RESUMO
Lung cancer is the leading cause of mortality and person-years of life lost from cancer among US men and women. Early detection has been shown to be associated with reduced lung cancer mortality. Our objective was to update the American Cancer Society (ACS) 2013 lung cancer screening (LCS) guideline for adults at high risk for lung cancer. The guideline is intended to provide guidance for screening to health care providers and their patients who are at high risk for lung cancer due to a history of smoking. The ACS Guideline Development Group (GDG) utilized a systematic review of the LCS literature commissioned for the US Preventive Services Task Force 2021 LCS recommendation update; a second systematic review of lung cancer risk associated with years since quitting smoking (YSQ); literature published since 2021; two Cancer Intervention and Surveillance Modeling Network-validated lung cancer models to assess the benefits and harms of screening; an epidemiologic and modeling analysis examining the effect of YSQ and aging on lung cancer risk; and an updated analysis of benefit-to-radiation-risk ratios from LCS and follow-up examinations. The GDG also examined disease burden data from the National Cancer Institute's Surveillance, Epidemiology, and End Results program. Formulation of recommendations was based on the quality of the evidence and judgment (incorporating values and preferences) about the balance of benefits and harms. The GDG judged that the overall evidence was moderate and sufficient to support a strong recommendation for screening individuals who meet the eligibility criteria. LCS in men and women aged 50-80 years is associated with a reduction in lung cancer deaths across a range of study designs, and inferential evidence supports LCS for men and women older than 80 years who are in good health. The ACS recommends annual LCS with low-dose computed tomography for asymptomatic individuals aged 50-80 years who currently smoke or formerly smoked and have a ≥20 pack-year smoking history (strong recommendation, moderate quality of evidence). Before the decision is made to initiate LCS, individuals should engage in a shared decision-making discussion with a qualified health professional. For individuals who formerly smoked, the number of YSQ is not an eligibility criterion to begin or to stop screening. Individuals who currently smoke should receive counseling to quit and be connected to cessation resources. Individuals with comorbid conditions that substantially limit life expectancy should not be screened. These recommendations should be considered by health care providers and adults at high risk for lung cancer in discussions about LCS. If fully implemented, these recommendations have a high likelihood of significantly reducing death and suffering from lung cancer in the United States.

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.

OBJECTIVES: The Enduring Consensus Cervical Cancer Screening and Management Guidelines (Enduring Guidelines) effort is a standing committee to continuously evaluate new technologies and approaches to cervical cancer screening, management, and surveillance. METHODS AND RESULTS: The Enduring Guidelines process will selectively incorporate new technologies and approaches with adequate supportive data to more effectively improve cancer prevention for high-risk individuals and decrease unnecessary procedures in low-risk individuals. This manuscript describes the structure, process, and methods of the Enduring Guidelines effort. Using systematic literature reviews and primary data sources, risk of precancer will be estimated and recommendations will be made based on risk estimates in the context of established risk-based clinical action thresholds. The Enduring Guidelines process will consider health equity and health disparities by assuring inclusion of diverse populations in the evidence review and risk assessment and by developing recommendations that provide a choice of well-validated strategies that can be adapted to different settings. CONCLUSIONS: The Enduring Guidelines process will allow updating existing cervical cancer screening and management guidelines rapidly when new technologies are approved or new scientific evidence becomes available.

