Overview
If left untreated, patients with oligoastrocytoma may progress to develop seizures, focal neurological deficits, hydrocephalus, brain herniation, intracranial hemorrhage, and ultimately death.[1][2][3] Oligoastrocytomas are slow growing tumors.[4] Common complications associated with oligoastrocytoma include hydrocephalus, intracranial hemorrhage, coma, metastasis, venous thromboembolism, and side effects of chemotherapy and radiation.[2][5][6][1][7][3] Depending on the extent and grade of the tumor at the time of diagnosis, the prognosis of oligoastrocytoma may vary. However, the prognosis is generally regarded as good.[8] The prognosis for patients with oligoastrocytoma is more favorable than that for anaplastic oligoastrocytoma because of the more indolent course and younger age at which most patients are diagnosed.[2] The 1, 5, and 10-year survival rates of patients with oligoastrocytoma are approximately 87%, 56.97%, and 45.80%.[9]
Natural history
- Oligoastrocytomas are slow growing tumors.[4] The tumors may be present for many years before they are diagnosed.[10]
- If left untreated, patients with oligoastrocytoma may progress to develop seizures, focal neurological deficits, hydrocephalus, brain herniation, intracranial hemorrhage, and ultimately death.[1][2][3]
- The mixed gliomas with a 1p/19q loss would behave in an indolent or chemo-responsive fashion as expected of an oligodendroglioma, whereas those without this profile act biologically like astrocytic tumors, i.e. more aggressively and more prone to high grade transformation .[11]
Complications
Common complications associated with oligoastrocytoma include:[2][5][6][1][7][3]
- Hydrocephalus
- Intracranial hemorrhage
- Coma
- Metastasis
- Recurrence
- Venous thromboembolism
- Side effects of chemotherapy
- Side effects of radiotherapy
Prognosis
- Depending on the extent and grade of the tumor at the time of diagnosis, the prognosis of oligoastrocytoma may vary. However, the prognosis is generally regarded as good.[8]
- The prognosis for patients with oligoastrocytoma is more favorable than that for anaplastic oligoastrocytoma because of the more indolent course and younger age at which most patients are diagnosed.[2]
- The 1, 5, and 10-year survival rates of patients with oligoastrocytoma are approximately 87%, 56.97%, and 45.80%.[9]
- Favorable prognostic factors for oligoastrocytoma include:[12][13][5][14][15][1]
- Presence of 1p19q codeletion
- Age at presentation < 40 years
- Lower grade of tumor
- Absence of tumor necrosis
- Seizure as presenting symptom
- Presence of MGMT gene promoter hypermethylation
- Extent of surgical resection
- Good performance status
- Intact neurological function
- Presence of microvascular proliferation and necrosis are poor prognostic factors for oligoastrocytoma.[16]
