Non-Vitamin K Antagonist Oral Anticoagulants versus Low Molecular Weight Heparin for Cancer-Related Venous Thromboembolic Events: Individual Patient Data Meta-Analysis. Cancers (Basel) 2023; 15:5887. [PMID: 38136433 PMCID: PMC10741613 DOI: 10.3390/cancers15245887] [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: 11/06/2023] [Revised: 12/09/2023] [Accepted: 12/16/2023] [Indexed: 12/24/2023] Open
Abstract
Venous thromboembolism (VTE) is a leading cause of morbidity and mortality in cancer patients. Low molecular weight heparin (LMWH) has been the standard of care but new guidelines have approved the use of non-vitamin K antagonist oral anticoagulants (NOAC). By conducting an individual patient data (IPD) meta-analysis of randomised controlled trials (RCTs) comparing the outcomes of NOAC versus LMWH in cancer patients, we aim to determine an ideal strategy for the prophylaxis of VTE and prevention of VTE recurrence. Three databases were searched from inception until 19 October 2022. IPD was reconstructed from Kaplan-Meier curves. Shared frailty, stratified Cox and Royston-Parmar models were fit to compare the outcomes of venous thromboembolism recurrence and major bleeding. For studies without Kaplan-Meier curves, aggregate data meta-analysis was conducted using random-effects models. Eleven RCTs involving 4844 patients were included. Aggregate data meta-analysis showed that administering NOACs led to a significantly lower risk of recurrent VTE (RR = 0.65; 95%CI: 0.50-0.84) and deep vein thrombosis (DVT) (RR = 0.60; 95%CI: 0.40-0.90). In the IPD meta-analysis, NOAC when compared with LMWH has an HR of 0.65 (95%CI: 0.49-0.86) for VTE recurrence. Stratified Cox and Royston-Parmar models demonstrated similar results. In reducing risks of recurrent VTE and DVT among cancer patients, NOACs are superior to LMWHs without increased major bleeding.

Abstract
INTRODUCTION We compared the safety and efficacy of Xa-inhibitors to LMWH for treatment of venous thromboembolism in mixed and gastrointestinal cancer cohorts (CA-VTE). METHODS A systematic search identified RCTs and non-randomized studies (NRS) comparing Xa-inhibitors to LMWH for treating CA-VTE. Relative risks were computed. Certainty was assessed using the GRADE approach. RESULTS Xa-inhibitors reduced the risk of recurrent VTE (RR0.64;0.49-0.84) and NRS (RR0.74;0.60-0.92;Moderate-Low Certainty). There was no significant difference in recurrent PE in RCTs (RR0.72;0.50-1.02) and NRS (1.43;0.65-3.12;Low-Very Low Certainty). Xa-inhibitors increased the risk of overall bleeding events in RCTs (RR1.45;1.05-2.01) and NRS (RR1.72;1.42-2.08;Moderate-Low Certainty), and the risk of major bleeding events in NRS (RR1.56;1.17-2.07), but not in RCTs (RR1.33;0.94-1.89; Low-Very Low Certainty). Similar results were detected in gastrointestinal cancer patients. CONCLUSION Xa-inhibitors may reduce the risk of recurrent VTE, but not recurrent PE compared to LMWH. A higher overall bleeding risk, and a questionably higher major bleeding risk was found with Xa-inhibitor use.

