Overview
Radiotherapy and chemotherapy are recommended among all patients who develop gliomatosis cerebri. Temozolomide and PCV 3 combination chemotherapy are the preferred drugs for the treatment of high-grade and low-grade gliomatosis cerebri, respectivel Supportive therapy for gliomatosis cerebri includes anticonvulsants and corticosteroids.
Medical Therapy
The medical therapy of gliomatosis cerebri includes:
1. Radiotherapy
- Post-operative radiotherapy is recommended among all patients who develop gliomatosis cerebri.[1]
- Radiotherapy may not cure the cancer but can control the tumor, delay recurrence, and increase survival.
- Radiation therapy is associated with temporary improvement of clinical symptoms.[2]
- External beam radiation therapy is preferred to whole brain radiotherapy.[3]
- The median dose of radiation is 60 Gy (range: 50-72 Gy).[1]
2. Chemotherapy
- Chemotherapy is indicated as adjuvant therapy for gliomatosis cerebri.
- Temozolomide (Temodar) is the preferred drug for the treatment of high-grade gliomatosis cerebri.[4][5]
- PCV 3 combination chemotherapy is the preferred drug regimen for slow growing, low-grade gliomatosis cerebri.[6]
- 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.[7]
- Other chemotherapeutic drugs that may be used for the treatment of gliomatosis cerebri include:[8][9][10]
3. Supportive treatment
- Supportive therapy for gliomatosis cerebri includes anticonvulsants and corticosteroids, which focuses on relieving symptoms and improving the patient’s neurologic function.[2]
- 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 headache or drowsiness.
