Glioblastoma (GBM) survival trends show slow, incremental improvements, with median survival around 12-23 months, but remain poor (under 10% 5-year survival). Key factors boosting survival include younger age, extensive tumor removal, standard trimodal therapy (surgery, radiation, temozolomide), and specific tumor genetics (like IDH-mutant or MGMT-methylated). While long-term survival is rare, recent studies indicate modest upward trends in 2-year survival, linked to better management and evolving treatments.
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.
The average life expectancy for glioblastoma patients who undergo treatment is 12-15 months and only four months for those who do not receive treatment. Nearly 28% of brain and central nervous system (CNS) tumors are malignant, and nearly 50% of those malignant tumors are Glioblastoma.
Glioblastoma is one of the most aggressive and common brain tumors, with a median survival of 10-15 months.
There are some exceptional cases when people have survived decades after surgical removal of a glioblastoma without any recurrence. We report a case of a 44 year-old man operated for a glioblastoma. 22 years after surgery the patient has no recurrence of the tumor.
As the tumor expands, it can cause increased pressure within the skull, leading to headaches, nausea, and vomiting. Depending on the exact location, patients may experience neurological deficits such as weakness, speech difficulties, vision changes, or seizures, which are often the presenting symptom.
In October 2020, at the age of 32, Parker was diagnosed with an inoperable brain tumour. The Wanted reunited in September 2021, but after a sudden deterioration in his condition, Parker died of complications from glioblastoma on 30 March 2022, at the age of 33.
In most cases, the exact underlying cause of glioblastoma multiforme is unknown. In rare cases, it can occur in people with certain genetic syndromes, such as neurofibromatosis type 1, Turcot syndrome and Li Fraumeni syndrome.
Without treatment, glioblastoma progresses very rapidly, leading to significant symptoms in a matter of weeks to a few months.
Glioblastoma patients with blood vitamin D levels greater than 30 ng/mL prior to initiation of chemotherapy and radiation have longer overall survival [65], and those who reported vitamin D use after diagnosis of glioblastoma have been reported to have a survival advantage [45].
There are no studies with conclusive evidence to say that stress causes glioblastoma or any other type of glioma. However, we do know that overwhelming amounts of stress can reduce immune system function (the part of your body that fights off disease and tumors).
For glioblastoma, radiation is still the most effective therapy. But radiation exposure also is the only known risk factor for its development, and could perhaps also drive recurrence.
There are several factors that are believed to increase the risk of glioblastoma, including: Exposure to pesticides, petroleum, synthetic rubber, vinyl chloride and other chemicals. Genetic conditions, such as neurofibromatosis, Li-Fraumeni syndrome and Turcot syndrome that are known to cause tumors.
Glioblastomas are highly aggressive, which means the tumors typically grow and spread very rapidly. Glioblastomas almost always occur sporadically in people who have no family history of brain tumors. As such, scientific evidence suggests that this malignancy is not hereditary in the vast majority of cases.
In 2024, Carmen celebrated 20-years being cancer free from glioblastoma. Overall, glioblastoma has a five-year survival rate less than 7%. Carmen Rice is recognized as the longest living glioblastoma (GBM) cancer survivor.
There is currently no cure for glioblastoma. The median length of survival after a diagnosis is 15-18 months, while the disease's five-year survival rate is around 10%. Though all glioblastomas recur, initial treatments may keep the tumor controlled for months or even years.
Glioblastoma signs of decline
Because glioblastoma is difficult to treat, the patient's symptoms will eventually get worse. He or she may be sleepy and spend more time sleeping, and the patient may have headaches and nausea. It'll get harder to move and speak, and the patient may have problems swallowing or seeing.
Patients living with glioblastoma are already at an increased risk of anxiety and depression due to the emotional burden of their diagnosis and the impact of the tumor itself. Keppra rage can exacerbate these conditions, making emotional management more difficult.
How to support someone with a brain tumour
1. Myth: Cell phones cause glioblastoma. Fact: To date, there is no established link that cell phones cause glioblastoma. Several different studies have failed to find clear evidence of a link between cell phone use and brain cancer.
Who gets glioblastomas? Glioblastomas tend to develop in men more often than in women, in people 50 or older, and in Caucasians.
It has been suggested that COVID-19 infections are associated with a unique brain predisposition to thrombosis caused by cytokine storms (9), which is correlated with faster GBM development. Poor prognosis is associated with tumor thrombus in GBM (10).
Grammy-winning singer @michaelbolton was first diagnosed with an aggressive form of brain cancer called glioblastoma in 2023. His two daughters, Isa and Taryn Bolton, share how they've cared for him following his diagnosis, and how they're navigating the ups and downs of his health journey.
Treatment includes surgery, radiation, and chemotherapy, but even after treatment, GBM almost always grows back in about 9-10 months. This high recurrence rate is due to the invasive nature of the tumor, which infiltrates surrounding brain tissue, making it difficult to remove completely.
Some of the first signs of a brain tumor may include:
