September 27, 2023 updated by: University of Nebraska
This study is being done to see the changes in structural and functional connectivity that happen in the brain of patients undergoing brain tumor surgery.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The purpose of this study is to visualize and quantify changes in the brain of patients undergoing brain tumor surgery through high-quality, high-resolution structural and functional brain imaging and brain connectivity measures. To understand the effects of the primary treatment for brain tumors, the investigators will determine changes in brain connectivity after surgery and correlate this with neurologic status. The investigators will prospectively collect brain imaging (MRI) and clinical data in brain tumor patients before and after removal of their tumor. Any adult patient with a brain tumor (primary or metastatic) for whom surgery to remove the tumor is planned is eligible. The investigators plan for recruitment of 30 subjects. This will include 27 subjects with brain tumors and 3 healthy controls. Both clinical and imaging data will be collected for tumor and healthy subjects. A two-part research scan (diffusion MRI and resting state functional MRI) will be performed within 1 week prior to surgery and again 2 weeks after surgery. The healthy controls will obtain identical research scans with the second session two weeks following the first session. Subjects will be also administered Neurocognitive and Qualitative Assessments at two time intervals, pre- and post-surgery (2 weeks).

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

19 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

Yes

Sampling Method

Non-Probability Sample

Study Population

Oncologists and neurosurgeons may identify their patients for potential inclusion as brain tumor subjects. The "word-of-mouth" approach will be used to identify potential healthy subjects for this study.

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Healthy subjects
Diagnostic test: MRI
A research MRI scan will be performed within 1 week prior to surgery and again 2 weeks after surgery. The surgical removal of the brain tumor(s) is not a component of this research. The MRI scan will perform both programs (diffusion MRI, resting state MRI) during the same single session. The healthy controls will obtain identical research scans with the second session between two and three weeks following the first session, since they will not undergo a surgery.
Diagnostic test: neuropsychological tests and qualitative assessment

Neuropsych Tests: COWA, Trails, RCFT, RAVLT, WMS-III subtests, NAB Digits, Grooved Pegboard, Stroop Color Word Test, verbal and spatial working memory, WRAT-IV, Word Reading subtest.

Standardized quality of life measures: MDASI-BT, FACT-Br, FrSBe
Brain tumors
Subjects with operable supratentorial brain tumors
Diagnostic test: MRI
A research MRI scan will be performed within 1 week prior to surgery and again 2 weeks after surgery. The surgical removal of the brain tumor(s) is not a component of this research. The MRI scan will perform both programs (diffusion MRI, resting state MRI) during the same single session. The healthy controls will obtain identical research scans with the second session between two and three weeks following the first session, since they will not undergo a surgery.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Brain connectivity changes
Time Frame: MRI scan will be performed within 1 week prior to surgery and again 2 weeks after surgery.
With both the functional and structural connectomes created, the investigators will compute graph network measures before and after surgical resection and assess both nodal and global network measures.
MRI scan will be performed within 1 week prior to surgery and again 2 weeks after surgery.
Neurocognitive changes
Time Frame: Cognitive tests will be performed within 1 week prior to surgery and again 2 weeks after surgery.

Meyers Neuropsychological Battery: Published reliable change indices (RCI) will be used to control for practice effects between the assessment points for all Meyers Neuropsychological Battery (MNB) subtests.

QOL inventories: Differences in scores at baseline, relative to treatment phase, will be calculated.
Cognitive tests will be performed within 1 week prior to surgery and again 2 weeks after surgery.
