According to current guidelines, patients with venous thromboembolism (VTE) and active cancer should receive prolonged anticoagulant treatment (>6 months). In patients with cancer-associated thrombosis (CAT), metastasis is a factor in recurrent VTE and bleeding; however, the function of metastasis location remains unclear. In order to assess the risk of complications (such as bleeding or recurrent VTE) based on the location of metastases in patients with CAT, we conducted a systematic review. The PubMed database search was used to perform a systematic review. MESH terms pertaining to metastasis, VTE, and neoplasms were employed. Patients with CAT who were at least eighteen years old and receiving therapeutic doses of anticoagulants were included, as were details regarding the locations of metastases and the availability of patients who had complications (bleeding or recurrent VTE). Among the 1,447 articles found by the search, 7 retrospective studies met all eligibility requirements and were added to the analysis. The majority of these studies addressed brain metastases. Studies found that intracranial hemorrhage occurred between 4% and 19% of the time. In the context of brain metastases and VTE, other studies examined the safety and effectiveness of direct oral anticoagulants in comparison to low-molecular-weight heparin. This systematic review draws attention to the paucity of data regarding the impact of metastasis location on complications in CAT patients. Further research is required to assess the effect of metastasis location on the risk of VTE complications in patients with CAT.
