Clinical evaluation of primary human papillomavirus (HPV) testing with extended HPV genotyping triage for cervical cancer screening: A pooled analysis of individual patient data from nine population-based cervical cancer screening studies from China. Cancer Med 2024; 13:e7316. [PMID: 38828559 PMCID: PMC11145129 DOI: 10.1002/cam4.7316] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/03/2023] [Revised: 04/24/2024] [Accepted: 05/07/2024] [Indexed: 06/05/2024] Open
Abstract
OBJECTIVE To assess the clinical values of extended human papillomavirus (HPV) genotyping in triage of high-risk HPV-positive women, focusing on the trade-off between cervical precancer detections and colposcopy referrals. METHODS A bivariate random-effects model was used to estimate the diagnostic accuracy of primary HPV screening with following triage strategies to detect cervical precancers: (i) partial genotyping for HPV16/18 combined with cytological testing at atypical squamous cells of undetermined significance threshold (used as the comparator), (ii) genotyping for HPV16/18/58/52, (iii) genotyping for HPV16/18/58/52/33, (iv) genotyping for HPV16/18/58/33/31, (v) genotyping for HPV16/18/58/52/33/31, and (vi) genotyping for HPV16/18/58/52/33/31/39/51. Internal risk benchmarks for clinical management were used to evaluate the risk stratification of each triage strategy. RESULTS A total of 16,982 women (mean age 46.1 years, range 17-69) were included in this analysis. For CIN3+ detection, triage with HPV16/18/58/33/31 genotyping achieved lower positivity (6.85% vs. 7.35%, p = 0.001), while maintaining similar sensitivity (91.35% vs. 96.42%, p = 0.32) and specificity (94.09% vs. 93.67%, p = 0.56) compared with the comparator strategy. Similar patterns were observed for CIN2+ detection. Women with a positive HPV16/18/58/33/31 genotyping test had high enough risk for CIN3+ for colposcopy referral, while the risk for women with a negative test was below the 1-year return decision threshold according to internal benchmarks. CONCLUSIONS Our findings suggested extended HPV genotyping is of potential to be used as a triage technique integrated into HPV-based cervical cancer screening, leading to reduced need for colposcopy referral while maintaining similar disease detection and efficient risk stratification.

High-Risk Genotypes of Human Papillomavirus at Diverse Anogenital Sites among Chinese Women: Infection Features and Potential Correlation with Cervical Intraepithelial Neoplasia. Cancers (Basel) 2024; 16:2107. [PMID: 38893229 PMCID: PMC11172096 DOI: 10.3390/cancers16112107] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/16/2024] [Revised: 05/26/2024] [Accepted: 05/29/2024] [Indexed: 06/21/2024] Open
Abstract
BACKGROUND Both cervical cancer and cervical intraepithelial neoplasia (CIN) are associated with human papillomavirus (HPV) infection at different anogenital sites, but the infection features of high-risk (HR) HPVs at these sites and their association with cervical lesions have not been well characterized. Given the limitation of cervical HPV 16/18 test in screening patients with high-grade CIN (CIN 2+), studies on whether non-16/18 HR-HPV subtype(s) have potential as additional indicator(s) to improve CIN 2+ screening are needed. METHODS The infection of 15 HR-HPVs in vulva, anus, vagina, and cervix of 499 Chinese women was analyzed, and CIN lesion-associated HR-HPV subtypes were revealed. RESULTS In addition to the well-known cervical-cancer-associated HPV 16, 52, and 58, HPV 51, 53, and 56 were also identified as high-frequency detected subtypes prevalently and consistently present at the anogenital sites studied, preferentially in multi-infection patterns. HPV 16, 52, 58, 56, and 53 were the top five prevalent subtypes in patients with CIN 2+. In addition, we found that cervical HPV 33/35/52/53/56/58 co-testing with HPV 16/18 might improve CIN 2+ screening performance. CONCLUSION This study provided a new insight into HR-HPV screening strategy based on different subtype combinations, which might be used in risk stratification clinically.

