Background and Aims: Coexisting atrial fibrillation (AF) and cancer challenge the management of both. The aim of the study is to comprehensively provide the epidemiology of coexisting AF and cancer., Methods: Using Dutch nationwide statistics, individuals with incident AF (n = 320 139) or cancer (n = 472 745) were identified during the period 2015-19. Dutch inhabitants without a history of AF (n = 320 135) or cancer (n = 472 741) were matched as control cohorts by demographic characteristics. Prevalence of cancer/AF at baseline, 1-year risk of cancer/AF diagnosis, and their time trends were determined. The association of cancer/AF diagnosis with all-cause mortality among those with AF/cancer was estimated by using time-dependent Cox regression., Results: The rate of prevalence of cancer in the AF cohort was 12.6% (increasing from 11.9% to 13.2%) compared with 5.6% in the controls; 1-year cancer risk was 2.5% (stable over years) compared with 1.8% in the controls [adjusted hazard ratio (aHR) 1.52, 95% confidence interval (CI) 1.46-1.58], which was similar by cancer type. The rate of prevalence of AF in the cancer cohort was 7.5% (increasing from 6.9% to 8.2%) compared with 4.3% in the controls; 1-year AF risk was 2.8% (stable over years) compared with 1.2% in the controls (aHR 2.78, 95% CI 2.69-2.87), but cancers of the oesophagus, lung, stomach, myeloma, and lymphoma were associated with higher hazards of AF than other cancer types. Both cancer diagnosed after incident AF (aHR 7.77, 95% CI 7.45-8.11) and AF diagnosed after incident cancer (aHR 2.55, 95% CI 2.47-2.63) were associated with all-cause mortality, but the strength of the association varied by cancer type., Conclusions: Atrial fibrillation and cancer were associated bidirectionally and were increasingly coexisting, but AF risk varied by cancer type. Coexisting AF and cancer were negatively associated with survival., (© The Author(s) 2024. Published by Oxford University Press on behalf of the European Society of Cardiology.)

Background: Adolescent and young adult cancer survivors (AYAs, aged 18-39 years at first diagnosis) have a higher second cancer risk. Accelerated aging is hypothesized as underlying mechanism and has been described clinically by 6 indicators; fatigue, low quality of sleep, low mood, lack of motivation, subjective memory complaints, and poor exercise tolerance. Using patient-reported outcomes, we aimed to identify clusters of accelerated aging among AYA cancer survivors and to investigate their association with second cancer development., Patients and Methods: Patient, tumor, and treatment data were obtained from the Netherlands Cancer Registry. Patient-reported clinical indicators and second cancer data were obtained from the SURVivors (5-20 years) of cancer in AYAs (SURVAYA) questionnaire study between 1999 and 2015. Latent class and multivariable logistic regression analyses were performed., Results: In total, n = 3734 AYA survivors with known second cancer status (n = 278 [7.4%] second cancers) were included. Four latent clusters were identified and named based on their clinical indicator features; (1) high accelerated aging (31.3%), (2) intermediate accelerated aging without poor exercise tolerance (15.1%), (3) intermediate accelerated aging without lack of motivation (27.4%), and (4) low accelerated aging (26.2%). AYAs in the high accelerated aging cluster were more likely to have second cancer (odds ratio: 1.6; 95% CI, 1.1-2.3) compared to the low accelerated aging cluster., Conclusion: AYAs with a higher burden of accelerated aging were more likely to develop a second cancer. Validation of the clinical indicators and how to best capture them is needed to improve (early) detection of AYAs at high risk of developing second cancer., (© The Author(s) 2023.

Purpose: Adolescent and young adult cancer survivors (AYAs) are at increased risk of long-term and late effects, and experience unmet needs, impacting their health-related quality of life (HRQoL). In order to provide and optimize supportive care and targeted interventions for this unique population, it is important to study HRQoL factors' interconnectedness on a population level. Therefore, this network analysis was performed with the aim to explore the interconnectedness between HRQoL factors, in the analysis described as nodes, among long-term AYAs., Methods: This population-based cohort study used cross-sectional survey data of long-term AYAs, who were identified by the Netherlands Cancer Registry (NCR). Participants completed a one-time survey (SURVAYA study), including the EORTC survivorship questionnaire (QLQ-SURV111) to assess their long-term HRQoL outcomes and sociodemographic characteristics. The NCR provided the clinical data. Descriptive statistics and a network analysis, including network clustering, were performed., Results: In total, 3596 AYAs (on average 12.4 years post diagnosis) were included in our network analysis. The network was proven stable and reliable and, in total, four clusters were identified, including a worriment, daily functioning, psychological, and sexual cluster. Negative health outlook, part of the worriment cluster, was the node with the highest strength and its partial correlation with health distress was significantly different from all other partial correlations., Conclusion: This study shows the results of a stable and reliable network analysis based on HRQoL data of long-term AYAs, and identified nodes, correlations, and clusters that could be intervened on to improve the HRQoL outcomes of AYAs., (© 2024.

