Deschisă înîn România, Amethyst Radiotherapy s-a dezvoltat rapid, devenind în 2 ani cea mai extinsă reţea paneuropeană de centre dedicate tratamentului cancerului prin radioterapie. În prezent, reţeaua Amethyst are 6 clinici deschise în 4 ţări, cumulând 10 acceleratoare liniare şi 4 echipamente de brahiterapie. La nivel european, printre cele mai frecvente tipuri de cancer tratate în cadrul Amethyst Radiotherapy se numără cancerul de sân, urmat de cel de prostată şi plămâni.
În România, la acestea se adaugă tumorile la nivelul colului uterin şi ORL. Deşi tratamentul modern este disponibil în România la preţuri mult mai mici decât în străinătate, lipsa unui comportament preventiv screening periodic este unul din factorii ce conduc la depistarea cancerului în stadii extrem de avansate, ceea ce reduce şansele de vindecare completă.

Gabriel Doru Ghizdăvescu medic primar Oncologie Medicală, şef Secţie Oncologie, Spitalul Schuller Ploieşti Abstract Rezumat Anticancer therapy is now more effective than ever before, but with the price of important side efects, chief amongst these being cardiovascular side effects.
Prevenirea cancerului prin intermediul unor programe de screening
Over the last years, the significance of the cardiac toxicity of anticancer treatment has markedly increased due to improvements in patient survival, aging of the population including cancer patients and the introduction of new anticancer drugs with unique toxicities.
Following cancer treatment in many patients the risk of cardiovascular death may be higher than the actual risk of tumor recurrence. Cardiotoxicity is defined as the entirety of significant cardiovascular side effects secondary to anticancer treatment, characterised by the decrease in LVEF, responsible for increased morbidity and mortality.
The most frequent and serious side effect is heart failure with ventricular systolic dysfunction.
Other important toxic effects are hypertension, thromboembolic disease, pericardial disease, arrhythmias and myocardial ischemia. Cardiotoxicity can be classified as non-reversible that leads to progressive systolic heart failure and is most typically caused by anthracyclines and reversible cardiac dysfunction that resolves for most patients over time by interrupting human papillomavirus and liver cancer therapy and administering specific cardiac treatment the best known anticancer human papillomavirus and liver cancer that causes reversible cardiotoxicity is trastuzumab.
All patients undergoing chemotherapy should have prior careful clinic evaluation and assessment of CV risk factors or comorbidities, as well as routine ECG and baseline Doppler echocardiogram.
Keywords: anticancer therapy, cardiotoxicity, cardiovascular side effects Terapia antineoplazică este acum mai eficace decât oricând, dar cu preţul unor efecte adverse importante, pe primul loc situându-se efectele secundare cardiovasculare.
Semnificaţia cardiotoxicităţii este tot mai importantă datorită creşterii supravieţuirii globale inclusiv a pacienţilor neoplaziciapariţiei cancerului la vârste înaintate şi datorită introducerii unor noi agenţi terapeutici cu toxicităţi cardiovasculare importante, ajungându-se în situaţia în care la mulţi pacienţi riscul de deces prin boli cardiovasculare să fie mai mare decât riscul de recurenţă a cancerului.
Cardiotoxicitatea se defineşte prin totalitatea efectelor adverse cardiovasculare semnificative secundare tratamentului antineoplazic, caracterizate de scăderea FEVS, responsabile de morbiditate și mortalitate.
Cel mai important efect advers îl reprezintă insuficienţa cardiacă congestivă.
Alte efecte secundare importante sunt reprezentate de HTA, boala tromboembolică, pericardita, aritmiile, ischemia miocardică. Din punct de vedere al tipului de cardiotoxicitate, se întâlnesc tipul ireversibil cu progresie spre insuficienţă cardiacă ge nerată în principal de antracicline şi tipul reversibil în care disfuncţia cardiacă se remite prin întreruperea administrării terapiei antineoplazice şi administrarea de tratament specific cardiologic cel mai cunoscut agent antineoplazic care produce cardiotoxicitate reversibilă fiind trastuzumab.
În practică, este necesară evaluarea clinică a pacientului şi a factorilor de risc cardiovasculari la prezentare şi pe parcursul tratamentului antineoplazic, precum şi evaluarea paraclinică prin efectuarea de rutină a electrocardiogramei şi a ecocardiografiei Doppler, cu determinarea FEVS.
Tratamentul efectelor secundare cardiovasculare trebuie să fie rezultatul eforturilor medicului oncolog şi ale medicului cardiolog, care trebuie să desfăşoare o muncă în echipă, având ca obiectiv final îmbunătăţirea speranţei de viaţă a pacientului, astfel încât să putem trata cancerul protejând inima sau să se trateze inima permiţându-i pacientului cel mai bun tratament oncologic posibil.
Cuvinte-cheie: terapie anticancer, cardiotoxicitate, efecte secundare cardiovasculare Introduction Cardiac disease and cancer are by far the two most common disease conditions in the developed world.
Since that time, new data have become available, these have been incorporated into the Monograph, and taken into consideration in the present evaluation.
Cancer therapy is more effective than ever before at treating cancer, but has a price. Cardiotoxi city is a significant adverse effect of cancer treatment, and responsible for increased morbidity and mortality.
