Gender-specific risks for incident cancer in patients with different heart failure phenotypes

BACKGROUND

There is conflicting evidence regarding whether heart failure (HF) increases the risk of developing cancer.

OBJECTIVE

This study aimed to assess the association between HF and incident cancer, considering gender differences and HF phenotypes.

METHODS

This retrospective study was conducted on data of adult individuals, free of cancer at baseline, from the First Affiliated Hospital of Wenzhou Medical University between January 2009 and February 2023. The patients with HF were categorized as HF with preserved ejection fraction (HFpEF) and HF with reduced ejection fraction (HFrEF). The primary outcome was incident cancer, including obesity-related, tobacco-related, lung, colorectal and breast cancers.

RESULTS

Of 33 033 individuals enrolled, 16 722 were diagnosed with HF, including 10 086 (60.3%) with HFpEF and 6636 (39.7%) with HFrEF. During a median follow-up period of 4.6 years (inter-quartile range: 2.6-7.3), incident cancer was diagnosed in 10.5% (1707 patients) of the non-HF group and 15.1% (2533 individuals) of the HF group. After adjusting for potential confounding factors, patients with HF had a 58% increased risk of cancer than those without HF [adjusted hazard ratio (HR) 1.58, 95% confidence interval (CI) 1.48-1.69, P < 0.001]. This risk was consistent across genders (female: adjusted HR 1.95, 95% CI 1.74-2.18, P < 0.001; male: adjusted HR 1.41, 95% CI 1.30-1.54, P < 0.001) and HF phenotypes (HFpEF: adjusted HR 1.69, 95% CI 1.57-1.81, P < 0.001; HFrEF: adjusted HR 1.32, 95% CI 1.20-1.46, P < 0.001).

CONCLUSIONS

Both HFpEF and HFrEF are associated with an increased risk of incident cancer. This correlation maintains its validity across genders.

The Impact of Geriatric Conditions in Elderly Patients with Coronary Heart Disease: A State-of-the-Art Review

The growing geriatric population presenting with coronary artery disease poses a primary challenge for healthcare services. This is a highly heterogeneous population, often underrepresented in studies and clinical trials, with distinctive characteristics that render them particularly vulnerable to standard management/approaches. In this review, we aim to summarize the available evidence on the treatment of acute coronary syndrome in the elderly. Additionally, we contextualize frailty, comorbidity, sarcopenia, and cognitive impairment, common in these patients, within the realm of coronary artery disease, proposing strategies for each case that may assist in therapeutic approaches.

Protective Effect of Vitexin Against IL-17-Induced Vascular Endothelial Inflammation Through Keap1/Nrf2-Dependent Signaling Pathway

SCOPE

Vitexin, a C-glycosylated flavonoid, is abundant in food sources and has potential health-beneficial properties. However, the targets for its beneficial effects remain largely unknown. This study aims to establish an in vitro cell model of vascular low-grade inflammation and explore the antiinflammatory mechanism of vitexin.

METHODS AND RESULTS

Low-dose TNFα and IL-17 are combined to establish a cell model of vascular low-grade inflammation. Cell-based studies show that low-dose TNFα (1 ng mL-1) alone has a slight effect, but its combination with IL-17 can potently induce protein expression of inflammatory cytokines, leading to an inflammatory state. However, the vascular inflammation caused by low-dose TNF plus IL-17 does not lead to oxidative stress, and reactive oxygen species (ROS) does not involved in developing this inflammation. Vitexin can be absorbed by human umbilical vein endothelial (HUVEC) cells to increase the Nrf2 protein level and attenuate inflammation. In addition, the antiinflammatory effect of vitexin is blocked by the knockdown of Nrf2. Further localized surface plasmon resonance, drug affinity responsive target stability, and molecular docking demonstrate that vitexin can directly interact with Keap1 to disrupt Keap1-Nrf2 interaction and thus activate Nrf2. Treatment of mice with a bolus oral gavage of vitexin (100 mg kg-1 body weight) or a high-fat diet supplemented with vitexin (5 mg kg-1 body weight per day) for 12 weeks confirms the rapid increase in blood vitexin levels and subsequent incorporation into blood vessels to activate Nrf2 and ameliorate inflammation in vivo.

CONCLUSION

The findings provide a reliable cell model of vascular low-grade inflammation and indicate Nrf2 protein as the potential target of vitexin to inhibit vascular inflammation.

