Impact Of SARS-CoV-2 Pandemic On The Diagnosis Of Cervical Cancer And Precursor Lesions - A Single Center Retrospective Study (preprint)

Objective: The aim of our study was to perform a retrospective analysis of the volume of cervical screening tests, the number of patients treated with an excision method, and the incidence of invasive and non-invasive cervical during a pandemic and pre-pandemic period of 24 months. Results: There was a statistically significant age difference between the two study periods, both by the average age of patients and by age group. The mean difference was 32 years before the pan-demic and 35 years during the pandemic (p-value >0.05). The majority of patients presenting for investigations before and during the pandemic were in the 30-39-year-old age group (31.95%, respectively; 34.2% (p-value = 0.003). The biggest patient loss ratio identified by age group was in the 50–59 years: 14,53% in the pre-pandemic period and 9,1% in the pandemic period. In the pan-demic period, patients from rural areas presented in the clinical trial with a lower rate of 39.52% (83 patients) vs. 60.47% (127 patients) in urban areas. A higher percentage of patients experiencing cervicorrhagia as a clinical manifestation in the pandemic period vs. the prepandemic period, with an increase in more severe lesions in the pandemic period, has a statistical significance of 8% more newly diagnosed compared to the pre-pandemic period. Conclusion: The addressability of the patients during the COVID period was not affected in a drastic way in our study. We encountered a decrease in appointments in the age group 50–59 years and a decrease in patients with rural residence. In our study, we found an increase in cervicorrhagia as a reason for consultation in the pandemic period with a higher lesion degree, both on a pap smear and on a cervical biopsy.

Prevalence and Genotype Distribution of Potential High-Risk and High-Risk Human Papillomavirus among Women attending Selected Reproductive Health Clinics in Lake Victoria Basin-Kenya: A Cross-sectional Study (preprint)

Background Persistent human papillomavirus (HPV) infection is considered the primary etiological factor for invasive cervical cancer. Understanding the epidemiology of circulating potential high-risk (HR) and HR HPV strains is essential in updating epidemiological knowledge and recommendations on genotype-specific vaccination development. In Lake Victoria Basin-LVB (Kisumu and Siaya Counties, Kenya), both the HIV burden, the post-COVID-19 pandemic environment and the population growth point to the need to study the current circulating strains. This study determined the prevalence and factors associated with Potential HR/HR HPV among women attending selected reproductive health clinics in LVB. The prevalence of Potential HR/HR HPV, genotype-specific distributions, and implications to the current HPV vaccination ongoing within Kenya are discussed. Methods A cross-sectional facility-based survey made up of 434 women aged 16-68 years was carried out in two selected facilities in the Urban-Kisumu County (Jaramogi Oginga Odinga Teaching and Referral Hospital-[JOOTRH] and rural-Siaya County (Gobei Health Center). Structured questionnaires were conducted to collect participant clinical and social characteristics. Cervical specimens were collected by registered reproductive health nurses and HPV genotyping was carried out using RIATOL HPV genotyping qPCR assay. Descriptive statistics followed by logistic binary regression was done using R version 4.3.2 Results The overall prevalence of potential HR/HR HPV among women attending the selected reproductive health clinics was reported at 36.5% (158/434). Specifically, in the rural setting, Gobei Health Center, the prevalence was 41.4% (41/99) while in the urban setting-JOOTRH, it was 34.6% (117/335). The most prevalent potential HR/HR HPV are 52, 67, 16, 31, 39, 45, and 31 for both HIV-positive and negative women and either in rural-Gobei Health Centre and Urban-JOOTRH. In this study, HIV status was not associated with potential HR/HR HPV among women attending. Age was the main factor associated with HPV infection among HIV-positive and negative women attending the selected reproductive health clinics in rural-urban Lake Victoria Basin, with women between the age of 30-39 having the highest risk (AOR=0.3, CI:0.2-0.7, p<0.001). Conclusion In both rural and urban regions, potential HR/HR HPV infection among individuals attending reproductive health clinics at the selected facilities remains common. The study identifies the need for effective implementation and clinical follow-up process of cervical cancer control program in the Lake Victoria Basin.

