Abstract: The p14ARF/MDM2/ TP53 pathway is known to play an important role in tumor progression by cell cycle control, although the association between this pathway and the prognosis of esophageal squamous cell carcinoma (ESCC) is unclear. In this study, we explored the association between genetic variants in the p14ARF/MDM2/TP53 pathway and prognosis in ESCC patients with radical resection. 124 ESCC patients with radical resection were included in this retrospective study and genotyped using the MassArray method. According to multivariate Cox hazard analysis and multiple testing, the TC/CC genotype of p14ARF rs3814960 was shown to be strongly related to a decreased overall survival (OS) (HR = 2.77, 95% CI: 1.33–5.75, P = 0.006, Pc = 0.030) and disease-free survival (DFS) (HR = 2.45, 95% CI: 1.30–4.61, P = 0.005, Pc = 0.025). Moreover, patients with the DEL/A +AA genotype of MDM2 rs34886328 had a notably increased OS (HR = 0.27, 95% CI: 0.13–0.56, P = 4.7×10−4, Pc = 0.003) and DFS (HR = 0.22, 95% CI: 0.11–0.43, P = 1.1×10−5, Pc = 6.6×10−5). We also found that these two SNPs had a cumulative effect on the prognosis of ESCC, with the OS (P
