Abstract
INTRODUCTION Patients with central nervous system malignancies have limited representation in studies evaluating DOACs for VTE treatment. This study evaluated the safety and efficacy of DOACs in comparison with LMWH for cancer-associated VTE in patients with primary brain tumors or secondary brain metastases. MATERIALS & METHODS In this multicenter, retrospective cohort study, adult patients with a diagnosis of primary brain tumor or secondary brain metastases who received either a DOAC or LMWH for treatment of cancer-associated VTE were evaluated. The primary outcome was the cumulative incidence of any intracranial hemorrhage within a 6-month period following the initiation of anticoagulation. Secondary outcomes included the cumulative incidence of any bleeding event, and recurrent VTE events. RESULTS Between January 1, 2012 and October 9, 2019, one-hundred eleven patients met inclusion criteria. The 6-month cumulative incidence of intracranial hemorrhage was 4.3% (95% CI, 0.74-13.2%) in the DOAC group, compared to 5.9% (95% CI, 1.5-14.9%) in the LMWH group (p = 0.61). The 6-month cumulative incidence of bleeding events was 14.3% (95% CI, 6.2-25.8%) in the DOAC group, compared to 27.8% (95% CI, 15.5-41.6%) in the LMWH group (p = 0.10). The 6-month cumulative incidence of recurrent VTE events was 5.6% in the DOAC group (95% CI, 1.5-14.2%), compared to 6.6% in the LMWH group (95% CI, 1.7-16.5%) (p = 0.96). No differences were found with respect to other secondary outcomes. CONCLUSION There were no significant differences in bleeding or recurrent VTE events between DOACs and LMWH. These findings suggest DOACs may be safe and effective for VTE treatment in this patient population.

Abstract
Background: Apixaban (2.5 mg) taken twice daily has been shown to substantially reduce the risk of venous thromboembolism (VTE) compared with placebo for the primary thromboprophylaxis of ambulatory patients with cancer who are starting chemotherapy and are at intermediate-to-high risk of VTE. We aimed to compare the health system costs and health benefits associated with primary thromboprophylaxis using apixaban with those associated with the current standard of care (where no primary thromboprophylaxis is given), from the perspective of Canada’s publicly funded health care system in this subpopulation of patients with cancer over a lifetime horizon. Methods: We performed a cost–utility analysis to estimate the incremental cost per quality-adjusted life-year (QALY) gained with primary thromboprophylaxis using apixaban. We obtained baseline event rates and the efficacy of apixaban from the Apixaban for the Prevention of Venous Thromboembolism in High-Risk Ambulatory Cancer Patients (AVERT) trial on apixaban prophylaxis. We estimated relative risk for bleeding, risk of complications associated with VTE treatment, mortality rates, costs and utilities from other published sources. Results: Over a lifetime horizon, apixaban resulted in lower costs to the health system (Can$7902.98 v. Can$14 875.82) and an improvement in QALYs (9.089 v. 9.006). The key driver of cost–effectiveness results was the relative risk of VTE as a result of apixaban. Results from the probabilistic analysis showed that at a willingness to pay of Can$50 000 per QALY, the strategy with the highest probability of being most cost-effective was apixaban, with a probability of 99.87%. Interpretation: We found that apixaban is a cost-saving option for the primary thromboprophylaxis of ambulatory patients with cancer who are starting chemotherapy and are at intermediate-to-high risk of VTE.

Abstract
Background There is a need for clinical outcome data of cerebral venous thrombosis (CVT) in cancer patients. We examined the recanalization, thrombosis recurrence and major bleeding during CVT treatment in a cancer exclusive adult population. Methods We performed a retrospective review of cancer associated CVT identified through an institutional data warehouse. The primary endpoint was radiological and comprised the evaluation of thrombus recanalization at 12 months. Secondary endpoints were clinical and included rates of bleeding complications and recurrence of CVT. Variables were compared across subgroups of study outcomes. The backward stepdown procedure was used to identify variables for the final logistic model regarding thrombosis and bleeding outcomes. Results The population included forty-five patients, slightly predominant of male adults (55.6%) with a median age of 54.5 years. Solid malignancies comprised 64.4% of cases. A total of 31 cases were treated with anticoagulation. CVT recanalization was documented in almost 60% of cases. The cerebral venous thrombosis recurrence or propagation rate at 12 months was 15.6%. Major bleeding complications were observed in 15 patients. Conclusions Our findings are suggestive of a narrow therapeutic index of anticoagulation in cancer-CVT. Careful monitoring of anticoagulation effect and bleeding complications are of utmost clinical relevance in cancer patients. Further larger and controlled studies are needed to confirm our observations.