OBJECTIVES: The Enduring Consensus Cervical Cancer Screening and Management Guidelines Committee developed recommendations for dual stain (DS) testing with CINtec PLUS Cytology for use of DS to triage high-risk human papillomavirus (HPV)-positive results. METHODS: Risks of cervical intraepithelial neoplasia grade 3 or worse were calculated according to DS results among individuals testing HPV-positive using data from the Kaiser Permanente Northern California cohort and the STudying Risk to Improve DisparitiES study in Mississippi. Management recommendations were based on clinical action thresholds developed for the 2019 American Society for Colposcopy and Cervical Pathology Risk-Based Management Consensus Guidelines. Resource usage metrics were calculated to support decision-making. Risk estimates in relation to clinical action thresholds were reviewed and used as the basis for draft recommendations. After an open comment period, recommendations were finalized and ratified through a vote by the Consensus Stakeholder Group. RESULTS: For triage of positive HPV results from screening with primary HPV testing (with or without genotyping) or with cytology cotesting, colposcopy is recommended for individuals testing DS-positive. One-year follow-up with HPV-based testing is recommended for individuals testing DS-negative, except for HPV16- and HPV18-positive results, or high-grade cytology in cotesting, where immediate colposcopy referral is recommended. Risk estimates were similar between the Kaiser Permanente Northern California and STudying Risk to Improve DisparitiES populations. In general, resource usage metrics suggest that compared with cytology, DS requires fewer colposcopies and detects cervical intraepithelial neoplasia grade 3 or worse earlier. CONCLUSIONS: Dual stain testing with CINtec PLUS Cytology is acceptable for triage of HPV-positive test results. Risk estimates are portable across different populations.

BACKGROUND: The 2019 American Society for Colposcopy and Cervical Pathology (ASCCP) risk-based management consensus guidelines are the most recent national guidelines for the management of abnormal cervical cancer screening tests. These guidelines benefit patients by concentrating testing and treatment in those at highest cervical cancer risk. Adoption of guidelines often occurs slowly, with few studies examining the factors associated with guideline-adherent management of abnormal results. METHODS: To elucidate the factors associated with the use of the 2019 ASCCP guidelines among clinicians who perform cervical cancer screening, physicians and advanced practice professionals who perform cervical cancer screening were cross-sectionally surveyed. Clinicians responded to screening vignettes with differing recommendations for management between the 2019 and prior management guidelines. Screening vignette 1 involved reduction of invasive testing on a low-risk patient; screening vignette 2 involved increased surveillance testing on a high-risk patient. Binomial logistic regression models determined the factors associated with the use of the 2019 guidelines. RESULTS: A total of 1251 clinicians participated from across the United States. For screening vignettes 1 and 2, guideline-adherent responses were given by 28% and 36% of participants, respectively. Management recommendations differed by specialty and were incorrect in different situations: there was inappropriate invasive testing by obstetrics and gynecology physicians (vignette 1) and inappropriate discontinuation of screening by family and internal medicine physicians (vignette 2). Regardless of their chosen response, over half erroneously believed they were guideline adherent. CONCLUSIONS: Many clinicians who believe they are following appropriate guidelines may not realize their management strategy is inconsistent with the 2019 guidelines. Education initiatives tailored to clinician specialty could address the understanding of current guidelines, encourage the use of updated guidelines, maximize patient benefits, and minimize harms. PLAIN LANGUAGE SUMMARY: The 2019 American Society for Colposcopy and Cervical Pathology risk-based management consensus guidelines are the most recent national guidelines for abnormal cervical cancer screening test management. We surveyed over 1200 obstetrics and gynecology (OB/GYN), family medicine, and internal medicine physicians and advanced practice providers about their screening and abnormal results follow-up practices in relation to guidelines. Few clinicians are following the 2019 guidelines. Management recommendations differed by clinician specialty and were incorrect in different situations: there was inappropriate invasive testing by OB/GYN physicians and inappropriate screening discontinuation by family and internal medicine physicians. Education tailored by clinician specialty could address the understanding of current guidelines, encourage the use of updated guidelines, maximize patient benefits, and minimize harms.

