Modern radiotherapy approaches in the management of craniopharyngiomas.

An audit of treatment regimens at presentation, recurrence and survival rates spanning 37 years were reviewed for children and adults with craniopharyngioma treated at The Prince of Wales or the Sydney Children's hospitals. Eligibility criteria stipulated all patients (n=41) received radiotherapy as part of their treatment course. The primary end point for evaluation was the incidence of radiological progression post-radiotherapy, and secondary end-points were the symptomatic and hormonal status post-radiotherapy. There were 12 paediatric patients (age, <16 years) and 29 adults (age range, 16-80 years). Of the 41 patients, 39 had a suprasellar tumour component, and 38 had radiologically persistent disease post-surgery. Four patients were treated by radiosurgery (median volume treated, 3.5 cm(3)); four patients progressed post-radiotherapy, of whom two were salvaged by further radiotherapy, one succumbed to progressive local disease, and one had a small intrasellar recurrence surgically resected. Progression-free survival (95.12%) was followed for up to 23 years. Thus, subtotal resection and the modern radiotherapy approach is likely to provide excellent patient and disease outcomes.
