Over the past 10 years, enormous progress has been made in breast cancer (BC) treatment, leading to a substantial decline in BC mortality in Western countries. Although the following short review is necessarily incomplete, the discussion will highlight major achievements in the field. © 2017, Springer-Verlag Wien.


There remains uncertainty over optimal antithrombotic management strategy for patients with atrial fibrillation (AF) presenting with an acute coronary syndrome and/or undergoing percutaneous coronary intervention/stenting. Clinicians need to balance the risk of stroke and thromboembolism against the risk of recurrent cardiac ischaemia and/or stent thrombosis and the risk of bleeding. The full consensus document comprehensively reviews the published evidence and presents a consensus statement on a 'best practice' antithrombotic therapy guideline for the management of antithrombotic therapy in such AF patients. This executive summary highlights the main recommendations from the consensus document. © The Author 2010.

Objective The metabolic syndrome (MetS) is an increasing epidemiologic challenge and cardiovascular risk factor. Interleukin-6 (IL-6) is a cytokine that exerts its biological function via a complex orchestration of soluble and membrane bound receptors. We have investigated associations between IL-6 and its soluble receptors, soluble IL-6 receptor (sIL-6r) and soluble glycoprotein 130 (sGP130) and the metabolic syndrome. Furthermore, we have investigated possible associations with endothelial dysfunction and arterial stiffness. Methods A total of 563 subjects were included in this study. The Adult Treatment Panel III criteria of the National Cholesterol Education Program were used for the definition of MetS. We used commercially available ELISA to analyse circulating levels of the markers. Pulse wave propagation time (PWP) was determined to assess arterial stiffness. Results The criteria for having MetS were filled by 221 subjects. sGP130, sIL-6r and IL-6 levels were elevated in subjects with MetS (p < 0.05 for all markers), and are associated with increasing components of MetS. Particularly hypertriglyceridaemia, hypertension and fasting plasma glucose (FPG) seem to carry this association. sGP130 (p < 0.01), IL-6 (p < 0.05) and partially sIL-6r (p < 0.05) correlated with markers of endothelial function (E-selectin, I-CAM-1, V-CAM-1) and inversely with PWP after adjustment for relevant covariates. Conclusion sGP130, sIL-6r and IL-6 were significantly elevated in subjects with MetS. In addition, sGP130, IL-6 and partially sIL-6r were associated with markers of endothelial function and arterial stiffness. This finding sheds new light on the role of these inflammatory cytokines in subjects with MetS and the development and progression of clinically silent atherosclerosis. © 2013 Elsevier Inc.

Objectives This study sought to characterize major bleeding on the basis of the components of the major bleeding definition, to explore major bleeding by location, to define 30-day mortality after a major bleeding event, and to identify factors associated with major bleeding. Background Apixaban was shown to reduce the risk of major hemorrhage among patients with atrial fibrillation in the ARISTOTLE (Apixaban for Reduction in Stroke and Other Thromboembolic Events in Atrial Fibrillation) trial. Methods All patients who received at least 1 dose of a study drug were included. Major bleeding was defined according to the criteria of the International Society on Thrombosis and Haemostasis. Factors associated with major hemorrhage were identified using a multivariable Cox model. Results The on-treatment safety population included 18,140 patients. The rate of major hemorrhage among patients in the apixaban group was 2.13% per year compared with 3.09% per year in the warfarin group (hazard ratio [HR] 0.69, 95% confidence interval [CI]: 0.60 to 0.80; p < 0.001). Compared with warfarin, major extracranial hemorrhage associated with apixaban led to reduced hospitalization, medical or surgical intervention, transfusion, or change in antithrombotic therapy. Major hemorrhage followed by mortality within 30 days occurred half as often in apixaban-treated patients than in those receiving warfarin (HR 0.50, 95% CI: 0.33 to 0.74; p < 0.001). Older age, prior hemorrhage, prior stroke or transient ischemic attack, diabetes, lower creatinine clearance, decreased hematocrit, aspirin therapy, and nonsteroidal anti-inflammatory drugs were independently associated with an increased risk. Conclusions Apixaban, compared with warfarin, was associated with fewer intracranial hemorrhages, less adverse consequences following extracranial hemorrhage, and a 50% reduction in fatal consequences at 30 days in cases of major hemorrhage. © © 2014 by the American College of Cardiology Foundation Published by Elsevier Inc.

Effective chemoprevention of oestrogen receptor (ER)-positive breast cancer has been shown convincingly using several selective ER modulators and the aromatase inhibitor exemestane. Although these agents are well tolerated and the numbers needed-to-treat in the prevention setting are similar to other established preventive interventions, uptake has been poor in clinical practice because of difficulties in visualizing risk, predicting individual outcomes and measuring treatment benefit. In addition, new agents targeting ER-negative breast cancer are urgently needed. The development of new agents is hampered by the lack of suitable biomarkers and targets, as well as regulatory and financial considerations. Establishing breast cancer chemoprevention in standard clinical practice will require advances in many different fields, including biomarker research, the development of more powerful tools to predict and communicate the risks and benefits of treatments and establishing innovative trial designs. Furthermore, changes in regulatory procedures could reduce the size and cost of trials needed in the prevention setting. Identification of biomarkers for risk and efficacy that are easily accessible, such as blood-based biomarkers, will be key to future chemoprevention strategies. © 2013 Macmillan Publishers Limited.

