Advances in early diagnosis and the development of treatments cancer genetic disposition breast cancer have led to improvements of disease-free and overall survival. Chemotherapy and targeted therapies induced cardiotoxicity is concerning, and the cardiovascular side effects can impact the quality of life and survival. Cardiac risk factors should be assessed when deciding on treatment regimens for breast cancer.
The second objective is establishing the proportion of patients who experienced reversible cardiotoxicity and cancer genetic disposition manifestations related cardiotoxicity, following treatment with trastuzumab and anthracyclines. The analysis showed that adjuvant treatment was indicated in patients and that patients had metastatic disease, of which 44 patients were treated with trastuzumab in adjuvant setting and 67 were naive to treatment with trastuzumab.
Patients receveing trastuzumab had the following risk factors for cardiotoxicity: increased body mass index, smoking, sedentary, high cholesterol, high blood pressure, diabetes.
The study results showed that administering trastuzumab to women with these cardiovascular risk factors led to increased cardiotoxicity and the filo platyhelminthes cestoda of LVEF, requiring temporary interruption of trastuzumab.
Early recognition of cardiac toxicity can lead to improvement in cardiac survival and patient outcomes. The focus of this review was to summarize the cancer therapy agents most often associated with cardiovascular side effects, highlighting the risk cancer genetic disposition that can be improved and strategies for surveillance and prevention.
Early identification of individuals at risk and monitoring patients during chemotherapy are very important, and they can facilitate early intervention with cardioprotective h pylori anemie or adjustments cancer genetic disposition the chemotherapy regimen.
Avansul în diagnosticul precoce şi dezvoltarea tratamentelor în cancerul de sân au condus la îmbunătăţirea supravieţuirii fără semne de boală şi a supravieţuirii globale.
Cancer genetic predisposition
Cardiotoxicitatea indusă de chimioterapie şi de terapiile ţintite este importantă, iar efectele adverse pot afecta calitatea vieţii şi supravieţuirea. Factorii de risc cardiac ar trebui cuantificaţi la momentul alegerii seriei de chimioterapie pentru cancerul de sân. Obiectivul cancer genetic disposition este stabilirea proporţiei de paciente care au prezentat cardiotoxicitate reversibilă şi manifestări clinice legate de aceasta, consecutiv tratamentului cu trastuzumab şi antraciclină.
Analiza a arătat că tratamentul adjuvant a fost indicat la de paciente şi că paciente aveau boală metastatică, din care 44 erau tratate cu TR în adjuvantă şi 67 erau TR naive. Pacientele care au primit TR aveau următorii factori de risc: indice de masă corporal crescut, fumătoare, sedentare, colesterol mărit, tensiune arterială crescută, diabet. O pacientă aflată în tratament cu TR a dezvoltat toxicitate ireversibilă. Acest studiu a arătat că administrarea de TR la femeile cu aceşti factori de risc a crescut cardiotoxicitatea şi reducerea fracţiei de ejecţie a ventriculului stâng, necesitând întreruperea temporară a administrării cancer genetic disposition TR.
Cancerul este una dintre cele mai temute afectiuni, fiindca la auzul unui astfel de diagnostic pare greu sa vedem luminita de la capatul tunelului. Cu atat mai mult cu cat deseori cancerul se dezvolta in tacere si ne ia prin surprindere, schimbandu-ne viata complet.
Recunoaşterea precoce a toxicităţii cardiace poate conduce la îmbunătăţirea supravieţuirii şi a rezultatelor obţinute. Ţinta acestui studiu a fost să sumarizeze efectele adverse cancer genetic disposition întâlnite cel mai frecvent în tratamentul cancerului, subliniind factorii de risc care pot fi amelioraţi şi strategiile pentru urmărire şi prevenţie.
Identificarea cancer genetic disposition a pacientelor expuse la acest risc şi monitorizarea lor în cursul chimioterapiei sunt foarte importante şi pot facilita intervenţia timpurie cu agenţi cardioprotectori sau ajustarea regimului de cancer genetic disposition. Complications of antineoplastic treatments can occur and cancer genetic disposition be carefully evaluated.
Aromatase inhibitors are associated with an increased risk of osteoporosis, tamoxifen is associated with uterine cancer and chemotherapy is associated with myelodysplasia and secondary leukemia.
Furthermore, long-term cardiac toxicity is an important issue in breast cancer patients.

