ImpRoving hEalth behaviourS for LIfe After ENdometrial CancEr Trial

Study Overview
=================
Brief Summary
-----------------
RESILIENCE is 24-week randomized controlled trial that assesses the efficacy of a web-based health platform, combined with online support from healthcare professionals, to enhance waist circumference and other vital health outcomes in endometrial cancer survivors.

Detailed Description
-----------------
Background: Individuals diagnosed with endometrial cancer are at an increased risk of cardiac complications post-treatment, particularly if having overweight or a pronounced waist size. Adopting healthy habits-like nutritious eating, regular physical activity, and effective stress management-can mitigate these risks and bolster overall health. However, many cancer survivors find it challenging to consistently adhere to these health and wellness recommendations. Objective: This study aims to determine the efficacy of a web-based health platform, enriched with professional guidance, in facilitating healthier lifestyles for endometrial cancer survivors. This would encompass enhancements in nutrition, physical activity levels, and mindfulness practices. Study Design: Group 1 (Intervention Group): Participants will engage with the web-based health platform daily for the initial 16 weeks with expert guidance. Subsequently, participants will navigate the platform independently for the next 8 weeks. Group 2 (Control Group): Participants will initially be provided with standard publicly accessible health information. After the primary 24-week period, participants will gain access to the web-based wellness platform. Common Elements: Both groups will have access to general health information and will benefit from supportive calls. To monitor their physical activity, all participants will be equipped with an activity tracker.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Intervention group<br>Participants will receive the intervention for 24 weeks. The first 16 weeks will involve an intensive behavioral program (web-based health platform plus online healthcare professional support), followed by an 8-week maintenance period (web-based platform alone). At baseline, participants will receive handouts with publicly available health information; they will also wear an activity monitor and receive support telephone calls for the 24 weeks. | Behavioral: My Viva Plan (www.myvivaplan.com)<br>* A web-based platform based on preventive self-care that contains tools to monitor nutrition, physical activity, and mental wellbeing will be accessed daily for 24 weeks.<br>Behavioral: Online healthcare professional support<br>* Individual and group sessions with a Registered Dietitian, Qualified Exercise professional, and Mental Health Professional for 16 weeks.<br>|
| No Intervention: Control group<br>At baseline, participants will receive handouts with publicly available health information; they will also wear an activity monitor and receive support telephone calls for the 24 weeks. | |

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change from baseline in waist circumference at week 16. | Waist circumference will be measured in centimeters (cm) using an inelastic tape at the level of the iliac crest at the end of normal expiration. | Baseline to week 16 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change from baseline in waist circumference at week 24. | Waist circumference will be measured in centimeters (cm) using an inelastic tape at the level of the iliac crest at the end of normal expiration. | Baseline and week 24 | 
| Change from baseline in body weight (in kg) at weeks 16 and 24. | Weight will be measured in kilograms (kg) in triplicate following standardized procedures; average values will be used for analysis. | Baseline, week 16, and week 24 | 
| Change from baseline in fat mass by DXA at weeks 16 and 24. | Percentage fat mass will be measured using dual-energy x-ray absorptiometry (DXA), which is a precise and reliable technique. | Baseline, week 16, and week 24 | 
| Change from baseline in appendicular lean soft tissue by DXA at weeks 16 and 24. | Appendicular lean soft tissue will be measured using dual-energy x-ray absorptiometry (DXA), which is a precise and reliable technique. Appendicular lean soft tissue will be adjusted for body weight. | Baseline, week 16, and week 24 | 
| Change from baseline in metabolic syndrome by Z score calculation at weeks 16 and 24. | Metabolic syndrome severity Z score will be calculated using waist circumference, blood pressure, high-density lipoprotein cholesterol, triglycerides, and fasting glucose data in sex- and ethnicity-specific equations. | Baseline, week 16, and week 24 | 
| Change from baseline in cardiovascular risk based on the Framingham risk score at weeks 16 and 24. | 10-year cardiovascular risk will be estimated using sex-specific Framingham risk score based on traditional risk factors. Risk is low if the score is less than 10% and high if it is 20% or higher. | Baseline, week 16, and week 24 | 
| Change from baseline in handgrip muscle strength at weeks 16 and 24. | Handgrip strength will be evaluated using a hydraulic handgrip dynamometer. | Baseline, week 16, and week 24 | 
| Change from baseline in cardiorespiratory fitness by a cardiopulmonary exercise testing (CPET) at weeks 16 and 24. | Peak oxygen uptake will be measured by gold standard cardiopulmonary exercise testing. | Baseline, week 16, and week 24 | 
| Change from baseline in health-related life improvement by the QLQ-C30 at weeks 16 and 24. | Participants will complete the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire Core-30 (QLQ-C30). Score ranges from 0 to 100. Higher scores on symptoms and single-items indicate a higher level of symptoms. | Baseline, week 16, and week 24 | 
| Change from baseline in health-related life improvement by the QLQ-EN24 at weeks 16 and 24. | Participants will complete the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire -Endometrial Cancer Module (EORTC QLQ-EN24). Score ranges from 0 to 100. Higher scores on symptoms and single-items indicate a higher level of symptoms. | Baseline, week 16, and week 24 |
