Active clinical trials for "Cardiotoxicity"

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. PURPOSE: This clinical trial is studying the effect of chemotherapy on heart function in treating women who have breast cancer with negative axillary lymph nodes and who are undergoing treatment on the SWOG-8897 clinical trial.

Anti-androgenic therapies relying on peripheral and/or central blockade for the treatment of prostate cancer seems to have an impact on the cardio-vascular system. This study investigates reports of cardiovascular toxicities for treatment including Anatomical Therapeutic Chemical (ATC) classification: sex hormones (G03), hypothalamic hormones (H01C) and sex hormones used in treatment of neoplastic diseases (L02) in the French pharmacovigilance database and European Clinical Trials (EudraCT) database.

Anthracycline therapy is well-known for its adverse cardiac effects. Anthracycline-induced cardiotoxicity (AIC) is associated with a poor prognosis; since classical heart failure treatment can potentially reverse cardiac dysfunction at the early stage of cardiac toxicity, early detection of AIC is crucial. Transthoracic echocardiography is recommended for monitoring left ventricular function in patients receiving these molecules. In routine practice, left ventricular systolic function is mainly assessed by the left ventricular ejection fraction (LVEF), measured by two-dimensional echocardiography imaging. However, LVEF depends on the operator's experience and is not sensitive enough to detect subclinical myocardial dysfunction. To overcome these limitations, two-dimensional speckle-tracking imaging has been proposed. This technique allows for a study of global and regional myocardial deformation, especially the longitudinal component, which appears to be the most sensitive one. Several studies have already emphasized the role of global longitudinal strain (GLS) to detect slight alterations in systolic function, especially in the setting of potentially cardiotoxic drugs and even after low to moderate doses of anthracyclines. A recent expert consensus paper strongly recommends GLS assessment for the detection of subclinical left ventricular dysfunction due to anthracycline therapy. Although there is growing evidence that GLS can predict subsequent alterations in LVEF, few data exist on the optimal timing to perform echocardiography. The investigators hypothesized that very early measurement of GLS in the time course of anthracycline therapy could predict subsequent left ventricular systolic dysfunction. The aim of this study was, therefore, to determine whether assessment of GLS after 150 mg/m² of anthracyclines can predict AIC.

Comparing preventive effect of myocardial global longitudinal strain-based cardioprotective stragety (angiotensin receptor blocker prophylaxis) with left ventricular ejection fraction-based strategy in breast cancer patients treated with adjuvant trastuzumab.

The main objective of this randomized controlled trial is to test the association between standard cardiac risk factors, biomarkers and parameters of echocardiography, electrocardiography, and cardiac magnetic resonance imaging, (predictors) and subsequent occurrence, frequency and severity of clinical or subclinical cardiotoxicity (outcome) within and between-groups, before start of chemotherapy, during treatment and at 1, 5, and 10 years after the completion of the chemotherapy among women with early breast cancer.

RATIONALE: Studying samples of blood and tissue in the laboratory from women receiving doxorubicin and trastuzumab for breast cancer may help doctors learn more about changes that occur in DNA and identify biomarkers for increased risk of cardiac effects. PURPOSE: This clinical trial is studying side effects involving the heart in women with breast cancer receiving doxorubicin and trastuzumab.

While sunitinib can be very helpful to treat kidney cancer, these medications can also cause side effects, including heart damage. Studies performed in the past did not look at heart function in detail, so the investigators do not know what happens to the heart when people start sunitinib treatment. The aim of the study is to prospectively study acute effects of sunitinib on heart function, overall fitness and blood markers of heart disease.

The goal of this clinical research study is to learn whether different ways of viewing echocardiogram pictures along with blood tests can help to see heart-related side effects of chemotherapy and trastuzumab earlier than the usual tests.

Cancer therapy can place childhood cancer survivors at increased risk for heart disease which can lead to significant illness or early death. Interventions that occur late in the evolution of treatment-related heart disease are usually ineffective at preventing its progression to death or heart transplant. Our team will work in several research cores to test new imaging and biomarker methods that will lead to earlier detection of heart disease before clinical symptoms develop or it become apparent on standard imaging tests. We will evaluate the importance of genetic differences between individuals in determining who is at greatest risk of developing heart disease as a result of exposure to cardiotoxic agents. We will combine this genetic information with the novel imaging and biomarker methods to predict which children are at particular risk. These vulnerable children can then be targeted by modifying their cancer therapy to reduce their exposure to cardiac toxins, or introducing medications that protect the heart from chemotherapy damage. This team brings together the expertise of clinicians and scientists in pediatric oncology, pediatric and adult cardiology, radiation oncology, genetics, and biostatistics. This is a cross-Canada initiative that will leverage the latest knowledge about cardiac toxicity and create a resource for ongoing research into this important cause of morbidity and mortality in childhood cancer survivors.

The Prefect Pilot Study evaluates the use of the EC approved MyoStrain SENC CMR Imaging System to detect cardiotoxicity from drugs used to treat cancer (e.g. Breast Cancer and Lymphomas).
