ABSTRACT
Background: Socioeconomic conditions are strongly associated with breast and cervical cancer incidence and mortality patterns; therefore, social protection programmes (SPPs) might impact these cancers. This study aimed to evaluate the effect of SPPs on breast and cervical cancer outcomes and their risk/protective factors. Methods: Five databases were searched for articles that assessed participation in PPS and the incidence, survival, mortality (primary outcomes), screening, staging at diagnosis and risk/protective factors (secondary outcomes) for these cancers. Only peer-reviewed quantitative studies of women receiving SPPs compared to eligible women not receiving benefits were included. Independent reviewers selected articles, assessed eligibility, extracted data, and assessed the risk of bias. A harvest plot represents the included studies and shows the direction of effect, sample size and risk of bias. Findings: Of 17,080 documents retrieved, 43 studies were included in the review. No studies evaluated the primary outcomes. They all examined the relationship between SPPs and screening, as well as risk and protective factors. The harvest plot showed that in lower risk of bias studies, participants of SPPs had lower weight and fertility, were older at sexual debut, and breastfed their infants for longer. Interpretation: No studies have yet assessed the effect of SPPs on breast and cervical cancer incidence, survival, or mortality; nevertheless, the existing evidence suggests positive impacts on risk and protective factors.
ABSTRACT
OBJECTIVE: Survival outcomes of robotic radical hysterectomy (RRH) remain controversial. Therefore, we performed a meta-analysis to evaluate survival outcomes between RRH) and laparoscopic radical hysterectomy (LRH) in patients with early-stage cervical cancer. METHODS: Studies comparing between RRH and LRH published up to November 2022 were systemically searched in the PubMed, Cochrane Library, Web of Science, ScienceDirect, and Google Scholar databases. Manual searches of related articles and relevant bibliographies of the published studies were also performed. Two researchers independently extracted data. Studies with information on recurrence and death after minimally invasive radical hysterectomy were also included. The extracted data were analyzed using the Stata MP software package version 17.0. RESULTS: Twenty eligible clinical trials were included in the meta-analysis. When all studies were pooled, the odds ratios of RRH for recurrence and death were 1.19 (95% confidence interval [CI]=0.91-1.55; p=0.613; I²=0.0%) and 0.96 (95% CI=0.65-1.42; p=0.558; I²=0.0%), respectively. In a subgroup analysis, the quality of study methodology, study size, country where the study was conducted, and publication year were not associated with survival outcomes between RRH and LRH. CONCLUSION: This meta-analysis demonstrates that the survival outcomes are comparable between RRH and LRH.

Objective To investigate the expression and significance of cyclin dependent kinase inhibitor 3(CDKN3)in human papillomavirus type 16(HPV16)-positive cervical cancer.Methods CDKN3 expression in pan-cancer was retrieved and downloaded from the Gene Expression Profiling Interactive Analysis(GEPIA)platform,and the expression levels of CDKN3 between normal cervical tissues(13 samples)and cervical cancer tissues(306 samples)were compared.Subsequently,GSE39001 data of HPV16-positive cervical cancer was sourced and downloaded from the Gene Expression Omnibus(GEO)database,and the expression levels of CDKN3 mRNA in HPV16-positive cervical cancer tissues(43 samples)and normal cervical tissues(12 samples)were compared.Immunohistochemical method was used to detect the expression of CDKN3 in 12 ca-ses of HPV16-positive cervical cancer,12 cases of HPV16-positive cervical precancerous lesions,10 cases of HPV16-positive chronic cervicitis and 7 cases of HPV-negative normal cervical samples collected from the Af-filiated Hospital of Guizhou Medical University.SiHa(HPV16-positive),HeLa(HPV18-positive)and HCC94(HPV-negative)cervical cancer cell lines were selected,and their CDKN3 expression were detected by West-ern blot.Results The GEPIA platform analysis showed that CDKN3 was highly expressed in pan-cancer,and the expression level of CDKN3 in cervical cancer tissue was significantly higher than that in normal cervical tissue(P<0.05).The GEO dataset reflected a significantly increased CDKN3 mRNA expression level in HPV16-positive cervical cancer compared to normal cervical tissue(P<0.001).Immunohistochemical verifi-cation showed that the positive expression rates of CDKN3 in HPV16-positive cervical cancer,HPV16-positive cervical precancerous lesion,HPV16-positive chronic cervicitis and HPV-negative normal cervical tissues were 91.7%,58.3%,0 and 0,respectively.Western blot analysis of cervical cancer cells showed that the expression level of CDKN3 in SiHa(HPV16-positive)cells was significantly higher than that in HeLa(HPV18-positive)and HCC94(HPV-negative)cells(P<0.05).Conclusion CDKN3 is a new oncogene of HPV16-positive cer-vical cancer,which may be used as a marker of cervical precancerous lesions and cervical cancer screening,and may provide a theoretical basis for subsequent mechanism research and targeted therapy.
