Single nucleotide polymorphisms in the PRDX3 and RPS19 and risk of HPV persistence and cervical precancer/cancer.

ABSTRACT: Host genetic factors might affect the risk of progression from infection with carcinogenic human papillomavirus (HPV), the etiologic agent for cervical cancer, to persistent HPV infection, and hence to cervical precancer and cancer.We assessed 18,310 tag single nucleotide polymorphisms (SNPs) from 1113 genes in 416 cervical intraepithelial neoplasia 3 (CIN3)/cancer cases, 356 women with persistent carcinogenic HPV infection (median persistence of 25 months) and 425 randomly selected women (non-cases and non-HPV persistent) from the 10,049 women from the Guanacaste, Costa Rica HPV natural history cohort. For gene and SNP associations, we computed age-adjusted odds ratio and p-trend. Three comparisons were made: 1) association with CIN3/cancer (compared CIN3/cancer cases to random controls), 2) association with persistence (compared HPV persistence to random controls), and 3) progression (compared CIN3/cancers with HPV-persistent group). Regions statistically significantly associated with CIN3/cancer included genes for peroxiredoxin 3 PRDX3, and ribosomal protein S19 RPS19. The single most significant SNPs from each gene associated with CIN3/cancer were PRDX3 rs7082598 (P(trend)<0.0001), and RPS19 rs2305809 (P(trend)=0.0007), respectively. Both SNPs were also associated with progression.These data suggest involvement of two genes, RSP19 and PRDX3, or other SNPs in linkage disequilibrium, with cervical cancer risk. Further investigation showed that they may be involved in both the persistence and progression transition stages. Our results require replication but, if true, suggest a role for ribosomal dysfunction, mitochondrial processes, and/or oxidative stress, or other unknown function of these genes in cervical carcinogenesis.

Project description:ImportanceAs cervical cancer screening transitions to primary human papillomavirus (HPV) testing, effective triage and management of HPV-positive women is critical to avoid unnecessary colposcopy referral and associated harms while maintaining high sensitivity for cervical precancer. Triage with p16/Ki-67 dual-stain (DS) testing has shown high sensitivity and specificity for detection of cervical precancers; however, longitudinal studies are needed to determine the long-term risk of precancer following a negative DS result.ObjectiveTo evaluate the longitudinal performance of p16/Ki-67 DS triage for detection of cervical precancer in HPV-positive women over 5 years of follow-up in the context of clinical management thresholds.Design, setting, and participantsProspective cohort study of HPV-positive women 30 years or older undergoing routine cervical cancer screening in 2012 with HPV and Papanicolaou (hereinafter "cytology") co-testing within the Kaiser Permanente Northern California health care system. Follow-up of medical records was conducted through 2017.ExposuresAll p16/Ki-67 DS testing was performed on residual SurePath material, and slides were evaluated for p16/Ki-67 positivity.Main outcomes and measuresHistological end points were ascertained from the clinical database through 2017. We estimated 5-year cumulative risks of cervical intraepithelial neoplasia grades of 2 or worse (≥CIN2) or grades 3 or worse (≥CIN3) by baseline DS and cytology at yearly intervals using Logistic Weibull models. Risks were compared with clinical management thresholds for colposcopy referral and a 1-year return interval.ResultsAmong the 1549 HPV-positive women in this study, the mean age at enrollment was 42.2 years, and the median follow-up time was 3.7 years (range, 0.2-5.4 years). Positive DS results were associated with significantly higher cumulative 5-year risks of ≥CIN2 compared with abnormal cytology (31.0%; 95% CI, 27.2%-35.3% vs 25.0%; 95% CI, 21.7%-28.7%; P = .03). Women with DS-negative findings had significantly lower 5-year risks of ≥CIN2 compared with women with normal cytology (8.5%; 95% CI, 6.5%-11.1% vs 12.3%; 95% CI, 9.8%-15.4%; P = .04). In DS-negative women, the risks of both ≥CIN2 and ≥CIN3 remained below the colposcopy referral threshold for all 5 years, crossing the 1-year return threshold at 3 years.Conclusions and relevanceTriage with p16/Ki-67 DS provides better long-term risk stratification than cytology over 5 years. The low risk of cervical precancer in p16/Ki-67 DS-negative women permits safe extension of follow-up intervals for 3 years.

