Brief summary
This project aims to determine whether a comprehensive cardiac rehabilitation program including supervised exercise training is able to prevent cardiotoxicity during treatment with anthracyclines and / or anti-HER-2 antibodies in women with breast cancer. Participants will be randomly allocated to cardiac rehabilitation (intervention group) or conventional management with physical exercise recommendation (control group).
Detailed description
Cardiovascular toxicity caused by chemotherapy is the leading cause of death in patients who survive cancer. Physical exercise during chemotherapy has shown to improve quality of life and decrease the risk of death. The objective of this project is to determine whether an intervention through a comprehensive cardiac rehabilitation program including supervised physical exercise is able to prevent anthracyclines and / or anti-HER-2 antibodies-induced cardiotoxicity in women with breast cancer. For this purpose, the investigators intend to conduct a randomized controlled study including female patients managed under the same cardiotoxicity prevention protocol (clinical, laboratory and echocardiographic follow-up assessment). Patients will be randomized to a non-pharmacological intervention (participation in a multidisciplinary cardiac rehabilitation program with supervised exercise training) or control (conventional management and physical activity recommendation)\*. The investigators hypothesize that a cardiac rehabilitation program may limit chemotherapy-induced cardiotoxicity in women with breast cancer, improve cardiac remodeling assessed by echocardiography and enhance their global cardiovascular risk profile to a greater extent, compared to control group. \* OF NOTE: Due to the COVID-19 pandemics, several modifications to the original protocol were introduced for safety reasons or motivated by the health situation, namely: 1. Intervention: Change from centre-based to telematic supervised exercise training sessions provided within the cardiac rehabilitation program (intervention group) 2. Secondary outcome 4: Change in functional capacity assessed by conventional ergometry or cardiopulmonary exercise test OR the 6-minute walking test (metabolic equivalents: METs or peak oxygen consumption: VO2) 3. Recruiting centres: One centre (Hospital Universitari Vall d'Hebron) withdrew from the study due to the impossibility of assuming its execution.

|---|---|---|
| Change in left ventricular systolic function quantified by left ventricular ejection fraction and global longitudinal strain by transthoracic echocardiography | Baseline to every 3 months through study completion, at the end of the study at an average of 18 months, and every year after study completion up to a maximum of 5 years | Fall of 10 absolute percentage points of left ventricular ejection fraction with final value below 53% or global longitudinal strain fall \>15% with respect to baseline |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change in anthropometric parameters: body mass index (BMI) in kg/m^2 | Baseline and at the end of the study at an average of 18 months | Weight and height will be combined to report BMI in kg/m\^2 |
| Change in the score for anxiety assessed by the Zigmond and Snaith questionnaire to rate depression and anxiety | Baseline and at study completion, plus at the end of training (at an average of 12 to 15 months) in the intervention group | Score achieved in the anxiety subscale of the Zigmond and Snaith test for anxiety or depression, a self-applied questionnaire. Anxiety scale includes 7 items each, scored on Likert scale from 0 to 3. Global score ranges from 0 to 21, with higher scores representing greater anxiety. The authors suggest that scores higher than eleven would indicate case and more than eight would be considered probable case (Zigmond and Snaith, 1983). |
| Change in physical activity (minutes of dedicated physical activity) | Baseline and at study completion at an average of 18 months | Minutes of In- and out-of-hospital dedicated physical activity |
| Change in physical activity assessed by the score in the Godin Leisure Test Exercise Questionnaire (GLTEQ) | Baseline and at study completion at an average of 18 months | Score achieved in the Godin Leisure Test Exercise Questionnaire (GLTEQ) for quantification of physical activity. Activities are classified into three subgroups: strenuous, moderate, and light. The scores corresponding to the energy expenditure (metabolic equivalent (MET)) are obtained by multiplying activities performed for more than 15 min in a week with their coefficients. The numbers represent the MET intensity values (strenuous/ exhausting exercises: 9 METs, moderate exercises: 5 METs, and light exercises: 3 METs).The increasing scores are associated with the increasing number of exercise behaviors, providing references about the contribution of physical activity to health: the activity score of 24 units and more as active (substantial benefits); the activity score of 14-23 units as moderately active (some benefits); and the activity score of 13 units and less as inactive (less substantial or low benefits). |
| Change in lymphedema assessed by perimeter of the upper limb by cirtometry (cm), stage and grade | Baseline after surgery and 2-4 weeks after the end of chemotherapy (at an average of 12 to 15 months) | Perimeter of the upper limb by cirtometry (cm), stage and grade as defined by the Spanish Society of Rehabilitation and Physical Medicine |
| Change in health-related quality of life assessed by the Functional Assessment of Cancer Therapy - Breast plus Arm Morbidity (FACT-B+4) questionnaire | Baseline and at the end of the study at an average of 18 months | Score achieved in the Functional Assessment of Cancer Therapy - Breast plus Arm Morbidity (FACT-B+4) questionnaire, a specific validated scale to assess quality of life of women with breast cancer. It comprises 27 items within 5 areas of assessment: physical well-being (7 items), social and family environment (7 items), emotional well-being (7 items), functional well-being (6 items) and worries related to the diagnosis and treatment of the disease (9 items). Each item is scored by means of a Likert scale from 0 to 5, with higher scores representing better results. The total score is obtained by adding the scores for each item, and ranges from a minimum of 0 (worst posible result) to a maximum of 146 (best possible result). |
| Change in tolerance to chemotherapy: number of participants with significant cardiovascular and non-cardiovascular adverse effects throughout the study | Every 3 months during study completion and at the end of the study at an average of 18 months | Significant cardiovascular and non-cardiovascular adverse effects during treatment, threatening life, requiring admission, prolonging hospitalization, being clinically relevant or causing chemotherapy interruptions |
| Change in global functional capacity assessed by conventional ergometry, cardiopulmonary exercise testing (CPET) or the 6-minute walking test (6MWT). | Baseline and at the end of the study at an average of 18 months | Change in functional capacity assessed by conventional ergometry, cardiopulmonary exercise test or the 6-minute walking test (6MWT) (metabolic equivalents: METs or peak oxygen consumption: VO2) \* . \*Due to COVID-19 pandemic, participants' assessment with CPET had to be stopped for safety concerns. In such cases, functional capacity was estimated from the maximum work rate in the 6-minute walking test (6MWT). This test measures the distance that a patient can quickly walk on a flat, hard surface in a period of 6 minutes, which is well correlated with VO2. The 6MWT has been proved to be valid and reliable for functional capacity assessment in the study population. |

| Change in shoulder pain and disability assessed by the SPADI (shoulder pain and disability index (SPADI) questionnaire | Baseline and at the end of the study at an average of 18 months | Score achieved in the SPADI (shoulder pain and disability index) questionnaire. The pain dimension consists of five questions regarding the severity of an individual's pain, functional activities are assessed with eight questions. Each question may be scored from 0 to 10. Verbal anchors for the pain dimension are 'no pain at all' (0) and 'worst pain imaginable' (10) ,and those for the functional activities are 'no difficulty' (0) and 'so difficult it required help' (10). The scores from both dimensions are averaged to produce a total score ranging from 0 (best) to 100 (worst). |
