Abstract
Background: China’s Fujian Cervical Pilot Project (FCPP) transitioned cervical cancer screening from high-risk human papillomavirus (HR-HPV) nongenotyping to genotyping. We investigated the clinical impact of this introduction, comparing performance indicators between HR-HPV genotyping combined with cytology screening (HR-HPV genotyping period) and the previous HR-HPV nongenotyping combined with cytology screening (HR-HPV nongenotyping period). Methods: A retrospective population-based cohort study was performed using data from the FCPP for China. We obtained data for the HR-HPV nongenotyping period from 1 January 2012 to 31 December 2013, and for the HR-HPV genotyping period from 1 January 2014 to 31 December 2016. Propensity score matching was used to match women from the two periods. Multivariable Cox regression was used to assess factors associated with cervical intraepithelial neoplasia of grade 2 or worse (CIN2+). The primary outcome was the incidence of CIN2+ in women aged ⩾25 years. Performance was assessed and included consistency, reach, effectiveness, adoption, implementation and cost. Results: Compared with HR-HPV nongenotyping period, in the HR-HPV genotyping period, more CIN2+ cases were identified at the initial screening (3.06% versus 2.32%; p < 0.001); the rate of colposcopy referral was higher (10.87% versus 6.64%; p < 0.001); and the hazard ratio of CIN2+ diagnosis was 1.64 (95% confidence interval, 1.43–1.88; p < 0.001) after controlling for health insurance status and age. The total costs of the first round of screening (US$66,609 versus US$65,226; p = 0.293) were similar during the two periods. Higher screening coverage (25.95% versus 25.19%; p = 0.007), higher compliance with age recommendations (92.70% versus 91.69%; p = 0.001), lower over-screening (4.92% versus 10.15%; p < 0.001), and reduced unqualified samples (cytology: 1.48% versus 1.73%, p = 0.099; HR-HPV: 0.57% versus 1.34%, p < 0.001) were observed in the HR-HPV genotyping period. Conclusions: Introduction of an HR-HPV genotyping assay in China could detect more CIN2+ lesions at earlier stages and improve programmatic indicators. Evidence suggests that the introduction of HR-HPV genotyping is likely to accelerate the elimination of cervical cancer in China.

Abstract
Cervical cancer (CC) is one of the most deadly cancers in women, its current treatments still result in poor outcomes and developing the novel targets and therapeutic strategies are urgently needed. Recent studies have shown that anti-silencing function 1B (ASF1B) might be used as a new proliferation marker for cancer diagnosis and prognosis. However, the expression and function of ASF1B in cervical cancer remain unclear. Here, we induced ASF1B knockdown and overexpression in cervical cancer cell lines and detected the biological behavior changes in vitro. Furthermore, we established two murine models using stable ASF1B-shRNA HeLa cells or normal HeLa cells following AAV-shRNA-ASF1B administration to evaluate how suppression of ASF1B affects tumor growth. We showed that ASF1B functions as an oncogene in cervical cancer cells. Silence of ASF1B suppressed cervical cancer cell growth in vitro and in vivo, while, ASF1B overexpression accelerated cancer cell proliferation. Furthermore, ASF1B deficiency induced cell cycle arrest and apoptosis. Mechanistically, we found that ASF1B formed stable complexes with cyclin-dependent kinase 9 (CDK9), and positively regulated CDK9 stabilization. Taken together, tumorigenic ASF1B could be targeted to suppress cervical cancer tumor growth by inducing apoptotic cell death.

J Gynecol Oncol 2019; 30:e29. [PMID: 30887754 PMCID: PMC6424850 DOI: 10.3802/jgo.2019.30.e29] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2018] [Revised: 10/24/2018] [Accepted: 11/13/2018] [Indexed: 02/07/2023] Open
Abstract
OBJECTIVE To evaluate the polymerase chain reaction (PCR)-reverse-dot-blot (RDB) human papillomavirus (HPV) genotyping test as a feasible assay for the cervical cancer primary screening. METHODS In a hospital-based cohort, a total of 21,568 women were voluntarily enrolled from March 2009 to November 2016 for evaluating the 3 current cervical cancer screening strategies: co-test, cytology primary and high-risk HPV (HR-HPV) primary by using PCR-RDB HPV genotyping and liquid-based cytology (thinprep cytologic test [TCT]). Women with HR-HPV infection and/or abnormal cytology were referred for colposcopy, and the biopsy or conization was performed according to the American Society for Colposcopy and Cervical Pathology (ASCCP) guidelines. RESULTS Overall, 18.20% (3,935/21,568) of the women were detected as HR-HPV-positive, 5.04% (1,088/21,568) were diagnosed with cervical intraepithelial neoplasia 2 or higher (CIN2+), and 3.43% (739/21,568) with CIN3+. The cumulative incidence rates for CIN2+/CIN3+ in patients with HPV-16/18-positive were 48.28%/37.20%, while they were 0.86%/0.38%, 0.30%/0.15% and 0.18%/0.09% in cytology-negative, HR-HPV-negative and co-test-negative population, respectively. Using CIN2+ and CIN3+ as the observed endpoints, the sensitivity and negative predictive value (NPV) of HR-HPV genotyping as a primary screening tool were 90.99%/99.49% and 91.57%/99.80%. Moreover, using HR-HPV genotyping primary screening could detect the same more CIN2+/CIN3+ cases in baseline-detection as co-testing (990/700 vs. 991/701) and far more than cytology primary screening (903/656, p<0.05). It also achieved the lowest misdiagnosis rate (8.01%/5.02%). Although HPV genotyping primary screening required an increased number of colposcopies (2.75/3.89 per CIN2+/CIN3+ case), it yielded an acceptable rate. CONCLUSIONS The PCR-RDB HPV genotyping test is a cost-effective and beneficial cervical cancer primary screening for hospital-based opportunistic screening.

