Abstract
Esophageal cancer is a common cause of death from cancer in men and the eighth most prevalent cancer globally. The morbidity and mortality rates are four times higher in men than in women. Genetic factors are among the susceptibility factors for squamous cell carcinoma of the esophagus. The rs2032582 polymorphism is a triallelic missense variant of the ABCB1 gene, that has been reported to be associated with several cancers. Here we have explored the association of the ABCB1 rs2032582 polymorphism with esophageal squamous cell carcinoma (ESCC) for the first time in a total of 251 subjects, with and without ESCC. Data from patient's record were obtained from the Mashhad University of Medical Sciences, and were used to recruit ESCC patients into the study. A total of 89 ESCC patients and 162 healthy controls were included. DNAs were extracted and genotyped using a TaqMan real-time PCR-based method. Caplan Meier method was applied to analyze patients overall survival, and progression-free survival and log-rank were used in order to compare the results. Logistic regression was used to calculate the association between risk of ESCC and different genotypes. Our data showed that patients with ESCC had a higher frequency of a T/A (TT/TA/AA) genotype for rs2032592 than individuals with GG-genotype. There were no associations between BMI and genotypic frequencies. Furthermore patients with TT/TA/AA genotypes had a poorer disease-free survival (P = 0.016) in comparison with GG genotype. We found a significant association of the ABCB1 rs2032582 polymorphism with prognosis, although further studies in a larger and multicenter setting are needed to value these findings. © 2019 IUBMB Life, 71(9):1252-1258, 2019.
