Development and Validation of a Novel Functional Eye-Tracking Software Application for Cancer-related Cognitive Impairment (CRCI)

Study Overview
=================
Brief Summary
-----------------
This study aims to develop and validate a sensitive and non-invasive eye-tracking software application.

Detailed Description
-----------------
This study will obtain participant responses to brief cognitive tests designed to evaluate several key functions known to be affected by the Cancer-related cognitive impairment (CRCI) and non-invasive eye movement measurements in response to visually presented stimuli during specifically designed eye-tracking tests. The study data will be used to develop machine learning algorithms and validate a software application intended to track the progressive component of the Cancer-related cognitive impairment (CRCI) and associated cognitive changes.

* Device: Eye-Tracking


Participation Criteria

Eligibility Criteria
-----------------
Inclusion Criteria: For all participants: Able to provide informed consent. Visual acuity sufficient to be able to read the consent form with corrective lenses. Over 18 years of age. English- or French-speaking. For patients only: Initial diagnosis of breast cancer stage I-IIIA and scheduled chemotherapy First-time cancer diagnosis. ECOG performance < 2 Receiving curative intent chemotherapy: either Adriamycin/Cyclophosphamide for 4 cycles followed by weekly Taxol for 12 cycles or Taxotere/Cyclophosphamide for 4 cycles Exclusion Criteria: For all participants: Evidence or medical history of neurological/psychiatric issues known to affect movements and oculomotor control. Presence of comorbid neurological conditions to avoid eye movement anomaly confounds (Strabismus, cranial nerve palsy, stroke-causing hemianopsia). Diagnosis of macular edema or other pre-existing ocular conditions that would prevent participants from performing the eye movement assessments. Previous history of cancer or chemotherapy Distant metastases Recent (less than three months from enrollment) start of, change of dose, or irregular use of, new prescription drugs known to influence ocular motor visual function, such as benzodiazepines, antipsychotics and anticonvulsants. Occasional use of benzodiazepines for medical procedures is permitted, at the investigator's discretion, but should not occur within a short time period prior to or during an eye movement assessment. Diagnosis of a substance abuse disorder. Recreational drug use (e.g., alcohol, marijuana) is a potential exclusion criterion that will be determined on an individual basis as per the discretion of the research team. All recreational drug use will be documented.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change from Baseline in Symbol Digit Modalities Test (SDMT) score at Month 36 | The SDMT is used to assess divided attention, visual scanning, tracking and motor speed. Using a reference key, the examinee has 90 seconds to pair specific numbers with given geometric figures. Scoring involves summing the number of correct substitutions within the 90 second interval. | Baseline and Month 36 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change from Baseline in The Controlled Oral Word Association Test (COWAT) scores at Month 36 | The Controlled Oral Word Association Test from the Halstead-Reitan Neuropsychological Battery is a verbal fluency test in which participants are asked to say as many words as possible from a given category and in a specified timeframe (typically 60 seconds). | Baseline and Month 36 | 
| Change from Baseline in The Trail Making Test (TMT) Parts A & B scores at Month 36 | The Trail Making Test (TMT) is a neuropsychological test that provides information on visual search, scanning, speed of processing, mental flexibility and executive functions. The TMT consists of two parts. TMT-A requires an individual to draw lines sequentially connecting 25 encircled numbers distributed on a sheet of paper. Task requirements are similar for TMT-B except the person must alternate between numbers and letters (e.g., 1, A, 2, B, 3, C, etc.). The score on each part represents the amount of time required to complete the task. | Baseline and Month 36 | 
| Change from Baseline in The Hopkins Verbal Learning Test-Revised (HVLT-R) scores at Month 36 | The Hopkins Verbal Learning Test (HVLT-R) is a neuropsychological test that provides information on verbal learning and memory. The assessment consists of memorization of a list of words to test the ability to recall immediately after memorization (immediate recall) and after a 20-minute delay (delayed recall). | Baseline and Month 36 |
