Background Low-molecular weight heparin (LMWH) was shown to be effective and safe in treating venous thromboembolism, and generally used for stroke in cancer patients, but its effects on stroke are unclear. We compared clinical outcomes between LMWH and new oral anticoagulant (NOAC) in patients with cancer-related stroke. Methods We enrolled patients with cryptogenic ischemic stroke with active cancer who were treated with LMWH or NOAC between May 2012 and June 2015. The clinical outcomes, including early neurologic deterioration, early radiologic recurrence, 3-month modified Rankin scale score, 90-day mortality, cardio-cerebrovascular recurrence, and bleeding complications, were compared. Results Among 48 patients, 7 patients were treated with NOAC, and the remaining 41 patients with LMWH. Overall, the participants presented poor outcomes, including 20 (42%) early neurologic deteriorations, 28 (58%) early radiologic recurrences, 34 (71%) poor modified Rankin scale scores, 27 (56%) 90-day mortality events, 24 (50%) cardio-cerebrovascular recurrences, and 18 (38%) bleeding complications, that led to a change or temporary hold in medication in 12 cases. No statistical differences were found between the 2 groups in terms of demographic, clinical, or cardiovascular risk factors and clinical outcomes. Conclusions NOAC showed the similar clinical outcomes and safety compared with LMWH in the treatment of cryptogenic ischemic stroke in active cancer patients.
