A Tailored Exercise Oncology Program for Neuro-Oncology Patients

BACKGROUND \& RATIONALE

Exercise, or physical activity, is beneficial for all cancer survivors. Despite this knowledge, there is generally a gap between the evidence and practice. And this gap is widened with (a) underserved tumour groups in exercise oncology, such as neuro-oncology patients, or (b) underutilized timelines across the cancer treatment phases to deliver exercise oncology education or programming.

Within Alberta (AB), the investigators have been able to very successfully implement the Alberta Cancer Exercise (ACE) program to start to address the gap between research and practice. As a hybrid implementation effectiveness study, ACE is building a model for exercise oncology delivery within standard cancer care. With over 2500 participants across AB, the investigators have substantial evidence supporting the feasibility of ACE, as well as the potential benefits. Despite these successes, ACE remains primarily represented by participants from breast, prostate, and colorectal tumour groups. This represents a lack of connection between smaller and more high risk tumour groups within referral pathways for the ACE program, both at TBCC and CCI, but also within the regional community cancer clinics (Grande Prairie, Red Deer, Medicine Hat, Lethbridge).

RESEARCH QUESTION \& OBJECTIVES

The purpose of this feasibility-implementation study is to build exercise into the clinical care pathway in neuro-oncology clinics at the two major cancer centres in AB, where all neuro-oncology patients provincially are treated (Tom Baker Cancer Centre, TBCC; and the Cross Cancer Institute, CCI). Specifically, the objectives of the proposed work are: (1) to tailor the ACE exercise program for all neuro- oncology patients, to ACE-Neuro; this includes considering additional tailoring to address needs earlier in the care pathway, from diagnosis through treatment (i.e., prehabilitation phases) and into longer term survivorship (wellness cancer survivorship care plans), (2) to provide models of delivery of exercise oncology programs to enhance access (i.e., remote delivery, home support, individual vs group), and (3) to build this systematically within the neuro-oncology clinics at the TBCC and CCI, to ensure that all patients diagnosed with brain tumours can access wellness during their cancer care journey. The investigators hypothesize that there will be improvements in patients' physical and psychosocial well-being (individual level outcomes), as well as a more integrated workflow in the clinical cancer care setting that includes exercise as part of standard clinical practice (systems level outcome). Specifically, the primary outcome of this study is to determine the feasibility of recruitment, referral, triage, adherence, and adverse events. The secondary outcome is to examine the preliminary effectiveness of the neuro-oncology exercise program on patient-reported outcomes and physical function.

METHODS

Using the successful implementation model developed in ACE, the proposed work will build a neuro-oncology cohort within a mixed methods study design. There will be multiple phases to the implementation of ACE-Neuro, including:

1. Building awareness within the clinical teams, identifying site champions, and providing educational and referral resources specific to neuro-oncology and exercise;
2. Working with neuro-oncology patients and families to develop the unique aspects of exercise programming (from "move more" programs to "exercise") to address identified needs. This co-creation process will also include the cancer physiatry team (Dr. George Francis, Dr. Lauren Capozzi) and the clinical neuro-oncology teams (Dr. Gloria Roldan Urgoiti at TBCC and Dr. Jay Easaw at CCI) to address medical clinical needs that can be addressed within the ACE-Neuro program, and clinical workflow logistics with physiatry and physiotherapy to address specific treatment-related side effects (such as limb weakness, balance, or cognitive function);
3. implementation of the ACE-Neuro tailored program, including referral, screening, assessments, intervention delivery, and follow-ups. Details of the ACE-Neuro procedures are detailed below.

REFERRAL AND RECRUITMENT

Because the main outcome of this study is feasibility, and the ultimate goal is to build ACE-Neuro into standard neuro-oncology care, no a priori sample size has been calculated. Based on current clinical numbers, and previous work done with neuro-oncology patients at CCI, the investigators anticipate approximately 25-30 eligible patients per year, per site. Our aim is to referral of all eligible neuro-oncology patients from TBCC. For recruitment, patients can:

1. self-refer (i.e. patient contacts the study team from a poster or brochure received in clinic, through word of mouth); OR study team can refer:
2. clinical team sends referral to rehab oncology via Putting Patients First Questionnaire (via ARIA).