Background and Aims: Cancer provides challenges to the continuity of anticoagulant treatment in patients with atrial fibrillation (AF), e.g. through cancer-related surgery or complications. We aimed to provide data on the incidence and reasons for interrupting and discontinuing anticoagulant treatment in AF patients with cancer and to assess its contribution to the risk of thromboembolism (TE) and major bleeding (MB)., Methods: This retrospective study identified AF patients with cancer in two hospitals between 2012 and 2017. Data on anticoagulant treatment, TE and MB were collected during two-year follow-up. Incidence rates (IR) per 100 patient-years and adjusted hazard ratios (aHR) were obtained for TE and MB occurring during on- and off-anticoagulant treatment, during interruption and after resumption, and after permanent discontinuation., Results: 1213 AF patients with cancer were identified, of which 140 patients permanently discontinued anticoagulants and 426 patients experienced one or more interruptions. Anticoagulation was most often interrupted or discontinued due to cancer-related treatment (n = 441, 62 %), bleeding (n = 129, 18 %) or end of life (n = 36, 5 %). The risk of TE was highest off-anticoagulation and during interruptions, with IRs of 19 (14-25)) and 105 (64-13), and aHRs of 3.1 (1.9-5.0) and 4.6 (2.4-9.0), respectively. Major bleeding risk were not only increased during an interruption, but also in the first 30 days after resumption, with IRs of 33 (12-72) and 30 (17-48), and aHRs of 3.3 (1.1-9.8) and 2.4 (1.2-4.6), respectively., Conclusions: Interruption of anticoagulation therapy harbors high TE and MB risk in AF patients with cancer. The high incidence rates call for better (periprocedural) anticoagulant management strategies tailored to the cancer setting., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 The Authors.

Background: Despite growing (inter)national awareness and appreciation, age-specific care is still not always self-evident and accepted as standard of care for adolescent and young adult (AYA) cancer patients. It is unknown whether long-term AYA cancer survivors have missed age-specific care, and if so, which survivors missed it and regarding which topics., Methods: The Netherlands Cancer Registry (NCR) identified all long-term AYA cancer survivors (aged 18-39 years at initial cancer diagnosis, 5-20 years past diagnosis) in the Netherlands, who were invited to participate in a population-based, observational, cross-sectional questionnaire study (SURVAYA study), including questions on care needs., Results: In total, 3.989 AYAs participated (35.3% response rate). One-third of them had a need for age-specific care (33.5%), 41.2% had no need and 25.3% did not know whether they had a need. Those who had a need for age-specific care were significantly more often female, higher educated, diagnosed at a younger age, and treated with chemotherapy, radiotherapy or hormone therapy. Most frequent topics were disease and treatment (29.7%), emotions (24.1%), friends (22.6%), family and children (15.6%), fertility and pregnancy (14.8%), work and reintegration (10.5%), care not tailored (13.8%), and overarching care and life (27.7%). Palliative care (0.0%), spirituality (0.2%), death (0.7%), complementary care (0.7%), and late effects (1.3%) were mentioned least., Conclusions: A substantial proportion of long-term AYA cancer survivors showed a need for age-specific care, varying by sociodemographic and clinical factors, on a wide variety of topics, which could be targeted to improve current AYA care services., (© 2023 The Authors.

Since several trials have demonstrated that low-molecular-weight-heparin (LMWH) is superior to vitamin K antagonist (VKA) in preventing recurrent venous thromboembolism (VTE) in patients with cancer-associated VTE, guidelines now recommend LMWH monotherapy in this setting. We evaluated whether this shift resulted in improved outcomes in routine clinical practice. We performed a cohort study of consecutive patients with cancer-associated VTE during 2001 and 2010. We compared the risks for recurrent VTE, major bleeding and mortality between patients diagnosed before and after 2008 during a 6-month routine follow-up. A total of 381 patients were included, of which 234 (61.4%) were diagnosed before 2008. Before 2008, 23% of the patients were treated with LMWH; thereafter, this percentage was higher: 67%. The 6-month incidence for recurrent VTE was 8.6% in patients diagnosed before 2008 versus 7.5% for patients diagnosed after 2008 (risk difference [RD]: -1.1%; 95% confidence interval [CI]: -6.3, 5.3). The respective risks for major bleeding were 6.4 versus 4.8% (RD: -1.6%; 95% CI: -3.8 to 5.8), and 39.7 versus 41.5% (RD: 1.8%; 95% CI: -8.8, 12) for overall mortality. The mean time in therapeutic range (TTR) of patients treated with VKA was 61%. Despite a clear shift toward LMWH as agent of choice for cancer-associated VTE, we did not observe a clear improvement in terms of recurrent VTE and bleeding complications.