ABSTRACT
Background: The high prevalence of cervical cancer in developing countries, despite its preventive nature, makes the disease a principal matter of concern for scientific studies. Providing global availability of primary and secondary preventive methods based on the high-risk human papillomavirus (HPV), which is the well-known pathogenesis in most malignant cervical lesions, has become the World Health Organization's (WHO's) critical target for 2030. Considering the demographic diversity and manufacturing of the internal vaccine in Iran, there is need for more study on the cost-effectiveness of these strategies. Materials and Methods: This study intends to assess female HPV prevalence at the time in Iran provinces, especially in the capital province, Khorasan Razavi, in the north to establish a scientific rationale for conducting further studies on arguments for and against national HPV prevention strategies in line with the WHO. In this population-based study, the HPV prevalence was evaluated in 900 cervical samples accumulated between 2012 and 2015. The data were later compared with recently published data in the same province, in the north of Iran. Result: Based on the results of our cross-sectional study, the estimated prevalence of HPV infection in the northern female population was 4.1% in 2015 and significantly increased to 35% in 2021. Conclusion: The hypothesis of the impact of behavioral and cultural changes in addition to population aging on general health indicates the need for national health promotion strategies. Additionally, it emphasizes the critical significance of conducting further investigational studies to obtain the actual and updated prevalence of HPV in Iran.
ABSTRACT
Background: Worldwide, about 20-25 million people are affected by sickle cell disease (SCD), with 60% of patients living in sub-Saharan Africa. Despite recent therapeutic advancements resulting in improved life expectancy among SCD patients, the prevalence of high-risk human papillomavirus (hr-HPV) and cervical lesions have not been studied in women with SCD. We determined the prevalence of hr-HPV and cervical lesions among women with SCD and recommended strategies for reducing cervical cancer incidence in this cohort. Methods: Through the mPharma 10,000 Women Initiative, women with SCD attending routine visits at the Ghana Institute of Clinical Genetics SCD clinic were screened by trained nurses. Screening was performed via concurrent MA-6000 hr-HPV DNA testing and enhanced visual assessment (EVA) mobile colposcopy from mobileODT. Results: Among 168 participants screened (mean age, 43.0 years), the overall prevalence rates of hr-HPV infection and cervical lesions were 28.6% (95% CI, 21.7-35.4) and 3.6% (95% CI, 0.8-6.4), respectively. The hr-HPV prevalence rates stratified by haemoglobin genotype were 29.4% (95% CI, 19.7-39.1) and 28.6% (95% CI, 18.5-38.7) for genotypes SS and SC, respectively. None of the five women with the SF genotype tested hr-HPV positive, and the only patient with Sbthal genotype tested hr-HPV positive. Two women were EVA 'positive' but hr-HPV negative, whereas four were EVA positive and hr-HPV positive. Exploratory analysis revealed no significant associations between hr-HPV positivity and age, education level, marital status or parity. Conclusion: In the absence of a comprehensive national cervical screening programme aimed at including women with SCD as a special population, cervical cancer may increase in frequency among SCD patients. Thus, there is a need to build capacity and expand the scope of screening services for women with SCD.
ABSTRACT
BACKGROUND: Human immunodeficiency virus- positive women have an increased risk of precancerous lesions and invasive cervical cancer. This study aims to identify the level of awareness/knowledge and attitudes toward cervical cancer among women living with Human immunodeficiency virus in the region of Souss-Massa in southern Morocco. Methods: This is a multicenter cross-sectional study conducted in the Souss-Massa region (southern Morocco) among women attending Human immunodeficiency virus treatment and care centers between March 2022 and September 2022. A questionnaire was used for data collection. The Chi-square test and logistic regression were deployed to identify factors associated with cervical cancer awareness among the target population. RESULTS: A total of 494 respondents to the questionnaire, 440 (89.1%) are aware of cervical cancer. Nevertheless, 405 (82.0%) and 369 (74.7%) were unaware of cervical cancer risk factors and symptoms, respectively. Only 125 (25.3%) knew the exact frequency of cervical cancer screening among Human immunodeficiency virus positive women, whereas 221 (44.7%) had ever been tested for cervical cancer. Factors associated with women's awareness of cervical cancer are as follows: level of education (adjusted Odds Ratio = 3.78 with 95% CI, 1.23-11.65), time since diagnosis of Human immunodeficiency virus (adjusted Odds Ratio = 4.31 with 95% CI, 1.12- 16.52), knowledge of women with cervical cancer (adjusted Odds Ratio = 6.30 with 95% CI, 1.87-21.18) and heard the pap- smear/visual inspection with acetic acid (adjusted Odds Ratio = 4.92 with 95% CI, 2.35-10.33). CONCLUSION: The general knowledge of seropositive women regarding cervical cancer remains very low, which justifies the integration of cervical cancer prevention services with Human immunodeficiency virus care, and pinpoints the crucial role of patient education.