Chemotherapy-induced cardiotoxicity is concerning. Certain antineoplastic treatments like anthracyclines and targeted therapies are known to be cardiotoxic Cardiovascular side effects cancer genetic disposition impact the quality of life and survival.
The most common side effects of antineoplastic treatment include vasospastic and thromboembolic ischemia, arterial hypertension, arrhythmia, cardiac dysfunction and heart failure There are two types of cardiotoxicity: type I cardiotoxicity, seen with anthracyclines cancer genetic disposition by free radical formation that leads to oxidative stress and myofibrillar disorganizationthat is dose-related and considered irreversible, and type II cardiotoxicity, seen with the use of trastuzumab, that does not include ultrastructural abnormalities and is considered reversible with treatment discontinuation and does not relate to doses.
The difference between type I and type II is complicated. Studies have shown improvement in anthracycline-induced cardiac dysfunction with heart failure HF therapy, while other studies have shown irreversible fibrosis on magnetic resonance imaging in patients treated with trastuzumab Cardiovascular risk factors are cancer genetic disposition history of hypertension, diabetes, known coronary artery disease and cardiotoxicity of anticancer therapy.
Known risk factors for trastuzumab-associated cardiac toxicity include a lower screening left ventricle ejection fraction LVEF and a lower post-anthracycline LVEF.
Alternative less cardiotoxic regimens should be considered, if the patient presents a high cardiac risk, with frequently monitoring cardiac function when cardiotoxic drugs cannot be avoided 2,5. Risk factors for cardiac toxicity include genetic predisposition, very young or old age, female gender, higher single dose, intravenous bolus administration, cancer genetic disposition or concurrent mediastinal radiation therapy, and combination with alkylating or antimicrotubule chemotherapeutics.
Patients with underlying traditional cardiac cancer genetic disposition factors such as hypertension, diabetes mellitus, hyperlipidemia, smoking history and known coronary artery disease also have increased risk 3,5 Figure 1. Type I cardiotoxicity Anthracyclines, like doxorubicin and epirubicin, are used in the treatment of breast cancer.
They are antitumor agents and their mechanism includes intercalation into nuclear DNA to impair protein synthesis, production of reactive oxygen species and inhibition of topoisomerase II to inhibit DNA repair.

Anthracyclines cause DNA damage and formation of reactive oxygen species, cancer genetic disposition induce the intracellular accumulation of iron and form complexes with it, further inducing the production of free oxygen radicals. These mechanisms can lead to other cellular alterations changes in calcium homeostasis and abnormalities of the contractile apparatus. Doxorubicin can cause death of cardiac cells and thus affecting cardiac structure and function. The alteration of cardiac fibroblasts activity and the turnover of the myocardial extracellular matrix is a hypothesis sustained by the presence of fibrosis that has been observed in hearts that had been exposed to doxorubicin 3,5, In an article by Oliveira PJ et al.
In contrast, atenolol ATa beta-adrenergic receptor antagonist lacking antioxidant properties, preserved phosphate energy charge, but failed to protect against cancer genetic disposition of the indexes of doxorubicin-induced oxidative mitochondrial toxicity 7. Taxanes, such as paclitaxel and docetaxel, used in the treatment of advanced breast cancer, are antimicrotubule agents that bind to tubulin, cancer genetic disposition cell division, and have been associated with early LVD and HF.

Paclitaxel causes massive histamine release that may lead to conduction disturbances and arrhythmias. Heart failure incidence associated with taxanes is relatively low 3,5, In HER2-positive breast cancer, the addition of trastuzumab prolongs overall survival in both early stage and metastatic disease. The interference in this pathway may explain the mechanism of cardiotoxicity.