Background: After diagnosis of cancer-associated VTE, guidelines recommend considering the continuation of anticoagulant treatment until the patient is cured of cancer, although the safety of stopping anticoagulant treatment after the patient is cured has never been evaluated., Methods: We conducted a cohort study in consecutive patients in whom cancer-associated VTE was diagnosed at the Leiden University Medical Center between January 2001 and January 2010 and monitored for the effect of cancer treatment, occurrence of recurrent VTE, major hemorrhage, and death., Results: Of the 358 patients with cancer-associated VTE, anticoagulant treatment was continued until the death of 207 patients. In another 12 patients anticoagulant treatment was continued because of an alternative indication despite their being cured of cancer. Anticoagulant treatment was stopped in 50 patients for reasons other than major hemorrhage despite active cancer, in 21 patients after major hemorrhage, and in 68 patients after they had been cured of cancer. Among these 68 patients, 10 patients received a diagnosis of symptomatic recurrent VTE during a cumulative follow-up of 311 years, resulting in an incidence rate of 3.2 per 100 patient-years (95% CI, 1.5-5.9). Seven of these 10 patients with recurrent VTE experienced a cancer relapse during follow-up. For the 50 patients who stopped anticoagulant treatment despite active cancer the recurrent VTE incidence rate was 19 per 100 patient-years (11 events during 59 years of follow-up; 95% CI, 9.3-33)., Conclusions: Our data support the recommendation to stop anticoagulant treatment of cancer-associated VTE in patients cured of cancer. A cancer relapse seems to be a strong risk factor for recurrent symptomatic VTE., (Copyright © 2016 American College of Chest Physicians. Published by Elsevier Inc. All rights reserved.)

Unlabelled: ESSENTIALS: We performed a pooled analysis of 926 patients with cancer-associated incidental pulmonary embolism (IPE). Vitamin K antagonists (VKA) are associated with a higher risk of major hemorrhage. Recurrence risk is comparable after subsegmental and more proximally localized IPE. Our results support low molecular weight heparins over VKA and similar management of subsegmental IPE., Background: Incidental pulmonary embolism (IPE) is defined as pulmonary embolism (PE) diagnosed on computed tomography scanning not performed for suspected PE. IPE has been estimated to occur in 3.1% of all cancer patients and is a growing challenge for clinicians and patients. Nevertheless, knowledge about the treatment and prognosis of cancer-associated IPE is scarce. We aimed to provide the best available evidence on IPE management., Methods: Incidence rates of symptomatic recurrent venous thromboembolism (VTE), major hemorrhage, and mortality during 6-month follow-up were pooled using individual patient data from studies identified by a systematic literature search. Subgroup analyses based on cancer stage, thrombus localization, and management were performed., Results: In 926 cancer patients with IPE from 11 cohorts, weighted pooled 6-month risks of recurrent VTE, major hemorrhage and mortality were 5.8% (95% confidence interval [CI] 3.7-8.3%), 4.7% (95% CI 3.0-6.8%), and 37% (95% CI 28-47%). VTE recurrence risk was comparable under low molecular weight heparins (LMWH) and vitamin K antagonists (VKAs) (6.2% vs. 6.4%; hazard ratio [HR] 0.9; 95% CI 0.3-3.1), while 12% in untreated patients (HR 2.6; 95% CI 0.91-7.3). Risk of major hemorrhage was higher under VKAs than under LMWH (13% vs. 3.9%; HR 3.9; 95% CI 1.6-10). VTE recurrence risk was comparable in patients with an subsegmental IPE and those with a more proximally localized IPE (HR 1.1; 95% CI 0.50-2.4)., Conclusion: These results support the current recommendation to anticoagulate cancer-associated IPE with LMWH and argue against different management of subsegmental IPE., (© 2015 International Society on Thrombosis and Haemostasis.)

