RESUMEN

OBJECTIVES: The integration of high-risk human papillomavirus (HPV) detection into cervical cancer screening in Poland aims to improve early detection, yet challenges in coverage and adherence persist. Innovative approaches, like sampling for HPV testing and cytology outside medical settings, have been proposed. This study assesses the feasibility and agreement of results between traditional and novel sampling methods. MATERIAL AND METHODS: A cohort of 50 women aged 25-74 underwent HPV DNA and liquid-based cytology sampling both in-office using standard method and outside the medical setting by trained personnel. Samples were analyzed for HPV DNA using Real-Time PCR and cytology according to the Bethesda System. RESULTS: Cytology and HPV DNA positivity rates showed substantial agreement between methods, with almost perfect agreement for high-risk HPV types. Visual assessment of the cervix was successfully conducted in all cases. Preliminary results suggest remote sampling for HPV DNA and cytology is a viable alternative to traditional methods, with the effectiveness in detecting HPV and cytological abnormalities comparable to this reported in literature, offering potential benefits for individuals with mobility limitations or logistical barriers to attending medical appointments. CONCLUSIONS: The study highlights the potential role of remote sampling for HPV DNA and cytology in enhancing cervical cancer screening accessibility and adherence. Implementation of such methods could improve coverage, particularly among underserved populations. Further research is needed to validate and optimize these approaches for broader clinical use.

RESUMEN

BACKGROUND: There is a need for additional longitudinal studies with the Aptima messenger RNA human papillomavirus test (AHPV) to support the safety of extended screening intervals. RNA-based extended interventional nucleic acid (REINA) provides relevant information on the clinical performance of AHPV. METHODS: This is a longitudinal prospective analysis of 1538 participants after AHPV and liquid-based cytology (LBC) co-test complemented with REINA interventional protocol with a second co-test 4 years after negative screening on 2000 women. Diagnostic accuracy and cumulative risks for CIN2+ up to 9 years were calculated for all test combinations. RESULTS: Sensitivity and specificity for CIN2+ were 96.9% and 88.0% for AHPV and 72.3% and 92.0% for LBC. Negative predictive value (NPV) and positive predictive value (PPV) of AHPV were 99.9% and 23.6%. The 5- and 9-year risks of AHPV-negative women were 0.4% and 1.0% (CIN2+) and 0.3% and 0.7% (CIN3+), a 73% and 64% lower risk than with negative LBC (p ≤ .002). REINA participants with an AHPV-positive result at second co-test after a negative AHPV in first round had a significantly lower 5-year risk of CIN2+ (11.1%) than AHPV-positive women with unknown HPV history (29.5%). CONCLUSIONS: Currently, this constitutes the longest European longitudinal study with AHPV testing in screening population. It reveals 99.9% NPV and a significant protective effect of a previous negative test 5 years after a new HPV infection. These findings support the safety of Aptima for screening intervals beyond 5 years. The risk of disease is lower 9 years after a negative AHPV test than 3 years after a negative LBC. High specificity and PPV of Aptima may benefit controlling overtreatment and colposcopy referrals.

RESUMEN

OBJECTIVE: This study aims to examine the relationship between human papillomavirus (HPV) testing attitudes and beliefs, knowledge, and vaccination attitudes. DESIGN: This study was a cross-sectional design. SAMPLE: This study was conducted between March 15, 2024, and June 2, 2024, through social media platforms such as Facebook, Instagram, Twitter, and Telegram, by sharing on forum pages, and involved 674 women who volunteered to participate. MEASUREMENTS: The research data were collected using the "health belief model scale regarding HPV infection and vaccination (HBMS-HPVV)" and the "HPV Testing Attitudes and Beliefs Scale (HTABS)," which were developed by the researchers through a literature review. RESULTS: The average age of the women participating in the study was 46.59 ± 11.15 years; 81.5% were married, 57.6% had no knowledge about cervical cancer, and 62.2% had no knowledge about the HPV vaccine, a protective vaccine against cervical cancer. The average scores for the subdimensions of severity, barriers, benefits, and susceptibility of the HBMS-HPVV were 3.19 ± 0.60, 2.96 ± 1.22, 2.29 ± 1.40, and 3.92 ± 0.49, respectively. The average scores for the subdimensions of personal barriers, social norms, confidence, and worries of the HTABS were 31.14 ± 19.27, 7.57 ± 4.47, 30.03 ± 7.18, and 11.91 ± 2.52, respectively. A statistically significant positive relationship was found between all HBMS-HPVV subdimensions and the HTABS subdimensions (p < 0.001). CONCLUSION: The study found that as the perceived severity increases, the perceived benefits, susceptibility, and confidence increase, while the perceived barriers, personal barriers, social norms, and worries decrease. Based on these results, it is recommended that women's health nurses provide education and seminars to raise awareness about cervical cancer, early screening and diagnosis programs, and the HPV vaccine.