Abstract
BACKGROUND Venous thromboembolism (VTE) is a common complication among patients with cancer. Patients with cancer and VTE are at a markedly increased risk for morbidity and mortality. OBJECTIVE These evidence-based guidelines of the American Society of Hematology (ASH) are intended to support patients, clinicians, and other health care professionals in their decisions about the prevention and treatment of VTE in patients with cancer. METHODS ASH formed a multidisciplinary guideline panel balanced to minimize potential bias from conflicts of interest. The guideline development process was supported by updated or new systematic evidence reviews. The Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach was used to assess evidence and make recommendations. RESULTS Recommendations address mechanical and pharmacological prophylaxis in hospitalized medical patients with cancer, those undergoing a surgical procedure, and ambulatory patients receiving cancer chemotherapy. The recommendations also address the use of anticoagulation for the initial, short-term, and long-term treatment of VTE in patients with cancer. CONCLUSIONS Strong recommendations include not using thromboprophylaxis in ambulatory patients receiving cancer chemotherapy at low risk of VTE and to use low-molecular-weight heparin (LMWH) for initial treatment of VTE in patients with cancer. Conditional recommendations include using thromboprophylaxis in hospitalized medical patients with cancer, LMWH or fondaparinux for surgical patients with cancer, LMWH or direct oral anticoagulants (DOAC) in ambulatory patients with cancer receiving systemic therapy at high risk of VTE and LMWH or DOAC for initial treatment of VTE, DOAC for the short-term treatment of VTE, and LMWH or DOAC for the long-term treatment of VTE in patients with cancer.

Abstract
Direct oral anticoagulants (DOACs) may be good alternatives to low molecular weight heparin (LMWH) or vitamin K antagonists (VKA) for treatment of cancer associated thrombosis (CAT). We conducted a meta-analysis of ten randomized clinical trials to evaluate the efficacy and safety of DOACs in patients with CAT. All had study populations composed in entirety or in part of patients with CAT. The primary outcome (efficacy) was recurrent VTE and the secondary outcomes (safety outcomes) included major bleeding, clinically relevant non-major bleeding (CRNMB), and all bleeding (major bleeding + CRNMB). Participants treated with DOACs had lower risk of recurrent VTE, overall (RR 0.63; 95% CI 0.51-0.79; p < 0.0001), compared to LMWH (RR 0.57; 95% CI 0.40-0.83; p = 0.003), but not compared to VKA (RR 0.69; 95% CI 0.44-1.06; p = 0.09). Compared to LMWH, DOACs showed no difference in major bleeding risk (RR 1.31; 95% CI 0.78-2.18; p = 0.31), though had higher risk of CRNMB (RR 1.60; 95% CI 1.13-2.26; p = 0.008) and all bleeding (RR 1.49; 95% CI 1.10-2.01; p = 0.010). These results indicate that DOACs are more effective than LMWH for prevention of recurrent VTE with CAT though carry an increased risk for non-major bleeding compared to standard of care, LMWH.

Abstract
Novel Oral Anticoagulants (NOACs) have been considered for treating cancer-related venous thromboembolism (VTE), but safety issues have been raised. We performed a systematic review and pairwise meta-analysis of the efficacy and safety of NOACs versus low molecular weight heparin (LMWH) in this setting. Four randomized controlled trials were included, providing data on 2894 patients. Compared to LMWH, NOACs were associated with a significantly lower risk of VTE recurrence and were not associated with an increased risk of major bleedings (MB). NOACs were non inferior to LMWH for a composite outcome of VTE recurrence and MB, pulmonary embolism recurrence and all-cause mortality; however, NOACs were associated with an increased risk of clinically relevant nonmajor bleedings (CRNMB) and gastrointestinal MB. In conclusion, in patients with cancer-related VTE, NOACs are effective and safe in reducing VTE recurrence compared to LMWH. An increased risk of CNRMB and GI MB should nonetheless be considered.