Abstract
Purpose Patients with glioblastoma (GBM) or brain metastases (MET) and atrial fibrillation (AF) might be at an increased risk of intracranial hemorrhage (ICH) due to anticoagulation (AC). Our aim was to assess this risk. Methods Our institution’s database (from 2005 to 2017) was screened for patients with GBM or MET and AF with an indication for AC according to their CHA2DS2VASc stroke risk score (≥ 2). Required follow-up was at least 3 months. AC was either performed with heparins, phenprocoumon or non-Vitamin K antagonist oral anticoagulants. Applying the propensity score approach, patient cohorts (matched according to primary tumor, age, sex) were generated (GBM [or MET] with AF ± AC, GBM [or MET] without AF/AC, no GBM [or MET] but AF on AC). ICH was defined as clinical deterioration caused by new blood on imaging. A log rank test was performed to compare the risk for ICH between the three groups. Results In total, 104 patients were identified of which 49 with GBM (37% on AC) and 37 with MET (46% on AC) were successfully matched. Median follow up was 8.6 and 7.2 months, respectively. ICH occurred in 10.2% of GBM + AF and 12.2% GBM-AF, whereas 8% of patients with AF on AC suffered ICH (p = 0.076). 13.5% of patients with MET + AF had ICHs, in the controls it was 16% for MET-AF and 8% for AF on AC (p = 0.11). Conclusion AC did not seem to influence the incidence of ICH in patients with glioblastoma or brain metastases within follow up of just under 9 months.

Abstract
PURPOSE OF REVIEW Patients with brain tumors are susceptible to multiple complications that can affect their survival or quality of life. The scope of these complications is widening due to prolonged overall survival and improved therapies. In this review, we discuss the most common complications in this patient population focusing on the recent literature. We specifically concentrated on tumor-related epilepsy, vasogenic edema, infectious, vascular, chemotherapeutic, radiation, endocrine, and cognitive complications. RECENT FINDINGS Molecular biomarkers play a role in epileptogenicity in brain tumor patients, and anti-epileptic drugs may cause neuro-cognitive side effects independent of other factors. The pathophysiology of vasogenic edema remains complex and poorly understood. Limited data suggest that newer oral anticoagulants appear to be safe and effective in venous and arterial thromboembolic complications. Brain tumor patients are prone to a wide variety of complications, including some related to new therapies. Optimal management of these complications improves quality of life, and in some cases overall survival.

Abstract
Venous thromboembolism (VTE) is a common disease complication in cancer patients and the second cause of death after cancer progression. VTE management and prophylaxis are critical in cancer patients, but effective therapy can be challenging because these patients are at higher risk of VTE recurrence and bleeding under anticoagulant treatment. Numerous published studies report inconsistent implementation of existing evidence-based clinical practice guidelines (CPG), including underutilization of thromboprophylaxis, and wide variability in clinical practice patterns across different countries and various practitioners. This review aims to summarize the 2019 ITAC-CME evidence-based CPGs for treatment and prophylaxis of cancer-related VTE, which include recommendations on the use of direct oral anticoagulants specifically in cancer patients. The guidelines underscore the gravity of developing VTE in cancer and recommend the best approaches for treating and preventing cancer-associated VTE, while minimizing unnecessary or over-treatment. Greater adherence to the 2019 ITAC guidelines could substantially decrease the burden of VTE and improve survival of cancer patients.