Background: With the routine use of advanced multi-slice CT scanners, pulmonary embolism (PE) is increasingly detected as an incidental finding among cancer patients. Although this generally leads to therapeutic interventions, the accuracy of diagnosing PE on routinely performed contrast enhanced CT scans is unknown., Methods: Consecutive cancer patients diagnosed with incidental PE were eligible for inclusion. Their CT images were reassessed in a blinded fashion by two thoracic radiologists. To ensure blindness, a total of 19 cancer staging CT images without PE were included. The inter-observer reliability for the presence of PE was calculated with use of Kappa statistics., Results: A total of 62 incidental PE patients (mean age 64years, 60% male) were included. All patients received anticoagulant treatment upon diagnosis. Level of agreement between the two expert readers was high: they disagreed on the presence of PE in only two patients (3.2%), resulting in a Kappa statistic of 0.93. After final consensus reading, it was concluded that the CT images of all 62 patients initially diagnosed with incidental PE were indeed positive for PE., Conclusions: This study indicates that an incidental PE diagnosis is reliable and highly reproducible, despite the suboptimal reading conditions of a non-dedicated scan protocol., (Copyright © 2015 Elsevier Ltd.

Introduction: Treatment of acute venous thromboembolism (VTE) in cancer patients is challenging, owing to a high risk of recurrent VTE and bleeding complications. The anticoagulants of choice are low molecular weight heparins (LMWHs), because of a proven higher efficacy than vitamin K antagonists (VKAs) and a similar bleeding profile. The recently introduced new oral anticoagulants (NOACs) have the potential to be alternative options for these patients, as these drugs share practical advantages with LMWH, are administered orally, and had similar efficacy to VKAs but a lower bleeding risk in phase 3 studies in the general VTE population., Methods: A systematic literature search was performed to identify phase 3 trials investigating NOACs for the treatment of VTE. The efficacy outcome was recurrent VTE, and the safety outcome was major and clinically relevant non-major bleeding. Pooled incidence rates and risk ratios (RRs) were calculated for cancer patients and non-cancer patients separately., Results and Discussion: Five studies were included, with 19 060 patients, of whom 973 (5.1%) had active cancer. The pooled incidence rates of recurrent VTE were 4.1% (95% confidence interval [CI] 2.6-6.0) in cancer patients treated with NOACs, and 6.1% (95% CI 4.1-8.5) in patients treated with VKAs (RR 0.66, 95% CI 0.38-1.2). The pooled incidence rates of major or non-major clinically relevant bleeding were 15% (95% CI 12-18) in cancer patients treated with NOACs, and 16% (95% CI 9.9-22) in patients treated with VKAs (RR 0.94, 95% CI 0.70-1.3). These results form a solid basis for the initiation of a head-to-head comparison of NOACs with LMWH in cancer patients., (© 2014 International Society on Thrombosis and Haemostasis.)

Cancer and hemostasis are strongly correlated and the development of venous thromboembolism (VTE) has a major adverse impact on the outcome of cancer patients. Treatment of cancer-associated VTE is far more challenging than treating VTE in the non-cancer population, as the clinical course of cancer patients is characterized by increased rates of both recurrent thromboembolic episodes and bleeding complications. This has led to the development of a distinct management approach towards VTE in patients with active cancer. Low-molecular-weight heparins (LMWHs) currently represent the therapeutic agent of choice, as a result of a proven higher efficacy compared to vitamin K antagonists (VKAs). However, as LMWHs require daily subcutaneous injections, weight-adjusted doses, and still confers high risks of recurrent VTE and bleeding complications, management of cancer-associated VTE warrants further optimization. In recent years several novel, target-specific oral anticoagulants have been introduced and evaluated in clinical trials. These new anticoagulants display several advantages compared to conventional anticoagulants. This review will evaluate their trial results up-to-date with a particular focus on the cancer patients included in these trials. The potential of these agents in the setting of cancer-associated VTE will be discussed and directions for future research will be provided., (Copyright © 2014 Elsevier Inc. All rights reserved.)

Venous thromboembolism (VTE) represents a common source of morbidity and mortality among patients with malignant disease. In this specific setting, the treatment of VTE is challenging as cancer patients display a high tendency to develop recurrent VTE, as well as anticoagulant-related bleeding complications. Low-molecular-weight heparins have been demonstrated to be more effective in the long-term prevention of recurrent VTE in cancer patients compared with conventional treatment with vitamin K antagonists. A limitation of this therapeutic approach includes the long-term requirement of daily subcutaneous injections, which may be burdensome to patients. Over the past decade, several novel oral anticoagulants have emerged, which can be administered in fixed doses without the need for monitoring. Clinical trials evaluating these agents for treatment in the general VTE population yielded promising results. This review summarizes the current management of cancer-associated VTE, overviews the trials that investigated the novel anticoagulant drugs for the treatment of acute VTE and discusses the potential of these novel agents for use in cancer patients., (© 2013 Elsevier Ltd.
