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.

Abstract Background Direct oral anticoagulants (DOACs) are recommended as first-line anticoagulants in patients with atrial fibrillation (AF). However, in patients with cancer and AF the efficacy and safety of DOACs are not well established. Objective We performed a meta-analysis comparing available data regarding the efficacy and safety of DOACs vs vitamin K antagonists (VKAs) in cancer patients with non-valvular AF. Methods An online search of Pubmed and EMBASE libraries (from inception to May, 1 2020) was performed, in addition to manual screening. Nine studies were considered eligible for the meta-analysis involving 46,424 DOACs users and 182,797 VKA users. Results The use of DOACs was associated with reduced risks of systemic embolism or any stroke (RR 0.65; 95% CI 0.52–0.81; p 0.001), ischemic stroke (RR 0.84; 95% CI 0.74–0.95; p 0.007) and hemorrhagic stroke (RR 0.61; 95% CI 0.52–0.71; p 0.00001) as compared to VKA group. DOAC use was associated with significantly reduced risks of major bleeding (RR 0.68; 95% CI 0.50–0.92; p 0.01) and intracranial or gastrointestinal bleeding (RR 0.64; 95% CI 0.47–0.88; p 0.006). Compared to VKA, DOACs provided a non-statistically significant risk reduction of the outcomes major bleeding or non-major clinically relevant bleeding (RR 0.94; 95% CI 0.78–1.13; p 0.50) and any bleeding (RR 0.91; 95% CI 0.78–1.06; p 0.24). Conclusions In comparison to VKA, DOACs were associated with a significant reduction of the rates of thromboembolic events and major bleeding complications in patients with AF and cancer. Further studies are needed to confirm our results.

Background The efficacy and safety of the direct oral anticoagulants (DOACs) in fragile patients (age ≥ 75 years and/or creatinine clearance levels ≤ 50 mL/min and/or body weight ≤ 50kg) with venous thromboembolism (VTE) has not been evaluated. Methods We used the RIETE database to compare the rates of the composite of VTE recurrences or major bleeding during anticoagulation in fragile patients with VTE, according to the use of DOACs or standard anticoagulant therapy. Results From January 2013 to April 2018, 24,701 patients were recruited. Of these, 10,054 (41%) were fragile. Initially, 473 fragile patients (4.7%) received DOACs and 8,577 (85%) low-molecular-weight heparin (LMWH). For long-term therapy, 1,298 patients (13%) received DOACs and 5,038 (50%) vitamin K antagonists (VKAs). Overall, 95 patients developed VTE recurrences and 262 had major bleeding. Patients initially receiving DOACs had a lower rate of the composite outcome (hazard ratio [HR]: 0.32; 95% confidence interval [CI]: 0.08–0.88) than those on LMWH. Patients receiving DOACs for long-term therapy had a nonsignificantly lower rate of the composite outcome (HR: 0.70; 95% CI: 0.46–1.03) than those on VKAs. On multivariable analysis, patients initially receiving DOACs had a nonsignificantly lower risk for the composite outcome (HR: 0.36; 95% CI: 0.11–1.15) than those on LMWH, while those receiving DOACs for long-term therapy had a significantly lower risk (HR: 0.61; 95% CI: 0.41–0.92) than those on VKAs. Conclusions Our data suggest that the use of DOACs may be more effective and safe than standard therapy in fragile patients with VTE, a subgroup of patients where the risk for bleeding is particularly high.

SummaryIn 20 patients suffering from bleeding complications during long-term treatment with phenprocoumon, the depression of the activity of Factors II, VII, IX and X, on the average, was found to be stronger than in so-called adequately treated patients, whereas no statistically significant differences could be demonstrated between the average activity of the 4 factors. The individual variations between the 4 factors were higher than those found in normal individuals and adequately treated patients.Thrombotest activity appeared to be considerably lower than the average factor activity. This discrepancy is mainly caused by the action of the recently discovered circulating anticoagulant occurring in coumarin-treated or vitamin K-deficient patients.

Abstract Introduction: The coagulopathy associated with cirrhosis is complex and places patients at risk for both bleeding and thrombosis. Direct oral anticoagulants (DOACs) have been shown to have superior efficacy and safety compared to vitamin K antagonists; however their efficacy and safety in cirrhotic patients is not clear. The aim of this study is to retrospectively compare the effectiveness and bleeding complications of DOACs as compared to traditional anticoagulants in cirrhotic patients. Methods: This study was a retrospective review of patients treated at a single academic center between 2012-2015 who were prescribed a DOAC (apixaban or rivaroxaban), or a traditional anticoagulant (warfarin or low molecular weight heparin), with an ICD-9 code for the diagnosis of cirrhosis. The primary outcomes of interest are recurrent thrombosis or stroke (efficacy failure), or bleeding events (safety failure). Major bleeds were characterized as fatal bleeding, symptomatic bleeding in critical organ area, or bleeding causing a fall in hemoglobin level >2 or leading to transfusion of 2+ units of packed red blood cells. Results: During the study period, 27 cirrhotic patients were prescribed a DOAC and 18 were prescribed a traditional anticoagulant (either LMWH or warfarin). Both groups had similar total bleeding events (8 DOAC vs. 10 traditional anticoagulation, p = 0.12). There were significantly less major bleeding episodes in the DOAC group, (1 (4%) vs. 5 (28%), p = 0.03) and less intracranial bleeding (3 (17% ) vs. 0 (0%) p=0.06). Recurrent thrombosis or stroke occurred in 1 (4%) patient in the DOAC group and 1 (6%) patient in the traditional group (p = 1.0). Conclusions: Anticoagulation with DOACs in cirrhotic patients may be as safe as traditional anticoagulants with respect to bleeding events. Patients with cirrhosis at our center prescribed DOACs had less major bleeding events, while maintaining efficacy at preventing stroke or recurrent thrombosis. Table Table.
