J Infect Public Health 2023; 16:1531-1536. [PMID: 37562080 DOI: 10.1016/j.jiph.2023.07.013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2023] [Revised: 06/18/2023] [Accepted: 07/17/2023] [Indexed: 08/12/2023] Open
Abstract
BACKGROUND To assess the prevalence and characteristics of human papillomavirus (HPV) genotypes and its associated cervical lesions in Guangzhou, China, which may be useful for adjusting area-specific cervical cancer prevention and control strategies. METHODS A total of 58630 women were enrolled. Cervical specimens were collected for HPV DNA testing and/or cervical cytology. Patients with visible cervical lesions or abnormal screening results underwent further cervical biopsies. RESULT The overall HPV positive rate was 14.07%. The top five genotypes in Guangzhou were HPV 52 (3.06%), HPV 16 (2.28%), HPV 58 (1.80%), HPV 51 (1.32%), and HPV 39 (1.15%). The prevalence of overall HPV and vaccine-targeted HPV genotypes showed a significantly decreasing trend from 2016 to 2019 (P < 0.05). While, the infection rate of HPV 35 increased significantly during this time (P = 0.015). The age-specific prevalence of any HPV genotypes showed a bimodal curve, which peaked firstly among the < 20 y age group, and then peaked secondly among the > 59 y age group. Among HPV-positive women, the proportions of HSIL and cervical cancer increased significantly with age (P < 0.05). Among > 59 y age group, 9.35% HPV-positive cases were diagnosed as cervical cancer. HPV 16/18 was the most common cause of cervical cancer. While, the percentage of non-HPV 16/18 infection among cervical cancer patients increased over time, from 15.21% in 2015 to 26.32% in 2019 (P = 0.010). Besides that, the prevalence of non-HPV 16/18 genotypes among cervical cancer patients significantly increased with age, which peaked at the > 59 y age group (P = 0.014). CONCLUSION Although the prevalence of any HPV and vaccine-targeted HPV genotypes decreased significantly with time, it is still important to follow the HPV genotypes and their associated cancer risk after the large-scale popularization of HPV vaccine. And age should be taken into consideration in screening strategies and risk-based management of cervical cancer in Guangzhou.

Value of a catch-up HPV test in women aged 65 and above: A Danish population-based nonrandomized intervention study. PLoS Med 2023; 20:e1004253. [PMID: 37410699 PMCID: PMC10325045 DOI: 10.1371/journal.pmed.1004253] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/09/2022] [Accepted: 05/31/2023] [Indexed: 07/08/2023] Open
Abstract
BACKGROUND High-risk human papillomavirus (HPV) test is replacing cytology as the primary cervical cancer screening test due to superior sensitivity, but in most countries women ≥65 years have never had an HPV test despite they account for around 50% of cervical cancer deaths. We explored the effect of a catch-up HPV test among 65- to 69-year-old women without previous record of HPV-based screening. METHODS AND FINDINGS This population-based nonrandomized intervention study (quasi-experimental design) included Danish women aged 65 to 69 with no record of cervical cancer screening in the last ≥5.5 years and no HPV-exit test at age 60 to 64 at the time of study inclusion. Eligible women residing in the Central Denmark Region were invited for HPV screening either by attending clinician-based sampling or requesting a vaginal self-sampling kit (intervention group, n = 11,192). Women residing in the remaining four Danish regions received standard care which was the opportunity to have a cervical cytology collected for whatever reason (reference group, n = 33,387). Main outcome measures were detection of cervical intraepithelial neoplasia (CIN) grade 2 or worse (CIN2+) per 1,000 women eligible for the screening offer and the benefit-harm ratio of the intervention and standard practice measured as the number of colposcopies needed to detect one CIN2+ case. The minimum follow-up time was 13 months for all tested women (range: 13 to 25 months). In the intervention group, 6,965 (62.2%) were screened within 12 months from the date of study inclusion and 743 (2.2%) women had a cervical cytology collected in the reference group. The CIN2+ detection was significantly higher in the intervention group (3.9, 95% confidence interval (CI): [2.9, 5.3]; p < 0.001; n = 44/11,192) as compared to the reference group (0.3, 95% CI: [0.2, 0.6]; n = 11/33,387). For the benefit-harm ratio, 11.6 (95% CI: [8.5, 15.8]; p = 0.69; n = 511/44) colposcopies were performed to detect one CIN2+ in the intervention group as compared to 10.1 (95% CI: [5.4, 18.8]; n = 111/11) colposcopies in the reference group. The study design entails a risk of confounding due to the lack of randomization. CONCLUSIONS The higher CIN2+ detection per 1,000 eligible women in the intervention group supports that a catch-up HPV test could potentially improve cervical cancer prevention in older women. This study informs the current scientific debate as to whether women aged 65 and above should be offered a catch-up HPV test if they never had an HPV test.

