Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Participants will participate in an initial assessment conducted by a senior physiotherapist to determine baseline exercise tolerance and other descriptors. This includes a 6 minute walking test (6MWT) and a balance/frailty assessment called a short physical performance battery (SPPB). A quality of life survey (QLQ C30) will also be assessed at this time.

They will then participate in a 2x weekly, one hour in length duration tailored supervised exercise program. This is conducted by a senior physiotherapist and 4th year physiotherapy students from Curtin University.

Participants recruited may be currently receiving neoadjuvant chemoradiotherapy (CRT), have finished CRT on not completing CRT. The intervention is carried out despite their current CRT as to not impact on their cancer care. It has already been proven that exercise is safe at any point within the patients' treatment journey and this is why this approach was taken.

The program will consist of a walking program (determined from their 6MWT result) and resistance exercises via standard gymnasium equipment. The program is run as a group class, with a maximum of 10 participants per class.

Their program will be documented and progressed / regressed as deemed appropriate by the supervising physiotherapist. The participants will be asked to exercise at a 'moderate intensity' which is described as 'difficulty walking and talking'. The walking program is implemented on a flat walking track within the hospital, and resistance exercises are completed on standard gymnasium equipment in the Physiotherapy gym. These include, upper limb exercise with free weights, sit to stand, step ups, calf raises, body weight push up, large muscle group exercise on gym equipment (leg press, latissimus dorsi pull down, tricep push, Smith machine etc).

At the end of the 6 week program, the physiotherapist will repeat the initial assessment as a discharge assessment. As patients CRT treatment time / time to surgery differs for each surgical group - patients attend the surgical gym class for 6 weeks which is usually between 1-2 weeks pre-op. Adherence to the program is monitored via WebPAS - on online booking system used by the Physiotherapy clerks. Adherence is measured as appointments attended.

Once the patient is discharged from hospital, we will record the patients’ length of stay in ICU and in hospital and post-operative complications occurred during their inpatient stay. If required, medical records will be pulled to allow for data collection.

Efficacy
Statistical methods / analysis
A sample size calculation (G*Power) has determined that a minimum of n=38 participants has 80% power (alpha=0.05) to detect an average 25m improvement (Standard deviation (SD)=60) in the 6MWT (primary outcome measure). This sample is adequate for a repeated measures analysis over two time points in one group with 3 covariates.

Descriptive statistics of baseline demographic variables, pre and post-op measures will include means and SDs or medians and interquartile range (IQR), depending on normality, for continuous data, and frequency distributions for categorical data. Univariate differences in pre-operative pre-post measures from Phase 1 (Prehabilitation exercise program phase) will be assessed using t tests or Mann-Whitney U tests for continuous data and chi-squared tests for categorical data. Linear mixed models with random subject effects (to take into account between subject differences at baseline) will be used to examine pre-post mean changes in 6MWT and other secondary outcomes including frailty, strength and QOL outcomes. Length of stay (LOS) in ICU and hospital and days to mobilisation will be examined using Kaplan-Meier survival analysis and Cox regression models. Post-op PPC indicators in relation to fitness (6MWT improvement) will be examined using logistic regression models. All models will be adjusted for age, sex, pre-surgical chemotherapy. Data analysis will be done using Stata 16.0 (StataCorp, College Station, TX). P-values <0.05 will be considered statistically significant.

Summary
Brief summary
The purpose of this study is to determine whether a physiotherapist-led exercise prehabilitation program is effective in improving exercise tolerance, reducing hospital length of stay, and reducing post-operative complications in patients undergoing cancer surgery.

Who is it for?
You may be eligible for this study if you are aged 18 years or older, and are scheduled for complex surgery with a planned long anaesthetic time for upper gastrointestinal cancer, bowel cancer, or sarcoma. You will be included if you are receiving additional chemo radiation treatment or not.

Study details
All participants will receive a 6-week exercise program prior to surgery consisting of 2 sessions per week supervised by a physiotherapist. Sessions will be one hour in duration, and involve a walking program and resistance exercises using gymnasium equipment. The prescribed exercises will be tailored to each participant based on fitness levels assessed prior to the exercise program. Participants will complete a number of tests/questionnaires to assess exercise tolerance, frailty, strength, and quality of life before and after the 6-week exercise program, and will be monitored post-surgery until your hospital discharge date to record the length of stay in intensive care, time to mobilise out of bed, post-operative complications, and length of hospital stay.

It is hoped that this study may demonstrate that an exercise prehabilitation program is effective at improving physical fitness and post-operative outcomes in patients undergoing complex cancer surgery.
