Objective To investigate the potential association between XRCC1 and XRCC3 gene polymor-phisms and susceptibility to cervical cancer within populations infected with high-risk human papillomavirus(HPV).Methods A cohort of 176 cervical cancer patients with high-risk HPV infection,diagnosed at the First People's Hospital of Kashgar Region between January 2021 and January 2023,were enrolled as the study group.Concurrently,177 women infected with high-risk HPV but without cervical cancer were enrolled as the control group.All participants were followed up,and genotyping along with HPV subtyping was conducted for subsequent analysis.Results The XRCC1 Arg399Gln genotype showed a significant association with cervical cancer risk among individuals infected with specific HPV subtypes(e.g.,HPV-16,-18,-52,and-58),but no significant correlation was observed with the number of concurrent HPV infections.Compared to non-carriers,individuals carrying the XRCC1 Arg399Gln genotype exhibited an increased risk of cervical cancer,particularly among those infected with HPV-16,-18,-52,or-58.Statistically significant differences were found between the control group and the cervical cancer group for the XRCC1 Arg280His(P<0.001)and XRCC3 Thr241Met(P<0.05)genotypes;however,no significant differences were observed for XRCC1 Arg194Trp and XRCC1 Arg399Gln polymorphisms(P>0.05).Further analysis revealed that the XRCC1 Arg280His polymorphism was associated with a 3.57-fold higher risk of cervical cancer(OR=3.57,95%CI:1.99～6.43),while XRCC1 Arg194Trp showed no significant association(P>0.05).Additionally,XRCC1 Arg399Gln was associated with a reduced risk(OR=0.57,95%CI:0.34～0.96),and XRCC3 Thr241Met was linked to a decreased risk of cervical cancer(OR=0.22,95%CI:0.06～0.84).Conclusions In the HPV-infected population of Kashgar,the XRCC1 Arg280His polymorphism is significantly associated with an increased risk of cervical cancer(OR=3.57),whereas the XRCC3 Thr241Met(GG)genotype exhibits a protective effect(OR=0.16).The XRCC1 Arg399Gln variant demonstrates a protective association specifically among TT homozygotes(OR=0.57).In contrast,the XRCC1 Arg194Trp polymorphism does not show a statistically significant association with cervical cancer risk.
