Abstract
Cancer-associated venous thromboembolism (VTE) significantly impacts morbidity and mortality. The introduction of direct oral anticoagulants over the past decade has revolutionized VTE treatment in patients with active cancer, offering potential advantages over traditional therapies. However, uncertainties persist regarding the optimal selection and dosage of anticoagulants, particularly in patients with specific risk factors for bleeding, such as certain cancer types (e.g., upper gastrointestinal cancer, genitourinary cancer, primary or metastatic brain tumor, and hematologic malignancies) and specific patient characteristics (e.g., renal dysfunction and thrombocytopenia). Recent data on the thrombotic risk associated with low thrombotic burden VTE, such as subsegmental pulmonary embolism and isolated distal deep vein thrombosis, underscore the need for updated management strategies in daily clinical practice. This review aims to explore these issues and highlight the evolving landscape of cancer-associated VTE management.

Abstract
BACKGROUND Patients with appropriately selected low-risk pulmonary embolism (PE) can be treated at home, although it has been controversial whether applies to patients with cancer, who are considered not to be at low risk.Methods and Results: The current predetermined companion report from the ONCO PE trial evaluated the 3-month clinical outcomes of patients with home treatment and those with in-hospital treatment. The ONCO PE trial was a multicenter, randomized clinical trial among 32 institutions in Japan investigating the optimal duration of rivaroxaban treatment in cancer-associated PE patients with a score of 1 using the simplified version of the Pulmonary Embolism Severity Index (sPESI). Among 178 study patients, there were 66 (37%) in the home treatment group and 112 (63%) in the in-hospital treatment group. The primary endpoint of a composite of PE-related death, recurrent venous thromboembolism (VTE) and major bleeding occurred in 3 patients (4.6% [0.0-9.6%]) in the home treatment group and in 2 patients (1.8% [0.0-4.3%]) in the in-hospital treatment group. In the home treatment group, there were no cases of PE-related death or recurrent VTE, but major bleeding occurred in 3 patients (4.6% [0.0-9.6%]), and 2 patients (3.0% [0.0-7.2%]) required hospitalization due to bleeding events. CONCLUSIONS Active cancer patients with PE of sPESI score=1 could be potential candidates for home treatment.

Abstract
Cancer-associated thrombosis (CAT) is a common complication in lung cancer patients. Lung cancer confers an increased risk of thrombosis compared to other solid malignancies across all stages of the disease. Newer treatment agents, including checkpoint immunotherapy and targeted agents, may further increase the risk of CAT. Different risk-assessment models, such as the Khorana Risk Score, and newer approaches that incorporate genetic risk factors have been used in lung cancer patients to evaluate the risk of thrombosis. The management of CAT is based on the results of large prospective trials, which show similar benefits to low-molecular-weight heparins (LMWHs) and direct oral anticoagulants (DOACs) in ambulatory patients. The anticoagulation agent and duration of therapy should be personalized according to lung cancer stage and histology, the presence of driver mutations and use of antineoplastic therapy, including recent curative lung surgery, chemotherapy or immunotherapy. Treatment options should be evaluated in the context of the COVID-19 pandemic, which has been shown to impact the thrombotic risk in cancer patients. This review focuses on the epidemiology, pathophysiology, risk factors, novel predictive scores and management of CAT in patients with active lung cancer, with a focus on immune checkpoint inhibitors.

Abstract
BACKGROUND Risk assessment models (RAMs) are relevant approaches to identify cancer outpatients at high risk of venous thromboembolism (VTE). Among the proposed RAMs, the Khorana (KRS) and the new-Vienna CATS risk scores have been externally validated in ambulatory patients with cancer. OBJECTIVES To test KRS and new-Vienna CATS scores in 6-month VTE prediction and mortality in a large prospective cohort of metastatic cancer outpatients during chemotherapy. PATIENTS/METHODS Newly diagnosed patients with metastatic non-small cell lung, colorectal, gastric, or breast cancers were analyzed (n = 1286). The cumulative incidence of objectively confirmed VTE was estimated with death as a competing risk and multivariate Fine and Gray regression. RESULTS Within 6 months, 120 VTE events (9.7%) occurred. The KRS and the new-Vienna CATS scores showed comparable c-stat. Stratification by KRS provided VTE cumulative incidences of 6.2%, 11.4%, and 11.5% in the low-, intermediate-, and high-risk categories, respectively (p = ns), and of 8.5% vs. 11.8% (p = ns) in the low- vs. high-risk group by the single 2-point cut-off value stratification. Using a pre-defined 60-point cut-off by the new-Vienna CATS score, 6.6% and 12.2% cumulative incidences were obtained in the low- and high-risk groups, respectively (p < 0.001). Furthermore, having a KRS ≥2 = or a new-Vienna CATS score >60 points was also an independent risk factor for mortality. CONCLUSION In our cohort, the 2 RAMs showed a comparable discriminating potential; however, after the application of cut-off values, the new-Vienna CATS score provided statistically significant stratification for VTE. Both RAMs proved to be effective in identifying patients at increased risk of mortality.

Abstract
This study aimed to identify clinical characteristics of cancer patients with incidental pulmonary embolism (IPE) and assess the variables associated with 30-day mortality in cancer patients with PE including symptomatic pulmonary embolism (SPE) and IPE. 6-Month mortality rate in cancer patients with SPE and IPE were also compared. We retrospectively analyzed electronic medical records of cancer patients with newly diagnosed PE between January 2016 and June 2021. We compared clinical and radiological characteristics in cancer patients with IPE and SPE and identified variables associated with the overall 30-day mortality on multivariate analysis. All patients were followed up for 6 months and survival analysis was performed by use of Kaplan-Meier. Five hundred and nine eligible cancer patients with pulmonary embolism were identified during the study period. IPE is associated with lower BMI, colorectal and pancreas cancers, stage III/IV of cancer, recent antiangiogenic therapy, central venous catheter (CVC) and chronic cardiac or respiratory disease compared to SPE. The factors associated with 30-day mortality included poor performance status, lung/pleura or upper gastrointestinal cancers, stage III/IV of cancer, previous VTE, oxygen saturation < 95%, lactic acid > 2 mmol/l and bilateral PE. The overall survival in patients with IPE at 6-month follow-up was similar to those diagnosed with SPE. The present study has allowed the identification of factors associated with 30-day mortality in cancer patients with IPE and SPE. We also found similar mortality rate in cancer patients with IPE compared with patients with SPE at 6-month follow-up.

Abstract
The purpose of this work was to compare the clinical characteristics, rate of recurrent venous thromboembolism (VTE), bleeding complications and mortality of incidental and symptomatic pulmonary embolism (PE) detected on computed tomography in patients with lung cancer. Clinical data of lung cancer patients with PE were obtained from the Department of Respiratory and Critical Care Medicine of Ningbo First affiliated hospital of Ningbo University during January 2016 and June 2021 and were reviewed retrospectively. We compared clinical and radiological characteristics in lung cancer patients with incidental PE (IPE) and symptomatic PE (SPE) and identified variables associated with the 1-year survival on multivariate Cox analysis. All patients were followed up for 1 year to compare the risks of recurrent VTE, bleeding complications, and mortality. Survival analysis was performed by use of Kaplan-Meier. A total of 223 lung cancer patients with PE were enrolled over the period. Of these, 117 (52%) patients had symptomatic whereas 106 (48%) patients had incidental PE. Those with IPE were more likely to have adenocarcinoma, VTE history, chronic respiratory disease and chemotherapy within 30 days prior to PE, while SPE was more frequently observed in patients with squamous cancer, concomitant VTE, performance status 0-1, chronic heart disease and major surgery within 30 days prior to PE. During 1 year of follow-up, recurrent VTE was diagnosed in 10 patients (9.3%) in lung cancer patients with IPE and 13 patients (11.2%) with SPE. The 12-month cumulative recurrent VTE incidence was 9.6% for patients with incidental and 11.4% for patients with symptomatic PE (P = .61). The 12-month cumulative incidences of major bleeding complications were also comparable in the 2 groups (8.1% for incidental patients and 9.8% for symptomatic patients; P = .62). However, the respective 12-month mortality risks were 34.6% and 30.2% in lung cancer patients with IPE and SPE respectively (P = .03). On multivariate Cox analysis, we found that IPE occurrence was an independent risk factor associated with 1-year mortality in lung cancer patients complicated with PE after adjusting for age and sex (HR 1.517; 95% CI: 1.366-1.684; P = .027). Our findings suggest that lung cancer patients diagnosed with and treated for incidental PE had a similar rate of recurrent VTE, and incidence of hemorrhagic complications, but a significantly higher 1-year cumulative mortality rate after PE compared to those with symptomatic PE. IPE may be a marker of poor prognosis.

