GI cancer pain is a prevalent and costly condition. Medical therapy is not always effective for managing GI cancer pain; there is a need for drug-free alternative to complement or even replace medical therapy, such as opioids. This study will evaluate a novel technology called virtual reality (VR). Users of VR wear a pair of goggles with a three-dimensional screen that creates a sensation of being transported into lifelike worlds. Evidence shows that VR can reduce pain through many different mechanisms. Research shows that VR can also help train people in new skills, such as to meditate, breathe deeply, and learn how to cope with pain.
In this study, patients with GI cancer pain will be randomized into three groups of equal size: (1) immersive skills-based VR therapy; (2) immersive distraction VR therapy; and (3) non-immersive sham VR using 2D videos displayed in a VR headset. The skills-based treatment will use virtual healing environments to teach patients about meditation, breathing exercises, and pain management. The distraction treatment will use immersive videos that are designed to take the mind off of pain. The sham VR will use VR goggles, but patients will only watch a two-dimensional video rather than a 3D, immersive experience.
Eligible patients will have GI cancer pain, meaning belly pain at least 5 points above the national average on the NIH PROMIS GI Scale as well as having a GI cancer diagnosis. . The study will exclude people who are under 18 years of age, unable to understand the consent form, expected to live less than 3 months, brain tumors not responding to treatment, or injury that makes it difficult to wear something on their face.
Randomization between groups will occur using a computer program called REDCap and will be performed after obtaining patient consent for participating in the study. The VR goggles will be shipped via FedEx to patients in all three groups, along with instructions for use. Patients will then be asked to actively use the headset for four weeks on a daily basis, following the specific instructions for their assigned intervention. In addition, patients will wear a Fitbit watch on their wrist during the study, as tolerated, to monitor step counts and sleep. Participants will fill out a set of weekly questionnaires that will be sent via email.
In order to show a difference between the active VR treatments and the sham VR control treatment, the investigator will recruit a minimum of 120 patients in each arm of the study. This calculation is sufficient to demonstrate clinically meaningful differences in the primary outcome, which is Gastrointestinal belly pain levels as measured by the NIH Patient Reported Outcome Measurement Information System, or PROMIS® questionnaire. PROMIS is a well-validated set of questionnaires that measure different aspects of quality of life; for this study the investigator will focus on PROMIS Gastrointestinal belly pain, Global physical and mental health, and Social isolation. Daily pain catastrophizing, Milligram morphine equivalent daily dose, Simulator sickness, Pain treatment satisfaction, Pain self-efficacy (PSEQ), baseline demographic information, Pain Diary, and Pain Behaviors will also be measured. The investigator will compare the number of steps taken per day and sleep levels among the three groups using statistical tests that account for potential difference among the groups. Finally, the investigator will perform statistical analyses to identify whether there are individual patient characteristics that predict response to VR therapy. The goal will be to develop a mathematical algorithm that optimized patient selection to make more precise treatment decisions with VR.