[PMID: 37810963 PMCID: PMC10560038 DOI: 10.3389/fonc.2023.1243888] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2023] [Accepted: 08/28/2023] [Indexed: 10/10/2023] Open
Abstract
We review developments in molecular triaging options for women who test positive for high-risk human papillomavirus (hrHPV) on self-collected samples in the context of cervical cancer elimination. The World Health Organization (WHO) recommends hrHPV screening as the primary test for cervical screening due to its high sensitivity compared to other screening tests. However, when hrHPV testing is used alone for treatment decisions, a proportion of women of childbearing age receive unnecessary treatments. This provides the incentive to optimize screening regimes to minimize the risk of overtreatment in women of reproductive age. Molecular biomarkers can potentially enhance the accuracy and efficiency of screening and triage. HrHPV testing is currently the only screening test that allows triage with molecular methods using the same sample. Additionally, offering self-collected hrHPV tests to women has been reported to increase screening coverage. This creates an opportunity to focus health resources on linking screen-positive women to diagnosis and treatment. Adding an additional test to the screening algorithm (a triage test) may improve the test's positive predictive value (PPV) and offer a better balance of benefits and risks for women. Conventional triage methods like cytology and visual inspection with acetic acid (VIA) cannot be performed on self-collected samples and require additional clinic visits and subjective interpretations. Molecular triaging using methods like partial and extended genotyping, methylation tests, detection of E6/E7 proteins, and hrHPV viral load in the same sample as the hrHPV test may improve the prediction of cervical intraepithelial neoplasia grade 2 or worse (CIN2+) and invasive cancer, offering more precise, efficient, and cost-effective screening regimes. More research is needed to determine if self-collected samples are effective and cost-efficient for diverse populations and in comparison to other triage methods. The implementation of molecular triaging could improve screening accuracy and reduce the need for multiple clinical visits. These important factors play a crucial role in achieving the global goal of eliminating cervical cancer as a public health problem.

Human papillomavirus testing on self-collected samples to detect high-grade cervical lesions in rural Bhutan: The REACH-Bhutan study. Cancer Med 2023; 12:11828-11837. [PMID: 36999740 PMCID: PMC10619475 DOI: 10.1002/cam4.5851] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/29/2022] [Revised: 01/09/2023] [Accepted: 03/13/2023] [Indexed: 04/01/2023] Open
Abstract
BACKGROUND "REACH-Bhutan" aimed to evaluate the feasibility and clinical performance of a community-based screening program for cervical cancer in rural Bhutan using self-collected samples for high-risk human papillomavirus (HR-HPV) testing. METHODS In April/May 2016, 2590 women aged 30-60 years were screened across rural Bhutan by providing a self-collected sample for careHPV testing. All careHPV-positive women, plus a random sample of careHPV-negative women, were recalled for colposcopy and biopsy. Self-samples also underwent GP5+/6+ polymerase chain reaction (PCR)-based HR-HPV DNA detection and genotyping. Cross-sectional screening indices were estimated against histological high-grade squamous intraepithelial lesions or worse (hHSIL+), including imputation of hHSIL+ in women without colposcopy. RESULTS HR-HPV positivity was 10.2% by careHPV and 14.8% by GP5+/6+ PCR. Twenty-two cases of hHSIL+ were histologically diagnosed, including one invasive cancer; an additional 7 hHSIL+ were imputed in women without colposcopy. HR-HPV testing by GP5+/6+ showed higher sensitivity for hHSIL+ (89.7%, 95% CI 72.6-97.8) than careHPV (75.9%, 95% CI 56.5-89.7). Negative predictive value was also slightly higher for GP5+/6+ (99.9%, 95% CI 99.6-100) than careHPV (99.7%, 95% CI 99.4-99.9). Specificity, however, was lower for GP5+/6+ (86.1%, 95% CI 84.6-87.4) than careHPV (90.6%, 95% CI 89.4-91.7), as was positive predictive value (6.9%, 95% CI 4.5-9.9 vs. 8.5%, 95% CI 5.4-12.6). Of 377 HR-HPV-positive women by GP5+/6+, 173 (45.9%) were careHPV-positive, including 54.7% HPV16-positive and 30.2% HPV18-positive women. CONCLUSIONS The final REACH-Bhutan results show that screening for cervical cancer with self-collection of samples and HR-HPV testing, in addition to our previous report of achieving high participation, can also perform well to detect women with hHSIL+.

Cost-effectiveness of the screen-and-treat strategies using HPV test linked to thermal ablation for cervical cancer prevention in China: a modeling study. BMC Med 2023; 21:149. [PMID: 37069602 PMCID: PMC10111823 DOI: 10.1186/s12916-023-02840-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/17/2022] [Accepted: 03/20/2023] [Indexed: 04/19/2023] Open
Abstract
BACKGROUND Self-sampling HPV test and thermal ablation are effective tools to increase screening coverage and treatment compliance for accelerating cervical cancer elimination. We assessed the cost-effectiveness of their combined strategies to inform accessible, affordable, and acceptable cervical cancer prevention strategies. METHODS We developed a hybrid model to evaluate costs, health outcomes, and incremental cost-effectiveness ratios (ICER) of six screen-and-treat strategies combining HPV testing (self-sampling or physician-sampling), triage modalities (HPV genotyping, colposcopy or none) and thermal ablation, from a societal perspective. A designated initial cohort of 100,000 females born in 2015 was considered. Strategies with an ICER less than the Chinese gross domestic product (GDP) per capita ($10,350) were considered highly cost-effective. RESULTS Compared with current strategies in China (physician-HPV with genotype or cytology triage), all screen-and-treat strategies are cost-effective and self-HPV without triage is optimal with the most incremental quality-adjusted life-years (QALYs) gained (220 to 440) in rural and urban China. Each screen-and-treat strategy based on self-collected samples is cost-saving compared with current strategies (-$818,430 to -$3540) whereas more costs are incurred using physician-collected samples compared with current physician-HPV with genotype triage (+$20,840 to +$182,840). For screen-and-treat strategies without triage, more costs (+$9404 to +$380,217) would be invested in the screening and treatment of precancerous lesions rather than the cancer treatment compared with the current screening strategies. Notably, however, more than 81.6% of HPV-positive women would be overtreated. If triaged with HPV 7 types or HPV16/18 genotypes, 79.1% or 67.2% (respectively) of HPV-positive women would be overtreated with fewer cancer cases avoided (19 cases or 69 cases). CONCLUSIONS Screen-and-treat strategy using self-sampling HPV test linked to thermal ablation could be the most cost-effective for cervical cancer prevention in China. Additional triage with quality-assured performance could reduce overtreatment and remains highly cost-effective compared with current strategies.