RESUMEN

INTRODUCTION: In Denmark, where human papillomavirus (HPV) -based cervical cancer screening is being implemented, the aim of this pilot implementation study was to test a specific screening algorithm, assess follow-up examination attendance, and measure the proportion of precancer lesions found in relation to the number of women referred for colposcopy. MATERIAL AND METHODS: From May 2017 to December 2020, 36 417 women in the uptake area of the Department of Pathology, Vejle Hospital, Region of Southern Denmark, were included in the HPV group. Women positive for HPV16/18 irrespective of cytology and women positive for other high-risk HPV (hrHPV) types having concomitant abnormal cytology were referred directly to colposcopy. Women positive for other hrHPV types and normal cytology were referred to repeat screening after 12 months, and hrHPV negative to routine screening after three years. We obtained information on screening results and subsequent histological diagnosis from the Danish Pathology Databank through September 2022. RESULTS: 3.6% of the women were referred to colposcopy after primary screening, 5% to repeat screening after 12 months, and 91.4% back to routine screening. High follow-up rates were observed: 96% attended colposcopy after primary screening, with 91% attending colposcopy after repeat screening. CIN3+ was detected at colposcopy following the primary screening in 28.1% of HPV16/18-positive women and 18.2% of those positive for other hrHPV types with concomitant abnormal cytology. Of the women with other hrHPV and simultaneous ASCUS/LSIL, 8% had CIN3+. At the repeat screening, 43% had become hrHPV negative, 55% were persistently positive for other hrHPV, and 2% had turned positive for HPV16/18. At the colposcopy following repeat screening, 10.1% of the women positive for other hrHPV were diagnosed with CIN3+, in comparison with 11.1% of the HPV16/18-positive women. CONCLUSIONS: In this pilot implementation study, an algorithm for HPV-based screening was evaluated in a Danish setting. The results demonstrated high attendance at follow-up examinations and provided insights into the number of colposcopy referrals and the detection of CIN2 and CIN3+ cases. The results suggest that women testing positive for other hrHPV in combination with ASCUS/LSIL at primary screening could potentially be referred to repeat screening instead of an immediate colposcopy.

RESUMEN

Antenatal cervical screening aims to detect cervical intraepithelial neoplasms as precancerous lesions and invasive cervical cancer. Whether this screening is performed routinely during pregnancy varies depending on each country's screening participation rates, guidelines, and the risks to the pregnant woman. In some countries with the high rate of routinely implemented cervical screening among the target women, women are recommended to defer cervical screening intentionally to post-delivery, though having screening in consultation with physicians may be possible if routine screening overlaps. However, when cervical screening rate in fertile women is low and the incidence of cervical cancer is high, cervical screening during pregnancy may play an important role in the early detection of cervical cancer. Cervical screening using high-risk human papillomavirus (HPV) testing is accepted worldwide as a highly sensitive and objective test method, and it should replace traditional primary cervical cytology in the future. However, the benefits and disadvantages of using HPV testing in pregnant women is unclear because a false positive rate may be increased due to pregnant women being generally under an immunosuppressed condition.

