Preliminary exploration of a computerized cognitive battery and comparison with traditional testing in patients with high-grade glioma.

Background: Cognitive function is an important outcome measure in many brain tumor clinical trials, and investigators are interested in employing the most efficient methods of cognitive assessment for this purpose. Computerized testing can be appealing because of the perceived ease of use and electronic data generated. Traditional tests may have the advantage of accumulated validity evidence and comparability across historic trials.

CogState computerized memory tests in patients with brain metastases: secondary endpoint results of NRG Oncology RTOG 0933.

Whole brain radiotherapy (WBRT) is associated with memory dysfunction. As part of NRG Oncology RTOG 0933, a phase II study of WBRT for brain metastases that conformally avoided the hippocampal stem cell compartment (HA-WBRT), memory was assessed pre- and post-HA-WBRT using both traditional and computerized memory tests. We examined whether the computerized tests yielded similar findings and might serve as possible alternatives for assessment of memory in multi-institution clinical trials.

Preservation of memory with conformal avoidance of the hippocampal neural stem-cell compartment during whole-brain radiotherapy for brain metastases (RTOG 0933): a phase II multi-institutional trial.

Purpose: Hippocampal neural stem-cell injury during whole-brain radiotherapy (WBRT) may play a role in memory decline. Intensity-modulated radiotherapy can be used to avoid conformally the hippocampal neural stem-cell compartment during WBRT (HA-WBRT). RTOG 0933 was a single-arm phase II study of HA-WBRT for brain metastases with prespecified comparison with a historical control of patients treated with WBRT without hippocampal avoidance.

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

Neurocognitive function (NCF) impairment is an important component of primary and metastatic brain tumors and their therapeutic interventions. As a result, modern clinical trials of cranial irradiation for adult cancer patients have incorporated NCF testing as a primary or secondary end point. In doing so, these clinical trials have provided a novel insight into our understanding of the NCF effects of cranial irradiation and brain tumor progression.
