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
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.
