than 10,000 individuals in the United States will succumb to glioblastoma every year. The five-year survival rate for glioblastoma patients is only 6.9 percent, and the average length of survival for glioblastoma patients is estimated to be only 8 months.
I know many glioblastoma (level 4) survivors that have beaten the odds – one is over 16 years out clean- another is almost 25 years out.
GBM is a devastating brain cancer that can result in death in six months or less, if untreated; hence, it is imperative to seek expert neuro-oncological and neurosurgical care immediately, as this can impact overall survival.
Surgery, radiation and chemotherapy can help slow the tumor's growth, but the disease remains incurable.
For instance, glioblastoma, the most common form of brain cancer in adults, has a five year survival rate of 4.6%.
A case report described a single patient with 20-year survival after glioblastoma diagnosis [75]. The 45-year-old Caucasian man was diagnosed with glioblastoma at the age of 25 years. After initial treatment (surgery and radiation) there were two tumor recurrences, two and 20 years after initial diagnosis.
People who have undergone radiation therapy as a treatment for leukemia, fungal infections of the scalp or previous cancers of the brain have an elevated risk of developing glioblastoma. Other risk factors include being male, being 50 years of age or older and having chromosomal abnormalities on chromosome 10 or 17.
If you have a glioblastoma headache, you will likely start experiencing pain shortly after waking up. The pain is persistent and tends to get worse whenever you cough, change positions or exercise. You may also experience throbbing—although this depends on where the tumor is located—as well as vomiting.
Glioblastoma multiforme (GBM) is a fast-growing, aggressive brain cancer. In the final stages of the disease, end-of-life signs may become more apparent. These can include decreased appetite, withdrawal, changes in behavior, increased fatigue, difficulty speaking or swallowing, and labored breathing.
Glioblastoma multiforme (GBM) is the most common and aggressive primary intracranial tumor. Despite modern therapies, it is still fatal with tremendously poor prognosis with a median survival of 14 months.
According to the National Brain Tumor Society, the average survival of glioblastoma patients is eight months after diagnosis; only 6.8% are alive after five years. Most gliomas are sporadic and seem to have no clear genetic cause. Only about 5% of gliomas are familial, afflicting two or more members of the same family.
Contributing factors may include an increase in diagnosis consequent to increasing ease of access to neuroimaging, an aging population, ionizing radiation, radiofrequency electromagnetic fields (RF-EMF) and air pollution, among others [11-18].
Glioblastoma is the most lethal primary central nervous system cancer. Part of the reason the tumor is so deadly is because it is hard to treat. The tumor itself is invasive and aggressive – it develops tentacles that invade other areas. This makes it hard to completely remove with surgery.
A major obstacle to successfully treating glioblastoma is that these tumor cells multiply so quickly and are so invasive that, even before the main tumor mass can be removed, malignant cells have already invaded other parts of the brain.
In the final stages of the disease, the patient's body will begin to shut down. Patients may lose the ability to speak, eat, and move. They may also suffer from seizures, hallucinations, or changes in breathing pattern. The skin may take on a bluish tint, and the patient may become increasingly lethargic.
Headaches: These are often the first symptoms of glioblastoma. Brain tumor headaches can differ from normal headaches. They typically become more frequent over time and may not respond to over-the-counter pain medicine.
Although glioblastoma multiforme (GBM) is the most common primary brain tumour, it has an incidence of only 6.8 per 100,000. As a result, most general practitioners (GPs) will care for very few patients with this condition, and low-grade tumours are even less common.
Glioblastoma survival rate
The average glioblastoma survival time is 12-18 months – only 25% of patients survive more than one year, and only 5% of patients survive more than five years.
Part of the reason why glioblastomas are so deadly is that they arise from a type of brain cell called astrocytes. These cells are shaped like a star, so when the tumors form they develop tentacles, which makes them difficult to remove surgically. Additionally, the tumors advance rapidly.
There's no cure for glioblastoma, which is also known as glioblastoma multiforme. Treatments might slow cancer growth and reduce symptoms.
Columbia researchers led a clinical trial of selinexor, the first of a new class of anti-cancer drugs, which was able to shrink tumors in almost a third of patients with recurrent glioblastoma. The results of the international phase 2 trial were published in the January 10, 2022, issue of Clinical Cancer Research.
Introduction. Glioblastoma multiforme is the most aggressive type of primary brain tumors, but there is a small percentage of patients who have a long-term survival and some exceptional cases who survive decades after surgical removal of tumor.
