Overview

The predominant therapy for oligoastrocytoma is surgical resection. Adjunctive chemotherapy and radiation are required. Supportive therapy for oligoastrocytoma includes anticonvulsants and corticosteroids.

Medical Therapy

The medical therapy of oligodendroglioma includes:

Radiotherapy

  • Post-operative radiotherapy is recommended among all patients who develop oligoastrocytoma.[1][2][3]
  • Radiotherapy may not cure the cancer but can control the tumor, delay recurrence, and increase survival.
  • External beam radiation therapy is preferred to whole brain radiotherapy.[3]
  • It may also be given as the main treatment, if surgery is not an option.
  • External beam radiation therapy is usually administered in standard fractions of 1.8–2 grays (Gy) and can reach a total dose in the range of 60 Gy.[4]

Chemotherapy

Supportive treatment

Supportive therapy for oligoastrocytoma includes anticonvulsants and corticosteroids, which focuses on relieving symptoms and improving the patient’s neurologic function. The types of supportive therapy that may be used are:[3]