AIM: Evidence showed self-efficacy was relevant to rural females' cervical cancer screening behaviour. However, little is known about sources of self-efficacy in cervical cancer screening among rural females. This study aimed to explore sources of self-efficacy in cervical cancer screening among rural females. DESIGN: A qualitative descriptive study was conducted. Both users and providers of cervical cancer screening services in rural areas of China were recruited through maximum variation sampling. METHODS: Individual semi-structured interviews through telephone calls were conducted. Data were analysed via six main stages of the framework method, with the social cognitive theory as a reference. RESULTS: Four main sources were identified, including personal screening experience, hearing about other women's screening experiences, professional health education and consultation, and emotional status. Personal screening experience included enactive mastery of completing the screening behaviour and cognitive mastery of internalisation of the screening. Only the experience of completing cervical cancer screening behaviour was not strong enough to improve self-efficacy. Cognitive mastery showed more critical influence. CONCLUSION: These four sources of rural females' cervical cancer screening self-efficacy matched with the major sources of self-efficacy of the social cognitive theory. Cognition was critical to influencing the screening self-efficacy. Intervention strategies aimed at enhancing rural females' cervical cancer screening self-efficacy can be developed from these four major sources. PUBLIC CONTRIBUTION: A registered nurse with rich experience in cervical cancer-related research and qualitative study was the interviewer of this study. Rural females and cervical cancer screening services providers (healthcare professionals and village staff) were recruited as interviewees. The interview guides were developed by the research team and evaluated by an expert panel including two nurse leaders of gynaecological cancer, one doctor specialised in cervical cancer, and one medical director in a local rural hospital.

AIM: Uterine cervical cancer (UCC) is the fourth most common cancer in women, responsible for more than 300 000 deaths worldwide. Its early detection, by cervical cytology, and prevention, by vaccinating against human papilloma virus, greatly contribute to reducing cervical cancer mortality in women. However, penetration of the effective prevention of UCC in Japan remains low. Plasma metabolome analysis is widely used for biomarker discovery and the identification of cancer-specific metabolic pathways. Here, we aimed to identify predictive biomarkers for the diagnosis and radiation sensitivity of UCC using wide-targeted plasma metabolomics. METHODS: We analyzed 628 metabolites in plasma samples obtained from 45 patients with UCC using ultra-high-performance liquid chromatography with tandem mass spectrometry. RESULTS: The levels of 47 metabolites were significantly increased and those of 75 metabolites were significantly decreased in patients with UCC relative to healthy controls. Increased levels of arginine and ceramides, and decreased levels of tryptophan, ornithine, glycosylceramides, lysophosphatidylcholine, and phosphatidylcholine were characteristic of patients with UCC. Comparison of metabolite profiles in groups susceptible and non-susceptible to radiation therapy, a treatment for UCC, revealed marked variations in polyunsaturated fatty acid, nucleic acid, and arginine metabolism in the group not susceptible to treatment. CONCLUSIONS: Our findings suggest that the metabolite profile of patients with UCC may be an important indicator for distinguishing these patients from healthy cohorts, and may also be useful for predicting sensitivity to radiotherapy.