Experiences with thermal ablation for cervical precancer treatment after self-collection HPV-based screening in the ASPIRE Mayuge randomized trial. Int J Cancer 2023; 152:1630-1639.

Abstract
Cervical cancer remains a significant public health burden in low-resourced countries. Thus, the WHO prioritized cervix screening, and recently recommended thermal ablation treatment for cervical precancer. However, there is limited information on side effects during treatment and recovery, and acceptability among those treated. The ASPIRE Mayuge trial recruited women to participate in self-collection cervix screening between 2019 and 2020 (N = 2019). Screen-positive women (N = 531, 26.3%) were referred for visual inspection with acetic acid and thermal ablation treatment, per Uganda Ministry of Health recommendations; 71.2% of those referred attended follow-up. Six months post-screening, a subset of trial participants were recontacted. Those who received thermal ablation completed a survey assessing side effects during and after the procedure, and willingness to recommend the treatment to others. We summarized the results to describe the side effects and acceptability of thermal ablation treatment. Of 2019 participants, 349 (17%) received thermal ablation. A subset of 135 completed the follow-up survey, where 90% reported pain during treatment; however, intensity and duration were low. Over a third of women reported problems with recovery for reasons including pain, discharge and bleeding. Regardless, 98% reported they would recommend the treatment to others. The use of thermal ablation to treat cervical precancer appears to be highly acceptable in this population. While many women reported side effects during the procedure and recovery, the majority said they would recommend the treatment to others. However, given the substantial proportion who reported problems with recovery, efforts should be made to provide additional resources to women after receiving thermal ablation treatment for cervical precancer.

Abstract
OBJECTIVE This study aims to compare the results of cervical cancer screening in Shanghai General Hospital before and after the COVID-19 epidemic, and analyze the current status and related influencing factors of precervical cancer screening in our hospital under the COVID-19 pandemic. METHODS The data of 13,748 women of cervical precancer screening with HPV in Shanghai General Hospital were selected.The data included human papillomavirus (HPV), thin-layer liquid-based cytology test (TCT), colposcopy and cervical biopsy, and pathological diagnosis results after trachelectomy in 2019 and 2020, and were analyzed and compared. RESULTS The detection rates of precancerous lesions and cervical cancer were 2.9061/10,000 and 29.26/10,000 respectively. There was a significant difference in the rate of comparison (χ2 = 30.361, P = 0.000; χ2 = 7.682, P = 0.006);(2) Missing detection rate: In 2020, other positive subtypes other than HPV 16 and 18 who need TCT, the colposcopy, and the histopathological examination missing detection rate were higher than those in 2019 (P < 0.05);(3) Abnormal rate of examination: the abnormal rate of HPV, TCT, and histopathology in 2020 was higher than those in 2019 (P < 0.05);(4) Histopathological analysis: The detection rate of high-grade lesions and invasive cancer in 2020 was higher than those in 2019, and the detection rate of low-grade lesions was lower than that in 2019 (P < 0.05); Conclusion: Health authorities should formulate intervention measures to cope with the safe and timely implementation of cervical cancer screening and subsequent follow-up management during public health emergency.