Abstract
Purpose To estimate the high-risk human papillomavirus (HR-HPV) prevalence in a hospital-based population using the Cervista® and to determine the clinical value and significance of Cervista for cervical cancer screening in Fujian Province, China. Patients and methods In a hospital-based population, a total of 10,771 women from the Fujian Province were screened for cervical cancer and precancerous lesions using the thinprep cytologic test (TCT) and/or the Cervista. Women with HR-HPV infection and/or abnormal TCT were referred for colposcopy and biopsy. Pathological diagnosis was used as the gold standard. Results The overall HR-HPV prevalence was 16.57%. Among 10,229 cases, 976 had abnormal cytology results, of which, the HR-HPV positivity rate was 60.35% in this opportunistic screening population. The most common HR-HPV infection style was a simple infection. The most common species was A9 which was also the most prevalent species in all age. The women with CIN2+ (high-grade squamous intraepithelial lesion [HSIL]), especially cancer, were mostly concentrated in the age from 51 to 60 years old. The peak of CIN1 (low-grade squamous intraepithelial lesion, LSIL) prevalence was in the women aged 31-40. When using CIN1+, CIN2+ and CIN3+ as observed endpoints, the sensitivities were 86.07%, 92.73%, and 93.30% and negative likelihood ratio (NPV) were 99.15%, 99.75% and 99.83%, respectively. Cervista and TCT co-testing achieved the highest sensitivity and the lowest NLR. Conclusion The Cervista could be easily introduced in clinical practice in combination with TCT for cervical cancer screening in China. Patients with species A9 infection require a more actively clinical intervention.

Prevalence and distribution of human papillomavirus genotypes among women with high-grade squamous intraepithelial lesion and invasive cervical cancer in Ganzhou, China. J Clin Lab Anal 2018; 33:e22708. [PMID: 30390349 DOI: 10.1002/jcla.22708] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2018] [Revised: 09/26/2018] [Accepted: 10/11/2018] [Indexed: 12/31/2022] Open
Abstract
BACKGROUND Human papillomavirus (HPV) infection can lead to the development of cervical cancer. This study assessed the genotype distribution of HPV of high-grade squamous intraepithelial lesion (HSIL) and invasive cervical cancer (ICC) in Ganzhou population. METHODS A total of 935 females who got HPV testing from January 2016 to July 2018 in the maternal and child health hospital of Ganzhou were enrolled in the study, including 806 HSIL and 129 ICC. HPV detection and genotyping were tested by HPV Geno-Array test kit. RESULTS The overall HPV-positive rate was 74.0% in Ganzhou. Among the HSIL and ICC patients, the positive rates of HPV detection were 75.6% and 64.3%. Among the HSIL individuals, the most prevalent hr-HPV genotype was HPV 16. And the 4 common subtypes in decreasing order were HPV 52, 58, 33, and 18. Of the ICC patients, the most frequently hr-HPV subtype was HPV 16 followed by 18, 52, 58, and 59. Among the squamous cell carcinoma (SCC) patients, for hr-HPV genotypes, HPV 16, 18, 52, 58, and 59 were five most common subtypes. In patients with adenocarcinoma (ADC), the most common hr-HPV genotype was HPV 18, followed by HPV 16, 52, 56, 68, 73. And, we found U-shaped and S-shaped curves in the HPV distribution of different age groups. CONCLUSION The prevalence and distribution of HPV genotypes in Ganzhou differed from other regions of China and Western countries. These results can serve as valuable reference for HPV vaccination programs for Ganzhou women.
