Filter by:Anthracycline (AC) chemotherapy has substantially reduced the mortality rate from several common cancers globally. Unfortunately, AC treatment is associated with up to 19% risk of heart failure (HF). Current standard of care for preventing AC induced HF (AIHF) is cardiac surveillance followed by initiation of treatment once HF is diagnosed. With this approach 89% of patients fail to recover heart function and 46% will experience adverse cardiac events. Therefore there is a need for effective preventive therapy to reduce the risk of AIHF. Based on small human studies, animal studies, and our own pilot data, statins are an ideal class of drug for this purpose. We will conduct a pilot double blinded, placebo controlled, randomized controlled trial to assess whether pre-treatment with statins before AC can prevent heart dysfunction. Eligible patients with cardiovascular risk factors scheduled to receive AC will be recruited. They will be randomized to statin therapy or placebo and followed until the end of cancer treatment. Primary outcome is the difference in cardiac MRI-determined left ventricular ejection fraction between pre-AC and end of treatment.
Survival rates of children with cancers have improved significantly in the recent few decades. Nonetheless, the side effect of this class of drugs on heart function remains to be an issue of concern. Exploration of new strategies to protect the heart in the long term is therefore of paramount importance in children undergoing treatment of cancers. Previous cardioprotective interventions hav focused on changing the formulation or rate of administration of anthracyclines but with no observable benefits. While dexrazoxane, an iron chelator, has shown to reduce cardiotoxic outcomes, there remains worries of an association between dexrazoxane use and an increased risk of developing secondary malignancies. Recently, the clinical application of remote ischaemic preconditioning (RIPC) as a non-invasive and an easily applicable non-pharmacological myocardial protective intervention has gained increasing interest. Remote ischaemic preconditioning is the phenomenon in which brief episodes of reversible ischaemia and reperfusion applied to one vascular bed render resistance to ischaemia reperfusion injury of tissues and organs distant away. It can be achieved by repeated 5-minute cycles of inflation and deflation of blood pressure cuff placed over the arm or leg to induce limb ischaemia and reperfusion injury. It is noteworthy that anthracycline cardiotoxicity and myocardial reperfusion injury occur through similar pathways. Hence, the investigators hypothesize that RIPC may reduce myocardial injury in children receiving anthracycline chemotherapy for childhood malignancies. The proposed study aims to conduct a parallel-group blinded randomized controlled trial study to investigate whether RIPC may reduce heart damage in childhood cancer patients undergoing anthracycline-based treatment, and to determine the effect of RIPC on the changes in levels of cardiac troponin T, and on the occurrence of clinical cardiovascular events and echocardiographic indices.
This is a pilot prospective cohort study, in adult female subjects 18-85 years old with a diagnosis of invasive breast cancer who are planned for anthracycline-inclusive chemotherapy and followed up for a time period of 6 months post completion of anthracycline chemotherapy. They will participate in blood and imaging tests with a goal of determining the best method for predicting the occurrence of cardiotoxicity in this subpopulation.
Breast cancer is the leading cause of cancer among Canadian women with nearly 26,000 new cases diagnosed each year. Fortunately, advancements in diagnostic tools and curative treatments have significantly improved overall survival. However, the development of cardiac toxicity (including asymptomatic and symptomatic heart failure) associated with use of anthracycline containing chemotherapy and targeted therapies including trastuzumab limits improvements in survival for women with breast cancer. Cardiac toxicity is a life threatening complication that leads to reduced physical functioning and quality of life. The increased risk is associated with shared risk factors among cancer and heart failure and the direct influence of cancer therapy on the cardiovascular system. Cardiac rehabilitation (CR) (including exercise training and education/counselling) has been shown to improve health outcomes, reduce heart failure related hospitalizations and modestly improve mortality among individuals with non-treatment related heart failure and may benefit women with breast cancer and treatment related cardiac toxicity (BC-CT). Therefore, this single centre, randomized control trial aims to determine if participation in an exercise based CR program can improve cardiorespiratory fitness, cardiovascular function/structure and health, and quality of life among women with BC-CT.
To evaluate cardiac MRI and/or serum biomarkers for detecting cardiac cardiac toxicity in children who received anthracycline based chemotherapy (ABC).
This research study will test whether atorvastatin, a drug commonly prescribed for reducing cholesterol levels, can protect the heart during chemotherapy with doxorubicin. Atorvastatin is from a family of medications that are commonly called "statins"
This trial is to explore the optimal strategies for guaranteeing the cardiac safety of breast cancer patients following adjuvant radiotherapy in the modern era of multidisciplinary treatment.
All patients enrolled in the study will have to be treated with a chemo immunotherapy scheme R-CHOP with doxorubicin, with doxorubicin analogue or non pegylated liposomal anthracycline (R-COMP; Sec. 648 DM) administered every 21 days for 6 cycles. In unfavourable patients (stage II-IV) are allowed 2 additional cycles of rituximab at the end of the 6 cycles of R-CHOP.
Sulfadoxine-pyrimethamine (SP) is currently recommended by the World Health Organization for use as intermittent preventive treatment against malaria in pregnancy (IPTp) in areas of moderate to high malaria transmission. However, in some locales malaria parasites have lost sensitivity to SP, compromising its protective effect. Dihydroartemisinin-piperaquine (DP) is a candidate replacement for SP. This trial is designed to confirm the cardio-safety of DP compared to SP amongst pregnant women in Tanzania.
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.