Abstract
PURPOSE Although cervical cancer is a disease of inequity, it can be eliminated as a public health problem through vaccination, screening, and treatment. Human papillomavirus vaginal self-collection cervical screening is a high-performance test that can increase reach of screening. This review describes the different contexts and models of care used to pilot or implement self-collection within the Asia-Pacific, measures the extent that implementation outcome measures are reported and, where available, summarizes key implementation findings. METHODS A scoping review was conducted by searching five databases of the peer-reviewed literature on June 20, 2022. Two researchers assessed eligibility and extracted data independently to the model of care used and the Conceptual Framework for Implementation Outcomes. A mixed-method consolidation of findings (quantitative: count and frequencies; qualitative: content analysis) was undertaken to narratively report findings. RESULTS Fifty-seven articles, comprising 50 unique studies from 11 countries and two special autonomous regions, were included; 82% were conducted in trials. The implementation of self-collection was conducted in low- (2%), lower-middle- (32%), upper-middle- (32%), and high-income (35%) settings, with 10 different delivery models used; 80% delivered through practitioner-supported models with diversity in how samples were processed, and treatment was offered. Acceptability (73%) and appropriateness (64%) measures were most reported, followed by adoption (57%), feasibility (48%), and fidelity (38%). Only 7% of articles reported implementation cost or penetration measures. No articles reported sustainability measures. CONCLUSION The literature confirms that self-collection cervical screening has been implemented within the Asia-Pacific region, with evidence demonstrating that it is acceptable and appropriate from the user's perspective. Well-designed, high-quality implementation trials and real-world evaluations of self-collection that report the breadth of implementation outcomes can support the progression toward the elimination of cervical cancer.

Abstract
PURPOSE This ongoing trial is comparing the efficacy and safety of three ablation treatments for cervical intraepithelial neoplasia grade 2 or higher. Here, we present early data regarding pain, side effects, and acceptability of CO2 gas-based cryotherapy (CO2), nongas cryotherapy, and thermal ablation (TA). Efficacy results are expected to become available in late 2023. MATERIALS AND METHODS This noninferiority randomized trial is taking place in El Salvador, China, and Colombia. Patients are 1,152 eligible women with biopsy-confirmed cervical intraepithelial neoplasia grade 2 or higher who will receive one of three ablation treatments. Pain is measured before, during, and after treatment with a visual analog scale (1-10). Side effects and acceptability are assessed at 6 weeks. RESULTS To date, 1,024 of 1,152 (89%) women were randomly assigned to treatment. The median pain level was higher during TA (4, IQR = 4) than CO2 (2, IQR = 4) or nongas cryotherapy (2, IQR = 4) (P < .01, range: 0-10). The most common post-treatment symptom was watery discharge, reported by 97.9% of women, and it lasted longer in the CO2 group than the other two treatments (in days, median [IQR]: CO2 = 20[20], nongas cryotherapy = 15[10], TA = 18[15], P < .01). Bleeding was reported more frequently in women treated with TA (27.6%) than CO2 (17.5) or nongas cryotherapy (18.7%) (P < .01). The majority of patients reported being very satisfied with the treatment they received at 6 weeks (91%) and again at 12 months post-treatment (97%). CONCLUSION Despite differences in pain and side effects across ablation treatments, all were safe and highly acceptable to patients. In addition to efficacy, considerations such as cost and portability may be more significant in choosing a treatment method.

Front Microbiol 2022; 13:1040285. [PMID: 36439807 PMCID: PMC9691997 DOI: 10.3389/fmicb.2022.1040285] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2022] [Accepted: 10/21/2022] [Indexed: 08/30/2023] Open
Abstract
BACKGROUND This study aimed to evaluate the performance of two different principles of HPV testing in primary cervical cancer screening and ASC-US triage in rural areas. METHODS 3,328 and 3,913 women were enrolled in Shanxi, China in 2017 and 2018, respectively, and screened using liquid-based cytology and different HPV tests with a 4-year follow-up. Different screening methods commonly used in clinical practice were evaluated. RESULTS In the HPV PCR test cohort, the prevalence of HPV infection was 14.90%. A total of 38 cases of CIN2+ were identified at baseline, 2 of which were in the HPV-negative cohort and the rest in the HPV-positive cohort (2 = 186.85, p < 0.001). Fifty-three cases of CIN2+ were accumulated over 4 years. The HPV infection rate in the HPV DNA chip test cohort was 21.10%. A total of 26 CIN2+ cases were identified at baseline, all in the HPV-positive population (2 = 92.96, p < 0.001). 54 CIN2+ cases were cumulative over 4 years. At 4-year follow-up, HPV-negative results were significantly more protective against cervical intraepithelial neoplasia grade 2 or worse (CIN2+) than normal cytologic results at baseline. HPV screening was more sensitive and specific than cytologic screening (using ASC-US as the threshold) and performed better on the HPV DNA microarray test. In addition, compared with HPV 16/18 testing, sensitivity increases and specificity decreases when using HPV testing for cytologic ASC-US triage, regardless of which HPV test is used. CONCLUSION In the rural areas where we implemented the study, HPV tests performed well for screening than LBC and HPV DNA chip testing performed better than HPV PCR testing in the screening cohort. Optimal screening was achieved technically when used in combination with LBC for ASC-US population triage, without thinking the feasibility for resource availability.

