Abstract:
CHEK1 gene is known to play an important role in tumor progression by cell cycle control. However, the association between CHEK1 and the prognosis of esophageal squamous cell carcinoma (ESCC) is unclear. In this study, we explored the association between genetic variants in CHEK1 gene and prognosis of ESCC patients treated with radical resection. A total of 131 thoracic ESCC patients who underwent radical resection were included in this retrospective study and genotyped using the MassArray method. According to the univariate Cox hazard analysis, the GT/TT genotype of CHEK1 rs555752 was shown to be strongly related to a decreased overall survival (OS) (HR=2.560, 95% CI: 1.415-4.631, P=0.002) and disease-free survival (DFS) (HR=2.160, 95% CI: 1.258-3.710, P=0.005). Furthermore, according to the multivariate Cox hazard analysis and multiple testing, patients with the GT/TT genotype of CHEK1 rs555752 had a notably decreased OS (HR=2.735, 95% CI: 1.468-5.096, P=0.002, Pc=0.006) and DFS (HR=2.282, 95% CI: 1.292-4.023, P=0.004, Pc=0.012). In conclusion, genetic variants of the CHEK1 gene are significantly related to OS and DFS of ESCC patients, and may therefore be predictors of the prognosis of thoracic ESCC after surgery.
