Overview
Medical Therapy
The medical therapy of oligodendroglioma includes:
Radiotherapy
- Post-operative radiotherapy is recommended among all patients who develop oligodendroglioma.[1]
- 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.[1]
Chemotherapy
- Chemotherapy is indicated as adjuvant therapy for oligodendroglioma.[1]
- Oligodendroglioma responds better to chemotherapy than astrocytoma of comparable grade.[2]
- Oligodendroglioma is the most chemosensitive of all the glial tumors.[3]
- Symptomatic, aggressive, enlarging, enhancing, and non-anaplastic oligodendrogliomas respond better to chemotherapy.[4]
- Temozolomide (Temodar) is the preferred drug for the treatment of oligodendroglioma.[1]
- PCV 3 combination chemotherapy is the preferred drug regimen for oligodendroglioma.[1]
- CCNU is administered on day 1, procarbazine is administered daily for 14 days beginning on day 8, and vincristine is administered on days 8 and 29 of each 6-week cycle of therapy.[5]
- Other chemotherapeutic drugs that may be used for the treatment of oligodendroglioma include:[6][3]
- If oligodendroglioma is unresponsive to the chemotherapeutic drugs used in earlier treatments or if it recurs, other drugs that may be used include:[6]
Supportive treatment
- Supportive therapy for oligodendroglioma includes anticonvulsants and corticosteroids, which focuses on relieving symptoms and improving the patient’s neurologic function.[1]
- Anticonvulsants are administered to the patients who have a seizure. Phenytoin given concurrently with radiation may have serious skin reactions such as erythema multiforme and Stevens-Johnson syndrome.
- Corticosteroids, usually dexamethasone given 4-10 mg every 4-6 h, can reduce peritumoral edema, diminish mass effect, and lower intracranial pressure with a decrease in symptoms (headache or drowsiness).