Risk of cervical intraepithelial neoplasia grade 2 or worse in women aged ≥ 69 referred to colposcopy due to an HPV-positive screening test. BMC Cancer 2023; 23:405. [PMID: 37142959 PMCID: PMC10161414 DOI: 10.1186/s12885-023-10888-1] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2022] [Accepted: 04/26/2023] [Indexed: 05/06/2023] Open
Abstract
BACKGROUND Cervical cancer incidence and mortality rates are high in older women in many developed countries, including Denmark. Therefore, Danish women aged 69 and older were invited for one additional human papilloma virus (HPV) based screening test in 2017. Here, we describe the clinical management and detection rate of cervical intraepithelial neoplasia grade 2 or worse (CIN2 +) in screen-positive women referred for colposcopy. METHODS We conducted an observational study in public gynecology departments in Central Denmark Region, Denmark. Women were eligible for enrolment if they were aged 69 + in 2017, HPV positive on a screening test taken between April 20th, 2017, and December 31st, 2017, and had been referred for direct colposcopy. Data on participants' characteristics, colposcopic findings, and histological outcomes were collected from medical records and the Danish Pathology Databank. We estimated the proportion of women with CIN2 + at the first colposcopy visit and at end of follow up including 95% confidence intervals (CIs). RESULTS A total of 191 women were included with a median age of 74 years (IQR: 71-78). Most women (74.9%) did not have a fully visible transformation zone at colposcopy. At the first visit 170 women (89.0%) had a histological sample collected, 34 of whom (20.0%, 95% CI 14.3-26.8%) had CIN2 + diagnosed, 19 had CIN3 + , and two had cervical cancer). During follow-up additional CIN2 + were detected resulting in a total of 42 women (24.4%, 95% CI: 18.2-31.5%) being diagnosed with CIN2 + , 25 with CIN3 + , and three with cervical cancer. When restricting to women with paired histologic results (i.e., biopsies and a loop electrosurgical excision procedure (LEEP) specimen), we found that CIN2 + was missed in 17.9% (95% CI 8.9-30.4%) of biopsies compared to the LEEP. CONCLUSION Our findings suggest a potential risk of underdiagnosis in older postmenopausal women referred to colposcopy. Future studies should explore potential risk-markers for discrimination of women at increased risk of CIN2 + from those at low risk, as this would reduce risk of underdiagnosis and overtreatment.