RESUMEN

Cervical cancer is a significant public health concern, particularly in low- and middle-income countries where resources for prevention and treatment are limited. Routine screening, such as the Papanicolaou test (Pap smears) and human papillomavirus (HPV) testing, plays a crucial role in the early detection and prevention of cervical cancer. However, the participation rate in cervical cancer screening programs remains below optimal levels due to various factors. This study aimed to evaluate the reliability and acceptability of the HygeiaTouch Self Sampling Kit for Women in collecting vaginal samples for HPV typing, comparing the results with samples collected by physicians. The study included 1210 women aged 21-65 from three medical centers in Taiwan. The findings indicated that the self-sampling kit was as effective as physician-collected specimens in terms of obtaining valid samples and identifying HPV. The agreement between the two methods was 88%, with a κ value of 0.75. Furthermore, the study assessed the mechanical characteristics of the self-sampling applicator through tensile, bending, and torque tests, and determined that it was safe for intravaginal use. Additionally, the study evaluated the safety and satisfaction of self-sampling and found a low rate of adverse events (0.7%) and high levels of satisfaction (over 90%) among participants. Overall, we demonstrated that the HygeiaTouch Self Sampling Kit for Women is a reliable and acceptable device for HPV testing and cervical screening, providing a convenient, safe, and effective alternative for women.

RESUMEN

The U.S.-affiliated Pacific Islands (USAPI) have higher cervical cancer incidence and mortality rates and lower screening coverage compared with the United States. This is likely because of economic, geographical, health care delivery, and cultural barriers for women living in these resource-constrained, isolated regions. The most recent U.S. and World Health Organization cervical cancer screening guidelines recommended primary human papillomavirus (HPV) testing as one screening option or the preferred screening modality. Primary HPV screening-based strategies offer several advantages over current screening methods in the USAPI. However, adoption of this newer screening modality has been slow in the United States and not yet incorporated into USAPI screening programs. The U.S. Centers for Disease Control and Prevention and partners initiated the Pacific Against Cervical Cancer (PACe) project in 2019 to evaluate the feasibility, acceptability, and cost-effectiveness of primary HPV testing-based strategies in Guam and in Yap, Federated States of Micronesia. This report provides an overview of the PACe project and outlines the approaches we took in implementing primary HPV testing as a new cervical cancer screening strategy (including the option of self-sampling in Yap), encompassing four core components: (1) community engagement and education, (2) medical and laboratory capacity building, (3) health information and system improvement, and (4) modeling and cost-effectiveness analysis. The PACe project provides examples of systematic implementation and resource appropriate technologies to the USAPI, with broader implications for never screened and under-screened populations in the United States and Pacific as they face similar barriers to accessing cervical cancer screening services.

RESUMEN

INTRODUCTION: The rates of cervical cancer screening in Cameroon are unknown and HPV vaccination coverage for age-appropriate youths is reported at 5%. OBJECTIVES: To implement the mother-child approach to cervical cancer prevention (cervical screening by HPV testing for mothers and HPV vaccination for daughters) in Meskine, Far North, Cameroon. METHODS: After the sensitization of the Meskine-Maroua region using education and a press-release by the Minister of Public Health, a 5-day mother-child campaign took place at Meskine Baptist Hospital. The Ampfire HPV Testing was free for 500 women and vaccination was free for age-appropriate children through the EPI program. Nurses trained in cervical cancer education conducted group teaching sessions prior to having each woman retrieve a personal sample. Self-collected samples were analyzed for HPV the same day. All women with positive tests were assessed using VIA-VILI and treated as appropriate for precancers. RESULTS: 505 women were screened, and 92 children vaccinated (34 boys and 58 girls). Of those screened, 401 (79.4%) were aged 30-49 years old; 415 (82%) married; 348 (69%) no education. Of the HPV positive cases (101): 9 (5.9%) were HPV 16, 11 (10.1%) HPV 18, 74 (73%) HPV of 13 other types. Those who were both HPV and VIA-VILI positive were treated by thermal ablation (63%) or LEEP (25%). CONCLUSION: The mother-child approach is an excellent method to maximize primary and secondary prevention against cervical cancer.