Detection of Incidental Pulmonary Embolism on Conventional Contrast-Enhanced Chest CT: Comparison of an Artificial Intelligence Algorithm and Clinical Reports. AJR Am J Roentgenol 2022; 219:895-902.

Abstract
BACKGROUND. Artificial intelligence (AI) algorithms have shown strong performance for detection of pulmonary embolism (PE) on CT examinations performed using a dedicated protocol for PE detection. AI performance is less well studied for detecting PE on examinations ordered for reasons other than suspected PE (i.e., incidental PE [iPE]). OBJECTIVE. The purpose of this study was to assess the diagnostic performance of an AI algorithm for detection of iPE on conventional contrast-enhanced chest CT examinations. METHODS. This retrospective study included 2555 patients (mean age, 53.2 ± 14.5 [SD] years; 1340 women, 1215 men) who underwent 3003 conventional contrast-enhanced chest CT examinations (i.e., not using pulmonary CTA protocols) between September 2019 and February 2020. A commercial AI algorithm was applied to the images to detect acute iPE. A vendor-supplied natural language processing (NLP) algorithm was applied to the clinical reports to identify examinations interpreted as positive for iPE. For all examinations that were positive by the AI-based image review or by NLP-based report review, a multireader adjudication process was implemented to establish a reference standard for iPE. Images were also reviewed to identify explanations of AI misclassifications. RESULTS. On the basis of the adjudication process, the frequency of iPE was 1.3% (40/3003). AI detected four iPEs missed by clinical reports, and clinical reports detected seven iPEs missed by AI. AI, compared with clinical reports, exhibited significantly lower PPV (86.8% vs 97.3%, p = .03) and specificity (99.8% vs 100.0%, p = .045). Differences in sensitivity (82.5% vs 90.0%, p = .37) and NPV (99.8% vs 99.9%, p = .36) were not significant. For AI, neither sensitivity nor specificity varied significantly in association with age, sex, patient status, or cancer-related clinical scenario (all p > .05). Explanations of false-positives by AI included metastatic lymph nodes and pulmonary venous filling defect, and explanations of false-negatives by AI included surgically altered anatomy and small-caliber subsegmental vessels. CONCLUSION. AI had high NPV and moderate PPV for iPE detection, detecting some iPEs missed by radiologists. CLINICAL IMPACT. Potential applications of the AI tool include serving as a second reader to help detect additional iPEs or as a worklist triage tool to allow earlier iPE detection and intervention. Various explanations of AI misclassifications may provide targets for model improvement.

Abstract
Cancer-associated thrombosis (CAT) poses a significant disease burden and the incidence in Asian populations is increasing. Anticoagulation is the cornerstone of treatment, but can be challenging due to the high bleeding risk in some cancers and the high risk of recurrent venous thromboembolism (VTE) in patients with malignancies. Direct oral anticoagulants (DOACs) are well established as first-choice treatments for VTE in non-cancer patients, offering a more convenient and less invasive treatment option than low-molecular-weight heparin (LMWH). Asian patients have exhibited comparable efficacy and safety outcomes with other races in trials of DOACs for VTE in the general population. Although no specific data are available in Asian patients with CAT, results from randomized controlled trials of apixaban, edoxaban, or rivaroxaban versus the LMWH, dalteparin, indicate that DOACs are a reasonable alternative to LMWH for anticoagulation in Asian patients with CAT. This is further supported by analyses of real-world data in Asian populations demonstrating the efficacy and safety of DOACs in Asian patients with CAT. Apixaban, edoxaban, or rivaroxaban are recommended in the most recently updated international guidelines as first-line therapy for CAT in patients without gastrointestinal or genitourinary cancers and at low risk of bleeding. An increased risk of major gastrointestinal bleeding was evident with edoxaban or rivaroxaban, but not apixaban, versus dalteparin in the clinical trials, suggesting that apixaban could be a safe alternative to LMWH in patients with gastrointestinal malignancies. Determining the optimal anticoagulant therapy for patients with CAT requires careful consideration of bleeding risk, tumor type, renal function, drug-drug interactions, financial costs, and patients' needs and preferences.

[PMID: 36210612 DOI: 10.1111/ejh.13877] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2022] [Revised: 09/08/2022] [Accepted: 09/12/2022] [Indexed: 11/29/2022]
Abstract
BACKGROUND Clinical picture and outcome of incidental pulmonary embolism (iPE) compared to symptomatic pulmonary embolism (sPE) remain unclear. METHODS Demographics, recurrent venous thromboembolism (VTE), mortality, major bleeding, and clinically relevant nonmajor bleeding (CRNMB) were compared between iPE and sPE patients who were followed prospectively at Mayo Thrombophilia Clinic (March 1, 2013 to August 1, 2020). RESULTS Out of 3576 VTE patients, 1417 (39.6%) had PE: 562 (39.7%) iPE and 855 sPE. Patients with cancer were more likely to have iPE (400 iPE vs. 314 sPE) compared to those without cancer (162 iPE vs. 541 sPE). VTE recurrence rate (all per 100 person-years) was similar in all iPE and sPE patients (3.34 vs. 3.68, p = .50), with cancer (4.16 vs. 4.89, p = .370), and without cancer patients (0.89 vs. 2.80, p = .25). Higher mortality observed in all patients with iPE compared to sPE (46.45 vs. 23.47, p < .001) and with cancer (56.41 vs. 45.77, p = .03) became not significant after adjustment for age, antiplatelet therapy, metastases, and cancer location. Noncancer iPE patients had higher mortality (15.95 vs. 7.18, p = .006) even after adjustment (p = .05). The major bleeding rate was also higher in all patients iPE compared to sPE (7.10 vs. 3.68, p = .03), but not after adjustment (p = .974); higher major bleeding rate in noncancer patients (6.49 vs. 1.25, p = .007) remained significant after adjustment (.02). CRNMB rate was similar to iPE and sPE patients. CONCLUSION iPE represents a more serious clinical condition compared to sPE as indicated by the higher mortality and major bleeding but these differences reflect underlying comorbidities rather than the seriousness of the embolic event.

Abstract
Cancer-associated venous thromboembolism is a devastating complication of cancer and is associated with significant morbidity and mortality. The cornerstone of cancer-associated venous thromboembolism treatment is anticoagulation, and in recent years, there have been notable randomized clinical trials that have revealed insights into the efficacy and safety of direct oral anticoagulants and low-molecular-weight heparin in the treatment of cancer-associated thrombosis. Deciding on the ideal anticoagulation treatment plan for a patient with a cancer-associated thrombosis is a complex task that requires an understanding of clinical trial data, society guidelines, and, most importantly, consideration of many cancer-related, treatment-related, and patient-related factors. This article summarizes important factors to consider when deciding on anticoagulation therapy for a patient with cancer-associated thrombosis.

