The Impact of Physical Exercise on Sleep in Colorectal Cancer Patients During Prehabilitation Period

Not Applicable

• Conditions: Colo-rectal Cancer; Surgery
• Interventions: Behavioral: Prehabilitation program

• Registration Number: NCT04270500
• Lead Sponsor: Montreal General Hospital

Brief Summary

Main objective: To evaluate the bidirectional relationships between physical exercise and sleep parameters, as a part of multimodal prehabilitation intervention, on pre- and postoperative outcomes in surgical patients with colorectal cancer, in an RCT.

Secondary objective: to determine whether the levels of anxiety and depression affect these relationships.

Objectives are based on the overarching hypothesis that is sleep and physical activity influence each other through complex, reciprocal interactions including multiple physiological and psychological pathways. To achieve this, providing a multimodal prehabilitation, specifically physical exercise, involved in mental and physical health through different mechanisms, i.e., improving physical functioning and fitness, reducing side effects of cancer treatments, preventing bone loss and weight gain, improving the quality of life and sleep, decreasing symptoms of fatigue and depression.

The present is a pilot study aiming to evaluate the bidirectional relationships between sleep and physical exercise, and the preliminary outcome has important implications for informing both clinical and public health practice.

Research question: Does a multimodal intervention including physical exercise improve sleep quality and duration compared to standard of care, during the perioperative period? Conversely, does a better sleep quality and duration increases the level of physical exercise during the perioperative period? How the level of anxiety and depression will affect these relationships? If the Prehabilitation program specifically physical exercise will positively affect sleep quality and duration after surgery, in the way to be a protective factor of sleep to not be reduced by up to 55% compared to those receiving standard of care?

Detailed Description

Participants will be referred by colorectal surgery of the MUHC-Montreal General Hospital; 100 participants will be studied. Inclusion: adult patients aged 18 years and older, of either sex undergoing colorectal cancer surgery. All adult persons scheduled for resection of malignant colorectal lesions will be included. Exclusion criteria: a compromised health status (American Society of Anesthesiologists \[ASA\] class 4-5) or comorbid medical conditions interfering with the ability to perform an exercise. Patients are unable to understand the information given, insufficient understanding of English or French language to provide informed consent or who are considered unable to perform study-specific procedures. Patients that diagnosis of a sleep disorder other than insomnia (e.g., sleep-disordered breathing) or received psychotherapy specifically for insomnia, as well as a night-shift worker in the past 3 months or the next 18 months will be excluded.

Study Design: Randomized controlled trial of two parallel arms: prehabilitation program and standard of care (SOC). Informed consent forms will be signed and dated before the conduct of any study-specific procedures. After baseline assessment, participants will be random, by a computer program, allocated to either an intervention or a control group. Duration and follow-up. The intervention will last for 4 weeks pre- and 8 weeks post-surgery, for a total of 12 weeks. Site visits will occur weekly before surgery and every 4 weeks after surgery. In that period, weekly phone calls will reinforce compliance and provide tips to help patients adhere to the treatment protocol. A dedicated and specially trained research team lead by a physician, a kinesiologist, a nutritionist and a psychologist will perform the measurements and collect the demographic and surgical details of all the patients, recording daily detailed information of clinical outcomes up to 8 weeks after surgery.

Interventions: Common to both groups: as part of the enhanced recovery after surgery (ERAS) protocol as the standard of care in our institution. All participants will wear an actigraphy to objectively assess their daily physical activity and their sleep behavior. The following outcomes will be assessed for all participants, at the baseline and will be repeated after 4 weeks, before and after the surgery: sleep behaviors included sleep quality and duration, assessed subjectively and objectively. Self-reported and objective outcome measurements will be assessed from all participants such as the 6-minute walk distance (6MWD), daily activity counts, exercise tolerance (CPET) and handgrip strength, Insomnia Severity Index (ISI), Chronotype, health-related quality of life assessed by using the Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36) and the Hospital Anxiety and Depression Scale (HADS) used to assess emotional distress.

Arm && Interventions

Group	Intervention	Description
Prehabilitation program	Prehabilitation program	The preoperative period (prehabilitation) represents a more appropriate time than the postoperative period to implement an intervention. Prehabilitation is a process of enhancing an individual's functional capacity before the scheduled surgery, aimed at improving the patient's tolerance to upcoming physiologic stress, by three principal elements: exercise training, nutritional intervention, and psychological support.

Primary Outcome Measures

Name	Time	Method
Sleep quality by an Actigraphy: "change" is being assessed	4 weeks before surgery and 4 weeks after the surgery	Sleep quality will be objectively measured using the Actiwatch-2. The Actiwatch-2 (Philips, Respironics) is a small, waterproof, non-intrusive actigraphy device that is worn on the wrist of the non-dominant hand. By calculating orientation and movement, actigraphy records sleep-wake activity and provide an objective measure of sleep quality.
Pittsburgh Sleep Quality Index (PSQI): "change" is being assessed	At the baseline, it will be repeated the week of the surgery and at 4 and 8 weeks after the surgery.	This questionnaire was developed to assess the global subjective sleep disturbances of the previous month. The PSQI is a 19-item self-report measure of broad sleep disturbances over the past month and yields 7 component scores (subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbances, and daytime dysfunction), which are added to create a total score. Each score ranging from 0 to 3 and a total score range of 0-21, a score of 0 indicated no sleep problems and 3 indicated serious sleep problems.

Secondary Outcome Measures

Name	Time	Method
Daily activity counts measured by an Actigraphy: "change" is being assessed	4 weeks before surgery and 4 weeks after the surgery	The Actiwatch-2 (Philips, Respironics) provide an objective measure of the daily activity counts.
Functional capacity using the six-minute walk test (6MWT): "change" is being assessed	At the baseline, it will be repeated the week of the surgery and at 4 and 8 weeks after the surgery.	The 6MWT evaluates the ability to maintain a moderate level of physical activity reflecting the activities of daily living. Norms available: The six-minute walk distance in healthy adults has been reported to range from 400m to 700m. A lower score (reflecting less distance covered in 6 minutes) indicates worse function.
Community Health Activities Model Program for Seniors (CHAMPS) questionnaire: "change" is being assessed	At the baseline, it will be repeated the week of the surgery and at 4 and 8 weeks after the surgery.	The CHAMPS is a self-reported measure of physical activity, comprising 41 activities evaluated according to the total number of hours done during an average week. The CHAMPS has been validated as a measure of increasing levels of physical activity in older adults.; 1 METs), low-light (ie, \> 1 and ≤2 METs; eg, playing cards), high-light (ie, \>2 and \<3 METs; eg, light walking), moderate-to-vigorous physical activity (MVPA, ≥3 METs), and "total activity" (≥2 METs)
Hospital Anxiety and Depression Scale (HADS): "change" is being assessed	At the baseline, it will be repeated the week of the surgery and at 4 and 8 weeks after the surgery.	The HADS contains seven items, each scored from 0 to 3 points for anxiety and depression. It provides summary measures on a scale of 0-21, with scores exceeding 8 suggesting the presence of a mood disorder.