The Development of a Chest-Pain Protocol for Women Presenting to the Emergency Department

Cardiovascular disease (CVD) is the leading cause of death in women worldwide, and of premature death in women in Canada. Despite improvements in cardiovascular care over the past 15-20 years, acute coronary syndrome (ACS) and CVD mortality continue to increase among women in Canada. Chest pain is a common symptom leading to emergency department visits for both men and women. However, women with ACS experience worse outcomes. compared with those of men, due to misdiagnosis or lack of diagnosis resulting in delayed care and underuse of guideline-directed medical therapies. CVD mortality rates are highest in Indigenous and racialized women and those with a disproportionately high number of adverse social determinants of health. CVD remains underrecognized, underdiagnosed, undertreated, and underresearched in women. Moreover, a lack of awareness of unique symptoms, clinical presentations, and sex-and-gender specific CVD risk factors, by healthcare professionals, leads to outcome disparities. In response to this knowledge gap, in acute recognition and management of chest-pain syndromes in women, the Canadian Women's Heart Health Alliance performed a needs assessment and review of CVD risk factors and ACS pathophysiology, through a sex and gender lens, and then developed a unique chest-pain assessment protocol utilizing modified dynamic programming algorithmic methodology. The resulting algorithmic protocol is presented. The output is intended as a quick reference algorithm that could be posted in emergency departments and other acute-care settings. Next steps include protocol implementation evaluation and impact assessment on CVD outcomes in women.

CVD phenotyping in oncologic disorders: cardio-miRNAs as a potential target to improve individual outcomes in revers cardio-oncology

With the increase of aging population and prevalence of obesity, the incidence of cardiovascular disease (CVD) and cancer has also presented an increasing tendency. These two different diseases, which share some common risk factors. Relevant studies in the field of reversing Cardio-Oncology have shown that the phenotype of CVD has a significant adverse effect on tumor prognosis, which is mainly manifested by a positive correlation between CVD and malignant progression of concomitant tumors. This distal crosstalk and the link between different diseases makes us aware of the importance of diagnosis, prediction, management and personalized treatment of systemic diseases. The circulatory system bridges the interaction between CVD and cancer, which suggests that we need to fully consider the systemic and holistic characteristics of these two diseases in the process of clinical treatment. The circulating exosome-miRNAs has been intrinsically associated with CVD -related regulation, which has become one of the focuses on clinical and basic research (as biomarker). The changes in the expression profiles of cardiovascular disease-associated miRNAs (Cardio-miRNAs) may adversely affect concomitant tumors. In this article, we sorted and screened CVD and tumor-related miRNA data based on literature, then summarized their commonalities and characteristics (several important pathways), and further discussed the conclusions of Cardio-Oncology related experimental studies. We take a holistic approach to considering CVD as a risk factor for tumor malignancy, which provides an in-depth analysis of the various regulatory mechanisms or pathways involved in the dual attribute miRNAs (Cardio-/Onco-miRNAs). These mechanisms will be key to revealing the systemic effects of CVD on tumors and highlight the holistic nature of different diseases. Therefore, the Cardio-miRNAs should be given great attention from researchers in the field of CVD and tumors, which might become new targets for tumor treatment. Meanwhile, based on the principles of precision medicine (such as the predictive preventive personalized medicine, 3PM) and reverse Cardio-oncology to better improve individual outcomes, we should consider developing personalized medicine and systemic therapy for cancer from the perspective of protecting cardiovascular function.

Mechanisms, prevalence and management of cardiac arrhythmias in cancer patients: a comprehensive review

Recently, prognosis and survival of cancer patients has improved due to progression and refinement of cancer therapies; however, cardiovascular sequelae in this population augmented and now represent the second cause of death in oncological patients. Initially, the main issue was represented by heart failure and coronary artery disease, but a growing body of evidence has now shed light on the increased arrhythmic risk of this population, atrial fibrillation being the most frequently encountered. Awareness of arrhythmic complications of cancer and its treatments may help oncologists and cardiologists to develop targeted approaches for the management of arrhythmias in this population. In this review, we provide an updated overview of the mechanisms triggering cardiac arrhythmias in cancer patients, their prevalence and management.

Atrial Fibrillation Incidence Associated With Exposure to Anticancer Drugs Used as Monotherapy in Clinical Trials

Background

The incidence of atrial fibrillation (AF) associated with anticancer drugs in cancer patients remains incompletely defined.

