5–Year relative survival rate: Age 20–44, 76%. Age 45–54, 67%. Age 55–64, 45%. [7] [8] Procarbazine, lomustine and vincristine have been used since May 1975. For 48 years, new therapeutic options have been regularly tested as part of therapy studies to improve the treatment of anaplastic oligodendroglioma. [9]
A 2005 study analyzed survival based on chromosomal deletions and the effects of radiation or chemotherapy as treatment, with the following results (both low-grade and anaplastic oligodendrogliomas): 1p/19q deletion with radiation = 121 months (mean), 1p/19q deletion with chemotherapy = over 160 months (mean not yet reached), no 1p/19q deletion ...
[3] [2] Grades III and grade IV are considered malignant astrocytomas. Anaplastic astrocytomas are considered by the WHO to be a grade III astrocytoma and Glioblastoma is a grade IV both are referred to high-grade glial tumors. [2] Ependymal tumors are another glial tumor type of the central nervous system.

Several types of cancer are associated with high survival rates, including breast, prostate, testicular and colon cancer. Brain and pancreatic cancers have much lower median survival rates which have not improved as dramatically over the last forty years. [4] Indeed, pancreatic cancer has one of the worst survival rates of all cancers.
In the United States during 2013–2017, the age-adjusted mortality rate for all types of cancer was 189.5/100,000 for males, and 135.7/100,000 for females. [1] Below is an incomplete list of age-adjusted mortality rates for different types of cancer in the United States from the Surveillance, Epidemiology, and End Results program.
Oligoastrocytomas are a subset of brain tumors that present with an appearance of mixed glial cell origin, astrocytoma and oligodendroglioma. [1] However, the term "Oligoastrocytoma" is now considered obsolete by the National Comprehensive Cancer Network [2] stating "the term should no longer be used as such morphologically ambiguous tumors can be reliably resolved into astrocytomas and ...