BACKGROUND: Cervical screening has not effectively controlled cervical adenocarcinoma (AC). Human papillomavirus (HPV) testing is recommended for cervical screening but the optimal management of HPV-positive individuals to prevent AC remains a question. Cytology and HPV typing are two triage options to predict the risk of AC. We combined two potential biomarkers (atypical glandular cell, AGC, cytology and HPV-types 16, 18, or 45) to assess their joint effect on detecting AC. METHODS: Kaiser Permanente Northern California (KPNC) used triennial co-testing with cytology and HPV testing (positive/negative) for routine cervical screening between 2003 and 2020. HPV typing of a sample of residual HPV test specimens was performed on a separate cohort selected from KPNC (Persistence and Progression, PaP, cohort). We compared risk of prevalent and incident histologic AC/AIS (adenocarcinoma in situ) associated with preceding combinations of cytologic results and HPV typing. Risk of squamous cell cancer (SCC)/cervical intraepithelial neoplasia grade 3 (CIN3) (SCC/CIN3) was also included for comparison. RESULTS: Among HPV-positive individuals in PaP cohort, 99% of prevalent AC and 96% of AIS were linked to HPV-types 16, 18, or 45 (denoted HPV 16/18/45). Although rare (0.09% of screening population), the concurrent detection of HPV 16/18/45 with AGC cytology predicted a highly elevated relative risk of underlying histologic AC/AIS; the absolute risk of diagnosing AC/AIS was 12% and odds ratio (OR) was 1341 (95%CI:495-3630) compared to patients with other high-risk HPV types and normal cytology. Cumulatively (allowing non-concurrent results), approximately one-third of the AC/AIS cases ever had HPV 16/18/45 and AGC cytology (OR = 1785; 95%CI:872-3656). AGC was not as strongly associated with SCC/CIN3. CONCLUSION: Detection of HPV 16/18/45 positivity elevates risk of adenocarcinoma, particularly if AGC cytology is also found.

INTRODUCTION: The underrepresentation of Black, Indigenous, and People of Color (BIPOC) individuals in healthcare research limits generalizability and contributes to healthcare inequities. Existing barriers and attitudes toward research participation must be addressed to increase the representation of safety net and other underserved populations. METHODS: We conducted semi-structured qualitative interviews with patients at an urban safety net hospital, focusing on facilitators, barriers, motivators, and preferences for research participation. We conducted direct content analysis guided by an implementation framework and used rapid analysis methods to generate final themes. RESULTS: We completed 38 interviews and identified six major themes related to preferences for engagement in research participation: (1) wide variation in research recruitment preferences; (2) logistical complexity negatively impacts willingness to participate; (3) risk contributes to hesitation toward research participation; (4) personal/community benefit, interest in study topic, and compensation serve as motivators for research participation; (5) continued participation despite reported shortcomings of informed consent process; and (6) mistrust could be overcome by relationship or credibility of information sources. CONCLUSION: Despite barriers to participation in research studies among safety-net populations, there are also facilitators that can be implemented to increase knowledge and comprehension, ease of participation, and willingness to join research studies. Study teams should vary recruitment and participation methods to ensure equal access to research opportunities. PATIENT/PUBLIC CONTRIBUTION: Our analysis methods and study progress were presented to individuals within the Boston Medical Center healthcare system. Through this process community engagement specialists, clinical experts, research directors, and others with significant experience working with safety-net populations supported data interpretation and provided recommendations for action following the dissemination of data.

BACKGROUND: Vaccines are a strong public health tool to protect against severe disease, hospitalization, and death from COVID-19. Still, inequities in COVID-19 vaccination rates and health outcomes continue to exist among Black and Latino populations. Boston Medical Center (BMC) has played a significant role in vaccinating medically underserved populations, and organized a series of community-engaged conversations to better understand community concerns regarding the COVID-19 vaccine. This paper describes the themes which resulted from these community-engaged conversations and proposes next steps for healthcare leaders. METHODS: We accessed nine publicly available recordings of the community-engaged conversations which were held between March 2021 and September 2021 and ranged from 8 to 122 attendees. Six conversations prioritized specific groups: the Haitian-Creole community, the Cape Verdean community, the Latino community, the Black Christian Faith community, guardians who care for children living with disabilities, and individuals affected by systemic lupus erythematosus. Remaining conversations targeted the general public of the Greater Boston Area. We employed a Consolidated Framework for Implementation Research-driven codebook to code our data. Our analysis utilized a modified version of qualitative rapid analysis methods. RESULTS: Five main themes emerged from these community-engaged conversations: (1) Structural factors are important barriers to COVID-19 vaccination; (2) Mistrust exists due to the negative impact of systemic oppression and perceived motivation of the government; (3) There is a desire to learn more about biological and clinical characteristics of the COVID-19 vaccine as well as the practical implications of being vaccinated; (4) Community leaders emphasize community engagement for delivering COVID-19 information and education and; (5) Community leaders believe that the COVID-19 vaccine is a solution to address the pandemic. CONCLUSION: This study illustrates a need for community-engaged COVID-19 vaccine messaging which reflects the nuances of the COVID-19 vaccine and pandemic without oversimplifying information. In highlighting common concerns of the Greater Boston Area which contribute to a lack of confidence in the COVID-19 vaccine, we underscore important considerations for public health and healthcare leadership in the development of initiatives which work to advance health equity.