Objectives

The primary outcome was the annualized incidence rate of AF reporting associated with exposure to 1 of 19 anticancer drugs used as monotherapy in clinical trials. The authors also report the annualized incidence rate of AF reported in the placebo arms of these trials.

Methods

The authors systematically searched ClinicalTrials.gov for phase 2 and 3 cancer trials studying 19 different anticancer drugs of interest used as monotherapy, up to September 18, 2020. The authors performed a random-effects meta-analysis to compute summary AF annualized incidence rate with its 95% CI using log transformation and inverse variance weighting.

Results

A total of 191 clinical trials (47.1% were randomized) of 16 anticancer drugs across 26,604 patients were included. Incidence rates could be calculated for 15 drugs administered singly as monotherapy. Summary annualized incidence rates of AF reporting associated with exposure to 1 of the 15 anticancer drugs used as monotherapy were derived; these ranged from 0.26 to 4.92 per 100 person-years. The 3 highest annualized incidence rates of AF reporting were found for ibrutinib 4.92 (95% CI: 2.91-8.31), clofarabine 2.38 (95% CI: 0.66-8.55), and ponatinib 2.35 (95% CI: 1.78-3.12) per 100 person-years. Summary annualized incidence rate of AF reporting in the placebo arms was 0.25 per 100 person-years (95% CI: 0.10-0.65).

Conclusions

AF reporting is not a rare event associated with anticancer drugs in clinical trials. A systematic and standardized AF detection should be considered in oncological trials, particularly those studying anticancer drugs associated with high AF rates.

tRNA-like Transcripts from the NEAT1-MALAT1 Genomic Region Critically Influence Human Innate Immunity and Macrophage Functions

The evolutionary conserved NEAT1-MALAT1 gene cluster generates large noncoding transcripts remaining nuclear, while tRNA-like transcripts (mascRNA, menRNA) enzymatically generated from these precursors translocate to the cytosol. Whereas functions have been assigned to the nuclear transcripts, data on biological functions of the small cytosolic transcripts are sparse. We previously found NEAT1^-/- and MALAT1^-/- mice to display massive atherosclerosis and vascular inflammation. Here, employing selective targeted disruption of menRNA or mascRNA, we investigate the tRNA-like molecules as critical components of innate immunity. CRISPR-generated human ΔmascRNA and ΔmenRNA monocytes/macrophages display defective innate immune sensing, loss of cytokine control, imbalance of growth/angiogenic factor expression impacting upon angiogenesis, and altered cell-cell interaction systems. Antiviral response, foam cell formation/oxLDL uptake, and M1/M2 polarization are defective in ΔmascRNA/ΔmenRNA macrophages, defining first biological functions of menRNA and describing new functions of mascRNA. menRNA and mascRNA represent novel components of innate immunity arising from the noncoding genome. They appear as prototypes of a new class of noncoding RNAs distinct from others (miRNAs, siRNAs) by biosynthetic pathway and intracellular kinetics. Their NEAT1-MALAT1 region of origin appears as archetype of a functionally highly integrated RNA processing system.

The Alterations and Roles of Glycosaminoglycans in Human Diseases

Glycosaminoglycans (GAGs) are a heterogeneous family of linear polysaccharides which are composed of a repeating disaccharide unit. They are also linked to core proteins to form proteoglycans (PGs). GAGs/PGs are major components of the cell surface and the extracellular matrix (ECM), and they display critical roles in development, normal function, and damage response in the body. Some properties (such as expression quantity, molecular weight, and sulfation pattern) of GAGs may be altered under pathological conditions. Due to the close connection between these properties and the function of GAGs/PGs, the alterations are often associated with enormous changes in the physiological/pathological status of cells and organs. Therefore, these GAGs/PGs may serve as marker molecules of disease. This review aimed to investigate the structural alterations and roles of GAGs/PGs in a range of diseases, such as atherosclerosis, cancer, diabetes, neurodegenerative disease, and virus infection. It is hoped to provide a reference for disease diagnosis, monitoring, prognosis, and drug development.