Abstract
Background There is scarce information regarding the prevalence and clinical impact of saddle pulmonary embolism (PE) in patients with cancer. Objectives This study aimed to assess the prevalence, clinical findings, and short-term outcomes of patients with cancer-related saddle PE including acute symptomatic and unsuspected events. Patients/Methods Consecutive patients with cancer-related PE (March 1, 2006-October 31, 2014) were retrospectively reviewed by a chest radiologist to assess PE burden and signs of right ventricular (RV) overload. The clinical outcomes within 30 days were evaluated according to saddle versus nonsaddle PE. Results Thirty-six (12%) out of 289 patients with newly diagnosed cancer-related PE presented with saddle PE. Saddle PE was found in 21 cases (58%) with acute symptomatic PE and the remaining 15 cases (42%) were found as unsuspected findings. Patients with saddle PE had more frequently experienced a previous thrombotic event (31 vs. 13%; p =0.008), and it occurred more frequently as an acute symptomatic event (58 vs. 39%; p =0.025) compared with those with nonsaddle PE. Signs of RV overload including RV/left ventricle ratio ≥1 (22 vs. 4%; p <0.001) and interventricular septum displacement (53 vs. 20%; p <0.001) were also more common in patients with saddle PE compared with nonsaddle PE. Overall, PE-related mortality, venous thromboembolism recurrence, and major bleeding within 30 days were found to be similar according to saddle versus nonsaddle PE. Conclusion Saddle PE is not uncommon in patients with cancer-related PE including in those with unsuspected PE. Similar 30-day outcomes were found according to saddle versus nonsaddle PE in our cohort.

Abstract
Venous thrombo-embolic (VTE) disease is a common cause of complications in patients with cancer and is the second most common cause of death in oncology patients other than the malignant disease. Whilst symptomatic VTE comprises the majority of such presentations to an emergency department (ED), incidental pulmonary embolism (IPE) is an increasingly frequent reason for attendance. Many studies report that the consequences of IPE do not differ significantly from those with symptomatic presentations and thus most guidelines recommend using the same approach. The complexity of treatment in cancer patients due to increased prevalence of co-morbidities, higher risk of bleeding, abnormal platelet and renal function, greater risk of VTE recurrence, and medications with the risk of anticoagulant interaction are consistent across patients with symptomatic and IPE. One of the initial challenges of the management of IPE is the design of a pathway that provides both patients and clinicians with a seamless journey from the radiological diagnosis of IPE to their initial clinical workup and management. Increased access to ambulatory care has successfully reduced ED utilisation and improved clinical outcomes in high-risk non-oncological populations, such as those with IPE. In this clinical review, we consider IPE management, its workup, the conundrums it may present for emergency physicians and the need to consider emergency ambulatory care for this growing cohort of patients.

Abstract
Pulmonary embolism (PE) is a leading cause of morbidity and mortality in patients with cancer. The clinical presentation and outcomes of PE range from an acute life-threatening condition requiring intensive care to a mild symptomatic condition associated with favorable outcomes and potentially candidate for early hospital discharge. The wide clinical spectrum of PE has led to the development of risk stratification models aimed at the triage of patients in emergency care departments and optimizing the utilization of health care resources. Incidental or unsuspected PE (UPE), detected during routine staging computed tomography scans, make up a significant proportion of this cohort among the oncology population. The present narrative review is aimed at examining the currently available PE risk assessment models developed for the general population and for patients with cancer including UPE. We include general recommendations for the daily care of patients with cancer-related PE and hypothesize on the factors that would potentially favor hospitalization with early discharge or ambulatory management in this setting.

Abstract
BACKGROUND Several trials have been conducted in the last decades that challenged the management of patients with acute pulmonary embolism (PE) in terms of diagnosis and treatment. Updated international clinical practice guidelines (CPGs) endorsed the evidence from these trials. The aim of this document was to adapt recommendations from existing CPGs to assist physicians in decision making concerning specific and complex scenarios related to acute PE. METHODS The flow for the adaptation procedure was first the identification of unsolved clinical issues in patients with acute PE (PICOs), then critically appraise the existing CPGs and choose the recommendations, which are the most applicable to these specific and complex scenarios. RESULTS Five PICOs were identified and CPGs appraisal was performed. Concerning diagnosis of PE when computed tomographic pulmonary angiography is not available/contraindicated and d-dimer is less specific, perfusion lung scan is the preferred option in the majority of clinical scenarios. For the treatment of PE when relevant clinical conditions like pregnancy or severe renal failure are present heparin is to be used. Poor evidence and low-level recommendations exist on the best bleeding prediction rule in patients treated for PE. The duration of anticoagulation needs to be tailored concerning the presence of predisposing factors for index PE and the consequent risk for recurrence. Finally, recommendations on the opportunity to screen for cancer and thrombophilia patients without recognized thrombosis risk factors for PE are reported. Overall, 35 recommendations were endorsed and the rationale for the selection is reported in the main text. CONCLUSION By the use of proper methodology for the adaptation process, this document offers a simple and updated guide for practicing clinicians dealing with complex patients.

Abstract
Objective Cancer is well known as the most important risk factor for the emergence of pulmonary embolism (PE). The incidence of incidental PE (IPE) has increased with widely use of multi-detector-row computed tomography (CT) technology. Simultaneously, more new cancer patients diagnosed concomitantly with IPE are found. No study has examined the presentation and prognosis of incidental pulmonary embolism (IPE) in gastric cancer patients. The aim of this study was to analyse prognostic factors in patients with advanced gastric cancer complicated with IPE. Patients and Methods Ninety patients with histologically confirmed advanced gastric adenocarcinoma diagnosed with IPE were enrolled. Continuous variables were compared using Student’s t-test or the Mann–Whitney U-test if non-normally distributed. The Chi-squared test (or Fisher’s exact test where appropriate) was used to compare categorical variables. The Kaplan–Meier method and the Log rank test were used for survival analysis. Independent prognostic factors for survival were determined using a Cox proportional hazards model. A two-sided P-value < 0.05 was considered statistically significant. Results Nineteen patients were diagnosed with IPE concomitantly with gastric cancer. Concurrence of gastric cancer and IPE, lack of anticoagulation therapy, and location of IPE were associated with survival. After adjusting for age and sex, the concurrence of gastric cancer and IPE, lack of anticoagulation, and central IPE independently influenced the survival of advanced gastric cancer patients with IPE. Subgroup analysis of patients with peripheral pulmonary embolisms confirmed that anticoagulant therapy provided a survival benefit. Conclusion Concurrence of gastric cancer and IPE may be a prognostic factor for advanced gastric cancer patients with IPE.

Abstract
Cancer associated thrombosis (CAT) is an important cause of morbidity and mortality for patients with malignancy and varies by primary cancer type, stage and therapy. We aimed to characterize the incidence, risk factors, temporal trends and the effect on mortality of CAT. The California Cancer Registry was linked to the statewide hospitalization database to identify individuals with the 13 most common malignancies diagnosed 2005 -2017 and determine the 6 and 12-month cumulative incidence of CAT by venous thromboembolism (VTE) location, tumor type and stage after adjusting for competing risk of death. Cox proportional hazard regression models were used to determine risk factors associated with CAT and the effect of CAT on all-cause mortality. 942,019 patients with cancer were identified; 62,003 (6.6%) had an incident diagnosis of CAT. Patients with pancreatic, brain, ovarian, and lung cancer had the highest and patients with breast and prostate cancer had the lowest 12-month cumulative incidence of CAT. For most malignancies, men, those with metastatic disease and more co-morbidities, and African-Americans (vs. non-Hispanic Whites) were at highest risk for CAT. Patients diagnosed with cancer 2014-2017 had higher risk of CAT compared to those diagnosed 2005-2007. CAT was associated with increased overall mortality for all malignancies (HR ranges 1.89 - 4.79). The incidence of CAT increased over time and was driven by an increase in PE±DVT. CAT incidence varies based on tumor type and stage, and on individual risk factors including gender, race/ethnicity, and co-morbidities. For all tumor types CAT is associated with an increased mortality.

