The Relationship

The relationship between venous thromboembolism and cancer has been known for many years, and there is solid scientific evidence addressing the adequate treatment of this condition in oncology patients. However, established prescribing habits, individual patient challenges, and uncertainty concerning treatment justifies poor adherence to published guidelines. This paper reviews venous thromboembolism treatment while focusing on vitamin K antagonists, low-molecular-weight heparins, and novel oral anticoagulants, namely in terms of their efficacy and limitations.

Direct Acting Oral Anticoagulants

Introduction Low molecular weight heparin is currently the standard therapy for the primary prevention of thromboembolic disease in cancer patients. The use of direct-acting anticoagulants could be an alternative, but its efficacy and safety profile in these types of patients remains unclear. Methods We searched in Epistemonikos, the largest database of systematic reviews in health, which is maintained by screening multiple sources of information, including MEDLINE, EMBASE, Cochrane, among others. We extracted data from identified reviews, analyzed data from primary studies, performed a meta-analysis, and prepared a summary table of results using the GRADE method. Results and conclusions We identified four systematic reviews that together included two primary studies, of which both correspond to trials. We conclude that the use of direct-acting oral anticoagulants probably increases the outcome of major bleeding and likely slightly increases the risk of thromboembolic disease. No studies were found that evaluated the outcome of quality of life or mortality.

To perform a systematic review and network meta-analysis evaluating the efficacy and safety of low-molecular-weight heparins (LMWHs), vitamin K antagonists (VKAs), and direct-acting oral anticoagulants (DOACs) for the treatment of cancer-associated thrombosis (CAT). We searched MEDLINE, Cochrane Central Register of Controlled Trials, and conference abstracts through March 2018. Randomized controlled trials (RCTs) enrolling adults with CAT comparing 2 or more full-dose anticoagulants (LMWH, VKA, and DOAC) and evaluating recurrent venous thromboembolism (VTE), major bleeding, and/or all-cause mortality were included. Reviewers identified studies, extracted data, and assessed the quality of the evidence in duplicate. A frequentist network meta-analysis, which uses direct and indirect evidence to simultaneously compare multiple interventions, was performed using a random-effects approach. Results are reported as pooled relative risks (RRs) with 95% confidence intervals (CIs). We included 13 RCTs (n = 6292): 7 compared LMWHs with VKAs, 4 compared DOACs with VKAs, and 2 compared DOACs with LMWHs. The risk of recurrent VTE was significantly reduced by 28% and 54% with a DOAC compared to an LMWH and a VKA, respectively. Low-molecular-weight heparins significantly reduced the risk of recurrent VTE by 36% versus VKAs. The risk of major bleeding was 14% higher with DOACs compared to LMWHs and 15% and 25% lower with DOACs and LMWHs versus VKAs, although 95% CIs included unity for each. The risk of all-cause mortality appeared similar for all 3 comparisons (RR = 1.0 for each comparison). Direct-acting oral anticoagulants appeared superior in reducing recurrent VTE in patients with CAT compared to LMWH and VKAs, but an increased risk of major bleeding versus LMWH cannot be ruled out.

The Cost

Abstract Background: Recently, new oral anticoagulants (NOACs) have been included in guidelines for the treatment of cancer-associated thrombosis (CAT) to be extended to suitable cancer patients. The purpose of this study was to compare the cost-effectiveness of using NOACs and low molecular weight heparins(LMWHs) for treating CAT from the perspective of the Chinese healthcare system. Methods: A Markov model was constructed to estimate the cost-effectiveness of the two strategies with a 6-month and 5-year time horizon. Input parameters were either sourced from the clinical trial, published literature. The primary outcome of the model was reported as incremental cost-effectiveness ratios (ICERs). Sensitivity analyses were performed to test model uncertainty. Results: The 6-month cost of NOACs was $ 654.65 with 0.40 QALYs while the 6-month cost of LMWHs was $ 1719.31 with 0.37 QALYs. Similarly, treatment with NOACs had a lower cost ($ 657.85 vs. $ 1716.56) and more health benefits (0.40 QALY vs. 0.37 QALY) than treatment with LMWHs in a subgroup of patients with gastrointestinal malignancy. We found treatment with NOACs would result in a large reduction in cost($ 1447.22 vs. $ 3374.70) but a small reduction in QALYs (3.07 QALY vs. 3.09 QALY) compared with LMWHs over a 5-year time frame, resulting in an ICER of $ 112895.50/QALY. Sensitivity analysis confirmed the robustness of the results. Conclusion: As compared to LMWHs, NOACs can be a cost-saving anticoagulant choice for the treatment of CAT in the general oncology population and gastrointestinal malignancy population.Classification codes: I.