Background: Cervical cancer (CC) is the third most commonly diagnosed cancer and the fourth leading cause of cancer death in females worldwide, associated with the incidence of human papillomavirus (HPV) infection. The CC incidence is low in Iran, ranking 11th among cancers. This study aimed to estimate the survival rate of CC and the reasons for its low survival rate based on the data retrieved from the Iranian National Cancer Registry System. Methods: In this retrospective cohort study, data for patients diagnosed with CC from 2008 to 2014 were collected and analyzed. The Kaplan-Meier method was used for survival analysis based on epidemiological and clinical factors. Results: A total of 5,304 women were diagnosed from March 10, 2008 to March 9, 2014 and 2,423 patients were followed. The mean age of the cases was 51.91 years, and 65.91% were alive. The 5- and 10-year survival rates were 58% and 50%, respectively, with no difference between younger cases with SCC or AC but better survival rates for older patients with SCC. Conclusions: As a preventable disease, CC is related to biological factors and geographical and sociodemographic indices. Geographical, cultural, and religious behaviors affect the CC incidence and survival. In Iran, the 5-year survival rate ranges from 34% to 70% among different geographic regions. Hence, effective screening based on cultural and sociodemographic issues is recommended.
ABSTRACT
In the Laparoscopic Approach to Cervical Cancer trial, minimally invasive surgery (MIS) has been associated with significantly lower disease-free survival and overall survival rates. The proposed reasons for the increased recurrence and mortality associated with MIS are uterine manipulation, the effect of insufflation gas (CO2), and intracorporeal colpotomy. We applied 2 techniques during surgery to reduce tumor spillage in laparoscopic radical hysterectomy (LRH), which included avoiding using a uterine manipulator and containing the colpotomy using an endoscopic stapler. We aimed to introduce an easy and comfortable traction method with tagged uterine sutures instead of a manipulator or vaginal tube for minimally invasive radical hysterectomy (RH). The patient underwent LRH. After entering the peritoneal cavity, tubal ligation was performed with an endoscopic clip to prevent tumor spillage via the fallopian tubes. Then, the uterine fundus was tied with needle-straightened multifilament Vicryl 2-0, and the tagged uterus was manipulated. Thereafter, pelvic lymphadenectomy was performed before RH. Thereafter, we performed intracorporeal colpotomy by resecting the vagina twice using an endoscopic stapler. Finally, the stapled vaginal stump was resected to retrieve the specimen via the vaginal opening using monopolar scissors after the vagina was washed several times with sterile water. After removing the specimen, the vaginal stump was endoscopically closed with a barbed suture. LRH can be feasibly performed in patients with uterine cervical neoplasm by retracting tagged uterine sutures without the use of a uterine manipulator.

Introduction: The COVID-19 pandemic disrupted the preventive services for cervical cancer (CC) control programs in Mexico, which will result in increased mortality. This study aims to assess the impact of the pandemic on the interruption of three preventive actions in the CC prevention program in Mexico. Methods: This study is a retrospective time series analysis based on administrative records for the uninsured population served by the Mexican Ministry of Health. Patient data were retrieved from the outpatient service information system and the hospital discharge database for the period 2017-2021. Data were aggregated by month, distinguishing a pre-pandemic and a pandemic period, considering April 2020 as the start date of the pandemic. A Poisson time series analysis was used to model seasonal and secular trends. Five process indicators were selected to assess the disruption of the CC program, these were analyzed as monthly data (N=39 pre-pandemic, N=21 during the pandemic). HPV vaccination indicators (number of doses and coverage) and diagnostic characteristics of CC cases were analyzed descriptively. The time elapsed between diagnosis and treatment initiation in CC cases was modeled using restricted cubic splines from robust regression. Results: Annual HPV vaccination coverage declined dramatically after 2019 and was almost null in 2021. The number of positive Papanicolaou smears decreased by 67.8% (90%CI: -72.3, -61.7) in April-December 2020, compared to their expected values without the pandemic. The immediate pandemic shock (April 2020) in the number of first-time and recurrent colposcopies was -80.5% (95%CI:-83.5, -77.0) and -77.9% (95%CI: -81.0, -74.4), respectively. An increasing trend was observed in the proportion of advanced stage and metastatic CC cases. The fraction of CC cases that did not receive medical treatment or surgery increased, as well as CC cases that received late treatment after diagnosis. Conclusions: Our analyses show significant impact of the COVID-19 pandemic with declines at all levels of CC prevention and increasing inequalities. The restarting of the preventive programs against CC in Mexico offers an opportunity to put in place actions to reduce the disparities in the burden of disease between socioeconomic levels.
