Meta Analyses

Objective: To review evidence behind anticoagulants in cancer-associated venous thromboembolism (VTE) with a focus on low-molecular-weight heparins (LMWH) and the role of direct oral anticoagulants (DOACs). Data Sources: PubMed was searched using terms “venous thromboembolism,” “cancer,” and “anticoagulation.” This search was restricted to clinical trials, meta-analyses, and subgroup analyses. Additional references were identified from reviewing literature citations. Study Selection: English-language prospective and retrospective studies assessing the efficacy and safety of LMWH and DOACs in patients with cancer. Data Analysis: Several trials were analyzed that compared anticoagulation therapies for prevention of recurrent VTE in patients with cancer. Many studies comparing LMWH and vitamin K antagonists (VKAs) found nonsignificant differences between therapies. A single study demonstrated that LMWHs are superior to VKAs. This evidence supporting LMWH for long-term VTE treatment in patients with cancer is based on comparison to VKA, but results are limited by methodological issues, and the benefit of LMWH may be driven by poor control. Subanalyses of DOAC trials suggest these are equally or more effective as VKA in cancer, but this conclusion is underpowered. Conclusion: DOACs have the potential to bypass many challenges with traditional therapy. After analyzing the evidence available, we conclude that after careful consideration of risks and benefits, use of DOACs for VTE treatment are a reasonable option in patients with cancer.

e23156 Background: A direct meta-analysis was performed to explore the efficacy and safety of direct oral factor Xa inhibitors with dalteparin in patients with cancer associated acute venous thromboembolism (VTE). Also, the comparative efficacy and safety of apixaban, rivaroxaban, and edoxaban was assessed with a network meta-analysis. Methods: MEDLINE, CENTRAL, and EMBASE were searched for trials comparing direct oral anticoagulants (DOACs) to dalteparin for the management of cancer associated acute VTE. A network meta-analysis using both frequentist and Bayesian methods was performed to analyze VTE recurrence, major and clinically relevant non-major bleeding (CRNMB). Results: Three randomized control trials, at low risk of bias, enrolled 1,739 patients with cancer associated VTE. Direct comparison showed a lower rate of VTE recurrence in DOAC compared to dalteparin groups (odds Ratio [OR]:0.48, 95% Confidence interval [CI]:0.24-0.96; I2:46%). Indirect comparison suggested that apixaban had greater reduction in VTE recurrence compared to dalteparin (OR: 0.10; 95% CI: 0.01–0.82), but not rivaroxaban or edoxaban. Apixaban also had the highest probability of being ranked most effective. By direct comparisons, there was an increased likelihood of major bleeding in the DOAC group compared to dalteparin (OR: 1.70; 95% CI: 1.04–2.78). CRNMB did not differ. Indirect estimates were imprecise. Subgroup analyses in gastrointestinal cancers suggested that dalteparin may have the lowest risk of bleeding whereas estimates in urothelial cancer were imprecise. Conclusions: DOACs appear to lower the risk of VTE recurrence compared to daltaparin while increasing major bleeding. Apixaban may be associated with the lowest risk of VTE recurrence compared to the other DOACs.

Increased Risk

Patients with cancer are at increased risk of venous thromboembolism (vte). Anticoagulation therapy is used to treat vte; however, patients with cancer have unique clinical circumstances that can often make decisions surrounding the administration of therapeutic anticoagulation complicated. No national Canadian guidelines on the management of established cancer-associated thrombosis have been published. We therefore aimed to develop a consensus-based, evidence-informed guideline on the topic.PubMed was searched for clinical trials and meta-analyses published between 2002 and 2013. Reference lists of key articles were hand-searched for additional publications. Content experts from across Canada were assembled to review the evidence and make recommendations.Low molecular weight heparin is the treatment of choice for cancer patients with established vte. Direct oral anticoagulants are not recommended for the treatment of vte at this time. Specific clinical scenarios, including the presence of an indwelling venous catheter, renal insufficiency, and thrombocytopenia, warrant modifications in the therapeutic administration of anticoagulation therapy. Patients with recurrent vte should receive extended (>3 months) anticoagulant therapy. Incidental vte should generally be treated in the same manner as symptomatic vte. There is no evidence to support the monitoring of anti–factor Xa levels in clinically stable cancer patients receiving prophylactic anticoagulation; however, levels of anti–factor Xa could be checked at baseline and periodically thereafter in patients with renal insufficiency. Follow-up and education about the signs and symptoms of vte are important components of ongoing patient care.