Abstract
INTRODUCTION To assess outcome of a one-time human papillomavirus (HPV)-screening in 2017 of Danish women aged 70+. MATERIAL AND METHODS Women born 1947 or before were personally invited to have a cell-sample collected by their general practitioner. Screening- and follow-up samples were analyzed in hospital laboratories in the five Danish regions and registered centrally. Follow-up procedures varied slightly across regions. Cervical intraepithelial neoplasia 2 (CIN2) was recommended treatment threshold. Data were retrieved from the Danish Quality Database for Cervical Cancer Screening. We calculated CIN2+ and CIN3+ detection rates per 1000 screened women, and number of biopsies and conizations per detected CIN2+ case. We tabulated annual number of incident cervical cancer cases in Denmark for the years 2009-2020. RESULTS In total, 359 763 women were invited of whom 108 585 (30% of invited) were screened; 4479 (4.1% of screened, and 4.3% of screened 70-74 years) tested HPV-positive; of whom 2419 (54% of HPV-positive) were recommended follow-up with colposcopy, biopsy and cervical sampling, and 2060 with cell-sample follow-up. In total, 2888 women had histology; of whom 1237 cone specimen and 1651 biopsy only. Out of 1000 screened women 11 (95% confidence interval [CI]: 11-12) had conization. In total, 579 women had CIN2+; 209 CIN2, 314 CIN3, and 56 cancer. Out of 1000 screened women five (95% CI: 5-6) had CIN2+. Detection rate of CIN2+ was highest in regions where conization was used as part of first-line follow-up. In 2009-2016, number of incident cervical cancers in women aged 70+ in Denmark fluctuated around 64; in 2017 it reached 83 cases; and by 2021 the number had decreased to 50. CONCLUSIONS The prevalence of high-risk HPV of 4.3% in women aged 70-74 is in agreement with data from Australia, and the detection of five CIN+2 cases per 1000 screened women is in agreement with data for 65-69 year old women in Norway. Data are thus starting to accumulate on primary HPV-screening of elderly women. The screening resulted in a prevalence peak in incident cervical cancers, and it will therefore take some years before the cancer preventive effect of the screening can be evaluated.

Abstract
OBJECTIVE To compare the proportion of cervical intraepithelial neoplasia grade 2 or higher (CIN2+) in cervical biopsies with that in large loop excision of the transformation zone (LLETZ) specimens in women aged ≥45 years with transformation zone type 3 (TZ3). DESIGN Multicentre cross-sectional study. SETTING Three colposcopy clinics in the Central Denmark Region. POPULATION Women aged ≥45 years referred to colposcopy as a result of a positive human papillomavirus (HPV) test and/or abnormal cytology and with TZ3 at colposcopy. METHODS Women had multiple biopsies taken and an LLETZ was performed. MAIN OUTCOME MEASURES Histologically confirmed CIN2+ in biopsies compared with that in LLETZ specimens. RESULTS Of 166 eligible women at colposcopy, 102 women with paired data from biopsies and LLETZ specimens were included for final analysis. The median age was 67.7 years (IQR 62.6-70.4 years), and most were postmenopausal (94.1%) and had undergone HPV-based screening (81.3%). The CIN2+ detection rate was significantly higher in LLETZ specimens than in biopsies (32.4% vs 14.7%, difference 17.7%, 95% CI 6.3-29.0%), resulting in more than half of CIN2+ cases being missed in biopsies (54.5%, 95% CI 36.4-71.9%). The overall agreement between biopsies and LLETZ was 82.4% (95% CI 73.6-89.2%). CONCLUSIONS CIN2+ detection is underestimated in women aged ≥45 years with TZ3 if detection relies on the results of biopsies alone. To reduce the risk of underdiagnosis and overtreatment, future studies should explore the use of new biomarkers for risk stratification to improve discrimination between women at increased risk of CIN2+ who need to undergo LLETZ and women who may undergo follow-up.

Abstract
The aim was to descriptively analyze the clinical characteristics, cytopathology, and outcomes of pregnant patients with high-risk human papillomavirus (HPV) infection. Clinical data of 151,516 female patients with high-risk HPV infection were retrospectively collected. Baseline data, cervical cytology results, histopathology, HPV types, delivery mode, and follow-up outcomes were recorded for descriptive analysis. A total of 157 patients were identified as positive for high-risk HPV. There were 32 (24.2%), 6 (4.5%), and 107 (81.1%) cases of HPV-16, HPV-18, and other types, respectively. Additionally, 12 patients showed combined infection with HPV-18 or HPV-16 and other types. Cytopathological examinations showed that the most common type was low-grade squamous intraepithelial lesion (LSIL; 104 cases, 78.8%), followed by high-grade squamous intraepithelial lesion (HSIL; 17 cases, 12.8%), atypical squamous cells of undetermined significance (10 cases, 9.6%), and cervical cancer (1 case, 0.7%). Thirty-seven patients underwent colposcopic biopsy, of whom 9 (24.3%) showed normal results, while 12 (32.4%) and 13 (35.1%) patients had LSIL and HSIL, respectively. χ2 tests demonstrated that different delivery modes did not show significant difference in patients' cervical cytopathology (p>0.05). However, therapeutic methods were statistically different among patients with different cytopathological types (p<0.05). Cervical alterations in pregnancy mostly go along with high-risk HPV infection. High-risk HPV infection in pregnancy with abnormal cervical cytology should be followed closely during the pregnancy and postpartum period.

