Brain Cancer Statistics

A brain cancer diagnosis can be devastating to patients and their families. The statistics below are a powerful reminder of why Tocagen is seeking to provide meaningful increases in survival.

  • Gliomas include all tumors arising from the supportive tissue of the brain, and account for about 80 percent of all malignant brain tumors.
  • About 14,000 new cases of high grade gliomas (HGG) are expected to be diagnosed in the United States in 2016. HGG tumors include glioblastoma multiforme (GBM) and anaplastic astrocytoma (AA).
  • GBM accounts for about half of all primary brain and central nervous system (CNS) cancers.
  • The 1, 2 and 5-year survival rate for patients with GBM is about 37 percent, 15 percent, and 5 percent respectively, making these tumors the two most fatal forms of all primary brain and central nervous system cancers.

Tocagen is developing an investigational therapy to treat GBM and AA and is currently recruiting patients into its Phase 2/3 clinical trial, Toca 5. Learn about the Toca 5 trial.