RESUMEN

This study aimed to provide comprehensive clinical screening data for anal intraepithelial neoplasia (AIN). This study included 312 patients who underwent high-resolution anoscopy (HRA) examinations between January 1, 2020 and April 15, 2024. Clinical data, including demographic information, clinical history, cytology/high-risk human papilloma virus (hrHPV) results, and HRA records, were analyzed. The median age of all patients was 42 years (interquartile range: 33-52 years). Approximately 26.3% reported a history of VIN2/3+, 13.5% had a history of VaIN2/3+, 29.8% had a history of CIN2/3+, 44.6% had persistent cervical HPV16 infection, and 12.5% had immune suppression. Among the 312 patients, 14.4% were diagnosed with AIN2/3, 25.0% with AIN1 and 60.6% were normal. Anal cytological abnormalities were found in 41.3% of all patients, with a significantly higher rate in AIN2/3 patients than in ≤AIN1, 71.1% versus 36.3%, p < 0.001. The hrHPV positivity rate was 89.7%, with HPV16 being the most prevalent. The complete agreement rate for HRA impressions was 79.5%. Multi-variable analysis revealed immune suppression (odds ratio [OR]: 3.47, 95% confidence interval [CI]: 1.42-8.5) and VIN2/3+ (OR: 2.82, 95% CI: 1.27-6.28) were independent risk factors for AIN2/3. Abnormal cytology results (OR: 3.3, 95% CI: 1.52-7.17) and anal HPV16 infection (OR: 3.2, 95% CI: 1.26-8.12) demonstrated similar ORs for AIN2/3. Early screening for AIN2/3+ is crucial in Chinese women with lower genital tract precancerous and cancerous lesions, particularly in those with VIN2/3+ and immune suppression.

RESUMEN

BACKGROUND: The aim of the study was to evaluate the impact of urine-sample HPV (human papillomavirus) testing on the effectiveness of screening for cervical cancer. METHODS: The analysis was based on the results of a systematic review. Secondary studies were searched in the following medical databases: Medline, Embase, and the Cochrane Library. The results of the statistical tests presented in the article originate from research conducted by the authors of the included articles. RESULTS: From a total of 1869 citations, 5 studies were included in this review. Sensitivity and specificity for the detection of any HPV from first-void urine samples were 87% [95% CI: (0.74; 0.94)] and 89% [95% CI: (0.81; 0.93)], respectively. Moreover, participants in the analyzed studies had indicated that they felt comfortable with urine testing. CONCLUSIONS: The development of methods to detect HPV infection in first-void urine samples and the application of this sampling method in widely available screening tests could significantly increase patients' willingness to participate in testing.

RESUMEN

This research paper evaluates the efficacy of co-testing in precluding cervical cancer, with a particular focus on distinguishable outcomes of the human papillomavirus (HPV) vs. cytology tests. A retrospective review of 5948 patients, who tested positive for high-risk HPV but showed negative cytologic findings, revealed that 15.006% tested positive in subsequent screenings. A comparative analysis of various commercial HPV tests highlighted the precision of mRNA-based HPV testing by Aptima (Hologic) in reducing the likelihood of false-negative cytology. The paper challenges the conviction that a negative cytology alone suffices advocating for a condensed testing interval in instances of positive HPV outcomes, thereby facilitating earlier intervention and optimal preventive care. These findings unveil an exigency for reconsidering preventive strategies based on test outcomes.

RESUMEN

Cervical cancer seriously affects the health of women worldwide. Persistent infection of high-risk HPV (Human Papilloma Virus) can lead to cervical cancer. There is a great need for timely and efficient screening methods for cervical cancer. The current screening methods for cervical cancer are mainly based on cervical cytology and HPV testing. Cervical cytology is made of Pap smear and liquid-based cytology, while HPV testing is based on immunological and nucleic acid level detection methods. This review introduces cervical cancer screening methods based on cytology and human papillomavirus testing in detail. The advantages and limitations of the screening methods are also summarized and compared.