Abstract
BACKGROUND Patients with cancer have an increased risk of venous thromboembolism (VTE) and it is commonly detected incidentally. The outcomes and optimal management for patients with cancer and incidental VTE remain debated. OBJECTIVES We conducted a systematic review and meta-analysis to evaluate the outcomes in patients with cancer and incidentally detected VTE compared to those with symptomatic events. PATIENTS/METHODS We searched the electronic databases and included randomized controlled trials (RCTs) and observational studies reporting recurrent VTE, major bleeding events, and mortality in patients with cancer and incidental VTE compared to symptomatic VTE. RESULTS We included 23 studies for the systematic review: 3 RCTs and 20 observational studies. The meta-analysis of the 3 RCTs showed a significantly lower rate of VTE recurrence at 6 months in patients with incidental VTE compared to those with symptomatic VTE (relative risk [RR] 0.62, 95% confidence interval [CI] 0.44-0.87). The risk of major bleeding events at 6 months was numerically higher with incidental VTE compared to symptomatic VTE (RR 1.47, 95% CI 0.99-2.20). There was no difference in overall mortality. CONCLUSIONS Among patients with cancer, incidental VTE was associated with a lower rate of VTE recurrence compared to symptomatic VTE, with a trend in increased major bleeding events. The risk-benefit ratio of anticoagulation may differ between incidental and symptomatic events and should be considered in patient management.

Abstract
Clinicians have been more and more often encountering patients with venous thromboembolism (VTE), including pulmonary embolism and deep vein thrombosis, leading to the increased importance of VTE in daily clinical practice. VTE is becoming a common issue in Asian countries including Japan. The management strategies of VTE have changed dramatically in the past decade including the introduction of direct oral anticoagulants (DOACs). In addition, there have been several landmark clinical trials assessing acute treatment strategies including thrombolysis and inferior vena cava (IVC) filter. The current VTE guidelines do not recommend the routine use of thrombolysis or IVC filters based on recent evidence; Nevertheless, the prevalence of thrombolysis and IVC filter use in Japan was strikingly high. The novel profiles of DOACs with rapid onset of action and potential benefit of a lower risk for bleeding compared with vitamin K antagonist could make home treatment feasible and is safer even with extended anticoagulation therapy. One of the most clinically relevant issues for VTE treatment is optimal duration of anticoagulation for the secondary prevention of VTE. Considering recent evidence, optimal duration of anticoagulation should be determined based on the risk for recurrence as well as the risk for bleeding in an individual patient. Despite the recent advances for VTE management, there are still a number of uncertain issues that challenge clinicians in daily clinical practice, such as cancer-associated VTE and minor VTE including subsegmental pulmonary embolism and distal deep vein thrombosis, warranting future research. Several clinical trials are now ongoing for these issues, globally as well as in Japan. The current review is aimed to overview the recent advances in VTE management, describe the current status including some domestic issues in Japan, and discuss the future perspective of VTE.

Abstract
The direct-acting oral anticoagulant (DOAC) has become an alternative to low-molecular-weight heparin (LMWH) for treatment and prophylaxis of venous thromboembolism (VTE) in cancer patients. The clinicians are, however, faced with difficult decisions regarding DOAC treatment: Which patients cannot use DOACs? Should incidental VTE be treated similar to symptomatic VTE? Is it safe to give DOACs to patients with gastrointestinal or urogenital cancers? How about drug–drug interactions? Should all cancer patients receive thromboprophylaxis? Is arterial thrombosis a problem? The current article reviews the available literature regarding these questions and aims to provide practical solutions based on data from the clinical trials and new guidelines.

Abstract
Platelet disorders comprise heterogeneous diseases featured by reduced platelet counts and/or impaired platelet function causing variable bleeding symptoms. Despite their bleeding diathesis, patients with platelet disorders can develop transient or permanent prothrombotic conditions that necessitate prophylactic or therapeutic anticoagulation. Anticoagulation in patients with platelet disorders is a matter of concern because the bleeding risk could add to the hemorrhagic risk related to the platelet defect. This review provides an overview on the evidence on anticoagulation in patients with acquired and inherited thrombocytopenia and/or platelet dysfunction. We summarize tools to evaluate and balance bleeding- and thrombotic risks and describe a practical approach on how to manage these patients if they have an indication for prophylactic or therapeutic anticoagulation.

Abstract
Venous thromboembolism (VTE) is a common complication in patients with cancer. The risk of emergent VTE is four- to seven-fold higher in cancer patients compared to non-cancer patients. Although the therapeutic armamentarium for cancer-associated VTE has been recently implemented, anticoagulant treatment remains challenging because of the increased risk of recurrent VTE and bleeding. Several international societies and expert panels released clinical practice guidelines on VTE treatment which are mostly focused on the general cancer population. Nevertheless, recommendations for the management of VTE in patients with peculiar clinical presentations are inconsistent and remain elusive due to the lack of pertinent evidence. The challenging clinical scenarios include, among others, patients with thrombocytopenia, renal impairment, gastrointestinal cancer, primary or metastatic brain cancer, distal thrombosis of the lower extremities, catheter-related VTE, splanchnic thrombosis, incidental VTE, extreme body weight, recurrent VTE during treatment, as well as the optimal duration of anticoagulant treatment in patients with active disease who have received 3 to 6 months of anticoagulation. Herein, we present a critical overview on VTE management in these challenging clinical settings, discuss potential approaches, and include some calls to action for future clinical research.

Abstract
Cancer therapy and progress in quality of imaging technologies for cancer surveillance and staging are in cause for the increase incidence of smaller incidental pulmonary embolism (PE). The clinical significance of incidental subsegmental pulmonary embolism (SSPE) is hard to define, balancing between possible false positive result, hypercoagulability signal, and truly venous thromboembolism (VTE) event. Evidence for optimal management of such findings are largely extrapolated from symptomatic SSPE in non-cancer patients and from symptomatic, more proximal PE in cancer patients. Current practice guidelines vary but some suggest withholding anticoagulation in selected patients. However, most SSPEs, incidental or not, should be treated as any other cancer-associated PE due to likely similar prognosis. Choice and duration of anticoagulation are extended from existing knowledge on more proximal PE.

Abstract
Cancer is a hypercoagulable state with an associated increased risk of venous thromboembolism (vte) that is further amplified in individuals who undergo chemotherapy. Compared with patients having cancer alone or vte alone, patients who develop cancer-associated vte have a significantly poorer prognosis. The risks of recurrent vte despite appropriate anticoagulation therapy and of bleeding are also higher in patients with cancer than in those without. For those reasons, the prevention and appropriate management of cancer-associated thrombosis is of paramount importance. Although low-molecular-weight heparin has been the standard of care for the prevention and treatment of cancer-associated thrombosis, direct oral anticoagulants are increasingly being adopted as an effective and safe alternative.

Abstract
Up to 20% of cancer patients will develop some manifestation of venous thromboembolic disease (VTD) during their clinical course. VTD greatly impacts morbidity, mortality, quality of life and pharmaceutical expenditure. In addition, both thrombotic relapse and major haemorrhages derived from VTD treatment are more likely in oncological patients. To make the decision to establish secondary thromboprophylaxis as an indefinite treatment in these patients, it is important to review all the risk factors involved, whether related to the disease, the patient or the prior thrombotic event. The objectives of this consensus of the Spanish Society of Internal Medicine (Sociedad Española de Medicina Interna-SEMI) and the Spanish Society of Medical Oncology (Sociedad Española de Oncología Médica-SEOM) are to establish recommendations that help assess the risk of recurrence of VTD and haemorrhagic risk in patients with cancer, as well as to analyse the evidence that exists on the currently available drugs, which will allow the establishment of a protocol for shared decision-making with the informed patient.

Prognostic Significance of Incidental Deep Vein Thrombosis in Patients with Cancer Presenting with Incidental Pulmonary Embolism. Cancers (Basel) 2020; 12:cancers12082267.

