Hematopoietic stem cell transplantation is an important method for the treatment of hematological diseases and cyclophosphamide is a commonly used chemotherapeutic agent for transplant pretreatment. The incidence of severe cardiovascular events after high-dose cyclophosphamide exposure ranges from 7% to 28% with mortality from 11% to 43%. Thus, an non-invasive, sensitive and reliable method in detecting cardiac function is significant to balance the cardiac risk and the potential cancer treatment benefits. In previous studies, we demonstrated that strain values analyzed by speckle tracking echocardiography decreased significantly after high-dose cyclophosphamide exposure, even though left ventricular ejection fraction remained stable and within normal range. We follow up the hematopoietic cell transplantation patients with cyclophosphamide: to analyze the cut-off values of the parameters of speckle tracking multilayer analysis in predicting early cardiotoxicity induced by cyclophosphamide; to detect the cut-off values of the plasma miRNAs levels in predicting early cardiotoxicity induced by anthracycline. The purpose of our study is to find out non-invasive, reliable and sensitive echocardiographic parameters and plasma biomarkers for early detection and prediction cyclophosphamide -induced cardiac toxicity and to be helpful to target patients at high risk of cardiotoxicity, who could benefit from closer monitoring or earlier initiation of cardioprotective therapy.
This is an observational study for patients with prostate cancer that will be treated with Androgen Deprivation Therapy. The study will help the investigators learn more about how these medications affect the heart and how those effects relate to patients' medical history and social determinants of health (such as race, gender identity, education, occupation, access to health services and economic resources). Patients on this study will have echocardiograms, blood draws, and answer questions about their symptoms and activity level. Patients will be followed on this study for up to 5 years.
This is an observational study for patients with breast cancer that will be treated with doxorubicin (Adriamycin) and/or trastuzumab (Herceptin). The study will help the investigators learn more about how these medications affect the heart and how those effects relate to patients' medical history and social determinants of health (such as race, gender identity, education, occupation, access to health services and economic resources). Patients on this study will have echocardiograms, blood draws, and answer questions about their symptoms and activity level. Patients will be followed on this study for up to 15 years.
The purpose of this study is to find out how much oxygen is used during a cardiopulmonary exercise test (CPET) in women who have mild cardiotoxicity after standard treatment for HER2-positive breast cancer, and to see whether the results of this test can be used to predict how well participants' heart and lungs will work if they continue to receive this kind of treatment.
Pediatric, adolescent and young adult cancer survivors (PAYA-CS) are at higher risk of cardiovascular (CV) morbidity and mortality. This is a consequence of prior cancer-related therapies that have the potential of producing cardiac dysfunction, reducing cardiorespiratory fitness (reduced VO2peak) and psychosocial morbidities (i.e., anxiety and depression). A reduction of physical activity levels can evoke functional limitations resulting in a vicious cycle of reduced exercise tolerance and physical deterioration. To date, there is limited evidence on the use of non-pharmacological strategies such as Cardio-Oncology Rehabilitation (CORE) including structured exercise, behavioural support and risk factor management to improve the outcomes of this underserved population. The HIMALAYAS study is a randomized controlled trial designed to evaluate the impact of a CORE intervention (consisting of six-months home and onsite-based structured moderate to high-intensity aerobic exercise training and CVD risk factor management) on CV and psychosocial health, and the cardiovascular disease risk in PAYA-CS with mild heart dysfunction (stage B heart failure) compared to standard of care (i.e. providing guidance on the current exercise recommendations for cancer survivors). The primary objective of the HIMALAYAS study is to determine whether a six-month supervised CORE intervention, consisting of individualized moderate to high-intensity aerobic exercise training, CVD risk factor modification and enhanced online behavioral support, improves cardiorespiratory fitness (VO2peak; primary outcome), cardiac function, CVD risk factors and biomarkers, and patient-reported outcomes (PROs) at six- months follow-up compared to standard of care (CON) in PAYA-CS with stage B heart failure. The secondary objective is to assess the same outcomes at 12- and 24-months follow-up. We will recruit 336 patients across 5 sites in Canada and upto 134 patients at UHN in 3 years and conclude in 6 years.
The introduction of trastuzumab for the treatment of patients with human epidermal growth factor receptor 2 (HER2) positive breast cancer has had a major impact upon cancer outcomes. However, cardiac toxicity remains a substantial concern. Conventionally, this toxicity has been considered as a transient and reversible phenomenon occurring in the immediate peri-treatment period in around 20% of patients. Current guidelines recommend monitoring heart function during treatment and at completion. Recent registry data suggest that trastuzumab-related cardiotoxicity may also manifest in the longer-term. The nature and longer-term prevalence of left ventricular dysfunction with HER2 positive breast cancer treated with trastuzumab is unclear. The aim of this project is to define the prevalence of left ventricular dysfunction late after completion of trastuzumab therapy.
Explore the effects of anti-VEGF targeted drugs on blood pressure and endothelial function in cancer patients.
According to the existing clinical data in our hospital, retrospective study was conducted to screen the risk factors with predictive value for TRC(trastuzumab-related cardiotoxicity) risk, and to construct the risk prediction model for TRC.
By dynamically observing the changes of echocardiogram and biomarkers in breast cancer patients using trastuzumab, evaluate the effect of trastuzumab on cardiac function; determine the sensitivity of echocardiography and biomarker indicators And specificity, explore effective and specific early warning indicators, and provide technical support for the evaluation of the cardiac safety of anti-tumor drugs.
