Introduction: The aim of this study is to evaluate whether the administration of renin-angiotensin system (RAS) inhibitors, angiotensin-I converting enzyme inhibitors (ACEIs) or angiotensin II receptor blockers (ARBs), is associated with treatment outcome in patients with esophageal squamous cell carcinoma. Materials and methods: A total of 141 esophageal squamous cell carcinoma patients receiving esophagectomy were identified, and were divided into two groups: an ACEI/ARB group (n=20), and a non-ACEI/ARB group (n=121). The effect of ACEIs or ARBs on cell proliferation and vascular endothelial growth factor (VEGF) secretion of esophageal squamous cell carcinoma cell lines, CE81T/VGH and TE2, were investigated by 3-(4.5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay and Enzyme-linked immunosorbent assay (ELISA), respectively. Results: Use of ACEI/ARB (p=0.032), pathologic T stage (p<0.001), pathologic N stage (p=0.012), tumor stage (p=0.006), and tumor location (p=0.032) were significantly associated with superior overall survival. In multivariate comparison, use of ACEI/ARB (p=0.006), tumor stage (p=0.002), and tumor location (p=0.014) represented the independent prognosticators of superior overall survival. In cell lines, ACEIs/ARBs inhibit cell proliferation and VEGF secretion in a dose-dependent manner. Conclusions: ACEIs/ARBs administration is independently associated with superior overall survival in patients with esophageal squamous cell carcinoma receiving esophagectomy. Our data support further investigation of the role of RAS inhibitors as a potential therapy in esophageal squamous cell carcinoma.
