Survival rates

A meningioma's outlook depends on its grade, size and location. The grade shows how fast the cells grow and how likely the tumor is to return. Age and overall health also affect long-term survival.

How a meningioma diagnosis can affect life expectancy

Many people live long lives after treatment. Grade 1 meningiomas are benign. They grow slowly and can often be fully removed.

Data shows that 97% of children and young adults and 86% of older adults are alive five years after diagnosis. Ten years after diagnosis, survival remains high — about 80% to 97% depending on age.

Survival rates by tumor grade

WHO Grade Typical behavior and outcomes
Grade 1 Grows slowly and is often cured with surgery; about 90% are alive 5 years after diagnosis.
Grade 2 Grows faster and returns more often; about 80% are alive at 5 years and about 66% at 10 years.
Grade 3 Rare and more aggressive; about 58% of people are alive 5 years after diagnosis, including about 66% of females and 47% of males.

What influences survival

Several factors shape survival with meningioma. Some can be improved with treatment choices, while others depend on the tumor itself. Factors can include:

  • How much tumor is removed. Complete removal gives the best long-term control. If only part can be removed, radiation helps keep it from growing again.
  • If the tumor can't be fully removed. Targeted radiation and regular MRI can control growth and maintain quality of life.
  • Radiation therapy for higher grades. For grade 2 and 3 tumors, radiation after surgery can extend life and lower the chance of recurrence.
  • Tumor location. Tumors near the skull base or optic nerve are harder to remove completely and more likely to return.
  • Tumor biology. Faster growing tumors with higher grades (2 or 3) tend to come back sooner.
  • Tumor site (brain vs. spine). Spinal meningiomas are often grade 1 and have excellent long-term survival after surgery.

Recurrence and follow-up

About 20% to 30% of grade 2 meningiomas and 70% to 80% of grade 3 meningiomas return within 10 years. Regular imaging and full removal lower that risk.

Follow-up imaging is key: MRIs every few months at first, then less often over time. If a tumor comes back, additional surgery or radiation can still provide many good years of life.

What this means for you: Most people with meningioma, especially grade 1, live many years without or after treatment. Higher grade tumors need closer monitoring and sometimes combined treatments. But outcomes continue to improve as surgery and radiation techniques advance.