Significant specificity of TruScreen in cervical cytology of ASC and LSIL women with incomplete cervical transformation zone type during COVID-19 post-pandemic in China: a prospective study (preprint)

Objective: To evaluate the efficacy of TruScreen (TS) detecting cervical intraepithelial neoplasia (CIN) in cytology of atypical squamous cells (ASC) and low-grade squamous intraepithelial lesion (LSIL) women during COVID-19 post-pandemic. Design: Prospective, single-center study. Setting: Changsha, China. Population: ASC and LSIL women from December 2020 to May 2021. Methods: Participants underwent TS, colposcopy examination and biopsy in turn. Diagnostic value of TS, high-risk human papillomavirus (hrHPV) and TS combined with hrHPV were compared. Differences of TS regarding cervical transformation zone (TZ) type and menopause, correlations between TS and p16, Ki-67 were assessed. Main outcome measures: Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and area under curve (AUC) for diagnostic value. Spearman coefficient for correlation. Results: A total of 483 patients were enrolled. Specificity of TS detecting CIN1+, CIN2+, CIN3+ were 77.1% (95% CI, 70.4%-82.7%), 66.7% (95% CI, 61.5%-71.5%), 62.7% (95% CI, 57.8%-67.4%) and all were significantly higher than hrHPV test (P<0.001). TS had a high sensitivity (68.0% vs 52.0%, P>0.05) and significantly higher specificity (70.0% vs 48.5%, P<0.05) and NPV (89.6% vs 73.3%, P<0.05) in women with incomplete cervical TZ type (II and III) than TZ type I in detection of CIN2+. Conclusion: TS is an effective triage screening method for cervical cytology of ASC and LSIL women during COVID-19 post-pandemic, especially for incomplete cervical TZ type women.

Unleashing the Power of Artificial Intelligence: Unraveling the Intricate Dynamics between Viral and Bacterial Infections, Immune Factors, COVID-19, and Cancer in Women's Health (preprint)

The intricate interplay between viral and bacterial infections, immune factors, COVID-19, and cancer in women's health has garnered significant attention in recent research. This comprehensive study aimed to unravel the complex dynamics between these factors and provide valuable insights into their implications for women's health. Through meticulous analysis of available data, this study elucidated the prevalence of viral and bacterial infections in women, encompassing influential pathogens such as influenza, human papillomavirus, Staphylococcus aureus, Escherichia coli, and Streptococcus pneumoniae. Additionally, it explored the relationship between specific cytokine types, including Interleukin-6 (IL-6), Tumor Necrosis Factor-alpha (TNF-α), Interferon-gamma (IFN-γ), and Interleukin-10 (IL-10), and viral infections. The prevalence of various cancer types, such as breast cancer, lung cancer, colorectal cancer, ovarian cancer, and cervical cancer, was also assessed. Furthermore, this study examined the correlations between immune factors and viral infections, uncovering significant associations that shed light on the intricate interplay between immune responses and viral infections. Immune markers such as IL-6, TNF-α, IFN-γ, Interleukin-1beta (IL-1β), and Interleukin-12 (IL-12) exhibited diverse levels of correlation with specific viral infections. These findings hold promise for disease prognosis and treatment optimization. Additionally, the association between bacterial infections and women's health conditions was explored, revealing the impact of pathogens like Staphylococcus aureus, Escherichia coli, Streptococcus pneumoniae, Pseudomonas aeruginosa, and Enterococcus faecalis on gynecological infections, reproductive disorders, and other relevant conditions. This highlights the need for effective strategies to prevent and manage bacterial infections, aiming to mitigate their adverse effects on women's health. In the context of COVID-19, this study investigated immune factors as predictors of disease outcomes in women. Various cytokines, including IL-6, TNF-α, IL-1β, IFN-γ, IL-10, IL-8, IL-4, IL-2, IL-12, and IL-17, demonstrated associations with disease severity, offering potential prognostic markers for identifying individuals at higher risk of severe illness. Furthermore, the relationship between viral and bacterial infections and cancer incidence in women was explored. Viral infections, such as human papillomavirus and influenza, showed associations with specific cancer types, including breast cancer, cervical cancer, lung cancer, skin cancer, and stomach cancer. Bacterial infections, such as Staphylococcus aureus and Escherichia coli, were linked to ovarian cancer, colorectal cancer, pancreatic cancer, bladder cancer, kidney cancer, and esophageal cancer. These findings provide valuable insights into the potential role of infectious etiologies in cancer development among women. In conclusion, this comprehensive study unveils the intricate dynamics between viral and bacterial infections, immune factors, COVID-19, and cancer in women's health. The findings emphasize the importance of considering the interconnectedness of these factors to enhance disease prevention, diagnosis, and treatment strategies in women. Further research is warranted to unravel the underlying mechanisms and translate these findings into clinical applications.

