Overview

If left untreated, patients with oligodendroglioma may progress to develop seizures, focal neurological deficits, hydrocephalus, brain herniation, intracranial hemorrhage, and ultimately death.[1] Common complications associated with oligodendroglioma include hydrocephalus, intracranial hemorrhage, coma, bone marrow metastasis, recurrence, venous thromboembolism, parkinsonism, and side effects of chemotherapy and radiotherapy.[2][3][4][5][6][7][8] Depending on the extent and grade of the tumor at the time of diagnosis, the prognosis of oligodendroglioma may vary. However, the prognosis is generally regarded as good. The median survival time for oligodendroglioma is 11.6 years for grade II and 3.5 years for grade III.[9]

Natural history

  • Oligoastrocytomas are slow growing tumors.[10] The tumors may be present for many years before they are diagnosed.[11]
  • If left untreated, patients with oligoastrocytoma may progress to develop seizures, focal neurological deficits, hydrocephalus, brain herniation, intracranial hemorrhage, and ultimately death.[12]
  • 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 .[13]

Complications

Common complications associated with oligoastrocytoma include:[14][15][16][12][17][18]

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.[19]
  • 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.[14]
  • The 1, 5, and 10-year survival rates of patients with oligoastrocytoma are approximately 87%, 56.97%, and 45.80%.[20]
  • Favorable prognostic factors for oligoastrocytoma include:[21][22][15][23][24][12]
  • Presence of microvascular proliferation and necrosis are poor prognostic factors for oligoastrocytoma.[25]