Abstract
In symptomatic acute pulmonary embolism (PE), the presence of deep vein thrombosis (DVT) is a risk factor for 30- and 90-day mortality. In patients with cancer and incidental PE, the prognostic effect of concomitant incidental DVT is unknown. In this retrospective study, we examined the effect of incidental DVT on all-cause mortality in such patients. Adjusted Cox multivariate regression analysis was used for relevant covariates. From January 2010 to March 2018, we included 200 patients (mean age, 65.3 ± 12.4 years) who were followed up for 12.5 months (interquartile range 7.4-19.4 months). Of these patients, 62% had metastases, 31% had concomitant incidental DVT, and 40.1% (n = 81) died during follow-up. All-cause mortality did not increase in patients with DVT (hazard ratio [HR] 1.01, 95% confidence interval [CI] 0.43-2.75, p = 0.855). On multivariate analysis, weight (adjusted HR 0.96, 95% CI 0.92-0.99, p = 0.032), and metastasis (adjusted HR 10.26, 95% CI 2.35-44.9, p = 0.002) were predictors of all-cause mortality. In conclusion, low weight and presence of metastases were associated with all-cause mortality, while presence of concomitant DVT was unrelated to poorer survival.

Abstract
This article describes 2 relatively rare, but complex situations in pulmonary embolism (PE): clot-in-transit (CIT), incidental PE (IPE). CIT describes a venous thromboembolism that has become lodged in the right heart. CIT is associated with high mortality and presents unique challenges in management. Incidental PE (IPE) describes PE diagnosed on imaging performed for another indication. The treatment is complex because there is often a disconnect between the PE severity on imaging and lack of severity of the clinical presentation. We summarize the available literature and aid clinicians as they manage patients with PE across the clinical severity spectrum.

Abstract
BACKGROUND Low-molecular-weight-heparins (LMWHs) have been established for the treatment of cancer-associated venous thromboembolism (VTE). Recently published randomized controlled trials (RCTs) have compared direct oral anticoagulants (DOACs) with LMWHs. The aim of this systematic review and meta-analysis was to evaluate efficacy and safety of DOACs versus LMWHs and update the evidence for treatment of VTE in cancer. METHODS Biomedical databases were screened for RCTs evaluating DOACs for cancer-associated VTE. Primary efficacy and safety outcomes of this meta-analysis were recurrent VTE and major bleeding at 6 months. Secondary outcomes comprised clinically relevant nonmajor bleeding (CRNMB), major gastrointestinal (GI) and genitourinary bleeding, mortality, fatal bleeding/pulmonary embolism, and treatment discontinuation rate. We performed prespecified subgroup analyses. Pooled relative risk (RR) and 95% confidence intervals (CIs) were obtained by the Mantel-Haenszel method within a random-effect model. RESULTS We screened 759 articles and included 4 RCTs (n = 2894). DOACs significantly reduced recurrent VTEs compared to LMWHs (5.2% vs 8.2%; RR, 0.62 [95% CI, 0.43-0.91]), but were associated with a nonsignificant increase in major bleedings (4.3% vs 3.3%; RR, 1.31 [95% CI, 0.83-2.08]) and a significant increase in CRNMB (10.4% vs 6.4%; RR, 1.65 [95% CI, 1.19-2.28]). Mortality risks were comparable between groups (RR, 0.99 [95% CI, 0.83-1.18]). Preterm treatment discontinuation was less common with DOACs (RR, 0.88 [95% CI, 0.81-0.96]). Major bleeding was more frequent in patients with GI cancer treated with DOACs (RR, 2.30 [95% CI, 1.08-4.88]). CONCLUSION In patients with cancer-associated VTE, DOACs are more effective in preventing recurrent VTE compared to LMWH. However, risk of bleeding is increased with DOACs, especially in patients with GI cancer.

Abstract
BACKGROUND Previous studies suggest isolated distal deep vein thrombosis (IDDVT) has a self-limited clinical course. However, these studies excluded cancer patients, who remain a high-risk population. In addition, studies to evaluate the long-term clinical outcomes of IDDVT in cancer patients have been limited. Here, we report outcomes from our experience in treating cancer-associated IDDVT versus proximal venous thromboembolism (VTE). METHODS We prospectively evaluated a cohort of patients referred to our cancer-associated thrombosis clinic from August 2014 through May 2018. We compared clinical characteristics, anticoagulation prescription, VTE recurrence, overall survival, major bleeding, and subsequent hospital admission between cancer patients with IDDVT and proximal VTE. A propensity score matching method was used to reduce bias from confounding variables. RESULTS Of 1100 patients referred to the clinic, 124 IDDVT and 178 proximal VTE events were analyzed. After propensity score matching, 96 patients were included in each cohort. There was no difference in the rate of recurrent VTE between cancer patients with proximal VTE vs IDDVT, with or without matching (matched: hazard ratio [HR], 0.77; 95% confidence interval [CI], 0.31-1.92; P = .58). There was no difference in overall survival between cancer patients with proximal VTE vs. IDDVT with or without matching (matched: HR, 1.18; 95% CI, 0.77-1.82; P = .45). Furthermore, subsequent hospital admissions and major bleeding events were similar between patients with proximal VTE events versus IDDVT. CONCLUSIONS Cancer patients with IDDVT have similar outcomes as their proximal counterparts, including rate of recurrence and overall survival. These findings suggest treatment of cancer-associated IDDVT should mirror treatment of proximal events.

Abstract
Patients with cancer are at an increased risk of symptomatic venous thromboembolism (VTE). In addition, an increasing number of patients with incidental thromboembolic events have been recorded in clinical practice. Therapeutic anticoagulation is crucial to prevent thrombus progression and reduce risk of recurrence; however, this comes at the price of an increased bleeding risk, which necessitates a personalised approach to choose the most appropriate type of therapy. Over the last decade, low-molecular-weight heparin has been the preferred anticoagulant agent for patients with cancer-associated thrombosis due to better efficacy and similar safety profile compared with vitamin K antagonists. While direct oral anticoagulants (DOAC) have emerged as new option for treatment of VTE in a general population, only limited data have been available specifically for patients with cancer until recently. Randomised, controlled trials have now been published, establishing DOAC as an alternative for the treatment of cancer-associated thrombosis. However, the improvement in the therapeutic armamentarium is accompanied by a number of special considerations. For instance, risk of bleeding is elevated in patients with cancer-associated VTE receiving DOAC, especially in certain tumour types (eg, gastrointestinal), and no guidance exists regarding their use in patients with severe thrombocytopaenia. Furthermore, DOAC are prone to certain drug-drug interactions and their effect might be altered due to nausea and vomiting in patients receiving chemotherapy. Here, we provide guidance on how to treat cancer-associated VTE and how new evidence from randomised controlled trials can be implemented in clinical practice. There are still clinical scenarios where robust evidence is lacking and treatment recommendations are based on extrapolations from other populations or expert opinion only. Therefore, additional research in special subpopulations is needed to optimise management of patients in challenging clinical scenarios.

Abstract
The American Society of Clinical Oncology (ASCO) recently updated their clinical practice guidelines. The most novel aspect of this update is represented by the introduction of DOACs as pharmacological options both for prophylaxis and treatment of VTE in patients with cancer. The heterogeneity of the cancer population in terms of type and stage of the malignancy, presence of comorbidities, and variability in cancer treatments and prognosis represent the major challenge of managing VTE in patients with cancer. The use of VTE prophylaxis is currently recommended in cancer patients admitted to the hospital for an acute illness or reduced mobility, but no sufficient information is available on the risk of bleeding during thromboprophylaxis. Concerning the thromboprophylaxis in ambulatory cancer patients receiving chemotherapy, further refinement of existing risk models or development of new models are needed for improving risk stratification to identify high-risk cancer patients. The updated ASCO guidelines recommend the use of DOACs (edoxaban and rivaroxaban) for treatment of VTE in patients with cancer. However, Major concerns on "real-life" use of DOACs in patients with cancer are highlighted especially for the bleeding risk in patients with gastrointestinal cancers and the potential drug-drug interactions with specific anticancer therapies. CONCLUSIONS: Uncertainties to the updated ASCO guidelines remain concerning a number of indications on prophylaxis and treatment due to the limited evidence available. These limitations determine the low strength of the recommendations. The ongoing studies will contribute to refine the best management of patients with cancer-associated VTE.