Project description:ContextUS cervical cancer screening guidelines for human immunodeficiency virus (HIV)-uninfected women 30 years or older have recently been revised, increasing the suggested interval between Papanicolaou (Pap) tests from 3 years to 5 years among those with normal cervical cytology (Pap test) results who test negative for oncogenic human papillomavirus (HPV). Whether a 3-year or 5-year screening interval could be used in HIV-infected women who are cytologically normal and oncogenic HPV-negative is unknown.ObjectiveTo determine the risk of cervical precancer or cancer defined cytologically (high-grade squamous intraepithelial lesions or greater [HSIL+]) or histologically (cervical intraepithelial neoplasia 2 or greater [CIN-2+]), as 2 separate end points, in HIV-infected women and HIV-uninfected women who at baseline had a normal Pap test result and were negative for oncogenic HPV.Design, setting, and participantsParticipants included 420 HIV-infected women and 279 HIV-uninfected women with normal cervical cytology at their enrollment in a multi-institutional US cohort of the Women's Interagency HIV Study, between October 1, 2001, and September 30, 2002, with follow-up through April 30, 2011. Semiannual visits at 6 clinical sites included Pap testing and, if indicated, cervical biopsy. Cervicovaginal lavage specimens from enrollment were tested for HPV DNA using polymerase chain reaction. The primary analysis was truncated at 5 years of follow-up.Main outcome measureFive-year cumulative incidence of cervical precancer and cancer.ResultsNo oncogenic HPV was detected in 369 (88% [95% CI, 84%-91%]) HIV-infected women and 255 (91% [95% CI, 88%-94%]) HIV-uninfected women with normal cervical cytology at enrollment. Among these oncogenic HPV-negative women, 2 cases of HSIL+ were observed; an HIV-uninfected woman and an HIV-infected woman with a CD4 cell count of 500 cells/μL or greater. Histologic data were obtained from 4 of the 6 clinical sites. There were 6 cases of CIN-2+ in 145 HIV-uninfected women (cumulative incidence, 5% [95% CI, 1%-8%]) and 9 cases in 219 HIV-infected women (cumulative incidence, 5% [95% CI, 2%-8%]). This included 1 case of CIN-2+ in 44 oncogenic HPV-negative HIV-infected women with CD4 cell count less than 350 cells/μL (cumulative incidence, 2% [95% CI, 0%-7%]), 1 case in 47 women with CD4 cell count of 350 to 499 cells/μL (cumulative incidence, 2% [95% CI, 0%-7%]), and 7 cases in 128 women with CD4 cell count of 500 cells/μL or greater (cumulative incidence, 6% [95% CI, 2%-10%]). One HIV-infected and 1 HIV-uninfected woman had CIN-3, but none had cancer.ConclusionThe 5-year cumulative incidence of HSIL+ and CIN-2+ was similar in HIV-infected women and HIV-uninfected women who were cytologically normal and oncogenic HPV-negative at enrollment.

