Socioeconomic and cultural factors associated with pap smear screening among French women living in Réunion Island.

BACKGROUND: Réunion Island is a French overseas territory located in the southern Indian Ocean, with a challenging socioeconomic and multicultural context. Compared to mainland France, Réunion has an overincidence and overmortality of cervical cancer. In order to investigate these two issues, it is important to evaluate the barriers and potential levers to Pap smear screening among female inhabitants of the island. We aimed to identify the specific socio-demographic factors, cultural factors, and living conditions associated with Pap smear screening in Réunion, with a view to increasing uptake. METHODS: We conducted a Knowledge Attitude Behavior and Practices (KABP) survey on cervical cancer screening practices among women aged between 25 and 65 years old living in Réunion Island, selected using random digit dialing sampling. Data were collected using Computer Assistant Telephone Interviews. Weighted chi-squared tests and Student's t-tests were used to compare women who had up-to-date Pap smear screening with women who did not. Weighted logistic models were used to identify the factors associated with not having up-to-date screening. RESULTS: A total of 1000 women were included in the study. Of these, 88.1% had a Pap smear test during the previous three years. Factors independently associated with not being up to date were as follows: aged over 55 (AOR 2.3 [1.2-4.3]), no children (AOR 2.5 [1.4-4.3]), having free universal health coverage (AOR 1.7 [1.1-2.7]), an income per unit consumption lower than 1500€ per month (AOR 2.0 [1.1-3.7]), low health literacy (AOR 2.7 [1.7-4.1]), not consulting a general practitioner in the prior 12 months (AOR 3.6 [2.0-6.5]), and a BMI > 30 (AOR 2.6 [1.5-4.4]). CONCLUSIONS: This is the first large-scale survey focusing on recommended Pap smear screening uptake in Réunion Island. Although self-reported screening incidence was higher than in mainland France, national screening policies must take into account the island's diverse social and cultural characteristics (e.g., an ageing population, low health literacy), while implementing actions to fight against poverty and increase general access to healthcare.

Cervical precancerous and cancerous lesions screening using Pap smear test at Provincial Referral Hospital of Bukavu, Eastern DR Congo: profile and recommendations to stakeholders.

Introduction: cervical cancer is a health concern worldwide. The South Kivu Province in the Eastern DR Congo is facing many cases of this disease but poorly screened and reported. The objective of this was to determine the prevalence of cell abnormalities at cervical cytology in a tertiary teaching hospital in Bukavu and their association with common risk factors of cervical cancer. Methods: a cross-sectional study was conducted on 142 women attending the Provincial Referral Hospital of Bukavu (HPGRB) from February to December 2021. Quantitative variables were described by their median following their asymmetric distributions and the qualitative variables in absolute and relative frequencies. Then the Chi-square test was used for the comparison of proportion. Results: forty-five percent of the participants had between three and five children. Twenty-two (15.5%) of the 142 patients reported to have two or more sexual partners and 17.5% reported the use of hormonal contraception. The prevalence of cell abnormalities at cervical cytology was 17% of which Low- Grade Squamous Intraepithelial Lesion (LSIL) was the most representative (12.9%). There was no statistically significant association between the common cervical risk factors and the occurrence of cell abnormalities. Conclusion: cervical pre-cancerous lesions are frequent in South Kivu province. The Pap smear test remains an early and affordable screening method and constitutes a secondary prevention strategy in women of 18 years and older in a low-income country such as DR Congo where vaccination against HPV is still hypothetic.

Clinical characteristics, HPV involvement, and demographic risk factors in women with cervical intraepithelial neoplasia complicated by vaginal intraepithelial neoplasia.

PURPOSE: This study aimed to explore the clinical characteristics and risk factors associated with cervical intraepithelial neoplasia (CIN) when coexisting with vaginal intraepithelial neoplasia (VAIN). METHODS: We analyzed the clinical data of 212 patients diagnosed with CIN, including 50 patients with concurrent VAIN. The groups were compared to identify distinct clinical features and independent risk factors for the co-occurrence of CIN and VAIN, using logistic regression analysis. RESULTS: Patients with both CIN and VAIN had a median age of 57, significantly older than the 41-year median age of patients with CIN only (P < 0.05). A higher prevalence of HPV infection (98.0%) was observed in the CIN and VAIN group, with a notable rate of multiple HPV infections (67.3%) compared to the CIN-only group (P < 0.05). Educational levels were significantly lower in the combined CIN and VAIN group (P < 0.05). HPV16, 33, and 52 were identified as significant types for single and multiple infections. Multivariate analysis confirmed age as an independent risk factor for CIN with VAIN (P < 0.05). VAIN3 patients were more likely to exhibit HSIL and ASC-H, whereas VAIN1 cases tended to correspond with ASCUS and LSIL diagnoses. CONCLUSION: The co-occurrence of CIN and VAIN is significantly influenced by patient age and educational level. The findings advocate for more diligent vaginal examination during colposcopy in older patients, particularly those with multiple HPV infections and cytological abnormalities, to enhance the early detection of vaginal lesions and prevent missed diagnoses and treatments. Additionally, the high prevalence of HPV infection, especially with certain types, underscores the importance of HPV monitoring in this patient population.