Abstract
BACKGROUND The objective of this study was to explore women's experiences of a screen-and-treat approach with ablative therapy (referred to by the Spanish acronym TVT-TA) as a method of treatment following a positive HPV test in Iquitos, Peru. METHODS A total of 111 in-depth interviews were conducted with 47 HPV positive women who attended the TVT-TA procedure at a primary-level healthcare facility. Interviews were conducted immediately before, immediately after, and six-weeks after TVT-TA. RESULTS Most interviewed women reported experiencing moderate pain during ablative therapy and minimal pain immediately after and six weeks after ablative therapy. Women also stated that the pain was less intense than they had expected. The most common physical after-effects of treatment were bleeding and vaginal odor. Women experienced oscillating emotions with fear upon receiving a positive HPV result, calming after hearing about ablative therapy treatment, worry about pain from the treatment itself, relaxation with counseling about the procedure, and relief following treatment. CONCLUSIONS Nearly all participants emphasized that they were pleased with the TVT-TA process even if they had experienced pain during TVT-TA, recommended that TVT-TA be expanded and available to more women, and stated that TVT-TA was faster and easier than expected. This study found that TVT-TA is a feasible and acceptable means of treating HPV according to the women receiving the treatment.

Triage performance and predictive value of the human gene methylation panel among women positive on self-collected HPV test: Results from a prospective cohort study. Int J Cancer 2022; 151:878-887. [PMID: 35460075 DOI: 10.1002/ijc.34041] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/10/2021] [Revised: 03/15/2022] [Accepted: 04/08/2022] [Indexed: 11/11/2022]
Abstract
Triaging of women positive for high-risk human papillomavirus (hrHPV) on self-collected samples requires a molecular reflex test to avoid recall for cytology or visual tests. We assessed triage performance and predictive value of human gene methylation panel (ZNF671/ASTN1/ITGA4/RXFP3/SOX17/DLX1) alone and with combination of HPV16/18 genotyping in a longitudinal screening study. Out of 9526 women at baseline, 1758 women positive for hrHPV on self-collected samples followed up yearly were included in the current analysis. Satisfactory risk stratification to detect cervical intraepithelial neoplasia grade 2 or worse (CIN2+) was demonstrated by the methylation panel with an odds ratio (OR) of 11.3 among methylation-positive women compared to methylation-negative counterparts. Triaging with methylation panel reduced colposcopy referral rate by 67.2% with sensitivity and specificity of 83.0% and 69.9% to detect CIN2+. The corresponding values for the combining methylation and HPV 16/18 were 96.6% and 58.3%. The cumulative 3-year incident CIN2+ risk was 6.8% (95% CI: 4.9%-8.6%) for hrHPV positive women, which was reduced to 4.5% (95% CI: 2.7%-6.3%) and 2.9% (95% CI: 1.2%-4.5%) for women negative on methylation triaging alone and negative on the combined strategy. The corresponding risk for women positive for both methylation and HPV 16/18 reached 33.7% (95% CI: 19.0%-45.8%). Our study demonstrated the satisfactory triage performance and predictive value of the methylation panel, especially in combination with HPV 16/18 genotyping. The substantially lower risk of CIN2+ among the triage negative women over the next 3 years suggests that the interval for repeat HPV test can be safely extended to at least 2 years.

Abstract
Objective Understanding the side effects and acceptability of thermal ablation (TA) is necessary before large-scale application in screen-and-treat programmes can be justified in low-income and middle-income countries (LMICs). Design Articles were selected for inclusion by two independent reviewers. Risk of bias was assessed using the Downs and Black’s criteria. Summary data were extracted, and authors contacted for data when necessary. Proportions of interest and 95% CIs were estimated using a random effects model. Subgroup analysis was performed based on place of treatment and timing of post-treatment follow-up. Heterogeneity was estimated using the I2. Eligibility criteria Studies that reported one or more side effects or patient acceptability measures after treatment of the cervix using TA in women living in LMICs who completed a cervical cancer screening test. Included articles were clinical trials or observational studies available in English and published before 18 December 2020. Information sources Ovid MEDLINE, EMBASE, CINAHL, CAB Global Health and WHO Global Index Medicus were searched for this systematic review and meta-synthesis. Results A total of 1590 abstracts were screened, 84 full text papers reviewed and 15 papers selected for inclusion in the qualitative review, 10 for meta-synthesis (N=2039). Significant heterogeneity was found in screening tests used to identify women eligible for TA and in methods to ascertain side effects. The most commonly reported side effect during treatment was pain (70%, 95% CI 52% to 85%; I2=98.01%) (8 studies; n=1454). No women discontinued treatment due to pain. At treatment follow-up, common side effects included vaginal discharge (72%, 95% CI 18% to 100%; I2=99.55%) (5 studies; n=771) and bleeding (38%, 95% CI 15% to 64%; I2=98.14%) (4 studies; n=856). Satisfaction with treatment was high in 99% (95% CI 98% to 100%; I2=0.00%) of women (3 studies; n=679). Conclusions TA results in a number of common side effects, though acceptability remains high among women treated in LMICs. Standardised side effect and acceptability reporting are needed as TA becomes more readily available. PROSPERO registration number CRD42020197605.