Cervical cancer screening plays a major role in preventing cervical cancer. The field is based on understanding the natural history of human papillomavirus and its role in cervical cancer. Screening has evolved to assessing the risk for cervical intraepithelial neoplasia grade 3, a true cancer precursor, and performing diagnostic tests based on those risks. This article summarizes the present state of management of abnormal cervical cancer screening tests in the United States, based on the most recent 2019 American Society of Colposcopy and Cervical Pathology guidelines.

OBJECTIVE: The most recent guidelines for colposcopy practice in the United States, the 2017 Colposcopy Standards Consensus Guidelines, did not include recommendations for endocervical curettage (ECC). This document provides updated guidelines for use of ECC among patients referred for colposcopy. METHODS: Consensus guidelines for the use of ECC were developed in 2012. To update these guidelines in concordance with the 2017 Colposcopy Standards process, an expert workgroup was convened in 2021. Literature had been previously reviewed through 2011, before the 2012 guideline. Literature from the years 2012-2021 and data from the NCI Biopsy study were reviewed, focusing on the additional yield of ECC. RESULTS: Endocervical curettage is recommended for patients with high-grade cytology, human papillomavirus 16/18 infection, positive results on dual staining for p16/Ki67, for those previously treated for known or suspected cervical precancer or considering observation of cervical intraepithelial neoplasia grade 2, and when the squamocolumnar junction is not fully visualized at colposcopy. Endocervical curettage is preferred for all patients aged older than 40 years. Endocervical curettage is acceptable for all nonpregnant patients undergoing colposcopy but may be omitted when a subsequent excisional procedure is planned, the endocervical canal does not admit a sampling device, or in nulliparous patients aged younger than 30 years, with cytology reported as atypical squamous cells of undetermined significance or low-grade squamous intraepithelial lesion regardless of whether the squamocolumnar junction is fully visualized. Endocervical curettage is unacceptable in pregnancy. CONCLUSIONS: These guidelines for ECC add to the 2017 consensus recommendations for colposcopy practice in the United States.

Importance: Each year in the US, approximately 100â¯000 people are treated for cervical precancer, 14â¯000 people are diagnosed with cervical cancer, and 4000 die of cervical cancer. Observations: Essentially all cervical cancers worldwide are caused by persistent infections with one of 13 carcinogenic human papillomavirus (HPV) genotypes: 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, and 68. HPV vaccination at ages 9 through 12 years will likely prevent more than 90% of cervical precancers and cancers. In people with a cervix aged 21 through 65 years, cervical cancer is prevented by screening for and treating cervical precancer, defined as high-grade squamous intraepithelial lesions of the cervix. High-grade lesions can progress to cervical cancer if not treated. Cervicovaginal HPV testing is 90% sensitive for detecting precancer. In the general population, the risk of precancer is less than 0.15% over 5 years following a negative HPV test result. Among people with a positive HPV test result, a combination of HPV genotyping and cervical cytology (Papanicolaou testing) can identify the risk of precancer. For people with current precancer risks of less than 4%, repeat HPV testing is recommended in 1, 3, or 5 years depending on 5-year precancer risk. For people with current precancer risks of 4% through 24%, such as those with low-grade cytology test results (atypical squamous cells of undetermined significance [ASC-US] or low-grade squamous intraepithelial lesion [LSIL]) and a positive HPV test of unknown duration, colposcopy is recommended. For patients with precancer risks of less than 25% (eg, cervical intraepithelial neoplasia grade 1 [CIN1] or histologic LSIL), treatment-related adverse effects, including possible association with preterm labor, can be reduced by repeating colposcopy to monitor for precancer and avoiding excisional treatment. For patients with current precancer risks of 25% through 59% (eg, high-grade cytology results of ASC cannot exclude high-grade lesion [ASC-H] or high-grade squamous intraepithelial lesion [HSIL] with positive HPV test results), management consists of colposcopy with biopsy or excisional treatment. For those with current precancer risks of 60% or more, such as patients with HPV-16-positive HSIL, proceeding directly to excisional treatment is preferred, but performing a colposcopy first to confirm the need for excisional treatment is acceptable. Clinical decision support tools can facilitate correct management. Conclusions and Relevance: Approximately 100â¯000 people are treated for cervical precancer each year in the US to prevent cervical cancer. People with a cervix should be screened with HPV testing, and if HPV-positive, genotyping and cytology testing should be performed to assess the risk of cervical precancer and determine the need for colposcopy or treatment. HPV vaccination in adolescence will likely prevent more than 90% of cervical precancers and cancers.

