Interventional
Description of intervention(s) / exposure
Phase 1 Randomised-controlled trial. Following the completion of written informed consent, participants will be stratified (by cancer type) and randomised (1:1) to one of two groups consisting of: a) the prehabilitation intervention group or b) usual care group.

The intervention will consist of a supervised exercise training session by an accredited exercise physiologist once every three days (estimated four weeks) up and until 3-5 days before surgery in a gym setting. If the scheduled date for surgery is > 4 weeks, or is delayed, participants will continue attending supervised exercise training sessions as per the protocol. Each exercise training session will commence and conclude with a 5-minute warm up and cool-down on a self-selected apparatus (treadmill; stationary bicycle; cross-trainer) and can be conducted in a group or individually. All training will be Aerobic and will be conducted predominantly on a cycle ergometer with additional aerobic exercises (e.g. treadmill, step-ups, cross-trainer) will also be used to maintain participant engagement with the program. The prescribed intensity will be set at 40-70% of HRR and/or a rating of perceived exertion of 11-16 (“fairly light” to “hard”; 6 – 20 scale). Exercise training sessions last between 45-60 minutes, which will aim to include approximately 30 minutes of dedicated aerobic training.

The Accredited Exercise Physiologist who is training the participants may make amendments to the training protocol on an individual basis. However, the exercise sessions will be delivered in a group setting based on particpants availbility. This will allow potential adjustments to the exercise type, intensity and volume during the session based on the patient’s perceived exertion. All amendments must be recorded.

Physical assessments will be performed pre-intervention, Post-exercise intervention completion (approximately 48 hrs pre-surgery), and at 30 days following surgery. Peri- and post-operative outcomes will be collected for all participants. Following the 30-day post-operative testing time-point, both groups will be invited to receive four weeks of biweekly supervised exercise training.

Missed sessions should aim to be rescheduled within the same week, if possible, while allowing at least 48 hours between exercise sessions. The total number of supervised exercise sessions should not exceed three per week. Attendance will be defined as the number of in-person exercise sessions divided by the number of planned in-person sessions. If any sessions are missed, the number and reasons should be recorded. Every attempt should be made to reschedule missed sessions.

Lifestyle
Comparator / control treatment
The usual care group will comply with normal BHS procedures. There is no current prehabilitation approach employed at Ballarat Health Services. At present, patients have an initial assessment that include outcome measures (6MWT and then depending on their current status potentially Upper Limb or Lower Limb strength tests, balance, questionnaires). Patients will then be booked in to 1-2 group sessions per week in conjunction with a HEP or just a HEP if they can’t attend supervised sessions. The primary focus is to increase cardiovascular fitness with the addition of strength based exercises to assist with improving function. This will then continue up until surgery/treatment date.

Randomisation will be completed via an online software application (Sealed Envelope Ltd. 2017. Simple randomisation service [Online] Available from: https://www.sealedenvelope.com/simple-randomiser/v1]).
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). Block randomisation in random blocks of 2, 4 or 6 will be conducted by an individual external to the investigation.

Statistical methods / analysis
Primary and secondary outcomes analysed and presented using appropriate statistical procedures will be undertaken. Data will be tested for normality (of distribution) using a Shapiro-Wilks test. Random effects mixed modelling with Bonferroni post-hoc analyses will be used to compare mean changes in outcomes between groups at each assessment period, with time (pre-treatment, post-treatment, 30-day post-operative follow-up) and group allocation (intervention or usual care) as the fixed factors. A group by time interaction term will be used to formally test for differences between groups. Data will also be scrutinised for within-group differences. Multiple regression will be employed to determine the association between the change in measured physiological and psychosocial outcomes, and operative outcomes. Data analysis will be conducted using SPSS version 24.0 and Stata/IC general purpose statistical software. Analysis of biochemical samples will employ a principle component method (Factor analysis for mixed data), and multiple linear regression will be employed to compare continuous and phenotypic characteristics in each participant group. Descriptive statistics will be presented as group mean ± standard deviation (SD), or median (interquartile range) where appropriate. An alpha of P<0.05 will be used to denote statistical significance.

Summary
Brief summary
This study aims to generate new knowledge on the feasibility and effectiveness of pre-operative exercise training (‘prehabilitation’) to induce clinically relevant improvements in physical fitness (cardiopulmonary function) in patients with prostate, colorectal or breast cancer undergoing surgery in the Grampians region of Victoria.

Who is it for?
You may be eligible to join this study if you are aged 18 years or more, are scheduled for prostate, colorectal or breast cancer surgery, and are able to partake in exercise training.

Study details
Participants in this study will be randomly allocated (by chance) into one of two groups. Participants in one group will continue to receive usual care. Participants in the other group will undertake a supervised exercise training session once every three days (estimated four weeks) up to 3-5 days before surgery. Sessions will involve aerobic training on apparatus such as treadmill, stationary bicycle and cross-trainer for 45-60 minutes.

All participants will undertake physical assessments at enrolment, post- exercise intervention completion (approximately 48 hrs pre-surgery), and at 30 days following surgery. They will also be required to complete questionnaires to measure quality of life and physical and emotional well-being.

Given that the body of physical activity research in cancer prevention, management and therapy has focused almost entirely on post-operative exercise regimens, we are hoping to address this gap in the literature in regards to pre-operative exercise and provide a pathway to fixed pre-operative exercise model for future use in the Grampians region of Victoria
