    Abstract:
    To investigate the association between the susceptibility to cervical cancer and the single nucleotide polymorphisms of 5 tumor necrosis factor-α promoter genes (rs361525, rs1800629, rs1800750, rs1799964, and rs673) in Chinese women. A total of 946 peripheral blood samples were collected from women of Han Ethnicity in Shandong province. Of them, 452 were diagnosed with cervical squamous cell carcinomas. The study also included a control group of 494 healthy women. The targeted single nucleotide polymorphisms were analyzed by TaqMan probe method. (1) The rate of high-risk subtype human papillomavirus infection in exfoliated cervical epithelial cells was significantly higher in patients with cervical cancer than the control group (91.4% vs 10.3%, P < .01). The rate of human papillomavirus infection was lower in patients with carcinoma in situ than those with invasive carcinoma (77.9% vs 95.4%, P < .01). (2) There was a significant difference for rs361525 genotype (CC/CT/TT) between the control, carcinoma in situ, and invasive carcinoma groups ( P < .001). Both rs1800629 and rs1799964 genotypes (both GG/GA/AA) were also different between these groups ( P < .001 and P < .001). (3) The allele frequencies of rs361525, rs1800629, and rs1799964 were significantly correlated with the diagnosis of cervical cancer. The frequency of T allele in rs361525 was significantly higher for cervical cancer group (10.8%) than control group (3.8%; odds ratio = 3.04, 95% confidence interval = 1.76-5.25, P < .01). The frequency of A allele in rs1800629 was significantly higher for cervical cancer (29.9%) than control group (14.2%; odds ratio = 2.58, 95% confidence interval = 1.87-3.56, P < .01). The frequency of A allele in rs1799964 was also higher for cervical cancer group (38.3%) than control group (16.4%; odds ratio = 1.43, 95% confidence interval = 1.07-1.91, P < .05). The rs361525, rs1800629, and rs17999645 were significantly correlated with the diagnosis of cervical cancer.