Abstract
Background: Venous thromboembolism (VTE) is a common complication in cancer patients. We aim to evaluate the effect and safety of direct oral anticoagulants (DOACs) as primary prophylaxis in ambulatory cancer patients.Methods: We conducted a literature search in PubMed, EMBASE and ClinicalTrials for studies that evaluated DOACs for thromboprophylaxis in cancer patients. RevMan 5.3 software was used for this meta-analysis.Results: Three randomized controlled trials (RCTs) with a total of 1465 patients were pooled in the meta-analysis. DOACs significantly reduced the symptomatic VTE incidence during intervention period (RR 0.23, CI 0.11-0.47, P<0.0001, I2=9%). Significantly lower total VTE incidence (RR 0.53, CI 0.36-0.78, P = 0.001, I2 =30%) and PE incidence (RR 0.50, CI 0.28-0.89, P = 0.02, I2 =5%) were found during the observation period, and a trend for less symptomatic DVT events was found in the DOACs group (RR 0.62, CI 0.37-1.04, P = 0.07, I2 =5%). No differences for all-cause mortality were found between groups (RR 0.92, CI 0.74-1.15, P = 0.47, I2 =14%). DOACs did not significantly increase major bleeding risks (RR 1.66, CI 0.72-3.83, P = 0.24, I2 =0%) during the intervention period or clinically relevant non-major bleeding events (RR 1.50, CI 0.90-2.49, P = 0.12, I2 =0%) and total bleeding events during the observation period (RR 1.50, CI 0.98-2.29, P = 0.06, I2 =0%).Conclusion: DOACs are effective for thromboprophylaxis in ambulatory cancer patients, but there is a potential risk of bleeding. DOACs may be recommended in selected patients at high risk of VTE. More high-quality studies are needed to further validate our results.Abbreviations: CAT: cancer-associated thrombosis; CI: confidence interval; DOAC: direct oral anticoagulant; DVT: deep vein thrombosis; LMWH: low molecular weight heparin; NNH: number needed to harm; NNT: number needed to treat; PE: pulmonary embolism; RCT: randomized controlled trials; RR: risk ratio; RD: rate difference; VTE: venous thromboembolism.

Abstract
The efficacy and safety of direct oral anticoagulants (DOACs) versus low-molecular-weight heparin (LMWH) are still debated in the treatment of patients with cancer, and the optimal duration of therapy remains uncertain. Electronic databases (PubMed, Embase, and Cochrane Library) were searched to retrieve studies on the efficacy and safety of DOACs versus LMWH in treating patients with cancer from January 1980 to October 2018. The primary efficacy and safety endpoints were recurrent venous thromboembolism (VTE) and major bleeding. Our study included two randomized controlled trials (RCTs) and nine observational studies, together comprising 4509 patients with cancer. The pooled estimates indicated that DOACs led to a modest reduction recurrent VTE in the RCTs [RR: 0.63, 95% confidence interval (CI), 0.42-0.96, P = 0.03] and in the observational studies (RR: 0.74, 95% CI, 0.58-0.93, P = 0.011), without increasing the risk of major bleeding for observational studies (P = 0.805), but increased for RCTs (P = 0.017). The same trends were observed in the rivaroxaban subgroup. Moreover, subgroup analyses according to the treatment duration indicated that DOACs significantly reduced the incidence of recurrent VTE (P = 0.006 at 6 months; P < 0.001 at 12 months) without significant differences in major bleeding compared with LMWH at 6 or 12 months. Patients with cancer who received DOACs exhibited a significant reduction in recurrent VTE with no increased risk of major bleeding compared with LMWH. DOACs may be an alternative choice for long-term anticoagulant therapy in patients with cancer.