No woman left behind: achieving cervical cancer elimination among women living with HIV.

Cervical cancer is the fourth most common malignancy in women of reproductive age globally. The burden of this disease is highest in low-income and middle-income countries, especially among women living with HIV. In 2018, WHO launched a global strategy to accelerate cervical cancer elimination through rapid scale-up of prophylactic vaccination, cervical screening, and treatment of precancers and cancers. This initiative was key in raising a call for action to address the stark global disparities in cervical cancer burden. However, achieving elimination of cervical cancer among women with HIV requires consideration of biological and social issues affecting this population. This Position Paper shows specific challenges and uncertainties on the way to cervical cancer elimination for women living with HIV and highlights the scarcity of evidence for the effect of interventions in this population. We argue that reaching equity of outcomes for women with HIV will require substantial advances in approaches to HPV vaccination and improved understanding of the long-term effectiveness of HPV vaccines in settings with high HIV burden cervical cancer, just as HIV, is affected by social and structural factors such as poverty, stigma, and gender discrimination, that place the elimination strategy at risk. Global efforts must, therefore, be galvanised to ensure women living with HIV have optimised interventions, given their substantial risk of this preventable malignancy.

Perceived barriers to cervical cancer screening and motivators for at-home human papillomavirus self-sampling during the COVID-19 pandemic: Results from a telephone survey.

Background: Home-based self-sampling for human papillomavirus (HPV) testing may be an alternative for women not attending clinic-based cervical cancer screening. Methods: We assessed barriers to care and motivators to use at-home HPV self-sampling kits during the COVID-19 pandemic as part of a randomized controlled trial evaluating kit effectiveness. Participants were women aged 30-65 and under-screened for cervical cancer in a safety-net healthcare system. We conducted telephone surveys in English/Spanish among a subgroup of trial participants, assessed differences between groups, and determined statistical significance at p<0.05. Results: Over half of 233 survey participants reported that clinic-based screening (Pap) is uncomfortable (67.8%), embarrassing (52.4%), and discomfort seeing male providers (63.1%). The last two factors were significantly more prevalent among Spanish vs English speakers (66.4% vs 30% (p=0.000) and 69.9 vs 52.2% (p=0.006), respectively). Most women who completed the kit found Pap more embarrassing (69.3%), stressful (55.6%), and less convenient (55.6%) than the kit. The first factor was more prevalent among Spanish vs English speakers (79.6% vs 53.38%, p=0.001) and among patients with elementary education or below. Conclusions: The COVID-19 pandemic influenced most (59.5%) to participate in the trial due to fear of COVID, difficulty making appointments, and ease of using kits. HPV self-sampling kits may reduce barriers among under-screened women in a safety-net system.

HPV prevalence and genotype distribution among women in eastern China during the Covid-19 pandemic.

Since March 2020, the pandemic caused by SARS-CoV-2 has affected nearly all aspects of daily life. In this study, we investigated the age-stratified prevalence and genotype distribution of human papillomavirus (HPV) among females in Shandong province (eastern China) and aimed to provide guidance on HPV-based cervical cancer screening and vaccination. The distribution of HPV genotypes was analyzed using PCR-Reverse Dot Hybridization. The overall infection rate of HPV was 16.4%, which was dominated by high-risk genotypes. The most prevalent genotype was HPV16 (2.9%), followed by HPV52 (2.3%), HPV53 (1.8%), HPV58 (1.5%), and HPV51 (1.3%). Among the positive cases with HPV infection, single-genotype infection was significantly higher than that of multi-genotype infection. In subgroup analyses by age (≤25, 26-35, 36-45, 46-55, >55), HPV16, 52, and 53 were consistently the three most common hrHPV genotypes in all age groups. The infection rate of multi-genotypes in the ≤25 and >55 age groups was significantly higher than that in other age groups. A bimodal distribution of HPV infection rate was observed in different age groups. Among lrHPV genotypes, HPV6, HPV11, and HPV81 were the three most common types in the ≤25 age group, while in other age groups, HPV81, HPV42, and HPV43 are the three most common lrHPV genotypes. This study provides basic information on the distribution and genotypes of HPV in the female population in eastern China, which could improve the application of HPV diagnostic probes and vaccines.

Barriers and facilitators of HPV vaccination in sub-saharan Africa: a systematic review.