Evidence of latent HPV infection in older Danish women with a previous history of cervical dysplasia. Acta Obstet Gynecol Scand 2022; 101:608-615.

Abstract
INTRODUCTION Understanding whether human papillomavirus (HPV) may establish latency in the uterine cervix is important. A better understanding of HPV natural history is useful for clinical counseling of women attending screening and to accurately inform health prevention strategies such as screening and HPV vaccination. We evaluated the extent of latent HPV infections in older women with a history of abnormal cytology. MATERIAL AND METHODS We conducted a cross-sectional study in Aarhus, Denmark, from March 2013 through April 2015. Women were enrolled if they underwent cervical amputation or total hysterectomy because of benign disease. Prior to surgery, women completed a questionnaire and a cervical smear was collected for HPV testing and morphological assessment. For evaluation of latency (i.e., no evidence of active HPV infection, but HPV detected in the tissue), we selected women with a history of abnormal cervical cytology or histology, as these women were considered at increased risk of harboring a latent infection. Cervical tissue underwent extensive HPV testing using the SPF10-DEIA-LipA25 assay. RESULTS Of 103 women enrolled, 26 were included in this analysis. Median age was 55 years (interquartile range [IQR] 52-65), and most women were postmenopausal and parous. The median number of sexual partners over the lifetime was six (IQR 3-10), and 85% reported no recent new sexual partner. Five women (19.2%) had evidence of active infection at the time of surgery, and 19 underwent latency evaluation. Of these, a latent infection was detected in 11 (57.9%), with HPV16 being the most prevalent type (50%). Nearly 80% (n = 14) of the 18 women with a history of previous low-grade or high-grade cytology with no treatment had an active or latent HPV infection, with latent infections predominating. HPV was detected in two of the six women with a history of high-grade cytology and subsequent excisional treatment, both as latent infections. CONCLUSIONS HPV can be detected in cervical tissue specimens without any evidence of an active HPV infection, indicative of a latent, immunologically controlled infection. Modeling studies should consider including a latent state in their model when estimating the appropriate age to stop screening and when evaluating the impact of HPV vaccination.

Cancer Med 2022; 11:224-237. [PMID: 34766466 PMCID: PMC8704149 DOI: 10.1002/cam4.4420] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/13/2021] [Revised: 10/14/2021] [Accepted: 10/24/2021] [Indexed: 01/10/2023] Open
Abstract
BACKGROUND In Denmark, human papillomavirus (HPV) testing has replaced cytology in primary cervical cancer screening for women aged 60-64; at this age, women are invited for the last (exit) screening test within the national organized program. AIM We investigated the adherence of these women to the recommended follow-up after a non-negative (positive or inadequate) HPV test and the overall resource use during that follow-up. MATERIALS & METHODS We included all 2926 women aged 60-64 years with nonnegative HPV screening tests between March 2012 and December 2016. All relevant follow-up tests and procedures were retrieved until the end of 2020 from the highly complete Danish administrative health registers, and the data were linked at the individual level. We determined the extent to which the adherence patterns followed the national recommendations for follow-up and estimated the total numbers of tests and diagnostic procedures utilized during the entire process. RESULTS In total, only 26% of women had follow-up in accordance with the recommendations; 4% had no follow-up, 46% had insufficient follow-up, and 24% had more follow-up than recommended. We estimated that 17% of women remained in follow-up for longer than 4 years. The average numbers of diagnostic tests and procedures used after positive HPV screening were higher than expected, even among women who had insufficient follow-up, that is, those who received less invasive procedures than recommended, or experienced delays in receiving those procedures. CONCLUSION To conclude, we found that the patterns of follow-up of women with nonnegative primary HPV screening tests at 60-64 often diverged from the recommendations. Addressing these inconsistencies in follow-up by providing evidence for optimal clinical management should help improve the quality of screening programs and secure an equal and reliable follow-up care service for all women.