Direct versus conventional anticoagulants for treatment of cancer associated thrombosis: a pooled and interaction analysis between observational studies and randomized clinical trials. ANNALS OF TRANSLATIONAL MEDICINE 2020; 8:95. [PMID: 32175388 PMCID: PMC7049023 DOI: 10.21037/atm.2019.12.152] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/30/2019] [Accepted: 11/21/2019] [Indexed: 01/01/2023]
Abstract
BACKGROUND There are emerging observational studies (OSs) to assess real-world comparative effectiveness and safety of direct oral anticoagulants (DOACs) in cancer associated thrombosis (CAT). We conducted a pooled and interaction analysis to compare the treatment effect estimates of DOACs between OSs and randomized controlled trials (RCTs). METHODS We systematically searched PUBMED, EMBASE and Cochrane Library for OSs and RCTs that reported recurrent venous thromboembolism (VTE) and/or major bleeding events in CAT patients receiving DOACs and conventional anticoagulants [warfarin or low molecular-weight heparins (LMWHs)]. Relative risks (RRs) for OSs and RCTs were calculated using random-effects models separately, and interaction analyses were afterward applied to assess the comparability between OSs and RCTs. RESULTS Baseline characteristic was comparable between identified 10 OSs (35,142 patients) and 8 RCTs (2,602 patients). Overall, no significant difference of treatment effect estimates between OSs and RCTs was detected (Pinteraction: 0.42 for recurrent VTE; Pinteraction: 0.38 for major bleeding). DOACs significantly decreased the risk of recurrent VTE compared with conventional anticoagulants in CAT patients (RR: 0.74, 95% CI: 0.63-0.86, I2: 0% for OSs; RR: 0.65, 95% CI: 0.49-0.86; I2: 0% for RCTs), without increasing major bleeding risk (RR: 0.90, 95% CI: 0.76-1.07, I2: 24.0% for OSs; RR: 1.17, 95% CI: 0.72-1.88, I2: 26.2% for RCTs). Whereas, increased risk of gastrointestinal bleeding (GIB) was found with DOACs versus conventional anticoagulants in CAT patients (RR: 2.77, 95% CI: 1.35-5.68, I2: 0% for RCTs). Analyses of subgroups, based on comparators and follow-up duration, did not significantly affect results. CONCLUSIONS In this study, effectiveness and safety of DOACs versus conventional anticoagulants in CAT from OSs are in agreement with those from RCTs, confirming a low risk of recurrent VTE and similar risk of major bleeding in CAT patients receiving DOACs.

Abstract
Efficacy and safety of direct oral anticoagulants (DOACs) for preventing primary and recurrent venous thromboembolism (VTE) in patients with cancer remain unclear. In this study, we conducted a systematic review to summarize the most up-to-date evidence from randomized controlled trials (RCTs). Our primary outcomes included the benefit outcome (VTE) and safety outcome (major bleeding). A random-effects model was used to pool the relative risks (RRs) for data syntheses. The Grading of Recommendations Assessment, Development and Evaluation tool was used to evaluate the quality of the entire body of evidence across studies. We included 11 RCTs with a total of 3741 patients with cancer for analyses. The DOACs were significantly related with a reduced risk of VTE when compared with non-DOACs: RR = 0.77, 95% confidence interval [CI]: 0.61-0.99, P = .04. Nonsignificant trend towards a higher risk of major bleeding was found in DOACs: RR = 1.28 95% CI: 0.81-2.02, P = .29. The quality of the entire body of evidence was graded as moderate for risk of VTE, and low for risk of major bleeding. To summarize, DOACs were found to have a favorable effect on risk of VTE but a nonsignificant higher risk of major bleeding compared with non-DOACs in patients with cancer. The safety effect of DOACs in patients with cancer requires further evaluation in adequately powered and designed studies.

Abstract
Cancer patients develop a hypercoagulable state with a four- to seven-fold higher thromboembolic risk compared to non-cancer patients. Thromboembolic events can precede the diagnosis of cancer, but they more often occur at diagnosis or during treatment. After malignancy itself, they represent the second cause of death. Low molecular weight heparins are the backbone of the treatment of cancer-associated thromboembolism. This treatment paradigm is possibly changing, as direct oral anticoagulants (DOACs) may prove to be an alternative therapeutic option. The currently available DOACs were approved during the first and second decades of the 21st century for various clinical indications. Three molecules (apixaban, edoxaban and rivaroxaban) are targeting the activated factor X and one (dabigatran) is directed against the activated factor II, thrombin. The major trials analyzed the effect of these agents in the general population, with only a small proportion of cancer patients. Two published and several ongoing studies are specifically investigating the use of DOACs in cancer-associated thromboembolism. This article will review the current available literature on the use of DOACs in cancer patients. Furthermore, we will discuss published data suggesting potential anti-cancer actions exerted by non-anticoagulant effects of DOACs. As soon as more prospective data becomes available, DOACs are likely to be considered as a potential new therapeutic option in the armamentarium for patients suffering of cancer-associated thromboembolism.
