Purpose: To provide an exhaustive review of the neuropsychological examination as conducted in brain tumor clinical trials over the last 30 years and to provide objective ratings about the reliability and suitability of such tests in neurooncological research and clinical practice.
Methods: Methodologies and tools provided by the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) were exploited in order to assess the measurement properties of questionnaires and performance-based instruments used to evaluate cognitive functioning in brain tumor clinical trials from 1997 to 2017.
Results: Twenty-six brain tumor clinical trials were analyzed and an overall set of 10 neuropsychological tests was identified.
