Filter by:Neoplasia is the main cause of general death in the Brazilian population. In 2016, they were responsible for approximately 211,343 (16%) deaths, followed by cardiovascular diseases (12.6%). Despite the high mortality rate of neoplasia, oncological treatment have advanced substantially in recent decades improving the prognosis of patients. However, growing evidence suggest that some oncological agents may induce significant toxicity that may play a major role in the quality of life, morbidity and mortality. The cardiovascular system is often negatively affected with cancer therapy, predisposing several patients to stop appropriate treatments or to have cardiovascular events related to the cardiotoxicity. The most typical manifestation of cardiotoxicity and related consequences (heart failure) are related to the use of anthracyclines. Anthracyclines are part of the chemotherapy regimen for solid tumors and hematological neoplasms in children and adults, and are associated with an increase in life expectancy. Carvedilol is an α and β-blocker that also has antioxidant properties. Preliminary studies have shown that carvedilol and its metabolites prevent lipid peroxidation, inhibit the formation and inactivate free radicals, in addition to preventing the depletion of endogenous antioxidants, such as vitamin E. These effects would potentially prevent anthracycline injury but definitive evidence is still needed. This is a multi-center, double-blind, randomized, placebo-controlled study that aims to establish the efficacy of carvedilol for the primary prevention of left ventricular systolic dysfunction in cancer patients obtained with anthracycline chemotherapy, in different schedules and doses.
Management of patients with lymphoma is based on the administration of a chemotherapy containing anthracyclines (ATC), and allows cure rates of 65% to 80% at 5 years. The administration of ATCs can lead to an increase in the risk of the Left Ventricular Systolic dysfunction (LVSD) which ranges from 6 to 15% at 1 year, and of heart failure from which impact at 3.5 years can reach 5%. The major issue in the management of this toxicity is the early identification of this population for monitoring and prevention. No pharmacological intervention strategy is currently recommended. According to the recommendations of the European Society of Cardiology, this identification is based on the measurement of the left ventricular ejection fraction (LVEF) and the overall longitudinal strain (SLG) before and after the last administration of ATC ( at D84 or D126, depending on the duration of the chemotherapy protocol). Recent studies have evaluated the diagnostic performance of earlier strategies highlighting the benefit of SLG measured after 150 mg / m2 of ATC (D42). However, the tools are lacking to detect these patients as close as possible to the onset of ATC, a necessary condition for effective secondary prevention. The hypothesis is that an early assessment of myocardial binding of 18F-FDG, analyzed during the first routine PET / CT scan as part of the assessment of the response to chemotherapy (D42) should verify a population at risk of developing LVSD at 1 year.
The main aim is to validate non-gated 5-min computed tomography myocardial relative enhancement (CT-MRE), which can be readily estimated via contrast-enhanced non-gated chest CT, as a tool for estimating myocardial extracellular volume (ECV) using cardiac magnetic resonance (CMR)-derived ECV as a reference standard in a consecutive series of patients scheduled for cardiac CT. A secondary explorative aim is to evaluate the presence and extent of possible myocardial alterations in those patients enrolled in the VALETUDO study who have been infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).
Despite the growing interest in investigating how the radiotherapy (RT) dose to anatomical substructures of the heart links to survival, the heart substructures at risk remain poorly defined. They are not delineated routinely as part of the RT planning process and there is no consensus on their dose constrains. With improving prognosis for non-small cell lung cancer (NSCLC) patients, the evidence relating irradiation of the heart to excess mortality has begun to accumulate. The study aims to evaluate subclinical cardiac dysfunction in consecutive NSCLC patients treated with definitive RT and to investigate the predictive value of the heart substructures dosimetric parameters for subclinical and overt cardiac toxicity as assessed using traditional and speckle tracking echocardiography (STE). The study will also investigate whether subclinical alterations detected by echocardiography with strain imaging may serve as a marker for future clinical dysfunctions.
This study will explore why some multiple myeloma patients who receive carfilzomib (an anti-cancer medication) experience shortness of breath while others do not. The purpose of this research is to gather information on the effectiveness of the EndoPAT device, which is FDA-approved to assess the health of a patient's blood vessels. These assessments will help doctors leading the study determine the reasons why patients may develop shortness of breath (dyspnea) when being treated with carfilzomib and ways to better prevent this shortness of breath.
This is a multicentre non-randomized phase II study of proton beam radiotherapy in patients with thymic epithelial tumours (i.e. thymoma and thymic carcinoma) in the post-operative setting or in inoperable patients with localized disease. Patients not willing or for any reason unsuitable to undergo proton treatment will be asked to participate in a follow-up assessment after the regular photon treatment in the same manner as the included patients. Primary endpoints are:Toxicity (e.g. cardiac and pulmonary toxicity) and Local control at 5 year Secondary endpoints: PFS, Overall survival, Quality of life, measured by EORTC QLQ 30 + LC 13 and relapse pattern
To assess the role of myocardial oedema on CMR (T2 mapping) after radiation therapy and cardiotoxic systemic therapy in predicting the incidence of cardiotoxicity, defined as by consensus guidelines* (decline of LVEF ≥10% points with a final LVEF <53%) measured on CMR and ECHO over the time window of 12 months from the end of radiation therapy.
The purpose of this study is to investigate the risk factors and mechanisms of cardiotoxicity following thoracic radiotherapy and to provide insights in preventing radiation-related cardiotoxicity. -Condition or disease : Thoracic irradiation -Intervention/treatment : Cardiac evaluation, Blood sampling
The main goal of the current research program is to examine the use of nutraceuticals, in particular flaxseed (FLX), in the prevention of Doxorubicin and Trastuzumab (DOX+TRZ) mediated cardiotoxicity in the clinical setting. As Manitoba continues to be one of the top FLX producers in the world, there is an increasing public awareness of the importance of the consumption of this whole grain commodity in the prevention of cancer and cardiovascular disease. In North America, approximately 1 in 8 women will develop breast cancer and will receive treatment with DOX+TRZ. Although women with breast cancer are at risk of developing heart failure due to chemotherapy, FLX has the capacity to prevent this outcome. The purpose of the CANFLAX study is to establish FLX "milk" as an effective method in preventing heart failure in women with breast cancer.
The present study aims to investigate the chronic effect of treatment with doxorubicin and cyclophosphamide on neurovascular control and blood pressure in women undergoing adjuvant treatment for breast cancer.
