Overall survival rates were 83 and 69% for patients with methylated tumors and 56 and 38% for those with unmethylated tumors at 2 and 3 years, respectively. Radiation Therapy Oncology Group (RTOG) Grade 2 and grade 3 mental status deterioration were detected in 31 and 25% of patients, respectively.
How long can you live after brain radiation?
The median follow-up of patients was 7 months, with a minimum of 2 months and a maximum of 34 months. At the end of the study period, 25 deaths were registered (71%). The median survival with brain metastases was 4.43 months, ranging from 0.73 months to 78.53 months.
What are the long term effects of whole brain radiation?
Radiation to the brain can also have side effects that show up later – usually from 6 months to many years after treatment ends. These delayed effects can include serious problems such as memory loss, stroke-like symptoms, and poor brain function.
How many times can you have radiotherapy on the brain?
You usually have one treatment (fraction) a day, from Monday to Friday, for between 3 to 6 weeks. This means that you have between 15 and 30 treatments of radiotherapy in total. You might have radiotherapy to help with symptoms or slow down the growth of your tumour.
How dangerous is brain radiation?
Radiation is a powerful weapon against cancer cells, but sometimes it kills healthy brain tissue as well—a severe side effect called radiation necrosis. Necrosis (a late effect of high doses of radiation) can cause headaches, seizures, or even death in a small number of cases.
Does radiation work on brain cancer?
1. Radiation kills cancer. There’s a reason radiation therapy is one of the main ways doctors treat metastatic brain tumors today — it works. Radiation therapy is effective in destroying cancer cells.
Is whole brain radiation successful?
Lim says radiation therapy has been shown to be as effective as surgery in several studies, and it could even reduce your chances of a tumor recurrence (the tumor coming back). As radiation therapies become more advanced, people who undergo treatments for brain metastases are living longer than ever before.
Does radiation to the brain cause dementia?
Dementia can develop as early as three months after radiotherapy to the brain. It can also occur 48 months or longer after completion of radiation therapy. Symptoms of dementia (such as memory loss) can also occur after surgery to remove a brain tumor.

What happens to brain tumor after radiation?
Can a brain tumor be treated with radiation therapy?
You will not see or feel the radiation. Stereotactic radiosurgery can be used in some tumors and is even more precise. It targets a small area in your brain with high doses of radiation and delivers lower doses of radiation to the normal tissue around it.
Which is worse brain radiation or brain radiosurgery?
Three months later, 92 percent of patients who got both treatments had cognitive decline versus 64 percent of those given just radiosurgery. “The negative effects far outweigh any benefits” of the combo treatment, Brown said.
Are there any side effects of whole brain radiation therapy?
The side effects of whole brain radiation therapy may not be noticeable until a few weeks after treatment begins. Radiation to the brain can cause these short-term side effects: Headaches
How does stereotactic radiosurgery work on brain cancer?
The beam passes through your body and destroys cancer cells in its path. You will not see or feel the radiation. Stereotactic radiosurgery can be used in some tumors and is even more precise. It targets a small area in your brain with high doses of radiation and delivers lower doses of radiation to the normal tissue around it.
