Background: The gene's 3′ untranslated region of stromal cell-derived factor1 (SDF-1/ CXC chemokine ligand 12 (CXCL12)) contains a polymorphism, known as SDF1-3′A at location 801, and has been linked to various types of cancers. The present study aimed to evaluate the relationship between this polymorphism and genetic predisposition to endometrial cancer.Method: In this case-control study, DNA was extracted from blood samples of 108 endometrial cancer patients and 123 healthy individuals through salting out method. Genotyping was done by restriction fragment length polymorphism-polymerase chain reaction method, and the data were analyzed using chi-square test.Results: A total number of 67 (62%) patients emerged as GG genotypes, 35 (32.4%) with GA, and 6 (5.6%) with AA genotypes. The frequency of GG, GA and AA in healthy control group was found to be 68 (55.3%), 50 (40.6%) and 5 (4.1%), respectively. Furthermore, the most frequent allele in both patient (169 (78.25%)) and control (186 (75.6%)) groups was G allele. However, no significant difference was observed between genotypes and alleles frequencies between the two groups. Furthermore, no significant association was observed between genotypes distribution and menopausal status (P = 0.70), tumor size (P = 0.62), degree of tumor differentiation (P = 0.74), stage (P = 0.35), tumor type (P = 0.22), and myometrial invasion (P = 0.22).Conclusion: Our results show that SDF1-3′A at location 801 may not enhance the risk of endometrial cancer. However, further research with a larger sample size is required to understand the molecular behavior of the SDF-1 gene polymorphism in endometrial cancer.
