Background and study aims
It has been known since the 1970s that chemotherapy with anthracyclines can have adverse side effects on heart function. Between 5 and 30% of all patients treated with anthracyclines develop a decrease in heart function. Nevertheless, anthracyclines play a pivotal role in the treatment of many cancers, such as breast cancers and cancer of the connective tissue (sarcomas). With the fortunate development of increasing numbers of cancer survivors the long-term side effects of chemotherapy become more and more important. The current strategy of assessment of patients for development of heart failure under chemotherapy is mainly based on close observation using ultrasound. There is currently no reliable tool for predicting heart failure under chemotherapy before it actually occurs, or tools for identifying patients at highest risk. MRI is the gold standard for assessment of heart function and has the unique ability to also assess changes in the heart muscle which are known to predict the development of subsequent heart failure. It is thought that chemotherapy with anthracyclines leads to very early changes in the tissue of the heart muscle. These changes may be detectable by MRI and may help to predict the development of heart failure at a much later point in time. Hence, the aim of this study is to assess changes in the heart tissue before and very early (24-48 hours) after the first treatment with anthracyclines using MRI and compare these changes to the development of heart function at the end of chemotherapy treatment (usually after 4-5 months) also assessed by MRI.
Who can participate?
Patients aged at least 18 with sarcoma undergoing chemotherapy with anthracyclines
What does the study involve?
All patients receive three standard MRI scans - one scan before the start of chemotherapy, one 24-48 hours after the first treatment and one 3-4 weeks after the end of chemotherapy. The first and the last MRI scan are part of a normal exam and only the second MRI scan is performed merely due to study participation. Participants also provide blood samples and their heart electrical activity is recorded (electrocardiography [ECG]) at the time of each MRI scan.
What are the benefits and risk of participating?
Benefits include a closer observation of heart function through participation in this study. Extraordinary findings are reported to the referring doctors. One of the three MRI scans is additional and merely performed due to study participation. Since the other two MRI scans are performed anyway, there is no additional burden from a patient's perspective besides the single additional MRI exam.

| Scientific title | Assessment of the predictive value of cardiac MRI in anthracycline-induced cardiomyopathy in sarcoma patients |
| Study acronym | CARETOX-1 |
| Study objectives | Early changes in cardiac tissue morphology assessable by cardiac MRI can predict the development of subsequent cardiomyopathy in sarcoma patients treated with anthracyclines. |
| Ethics approval(s) | Ethics board at Charité University Medicine Berlin, Campus Mitte, 23/09/2014, ref: EA1/262/14 |
| Health condition(s) or problem(s) studied | Anthracycline-induced cardiomyopathy in patients with sarcoma |
| Intervention | Cardiac tissue morphology is assessed in sarcoma patients treated with anthracycline-based chemotherapy using cardiac MRI. Patients receive at least three cardiac MRI scans: before start of chemotherapy (baseline), 24-48 hours after the first treatment and 3-4 weeks after completion of chemotherapy (usually after 4-5 months). Blood analysis is carried out at the time of each MRI scan: NTproBnP, high-sensitive Troponin T, hematocrit, glomerular filtration rate. ECG is also carried out at the time of each MRI scan. |
| Intervention type | Procedure/Surgery |
| Primary outcome measure | Myocardial T1 and T2 times, measured using parametric mapping techniques before start of chemotherapy (baseline), 24-48 hours after the first treatment and 3-4 weeks after completion of chemotherapy (usually after 4-5 months). |
| Secondary outcome measures | Measured before start of chemotherapy (baseline), 24-48 hours after the first treatment and 3-4 weeks after completion of chemotherapy (usually after 4-5 months): 1. Left and right atrial and ventricular size and function, measured in CINE sequences 2. Detection and size of myocardial fibrosis using late gadolinium enhancement techniques 3. Detection of arrhythmia using ECG 4. Laboratory blood analysis parameters (NTproBNP, hematocrit, high sensitive troponin T, glomerular filtration rate) |
