Cervical neoplasia is one of the most prevalent malignant neoplasms worldwide. Ribonucleotide reductase 1 (RRM1) is thought to play an essential role in modulating the development and progression of cervical neoplasia. Two novel genetic polymorphisms, RRM1 −756T>C and −269 C>A, are significantly correlated with RRM1 expression. Some epidemiological studies have demonstrated that genetic variants play a crucial role in susceptibility to cervical cancer. The present study aimed to identify the genetic polymorphisms RRM1 −756T>C and −269 C>A in patients with cervical neoplasia and healthy controls. In total, 493 subjects, comprising 324 healthy controls and 169 patients with cervical neoplasia, were enrolled for this study. The allelic discrimination of the RRM1 −756T>C (rs11030918) and −269C>A (rs12806698) polymorphisms was assessed using the ABI StepOne™ real-time polymerase chain reaction system and analyzed using Software Design Specification (SDS), Version 3.0, software with TaqMan assays. The risk of cervical cancer was examined, revealing adjusted odds ratios and 95% confidence intervals of 1.25 [0.51, 3.08] and 1.09 [0.43, 2.78] for individuals with CC alleles of RRM1 −756T>C and for individuals with AA alleles of RRM1 −269C>A genetic polymorphisms, respectively, compared to individuals with wild-type RRM1 genetic polymorphisms. No significant genetic interaction effect was observed in susceptibility to cervical neoplasia, and no association was found between genetic polymorphisms and clinical statuses of invasive cervical cancer. The genetic polymorphisms RRM1 −756T>C and −269C>A may not be a factor for susceptibility to cervical neoplasia.
