Receiver operating characteristic curve analysis of SEER medulloblastoma and primitive neuroectodermal tumor (PNET) outcome data: identification and optimization of predictive models.

Purpose: This study used receiver operating characteristic curves to analyze Surveillance, Epidemiology and End RESULTS (SEER) medulloblastoma (MB) and primitive neuroectodermal tumor (PNET) outcome data. The aim of this study was to identify and optimize predictive outcome models.

Materials And Methods: Patients diagnosed from 1973 to 2009 were selected for analysis of socio-economic, staging and treatment factors available in the SEER database for MB and PNET.