ABSTRACT
Introduction: Human Papillomavirus (HPV) infection is the most common sexually transmitted infection in women. About 80% of sexually active women will have contact with this virus at some age in their lives. Most infections will be transient, but when the infection becomes persistent, associated with high oncogenic risk HPV, there may be progression to cancer, especially cervical cancer. The best way to prevent HPV infection is through the use of vaccines. Objective: To assess which are the most prevalent types of HPV in the city of Florianópolis, Brazil and if the majority of the diagnosed types are contained in the HPV vaccines currently available on the market and in the public health sector. Methods: More than 14,727 HPV tests were evaluated for the diagnosis of genital HPV infection in women from Florianópolis. The prevalence of infection was evaluated according to age of the women. HPV detection was performed using molecular biology tests, such as hybrid capture (for diagnosis of the HPV group, high or low oncogenic risk) and PCR (viral genotyping) techniques. Results: The diagnosis of HPV infection was made for women between one and 102 years of age. The highest positivity of the exams was observed in women aged 2025 years (51% of the exams). The most prevalent age group was 3135 years old (23.5%), and the lowest was for women aged 70 and above (0.6%). High oncogenic risk HPV was detected in 94.1% of positive samples and was the most frequent in all age groups. Mixed infection (high- and low-risk HPV) was more prevalent in the 6670 age group (25.6%). The most frequent genotypes were non-16/18 high oncogenic risk HPV (77% of positive cases). HPV 16 was found in 17.1% of positive cases, and HPV 18 in 6.5%. Conclusion: The most prevalent types of HPV in Florianópolis in the last 6 years are non-16/18 high oncogenic risk HPV types, viral types not covered by the current HPV vaccine available in the public health sector in Brazil.
Introdução: A infecção pelo Papilomavírus Humano (HPV)é a infecção sexualmente transmissível mais frequente na mulher. Cerca de 80% das mulheres sexualmente ativas irão entrar em contato com este vírus em algum momento da sua vida. A maioria das infecções será transitória, mas quando a infecção se torna persistente, associada aos HPV de alto risco oncogênico, poderá haver a progressão para o câncer, principalmente o câncer de colo de útero. A melhor forma de prevenção da contaminação pelo HPV é através da utilização das vacinas. Objetivo: Avaliar quais são os tipos de HPV mais prevalentes na cidade de Florianópolis, Brasil, e se a maioria dos tipos diagnosticados estão contidos nas vacinas contra o HPV atualmente disponíveis no mercado e no setor público de saúde. Métodos: Foram avaliados 14.727 exames para diagnóstico da infecção genital pelo HPV em mulheres de Florianópolis, de acordo com a idade das mulheres. A detecção do HPV foi realizada através dos exames de biologia molecular pelas técnicas de captura híbrida (para diagnóstico do grupo de HPV, alto ou baixo risco oncogênico) e PCR (genotipagem viral). Resultados: Foram avaliados exames para diagnóstico da infecção de mulheres entre um e 102 anos de idade. A maior positividade dos exames foi observada em mulheres dos 2025 anos (51% dos exames). A faixa etária de maior prevalência foi dos 3135 anos (23,5%), e a menor, após os 70 anos (0,6%). O HPV de alto risco oncogênico foi detectado em 94,1% dos casos positivos e foi o mais frequente em todas as faixas etárias. A infecção mista (HPV de alto e baixo risco) foi mais prevalente na faixa etária dos 6670 anos (25,6%). Os genótipos mais frequentes foram os HPV de alto risco oncogênico não 16/18 (77% dos casos positivos). O HPV 16 foi encontrado em 17,1% dos casos positivos, e o HPV 18 em 6,5%. Conclusão: Os tipos de HPV mais prevalentes em Florianópolis nos últimos 6 anos são os HPV de alto risco oncogênico não 16/18, tipos virais não cobertos pela atual vacina contra o HPV disponível no setor público de saúde do Brasil.Palavras-chave: HPV.

BACKGROUND: Decision aids have been shown to be effective in assisting the decision-making process in healthcare settings. This study aimed to examine the feasibility and acceptability of a linguistically appropriate printed decision aid for cervical cancer screening in South Asian women and to preliminarily estimate its effects on decisional conflicts, clarity of values, risk perception, the screening decision and screening uptake. METHODS: This was a pilot randomised controlled trial. Forty-eight South Asian women aged 25 to 64 years were recruited and allocated to either the intervention group or control group. The participants in the intervention group read a linguistically appropriate printed decision aid. RESULTS: All of the participants in the intervention group agreed that the decision aid was useful in aiding their decision-making. These participants showed significantly greater improvement in decisional conflicts, clarity of values and risk perceptions than those in the control group (all p < 0.05). The screening uptake rate was significantly higher in the intervention group than in the control group (p < 0.001). CONCLUSIONS: The decision aid was feasible and acceptable among South Asian women, and it resulted in reduced decisional conflict and increased screening uptake compared with usual care. To improve the convenience of using decision aids, they could be developed in various forms, such as printed and mobile application forms, to meet individual requirements. TRIAL REGISTRATION: The trial was registered at the Chinese Clinical Trial Registry on 23 October 2021 (ChiCTR2100052225).