RESUMEN

The introduction of Human Papillomavirus (HPV) testing in cervical cancer screening enhanced the opportunity to introduce self-collection as an innovative approach to improve coverage rates. Validation and standardization of the pre-analytical and analytical procedures are crucial for the quality assurance of HPV tests on self-collected samples. This study evaluated the analytical performance and the stability of self-collected vaginal samples resuspended in 5 mL of two non-alcohol-based media, eNat® and MSwab® compared to a professionally collected cervical sample, resuspended in 20 mL ThinPrep®, for the detection of high-risk HPV (hrHPV). The impact of the suspension volumes on analytical performance was also evaluated (2 and 5 ml). A good analytical concordance in hrHPV detection in cervical and vaginal self-collected swabs suspended in 5 ml of both non-alcohol-based media was demonstrated (eNat®: 91.2 %, k = 0.821; MSwab®: 91.4 %; k = 0.798). A similar analytical performance was found for samples resuspended in 2 mL (eNat®: 92.9 %, k = 0.811; MSwab®: 92.9 %, k = 0.811) compared to cervical samples. Good nucleic acid stability was demonstrated for vaginal samples stored at 20-25 °C and 37 °C for up to 4 weeks. Results of this preliminary study support the introduction of these media for vaginal self-sampling-based prevention programs. Nevertheless, further research is necessary to evaluate clinical accuracy in larger settings.

RESUMEN

BACKGROUND: Cervical cancer screening remains an essential preventive tool worldwide. First line high-risk Human Papillomavirus (HrHPV) genotyping became gold standard for cervical cancer screening, and has been adopted by several countries, including Portugal. Herein, we aimed to assess the early outcomes of the regional Cervical Cancer Screening Program of Northern Portugal. METHODS: The analysis of a representative set of cases evaluated during a one-month period (January 2020), with adequate follow-up was performed. Descriptive analysis was performed. RESULTS: Overall, 7278 samples were received, of which 15.2% were HrHPV positive, most of these disclosing a negative result in subsequent liquid-based cytology. Nearly half of the HrHPV-positive women were referred to colposcopy. Within this group, HPV16/18+ cases depicted the higher frequency of high-grade squamous intraepithelial lesion (HSIL) or worse, compared with abnormal cytology or persistent HrHPV infection. Among women with non-HPV16/18 HrHPV infection and negative cytology, which are eligible for repeat sampling in one year, 65% were re-tested. Importantly, nearly half of these cleared HrHPV infection. Furthermore, referral to colposcopy due to HPV16/18 infection and/or abnormal cytology results were associated with > 40% risk for HSIL or worse lesion. CONCLUSIONS: Our study confirmed the reliability and effectiveness of first line HrHPV genotyping in the Cervical Cancer Screening Program of Northern Portugal. Nonetheless, it also raised concerns about excessive referral to colposcopy, with the inherent human and financial costs. Thus, further improvement and optimization are key to ensure the sustainability of the program.

RESUMEN

OBJECTIVE: This study aims to evaluate the feasibility and applicability of an online cervical cancer screening program using a website as the public platform and self-collected HPV testing as the primary screening method. METHODS: A website (mcareu.com) was developed to facilitate the online cervical cancer screening program by Peking University Shenzhen Hospital (PUSH). Women in Shenzhen could register for participation on the website by providing essential demographic data. Sampling kits and specimens were delivered through regular logistics. Eligible women collected vaginal samples by themselves using the provided kits and in referring of the graphic guidance. The specimens were tested for HPV at PUSH or a reference lab, and the results were accessible on the website through participants' personal accounts. Participants who tested positive for high-risk HPV were scheduled for colposcopy and biopsies. The demographic and social background data of the eligible participants were analyzed to evaluate the feasibility and applicability of the online screening approach. RESULTS: A total of 1712 applicants registered for participation, with 99.9% (1710/1712) completing registration with full data. The analysis included 1560 applicants aged 30-59, with an average age of 41.1 (± 7.6) years. Among them, 83.3% (1299/1560) provided self-collected samples for testing. Age-group analysis revealed an overall sample provision rate (SPR) exceeded 80% in all age groups. A significant difference in SPR was observed only between the 30-34 and 45-49 age groups (p < 0.05), while no significant differences were found among other age groups. 99.7% of the samples were tested qualified, and there was no significant difference in sampling failure rate among age groups. Analysis of demographic and social elements showed no significant impact on the rates of sample provision among groups in most of the social elements but the medical insurance and the monthly family-incomes. CONCLUSION: The findings demonstrate that online cervical cancer screening is reliable for self-registration, self-sampling, and self-ordering for specimen transportation. It is suitable for women of all ages needing to be screened, irrespective of social elements, and effectively facilitates screening for women with limited access to medical resources. Therefore, online screening holds promise as an effective approach to increase screening coverage.