Abstract
Multiple barriers impede the transformation of evidence-based research into implementation of cervical cancer screening in ASEAN countries. This review is the first of its kind to show the disease burden of cervical cancer, progress till date to implement screening and corresponding challenges, and propose tailored solutions to promote cervical cancer prevention in ASEAN. In 2020, approximately 69 000 cervical cancer cases and 38 000 deaths happened in ASEAN, and more than 44% and 63% increases on new cases and deaths are expected in 2040. Only four countries have initiated population-based cervical cancer screening programs, but the participation rate is less than 50% in some countries and even lower than 10% in Myanmar and Indonesia. Inequity and unavailability in service delivery, lack of knowledge and awareness, limited follow-up and treatment capacity, and funding sustainability affect successful scale-up of cervical cancer screening most in ASEAN. Implementing HPV detection-based primary screening, appropriate management of screen-positives, enhancing health education, integrating health services can accelerate reduction of cervical cancer burden in ASEAN. Achieving high screening coverage and high treatment compliance will help ASEAN countries remain aligned to cervical cancer elimination strategies.

Abstract
Introduction Although ultrasonography has been reported to have similar diagnostic accuracy to magnetic resonance imaging, it is not a standard imaging modality for cervical cancer. We aimed to summarize the ultrasonographic features of rare primary cervical cancer. Methods This was a retrospective study of patients with cervical cancer who were diagnosed between June 2014 and October 2019. They were divided into common-type cervical cancer (ie, cervical squamous cell carcinoma) and rare-type cervical cancer groups including adenocarcinoma, adenosquamous carcinoma, and small cell carcinoma. All patients were staged according to the tumor, nodes, and metastases criteria. Results Of the 64 patients, the diagnosis was suspected on ultrasonography in 61 (95.3%) patients and missed on ultrasonography in three patients. The tumor size was smaller in the rare-type cervical cancer group (p<0.05). Hypoechoic lesions in common-type cervical cancer and isoechoic lesions accounted for 74.4% (32/43) and 61.9% (13/21) of patients in the rare-type cervical cancer group, respectively (p<0.001). Meanwhile, 67.4% (29/43) of tumors in common-type cervical cancer were exophytic, while 66.7% (14/21) in rare-type cervical cancer were endophytic (p=0.01). Color Doppler blood signals, as compared with normal cervical tissue, were found in all patients. There was good consistency between ultrasonographic and pathologic diagnosis of rare-type cervical cancer (weighted kappa=0.87). Conclusions Most patients with rare-type cervical cancer present with isoechoic lesions. The coincidence rate between ultrasonographic and pathologic diagnosis of rare-type cervical cancer is 87%.

[PMID: 34342174 PMCID: PMC8419757 DOI: 10.1002/cam4.4152] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2021] [Revised: 06/24/2021] [Accepted: 06/27/2021] [Indexed: 12/28/2022] Open
Abstract
OBJECTIVES To evaluate the clinical performance of liquid-based cytology (LBC), HPV tests and visual inspections with acetic acid or Lugol's iodine (VIA/VILI) as primary screening and triage strategies among Chinese women living with HIV (WLHIV). METHODS WLHIV aged 18 years and older were recruited from HIV/AIDS treatment clinic in Yunnan, China from 2019 to 2020. Women were screened with self- and physician-sampling for HPV tests, LBC, and VIA/VILI. Women positive for any HPV or with cytological abnormalities were recalled for colposcopy examination and biopsy when necessary. Clinical performance of primary and triage strategies for detecting cervical intraepithelial neoplasia grade 2 or worse (CIN2+) was evaluated. RESULTS For primary screening, sensitivity of physician-HPV tests was 100%, 89.5%, and 100% for hybrid capture 2 (HC2), cobas, and Sansure HPV, and specificity was 80.4%, 85.1%, and 72.0%, respectively. Self-HPV test achieved considerable performance with physician-HPV. Sensitivity and specificity were 61.1% and 96.3% for LBC (atypical squamous cells of undetermined significance or worse [ASCUS+]), 40.0% and 77.3% for VIA/VILI. For triaging HPV-positive women, LBC (ASCUS+), HPV-16/18 genotyping, and VIA/VILI-elevated specificity with sensitivity declined 30%-50% compared with HPV screening alone. Restricted HPV genotyping triage (HPV-16/18/31/33/45/52/58) demonstrated the optimal accuracy (89.5% sensitivity, 81.9% specificity), and was similar to HPV-16/18 with reflex LBC (ASCUS+). Combination antiretroviral therapies (cARTs) <2 years were associated with decreased specificity of HC2 (aOR: 1.87, 95% CI: 1.22-3.91) and Sansure HPV (2.48, 1.43-4.29). CONCLUSIONS Self-HPV with restricted genotyping triage is highly recommended for cervical cancer screening for WLHIV in China. Feasible triage to increase HPV specificity among women with short duration of cART is needed.