Background: Cervical precancer screening in low-resource settings is largely opportunistic with low coverage. Many women in these settings, where the burden of cervical cancer is highest, only visit health institutions when pregnant or after delivery. We explored screening during antenatal and postnatal visits aimed at increasing coverage. Methods: Pregnant women (in any trimester) attending antenatal care (ANC) and women attending postnatal care (PNC; 6-10 weeks) clinics were screened at Catholic Hospital, Battor and at outreach clinics from February to August 2022 (08/02/2022 to 02/08/2022). At the same visit, cervical specimens were obtained for high-risk human papillomavirus (hr-HPV) DNA testing (with the Sansure MA-6000 PCR platform) followed by either visual inspection with acetic acid (VIA) or mobile colposcopy with the enhanced visual assessment system. Results: Two hundred and seventy and 107 women were screened in the antenatal and postnatal groups, respectively. The mean ages were 29.4 (SD, 5.4) in the ANC group and 28.6 (SD, 6.4) years in the PNC group. The overall hr-HPV prevalence rate was 25.5% (95% confidence interval (CI), 21.1-29.9) disaggregated as 26.7% (95% CI, 21.4-31.9) in the ANC group and 22.4% (95% CI, 14.5-30.3) in the PNC group (p = 0.3946). Overall, 58.9% of pregnant women (28.3% hr-HPV+) and 66.4% of postnatal women (22.5% hr-HPV+) only visited a health facility when pregnant or after delivery (at Child Welfare Clinics). The VIA 'positivity' rate for all screened women was 5.3% (95% CI, 3.1-7.6), disaggregated into 5.2% (95% CI, 2.5-7.8) in the ANC group and 5.7% (95% CI, 1.3-10.1) in the PNC group (p-value = 0.853). Conclusion: A significant number of women in Ghana only visit a health facility during pregnancy or after delivery. ANC and PNC clinics would offer opportunities to increase coverage in cervical precancer screening in low-resource settings. Relying on community nurses ensures that such programs are readily integrated into routine care of women and no opportunity is missed.
ABSTRACT
Most cervical cancers develop in the transformation zone (TZ). Type 3 TZs, where the full circumference of the squamocolumnar junction (SCJ) is not visible pose problems during cervical screening with visual inspection methods, as (pre)cancerous lesions may be missed. Several practical strategies can be implemented to convert type 3 TZs into TZ 1 or TZ 2, including the use of an endocervical speculum or hygroscopic cervical dilators, opening the vaginal speculum more widely, skillful use of cotton-tipped applicators, performing colposcopy in midcycle, and use of oral or vaginal misoprostol and estrogen to 'ripen' the cervix. With the 2011 International Federation for Cervical Pathology and Colposcopy (IFCPC) terminology, settings with better resources to manipulate the cervix for a better view of the endocervical canal may assign patients to different categories from those in low-resource settings during a colposcopic examination. Here, we propose a colposcopic revision to the current IFCPC classification by segregating TZ 2 according to the extent of endocervical involvement and TZ 3 according to whether any attempt is made to open the endocervical canal, if such attempt(s) were successful, and the extent to which the practitioner can visualise parts of the uterine cervix beyond the border of the SCJ in the endocervical canal. In this proposed reclassification, TZ 2A has no part of the SCJ extending beyond 5 mm into the endocervical canal, whereas TZ 2B has part or all of the SCJ extending beyond 5 mm into the endocervical canal. TZ 3 is further subclassified into TZ 3A if the practitioner does not attempt to open the endocervical canal or the endocervical canal is opened, but not beyond 5 mm and TZ 3B if the full circumference cannot be visualised after opening the endocervical canal beyond 5 mm. We believe this revision will improve and better standardise the classification of TZ types, with huge implications for practice in low-resource settings, due to limited options for referral and treatment, to reduce the risk of missed cervical cancers and suboptimal treatment resulting from ablating lesions that extend too far into the endocervical canal.
