Chemotherapy cardiotoxicity: cardioprotective drugs and early identification of cardiac dysfunction.
2016
Background: Chemotherapy cardiotoxicity is an emerging problem and it is very important to prevent cardiac dysfunction caused by anticancer drugs. The aim of this study was to assess the alterations of the cardiac function induced by chemotherapy in a follow-up of 2 years and to evaluate the cardioprotective role of angiotensin-converting enzyme inhibitors (ACEIs) in the prevention of cardiac dysfunction. Methods: A prospective study was carried out using patients with breast cancer (85 women; median age 57W12years) and other inclusion and exclusion criteria. On the basis of treatment, patients were divided into six groups: fluorouracil-epirubicincyclophosphamide, FEC (group A); FEC and tra…
Dystrophin-deficiency increases the susceptibility to doxorubicin-induced cardiotoxicity
2007
Background and aim: The clinical use of doxorubicin (DOX) and other anthracyclines is limited by a dosage-dependent cardiotoxicity, which can lead to cardiomyopathy. The role of the individual genetic makeup in this disorder is poorly understood. Alterations in genes encoding cardiac cytoskeleton or sarcolemma proteins may increase the susceptibility to doxorubicin-related cardiotoxicity. Methods: Female dystrophin-deficient mice (MDX) and age-matched wild-type mice underwent chronic treatment with doxorubicin. Cardiac function and tissue damage were assessed by echocardiography and histopathology, respectively. Gene expression changes were investigated using microarrays. Results: DOX treat…
Early detection of myocardial damage: A multimodality approach
2019
Cardiovascular diseases are possible complications of antineoplastic treatment and may lead to premature morbidity and mortality among cancer survivors. A symptom-based follow-up is ineffective, and there are growing evidences that early detection of myocardial damage in patients treated with antineoplastic drugs is the key point to prevent the occurrence of damage and improve the prognosis of these patients. Different techniques have been proposed to monitor cardiac function in oncologic patients such as cardiac imaging (echocardiography, nuclear imaging, and cardiac magnetic resonance) and biomarkers (troponin and natriuretic peptides). The European Association of Cardiovascular Imaging/A…
Cardiovascular imaging in the diagnosis and monitoring of cardiotoxicity: Role of echocardiography
2016
The evaluation by cardiovascular imaging of chemotherapy patients became a central topic in the last several years. The use of drugs for the treatment of cancers increased, and new molecules and protocols were developed to improve outcomes in these patients. Although, these novel approaches also produced a progressive increase in side effects, particularly myocardial dysfunction. Imaging of the heart was highly accurate in the early diagnosis of cancer therapeutics related-cardiac dysfunction. Echocardiography is the first-line method to assess ventricular function alterations, and it is required to satisfy the need for an early, easy and accurate diagnosis to stratify the risk of heart fai…
Inorganic Nitrate Therapy Improves Doxorubicin-Induced Cardiomyopathy
2011
The anthracycline doxorubicin (DOX) is a potent and effective antineoplastic antibiotic agent widely used in the treatment of a broad range of forms of cancer. The clinical use of DOX is limited by cardiotoxicity, which increases dose dependently and may lead to dilated cardiomyopathy and clinical
Cardio-oncology in multiple myeloma: is it time for a specific focus?
2017
It has been known for some time that some oncologic drugs can cause heart damage. The term ‘cardiotoxicity’ just refers to the presence of a cardiac event during therapy or at least related to ther...
From molecular mechanisms to clinical management of antineoplastic drug-induced cardiovascular toxicity: A translational overview
2019
Significance: Antineoplastic therapies have significantly improved the prognosis of oncology patients. However, these treatments can bring to a higher incidence of side-effects, including the worrying cardiovascular toxicity (CTX). Recent Advances: Substantial evidence indicates multiple mechanisms of CTX, with redox mechanisms playing a key role. Recent data singled out mitochondria as key targets for antineoplastic drug-induced CTX; understanding the underlying mechanisms is, therefore, crucial for effective cardioprotection, without compromising the efficacy of anti-cancer treatments. Critical Issues: CTX can occur within a few days or many years after treatment. Type I CTX is associated…
Timely recognition of cardiovascular toxicity by anticancer agents: a common objective of the pharmacologist, oncologist and cardiologist.
2011
Both conventional and new anticancer drugs can frequently cause adverse cardiovascular effects, which can span from subclinical abnormalities to serious life-threatening and sometimes fatal events. This review examines the principal basic and clinical elements that may be of profit to identify, prevent and treat such toxicities. Clearly, the accomplishment of such objectives requires the strong commitment and cooperation of different professional figures including, but not limited to, pharmacologists, oncologists and cardiologists. The aspect of anticancer drug cardiotoxicity seems to be somehow underestimated, mainly due to inadequate reporting of adverse reactions from oncology drugs in t…
Cardiovascular Damage Induced by Radiotherapy
2018
Radiotherapy is a fundamental therapeutic aid that in recent years has contributed significantly to improve the prognosis of cancer patients. Despite its great effectiveness, it can cause a wide spectrum of toxic effects. Among these, cardiovascular toxicity is very relevant, and it can occur even many years after the termination of treatment. The concomitant use of radiotherapy with other antineoplastic drugs, including new-generation tyrosine-kinase inhibitors or immunotherapy, can enhance its cardiotoxic effects. It is fundamental to know the cardiovascular toxic effects that are potentially linked to radiotherapy (RIHD: radiation-induced heart damage), to monitor patients who underwent …
Clinical Practice Guideline on Melanoma From the Spanish Academy of Dermatology and Venereology (AEDV)
2020
El diagnóstico y tratamiento del melanoma en atención especializada es un campo en el que se han producido numerosos cambios. El objetivo de esta guía es ofrecer a los dermatólogos españoles una referencia para resolver las dudas clínicas más frecuentes basándose en la evidencia actual. Para la realización de esta guía se escogió a miembros del Grupo Español de Dermato-Oncología y Cirugía con experiencia en el tratamiento de estos tumores y con interés en participar en la elaboración de la guía. Se hizo una adaptación de las guías de práctica clínica existentes mediante el método ADAPTE: inicialmente se resumió el proceso de atención y se elaboraron las preguntas clínicas relevantes. Se sel…