Pap Smear Cancer Coverage in Brazilian Capitals including the Pandemic Period Caused by the SARS-CoV-2 Virus: Ecological Study.

INTRODUCTION: Cervical cancer develops slowly and may not manifest signs and symptoms at an early stage. It is worth mentioning the factors that can influence the onset of cervical cancer: smoking, early sexual life, multiple sexual partners, use of oral contraceptives, multiparity, low socioeconomic status, among others. An important risk factor for the onset of this disease is HPV infection, a virus associated with most cases of precursor lesions of this type of cancer. It is essential to understand the comprehensiveness of the scope and adherence to the recommended guidelines throughout the national territory. Therefore, health indicators are important management tools that make it possible to evaluate the services offered, measuring the reach of the target population, the supply and access to preventive exams. OBJECTIVE: To analyze the trend of progress in cervical cancer coverage actions in Brazilian capitals from 2016 to 2021. METHOD: This is an ecological study with temporal analysis that used secondary data referring to process indicators for cervical cancer control actions in women aged between 25 and 64 years living in Brazilian capitals between 2016 and 2021. Aspects related to the quality of care in the cervical cancer prevention program were evaluated using databases of the Cancer Information System (SISCAN), available in DATASUS. The indicators used to monitor and evaluate cervical cancer control actions were (i) cervical coverage, (ii) reason for cervical surgery, and (iii) proportion of cervical cancer every 3 years. RESULTS: In 2016, 410,000 tests were performed and notified in the SISCAN system in all Brazilian capitals, with emphasis on Curitiba, with 65,715 tests performed, and Porto Velho, with 174. In 2020, there was a reduction in exams compared to the previous year in all capitals, with the exception of Palmas, which went from 7655 exams to 9604. It was observed that all the capitals studied showed an increase in the annual percentage variation of Pap smear coverage, with the exception of Brasília, Manaus, Porto Alegre and Porto Velho, which did not show a statistically significant increase (APC = 3.01, 2.746, 3.987, 3.69, respectively). When analyzing the performance of oncotic cytology exams in the capitals according to the years 2019 and 2020, it was observed that only Manaus registered an increase in the number of procedures performed, reaching a difference of 56.5% from one year to the next. CONCLUSION: The ecological analysis revealed a worrying drop in the number of tests performed in 2020, reflecting a sharp drop in coverage actions in Brazilian capitals during the pandemic caused by the SARS-CoV-2 virus. The pandemic has exacerbated existing inequalities and highlighted the need for adaptive strategies to maintain essential screening services in times of crisis.

[The timeline of the screening and treatment strategy of intraepithelial neoplasia of the uterine cervix adopted in Morocco]. / La chronologie d'évolution des modes de dépistage et de traitement des néoplasies intra épithéliales du col utérin adoptés au Maroc.

In Morocco, the purpose of the National Cancer Prevention and Control Plan (PNPCC) is to decrease the incidence, mortality, and morbidity attributable to cervical cancer (CC), including the general objective which is to improve women´s care by setting up an organized system for screening, early diagnosis and treatment of this disease, and as operational objectives an: 1) achievement of at least 30% of the annual coverage rate by cervical cancer (CC) screening; 2) achievement of at least 80% of the rate of participation in CC screening per screening cycle; 3) achievement of 100% of the treatment rate for precancerous lesions screened within the framework of the program. CC screening concerns all women aged 30 to 49 years old. Women who have already had CC and pregnant women from the 8th week of amenorrhea until the 6th week postpartum are excluded from the program. The screening test currently used is the naked eye inspection with acetic acid or visual inspection with acetic acid (VIA), which will be followed by a colposcopy exam and biopsy if a precancerous lesion is confirmed. The VIA is carried out at the level of urban and rural health centers, by a trained health professional. Knowing that the pap-smear test was widely used before. Thermo coagulation, also called: cold coagulation, is currently the main treatment for intraepithelial lesions (LIE) that are eligible for this treatment, and finally the national program has introduced anti-HPV vaccination within the national vaccination program (NPI).

Correlation between high-risk HPV infection and p16/Ki-67 abnormalities in Pap samples in a South Eastern Europe cohort.

