Clinical Trial Summary
Recent research indicates that variability in cognitive function for brain tumor survivors
may be explained by differences in cognitive reserve (CR) and use of compensatory
strategies.However, it is unknown when cognitive function declines or survivors tap into
compensation. This longitudinal mixed methods study proposes to explore differences in
cognitive function and change over time in newly diagnosed adults with brain cancer prior to,
immediately after (within 2 weeks), and 2-3 months after radiation therapy treatment has been
completed.
Specific aims are to:
Aim1: Examine the relationship between objective and subjective cognitive function in
subjects newly diagnosed with brain cancer prior to and after XRT.
Aim 2: Explore the interrelationship between cognitive function and compensation (neural and
behavioral) by high/low CR prior to and after XRT.
Aim 3: Describe the trajectory of objective and subjective cognitive function over time by
CR, cancer type, and associated treatment-related factors.
Description:
Cognitive impairments experienced by cancer survivors, from time of diagnosis through the
health trajectory, are distressing, persistent, and negatively impact everyday function and
quality of life. While reports of cancer- and treatment-related cognitive concerns vary
substantially and may be underestimated in some diagnoses, the estimated incidence ranges
from 30% in breast cancer up to 90% in brain cancers. Those with brain cancers, including
both primary brain tumors and secondary brain metastases, often receive news of their
diagnosis during prime productive years of their lives. Due to the cognitive effects from
cancer or its treatment, most brain cancer survivors report difficulties returning to work or
maintain family demands. Survivors often report co-occurring symptoms or a symptom cluster
that include fatigue, sleep and mood disturbances, adding to multimorbidity conditions from
the psychoneuroimmunologic effects of cancer. As medical advances have fostered significant
gains in cancer survivorship and cancer is now recognized as a chronic illness, there is an
urgency to address commonly faced symptoms and chronic conditions throughout the cancer
trajectory beginning at time of diagnosis.
Cancer treatment is designed to induce cell death but when treating brain cancers, treatment
may negatively impact neurogenesis and neural repair. Previous study indicates that some
survivors of brain tumors use behavioral compensation, the investigators aim to understand
how neural compensation may be impacted. Cognitive functions associated with biomarkers
(NComp) are brain-derived neurotrophic factor (BDNF), catechol-O-methyl transferase (COMT).
As survival rises, the investigators need to identify factors that moderate cognitive
function in order to develop interventions aimed at minimizing functional decline.
This study is significant as it: 1) describes cognitive variability decline over time, and
use of N/BComp; 2) uniquely explores cognition and N/BComp over time; 3) explores moderators
of cognitive function across brain cancer survivors, 4) may lead to developing targeted
cognitive interventions.
Cognitive function impacts everyday functional abilities and quality of life, however, change
in cognition can elude detection. Discrepancies observed between subjective and objective
cognitive, co-occurring symptoms, and its relationship with cognitive reserve are new
research areas of interest in oncology. Exploring neural or behavioral compensation within
the context of cognitive reserve is novel. No known oncology studies have reported the
relationship of neural and behavioral compensation with change in cognitive function over
time. Examining the trajectory of these variables can aid in identifying potential cognitive
interventions for targeted use to prevent decline or maintain function over time.
This study is innovative because it is the first to explore the interface of
neural/behavioral compensation and the cognitive trajectory, within a framework of cognitive
reserve, in adults newly diagnosed with brain cancers.
