VEGFA and hepatocellular carcinoma: A recent meta-analysis based on 11 studies evaluating the correlation between serum VEGF level and survival in patients with HCC confirmed these data, showing that serum VEGF levels had an unfavorable impact on both disease-free (HR = 2.27, 95%CI = 1.55–2.98) and overall survival (HR = 1.88, 95%CI = 1.46–2.30) [61].