The routine uses in industrialized countries of hepatitis B and human papillomavirus vaccines successfully marked the prevention of liver and cervical cancer, is a very good example. All technological and scientific acquisitions in recombinant DNA technology over the last few years have resulted in new vaccines, thus making vaccination available to an increasing number of patients. Some recombinant vaccines have been already approved for medical use and others are in different stages of preclinical or clinical evaluation. Nowadays, novel approaches are being explored, such as: reverse vaccinology, bioconjugation technology, the use of generalized modules for membrane antigens and the use of RNA vaccines.
The most frequent and serious effect of chemotherapeutic agents on the cardiovascular system is heart failure 8 with ventricular systolic dysfunction.
Other toxic effects include hypertension, thromboembolic disease, pericardial disease, human papillomavirus and liver cancer and myocardial ischemia. In childhood cancer survivors cardiac mortality is increased eightfold.
Importantly, not all cardiovascular symptoms in patients treated for cancer are iatrogenic and the differential que es el papiloma humano explicacion para ninos should include co-morbid conditions or the adverse effects of other medications. The awareness of the cardiovascular risks of cancer treatment may influence the choice of treatment strategy and optimize delivery of therapy.
Additionally, this knowledge may human papillomavirus and liver cancer allow for timely interventions, such as life-style changes or treatment of subclinical disease, which may decrease potential harmful effects.

Chemotherapeutic agents and molecular targeted therapies can injure the cardiovascular system at central level by deteriorating the heart function or in the periphery by enhancing hemodynamic flow alterations and thrombotic events often latently present in oncology patients. Non-reversible or reversible: a cardinal distinction Historically, non-reversible cardiovascular side effects that eventually led to progressive cardiac disease were the consequence of some oncologic therapies; a prime example being anthracycline-induced cardiotoxicity leading to progressive systolic heart failure.
With the introduction of new cancer drugs, such as signalling inhibitors, a new phenomenon has been observed: cardiac human papillomavirus and liver cancer that resolves for most patients over time. In an effort to classify cardiotoxicity of cancer drugs, Ewer proposed a system to identify drugs that have the potential to cause irreversible damage Type I vs.
The benefits are certain in some cases: life years gained for those with curable disease, avoidance of morbidity, reassurance that the disease is at a very early stage, avoiding expenses of treatment for advanced cancers and extra years of productivity. But screening tests also have disadvantages, so a balanced decision must be made, with the help of clinical randomized trials. In this article I will present the current methods for screening accepted for general population and particular screening reserved for persons at high risk.
However, this classification system does have limitations; for example, trastuzumab, a Type II drug, can trigger irreversible cardiac damage in patients with severe preexisting cardiac disease, or potentiate anthracycline Type I cardiotoxicity. For cardiovascular side effects from other modern cancer therapeutics, such as angiogenesis inhibitors-induced arterial hypertension and nephrotoxicity, the reversibility remains unknown.
Cardiac dysfunction and heart failure Cardiac dysfunction and heart failure are among the most serious human papillomavirus and liver cancer side effects of systemic cancer treatment.
Conventional chemotherapeutics, such as anthracyclines, anti-metabolites, and cyclophosphamide, can induce permanent myocardial cell injury - albeit by diverse mechanisms - and by cardiac remodeling.
Understanding the mechanistic pathophysiology of cancer drug-associated cardiac dysfunction is important to predict, treat, and prevent these side effects, although it human papillomavirus and liver cancer be challenging to identify the proper mechanism in individual patients.
Data from endomyocardial biopsy and troponin I measurements suggest that myocyte injury may occur during or early after anthracycline exposure. However, due to substantial cardiac reserves and the activation human papillomavirus and liver cancer compensatory mechanisms, clinical manifestation may not become apparent until months to years after the initial chemotherapy exposure. Clinically, early cardiac side effects are typically reversible and self-limiting and include dysrhythmia, repolarization changes in the electrocardiogram, pericarditis, and less frequently myocarditis.
It remains uncertain whether patients who experience these early cardiac side effects are also more human papillomavirus and liver cancer to develop late anthracycline cardiotoxicity, a condition that leads to cardiomyopathy and systolic heart failure. Patients treated with anthracyclines are five times more likely to develop chronic heart failure or reduced left ventricular ejection fraction LVEF compared with those treated with a non-anthracycline-containing chemotherapy.
PRESENT AND FUTURE OF RECOMBINANT VACCINE TECHNOLOGIES
The incidence of anthracycline-induced cardiotoxicity is dose-dependent. Above this dosage, the rates of cardiotoxicity rise exponentially. However, there is significant interindividual heterogeneity; patients over 65 years of age and children may develop toxicity at lower cumulative dosages. Other factors that seem to influence sensitivity to anthracycline-induced cardiotoxicity include genetic predisposition, arterial hypertension, previous or concurrent mediastinal radiation therapy, and combination with alkylating or antimicrotubulechemotherapeutics; many other risk factors have been neuroendocrine cancer large cell, and from a practical standpoint we may assume that any insult that has previously damaged i.
It should be noted, however, that those risk factors that have human papillomavirus and liver cancer studied have had a relatively short follow-up period and long-term investigations are needed to better assess the true impact of risk factors for anthracycline cardiotoxicity.
Several methods were investigated to reduce anthracycline cardiotoxicity, including pharmacokinetic modification by liposomal encapsulation, alteration of chemical structure leading to drugs such as epirubicin, altering drug-infusion regimens to decrease peak plasma levels, and attenuation of iron chelation through pre-treatment with dexrazoxane.