BACKGROUND: Human Papilloma Virus (HPV) is the most common sexually transmitted infection worldwide. Globally, both men and women have a 50% risk of being infected at least once in their life. HPV prevalence is among the highest in sub-Saharan Africa (SSA), at an average of 24%. HPV causes different types of cancers, including cervical cancer (CC), which is the leading cause of cancer deaths among women in SSA. HPV-vaccination has been proven to be effective in reducing HPV induced cancers. SSA countries are delayed in reaching the WHO's target of fully vaccinating 90% of girls within the age of 15 by 2030. Our systematic review aims to identify barriers and facilitators of HPV-vaccination in SSA to inform national implementation strategies in the region. METHODS: This is a mixed method systematic review based on the PRISMA statement and The Joanna Briggs Institute Reviewers' Manual. Search strategies were adapted to each selected database: PubMed/MEDLINE, Livivo, Google Scholar, Science Direct, and African Journals Online for papers published in English, Italian, German, French and Spanish between 1 December 2011 and 31 December 2021. Zotero and Rayyan were the software used for data management. The appraisal was conducted by three independent reviewers. RESULTS: A total of 20 articles were selected for appraisal from an initial 536 articles. Barriers included: limited health system capacities, socio-economic status, stigma, fear and costs of vaccines, negative experience with vaccinations, COVID-19 pandemic, lack of correct information, health education (HE) and consent. Additionally, we found that boys are scarcely considered for HPV-vaccination by parents and stakeholders. Facilitators included: information and knowledge, policy implementation, positive experience with vaccinations, HE, stakeholders' engagement, women's empowerment, community engagement, seasonality, and target-oriented vaccination campaigns. CONCLUSIONS: This review synthesizes barriers and facilitators of HPV-vaccinations in SSA. Addressing these can contribute to the implementation of more effective HPV immunization programs targeted at eliminating CC in line with the WHO 90/70/90 strategy. REGISTRATION AND FUNDING: Protocol ID: CRD42022338609 registered in the International Prospective Register of Systematic Reviews (PROSPERO).

Interventions to increase cervical screening uptake among immigrant women: A systematic review and meta-analysis.

Numerous intervention studies have attempted to increase cervical screening uptake among immigrant women, nonetheless their screening participation remains low. This systematic review and meta-analysis aimed to summarise the evidence on interventions to improve cervical screening among immigrant women globally and identify their effectiveness. Databases PubMed, EMBASE, Scopus, PsycINFO, ERIC, CINAHL and CENTRAL were systematically searched from inception to October 12, 2021, for intervention studies, including randomised and clinical controlled trials (RCT, CCT) and one and two group pre-post studies. Peer-reviewed studies involving immigrant and refugee women, in community and clinical settings, were eligible. Comparator interventions were usual or minimal care or attention control. Data extraction, quality appraisal and risk of bias were assessed by two authors independently using COVIDENCE software. Narrative synthesis of findings was carried out, with the main outcome measure defined as the cervical screening uptake rate difference pre- and post-intervention followed by random effects meta-analysis of trials and two group pre-post studies, using Comprehensive Meta-Analysis software, to calculate pooled rate ratios and adjustment for publication bias, where found. The protocol followed PRISMA guidelines and was registered prospectively with PROSPERO (CRD42020192341). 1,900 studies were identified, of which 42 (21 RCTS, 4 CCTs, and 16 pre-post studies) with 44,224 participants, were included in the systematic review, and 28 with 35,495 participants in the meta-analysis. Overall, the uptake difference rate for interventions ranged from -6.7 to 96%. Meta-analysis demonstrated a pooled rate ratio of 1.15 (95% CI 1.03-1.29), with high heterogeneity. Culturally sensitive, multicomponent interventions, using different modes of information delivery and self-sampling modality were most promising. Interventions led to at least 15% increase in cervical screening participation among immigrant women. Interventions designed to overcome logistical barriers and use multiple channels to communicate culturally appropriate health promotion messages are most effective at achieving cervical screening uptake among immigrant women.