Abstract
INTRODUCTION In recent years, a hypothesis has been raised that people with tuberculosis are at risk for developing venous thromboembolism (VTE). However, much remains to be understood about the interplay between VTE and tuberculosis. Therefore, through a global systematic review and meta-analysis, the current study aims at investigating the association between exposure to active tuberculosis and risk of VTE, and determining the prevalence and incidence of VTE in people with active tuberculosis. METHODS AND DESIGN We will include cohort studies, case-control and cross-sectional studies performed among adults (>15 years) with active tuberculosis. EMBASE, Medline, Global Index Medicus and Web of Knowledge will be searched for relevant records published until 31 August 2019, without any language restriction. The review will be reported according to the Meta-analysis Of Observational Studies in Epidemiology guidelines. After screening of titles and abstracts, study selection, data extraction and risk of bias assessment; we shall assess the studies individually for clinical and statistical heterogeneity. Random-effect meta-analysis will be used to pool studies judged to be clinically homogenous. The Egger's test and visual inspection of funnel plots will be used to assess publication bias. Results will be presented by country and region. ETHICS AND DISSEMINATION Since primary data are not collected in this study, ethical approval is not required. This review is expected to provide relevant data on the epidemiology of VTE in people with tuberculosis. The final report will be published in a peer-reviewed journal.

Abstract
Splanchnic vein thrombosis (SVT) including portal, mesenteric, splenic vein thrombosis and the Budd-Chiari syndrome, is a manifestation of unusual site venous thromboembolism. SVT presents with a lower incidence than deep vein thrombosis of the lower limbs and pulmonary embolism, with portal vein thrombosis and Budd-Chiari syndrome being respectively the most and the least common presentations of SVT. SVT is classified as provoked if secondary to a local or systemic risk factor, or unprovoked if the causative trigger cannot be identified. Diagnostic evaluation is often affected by the lack of specificity of clinical manifestations: the presence of one or more risk factors in a patient with a high clinical suspicion may suggest the execution of diagnostic tests. Doppler ultrasonography represents the first line diagnostic tool because of its accuracy and wide availability. Further investigations, such as computed tomography and magnetic resonance angiography, should be executed in case of suspected thrombosis of the mesenteric veins, suspicion of SVT-related complications, or to complete information after Doppler ultrasonography. Once SVT diagnosis is established, a careful patient evaluation should be performed in order to assess the risks and benefits of the anticoagulant therapy and to drive the optimal treatment intensity. Due to the low quality and large heterogeneity of published data, guidance documents and expert opinion could direct therapeutic decision, suggesting which patients to treat, which anticoagulant to use and the duration of treatment.

Usefulness of Simplified Pulmonary Embolism Severity Index Score for Identification of Patients With Low-Risk Pulmonary Embolism and Active Cancer: From the COMMAND VTE Registry. Chest 2019; 157:636-644. [PMID: 31605702 DOI: 10.1016/j.chest.2019.08.2206] [Citation(s) in RCA: 28] [Impact Index Per Article: 5.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/25/2019] [Revised: 08/07/2019] [Accepted: 08/31/2019] [Indexed: 12/15/2022] Open
Abstract
BACKGROUND The simplified Pulmonary Embolism Severity Index (sPESI) score is a practical score for identification of patients with low-risk pulmonary embolism (PE), although it has not been applied in patients with active cancer. The current study aimed to evaluate the usefulness of the sPESI score in patients with PE and active cancer. METHODS The COMMAND VTE Registry is a multicenter registry enrolling consecutive patients with acute symptomatic VTE. The current study population consisted of 368 patients with PE and active cancer. The 30-day clinical outcomes were compared between patients with sPESI score = 1 and patients with sPESI scores ≥ 2. RESULTS Overall, 37 patients (10%) died during the 30 days after diagnosis. The cumulative 30-day incidences of mortality, and PE-related death, were lower in patients with sPESI score = 1 than in patients with sPESI scores ≥ 2 (6.3% vs 13.1%; log-rank P = .03; and 0.7% vs 3.9%; log-rank P = .046). Among patients with sPESI score = 1, the predominant cause of death was cancer. There were no significant differences in the cumulative 30-day incidence of recurrent VTE and major bleeding between the two groups (3.9% vs 5.6%; log-rank P = .46; and 6.4% vs 4.5%; log-rank P = .45). CONCLUSIONS Among patients with PE and active cancer, patients with sPESI score = 1 had a lower 30-day mortality rate compared with patients with sPESI scores ≥ 2, and they showed very low PE-related mortality risk, although the overall mortality rate remained high because of cancer-related mortality. They also showed relatively high risks for recurrence and major bleeding, suggesting the need for careful follow-up.

Abstract
Background Incidental pulmonary embolism (IPE) is frequently detected in of cancer patients undergoing CT scans for staging work up or treatment response evaluation. Nevertheless, the optimal management of IPE remains unknown. Thus, we aimed to evaluate the clinical manifestations of IPE in cancer patients and to compare the clinical prognosis according to anticoagulation therapy. Methods We retrospectively analyzed medical records of cancer patients with newly diagnosed PE between March 2010 and December 2013. Baseline demographics, comorbidities, cancer status and clinical presentation of PE were recorded. We compared all cause death, recurrent venous thromboembolism and clinically relevant bleeding events in those with PE. Survival analysis was performed to assess effect of anticoagulation on IPE. Results Among 703 cancer patients diagnosed with PE, IPE was identified in 474 (67.3%) patients. Compared to symptomatic patients, those with IPE had more advanced malignancy, were more likely to be on current chemotherapy at the time of IPE diagnosis. These patients tend to have smaller embolic burden, as demonstrated by the lower rate of bilateral lung involvement and RV dysfunction. While symptomatic PE showed better survival with anticoagulation (median survival 6.0 vs. 17.3 months, p = 0.003), anticoagulation did not result in significant survival benefit in IPE (median survival 15.1 vs. 21.3, p = 0.225). However, in subgroup analysis, there was significant improvement in survival with anticoagulation in patients with proximal IPE (median survival 12.2 vs. 23.4 months, p = 0.023), but not in patients with distal IPE (21.2 vs. 15.1, p = 0.906). Conclusions In cancer patients who were diagnosed with IPE, the overall survival was different according to the embolic burden and anticoagulation therapy.

Abstract
ABSTRCT The purpose of this study was to evaluate the efficacy and safety of rivaroxaban for the treatment of cancer-associated venous thromboembolism (VTE).We performed a retrospective chart review of cancer patients with a pulmonary embolism, deep vein thrombosis, or both. Our analysis included all patients who received rivaroxaban from March 2013 to June 2016 at the Hemato-Oncology Division at the Pusan National University Hospital in Korea.Preliminary results identified 123 patients with a history of cancer that were treated with rivaroxaban. The average duration of rivaroxaban therapy was 95.25 days. While 35 patients had resolved VTE after the initiation of rivaroxaban, only one patient had it recur on rivaroxaban treatment. Major bleeding was observed in 6 (4.9%) patients and minor bleeding in 12 (9.8%) patients. The majority of bleeding events occurred spontaneously and most incidences of bleeding could be treated conservatively. Recurrence and major bleeding events on rivaroxaban were relatively low despite the fact that many patients had metastatic disease. Among 52 patient deaths (42.3%), none were due to VTE or bleeding complications; the cause of death in the majority of cases was cancer progression.Rivaroxaban is effective and safe for the treatment of cancer-associated VTE.

Abstract
Venous thromboembolism (VTE) is a common complication for cancer patients. VTE-associated risk varies according to the type of tumor disease. Head and neck cancer is a common cancer worldwide, and most tumors are squamous cell carcinomas due to tobacco and alcohol abuse. The risk of VTE associated with head and neck (H&N) cancer is considered empirically low, but despite the high incidence of H&N cancer, few data are available on this cancer; thus, it is difficult to state the risk of VTE. Our review aims to clarify this situation and tries to assess the real VTE risk associated with H&N cancer. We report that most clinical studies have concluded that there is a very low thrombosis risk associated with H&N cancer. Even with the biases that often exist, this clinical review seems to confirm that the risk of VTE was empirically hypothesized. Furthermore, we highlight that H&N cancer has all the biological features of a cancer associated with a high thrombosis risk, including a strong expression of procoagulant proteins, modified thrombosis/fibrinolysis mechanisms, and secretions of procoagulant microparticles and procoagulant cytokines. Thus, this is a paradoxical situation, and some undiscovered mechanisms that could explain this clinical biological ambivalence might exist.

