@entity7667 ( @entity7667 ) are rare central @entity5 . @entity1 and treatment factors associated with outcome are poorly defined and limited to small retrospective case series and single case reports. Using the Surveillance, Epidemiology, and End Results (SEER) @entity5 registry, we investigated potential clinicopathological factors that can affect outcome in @entity1 with @entity7667 . @entity1 with @entity7667 diagnosed between 1973 and 2007 were identified from the SEER database. Kaplan-Meier survival analysis and Cox models were used to examine the effect of variables on overall survival. The variables analysed included @entity1 age at diagnosis, gender, race, @entity5 location, uni-focal or multi-focal @entity5 , surgical resection and the use of adjuvant radiotherapy. Fifty-eight @entity1 were identified, with a median age at diagnosis of 25.5 years. Ninety-three percent of @entity1 underwent surgery and 36% received adjuvant radiotherapy. The median overall survival was 28.5 months. The most common @entity5 site was the temporal lobe (27%). Univariate and multivariate analysis identified surgery and uni-focal disease as important predictors of overall survival. Adjuvant radiotherapy did not influence overall survival. This study represents the largest analysis of @entity7667 to date. Furthermore it also emphasises the role of national @entity5 databases for furthering our understanding of rare @entity1313 and determining management options.
