Statistics

Incidence of Brain Tumors:

Estimated number of people living with a diagnosis of primary brain and central nervous system (CNS) tumor in the US in 2000:

359,000

1

Total new cases of primary brain/CNS tumors (malignant and non-malignant) expected in 2005 in the US: 43,800 1
Total estimated new cases of primary malignant brain /CNS tumors to be diagnosed in 2005 in the US: 18,500 3
Estimated number of deaths attributable to primary malignant brain/CNS tumors in the US in 2005: 12,760 3

The expected incidence of 43,800 new cases is based on an incidence rate of 14.8 per 100,000 people1, and a 2005 US population of 287,716,000.2

Brain tumors are:

Average lifetime risk:4

Observed average relative survival rates for patients diagnosed over the period of 1973-2002 with a primary malignant brain/CNS tumor vs. glioblastoma multiforme, one of the most common primary brain tumors:1

Brain/CNS Tumors Glioblastoma Multiforme
One-year survival rate 51.5% 29.3%
Two-year survival rate 37.3% 8.7%
Five-year survival rate 29.1% 3.3%
Ten-year survival rate 25.3% 2.3%

5-Year survival rate by age for brain & other nervous system cancers5

<45 years 62.5%
45-54 years 25.8%
55-64 years 13.0%
65-74 years 7.0%
+75 years 3.9%

Distribution of all primary brain and CNS gliomas by histology1
(Gliomas account for 40% of all primary brain / CNS tumors and for 78% of malignant brain tumors; astrocytomas and glioblastomas account for 75% of all gliomas)