Abstract
PURPOSE Pulmonary embolism is incidentally diagnosed in up to 5% of patients with cancer on routine imaging scans. The clinical relevance and optimal therapy for incidental pulmonary embolism, particularly distal clots, is unclear. The aim of the current study was to assess current treatment strategies and the long-term clinical outcomes of incidentally detected pulmonary embolism in patients with cancer. PATIENTS AND METHODS We conducted an international, prospective, observational cohort study between October 22, 2012, and December 31, 2017. Unselected adults with active cancer and a recent diagnosis of incidental pulmonary embolism were eligible. Outcomes were recurrent venous thromboembolism, major bleeding, and all-cause mortality during 12 months of follow-up. Outcome events were centrally adjudicated. RESULTS A total of 695 patients were included. Mean age was 66 years and 58% of patients were male. Most frequent cancer types were colorectal (21%) and lung cancer (15%). Anticoagulant therapy was initiated in 675 patients (97%), of whom 600 (89%) were treated with low-molecular-weight heparin. Recurrent venous thromboembolism occurred in 41 patients (12-month cumulative incidence, 6.0%; 95% CI, 4.4% to 8.1%), major bleeding in 39 patients (12-month cumulative incidence, 5.7%; 95% CI, 4.1% to 7.7%), and 283 patients died (12-month cumulative incidence, 43%; 95% CI, 39% to 46%). The 12-month incidence of recurrent venous thromboembolism was 6.4% in those with subsegmental pulmonary embolism compared with 6.0% in those with more proximal pulmonary embolism (subdistribution hazard ratio, 1.1; 95% CI, 0.37 to 2.9; P = .93). CONCLUSION In patients with cancer with incidental pulmonary embolism, risk of recurrent venous thromboembolism is significant despite anticoagulant treatment. Patients with subsegmental pulmonary embolism seemed to have a risk of recurrent venous thromboembolism comparable to that of patients with more proximal clots.

Abstract
PURPOSE This pilot study assessed the independent and incremental value of 68Ga-V/Q PET/CT as compared with CT pulmonary angiography (CTPA) for the management of cancer patients with suspected acute pulmonary embolism (PE). METHODS All 24 cancer patients with suspected acute PE prospectively recruited underwent both 68Ga-V/Q PET/CT and CTPA within 24 h. PET/CT was acquired after inhalation of Galligas prepared using a Technegas generator and administration of 68Ga-macroaggregated albumin. Initially, PET/CT and CTPA scans were read independently with the reader blinded to the results of the other imaging study. CTPA and PET/CT were then coregistered and reviewed by consensus between a radiologist and nuclear medicine physician. The therapeutic management was established by the managing physician based on all available data. RESULTS The diagnostic conclusion was concordantly negative in 18 patients (75%). Of the six discordant diagnoses on independent reading, combined interpretation of V/Q PET/CTPA enabled a consensus conclusion in two patients, excluding PE in one and confirming PE in the other, similar to the initial diagnostic conclusion of the V/Q PET/CT. Of the remaining four patients, three had a single subsegmental thrombus on CTPA but a negative V/Q PET/CT scan, and two of these did not receive long-term anticoagulation and did not have a venous thromboembolic event during a 3-year follow-up period. The third patient, along with a patient with a positive V/Q PET/CT scan but a negative CTPA scan, presented with acute complications preventing any conclusions with regard to the appropriateness of the V/Q PET/CT results in the management of PE. Overall, V/Q PET had an impact on management in four patients (17%). CONCLUSION In this pilot study, we demonstrated the feasibility and potential utility of V/Q PET/CT for the management of patients with suspected PE. V/Q PET/CT may be of particular relevance in patients with equivocal findings or isolated subsegmental findings on CTPA, adding further discriminatory information to allow important decision-making regarding the use or withholding of anticoagulation. Given the other advantages of V/Q PET/CT (reduced acquisition time, low radiation dose), and with the increasing availability of 68Ga generators, PET/CT is a potential replacement for V/Q SPECT/CT imaging.

Abstract
Pulmonary embolism (PE) is the most feared clinical presentation of venous thromboembolism (VTE). Patients with PE have traditionally been treated in hospital; however, many are at low risk of adverse outcomes and current guidelines suggest outpatient treatment as an option. Outpatient treatment of PE offers several advantages, including reduced risk of hospital-acquired conditions and potential cost savings. Despite this, patients with low-risk PE are still frequently hospitalized for treatment. This narrative review summarizes current guideline recommendations for the identification of patients with low-risk PE who are potentially suitable for outpatient treatment, using prognostic assessment tools (e.g. the Pulmonary Embolism Severity Index [PESI] and simplified PESI) and clinical exclusion criteria (e.g. Hestia criteria) alone or in combination with additional cardiac assessments. Treatment options are discussed along with recommendations for the follow-up of patients managed in the non-hospital environment. The available data on outpatient treatment of PE are summarized, including details on patient selection, anticoagulant choice, and short-term outcomes in each study. Accumulating evidence suggests that outcomes in patients with low-risk PE treated as outpatients are at least as good as, if not better than, those of patients treated in the hospital. With mounting pressures on health care systems worldwide, increasing the proportion of patients with PE treated as outpatients has the potential to reduce health care burdens associated with VTE.

Abstract
BACKGROUND Ambulatory patients receiving systemic cancer therapy are at varying risk for venous thromboembolism. However, the benefit of thromboprophylaxis in these patients is uncertain. METHODS In this double-blind, randomized trial involving high-risk ambulatory patients with cancer (Khorana score of ≥2, on a scale from 0 to 6, with higher scores indicating a higher risk of venous thromboembolism), we randomly assigned patients without deep-vein thrombosis at screening to receive rivaroxaban (at a dose of 10 mg) or placebo daily for up to 180 days, with screening every 8 weeks. The primary efficacy end point was a composite of objectively confirmed proximal deep-vein thrombosis in a lower limb, pulmonary embolism, symptomatic deep-vein thrombosis in an upper limb or distal deep-vein thrombosis in a lower limb, and death from venous thromboembolism and was assessed up to day 180. In a prespecified supportive analysis involving the same population, the same end point was assessed during the intervention period (first receipt of trial agent to last dose plus 2 days). The primary safety end point was major bleeding. RESULTS Of 1080 enrolled patients, 49 (4.5%) had thrombosis at screening and did not undergo randomization. Of the 841 patients who underwent randomization, the primary end point occurred in 25 of 420 patients (6.0%) in the rivaroxaban group and in 37 of 421 (8.8%) in the placebo group (hazard ratio, 0.66; 95% confidence interval [CI], 0.40 to 1.09; P = 0.10) in the period up to day 180. In the prespecified intervention-period analysis, the primary end point occurred in 11 patients (2.6%) in the rivaroxaban group and in 27 (6.4%) in the placebo group (hazard ratio, 0.40; 95% CI, 0.20 to 0.80). Major bleeding occurred in 8 of 405 patients (2.0%) in the rivaroxaban group and in 4 of 404 (1.0%) in the placebo group (hazard ratio, 1.96; 95% CI, 0.59 to 6.49). CONCLUSIONS In high-risk ambulatory patients with cancer, treatment with rivaroxaban did not result in a significantly lower incidence of venous thromboembolism or death due to venous thromboembolism in the 180-day trial period. During the intervention period, rivaroxaban led to a substantially lower incidence of such events, with a low incidence of major bleeding.