ABSTRACT
Background: Human papillomavirus (HPV) DNA testing is more sensitive than cytology for detecting cervical precancer; however, increasing reports of high-risk HPV (hr-HPV)-negative cases of cervical intraepithelial neoplasia (CIN) and even malignancy motivate the use of combined testing. We present our experience with 'tritesting', defined as the performance of HPV DNA testing, cytology and visual inspection in a single session at the Cervical Cancer Prevention and Training Centre, Ghana. We further determined the prevalence rates of hr-HPV infection, abnormal cytology and cervical lesions among women screened using tritesting. Methods: This descriptive retrospective cross-sectional study assessed all women screened via tritesting between April 2019 to April 2023. HPV DNA testing was performed using the Sansure MA-6000, GeneXpert or AmpFire platforms. Visual inspection was performed using enhanced visual assessment mobile colposcopy or visual inspection with acetic acid. Liquid-based cytology was performed using cervical samples taken with a Cervex-Brush® and fixed in PreservCyt, while samples for conventional cytology were taken using an Ayre spatula and cytobrush. Results: Among 236 women screened (mean age, 39.1 years (standard deviation, 10.9)), the overall prevalence rates of hr-HPV infection and cervical lesions were 17.8% (95% confidence interval (CI), 13.1-23.3) and 11.9% (95% CI, 8.0-16.7), respectively. Cytology yielded findings of atypical squamous cells of undetermined significance or worse in 2.5% (95% CI, 0.9-5.5) of women. Histopathology following loop electrosurgical excision procedure revealed CIN I (tritest positive) and CIN III (hr-HPV-positive, visual inspection 'positive', cytology-negative) in one woman each. Factors independently associated with hr-HPV infection among 'tritested' women were age ≥ 39 years, tertiary level of education and current contraceptive use. Twenty-seven out of 39 hr-HPV-positive women (69.2%; 95% CI, 52.4-83.0) showed a type 3 transformation zone and would have needed to be recalled for a cytologic sample to be taken in a 'see and triage' approach with HPV DNA testing and a visual inspection method. Conclusion: This study brings tritesting into the spotlight, as an alternative to other methods, particularly for women who prefer this due to the advantage of a single visit to a health facility and being more cost-effective, if they have to travel long distances to access cervical screening services.
ABSTRACT
RESUMO Objetivo: Identificar a variabilidade espacial da mortalidade por câncer de mama e colo do útero e avaliar fatores associados à mortalidade por esses cânceres no município de São Paulo. Métodos: Entre 2009 e 2016 foram registrados, no Sistema de Informações sobre Mortalidade, 10.124 óbitos por câncer de mama e 2.116 óbitos por câncer do colo do útero em mulheres com 20 anos e mais. Os registros foram geocodificados por endereço de residência e agregados segundo território adstrito. Foram realizadas modelagens de regressão espacial utilizando-se a abordagem bayesiana com estrutura de Besag-York-Mollié para verificar a associação dos óbitos com indicadores selecionados. Resultados: As taxas de mortalidade por esses cânceres apresentaram padrões espaciais inversos. As variáveis associadas à mortalidade por câncer de mama foram: tempo de deslocamento para o trabalho entre uma e duas horas (risco relativo — RR 0,97; intervalo de credibilidade — IC95% 0,93-1,00); mulheres responsáveis pelo domicílio (RR 0,97; IC95% 0,94-0,99) e óbitos por câncer de mama ocorridos em estabelecimentos privados (RR 1,04; IC95% 1,00-1,07). À mortalidade por câncer do colo do útero, estiveram associados: tempo de deslocamento para o trabalho entre meia e uma hora (RR 0,92; IC95% 0,87-0,98); rendimento domiciliar até três salários-mínimos (RR 1,27; IC95% 1,18-1,37); e razão de menores de um ano em relação à população feminina de 15 a 49 anos (RR 1,09; IC95% 1,01-1,18). Conclusão: Foram calculados os RR preditos para a mortalidade por esses cânceres, que estiveram associados às condições socioeconômicas das áreas de abrangência.
