The role of radiation treatment in craniopharyngioma

The long natural course of craniopharyngioma and short-term follow-up period in many reports make comparison of various treatment results difficult. Some patients may enjoy virtually symptom-free lives despite known recurrence. Some patients with recurrence may have a good response to retreatment. Such unpredictable behavior and treatment responses have led to considerable disparity in clinical reports concerning the best treatment method. Treatments using surgery alone and/or low dose postoperative radiation treatment could prolong survival time, but may not prevent recurrence leading to ultimate failure. High dose postoperative radiotherapy following radical surgery should be an ideal approach in dealing with this tumor.