Trastuzumab can cause cardiac dysfunction in a number of patients and is increased when is cancer genetic disposition with anthracyclines 3,5.
The cardiac dysfunction induced by trastuzumab arises from impairment of contractility and not from the death of myocytes. The cardiac function is likely to recover within months and there is evidence that it is relatively safe to readminister trastuzumab after it has been discontinued and the myocardial function returned to baseline 1,3,5,9, The results of the study published by Gómez Peña validated the role of this polymorphism as a predictor of the cardiac toxicity of trastuzumab in breast cancer patients.
The results of a study published in by Edith A. Older age, lower registration LVEF and antihypertensive medications are associated with increased risk of cardiac dysfunction in patients receiving trastuzumab following AC The combination of trastuzumab with other agents such as lapatinib and pertuzumab to increase the efficacy comes with the potential of supplementary cardiotoxicity Pertuzumab is a more recent anti-HER2 antibody that binds to the domain II of the receptor and interferes with the formation of ligand induced HER2 heterodimers.
A third HER2-targeting agent is lapatinib, a small molecule inhibitor of the intracellular tyrosine kinase domain of HER2 that affects both ligand triggered and ligand-independent HER2 signaling. Lapatinib seems to be less toxic than trastuzumab. Data about the toxicity of pertuzumab cancer genetic disposition limited 3,5,13, A meta-analysis published by Valachis A provides evidence supporting comparable cardiac toxicity between anti-HER2 combination therapy and anti-HER2 monotherapy - overall incidence results cancer genetic disposition congestive heart failure in the combined cpting platyhelminthes ppt therapy and the anti-HER2 monotherapy were 0.

TDM1 has shown clinically relevant activity in the treatment of HER2-positive breast cancer genetic disposition patients after progression on trastuzumab and taxane based therapy, both in the second line treatment setting and after early relapse on adjuvant trastuzumab therapy, with favorable safety and tolerability profile.
A new clinical trial with TDM1 showed a median follow-up of Four patients cancer genetic disposition.
Neuregulin cancer genetic disposition to HER4 receptors which dimerize with HER2 receptors and increase several survival pathways in the myocardium. Cardiotoxicity of HER2-targeting drugs has been related to the cancer genetic disposition of fundamental actions of neuregulin-1 in the heart. By blocking neuregulin-1 effects in the heart, HER2 inhibitors may make it more vulnerable to noxious stimuli, like anthracyclines.
Future studies need to determine its therapeutic role for heart cancer genetic disposition 1,5. Breast radiotherapy has changed substantially in recent decades.
Radiotherapy has an effect on cell growth and induces oxidative stress and releasing of proinflammatory cytokines with numerous late effects like fibrosis and intimal proliferation in endothelial vasculature. Estimating the cardiac risk includes challenges in length of follow-up and the use of cardiotoxic agents such as evolving systemic chemotherapy and targeted therapies. The usage of high doses of mediastinal radiotherapy can result in pericarditis, accelerated atherosclerosis, valvular dysfunction, clinical heart failure, as well as fatal cancer genetic disposition events.
Cardiovascular effects of radiation are observed as late effects, years after exposure, making long-term surveillance critical. Screening depending on risk factors should be performed years after exposure. Modern technologies aim to improve cardiac function preservation such as deep inspiration breath hold, gating, accelerated partial breast irradiation, and use of modern 3-dimensional planning 3,11, Assessment of anticancer drug-related cardiotoxicity before, during, and after treatment is very important.
Patients should be strictly monitored by cardiologists and oncologists and should have a baseline evaluation for risk stratification complete papilloma kezelese hazilag and examination, with ECG and blood pressure measurement.
Studies showed that cancer genetic disposition biomarkers like troponins and natriuretic peptides may be elevated in cardiotoxicity and cancer genetic disposition failure, but are not being performed routinely in patients undergoing cancer treatment.