For many years clopidogrel was the 'gold standard' ADP receptor antagonist in patients with coronary artery disease in combination with acetylsalicylic acid, i.e. in elective/stable patients after coronary stent implantation and in patients with acute coronary syndromes with/without percutaneous coronary intervention. For the latter group, in which the risk of atherothrombotic events is increased, the new ADP receptor-antagonists, e.g. prasugrel and ticagrelor, have shown their superiority over clopidogrel. This is mainly based on the fact that up to 30% of patients with acute coronary syndromes tend to be low- or non-responders to therapy due to non-genetic and/or genetic causes. Nevertheless, there is still room for the use of clopidogrel in the majority of patients with coronary artery disease. This review summarizes the latest knowledge of clopidogrel and its current indications. Copyright © 2012 S. Karger AG, Basel.

Stroke | Year: 2014

Background and Purpose - The efficacy and safety of different antiplatelet regimes for prevention of stroke in patients at high risk were investigated in a systematic review and meta-analysis. Methods - We searched the Cochrane Central Register of Controlled Trials, MEDLINE, and Web of Science. Twenty-two studies comprising 173 371 patients were included. Results - In the overall population, dual antiplatelet therapy (DAPT) with aspirin and clopidogrel in comparison to aspirin monotherapy reduced the relative risk of total stroke by 20% (risk ratio [RR], 0.80; 95% confidence interval [CI], 0.73-0.88; P<0.0001; I 2=28%) and of ischemic stroke or transient ischemic attack by 23% (RR, 0.77; 95% CI, 0.69-0.85; P<0.0001; I2=18%) without increasing the risk of intracranial hemorrhage. In the secondary prevention cohort, DAPT with aspirin and clopidogrel also reduced the relative risk of total stroke by 24% as compared with aspirin alone (RR, 0.76; 95% CI, 0.68-0.86; P<0.0001; I2=0%). DAPT with prasugrel or ticagrelor and aspirin versus DAPT with clopidogrel and aspirin was not associated with a risk reduction of stroke. Conclusions - DAPT with clopidogrel and aspirin compared with aspirin effectively reduces the risk of total and ischemic stroke in the overall cohort consisting of patients with cardiovascular disease without increase in intracranial hemorrhage, as well as decreases the risk of a recurrent total stroke in patients with a previous stroke/transient ischemic attack. Our meta-analysis suggests that DAPT including low-dose aspirin (75-100 mg) and clopidogrel (75 mg) should be further investigated as a strategy to reduce recurrent strokes. © 2013 American Heart Association, Inc.

The health burden of cancer is increasing in China, with more than 1·6 million people being diagnosed and 1·2 million people dying of the disease each year. As in most other countries, breast cancer is now the most common cancer in Chinese women; cases in China account for 12·2% of all newly diagnosed breast cancers and 9·6% of all deaths from breast cancer worldwide. China's proportional contribution to global rates is increasing rapidly because of the population's rising socioeconomic status and unique reproductive patterns. In this Review we present an overview of present control measures for breast cancer across China, and emphasise epidemiological and socioeconomic diversities and disparities in access to care for various subpopulations. We describe demographic differences between China and high-income countries, and also within geographical and socioeconomic regions of China. These disparities between China and high-income countries include younger age at onset of breast cancer; the unique one-child policy; lower rates of provision and uptake for screening for breast cancer; delays in diagnosis that result in more advanced stage of disease at presentation; inadequate resources; and a lack of awareness about breast cancer in the Chinese population. Finally, we recommend key measures that could contribute to improved health outcomes for patients with breast cancer in China. © 2014 Elsevier Ltd.

Antiplatelet therapy in acute coronary syndromes is essential for preventing stent thrombosis and for reducing major adverse cardiovascular events. Treatment strategy has changed over the last years by frequent use of more active agents inhibiting the ADP mediated activation of platelets instead of clopidogrel, such as prasugrel and ticagrelor. Compared to clopidogrel these modern antiplatelet drugs showed a significant reduction of efficacy endpoints as well as an acceptable safety profile in large multicenter randomized trials (TRITON TIMI 38, PLATO). Going in with higher efficacy a generally higher bleeding risk of prasugrel could be reduced by optimizing the maintenance dose in elderly and underweight patients (TRILOGY-ACS). However even prasugrel and ticagrelor have shown a delayed onset of action in special patient populations (e.g. STEMI) suggesting that the optimal ADP inhibitor has not been found yet. Results of the CHAMPION PHOENIX trial indicate that cangrelor, an intravenous agent, might fulfill these high expectations of an ideal platelet inhibitor in the first hours of an ACS in special patient cohorts. This review summarizes the results of most important clinical studies investigating the novel P2Y12 receptor inhibiting antiplatelet drugs. © Schattauer 2014.