ABSTRACT Objective: To identify spatial variability of mortality from breast and cervical cancer and to assess factors associated in the city of São Paulo. Methods: Between 2009 and 2016, 10,124 deaths from breast cancer and 2,116 deaths from cervical cancer were recorded in the Mortality Information System among women aged 20 years and over. The records were geocoded by address of residence and grouped according to Primary Health Care coverage areas. A spatial regression modeling was put together using the Bayesian approach with a Besag-York-Mollié structure to verify the association of deaths with selected indicators. Results: Mortality rates from these types of cancer showed inverse spatial patterns. These variables were associated with breast cancer mortality: travel time between one and two hours to work (RR - relative risk: 0.97; 95%CI - credible interval: 0.93-1.00); women being the head of the household (RR 0.97; 95%CI 0.94-0.99) and deaths from breast cancer in private health institutions (RR 1.04; 95%CI 1.00-1.07). The following variables were associated with mortality from cervical cancer: travel time to work between half an hour and one hour (RR 0.92; 95%CI 0.87-0.98); per capita household income of up to 3 minimum wages (RR 1.27; 95%CI 1.18-1.37) and ratio of children under one year of age related to the female population aged 15 to 49 years (RR 1.09; 95%CI 1.01-1.18). Conclusion: The predicted RR for mortality from these cancers were calculated and associated with the socioeconomic conditions of the areas covered.
ABSTRACT
BACKGROUND: Cervical cancer, the most common gynecological cancer, is a matter of concern, especially in developing countries. The present study investigates survival rates, associated factors, and post-treatment follow-up status in cervical cancer patients. STUDY DESIGN: A retrospective cohort study. METHODS: This study was conducted on 187 patients referred to an academic referral cancer center in Iran from 2014-2020. Overall survival (OS) and event-free survival (EFS) were evaluated using Kaplan Meyer analysis. The event was defined as recurrence, metastasis, or death. RESULTS: The patients came for post-treatment visits for a median of 36 months (interquartile range [IQR]: 18-51). The median OS and EFS were 24 and 18 months, respectively. The 1- and 3- year OS rates were 90% and 72%, respectively. The 1- and 3- year EFS rates were 76% and 61%, respectively. Stage ≥ III (hazard ratio [HR]: 3.1, 95% confidence interval [CI]: 1.5, 6.5, P < 0.001) and tumor size > 4 cm (HR: 2.5, 95% CI: 1.2, 4.9, P = 0.006) predicted lower OS. The most common histopathology was squamous cell carcinoma (SCC) (71.1%) with non-significant higher 3- year OS (HR: 0.62, 95% CI: 0.33, 1.16, P = 0.13). No significant difference in OS was found between adjuvant and definitive radiotherapy in both early and advance-staged patients (Log-rank = 0.7 P = 0.4, log-rank = 1.6, P = 0.2, respectively). CONCLUSION: As evidenced by the obtained results, the survival of patients was lower compared to that in developed countries. Higher stage and tumor size led to shorter survival. The histopathology and type of treatment in comparable stages did not have any significant impact on survival.

OBJECTIVE: To report a case and review literature of bowel metastases from cervical squamous cell carcinoma. CASE REPORT: A 49-year-old woman with a history of FIGO 2013 stage IVB cervical squamous cell carcinoma presented with refractory nausea, projectile vomiting, anorexia, postprandial abdominal pain, and significant weight loss for six months. Restaging images didn't reveal viable tumors but thickened duodenal wall indicating gastric outlet obstruction. Initially, the etiology was masked by chronic erosive duodenitis and mistreated as a duodenal ulcer. After repeated gastrointestinal endoscopic biopsy confirming intramural duodenal metastasis from cervical squamous cell carcinoma, the patient was treated successfully by gastrojejunostomy and adjuvant chemotherapy. She has remained asymptomatic and disease-free for more than 12 months since the surgical metastasectomy. CONCLUSION: Intestine metastasis from cervical cancer is a rare cause that may present as projectile vomiting due to gastric outlet obstruction. Prompt recognition and surgical intervention may provide good outcomes despite the metastatic nature.

Cervical cancer screening (CCS) by Pap tests is mainly performed by gynecologists in France, but also by general practitioners (GPs) and midwives. The screening uptake is insufficient to reduce the incidence of cervical neoplasms. Our aim was to investigate the association between screening rates in patients listed with GPs and the distance between GPs' offices and gynecology facilities. The population of 345 GPs, and their 93,918 female patients eligible for screening over 3 years (2013-2015), were derived from the Health Insurance claim database. We estimated the socioeconomic level of the geographical area of GPs' offices using the European Deprivation Index (EDI). The proximity of gynecology facilities was calculated by computing their distance from GPs' offices (in order to adjust the proximity of gynecology facilities with EDI and performance of smears by the GP). The number of gynecologists within 5 km of a GP's office was associated with the CCS rate increasing by 0.31% for every unit increase in the density of gynecologists within 5 km (p < 0.0001). The close proximity of gynecology facilities was not significantly associated with screening uptake among female patients when the office of the GP where they were registered was settled in a deprived area.
