Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The program will be delivered by trained clinicians in existing community facilities (e.g. physiotherapists or exercise physiologists close to participant home). We have deliberately chosen to position the study in a real world setting to ensure that the results will reflect what could be readily achieved in Australia and be more rapidly translated into clinical practice. Participants will be allocated to an individualised progressive preoperative exercise and education program (intervention group) or usual care alone (control group). All patients will undergo a baseline assessment prior to being randomised into either the preoperative exercise and education program (intervention) or usual care (control), and assessment week prior to surgery. The baseline and week before surgery assessments will collect subjective data with a self-reported questionnaire (measuring Duke Activity Status Index (DASI), Quality of life (SF-36v2), Physical Activity Questionnaire, Numerical Pain Rating Scale (NPRS) and Fatigue Severity Scale (FSS) and objective data with an assessment (includes a cardiorespiratory exercise test (CPET), a five times sit to stand test (5TSTS) and six minute walk test (6MWT)), for approximately one hour. Due to pandemic restrictions at the participating centres, the 5TSTS test will be performed by a trained clinician via video call in patients own home. The CPET and 6MWT assessments will be restricted and not uniformly assessed to all participants.

Individualised preoperative exercise and education program (Intervention group)
The main aim of the exercise program is to increase aerobic capacity and peripheral muscle endurance, muscle strength and respiratory muscle function and to educate participants to perform the exercise at home and about the surgical process. The individualised exercise program will follow the FITT-VP (frequency, intensity, time, type, volume and progression) principle suggested by the American College of Sports Medicine and will be delivered using three main components:

1) Supervised, individualised, progressive exercise program: The exercise program will consist of a 50-min individualised (one-to-one) training session with a physiotherapist or exercise physiologist, three times a week, for 4 to 8 weeks (range from 12 to 24 sessions). The exercise program will be tailored to each patient based on a health assessment, taking into consideration patients’ current health status, physical activity level, presence of co-morbidities and medical history. Each session will include warm-up (walking, cycling), aerobic/anaerobic exercises (cycle ergometer, treadmill, rowing machine, marching or running on the spot), resistance exercises (squat, push-up, shoulder press, hamstring curls, dumb-bell deadlift, biceps curl and overhead triceps extension), respiratory exercises (Deep breathing, relaxed breathing huff and cough (ABCT)), and cool-down activities (triceps, lower back, hip flexors, quadriceps, hamstrings, calf muscles, light jogging, walking or stretching). The aerobic exercises will be based on the individuals rated perceived exertion (modified Borg Scale) and the resistance training will be performed at an intensity of 40% to 60% of the 1-repetition maximum.

2) Home exercises (4 times/week): Home-based functional exercises will be prescribed by the treating physiotherapist or exercise physiologist to increase aerobic capacity and respiratory muscle function, including exercises with resistance provided by bodyweight, including push ups, squats, step ups. On the days participants are not attending the one-on-one training session, they will be instructed to perform the exercises for 30 minutes at home.

3) Daily physical activity advice: In addition to home exercises, participants will be encouraged to walk continuously for at least 30 minutes daily using an activity monitor. Participants will be asked to keep a daily diary of the number of steps per day and number of home exercises performed during the entire preoperative period. Step count will be extracted from the activity monitor daily by the participant, and all activity monitor data will be checked by the research team once the device has been returned. The access to this information will be limited to you and the research team. Once participation have been completed, the research team will delete all data from the activity monitor. The information stored on the activity monitor will be erased completely. No one, apart from the study investigators will have access to the data collected. No data collected from the activity monitor will be sent to any of the involved institutions. The results from the study will not be used to register the activity monitor.

The preoperative exercise program is 4-8 weeks, leading up to a week prior to the patients' surgery and includes:
- Up to 24 sessions x 50 minutes: Supervised, high-intensity training. Individualised exercise prescription, progression and follow-up with local physiotherapist or exercise physiologist either face-to-face or via tele-health.
- Up to 24 sessions x 30 minutes: Unsupervised home exercise.
- Up to 56 walking sessions x 30 minutes: Advice to walk continuously (30 minutes daily).