Relationship between regular cervical cancer screening and social background in Japan during the COVID-19 pandemic (preprint)

Background: Among Organization for Economic Co-operation and Development countries, Japan has one of the lowest cervical cancer screening rates. The cancer screening rate has reportedly worsened with the coronavirus disease of 2019 (COVID-19) pandemic. This study investigated the COVID-19 history and socioeconomic background of people who did not undergo on-time cervical cancer screening (CCS) during the two years of COVID-19-related restrictions in Japan. Methods: We used data from the Japan COVID-19 and Society Internet Survey, a nationwide, internet-based, self-report, cohort observational study conducted in 2022. The outcome variable was identified by asking whether the respondent had undergone on-time CCS within the last two years. This study used multivariate log-binomial regression models to evaluate inequalities during regular checkups for CCS. Adjusted prevalence ratios (APRs) with 95% confidence intervals (CIs) were estimated to incorporate socioeconomic background variables. Results: Of 12,066 respondents, 6469 (53.6%) had yet to undergo CCS within two years. The prevalence ratio (PR) of on-time CCS was 0.70 (95% CI: 0.63–0.79) for those in their 20s and 0.78 (95%CI:0.70-0.87) for those in their 60s, compared to their 40s. Moreover, socioeconomic inequities were found in the following groups: unemployed/student, unmarried, high school graduate or lower, and household income below 4 million yen. PR of on-time CCS with a history of COVID-19, unvaccinated status, or fear of COVID-19 was not significantly different from that of respondents who underwent CCS. However, the PR of those who had not undergone on-time CCS was significantly lower than that of respondents who had undergone breast cancer screening (PR: 0.29, 95% CI: 0.28–0.31). Conclusion: the relationship between socioeconomic inequalities and CCS hesitancy was prevalent among the younger respondents. Our findings will help policymakers identify problems and strategies to improve CCS screening rates in Japan.

Exploring the factors contributing to low vaccination uptake for nationally recommended routine childhood and adolescent vaccines in Kenya.

BACKGROUND: Vaccination remains the most effective means of reducing the burden of infectious disease among children. It is estimated to prevent between two to three million child deaths annually. However, despite being a successful intervention, basic vaccination coverage remains below the target. About 20 million infants are either under or not fully vaccinated, most of whom are in Sub-Saharan Africa region. In Kenya, the coverage is even lower at 83% than the global average of 86%. The objective of this study is to explore the factors that contribute to low demand or vaccine hesitancy for childhood and adolescent vaccines in Kenya. METHODS: The study used qualitative research design. Key Informant Interviews (KII) was used to obtain information from national and county-level key stakeholders. In-depth Interviews (IDI) was done to collect opinions of caregivers of children 0-23 months and adolescent girls eligible for immunization, and Human papillomavirus (HPV) vaccine respectively. The data was collected at the national level and counties such as Kilifi, Turkana, Nairobi and Kitui. The data was analyzed using thematic content approach. A total of 41 national and county-level immunization officials and caregivers formed the sample. RESULTS: Insufficient knowledge about vaccines, vaccine supply issues, frequent healthcare worker's industrial action, poverty, religious beliefs, inadequate vaccination campaigns, distance to vaccination centers, were identified as factors driving low demand or vaccine hesitancy against routine childhood immunization. While factors driving low uptake of the newly introduced HPV vaccine were reported to include misinformation about the vaccine, rumors that the vaccine is a form of female contraception, the suspicion that the vaccine is free and available only to girls, poor knowledge of cervical cancer and benefits of HPV vaccine. CONCLUSIONS: Rural community sensitization on both routine childhood immunization and HPV vaccine should be key activities post COVID-19 pandemic. Likewise, the use of mainstream and social media outreaches, and vaccine champions could help reduce vaccine hesitancy. The findings are invaluable for informing design of context-specific interventions by national and county-level immunization stakeholders. Further studies on the relationship between attitude towards new vaccines and connection to vaccine hesitancy is necessary.

Patterns of HPV vaccine hesitancy among catch-up generations in Japan: A descriptive study.

BACKGROUND: Cervical cancer is a preventable disease caused by human papillomavirus (HPV). The HPV vaccine uptake in Japan has been slow since the Ministry of Health, Labour and Welfare suspended the recommendation for proactive HPV vaccination in 2013. In April 2022, Japan initiated catch-up vaccinations for women who missed the opportunity to receive the HPV vaccine. However, as of September 2022, very few women had received catch-up vaccination, raising concerns about vaccine hesitancy in the target population. It is necessary to understand the thinking and motivation of the target population to develop effective strategies to improve vaccination rates. Therefore, using cluster analysis, this study aimed to clarify the pattern of HPV vaccine hesitancy among the catch-up generations in Japan. METHODS: This descriptive study was based on an Internet survey completed by 3,790 women in Japan aged over 18 years who were eligible for catch-up vaccination and had not yet received an HPV vaccine. Participants were asked about their intention and thinking about the HPV vaccine and descriptive norms on vaccination intention. Cluster analysis using k-means clustering was performed to clarify these patterns. RESULTS: Cluster analysis revealed three hesitancy patterns: acceptance, neutral and refusal. The acceptance group, with high intention, comprised 28.2% of the participants, and students and a high-income level mainly dominated this group. The refusal group, with negative thinking and low intention, accounted for 20.1% and was more prevalent among workers and the unemployed. The neutral group, with neutral thinking and intention, accounted for 51.6%. The perceived effect of descriptive norms on vaccination intention was large in the acceptance group but small in the refusal group. CONCLUSION: HPV vaccine awareness promotion strategies must be based on the characteristics of each group and the different distributions of sociodemographic factors.

