Abstract:
OBJECTIVETo investigate the association between apoptosis genes Fas/Fas L promoter polymorphisms and the risk of the development of cervical cancer.
METHODSBlood samples were collected from 314 cases with primary cervical cancer and 615 healthy controls. Genotypes of Fas/Fas L genes were determined by polymerase chain reaction-based restriction fragment length polymorphism. The associations with the risk of cervical cancer and impact of clinicopathological characteristics were estimated by logistic regression.
RESULTSFas L-844CC genotype was significantly associated with increased risk of cervical cancer compared with Fas L-844TC or -TT genotype (OR = 3.05; P < 0.01). However, there was no significant difference of Fas-670A/G or -1377G/A genotypes. Interaction of genetic polymorphism between Fas and Fas L was observed. Stratification analysis revealed that Fas-670G or -1377A allele was significantly higher in squamous carcinoma in situ (OR = 1.77 or 1.93; P < 0.05) while Fas L-844CC genotype had an increased risk of invasive squamous carcinoma compared with that of Fas L-844TT genotype (OR = 3.33; P < 0.01). No significant associations were observed between polymorphisms in Fas/Fas L and clinical FIGO stage, cell differentiation, size of tumors, serum squamous cell carcinoma antigen value at the diagnosis and so on.
CONCLUSIONThe results of this study suggest that genetic polymorphisms of Fas and Fas L in apoptotic pathway are associated with the risk of development of cervical carcinoma.
