Objective: This study aimed to investigate the association of stromal cellYderived factor 1 (SDF-1) gene polymorphisms with the neoplastic lesions of uterine cervix in Mid-Taiwan women. Materials and Methods: Four hundred ninety-eight blood samples were collected from 161 patients with neoplasia of uterine cervix, including 76 cancer patients, 61 patients with high-grade dysplasia, and 24 with low-grade dysplasia, and 337 healthy controls who lived in Mid-Taiwan. Polymorphism of the SDF-1 gene was examined using polymerase chain reactionYrestriction fragment length polymorphism. Results: For SDF-1 gene polymorphisms, the wild-type homozygous alleles (G/G) yielded 100- and 193-bp products, the heterozygous alleles (G/A) yielded 100-, 193- and 293-bp products, whereas the mutated-type homozygous alleles (A/A) yielded a 293-bp product. We found no significant difference in genotypes or alleles distribution of SDF-1 polymorphisms between patients with cervical neoplasia and healthy women (P = 0.530). Compared with the homozygous GG subgroup, GA and AA subgroups do not increase the risk of cervical neoplasia. Conclusions: Although the expression of SDF-1 was reported to be significantly increased in cervical carcinogenesis in previous studies, our results, however, show that SDF-1 gene polymorphism could not be considered as a factor related to an increased susceptibility to cervical neoplasia.