Purpose: Current guidelines favor 4F-PCC over plasma for reversal of warfarin. Uncertainty remains on the hemostatic effectiveness and thrombotic risk of 4F-PCC for direct-acting oral anticoagulants (DOACs), particularly in patients with intracranial hemorrhage (ICH). This study sought to evaluate the effectiveness and safety of a lower dose protocol of 25 units/kg 4F-PCC for the management of DOAC-associated ICH in a real-world setting. Materials and Methods: This was a retrospective study of adult patients who received at least one dose of 4F-PCC from March 2014 to December 2015 for DOAC-associated ICH. The primary outcome was hemostatic effectiveness within 24 hours. The secondary outcome was thromboembolic events within 14 days. Results: Twenty-two patients received 4F-PCC for DOAC-associated ICH and were included in the analysis. Hemostasis was evaluable in 19 patients with post-4F-PCC imaging available and occurred in 18/19 (94.7%) patients. Thromboembolism occurred in 2 out of 22 patients (9.1%). Conclusions: The use of a lower dose protocol of 25 units/kg of 4F-PCC resulted in high rates of hemostasis in patients with DOAC-associated ICH. Two patients developed thrombotic events within 14 days of 4F-PCC administration.

Direct Acting Oral Anticoagulants

Background Direct‐acting oral anticoagulants are now the preferred method of anticoagulation in patients with atrial fibrillation. Limited data on efficacy and safety of these fixed‐dose regimens are available in severe obesity where drug pharmacokinetics and pharmacodynamics may be altered. The objectives of this study were to evaluate efficacy and safety in patients with atrial fibrillation taking direct‐acting oral anticoagulants across body mass index (BMI) categories in a contemporary, real‐world population. Methods and Results We performed a retrospective study of patients with atrial fibrillation at an integrated multisite healthcare system. Patients receiving a direct‐acting oral anticoagulant prescription and ≥12 months of follow‐up between 2010 and 2017 were included. The primary efficacy and safety outcomes were ischemic stroke or systemic embolism and intracranial hemorrhage. We performed Cox proportional hazards modeling to compute hazard ratios (HRs) adjusted for CHA 2 DS 2 ‐VASc score to examine differences by excess BMI categories relative to normal BMI. Of 7642 patients, mean±SD age was 69±12 years with a median (interquartile range) follow‐up of 3.8 (2.2–6.0) years. Approximately 22% had class 1 obesity and 19% had class 2 or 3 obesity. Stroke risks were similar in patients with and without obesity (HR, 1.2; 95% CI, 0.5–2.9; and HR, 0.68; 95% CI, 0.23–2.0 for class 1 and class 2 or 3 obesity compared with normal BMI, respectively). Risk of intracranial hemorrhage was also similar in class 1 and class 2 or 3 obesity compared with normal BMI (HR, 0.64; 95% CI, 0.35–1.2; and HR, 0.66; 95% CI, 0.35–1.2, respectively). Conclusions Direct‐acting oral anticoagulants demonstrated similar efficacy and safety across all BMI categories, even at high weight values.

Bleeding Events

Purpose Low-molecular-weight heparins are currently the recommended antithrombotic therapy for treatment and prevention of malignancy-related venous thromboembolism. Currently, the evidence evaluating direct oral anticoagulants versus low-molecular-weight heparins or a vitamin K antagonist in cancer patients with hematologic malignancies is limited. We evaluated the safety and efficacy of direct oral anticoagulants for venous thromboembolism treatment or stroke prevention for non-valvular atrial fibrillation in patients with hematologic malignancies. Methods This was a retrospective evaluation of adult patients with hematologic malignancies who received at least one dose of the Food and Drug Administration-approved direct oral anticoagulant for venous thromboembolism treatment or stroke prevention. We determined the frequency of major bleeding events, non-major bleeding events, stroke, systemic embolism, appropriateness of initial direct oral anticoagulant doses, holding practices prior to procedures, and the rate of all-cause mortality. An analysis was also performed to compare the incidence of bleeding between patients with a history of hematopoietic stem cell transplant to non-transplant patients. Results A total of 103 patients were identified, with the majority of patients receiving rivaroxaban for venous thromboembolism treatment. Major bleeding events occurred in four patients and no fatal bleeding events occurred. Non-major bleeding occurred in 29 patients, most commonly epistaxis and bruising. Two patients experienced a systemic embolism while on direct oral anticoagulant therapy. Conclusion Direct oral anticoagulants may be a safe and effective alternative for anticoagulation therapy in patients with hematologic malignancies. However, larger prospective studies comparing direct oral anticoagulants to low-molecular-weight heparins or vitamin K antagonists are warranted to compare efficacy and safety outcomes in this patient population.