The clinical team, based on their judgment, may not refer patients they deem to be ineligible. This may include for the following reasons:

1. Patient is not interested when exercise idea is brought up.
2. Health care provider deems patient clinically ineligible, due to disease progression, end-of-life care, or other health factor
3. Patient does not speak English
4. Other

As a feasibility study, reasons for non-referral will be tracked, with no identifying patient information, across the recruitment period. After consenting to the study, all patients will undergo a two-part screening procedure prior to beginning the exercise program:

1. Patients will complete health and medical history screening using the Health History Questionnaire, Identifying Information Questionnaire, and the Physical Activity Readiness Questionnaire; PAR-Q.
2. Patients will attend a Neuro Oncology Rehabilitation Triage Clinic, led by a Resident Physician (Dr. Lauren Capozzi; supervised by Dr. George Francis) and the ACE-Neuro Study Coordinator (Julia Daun). During this 30-minute appointment, patients will complete the Short Physical Performance Battery screening test6, and a full neurological exam, including Karnofsky performance and Eastern Cooperative Oncology Group (ECOG) scores. This appointment will assess the patients' readiness for participating in ACE-Neuro.

As part of this study, the investigators will be tracking the referral pathway, and which method of referral is most feasible as part of standard clinical workflow.

ASSESSMENTS

1. Patient-Reported Outcomes (PROs) - will include symptom burden (Edmonton Symptom Assessment Scale-Revised; ESAS-r), PA levels (Godin Leisure Time Exercise Questionnaire-Modified; GLTEQ), quality of life (Functional Assessment of Cancer Therapy-Brain; FACT-Br), cognitive function (Functional Assessment of Cancer Therapy-Cognitive Scale; FACT-Cog), and fatigue (Functional Assessment of Chronic Illness Therapy-Fatigue; FACIT-F).
2. Functional Fitness Assessments - will follow the set protocols within ACE (HREBA-CC-16- 0905_MOD12), and are designed to be able to be completed in-person or via remote delivery (online assessment). All fitness assessments will be completed by a Clinical Exercise Physiologist and will include the assessment of lower body strength and endurance (30-second sit-to-stand), static balance (single leg stance), flexibility (sit-and-reach and active shoulder flexion), and cardiorespiratory fitness (2-minute step test or 6MWT).
3. Objective Physical Activity - will be measured via the use of a wrist-worn activity tracker (WAT; i.e., Garmin vivosmart® 4). Garmin wearable PA trackers are widely used across health research, and will be provided to all participants to objectively track PA habits throughout the intervention.
4. Qualitative Interviews and Photo Elicitation: Qualitative data will be gathered across the co-creation process via interviews and photo elicitation, to inform the feasibility of ACE-Neuro, as well as to assess outcomes associated with participation in the ACE-Neuro program (benefits, barriers, satisfaction, impact on well-being). Qualitative data will be stored on a secure server.

HEALTH COACHING

In addition to exercise delivery and assessments, all participants will have the choice to participate in evidence-based health coaching calls, provided by a trained Health Coach. Health coaching is an evidence-based tool that supports positive health behaviour change across cancer populations. Health coaching calls will take place weekly for 15-30 minutes following an individualized exercise training session, and include topics surrounding goal setting, social support, stress management, maintaining motivation, and overcoming barriers. Health coaching calls will be delivered remotely (e.g., via end-to-end encrypted Zoom or phone call) at the participants' preferred date and time.

TIMELINE

The described exercise program and data collection of PROs and functional fitness assessments are in addition to standard practices. The timeline for these assessments include: baseline (at recruitment into ACE-Neuro), 12-weeks (post-intervention), 6-months, and 12-months.

ANALYSIS Quantitative analysis will include descriptive statistics (means, medians, standard deviations), and change scores to measure changes in outcomes over time. Qualitative data will be analyzed by verbatim transcription (in NVivo), using an interpretive description methodology. Both quantitative and qualitative data will be analyzed to provide a deeper understanding of the feasibility and impact of ACE-Neuro.

RELEVANCE By working directly with patients, healthcare providers, and community partners, this implementation project will develop a framework that streamlines patient triage, and provides a tailored online exercise program for neuro-oncology patients, thereby advancing exercise oncology research and clinical practice.
