Oligoastrocytomas are a subset of brain tumors that present with an appearance of mixed glial cell origin, astrocytoma and oligodendroglioma.[1] These types of glial cells that become cancerous are involved with insulating and regulating the activity of neuron cells in the central nervous system. Often called a "mixed glioma", about 2.3% of all reported brain tumors are diagnosed as oligoastrocytoma.[citation needed] The median age of diagnosis is 42 years of age.[citation needed] Oligoastrocytomas, like astrocytomas and oligodendrogliomas, can be divided into low-grade and anaplastic variant, the latter characterized by high cellularity, conspicuous cytologic atypism, mitotic activity and, in some cases, microvascular proliferation and necrosis.
However, lower grades can have less aggressive biology.
These are largely supratentorial tumors of adulthood that favor the frontal and temporal lobes.

Symptoms
There are many possible symptoms of oligodendrogliomas that are similar to other gliomas. These symptoms may include headache, seizure and speech or motor changes.
Diagnosis
A Computed Tomography (CT) or Magnetic Resonance Imaging (MRI) scan is necessary to characterize the anatomy of this tumor as to size, location, and its heter/homogeneity. However, final diagnosis of this tumor, like most tumors, relies on histopathologic examination (biopsy examination).[citation needed]
Treatment
If resected, the surgeon will remove as much of this tumor as possible, without disturbing eloquent regions of the brain (speech/motor cortex) and other critical brain structure. Thereafter, treatment may include chemotherapy and radiation therapy of doses and types ranging based upon the patient's needs. Subsequent MRI examination are often necessary to monitor the resection cavity.
Prognosis
Even after surgery, an oligoastrocytoma will often recur. The treatment for a recurring brain tumor may include surgical resection, chemo and radiation therapy. Survival time of this brain tumor varies - younger age and low-grade initial diagnosis are factors in improved survival time.

- Malignant glioma is the most common intracranial tumor with a dismal prognosis. The radiosensitizing effect of silver nanoparticles (AgNPs) on glioma both in vitro and in vivo had been demonstrated in the previous studies of our group. However, the underlying mechanism is still unclear. Consistent

- Studies with AZD2171-a new anti-angiogenic inhibitor of tyrosine kinases associated with VEGF signaling-have shown great promise for treating glioblastoma. Unfortunately, AZD2171 success is limited by low permeability through the blood-brain barrier. Due to AZD2171's short half-life and high toxicit