Abstract
BACKGROUND There is increasing evidence to support extended thromboprophylaxis after colorectal surgery to minimize the incidence of postdischarge venous thromboembolic events. However, the absolute number of events is small, and extended thromboprophylaxis requires significant resources from the health care system. OBJECTIVE This study aimed to determine the cost-effectiveness of extended thromboprophylaxis in patients undergoing colorectal surgery for malignancy or IBD. DESIGN An individualized patient microsimulation model (1,000,000 patients; 1-month cycle length) comparing extended thromboprophylaxis (28-day course of enoxaparin) to standard management (inpatient administration only) after colorectal surgery was constructed. SETTINGS The sources for this study were The American College of Surgeons National Surgical Quality Improvement Project Participant User File and literature searches. OUTCOMES Costs (Canadian dollars), quality-adjusted life-years, and venous thromboembolism-related deaths prevented over a 1-year time horizon starting with hospital discharge were determined. The results were stratified by malignancy or IBD. RESULTS In patients with malignancy, extended prophylaxis was associated with higher costs (+113$; 95% CI, 102-123), but increased quality-adjusted life-years (+0.05; 95% CI, 0.04-0.06), resulting in an incremental cost-effectiveness ratio of 2473$/quality-adjusted life-year. For IBD, extended prophylaxis also had higher costs (+116$; 95% CI, 109-123), more quality-adjusted life-years (+0.05; 95% CI, 0.04-0.06), and an incremental cost-effectiveness ratio of 2475$/quality-adjusted life-year. Extended prophylaxis prevented 16 (95% CI, 4-27) venous thromboembolism-related deaths per 100,000 patients and 22 (95% CI, 6-38) for malignancy and IBD. There was a 99.7% probability of cost-effectiveness at a willingness-to-pay threshold of 50,000$/quality-adjusted life-year. To account for statistical uncertainty around variables, sensitivity analysis was performed and found that extended prophylaxis is associated with lower overall costs when the incidence of postdischarge venous thromboembolic events reaches 1.8%. LIMITATIONS Significant differences in health care systems may affect the generalizability of our results. CONCLUSIONS Despite the rarity of venous thromboembolic events, extended thromboprophylaxis is a cost-effective strategy. See Video Abstract at http://links.lww.com/DCR/A976. COSTO-EFECTIVIDAD DE LA TROMBOPROFILAXIS EXTENDIDA EN PACIENTES SOMETIDOS A CIRUGÍA COLORRECTAL DESDE UNA PERSPECTIVA DEL SISTEMA DE SALUD CANADIENSE:: Cada vez hay más pruebas que apoyen la tromboprofilaxis extendida después de la cirugía colorrectal para minimizar la incidencia de eventos tromboembólicos venosos después del alta hospitalaria. Sin embargo, el número absoluto de eventos es pequeño y la tromboprofilaxis extendida requiere recursos significativos del sistema médico.Determinar la rentabilidad (relación costo-efectividad) de la tromboprofilaxis extendida en pacientes sometidos a cirugía colorrectal por neoplasia maligna o enfermedad inflamatoria intestinal.Un modelo de microsimulación de paciente individualizado (1,000,000 de pacientes; ciclo de 1 mes) que compara la tromboprofilaxis extendida (curso de enoxaparina de 28 días) con el tratamiento estándar (solo para pacientes hospitalizados) después de la cirugía colorrectal.Archivo de usuario participante del Proyecto de Mejoramiento de la Calidad Quirúrgica del Colegio Nacional de Cirujanos Americanos (ACS-NSQIP) y búsquedas bibliográficas.Costos (en dólares Canadienses), años de vida ajustados por la calidad y muertes relacionadas con el tromboembolismo venoso prevenidas en un horizonte temporal de 1 año a partir del alta hospitalaria. Los resultados fueron estratificados por malignidad o enfermedad inflamatoria intestinal.En pacientes con neoplasias malignas, la profilaxis extendida se asoció con costos más altos (+113 $; IC del 95%, 102-123), pero con un aumento de la calidad de vida ajustada por años de vida (+0.05; IC del 95%, 0.04-0.06), lo que resultó en un incremento de relación costo-efectividad de 2473 $/año de vida ajustado por calidad. Para la enfermedad inflamatoria intestinal, la profilaxis extendida también tuvo costos más altos (+116 $; 95% IC, 109-123), más años de vida ajustados por calidad (+0.05; 95% IC, 0.04-0.06) y una relación costo-efectividad incremental de 2475 $/año de vida ajustado por calidad. La profilaxis prolongada evitó 16 (95% IC, 4-27) muertes relacionadas con tromboembolismo venoso por cada 100,000 pacientes y 22 (95% IC, 6-38) por malignidad y enfermedad inflamatoria intestinal, respectivamente. Hubo un 99.7% de probabilidad de costo-efectividad en un límite de disposición a pagar de 50,000 $/año de vida ajustado por calidad. Para tener en cuenta la incertidumbre estadística en torno a los variables, se realizó un análisis de sensibilidad y se encontró que la profilaxis extendida se asocia con menores costos generales cuando la incidencia de eventos tromboembólicos venosos después del alta hospitalaria alcanza 1.8%.Las diferencias significativas en los sistemas de salud pueden afectar la generalización de nuestros resultados.A pesar de la escasez de eventos tromboembólicos venosos, la tromboprofilaxis extendida es una estrategia rentable.

