Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Participants will undergo a structured and supervised high intensity interval exercise program over three sessions per week on an individual basis for 4 weeks pre-operatively. Each participant in the treatment arm of the study will have a prescribed exercise program by a physiotherapist and will choose to do it at a hospital gym or at home with supervision via a video link with heart rate monitoring using an android tablet (supplied to the participant.
Each supervised session will comprise of at least 30 minutes of aerobic exercise in the form of a cycling program on an electromagnetically braked cycle ergometer, for patients exercising at home this will be supplied at no-cost and delivered. The cycling program will be prescribed at 60% of peak power achieved during a cardiopulmonary exercise test (CPET). Progression of the intensity and duration of the program’s aerobic components will be titrated to a dyspnoea score of 4-6 (Borg scale) or a rating of perceived exertion (RPE) of 14-16 depending on the symptom of exercise limitation.
All study participants will be asked to maintain an exercise diary for the duration of the treatment phase of the study.

Eligibility
Key inclusion criteria
Aged 18 years and over
- Written informed consent
- Operative procedure planned at least 4 weeks from randomisation date
Patient must be assessed as fit for surgery by the treating Surgeon based on past medical history and CPET testing.
- Patient must be undergoing a major upper gastrointestinal surgical procedure with neoadjuvant therapy including the following:
* Oesophagectomy
* Total/ Subtotal Gastrectomy
* Pancreaticoduodenectomy
* Major Liver Resection( >2 segments)
Minimum age
18 Years
Maximum age
No limit

Key exclusion criteria
Unresectable/ metastatic disease at any point within the study
- Progressive disease during neoadjuvant chemotherapy
- Known Class III/IV heart failure or moderate to severe pulmonary hypertension
- Poorly controlled cardiac arrhythmia/ excluded by an anaesthetist or a cardiologist
- Uncontrolled hypertension >180/100
- Angina
- Claudication
- Vascular aneurysm
- Severe COPD with FEV1<50% predicted
- For safety reasons, the study cannot enrol people who don’t speak basic English as in a maximal intensity exercise program we cannot provide a safe environment without a trained, NSW Health registered translator for every exercise session.
- Clinical decision by treating Surgeon that operative procedure will be scheduled less than 4 weeks

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Central randomisation computer.
Treating surgeons and outcome assessor blinded to treatment allocation
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation using a randomisation table created by computer software (i.e. computerised sequence generation)
Simple stratification according to procedure type has already been performed (I.e. oesophagectomy vs other Upper GI/ HPB resections)