The Impact

Abstract Venous thromboembolism (VTE) is a major therapeutic concern in cancer patients and the leading cause of death after metastasis. Providing anticoagulant therapy to this patient population is challenging because cancer patients are at increased risk of VTE recurrence and bleeding, and treatment management is often complicated by other co-morbidities that affect choice of anticoagulation. The International Initiative on Thrombosis and Cancer (ITAC-CME) is a multidisciplinary group of International academic clinicians, researchers, and experts dedicated to reducing the global burden of VTE and its consequences in cancer patients. In 2013, the group published international clinical practice guidelines for the treatment and prophylaxis of VTE in cancer (1, 2). In collaboration with CME solutions, an accredited CME provider, ITAC-CME developed a mobile web-based application to promote the international implementation of the 2013 guidelines, in English and French (www.itacc-cme.org). Usage of the app has steadily increased every year since its release. ITAC-CME recently revised its consensus recommendations according to a systematic review of the literature up to January 2016. In particular, the ISTH-endorsed updated recommendations provide a guidance on the use of the direct oral anticoagulants based on the current level of evidence (3). ITAC-CME and CME solutions have updated the web-based application to support the 2016 guidelines. The app also includes several new features, including interactive case-based CME learning activities, with pre- and post-activity practice assessments. These pre- and post-test metrics will be documented to record international clinical practice patterns, and monitor the impact of the app on the adoption of the 2016 guidelines into clinical practice worldwide. Translation of the 2016 updated app into additional languages is planned. The application has been submitted for accreditation with the royal College of Physicians and surgeons of Canada, the American Medical Association, the European Union of Medical Specialists, l' Organisme Gestionnaire du Développement Professionnel Continu, and the European Board for Accreditation in Hematology. 1 Debourdeau P, Farge D, Beckers M, Baglin C, Bauersachs RM, Brenner B, Brilhante D, Falanga A, Gerotzafias GT, Haim N, Kakkar AK, Khorana AA, Lecumberri R, Mandala M, Marty M, Monreal M, Mousa SA, Noble S, Pabinger I, Prandoni P, Prins MH, Qari MH, Streiff MB, Syrigos K, Büller HR, Bounameaux H.

Dose Reductions

AbstractAs a result of the successful completion of their respective phase III studies compared with vitamin K antagonists (VKAs), four direct oral anticoagulants (DOACs) have been approved for the treatment and secondary prevention of venous thromboembolism (VTE). These DOACs—apixaban, dabigatran, edoxaban, and rivaroxaban—have subsequently seen a steady uptake among clinicians since their approval. Despite the suitability of DOACs for a broad range of patients, they are not appropriate in certain situations, whereas in others they require additional considerations such as dose reductions. Subanalyses of phase III trials and studies on specific VTE patient populations have been conducted to evaluate the safety and efficacy of the DOACs in a broad range of settings, such as patients with renal impairment, patients with cancer, patients of childbearing potential, patients with multiple comorbidities and pediatric patients. Furthermore, many recent guidance documents from important hematological societies and other specialists have incorporated several of these developments. These documents also identify the patients for whom DOACs are not suitable and where traditional anticoagulation options such as heparins or VKAs should be considered instead. This review provides an overview of key VTE patient subgroups, the clinical evidence supporting the use of anticoagulation in these patients, and a discussion of the most appropriate approaches to their management, including considerations such as dosing, acute and extended treatment durations, and DOAC selection.

AbstractPatients with cancer are prone to develop venous thromboembolism (VTE) that is the second leading cause of mortality among them. Cancer patients with VTE may encounter higher rates of VTE recurrence and bleeding complications than patients without cancer. Treatment of established VTE is often complex in patients with cancer. Treatment of cancer-associated VTE basically comprises initial treatment, long-term treatment, treatment within 6 months, treatment beyond 6 months, treatment of recurrent VTE, and treatment in special situations. Decision of antithrombotic therapy, selection of anticoagulants, duration of anticoagulation, decision of adjuvant therapy, and adjustment of regimen in special situations are the major problems in the treatment of cancer-associated VTE. Therapeutic anticoagulation is the key of the key in the treatment of cancer-associated VTE. In addition to the efficacy and safety of low-molecular-weight heparin (LMWH) that has been fully demonstrated, direct oral anticoagulants (DOACs) are increasingly showing its advantages along with the accompanying concern in the treatment of cancer-associated VTE. The latest ASCO, ITAC and NCCN guidelines agree with each other on most aspects with respect to the treatment of cancer-associated VTE, whereas differ on a few issues. Encompassing recent randomized controlled trials, clinical trials, and meta-analyses, as well as the comparison of the latest authoritative guidelines including the NCCN, ASCO, and ITAC guidelines in this field, the objective of this review is to present current overview and recommendations for the treatment of cancer-associated VTE.