Abstract
Cancer-associated venous thromboembolism (CAT) is a common complication associated with high morbidity and mortality. In accordance with major clinical trials comparing low-molecular-weight heparin (LMWH) with a vitamin K antagonist (VKA), LMWH is currently the standard treatment for CAT, owing to its efficacy for thrombosis recurrence and improved safety profile compared to VKA. Over the past few years, direct oral anticoagulants (DOACs) have emerged as potential alternative therapies to LMWH due to their convenient route of administration and predictable pharmacokinetics, but evidence for their use in CAT is inconclusive, as only a small fraction of the study populations in these trials had CAT. Recently, two large head-to-head trials comparing DOACs to LMWH in CAT patients reported comparable efficacies of DOACs with increased bleeding risk. Occasionally, CAT treatment can be challenging due to the heterogeneity of underlying malignancies and comorbidities. Renal insufficiency and gastrointestinal defects are the main obstacles in anticoagulant selection. Careful choice of treatment candidates and proper anticoagulant strategies are critical for the treatment of CAT; hence, more studies are required to address these challenges.

Abstract
Venous thromboembolism (VTE), which includes deep vein thrombosis and pulmonary embolism, is a common complication of cancer and is associated with significant morbidity and mortality. Several cancer-related risk factors contribute to the development of VTE including cancer type and stage, chemotherapy, surgery, and patient-related factors such as advanced age and immobilization. Patients with cancer frequently undergo diagnostic imaging scans for cancer staging and treatment response evaluation, which is increasing the underlying risk of VTE detection. The management of cancer-associated VTE is challenging. Over the years, important advances have been made and, recently, randomized controlled trials have been published helping clinicians' management of this patient population. In this review, we will discuss common cancer-associated VTE scenarios and critically review available evidence to guide treatment decisions.

Thromb Res 2018; 164 Suppl 1:S124-S129.

Abstract
Patients with active cancer have a heightened risk of venous thromboembolism (VTE). This risk is further increased by the initiation of chemotherapy. Although previous studies have suggested that the use of parenteral thromboprophylaxis in all ambulatory cancer patients receiving chemotherapy significantly decreases the rate of VTE, current clinical practice guidelines do not recommend routine use of thromboprophylaxis in this patient population. A major criticism of these studies has been the inclusion of patients at lower risk for VTE, which may have diluted the potential beneficial effect of the parenteral thromboprophylaxis. It is therefore imperative to appropriately risk stratify ambulatory cancer patients using a validated scoring system (e.g. Khorana risk score) in order to identify those most likely to benefit from thromboprophylaxis. Direct oral anticoagulants, such as apixaban, may offer a convenient and safe option for thromboprophylaxis. As such, AVERT will randomize 574 ambulatory cancer patients receiving chemotherapy who are at high-risk for VTE (as defined by a Khorana score of ≥2) to Apixaban 2.5 mg BID versus placebo. The primary study outcome will be the first episode of objectively documented symptomatic or incidental VTE (deep vein thrombosis and/or pulmonary embolism) within the first 6 months (180 days ± 3) following initiation of the blinded study drug for both intervention and placebo groups. The secondary safety outcomes include major bleeding, clinically relevant non-major bleeding, and overall survival rates. This study will hopefully offer evidence regarding the benefit of apixaban in ambulatory patients at high risk for VTE receiving chemotherapy.

Abstract
PURPOSE OF REVIEW This review aims to summarize the epidemiology, current pathophysiologic understanding, and state-of-the-art treatment of venous thromboembolism (VTE) in cancer patients. RECENT FINDINGS The risk of VTE varies among cancer patients. Recently introduced prediction models better identify those at high risk of VTE. New mechanisms underlying hypercoagulability in cancer have been uncovered. Initial data on the efficacy of direct oral anticoagulants (DOACs) compared with low-molecular weight heparin to treat VTE in patients with cancer are promising. However, they may be associated with higher risk of gastrointestinal bleeding. VTE causes significant morbidity and mortality in cancer patients. Our understanding of the mechanisms of VTE, including those associated with cancer treatments, has significantly grown. The assessment of the benefit/risk balance of VTE treatment remains challenging in many patients with cancer. The introduction of DOACs has expanded treatment options, but knowledge on their efficacy and safety is incomplete.

Abstract
BACKGROUND Cancer patients hospitalized for an acute medical illness are considered to be at high risk of venous thromboembolism (VTE). Information on bleeding and symptomatic VTE in these patients remains scant. The objectives of this study were to evaluate the incidence of bleeding and VTE during hospitalization and after discharge in a prospective cohort of hospitalized medically-ill cancer patients. METHODS Consecutive patients with active cancer admitted for an acute medical illness. The primary outcome was the incidence of clinically relevant bleeding. Secondary outcomes included symptomatic and incidentally detected VTE. Outcomes were recorded during hospitalization up to three months after discharge. RESULTS The study population consisted of 330 patients with a mean age of 73.2 (±12.1) years. During a median hospitalization of eight days, six patients (1.8%) developed a clinically relevant bleeding. Pharmacological thromboprophylaxis was administered to four of these six patients (66.6%), and 108 of 324 (33.3%) patients without bleeding. Twelve (3.6%) were diagnosed with VTE, of whom two had received thromboprophylaxis. In ten patients, VTE was detected incidentally. After discharge, 11 patients experienced major bleeding and two developed symptomatic VTE during a median follow-up of 92 days (range 19-110). Two thirds of all major bleeding events were gastrointestinal, and 87% occurred in patients with gastrointestinal or genitourinary cancer. CONCLUSIONS In patients with active cancer admitted for an acute medical illness, the risk of bleeding and symptomatic VTE appeared to be low during hospitalization. After discharge, the risk of bleeding was higher and significantly outweighed that of VTE.

Abstract
Essentials Cancer patients are at risk for venous thromboembolism (VTE). The risk of VTE in less advanced stage cancer on neoadjuvant chemotherapy is unclear. In over 7800 patients, we found a 7% pooled incidence of VTE during neoadjuvant therapy. Highest VTE rates were observed in patients with bladder and esophageal cancer. SUMMARY Background Venous thromboembolism (VTE) is a frequent complication in cancer patients receiving adjuvant treatment. The risk of VTE during neoadjuvant chemo-radiotherapy remains unclear. Objectives This systematic review evaluated the incidence of VTE in patients with cancer receiving neoadjuvant treatment. Methods MEDLINE and EMBASE databases were searched from inception to October 2017. Search results were supplemented with screening of conference proceedings of the American Society of Clinical Oncology (2009-2016) and the International Society of Thrombosis and Haemostasis (2003-2016). Two review authors independently screened titles and abstracts, and extracted data onto standardized forms. Results Twenty-eight cohort studies (7827 cancer patients, range 11 to 1398) were included. Twenty-five had a retrospective design. Eighteen cohorts included patients with gastrointestinal cancer, representing over two-thirds of the whole study population (n = 6002, 78%). In total, 508 of 7768 patients were diagnosed with at least one VTE during neoadjuvant treatment, for a pooled VTE incidence of 7% (95% CI, 5% to 10%) in the absence of substantial between-study heterogeneity. Heterogeneity was not explained by site of cancer or study design characteristics. VTE presented as pulmonary embolism in 22% to 96% of cases (16 cohorts), and it was symptomatic in 22% to 100% of patients (11 cohorts). The highest VTE rates were observed in patients with bladder (10.6%) or esophageal (8.4%) cancer. Conclusions This review found a relatively high incidence of VTE in cancer patients receiving neoadjuvant therapy in the presence of some between-study variation, which deserves further evaluation in prospective studies.

Abstract
Venous thromboembolism is a major complication in cancer patients. The basis for the strong association between cancer and thrombosis remains incompletely understood, and the optimal approaches to both the treatment and the prevention of cancer-associated thrombosis are evolving. Here we review several important topics related to cancer-associated thromboembolism, including the pathogenesis, prevention, and management of this disease. Wherever possible, we include evidence from clinical trials, including the results of recently published trials that compared direct oral anticoagulants to low-molecular-weight heparin for the treatment of cancer-associated thrombosis.
