The significance of human papillomavirus receptors related genes
variants in cervical cancer screening: a longitudinal study of Chinese
population
Abstract
Objective To investigate the relationship between single nucleotide
polymorphisms (SNPs) in human papillomavirus (HPV) receptor gene and HPV
susceptibility and the outcomes in Chinese women. Study design A cohort
study. Setting Lishui, Zhejiang, China. Population 3066 women were
recruited. Methods 29 SNP sites of HPV receptor gene on women with
available cytology residual samples were detected. Main outcome measures
Develop to cervical intraepithelial neoplasia 2 and worse (CIN2+).
Results: 2938 women with sufficient cytology samples performed SNP sites
detection. Rs16894821 [GG vs. AA: OR =1.71 (1.08-2.69)] and rs724236
[TT vs. AA: OR=1.73 (1.14-2.62)] in SDC2 increased the HPV
susceptibility. TT genotype of rs2575712 in SDC2 was associated with an
increased HPV 16/18 susceptibility [OR=2.78 (1.22-6.36)]. Four SNPs
(rs1047057 and rs10510097, rs2575735, and rs878949) were significantly
associated with HPV persistent infection. In addition, the frequencies
of genotype of rs16894821 under recessive model [OR=2.40
(1.12-5.15)] in SDC2, and rs11199993 under dominant model [OR=1.64
(1.01-2.68)] in FGFR2 were significantly associated with the disease
progression. Importantly, we found that HPV test in combination with
SNPs with sensitivity of 0.51 (0.36-0.66) and specificity of 0.96
(0.96-0.97) in predicting CIN2+ on women with non-HPV16/18+, which had
similar performance to HPV test combined with cytology test with
sensitivity of 0.44 (0.30-0.60) and specificity of 0.98 (0.97-0.99).
Conclusion: Gene variants in HPV receptor related gene may influence the
HPV susceptibilities and the outcome of HPV infection. HPV combined with
SNPs is a promising alternative to HPV test combined with cytology test
in patients with non-HPV16/18 infection.