Some reproductive-aged individuals remain unvaccinated against coronavirus disease 2019 (COVID-19) because of concerns about potential adverse effects on fertility. Using data from an internet-based preconception cohort study, we examined the associations of COVID-19 vaccination and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection with fertility among couples trying to conceive spontaneously. We enrolled 2,126 self-identified female participants aged 21-45 year residing in the United States or Canada during December 2020-September 2021 and followed them through November 2021. Participants completed questionnaires every 8 weeks on sociodemographics, lifestyle, medical factors, and partner information. We fit proportional probabilities regression models to estimate associations between self-reported COVID-19 vaccination and SARS-CoV-2 infection in both partners with fecundability (i.e., the per-cycle probability of conception), adjusting for potential confounders. COVID-19 vaccination was not appreciably associated with fecundability in either partner (female fecundability ratio (FR) = 1.08, 95% confidence interval (CI): 0.95, 1.23; male FR = 0.95, 95% CI: 0.83, 1.10). Female SARS-CoV-2 infection was not strongly associated with fecundability (FR = 1.07, 95% CI: 0.87, 1.31). Male infection was associated with a transient reduction in fecundability (for infection within 60 days, FR = 0.82, 95% CI: 0.47, 1.45; for infection after 60 days, FR = 1.16, 95% CI: 0.92, 1.47). These findings indicate that male SARS-CoV-2 infection may be associated with a short-term decline in fertility and that COVID-19 vaccination does not impair fertility in either partner.

OBJECTIVE: To explore rates of under- and overscreening for cervical cancer among a national cohort. METHODS: The MarketScan database, a national administrative database of employee-sponsored insurance, was queried for elements relevant to cervical cancer screening among women aged 21-65 with 6 years of continuous enrollment (2015-2019). Average-risk women were defined as those without high-risk medical conditions or abnormal screening histories, and without evidence of hysterectomy with removal of the cervix for benign indications. Average-risk women were considered adequately screened if they had Pap tests alone at 2.5-3.5 year intervals, or HPV tests or co-tests at 4.5-5.5 year intervals. Logistic regressions were used to predict the odds of receiving guideline-adherent screening, underscreening, and overscreening. RESULTS: Among 1,872,809 eligible patients, 1,471,063 (78.5%) qualified for routine screening. Of these, only 18.1% received guideline-adherent screening, and 25.4% were unscreened during the 6-year period. Younger women (aged 21-39) were more likely to be overscreened [OR 1.46]. Older women (aged 50-64) were more likely to be underscreened or unscreened during the study period [OR 2.54]. Guideline-adherent screening was highest with HPV testing alone (80%) followed by co-testing (44%), and lowest with cytology alone (15%). A total of 329,062 women in this general population sample (18%) met high-risk criteria that required increased frequency of screening. CONCLUSIONS: High rates of both underscreening and overscreening indicate a need for additional strategies to improve guideline-adherent care. CLINICAL TRIAL REGISTRATION: N/A.

