Other factors which influence survival include age (younger the better) and performance status (ability to perform tasks of daily living). Due to the infiltrative nature of these tumors, recurrences are relatively common. Depending on the patient, radiation or chemotherapy after surgery is an option. Individuals with grade 2 astrocytoma have a 5-year survival rate of about 34% without treatment and about 70% with radiation therapy. The median survival time is 4 years.

avoided. The extremely infiltrative nature of this tumor makes complete surgical removal impossible. Although radiotherapy rarely cures glioblastoma, studies show that it doubles the median survival of patients, compared to supportive care alone. The prognosis is worst for these grade 4 gliomas. Few patients survive beyond 3 years. Individuals with grade 4 astrocytoma have a median survival time of 17 weeks without treatment, 30 weeks with radiation, and 37 weeks with surgical removal of most of the tumor followed by radiation therapy. Long-term survival (at least five years) falls well under 3%.

patient's brain are taken from many different directions. These are then combined by a computer, producing a cross-sectional image of the brain. For an MRI, the patient relaxes in a tunnel-like instrument while the brain is subjected to changes of magnetic field. An image is produced based on the behavior of the brain's water molecules in response to the magnetic fields. A special dye may be injected into a vein before these scans to provide contrast and make tumors easier to identify.

surgery. Grading of the tumor sample is a method of classification that helps the doctor to determine the severity of the astrocytoma and to decide on the best treatment options.

is commonly used for astrocytoma. Established in 1993 in an effort to eliminate confusion regarding diagnoses, the WHO system established a four-tiered histologic grading guideline for astrocytomas that assigns a grade from 1 to 4, with 1 being the least aggressive and 4 being the most aggressive.

Homozygous deletion of CDKN2A/B is the main feature of high grade astrocytoma. In addition, a genome-wide pattern of DNA copy-number alterations (CNAs) has been uncovered, which is correlated with a patient's survival and response to treatment. This pattern identifies among lower-grade astrocytoma

People can develop astrocytomas at any age. The low-grade type is more often found in children or young adults, while the high-grade type is more prevalent in adults. Astrocytomas in the base of the brain are more common in young people and account for roughly 75% of neuroepithelial tumors.

For low-grade astrocytomas, removal of the tumor generally allows functional survival for many years. In some reports, the 5-year survival has been over 90% with well-resected tumors. Indeed, broad intervention of low-grade conditions is a contested matter. In particular,
