From data collection to clinical trials: Establishing evidences of brain tumors

Abstract

We conducted the survey of brain tumor registry of Japan(BTRJ), which has started in 1973, and performed analyses of the incidence, therapeutic methods, and treatment outcomes of primary and metastatic brain tumors based on WHO 2007 classification with the cooperation of the Japan Neurosurgical Society members. These data reveal the diagnostic and therapeutic problems associated with each type of brain tumor and will lead to clinical trials and prospective surveys to establish evidence of brain tumors as go forward.