RESUMEN

BACKGROUND: The 2020 American Cancer Society (ACS) guidelines are the most recent national guidelines for cervical cancer screening. These guidelines propose two major changes from current practice: initiating screening at age 25 years and using primary human papillomavirus (HPV) testing. Adoption of guidelines often occurs slowly, and therefore understanding clinician attitudes is important to facilitate practice change. METHODS: Interviews with a national sample of clinicians who perform cervical cancer screening in a variety of settings explored attitudes toward the two major changes from the 2020 ACS cervical cancer screening guidelines. Clinicians participated in 30- to 60-min interviews exploring their attitudes toward various aspects of cervical cancer screening. Qualitative analysis was performed. RESULTS: Seventy clinicians participated from across the United States. Few respondents were initiating screening at age 25 years, and none were using primary HPV testing. However, over half would be willing to adopt these practices if supported by scientific evidence and recommended by professional medical organizations. Barriers to adoption included the lack of endorsement by professional societies, lack of laboratory availability and insurance coverage, limited autonomy within large health care systems, and concerns related to missed disease. CONCLUSIONS: Few clinicians have adopted screening initiation or primary HPV testing, as recommended by the 2020 ACS guidelines, but over half were open to adopting these changes. Implementation may be facilitated via professional organization endorsement, clinician education, and laboratory, health care system, and insurance support. PLAIN LANGUAGE SUMMARY: In 2020, the American Cancer Society (ACS) released updated guidelines for cervical cancer screening. The main changes to current practices were to initiate screening at age 25 years instead of age 21 years and to screen using primary human papillomavirus (HPV) testing rather than cytology alone or in combination with HPV testing. We performed in-depth interviews with 70 obstetrics and gynecology, family medicine, and internal medicine physicians and advanced practice providers about their attitudes toward these guidelines. Few clinicians are following the 2020 ACS guidelines, but over half were open to changing practice if the changes were supported by evidence and recommended by professional medical organizations. Barriers to adoption included the lack of endorsement by professional medical organizations, logistical issues, and concerns about missed disease.

RESUMEN

BACKGROUND: Some high-grade cervical lesions and cervical cancers (HSIL+) test negative for human papillomavirus (HPV). The HPV-negative fraction varies between 0.03 % and 15 % between different laboratories. Monitoring and extended re-analysis of HPV-negative HSIL+ could thus be helpful to monitor performance of HPV testing services. We aimed to a) provide a real-life example of a quality assurance (QA) program based on re-analysis of HPV-negative HSIL+ and b) develop international guidance for QA of HPV testing services based on standardized identification of apparently HPV-negative HSIL+ and extended re-analysis, either by the primary laboratory or by a national HPV reference laboratory (NRL). METHODS: There were 116 initially HPV-negative cervical specimens (31 histopathology specimens and 85 liquid-based cytology samples) sent to the Swedish HPV Reference Laboratory for re-testing. Based on the results, an international QA guidance was developed through an iterative consensus process. RESULT: Standard PCR testing detected HPV in 55.2 % (64/116) of initially "HPV-negative" samples. Whole genome sequencing of PCR-negative samples identified HPV in an additional 7 samples (overall 61.2 % HPV positivity). Reasons for failure to detect HPV in an HSIL+ lesion are listed and guidance to identify cases for extended re-testing, including which information should be included when referring samples to an NRL are presented. CONCLUSION: Monitoring the proportion of and reasons for failure to detect HPV in HSIL+ will help support high performance and quality improvement of HPV testing services. We encourage implementation of QA strategies based on re-analysis of "HPV negative" HSIL+ samples.

