Abstract:

Objective Risk factors for catheter-related thrombosis in totally implantable venous access ports （TIVAP） in tumor patients were analyzed by systematic analysis. Methods Computerized retrieval of PubMed，EMbase，Web of Science，the Cochrane Library，CBM，WanFang Data，CNKI and VIP databases was carried out. Case-control studies and cohort studies about TIVAP catheter-related thrombosis risk factors in tumor patients were collected from the database establishment to August 2021. 2 researchers independently screened the literature，extracted data，and evaluated the risk of bias in the included studies. Meta-analysis was performed using RevMan5.3 software. Results A total of 22 studies were included，including 4 case-control studies and 18 cohort studies，with a total of 10526 patients. The results of meta-analysis showed that tumor clinical stage[OR=3.06，95%CI（2.16，4.35），P<0.001]，implantation location[OR=0.69，95%CI（0.53，0.89），P=0.005]，body mass index（BMI）[OR=1.95，95%CI（1.21，3.13），P=0.006]，tumor metastasis[OR=2.72，95%CI（1.38，5.38），P=0.004]，infusion port material [OR=0.73，95%CI（0.56，0.95），P=0.020]，hypercoagulable state[OR=2.69，95%CI（1.94，3.73），P<0.001] and diabetes history[OR=0.50，95%CI（0.33，0.76），P=0.001] are independent risk factors for catheter-related thrombosis in tumor patients with TIVAP. Conclusion Current evidence shows that the location，material，tumor stage，tumor metastasis，BMI，concomitant hypercoagulability，and diabetes are independent risk factors for TIVAP catheter-related thrombosis in cancer patients. Clinical nursing care should be strengthened for high-risk patients with the above risk factors，in order to reduce the incidence of catheter-related thrombosis and improve the clinical outcomes of patients.

摘要：

目的 通过系统评价的方法分析肿瘤患者完全植入式静脉输液港（totally implantable venous access ports，TIVAP）导管相关性血栓形成的危险因素。方法 计算机检索PubMed、Embase、Web of Science、Cochrane Library、中国生物医学文献数据库、中国知网、万方数据库和维普数据库，检索有关肿瘤患者TIVAP导管相关性血栓形成危险因素的病例对照研究和队列研究，检索时限均为建库至2021年8月。由2名研究者独立筛选文献、提取资料并评价纳入研究的偏倚风险后，采用RevMan 5.3软件进行Meta分析。结果 共纳入22项研究，包括4项病例对照研究和18项队列研究，共10 526例患者。Meta分析结果显示，肿瘤临床分期Ⅲ~Ⅳ期[OR=3.06，95%CI（2.16，4.35），P<0.001]、胸壁静脉植入[OR=0.69，95%CI（0.53，0.89），P=0.005]、体重指数≥25[OR=1.95，95%CI（1.21，3.13），P=0.006]、肿瘤发生转移[OR=2.72，95%CI（1.38，5.38），P=0.004]、硅胶材质导管[OR=0.73，95%CI（0.56，0.95），P=0.020]、高凝状态[OR=2.69，95%CI（1.94，3.73），P<0.001]及糖尿病史[OR=0.50，95%CI（0.33，0.76），P=0.001]是肿瘤患者TIVAP导管相关性血栓形成的独立危险因素。结论 输液港植入位置及其材质、肿瘤临床分期、肿瘤发生转移、体重指数、伴随高凝状态、糖尿病史为肿瘤患者TIVAP导管相关性血栓形成的影响因素。对具有以上影响因素的高危患者应加强临床护理，以降低导管相关性血栓发生率，改善患者临床预后。
