No, glioblastoma (GBM) is generally not considered curable, even if caught early, as it's a highly aggressive cancer that almost always recurs, with treatment aiming to control the tumor and improve quality of life, though early detection and aggressive treatment can improve survival times. While complete cures are extremely rare, some factors like good initial health (Karnofsky score), specific genetic markers (MGMT methylation), and total surgical removal offer better prognoses and longer survival, with ongoing research focused on finding a cure.
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.
Early diagnosis within 2 weeks and surgical interventions within 3 weeks from the symptom onset are associated with prolonged patient survival. Early GBM treatment will benefit patients with GBM.
Exposure to ionizing radiation therapy—especially to the head or neck—has been identified as a glioblastoma risk factor. Some studies have linked occupational exposure to certain chemicals to an increased risk for brain tumors, but other studies have found no such correlation.
Prognosis is poor: death occurs within 12–18 months from diagnosis. There is however a small percentage of Patients affected by glioblastoma who survive 3 years or longer. There are some exceptional cases when people have survived decades after surgical removal of a glioblastoma without any recurrence.
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.
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.
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.
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).
Who gets glioblastomas? Glioblastomas tend to develop in men more often than in women, in people 50 or older, and in Caucasians.
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).
Common symptoms include: Headaches: often one of the first signs of glioblastoma. They may worsen over time, become more frequent and resist over-the-counter pain medicine. Headaches can be accompanied by nausea, vomiting, or worsening pain when lying down, bending over, or straining.
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.
What's the treatment for GBM? The standard of treatment for a GBM is surgery, followed by daily radiation and oral chemotherapy for six and a half weeks, then a six-month regimen of oral chemotherapy given five days a month.
Glioblastoma often grows into the healthy brain tissue, so it might not be possible to remove all of the cancer cells. Most people have other treatments after surgery to kill the cancer cells that are left.
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. The figures above are given in 1 and 5-year intervals just because doctors use these intervals for research and measuring.
Factors that can increase the risk of glioblastoma include:
In 2002, human cytomegalovirus (HCMV) was detected in 100% of glioblastoma tumours. Although its role in cancer remains debated, and HCMV is not classified as an oncovirus, numerous studies have reported high viral prevalence in glioblastoma.
Brain tumor patients should avoid:
Researchers at the University of Michigan in Ann Arbor, Michigan, U.S., have discovered that changes to the diet could be a new avenue to slow down the rapid growth of glioblastoma. Glioblastoma is the most aggressive and deadliest form of brain cancer, affecting 0.59 to 5 per 100,000 individuals worldwide.
Cell phones do not cause cancer, no matter how long they are used, because they communicate using radio waves. Radio waves simply don't have enough energy per photon to ionize atoms.
Based on data obtained between 2011 through 2015, about 2-3 people per 100,000 are diagnosed with glioblastoma each year in the United States and Europe. Glioblastoma cases appear to be increasing globally, while survival rates remain poor.
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.
Death of Singer Tom Parker Highlights the Danger of Glioblastoma. The death of Tom Parker, a member of the British boy band, The Wanted, was announced yesterday, less than two years after he revealed his diagnosis of an inoperable, stage four glioblastoma.