Extracellular Vesicles, Inflammation, and Cardiovascular Disease

Cardiovascular disease is a leading cause of death worldwide. The underlying mechanisms of most cardiovascular disorders involve innate and adaptive immune responses, and extracellular vesicles are implicated in both. In this review, we describe the mechanistic role of extracellular vesicles at the intersection of inflammatory processes and cardiovascular disease. Our discussion focuses on atherosclerosis, myocardial ischemia and ischemic heart disease, heart failure, aortic aneurysms, and valvular pathology.

Potential pathophysiologic mechanisms underlying the inherent risk of cancer in patients with atherosclerotic cardiovascular disease

Emerging evidence demonstrates an intimate interplay between cardiovascular disease and cancer pathophysiology. The aim of this review is to shed light on the common biological pathways underlying cardiovascular disease and cancer. These common pathways form the basis of "reverse cardio-oncology". We focus on the role of inflammation, stress response, cell proliferation, angiogenesis and tissue remodeling, neurohormonal system activation, and genomic instability as pathogenic pathways shared by cardiovascular disease and cancer. We also discuss shared mediators that may have a potential role as biomarkers for risk prediction in both diseases. Furthermore, we highlight current knowledge on biological pathways and mediators that are upregulated in diabetes and myocardial infarction and may be involved in tumorigenesis. On the basis of the shared pathophysiologic mechanisms, we also suggest an integrated approach to reduce the global burden of both cardiovascular disease and cancer.

Management of Acute Coronary Syndrome in Cancer Patients: It's High Time We Dealt with It

Cancer patients have an increased risk of cardiovascular disease and, notably, a significant prevalence of acute coronary syndrome (ACS). It has been shown that an elevated presence of cardiovascular risk factors in this setting leads to an interaction between these two conditions, influencing their therapeutic strategies and contributing to higher mortality. Nonetheless, cancer patients have generally not been evaluated in ACS trials, so that the treatment in these cases is still not fully known. We reviewed the current literature and discussed the best management for these very high-risk patients. The treatment strategy must be tailored based on the cancer type and stage, balancing thrombotic and bleeding risks. When the prognosis is longer than six months, especially if a clinical instability coexists, patients with ACS and cancer should be referred for percutaneous coronary intervention (PCI) as soon as possible. Moreover, an invasive strategy should be preferred in STEMI patients as well as in NSTEMI patients who are considered as high risk. On the contrary, in clinically stable NSTEMI patients, a conservative non-invasive strategy could be adopted, especially in cases of a poor life expectancy and/or of high risk of bleeding. Drug-Eluting-Stents (DES) should be the first choice if an invasive strategy is adopted. Conservative therapy could instead be considered in cancer patients with more stable CAD at an increased risk of major bleeding complications. However, the duration of dual antiplatelet therapy (DAPT) with aspirin and clopidogrel is recommended, but it should be as short as possible, whereas triple antithrombotic therapy is non-advised because it significantly increases the risk of bleeding. ACS management among cancer patients should be based on an accurate evaluation of the risk of thrombosis and bleeding. Future studies focused on choosing optimal strategies in tumor patients with ACS should be performed to treat this subset of patients better.

Cell Membrane Vesicles with Enriched CXCR4 Display Enhances Their Targeted Delivery as Drug Carriers to Inflammatory Sites

Cell membrane vesicles (CMVs) are composed of natural cell membranes which makes them effective drug delivery systems with low immunogenicity and prolonged circulation time. However, targeting delivery of CMVs in vivo for clinical applications is still a major challenge. In this study, CXCR4 recombinant lentivirus is transfected into MC-3T3 cells and membrane CXCR4-enriched MC-3T3 cells are obtained. CMVs with enriched membrane CXCR4 display (CXCR4-CMVs) are obtained from the transfected MC-3T3 cells. Curcumin, an effective natural anti-inflammatory compound, is encapsulated into CXCR4-CMVs through physical entrapment (CXCR4/Cur-CMVs), with the membrane integrity of CXCR4/Cur-CMVs being well-preserved. CXCR4/Cur-CMVs induce enhanced M2 macrophage polarization, exhibit anti-inflammatory effects, and significantly improve homing via the CXCR4/CXCL12 axis in vitro. Utilizing ulcerative colitis and apical periodontitis as inflammatory disease models, it is found that CXCR4/Cur-CMVs are obviously aggregated within inflammatory areas after intravenous administration, which results in significant amelioration of ulcerative colitis and apical periodontitis. Therefore, this research may provide a feasible and innovative approach for fabricating an inflammatory site-targeting delivery system, by engineering CMVs to increase membrane-presenting CXCR4 receptor.

