The risk for venous thromboembolism (VTE) is high in hospitalized cancer patients, and is associated with an elevated risk for recurrent thrombosis, bleeding complications, and use of health care resources. Thromboembolism is the second leading cause of death in hospitalized cancer patients. Thromboprophylaxis with unfractionated heparin or low-molecular-weight heparins has been clinically proven to reduce the risk for VTE and improve outcomes. However, VTE prophylaxis continues to be underprescribed in cancer patients. Recognizing the clinical burden of VTE in cancer patients, the National Comprehensive Cancer Network (NCCN) recently released guidelines for VTE prevention and management. These NCCN guidelines recommend evidence-based prophylactic anticoagulant therapy for all patients admitted to hospital with a diagnosis of cancer who do not have contraindications to anticoagulant use. However, there continue to be barriers to the implementation of clinical practice guidelines and appropriate use of VTE prophylaxis. Multifaceted active educational and electronic interventions are necessary to raise awareness and reduce the burden of cancer-associated thrombosis and its attendant consequences.
住院癌症患者发生静脉血栓栓塞(VTE)的风险很高,且与复发性血栓形成、出血并发症及医疗资源使用风险升高相关。血栓栓塞是住院癌症患者的第二大死因。普通肝素或低分子肝素进行血栓预防已被临床证明可降低VTE风险并改善预后。然而,癌症患者的VTE预防用药仍未得到充分处方。认识到癌症患者VTE的临床负担,美国国立综合癌症网络(NCCN)最近发布了VTE预防和管理指南。这些NCCN指南建议,对于所有因癌症诊断入院且无抗凝药物使用禁忌证的患者,采用基于证据的预防性抗凝治疗。然而,临床实践指南的实施及VTE预防的合理使用仍然存在障碍。需要多方面积极的教育和电子干预措施来提高认识,并减轻癌症相关血栓形成及其伴随后果的负担。
