Patterns of Care in Pediatric Craniopharyngioma: Outcomes Following Definitive Radiotherapy.

Background/aim: Few data are available on the utility of definitive radiation therapy (RT) for pediatric craniopharyngioma. This study sought to evaluate practice patterns and patient outcomes using the Surveillance Epidemiology and End Results database from 2004-2014.

Materials And Methods: Overall survival (OS) was compared between five treatment groups, definitive radiation therapy (RT), gross total resection (GTR), subtotal resection (STR), STR+RT, and observation/biopsy only, using Kaplan-Meier analysis and log-rank tests. Multivariate Cox proportional hazards modeling determined variables independently associated with OS.

Results: A total of 373 patients met the study criteria. GTR and definitive RT conferred superior OS than observation/biopsy (p=0.008 and 0.029), but were equivalent to STR+RT (p=0.350 and 0.200). GTR was associated with a higher OS than STR (p=0.027). On multivariate analysis, STR+RT, GTR, and definitive RT were associated with statistically equivalent OS (p=0.990).

Conclusion: Definitive RT for pediatric craniopharyngioma affords similar outcomes to established modalities of therapy such as GTR and STR+RT.