OBJECTIVE: Colposcopy is an important part of cervical screening/management programs. Colposcopic appearance is often classified, for teaching and telemedicine, based on static images that do not reveal the dynamics of acetowhitening. We compared the accuracy and reproducibility of colposcopic impression based on a single image at one minute after application of acetic acid versus a time-series of 17 sequential images over two minutes. METHODS: Approximately 5000 colposcopic examinations conducted with the DYSIS colposcopic system were divided into 10 random sets, each assigned to a separate expert colposcopist. Colposcopists first classified single two-dimensional images at one minute and then a time-series of 17 sequential images as 'normal,' 'indeterminate,' 'high grade,' or 'cancer'. Ratings were compared to histologic diagnoses. Additionally, 5 colposcopists reviewed a subset of 200 single images and 200 time series to estimate intra- and inter-rater reliability. RESULTS: Of 4640 patients with adequate images, only 24.4% were correctly categorized by single image visual assessment (11% of 64 cancers; 31% of 605 CIN3; 22.4% of 558 CIN2; 23.9% of 3412 < CIN2). Individual colposcopist accuracy was low; Youden indices (sensitivity plus specificity minus one) ranged from 0.07 to 0.24. Use of the time-series increased the proportion of images classified as normal, regardless of histology. Intra-rater reliability was substantial (weighted kappa = 0.64); inter-rater reliability was fair ( weighted kappa = 0.26). CONCLUSION: Substantial variation exists in visual assessment of colposcopic images, even when a 17-image time series showing the two-minute process of acetowhitening is presented. We are currently evaluating whether deep-learning image evaluation can assist classification.

BACKGROUND: The guidelines for managing abnormal cervical cancer screening tests changed from a results-based approach in 2012 to a risk-based approach in 2019. OBJECTIVE: We estimated the cost-effectiveness of the 2019 management guidelines and the changes in resource utilization moving from 2012 to 2019 guidelines. STUDY DESIGN: We utilized a previously published model of cervical cancer natural history and screening to estimate and compare the lifetime costs and the number of screens, colposcopies, precancer treatments, cancer cases, and cancer deaths associated with the 2012 vs 2019 management guidelines. We assessed these guidelines under the scenarios of observed screening practice and perfect screening adherence to 3-year cytology starting at age 21, with a switch to either 3-year or 5-year cytology plus human papillomavirus cotesting at age 30. In addition, we estimated the lifetime costs and life years to determine the cost-effectiveness of shifting to the 2019 management guidelines. RESULTS: Under the assumptions of both observed screening practice and perfect screening adherence with a strategy of 3-year cytology at ages 21 to 29 and switching to 3-year cotesting at age 30, the management of the screening tests according to the 2019 guidelines was less costly and more effective than the 2012 guidelines. For 3-year cytology screening at ages 21 to 29 and switching to 5-year cotesting at age 30, the 2019 guidelines were more cost-effective at a willingness-to-pay threshold of $100,000 per life year gained. Across all scenarios, the 2019 management guidelines were associated with fewer colposcopies and cancer deaths. CONCLUSION: Our model-based analysis suggests that the 2019 guidelines are more effective overall and also more cost-effective than the 2012 guidelines, supporting the principle of "equal management of equal risks."

This invited commentary discusses the article by Richards et al. describing differences in rates of on-time HPV vaccination and cervical cancer screening in 2018 among enrollees in different insurance plans. The commentary focuses on the larger problem of low vaccination HPV rates and decreasing cervical cancer screening rates seen across all sectors. We outline challenges posed by the COVID-19 pandemic on HPV vaccination and cervical cancer screening, and discuss opportunities to improve cervical cancer prevention.

