Radiotherapy for the treatment of recurrent craniopharyngioma.

Twenty-five patients with craniopharyngioma received radiotherapy at the time of recurrence. The 10-year progression free survival and survival from the time of recurrence were 72% and 77% respectively. Nineteen patients underwent surgery prior to radiotherapy (6 partial excision, 4 decompression and 9 cyst aspiration). The extent of resection at the time of recurrence did not influence the outcome. Apart from pituitary failure there was no serious morbidity associated with this approach. The results of radiotherapy at recurrence are similar to those of conservative surgery and radiotherapy at the time of presentation. It suggests that radiotherapy remains an effective treatment modality at the time of recurrence of craniopharyngioma and it may therefore be delayed in situations where immediate radiation is not advisable. However, the high recurrence rate in incompletely excised craniopharyngioma, together with the potential risk of additional morbidity and mortality from undiagnosed progressive tumour and salvage surgery, would argue for a policy of radiotherapy as part of the initial treatment of incompletely excised craniopharyngioma.