RESUMEN

The positive clinical threshold of human papillomavirus (HPV) tests validated for primary cervical cancer screening (CCS) is designed to offer an optimal balance between clinical sensitivity and specificity. However, there may be a gap between the analytical sensitivity of the test and the positive clinical threshold, referred to here as the "gray-zone." This study aims to determine the prevalence and significance of HPV results obtained in the gray-zone in routine practice. Cervical samples obtained in our institution for CCS over a 22-month-period were tested with the Alinity m HR-HPV Assay (Abbott). Clinical and biological data, including cytological results and patients' HPV history were collected. Of the 6101 samples collected, 1.7% had an HPV result in the gray-zone (102 patients). The proportion of gray-zone results varied according to HPV genotype, reaching 11.8% of samples with detectable HPV DNA in the case of HPV31/33/52/58 genotypes. Reflex cytologies showed no abnormalities or Atypical Squamous Cells of Undetermined Significance results in 74.6% and 17.9% of cases, respectively. A previous or subsequent HPV-positive result with a (possibly) identical genotype was observed in 58% and 38% of cases, respectively. Two women with a history of persistent HPV detection had a CIN2+ lesion 1 year after the gray-zone result. In conclusion, the proportion of HPV results in the gray-zone varies according to genotype. No cytological abnormality is observed in the majority of cases, but a few rare patients with a history of persistent HPV infection should be closely monitored even if the HPV result is transiently located in the gray-zone.

RESUMEN

High-risk human papillomavirus (hrHPV) is the cause of virtually all cervical cancers, most vaginal and anal cancers, and some vulvar cancer cases. With HPV testing becoming the primary screening method for cervical cancer, understanding the link between cervical hrHPV infection and the risk of other anogenital cancers is crucial. We assessed the risk of vulvar, vaginal and anal cancer and precancer (VIN2+, VaIN2+ and AIN2+) in a prospective cohort study including 455,349 women who underwent cervical hrHPV testing in Denmark from 2005 to 2020. We employed Cox proportional hazard models, adjusting for age, calendar year and HPV vaccination status, and estimated hazard ratios (HRs) and 95% confidence intervals (CI). We used the Aalen Johansen estimator to calculate the absolute risks of VIN2+, VaIN2+ and AIN2+. In total, 15% of the women were hrHPV positive at baseline. A positive cervical hrHPV test was associated with increased incidence of vulvar, vaginal and anal squamous cell carcinoma (SCC). Five-year risk estimates of VIN2+, VaIN2+ and AIN2+ among hrHPV-positive women (0.45%, 0.14% and 0.12%) were higher than among hrHPV-negative women (0.14%, 0.01% and 0.05%). Particularly high risk was observed among the hrHPV-positive women of the oldest age, with a history of anogenital precancer and those not HPV vaccinated. In conclusion, our study confirms the association between cervical hrHPV infection and non-cervical anogenital precancers and cancers. Currently, no established risk threshold or guidelines for follow-up. As HPV testing becomes the primary method for cervical cancer screening, future data will help define high-risk groups and acceptable risk thresholds.

RESUMEN

Cervical cancer, primarily caused by high-risk human papillomavirus (HR-HPV) types 16 and 18, is a major global health concern. Persistent HR-HPV infection can progress from reversible precancerous lesions to invasive cervical cancer, which is driven by the oncogenic activity of human papillomavirus (HPV) genes, particularly E6 and E7. Traditional screening methods, including cytology and HPV testing, have limited sensitivity and specificity. This review explores the application of p16/Ki-67 dual-staining cytology for cervical cancer screening. This advanced immunocytochemical method allows for simultaneously detecting p16 and Ki-67 proteins within cervical epithelial cells, offering a more specific approach for triaging HPV-positive women. Dual staining and traditional methods are compared, demonstrating their high sensitivity and negative predictive value but low specificity. The increased sensitivity of dual staining results in higher detection rates of CIN2+ lesions, which is crucial for preventing cervical cancer progression. However, its low specificity may lead to increased false-positive results and unnecessary biopsies. The implications of integrating dual staining into contemporary screening strategies, particularly considering the evolving landscape of HPV vaccination and changes in HPV genotype prevalence, are also discussed. New guidelines and further research are necessary to elucidate the long-term effects of integrating dual staining into screening protocols.