COVID-19 as a catalyst for reimagining cervical cancer prevention.

Cervical cancer has killed millions of women over the past decade. In 2019 the World Health Organization launched the Cervical Cancer Elimination Strategy, which included ambitious targets for vaccination, screening, and treatment. The COVID-19 pandemic disrupted progress on the strategy, but lessons learned during the pandemic - especially in vaccination, self-administered testing, and coordinated mobilization on a global scale - may help with efforts to achieve its targets. However, we must also learn from the failure of the COVID-19 response to include adequate representation of global voices. Efforts to eliminate cervical cancer will only succeed if those countries most affected are involved from the very start of planning. In this article we summarize innovations and highlight missed opportunities in the COVID response, and make recommendations to leverage the COVID experience to accelerate the elimination of cervical cancer globally.

Quantification of impact of COVID-19 pandemic on cancer screening programmes - a case study from Argentina, Bangladesh, Colombia, Morocco, Sri Lanka, and Thailand.

It is quite well documented that the COVID-19 pandemic disrupted cancer screening services in all countries, irrespective of their resources and healthcare settings. While quantitative estimates on reduction in volume of screening tests or diagnostic evaluation are readily available from the high-income countries, very little data are available from the low- and middle-income countries (LMICs). From the CanScreen5 global cancer screening data repository we identified six LMICs through purposive sampling based on the availability of cancer screening data at least for the years 2019 and 2020. These countries represented those in high human development index (HDI) categories (Argentina, Colombia, Sri Lanka, and Thailand) and medium HDI categories (Bangladesh and Morocco). No data were available from low HDI countries to perform similar analysis. The reduction in the volume of tests in 2020 compared to the previous year ranged from 14.1% in Bangladesh to 72.9% in Argentina (regional programme) for cervical screening, from 14.2% in Bangladesh to 49.4% in Morocco for breast cancer screening and 30.7% in Thailand for colorectal cancer screening. Number of colposcopies was reduced in 2020 compared to previous year by 88.9% in Argentina, 38.2% in Colombia, 27.4% in Bangladesh, and 52.2% in Morocco. The reduction in detection rates of CIN 2 or worse lesions ranged from 20.7% in Morocco to 45.4% in Argentina. Reduction of breast cancer detection by 19.1% was reported from Morocco. No association of the impact of pandemic could be seen with HDI categories. Quantifying the impact of service disruptions in screening and diagnostic tests will allow the programmes to strategize how to ramp up services to clear the backlogs in screening and more crucially in further evaluation of screen positives. The data can be used to estimate the impact on stage distribution and avoidable mortality from these common cancers.

Updated Review of Major Cancer Risk Factors and Screening Test use in the United States, with a Focus on Changes During the COVID-19 Pandemic.

We present national and state representative prevalence estimates of modifiable cancer risk factors, preventive behaviors and services, and screening, with a focus on changes during the COVID-19 pandemic. Between 2019 and 2021, current smoking, physical inactivity, and heavy alcohol consumption declined, and human papillomavirus vaccination and stool testing for colorectal cancer screening uptake increased. In contrast, obesity prevalence increased, while fruit consumption and cervical cancer screening declined during the same timeframe. Favorable and unfavorable trends were evident during the second year of the COVID-19 pandemic that must be monitored as more years of consistent data are collected. Yet disparities by racial/ethnic and socioeconomic status persisted, highlighting the continued need for interventions to address suboptimal levels among these population subgroups.

