Management of craniopharyngiomas: Role of conservative strategies

Abstract

Craniopharyngiomas are uncommon tumors and their management remains controversial. Despite gross total resection, recurrences can occur in 15-43% during long-term follow-up of more than 10 years. Furthermore, radical surgery can be associated with complications associated with hypothalamic damage, which can lead to a poor quality-of-life. Limited surgery followed by adjuvant radiotherapy (RT) can provide excellent long-term tumor control with minimum complications and good functional outcome. RT can however, produce insidious onset of hypopituitarism and vasculopathy. Secondary malignancies are a rare complication of RT. Modern radiation techniques and intracystic radiation can reduce these complications. Intracystic radiation is highly effective for cystic craniopharyngiomas. Intracystic bleomycin (ICB) and interferon alpha (IFN) are rarely curative, but can produce long lasting control of tumor cysts and this is very useful in very young children who may not tolerate radical surgery or RT. IFN has fewer toxicity issues compared to ICB.

Key words

Bleomycin - craniopharyngioma - interferon alpha - management - radiotherapy
