  • Beschreibung: <jats:title>Abstract</jats:title><jats:sec> <jats:title>Objective</jats:title> <jats:p>To systematically evaluate the relationship between vascular endothelial growth factor (VEGF) and prognosis of intrahepatic cholangiocarcinoma by meta-analysis.</jats:p> </jats:sec><jats:sec> <jats:title>Methods</jats:title> <jats:p>We systematically searched relevant studies in the databases of PubMed, Embase, Cochrane Library, CNKI, Wangfang, and Web of Science, with search dates limited to September 1, 2021. We extracted relevant data, including prognosis and clinicopathological features of patients with different expressions of VEGF in intrahepatic cholangiocarcinoma. The combined hazard ratio (HR), odds ratio (OR), and 95% confidence interval (CI) were calculated to evaluate the link strength between VEGF and prognosis of cholangiocarcinoma patients.</jats:p> </jats:sec><jats:sec> <jats:title>Results</jats:title> <jats:p>A total of 7 eligible studies with 495 patients were included in this meta-analysis. The results showed that the high expression of VEGF was significantly related to poor overall survival (OS) (HR = 1.93, 95% CI 1.52–2.46, <jats:italic>P</jats:italic> &lt; 0.05) in patients with intrahepatic cholangiocarcinoma. Moreover, high expression of VEGF in tumor tissues associated with lymph node metastasis (LNM) (OR = 6.79, 95% CI 3.93–11.73, <jats:italic>P</jats:italic> &lt; 0.05) and advanced TNM stage (OR = 4.35, 95% CI 2.34–8.07, <jats:italic>P</jats:italic> &lt; 0.05) in intrahepatic cholangiocarcinoma. Sensitivity analysis shows that the meta-analysis results are stable and reliable.</jats:p> </jats:sec><jats:sec> <jats:title>Conclusion</jats:title> <jats:p>The expression of VEGF is related to the OS of patients with intrahepatic cholangiocarcinoma, and the OS of patients with high expression of VEGF is shorter. VEGF may be a novel predictor of intrahepatic cholangiocarcinoma patients.</jats:p> </jats:sec><jats:sec> <jats:title>Trial registration</jats:title> <jats:p>PROSPERO (<jats:ext-link xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="uri" xlink:href="https://www.crd.york.ac.uk/PROSPERO/display_record.php?RecordID=297443">CRD42022297443</jats:ext-link>).</jats:p> </jats:sec>
