Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Intervention: The exercise intervention will involve a minimum prescription of 150 minutes of moderate intensity aerobic- and resistance-exercise each week, with the type, intensity and duration per session individualised according to patient’s interests, fitness, presence of treatment-related side effects and co-morbidities. That is, while each woman’s exercise program will be individualised, total exercise dose prescribed per week will be at least 150 minutes of moderate-intensity exercise each week. For example, patient #1 may accumulate the required exercise dose by walking 3 days/week for 30 minutes and undertaking resistance-based exercise (using machine weights) for 30 minutes on an additional 2 days/week. Patient #2 may exercise (including walking, stationary cycling and resistance-based exercise using hand weights) twice daily for 10-15 minutes.
In line with exercise promoted within breast cancer rehabilitation models, the intervention will encourage women to exercise in both a supervised and unsupervised setting.
However, given the patient population to be studied, and that safety is a primary outcome of interest, unsupervised sessions will be introduced slowly. Participants will receive a workbook that includes information relating to the exercise program and a logbook to record details about the exercise sessions, as well as presentation of adverse events. All women will perform the supervised sessions at their homes (or another location as specified as convenient for the participant (e.g., local gymnasium) under the supervision of a trained Accredited Exercise Physiologist (AEP).
The study is a randomised wait-list study with a two-group design. The wait-list control group will be provided with a modified intervention; that is, the exercise program will be delivered with less face-to-face contact with the AEP (that is, 5 sessions instead of 20 sessions). However, the dose of exercise prescribed will be identical in both groups (150 minutes of moderate-intensity exercise/ week). Group 1 (immediate-intervention group) will attend 20 sessions with an AEP over the 12 weeks (2 sessions per week for the first 8 weeks and 1 session per week for the final 4 weeks). Group 2 (wait-list control) will attend 5 sessions with an AEP over 12 weeks (the five sessions will be scheduled taking into consideration AEP clinical judgement and participant preference). All participants will also complete unsupervised sessions throughout the 12 weeks under the guidance of the AEP.

Comparator / control treatment
There will be a wait-list control group who wait 12 weeks prior to participating in the exercise intervention. Following the assessment at 12 weeks post-baseline the wait-list control group will commence the exercise intervention. As with the immediate-intervention group they will complete 150 minutes of moderate-intensity exercise/ week; however they will only attend 5 supervised sessions with an accredited exercise physiologist (AEP). These sessions will be scheduled taking into consideration AEP clinical judgment and participant preference, with a focus on ensuring safety and feasibility of meeting the exercise goal.

Eligibility
Key inclusion criteria
Women aged 18 years or older (i.e., adults who are able to provide informed consent); reside or work in greater Brisbane (i.e., living within a 60 kilometre radius of the CBD); diagnosed with breast cancer stage II+; treated at one of the referring hospitals. The residence criterion will allow for the Accredited Exercise Physiologist (AEP) to travel to participants’ homes for intervention sessions. All participants must be undergoing or have completed treatment within the past 24 months, with the exception of hormone therapy. Additionally, women will be assessed on a range of factors to determine their disease burden; eligible participants must currently not meet national physical activity level recommendations (<150 minutes of weekly physical activity) PLUS meet one or more of the following criteria: confirmed clinical diagnosis of: (i) at least one co-morbidity or chronic disease (hypertension, hypercholesterolemia, overweight or obese [body mass index>25], classified as osteopenic or has osteoporosis, type II diabetes), or (ii) at least one chronic breast cancer treatment sequelae (lymphoedema, upper-body morbidity, neuropathy, fatigue, arthralgia). We will also accept self-report of moderate to severe in intensity treatment sequelae, even in the absence of a clinical diagnosis. This self-report criterion is necessary since treatment-sequelae are not routinely screened, detected and recorded by follow-up care (Cheville et al. 2012). Our self-report measures are ones that we have included our prospective cohort studies.

Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Strategy 1: Breast care nurses (BCNs) at one public and two private Brisbane hospitals will review medical records of women diagnosed 0-36 months prior. BCNs will hand-deliver whenever possible (during standard clinical follow-up appointments; e.g., at the standard 12-, 18- and 24-month follow-up), or send, a basic information pack about the study, requesting consent for researchers to contact them. Information on this process will be collected. BCNs will stress the targeting of the study to women potentially doing less well, i.e., even if they are not feeling well and/or have little history of exercise, that this intervention is designed specifically for them. Researchers will contact potentially eligible women, ascertain interest in participating in the study, administer eligibility screening, gain consent and commence data collection and intervention.
Strategy 2: We will also seek eligible participants via the National Breast Cancer Foundation register4, a national online database where the public can sign up to receive information about breast cancer research projects that require participants. Register4 aims to speed up the research process by bringing together researchers and willing and potentially eligible participants. At this stage, there is no fee for researchers to use Register4. It is estimated that 1400 Queensland women with breast cancer are registered with this database, all completed a characteristics survey.
Strategy 3: Media/social announcements will be placed in various locations about the aims of the trial and encouraging women to contact the study team if eligible. CIA has used this type of recruitment strategy in the past, with success. Advertisements about the study will be placed in local media as well as in breast cancer-specific newsletters (e.g., Breast Cancer Network Australia).
Recruitment brochures will be professionally designed, and developed under the guidance of CIC Young, in collaboration with women affected by breast cancer, and specifically address common concerns that may hinder women from enrolment; for example feeling too ill, too fatigued, or too much in pain to exercise, or being concerned that exercise may result in more symptoms, or being too busy to fit exercise into ones daily life. Our previous exercise trials that have required recruitment of women with specific criteria (e.g., women lymphoedema after breast cancer) have demonstrated that strategy 1, 2 and 3 contribute to 45%, 50% and 5% of the sample recruited. Due to the nature of this trial and the high level of interest and involvement of our AI clinicians, here we anticipate recruitment rates of 60%, 35% and 5% from strategies 1-3, respectively.
Following recruitment, central randomisation by computer will occur.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Stratified randomisation: Participants will be randomly assigned to either the immediate intervention or wait-list control group with a 1:1 allocation as per a computer generated randomisation schedule stratified by treatment time period (i.e., during treatment or post-treatment)

Other design features
Modified wait-list control trial: the active treatment group will receive the intervention for 12 weeks following the baseline assessment, During this period the wait-list control group will receive no intervention. At 12 weeks both groups will complete an assessment of primary and secondary outcomes. Following this the active treatment group will receive no further intervention, while the wait-list control group receive a modified intervention (i.e., the exercise volume will be identical to the original intervention; however, it will be delivered via a less supervised model of care). Both groups will complete the same assessments 12 weeks later (i.e., 24 weeks after the baseline assessment).

Summary
Brief summary
The primary purpose of this trial is to evaluate the safety and feasibility of exercise in women who are either undergoing treatment or have recently completed treatment for Stage II+ breast cancer.
Who is it for?
You may be eligible to participate in this trial if you are aged 18 or over, reside or work in greater Brisbane, and have been diagnosed with stage II+ breast cancer for which you are either still undergoing treatment, or completed treatment within the last 24 months. All participants must also report at least one cancer-related or treatment-related health condition, e.g. fatigue, obesity, high blood pressure etc.
Study details
All participants in this trial will be randomly allocated (by chance) to receive the exercise program at enrolment, or 12 weeks following enrolment. The exercise program lasts for 12 weeks and involves completing 150 minutes of moderate intensity aerobic and resistance exercise under the guidance of an accredited exercise physiologist (an allied health professional with expertise in prescribing exercise to people with chronic diseases). Supervised session (between 5 and 20 sessions) will be scheduled for a time and location that is convenient to each participant. Participants will be asked to report any side effects of the treatment and complete questionnaires and function/fitness testing to evaluate the exercise program.
It is hoped that the findings from this study will inform physicians and patients on the safety and feasibility of exercise in breast cancer patients with a high disease burden, in the hopes that it may be prescribed as a safe and effective adjuvant therapy for these patients to improve function, quality of life and survival.
