Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Current primary outcome measures as of 10/01/2019: 1. Cardiotoxicity markers: 1.1. Systolic function (left ventricular ejection fraction), assessed using standard transthoracic echocardiography at the baseline, at the end of treatment and 3 months afterwards 1.2. Myocardial deformation (global longitudinal strain), assessed using standard transthoracic echocardiography at the baseline, at the end of treatment and 3 months afterwards 1.3. Circulating cardiac biomarkers (amino-terminal pro-brain natriuretic peptide), assessed using blood samples at the baseline, 24 hours before the start of each treatment cycle, at the end of treatment and 3 months afterwards 2. Cardiac health outcomes will be assessed at the baseline, at the end of treatment and 3 months afterwards: 2.1. Resting blood pressure, measured in a seated comfortable position using a cardiac monitor 2.2. Resting heart rate, measured in a seated comfortable position using a cardiac monitor 2.3. Resting heart rate variability, measured in a seated comfortable position after at least 5 minutes of rest using a Polar V800 heart rate monitor with a Polar H7 Heart Rate Sensor chest strap. Analysis will be done using Kubios v2 Heart Rate Variability software. 2.4. Heart rate recovery (measured using a cardiac monitor after 30 seconds and 60 seconds after completion of a cardiopulmonary test), defined as the difference between peak heart rate achieved in the cardiopulmonary test and the heart rate at 30 seconds and 60 seconds following this. Previous primary outcome measures: 1. Cardiotoxicity markers: 1.1. Systolic function (left ventricular ejection fraction), assessed using standard transthoracic echocardiography at the baseline, at the end of treatment and 3 months afterwards 1.2. Myocardial deformation (gl | — |
Secondary
| Measure | Time frame |
|---|---|
| All secondary outcomes will be measured at the baseline, at the end of treatment and 3 months afterwards: 1. Functional outcomes: 1.1. Cardiopulmonary capacity (maximum oxygen consumption), evaluated using a Bruce treadmill test with an echocardiogram and continuous analysis of the O2/CO2 exchange 1.2. Upper limb strength (maximum voluntary handgrip strength), assessed using a handgrip dynamometer (6 trials per participant with 3 in each arm) 1.3. Lower limb functionality, assessed using the sit-stand test 2. Health-related quality of life and fatigue, assessed using the European Organization for Research and Treatment in Cancer Quality of Life C-30 (EORTC QLQ-C30) questionnaire 3. Neuropathy-related chemotherapy, assessed using The Functional Assessment of Cancer Therapy/Gynecologic Oncology Group -Neurotoxicity (FACT/GOG-Ntx) Scale) | — |