Project description:HPV infrequently persists and progresses to cervical cancer. We examined host genetic factors hypothesized to play a role in determining which subset of individuals infected with oncogenic human papillomavirus (HPV) have persistent infection and further develop cervical pre-cancer/cancer compared to the majority of infected individuals who will clear infection.We evaluated 7140 tag single nucleotide polymorphisms (SNPs) from 305 candidate genes hypothesized to be involved in DNA repair, viral infection and cell entry in 416 cervical intraepithelial neoplasia 3 (CIN3)/cancer cases, 356 HPV persistent women (median: 25 months), and 425 random controls (RC) from the 10,049 women Guanacaste Costa Rica Natural History study. We used logistic regression to compute odds ratios and p-trend for CIN3/cancer and HPV persistence in relation to SNP genotypes and haplotypes (adjusted for age). We obtained pathway and gene-level summary of associations by computing the adaptive combination of p-values. Genes/regions statistically significantly associated with CIN3/cancer included the viral infection and cell entry genes 2',5' oligoadenylate synthetase gene 3 (OAS3), sulfatase 1 (SULF1), and interferon gamma (IFNG); the DNA repair genes deoxyuridine triphosphate (DUT), dosage suppressor of mck 1 homolog (DMC1), and general transcription factor IIH, polypeptide 3 (GTF2H4); and the EVER1 and EVER2 genes (p<0.01). From each region, the single most significant SNPs associated with CIN3/cancer were OAS3 rs12302655, SULF1 rs4737999, IFNG rs11177074, DUT rs3784621, DMC1 rs5757133, GTF2H4 rs2894054, EVER1/EVER2 rs9893818 (p-trends</=0.001). SNPs for OAS3, SULF1, DUT, and GTF2H4 were associated with HPV persistence whereas IFNG and EVER1/EVER2 SNPs were associated with progression to CIN3/cancer. We note that the associations observed were less than two-fold. We identified variations DNA repair and viral binding and cell entry genes associated with CIN3/cancer. Our results require replication but suggest that different genes may be responsible for modulating risk in the two critical transition steps important for cervical carcinogenesis: HPV persistence and disease progression.

Project description:In this report, we describe a case control study in a Chinese population aimed at identifying possible associations between susceptibility to cervical cancer and single nucleotide polymorphisms in XRCC1 194C>T, XRCC1 280G>A, XRCC1 399G>A, ERCC2 751A>C, ERCC2 156C>A, ERCC1 118C>T, PARP1 762T>C, RAD51 135G>C and HER2 655A>G. The cases comprised 154 patients: 80 cervical squamous cell carcinomas (SCCs), 2 adenocarcinomas and 72 cervical intraepithelial neoplasias (CINs). A total of 177 healthy women were recruited as the controls. A significant association was found between ERCC1 118C>T and SCC in the additive genetic model [odds ratio (OR)=1.711; 95% confidence interval (CI), 1.089-2.880; p=0.021] and the dominant genetic model (OR=1.947; 95% CI, 1.056-3.590; p=0.033). Among women with a smoking family member, ERCC1 118C>T increased SCC risk in the additive model (OR=2.800; 95% CI, 1.314-5.968; p=0.008). For women who had first intercourse before 22 years of age, XRCC1 280G>A was found to act as a protective factor for SCC under the additive model (OR=0.228; 95% CI, 0.058-0.900; p=0.035), while RAD51 135G>C was a risk factor for CIN (OR=4.246; 95% CI, 1.335-13.502; p=0.014). For women who had first intercourse after 22 years of age, the additive genetic model showed RAD51 135G>C (OR=0.359; 95% CI, 0.138-0.934; p=0.036) and HER2 655A>G (OR=0.309; 95% CI, 0.098-0.972; p=0.045) to be protective factors for SCC. XRCC1 399G>A increased CIN risk among women who first gave birth before the age of 22 in the additive genetic model (OR=4.459; 95% CI, 1.139-17.453; p=0.032). For those who first gave birth after age 22, ERCC1 118C>T was found to be a risk factor for SCC in the additive genetic model (OR=1.884; 95% CI, 1.088-3.264; p=0.024). A significant interaction was observed between RAD51 135G>C and age at first intercourse (p(interaction)=0.033 for SCC, p(interaction)=0.021 for CIN), as well with sexual partner number (p(interaction)=0.001 for SCC). The interaction between HER2 655A>G and age at first intercourse, ERCC2 156C>A and family smoking status and XRCC1 280G>A and alcohol consumption were significant, with p(interaction)=0.023 for SCC, p(interaction)=0.021 for CIN and p(interaction)=0.025 for SCC, respectively.