Depression symptoms mediate the association between workplace stress and interleukin 6 in women, but not men: The Whitehall II study

Workplace stress and depression are positively related with inflammation, and each other. Low-grade inflammation and concurrent high levels of workplace stress or depression has been related with future morbidity. The potential pathway between constructs however, remains elusive. For the first time, this study explored the concurrent relationship between workplace stress, depressive symptomology and low-grade inflammation, and considered the role of gender in these relationships. Data from the Whitehall II cohort study (N ​= ​2528, M_age ​= ​57.01, 23.7% females) provided measures of workplace stress (job demand-control; JDC), depressive symptomology (Centre for Epidemiological Studies Depression scale; CES-D) and circulating inflammatory markers, interleukin-6 (IL-6) and C-reactive protein (CRP) collected on the same day from a single time point. Females had higher workplace stress, depressive symptoms and lower serum IL-6 concentrations. For males, higher workplace stress was associated with higher depressive symptoms. For females, higher depressive symptoms were related with elevated IL-6 levels, and both higher workplace stress and IL-6 levels were associated with higher depressive symptoms. Higher depressive symptoms were related with higher CRP levels in men only. Higher depressive symptoms statistically mediated the relationship between higher workplace stress and IL-6 levels in females only, b ​= ​0.016, CI [0.002, 0.039]. Females in this large cohort had higher levels of job strain, depression and lower IL-6 concentrations than males. In females, higher depressive symptoms were associated with higher serum IL-6 levels and workplace stress was not. Considered together, these findings suggest that low job control may be more apparent in females than males, but it is primarily negative affect that drives the positive relationship between work stress and serum IL-6 concentrations in females. Replicating the current design with a suitably proximal follow-up is required to determine if the associations identified are causal.

•

Females had higher workplace stress, depressive symptoms and lower IL-6.

•

Association between stress, depression and inflammation was stronger in women.

•

Among females, depressive symptoms and not stress associated with serum IL-6. .

[Role of the cardiologist in the management of oncology patients. Where are we standing, and what to expect in the future?]

Cardiovascular and oncological diseases are the main causes of death worldwide. Cancer patients have an increased risk of cardiovascular diseases but, at the same time, cardiovascular patients experience a higher risk of cancer. This relationship goes beyond the toxicity concerning cancer treatment. Cardio-oncology goal is to facilitate cancer therapy by implementing preventive strategies that allow early diagnosis and treatment of potential cancer therapy-induced cardiovascular complications, being heart failure the most fearest one. The creation of Cardio-oncology services has the potential to impact daily clinical practice and public health, with clear implications into the future.

Cardio-oncology: where do we stand for in Belgium?

Cardiovascular disease (CVD) and cancer represent the two main causes of death in industrialised countries. Both share common risk factors (diabetes, obesity, hypertension, diet, smoking, etc.). The associated timing of CVD and cancer onset is thus largely influenced by modifiable risk factors. Advances in cancer treatment have extended the lives of patients with cancer, but for some at the cost of adverse cardiovascular events. The rapidly growing number of patients surviving cancer, often in the setting of advanced age, new or pre-existing CV disease and risk factors, the management of these patients has become the concern of experts in cardio-oncology. The goal of cardio-oncology is to provide optimal care for patients with cancer and/or at risk of cardiovascular disease. To date, no specific cardio-oncology teaching programme is available in Belgium. The present paper reports the results of the Belgian Society of Cardiology (BSC) survey on cardio-oncology. The vast majority of respondents (154/159, 97%) are in favour of organising courses or educational meetings on cardio-oncology. A dedicated cardio-oncology clinic was present in only 40% of the hospitals that participated in the survey. Compared to the data collected by the European Society of Cardiology, the number of respondents considering themselves as experts in the management of left ventricular dysfunction or atrial fibrillation complicating cancer treatment was much lower in Belgium (11% vs. 30%).

Elevated preoperative neutrophil-to-lymphocyte ratio predicts early adverse outcomes in uncomplicated type B aortic dissection undergoing TEVAR

BACKGROUND

Thoracic aortic endovascular repair (TEVAR) of uncomplicated type B aortic dissection (uTBAD) has favorable long-term outcomes but higher early adverse events compared with the optimal medical treatment. Recently, clinical evidence concerning vascular surgery indicates that elevated preoperative systemic inflammatory response predicts adverse clinical events. The aim of our study was to evaluate the relationship between preoperative neutrophil-to-lymphocyte ratio (NLR) and early outcomes of uTBAD patients undergoing TEVAR.