Abstract
Cervical intraepithelial neoplasia (CIN) is the abnormal growth of cells on the surface of the cervix that could potentially lead to cervical cancer. In the present study, we investigated whether measuring the neutrophil-lymphocyte ratio (NLR) can be useful for predicting the risks of developing cervical lesions.This is a retrospective analysis of 212 women who were enrolled in this study. Among them, 106 patients with histologically confirmed CIN1-3 who were treated with loop electrosurgical excision procedure or cold knife cone in the Department of Gynecology, The Affiliated Hospital of Inner Mongolia Medical University between July 30th 2016 and January 30th 2019.Among the 106 patients in the CIN group, cytology showed minor abnormality which included atypical squamous cells of undetermined significance or low-grade squamous intraepithelial lesion in 42, high-grade squamous intraepithelial lesion in 62, and squamous cell carcinoma in 2 patients. We found that the NLR has no significant difference between the control group and the CIN1 group, while there were significant differences between CIN1 and CIN2, and CIN2 and CIN3 group. The median of the NLR was higher in the HPV16-persistent groups than in the HPV-negative group.In conclusion, a high NLR value independently predicts CIN and the stage of CIN. The NLR may help doctors evaluate outcomes of patients received conization and choose alternative therapies for patients with high NLR value.

Efficacy of point-of-care thermal ablation among high-risk human papillomavirus positive women in China. Int J Cancer 2021; 148:1419-1427. [PMID: 32895912 DOI: 10.1002/ijc.33290] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/15/2020] [Revised: 08/17/2020] [Accepted: 08/31/2020] [Indexed: 02/06/2023]
Abstract
Thermal ablation is a point-of-care ablative treatment technique for cervical intraepithelial neoplasia (CIN). However, limited information is available about its efficacy in low- and middle-income countries. We evaluated the efficacy of thermal ablation in treatment of CIN detected through high-risk human papillomavirus (HPV) screening in China. Women positive on high-risk HPV and having colposcopically suspected lesions eligible for ablation underwent colposcopy, biopsy and thermal ablation in one visit. Women ineligible were recalled for large loop excision of transformation zone (LLETZ) when histopathology results were high-grade CIN. Posttreatment follow-up at 6 months or more was with HPV test and cytology followed by colposcopy and biopsy for HPV and/or cytology-positive women. Cure was defined as either negative cytology and HPV test or absence of histopathology proved CIN in any positive women. Of total 218 HPV-positive women treated with thermal ablation (n = 170) or LLETZ (n = 48), 196 reported for follow-up evaluation. For women with histologically confirmed CIN at baseline (thermal ablation-104; LLETZ-38), cure rates were 84.6% for thermal ablation and 86.8% for LLETZ. Cure rates after thermal ablation were 90.3% for CIN grade one (CIN1) and 76.2% for CIN grade two or worse (CIN2+). HPV clearance rate was 80.4% in women undergoing thermal ablation, which was lower for HPV16/18 compared to other oncogenic types (67.6% vs 85.7%). HPV test had a negative predictive value (NPV) of 98.7% to detect CIN2+ at follow-up and the positive predictive value (PPV) was 40.4%. Thermal ablation is effective to treat CIN as well as to clear the high-risk HPV infection. HPV test has high PPV and NPV in following up patients posttreatment.

Effect of Sequential Rounds of Cervical Cancer Screening on Management of HPV-positive Women: A 15-year Population-based Cohort Study from China. Cancer Prev Res (Phila) 2020; 14:363-372. [PMID: 33303694 DOI: 10.1158/1940-6207.capr-20-0456] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/02/2020] [Revised: 10/09/2020] [Accepted: 12/03/2020] [Indexed: 11/16/2022]
Abstract
Women are anticipated to go through more than two rounds of cervical screening in their lifetime. Human papillomavirus (HPV) testing is increasingly used as the primary cervical cancer screening test. However, triage strategies for HPV-positive women were usually evaluated at baseline screening. We assessed the effect of sequential rounds of cervical screening on several algorithms for HPV triage. A total of 1,997 women ages 35-45 years were enrolled in 1999 in Shanxi, P.R. China and followed up three times at approximately 5-year intervals. Cervical intraepithelial neoplasia (CIN) grade 2 or worse (CIN2+) prevalence by prior HPV results and performance of 12 triage algorithms with cytology, genotyping, and prior HPV were examined among 229 HPV-positive women at the fourth round. CIN2+ prevalence varied from 56.5% (95% confidence interval, 36.8%-74.4%) following 15 years HPV persistence to 3.5% (1.2%-9.9%) with an incident HPV within 15 years. Triage with cytology (with threshold of atypical squamous cells of undetermined significance) yielded positive predictive value (PPV) of 21.4% (13.8%-29.0%), entailing immediate colposcopic referral, and negative predictive value (NPV) of 97.4% (94.6%-100%), permitting retesting at short intervals. Triage with genotyping (16/18/31/33/45/52/58) or prior HPV results showed comparable performance with cytology. Among 11 triage algorithms with similar NPV to cytology, triage with prior HPV results and reflex genotyping (16/18) achieved highest PPV of 28.9% (18.8%-39.1%) and lowest colposcopy referral of 33.2% (27.4%-39.5%). HPV persistence across rounds is an effective risk stratifier in HPV-positive women. Mainstream cytology and genotyping, with or without consideration of prior HPV results, remain effective for HPV triage at fourth round. PREVENTION RELEVANCE: The study highlights the sustained effectiveness of mainstream HPV triage methods, such as cytology and genotyping, after sequential rounds of cervical screening. It also suggests that use of HPV persistence across rounds can improve management of HPV-positive women in cervical cancer screening.