OBJECTIVE: The aim of the study was to evaluate the long-term sustainability of a multilevel intervention and the COVID-19 pandemic impact on adolescent human papillomavirus (HPV) vaccination coverage. MATERIALS AND METHODS: In 2016, a pediatric and family medicine practice within a federally qualified health center completed a multilevel intervention, Development of Systems and Education for Human Papillomavirus Vaccination. We examined the intervention impact on HPV vaccine initiation and completion rates among adolescents 10-18 years between March 2016 and October 2020. We determined the total number of HPV vaccine doses administered monthly. Data were plotted on statistical process control charts. RESULTS: Vaccine initiation increased from an average of 14% to an average of 42% for 10-year-old patients and from an average of 72% to an average of 92% for 11- to 12-year-old patients between March 2016 and January 2017 and remained stable through March 2020. Complete vaccination by age 13 years increased from 62% to 88% through October 2020. CONCLUSIONS: This intervention led to continued improvement for on-time HPV vaccination coverage 4 years after intervention completion.Clinical Trial Registration: This trial has been registered at http://www.clinicaltrials.gov (identifier NCT02812732).

OBJECTIVES: In the 2019 ASCCP Risk-Based Management Consensus Guidelines, clinical management decisions are based on immediate and 5-year cervical intraepithelial neoplasia (CIN) 3+ risk estimates. However, data for technologies other than human papillomavirus testing and cytology may be limited to clinical trials and observational studies of shorter duration than 5 years. To enable decisions about 1- or 3-year intervals, 3-year CIN 3+ risk equivalents to 5-year CIN 3+ risk thresholds were generated. MATERIALS AND METHODS: We examined screening test result scenarios around the 5-year risk thresholds of 0.15% and 0.55% and calculated the average percent increase in CIN 3+ risk from 3 to 5 years. Using this average increase, we obtained estimates of corresponding risk thresholds at 3 years. We then validated whether use of the 3-year risk threshold would have resulted in equivalent management per the 2019 recommendations. RESULTS: Around the 5-year CIN 3+ risk threshold of 0.55%, the average increase in risk from 3 to 5 years was 0.16%. Therefore, the equivalent threshold for 3-year risk was estimated as 0.39%. We found no difference in recommendations to return in 1 or 3 years using the 3-year or 5-year risk thresholds in 66 of the 67 scenarios (98.5%) in follow-up in 2019 guidelines. CONCLUSIONS: In this methodological addendum, the Enduring Guidelines Committee adopted the use of the 0.39% 3-year CIN 3+ risk threshold as equivalent of the 0.55% 5-year CIN 3+ risk threshold for technologies with fewer than 5 years of follow-up data. This allows evidence-based guidance for surveillance intervals of 1 or 3 years for new technologies with limited longitudinal data.

OBJECTIVE: The US screening and management guidelines for cervical cancer are based on the absolute risk of precancer estimated from large clinical cohorts and trials. Given the widespread transition toward screening with human papillomavirus (HPV) testing, it is important to assess which additional factors to include in clinical risk assessment to optimize management of HPV-infected women. MATERIALS AND METHODS: We analyzed data from HPV-infected women, ages 30-65 years, in the National Cancer Institute-Kaiser Permanente Northern California Persistence and Progression study. We estimated the influence of HPV risk group, cytology result, and selected cofactors on immediate risk of cervical intraepithelial neoplasia grade 3 or higher (CIN 3+) among 16,094 HPV-positive women. Cofactors considered included, age, race/ethnicity, income, smoking, and hormonal contraceptive use. RESULTS: Human papillomavirus risk group and cytology test result were strongly correlated with CIN 3+ risk. After considering cytology and HPV risk group, other cofactors (age, race/ethnicity, income, smoking, and hormonal contraceptive use) had minimal impact on CIN 3+ risk and did not change recommended management based on accepted risk thresholds. We had insufficient data to assess the impact of long-duration heavy smoking, parity, history of sexually transmitted infection, or immunosuppression. CONCLUSIONS: In our study at the Kaiser Permanente Northern California, the risk of CIN 3+ was determined mainly by HPV risk group and cytology results, with other cofactors having limited impact in adjusted analyses. This supports the use of HPV and cytology results in risk-based management guidelines.
