American Brain Tumor Association presenterer fakta og statistikk for hjernesvulst i USA per desember 2015.
Brain tumors are the:
- most common cancer among those age 0-19 (leukemia is the second).
- second leading cause of cancer-related deaths in children (males and females) under age 20 (leukemia is the first).
Brain Tumor Statistics:
- Nearly 78,000 new cases of primary brain tumors are expected to be diagnosed this year. This figure includes nearly 25,000 primary malignant and 53,000 non-malignant brain tumors.
- It is estimated that more than 4,600 individuals between the ages of 0-19 will be diagnosed with a primary brain tumor this year.
- Malignant brain tumors are the most common cause of cancer-related deaths in adolescents and young adults aged 15-39 and the most common cancer occurring among 15-19 year olds.
- There are nearly 700,000 people in the U.S. living with a primary brain and central nervous system tumor.
- This year, nearly 17,000 people will lose their battle with a primary malignant and central nervous system brain tumor.
- There are more than 100 histologically distinct types of primary brain and central nervous system tumors.
- Survival after diagnosis with a primary brain tumor varies significantly by age, histology, molecular markers and tumor behavior.
- The median age at diagnosis for all primary brain tumors is 59 years.
- Meningiomas represent 36.4% of all primary brain tumors, making them the most common primary brain tumor. There will be an estimated 24,880 new cases in 2016.
- Gliomas, a broad term which includes all tumors arising from the gluey or supportive tissue of the brain, represent 27% of all brain tumors and 80% of all malignant tumors.
- Glioblastomas represent 15.1% of all primary brain tumors, and 55.1% of all gliomas.
- Glioblastoma has the highest number of cases of all malignant tumors, with an estimated 12,120 new cases predicted in 2016.
- Astrocytomas, including glioblastoma, represent approximately 75% of all gliomas.
- Nerve sheath tumors (such as acoustic neuromas) represent about 8% of all primary brain tumors.
- Pituitary tumors represent 15.5% of all primary brain tumors. There will be an estimated 11,700 new cases of pituitary tumors in 2016.
- Lymphomas represent 2% of all primary brain tumors.
- Oligodendrogliomas represent nearly 2% of all primary brain tumors.
- Medulloblastomas/embryonal/primitive tumors represent 1% of all primary brain tumors.
- The majority of primary tumors (36.4%) are located within the meninges.