Coverage of cervical cancer screening in Uruguay, 2018 / Cobertura de tamizaje de cáncer de cuello de útero en Uruguay, 2018 / Cobertura do rastreamento do câncer do colo do útero no Uruguai, 2018

Introducción: el cáncer de cuello uterino (CCU) causa una significativa pérdida de años por discapacidad y muerte prematura en el mundo. Se relaciona fuertemente, por su etiología, a las inequidades socioeconómicas. Alcanzar una cobertura del 80% del tamizaje poblacional a través de la colpocitología oncológica constituye una de las principales estrategias para disminuir la morbimortalidad por este cáncer. Objetivos: describir la cobertura de tamizaje en CCU de las mujeres de 21 a 64 años, usuarias del Sistema Nacional Integrado de Salud (SNIS) de Uruguay en el año 2018 y explorar su comportamiento según edad, lugar de residencia, características socioeconómicas y culturales del territorio. Métodos: estudio descriptivo, en base a fuentes de datos secundarios, con una muestra que alcanzó el 95% del universo. La técnica de tamizaje considerada fue la colpocitología oncológica de (PAP) con vigencia de hasta 3 años al 30/9/2018. Resultados: la cobertura de tamizaje en CCU en 2018 fue del 57%, siendo menor en las primeras y últimas edades consideradas, variando por zona geográfica, encontrándose menor porcentaje de PAP vigente en las mujeres residentes en departamentos con menores índices de desarrollo humano y con mayor porcentaje de hogares por debajo de la línea de pobreza. Conclusiones: la cobertura de tamizaje en CCU en Uruguay debe aumentar para disminuir la morbimortalidad por este cáncer. Se requiere implementar acciones para reducir la heterogeneidad entre edades y departamentos de residencia. Esta estimación constituye una línea de base que permite comparar la situación país pospandemia COVID-19 replicando la misma metodología.

Summary: Introduction: cervical cancer causes a significant loss of years due to disabilities and early deaths around the world. Due to its etiology, it is closely linked to socio- economic inequalities. Cervical cancer screening coverage of 80 % of the population through and pap smear constitutes one of the main strategies to reduce morbimortality of this kind of cancer. Objectives: to describe cervical cancer screening coverage in women between 21 and 64 years old, users of the National Integrated Health System (SNIS) in Uruguay in 2018 and explore their behavior according to age, place of residence, socio-economic and territorial cultural characteristics. Method: descriptive study, based on secondary data sources of a sample representing 95% of the universe. The screening technique considered in the study was a pap smear, valid for up to three years on September 30, 2019. Results: cervical cancer screening coverage in 2018 was 57%, lower in the first and last ages considered and it varied depending on the geographical area. A lower percentage of valid smear tests was found in women who were residents of provinces with lower human development index and a higher percentage of homes below the poverty line. Conclusions: cervical cancer screening coverage in Uruugay needs to increase in order to reduce morbimortality. The implementation of actions aimed at reducing differences between ages and places of residence is required. This estimation may be taken as a baseline that allows for a comparison with the post-COVID 19 pandemic situation, by replicating the same method.

Introdução: o câncer do colo do útero (CCU), causa uma perda significativa de anos por incapacidade e morte prematura no mundo estando fortemente relacionada, por sua etiologia, às iniquidades socioeconômicas. Uma das principais estratégias para reduzir a morbimortalidade por esse câncer é alcançar 80% de cobertura de rastreamento populacional por meio da colpocitologia oncológica. Objetivos: descrever a cobertura do rastreamento do CCU em mulheres de 21 a 64 anos, usuárias do Sistema Nacional Integrado de Saúde (SNIS) do Uruguai em 2018 e analisar seu comportamento de acordo com idade, local de residência, características socioeconômicas e culturais do território. Métodos: estudo descritivo, baseado em fontes de dados secundárias de uma amostra que atingiu 95% do universo. A técnica de rastreamento considerada foi a colpocitologia oncológica (PAP) válida por até 3 anos a partir de 30/09/2018. Resultados: a cobertura de rastreamento no CCU em 2018 foi de 57%, sendo menor nas primeiras e últimas idades consideradas, variando por área geográfica, encontrando menor percentual de PAP atual em mulheres residentes em departamentos com menores índices de desenvolvimento humano e com maior percentual de famílias abaixo da linha de pobreza. Conclusões: deve-se aumentar a cobertura de rastreamento no CCU no Uruguai para reduzir a morbimortalidade por esse câncer. É necessário implementar ações para reduzir a heterogeneidade entre idades e departamentos de residência. Essa estimativa constitui uma linha de base que permite comparar a situação do país pós-pandemia por COVID-19, replicando a mesma metodologia.