RESULTS

216 patients diagnosed with uTBAD were included in this retrospective study between January 2015 and December 2018. The median (IQR) follow-up period was 21 (15-33) months. An early adverse event was defined as occurring within 2 years after the procedure. Median patient age was 60 (IQR, 48-68) years and 78.7 % were male. Early adverse events occurred in 24 patients (11.1 %). In the multivariable analysis, preoperative NLR (HR per SD, 1.98; 95 % CI, 1.14-3.44; P = 0.015) was associated with 2-year adverse events.

CONCLUSIONS

NLR is an independent predictive factor of early adverse events in uTBAD patients undergoing TEVAR.

Neutrophil Phenotypes in Coronary Artery Disease

Clinical evidence indicates that innate immune cells may contribute to acute coronary syndrome (ACS). Our prospective study aimed at investigating the association of neutrophil phenotypes with ACS. 108 patients were categorized into chronic stable coronary artery disease (n = 37), unstable angina (UA) (n = 19), Non-ST-Elevation Myocardial Infarction (NSTEMI) (n = 25), and ST-Elevation Myocardial Infarction (STEMI) (n = 27). At the time of inclusion, blood neutrophil subpopulations were analysed by flow cytometry. Differential blood cell count and plasma levels of neutrophilic soluble markers were recorded at admission and, for half of patients, at six-month follow-up. STEMI and NSTEMI patients displayed higher neutrophil count and neutrophil-to-lymphocyte ratio than stable and UA patients (p < 0.0001), which normalized at six-month post-MI. Atypical low-density neutrophils were detected in the blood of the four patient groups. STEMI patients were characterized by elevated percentages of band cells compared to the other patients (p = 0.019). Multivariable logistic regression analysis revealed that plasma levels of total myeloperoxidase was associated with STEMI compared to stable (OR: 1.434; 95% CI: 1.119–1.837; P < 0.0001), UA (1.47; 1.146–1.886; p = 0.002), and NSTEMI (1.213; 1.1–1.134; p = 0.0001) patients, while increased neutrophil side scatter (SSC) signal intensity was associated with NSTEMI compared to stable patients (3.828; 1.033–14.184; p = 0.045). Hence, changes in neutrophil phenotype are concomitant to ACS.

Identification of anticancer drugs associated with atrial fibrillation: analysis of the WHO pharmacovigilance database

AIMS

The explosion of novel anticancer therapies has meant emergence of cardiotoxicity signals including atrial fibrillation (AF). Reliable data concerning the liability of anticancer drugs in inducing AF are scarce. Using the World Health Organization individual case safety report database, VigiBase®, we aimed to determine the association between anticancer drugs and AF.

METHODS AND RESULTS

A disproportionality analysis evaluating the multivariable-adjusted reporting odds ratios for AF with their 99.97% confidence intervals was performed for 176 U.S. Food and Drug Administration (FDA)- or European Medicines Agency (EMA)-labelled anticancer drugs in VigiBase®, followed by a descriptive analysis of AF cases for the anticancer drugs identified in VigiBase®. ClinicalTrial registration number: NCT03530215. A total of 11 757 AF cases associated with at least one anticancer drug were identified in VigiBase® of which 95.8% were deemed serious. Nineteen anticancer drugs were significantly associated with AF of which 14 (74%) are used in haematologic malignancies and 9 (45%) represented new AF associations not previously confirmed in literature including immunomodulating agents (lenalidomide, pomalidomide), several kinase inhibitors (nilotinib, ponatinib, midostaurin), antimetabolites (azacytidine, clofarabine), docetaxel (taxane), and obinutuzumab, an anti-CD20 monoclonal antibody.

CONCLUSION

Although cancer malignancy itself may generate AF, we identified 19 anticancer drugs significantly associated with a significant increase in AF over-reporting. This pharmacovigilance study provides evidence that anticancer drugs themselves could represent independent risk factors for AF development. Dedicated prospective clinical trials are now required to confirm these 19 associations. This list of suspected anticancer drugs should be known by physicians when confronted to AF in cancer patients, particularly in case of haematologic malignancies.
