Cognitive function testing in adult brain tumor trials: lessons from a comprehensive review

Area of Science:

• Neuro-oncology
• Clinical Trials
• Cognitive Neuroscience

Background:

• Neurocognitive function (NCF) impairment is a significant issue in brain tumor patients.
• Therapeutic interventions for brain tumors can also impact NCF.
• Assessing NCF is vital for understanding treatment side effects and disease progression.

Purpose of the Study:

• To review clinical trials incorporating NCF testing for adult cancer patients with brain tumors.
• To analyze trial findings regarding the effects of cranial irradiation and tumor progression on NCF.
• To evaluate the types of NCF tests used, their strengths, and limitations.

Main Methods:

• Systematic review of modern clinical trials involving NCF testing in brain tumor patients.
• Analysis of NCF data from trials where it was a primary or secondary endpoint.
• Evaluation of methodologies and psychometric properties of NCF tests employed.

Main Results:

• Clinical trials provide novel insights into NCF changes due to cranial irradiation and brain tumor progression.
• Specific NCF tests have been utilized to measure these effects.
• Understanding the impact of treatments on cognitive function is improving.

Conclusions:

• NCF testing is an integral part of contemporary brain tumor clinical trials.
• Continued research and refinement of NCF assessment are necessary.
• Future directions involve optimizing NCF testing for better patient outcomes and treatment strategies.