Treatment will be administered by local registered physiotherapists or exercise physiologists who will educate and provide high-intensity interval training, home exercises prescription and progression and physical activity advice in accordance with the study protocol. The adherence to the exercise program will be encouraged by the treating physiotherapist or exercise physiologist and by a team member that will message and/or call patients to check their compliance (i.e. log book).

Rehabilitation
Comparator / control treatment
Usual care (control) group
All participants involved in the trial will be recruited 4-8 weeks prior to surgery, will undergo a baseline assessment prior to being randomised, and an assessment week prior to surgery. Participants allocated to the control group will receive usual care consisted of nutritional counselling and advice on smoking cessation and reduction of alcohol intake, delivered by the surgeon and in preadmission clinic (CNC, dietician) as per standard preoperative care. No exercise advice will be provided and patients will be instructed to maintain their normal daily activities.

To measure their objective level of physical activity during the preoperative period, participants will be given an activity monitor in the week prior to their second assessment. Participants in the usual care (control group) will be asked to maintain their normal activities during this period. All feedback and incentivising features will be deactivated. Once the activity monitor is returned, the research team will erase the data completely from the activity monitor. The baseline and week before surgery assessments, completed by all participants, will collect subjective data with a self-reported questionnaire (measuring Duke Activity Status Index (DASI), Quality of life (SF-36v2), Physical Activity Questionnaire, Numerical Pain Rating Scale (NPRS) and Fatigue Severity Scale (FSS)) and objective data with an assessment (includes a CPET, 5TSTS and 6MWT). The 5TSTS will be performed one-on-one with physiotherapists either face-to-face at the study sites or via tele-health. Duration of the assessments is approximately one hour. Due to pandemic restrictions, CPET and 6MWT assessment are restricted and not uniformly available to all patients.

Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The randomisation sequence will be prepared a priori using a central secure randomisation service to ensure concealment of treatment allocation. Central secure randomisation service is completed by computer. A randomisation module will be created by the trial's statistican and uploaded by an independent Research Officer not involved in the trial, into the Research Electronic Data Capture (REDCap) database.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
1:1 allocation ratio in random permuted blocks of sizes 4 or 2 stratified by hospital, to ensure balance in treatment assignment within hospital

Efficacy
Statistical methods / analysis
To achieve the primary aim of the study, 172 participants will provide 90% power to detect a difference of 25% in complication rates between the intervention and control groups. This difference was considered clinically meaningful by our clinical and consumer panel. These calculations were based upon the overall complication rate being 50% in the control groups, based on our current clinical experience, allowing for up to 5% loss to follow-up and a two-side alpha of 0.05. The 5% loss to follow-up was estimated from our previous prospective clinical trials. Sample size calculations have been conducted using PASS15 software.

Summary
Brief summary
This study is investigating the effectiveness of an individualised, preoperative exercise and education program on post-operative complications in patients undergoing major abdominal cancer surgery.

Who is it for?
You may be eligible for this study if you are aged 18-80 years and are undergoing elective major surgery for advanced or recurrent gastrointestinal cancer (i.e. pelvic exenteration, cytoreductive surgery, oesophagectomy, hepatectomy, gastrectomy or pancreatectomy).

Study Details
Participants will be randomly allocated (by chance) to either:
(i) progressive preoperative exercise and education program, delivered over 4 to 8 weeks prior to surgery
(ii) usual care (nutritional counselling, advice on smoking cessation and reduction of alcohol intake)
Participants will then be followed up to 3 months post-surgery and will be asked to complete self-administered questionnaires at different time points to collect information on health complications and quality of life.

This trial seeks to determine the effectiveness and cost-effectiveness of the preoperative exercise program, on reducing postoperative complications, length of intensive care and hospital stay, and improved quality of life, which will provide policy decision-makers with evidence to support reimbursement of preoperative exercise programs.