The impact of COVID-19 on screening for colorectal, gastric, breast, and cervical cancer in Korea.

OBJECTIVES: The coronavirus disease 2019 (COVID-19) pandemic has affected the utilization of healthcare services, including participation in cancer screening programs. We compared cancer screening participation rates for colorectal, gastric, breast, and cervical cancers among participants in the National Cancer Screening Program (NCSP) in 2019 and 2020 to address the potential distraction effect of COVID-19 on cancer screening. METHODS: Data from the NCSP for 4 cancer types (stomach, colorectal, breast, and cervical) in 2019 and 2020 were used to calculate cancer screening participation rates by calendar month, gender, age group, and geographical region. Monthly participation rates were analyzed per 1,000 eligible individuals. RESULTS: The screening participation rate decreased in 2020 compared to 2019 for all 4 cancers: colorectal (40.5 vs. 35.3%), gastric (61.9 vs. 54.6%), breast (63.8 vs. 55.8%), and cervical (57.8 vs. 52.2%) cancers. Following 2 major COVID-19 waves in March and December 2020, the participation rates in the 4 types of cancer screening dropped compared with those in 2019. The highest decline was observed in the elderly population aged 80 years and older (percentage change: -21% for colorectal cancer; -20% for gastric cancer; -26% for breast cancer; -20% for cervical cancer). CONCLUSIONS: After the 2 major COVID-19 waves, the screening participation rate for 4 types of cancer declined compared with 2019. Further studies are needed to identify the indirect effects of the COVID-19 pandemic on cancer patients, such as delayed diagnoses of cancer or excess cancer deaths.

Frequency of human papilomavirus and associated factors in gypsy and quilombola women : Human papillomavirus in gypsy and quilombola women.

BACKGROUND: The prevalence of Human Papillomavirus (HPV) infection in the general population is widely known, however, there are still few studies related to this infection in minority groups, Thus, the objective is to analyze the frequency of human papillomavirus and associated factors in quilombola and gypsy women. METHODS: Cross-sectional research with 145 quilombola and gypsy women from Caxias, Maranhão. Two Pap smear collections were performed and a questionnaire with 46 questions was applied between January, 2020 and March, 2021. Descriptive analysis and Odds Ratio with 95% confidence interval were performed. The research was approved by the ethics committee. RESULTS: There were 09 cases of atypia. The frequency of human papillomavirus was 41.37%, with a higher risk in quilombolas 55 (91.70%). Multiple infections were prevalent (53%) with high-risk genotypes 21 (35%). Types 16 and 18 together accounted for 42.85% of cases. CONCLUSIONS: The frequency of human papillomavirus infection was higher than those recorded in the Northeast and Brazil, and therefore type 16 predominated. Due to limitations, the virus lineages and sublineages were not evaluated. Quilombola women had a higher rate of infection than gypsies.

Cancer-related knowledge, beliefs, and behaviors among Hispanic/Latino residents of Indiana.

BACKGROUND: Cancer is the leading cause of death for Hispanics in the USA. Screening and prevention reduce cancer morbidity and mortality. METHODS: This study administered a cross-sectional web-based survey to self-identified Hispanic residents in the state of Indiana to assess their cancer-related knowledge, beliefs, and behaviors, as well as to identify what factors might be associated with cancer screening and prevention. Chi-square and Fisher's exact test were used to compare associations and logistic regression used to develop both univariate and multivariate regression models. RESULTS: A total of 1520 surveys were completed, median age of respondents was 53, 52% identified as men, 50.9% completed the survey in Spanish, and 60.4% identified the USA as their country of birth. Most were not able to accurately identify ages to begin screening for breast, colorectal, or lung cancer, and there were significant differences in cancer knowledge by education level. US-born individuals with higher income and education more often believed they were likely to develop cancer and worry about getting cancer. Sixty eight percent of respondents were up-to-date with colorectal, 44% with breast, and 61% with cervical cancer screening. Multivariate models showed that higher education, lack of fatalism, older age, lower household income, and unmarried status were associated with cervical cancer screening adherence. CONCLUSIONS: Among a Hispanic population in the state of Indiana, factors associated with cervical cancer screening adherence were similar to the general population, with the exceptions of income and marital status. Younger Hispanic individuals were more likely to be adherent with breast and colorectal cancer screening, and given the higher incidence of cancer among older individuals, these results should guide future research and targeted outreach.
