*15.3.2. Radiation*

Radiotherapy is considered as a treatment option for OPG but at a cost of long term complications of neurocognitive dysfunction and visual disturbances [45]. Radiation may therefore be useful for an adjuvant treatment in the case of chemotherapy refractory tumors. Prognosis depends upon the age of the patient and location of the tumour. Young age and tumour located in optic pathway and hypothalamus are considered as poor prognostic factors.