Abstract
PURPOSE To provide updated recommendations about prophylaxis and treatment of venous thromboembolism (VTE) in patients with cancer. METHODS PubMed and the Cochrane Library were searched for randomized controlled trials (RCTs) and meta-analyses of RCTs published from August 1, 2014, through December 4, 2018. ASCO convened an Expert Panel to review the evidence and revise previous recommendations as needed. RESULTS The systematic review included 35 publications on VTE prophylaxis and treatment and 18 publications on VTE risk assessment. Two RCTs of direct oral anticoagulants (DOACs) for the treatment of VTE in patients with cancer reported that edoxaban and rivaroxaban are effective but are linked with a higher risk of bleeding compared with low-molecular-weight heparin (LMWH) in patients with GI and potentially genitourinary cancers. Two additional RCTs reported on DOACs for thromboprophylaxis in ambulatory patients with cancer at increased risk of VTE. RECOMMENDATIONS Changes to previous recommendations: Clinicians may offer thromboprophylaxis with apixaban, rivaroxaban, or LMWH to selected high-risk outpatients with cancer; rivaroxaban and edoxaban have been added as options for VTE treatment; patients with brain metastases are now addressed in the VTE treatment section; and the recommendation regarding long-term postoperative LMWH has been expanded. Re-affirmed recommendations: Most hospitalized patients with cancer and an acute medical condition require thromboprophylaxis throughout hospitalization. Thromboprophylaxis is not routinely recommended for all outpatients with cancer. Patients undergoing major cancer surgery should receive prophylaxis starting before surgery and continuing for at least 7 to 10 days. Patients with cancer should be periodically assessed for VTE risk, and oncology professionals should provide patient education about the signs and symptoms of VTE.Additional information is available at www.asco.org/supportive-care-guidelines.

Abstract
The EuroG20 meeting on cancer-associated thrombosis (CAT) convened in Bergamo, Italy on 7 April 2016 to discuss a selection of controversial topics in CAT management. This satellite meeting besides ICTHIC in Bergamo has the objective to propose an European Guidance on CAT in various complex situations where evidence-based guidelines are lacking, driven by eminence-based thoughts of 20 experts and key opinion leaders in thrombosis from EU area and 8 experts from the rest of the world.

Abstract
Patients with primary or metastatic brain tumors are at increased risk of developing venous thromboses. However, the potential benefit of therapeutic anticoagulation in these patients must be weighed against the deadly complication of intracranial hemorrhage. In this review, we summarize available evidence and recent studies of intracranial bleeding risks in primary and metastatic tumors and the impact of therapeutic anticoagulation. We find that for the majority of primary and treated metastatic brain tumors, the risk of spontaneous bleeding is acceptable and not further increased by careful therapeutic anticoagulation with low molecular weight heparin or direct oral anticoagulants, although thrombocytopenia (platelet count less than 50,000/μL) and other coagulopathies are relative contraindications. Patients with brain metastasis from melanoma, renal cell carcinoma, choriocarcinoma, thyroid carcinoma, and hepatocellular carcinoma have a higher tendency to bleed spontaneously than noted in patients with other malignancies, and thus warrant routine brain imaging and alternative strategies such as inferior vena cava filter placement in the acute setting of venous thromboembolism before consideration of therapeutic anticoagulation. IMPLICATIONS FOR PRACTICE Malignant gliomas are associated with increased risks of both venous thromboses and intracranial hemorrhage, but the additional bleeding risk associated with therapeutic anticoagulation appears acceptable, especially after treatment of primary tumors. Most patients with treated brain metastasis have a low risk of intracranial hemorrhage associated with therapeutic anticoagulation, and low molecular weight heparin is currently the preferred agent of choice. Patients with untreated brain metastasis from melanoma, renal cell carcinoma, thyroid cancer, choriocarcinoma, and hepatocellular carcinoma have a higher propensity for spontaneous intracranial bleeding, and systemic anticoagulation may be contraindicated in the acute setting of venous thromboembolism.