Ecancermedicalscience 2020; 14:1138. [PMID: 33281930 PMCID: PMC7685770 DOI: 10.3332/ecancer.2020.1138] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2020] [Indexed: 11/06/2022] Open
Abstract
Introduction Screening for cervical cancer (CC) prevention has substantially changed with the introduction of human papillomavirus (HPV) tests. This technology compared to cytology has increased the detection of pre-malignant and malignant cervical lesions in real-world programmes in different settings. Very importantly, through self-collection, HPV testing can reduce barriers to screening and increase coverage. However, when using HPV self-collection, triage tests are a key step in the CC prevention process, and high adherence to triage has been difficult to obtain in low-middle income settings. The aim of this study was to measure adherence to triage among women with HPV+ self-collection and analysed factors associated with this adherence in a middle-low resource setting in Argentina. We also evaluated key indicators related to the implementation of the HPV self-collection strategy. Methods We analysed data on screening/triage/diagnosis/treatment from women aged 30+ who performed self-collection between 2015 and 2017 (n = 15,763), in the public health system in Tucuman, Argentina. We analysed secondary data from the national screening information system. The primary outcomes were: 1) adherence to cytology triage within the recommended timeframe (120 days) and 2) overall adherence to cytology triage including data at 18 months after screening. Multivariable regression was used to examine the association between age group, year of the screening test, record of the previous Pap-based screening and health insurance status with adherence to triage test as a primary outcome. We reported odds ratios, 95% confidence intervals and p-value of 0.05, which was considered the threshold for p-values). Results We analysed data of 2,389 HPV+ women. The overall adherence to triage at 18 months was 42.9%. The percentage of women completing cytology triage within the recommended timeframe of 120 days was lower (25.2%). Women with the record of a previous Pap-based screening had 1.86 times the odds of having a triage compared to women without a record of a previous Pap-based screening (95% CI: 1.64–2.64, p <0.001). Furthermore, the probability of having triage at the recommended timeframe was higher among women who were older and women with public health insurance. Conclusions Our results showed that adherence to triage in the recommended timeframe was low. In addition, the probability of having triage at the recommended timeframe was higher among women with a record of a previous Pap-based screening, a proxy of the use of health services. Our results showed that adherence to triage in the context of the HPV-self-collection strategy is challenging. The implementation of alternative approaches that might facilitate adherence to triage should be further investigated.

Cancer Res Treat 2020; 53:212-222. [PMID: 32878425 PMCID: PMC7812020 DOI: 10.4143/crt.2020.219] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/13/2020] [Accepted: 08/31/2020] [Indexed: 02/06/2023] Open
Abstract
Purpose This study attempted to detect the changes of cervical cancer screening rate and willingness among female migrants, and the associated socio-demographic factors in Shenzhen city. Materials and Methods Two citywide surveys were conducted using a multistage random cluster sampling method in 2011 and 2014, respectively. Data on demographic characteristics, screening participation, and willingness to screen were collected. Logistic regression models were applied to detect possible associated socio-demographic characteristics, and their variations with survey years. Results In total, 12,017 female migrants were enrolled, with a mean age (standard deviation) of 36.73 (6.55) years. From 2011 to 2014, the screening rate increased (25.8% vs. 35.1%, p < 0.001), while the willingness to screen remained stable (82.2% vs. 82.8%, p=0.46). Overall, socio-demographic characteristics of female migrants, including age, marital status, education, monthly income, employment, and medical insurance, were found to be positively associated with screening participation. Similar impacts in relation to willingness were observed except for age. However, these associations varied with survey years, mainly in the contributions of education and monthly income to screening participation, as well as age, monthly income, and medical insurance to willingness of being screened. Conclusion Identifying changes of associated socio-demographic factors precisely is warranted of necessity, which provides novel clues to adjust targeted actions regularly in promoting cervical cancer screening participation among female migrants in Shenzhen.
