Filter by:The main hypothesis being tested is that magnetic resonance imaging and serologic biomarkers of apoptosis and extracellular matrix remodeling will precede echocardiographic indices of systolic and diastolic function among childhood cancer survivors treated with anthracyclines thus allowing evaluation of new therapies to prevent and manage heart failure in these patients.
Trastuzumab prolongs survival in patients with human epidermal growth factor receptor type 2-positive breast cancer. Sequential left ventricular (LV) ejection fraction (EF) assessment has been mandated to detect myocardial dysfunction because of the risk of heart failure with this treatment. Myocardial deformation imaging is a sensitive means of detecting LV dysfunction, but this technique has not been evaluated in patients treated with trastuzumab. The aim of this study was to investigate whether changes in tissue deformation, assessed by myocardial strain and strain rate (SR), are able to identify LV dysfunction earlier than conventional echocardiographic measures in patients treated with trastuzumab.
The main objective of this study is to compare the proportions of late enhancement in patients with Left ventricular (LV) dysfunction as Herceptin ® and in a control group consisting of patients who did not have LV dysfunction after 6 months under the same treatment.
Rationale: Recently, sunitinib (a tyrosine kinase inhibitor that is used for treatment of metastatic renal carcinoma and gastrointestinal stroma tumors) has been associated with development of heart failure, possibly by off-target inhibition of AMP-protein kinase. The investigators hypothesize that sunitinib reduces the contractile ability of myocardium and the tolerance against ischemia-reperfusion and that activators of AMP-protein kinase such as atorvastatin and AICAR reverse this unwanted effect of sunitinib. Objectives: The primary objective of the study is to investigate the effect of sunitinib on ex-vivo atrial contractile force in absence and presence of ischemia-reperfusion. A secondary objective is to explore if atorvastatin or AICAR prevent sunitinib-induced deterioration of contractile function of human atrial trabeculas. Study design: Lab
It is now accepted that the anticancer properties of anthracyclines were allowed in many malignancies improve the prognosis of affected populations. However, the cardiotoxicity of anthracyclines is responsible for an interruption of this treatment by alteration of potentially irreversible myocardial contraction and high mortality. An earlier detection of adverse myocardial anthracycline chemotherapy would allow the adaptation of the regimen by reducing the number of interruptions of antitumor and strengthening monitoring. Optimizing the therapeutic antitumor and generate an increase in survival of patients treated.
The objective of this study is to define the clinical significance of mechanistic biomarkers (including Neuregulin-1Beta) and novel echocardiographic measures of cardiac function in predicting the incident risk of cancer therapy cardiotoxicity.
The goal of this clinical research study is to learn if certain biomarker testing on blood samples can help to detect heart damage that may occur during chemotherapy. Biomarkers are chemical "markers" found in the blood that may be related to heart function. High levels of these markers may be linked with heart problems such as heart damage.
Herceptin has shown significant improvement in breast cancer therapy and improved survival of patients over-expressing the HER-2 protein by 50%. However, Herceptin has shown to negatively affect the heart, and frequent heart monitoring with multiple gated acquisition (MUGA) scans is required. MUGA scans use radiation and are not very accurate. This study will use cardiac magnetic resonance images (CMRs) to evaluate heart function and compare to MUGA scans in patients receiving Herceptin for early-stage breast cancer. In addition, novel biomarkers will also be assessed at the same time to help identify possible patients at risk for developing heart toxicities.
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.
RATIONALE: Lisinopril or Coreg CR®, may help reduce side effects caused by trastuzumab. It is not yet known whether lisinopril or Coreg CR® are more effective than a placebo in reducing side effects caused by trastuzumab. PURPOSE: This phase II trial is studying lisinopril and Coreg CR® to see how well they work compared with a placebo in reducing side effects in patients with HER2-positive breast cancer receiving trastuzumab.