Cervical cancer (CC) is the fourth most common cause of cancer-related deaths amongst women worldwide. CC represents a major global healthcare issue, and Romania ranks the worst in mortality rates amongst EU countries. However, the early detection of CC can be lifesaving. To understand the testing process undergone by women in Romania, we performed a retrospective study, and investigated a cohort of 83 785 cervical cases from Romanian women aged 15-70, obtained in private-based opportunistic screening. We examined the correlation between Pap smear results, human papilloma virus (HPV) genotyping, and the expression of cell cycle markers p16 and Ki-67. Analysis of Pap results revealed approximately 10% abnormal cases, of which high-grade squamous intraepithelial lesions constituted 4.9%. HPV genotyping of 12 185 cases with available Pap results unveiled a range of high-risk HPV (hrHPV) types associated with cervical abnormalities. Notably, 26% of hrHPV-positive cases showed no observable abnormalities. In a subset of cases with abnormal Pap and a type of hrHPV, P16/Ki-67 double-staining was also positive. This study suggests the importance of an integrated diagnostic algorithm that should consider the HPV genotype, Pap smear, and p16/Ki-67 staining. This algorithm should enhance the CC screening accuracy and its management strategies, particularly in those regions with a high disease burden, such as Romania.

An audit of 1632 routinely collected cervical cancer screening smears from 398 women in Germany: Results from the TeQaZ Study.

OBJECTIVE: There is evidence in Germany that half of the cervical cancer (CC) cases had undergone screening frequently in the decade preceding their diagnosis, signaling cytology quality issues. This study investigates routine smear assessment accuracy in Germany. METHODS: Within a population-based case-control study in 9 German states, we recruited cases (women with a histologically confirmed diagnosis of CC) and population controls (women with no history of CC or hysterectomy). Two independent expert cytologists audited Pap smears taken within the 10 years preceding CC diagnosis (cases)/study entry (controls). We report the prevalence of positive results, as well as routine assessment's accuracy, as sensitivity, specificity, false-positive and false-negative rates along with 95% confidence intervals (95% CI). We also examined cases' smear history, to investigate possible false-positive recurrence. RESULTS: We audited 1632 smears of 392 women (18.9% cases, 81.1% controls). In the routine assessment, the overall prevalence of positive results was 4.5% (29.0% among cases). According to the expert audit, the overall prevalence of positive results was 7.7% (40.8% among cases). When restricting analyses to the 3 years preceding diagnosis/study entry, this prevalence increased to 11.9% overall (61.4% among cases). The overall sensitivity of the routine assessment was 54.9% (66.8% for cases). CONCLUSION: As cytology remains an important part of CC screening, quality issues must be urgently addressed in Germany. Shifting to objective methods such as primary high-risk HPV screening followed by triaging may help CC elimination in Germany.

Analysis of the Differences between Bethesda Groups according to Conventional Smear and Liquid-Based Cytology Methods in Cervicovaginal Cytology: A Single-Center Experience with 165,915 Cases.

INTRODUCTION: Liquid-based cytology (LBC) has replaced conventional smear (CS) in the world. In this study, through a series with a large number of cases, we aimed to make a comparison and general evaluation in all groups, primarily epithelial abnormalities, according to LBC and CS methods. This study was carried out in a private pathology laboratory located in a metropolitan city, where cytological materials sent from many clinics were examined. MATERIAL AND METHODS: There were 165,915 cases whose smears were examined between 2012 and 2020, most of them conventional (131,224 CS, 34,691 LBC). Cases were evaluated on the basis of the Bethesda 2014 classification and divided into sub-diagnostic categories after they were divided into two main groups as "with epithelial abnormalities" and "without." χ2 and Fischer's precision statistical tests were conducted using SPSS 23.0 package. In the CS process, cervical samples were obtained using an endocervical brush and a spatula. Cells were directly spread onto the slides and promptly fixed in 95% ethanol, followed by staining with the standard Papanicolaou stain. For LBC ThinPrep, cervical specimens were gathered using a cervix brush. The brush was washed in a vial and discarded. Finally, cells were isolated through vacuum filtration and transferred to the slide using air pressure. RESULTS: Squamous cell abnormalities (atypical squamous cells of undetermined significance [ASC-US], atypical squamous cells - cannot exclude high-grade squamous intraepithelial lesion [ASC-H], low-grade squamous intraepithelial lesion [LSIL], high-grade squamous intraepithelial lesion [HSIL], squamous cell carcinoma, atypical glandular cells of undetermined significance) were reported in 5,696 (3.43%) cases. ASC (ASC-US + ASC-H)/SIL ratio (1.36/2.04) was found to be 0.67 (recommended Bethesda ratio is <3). ASC-US (p < 0.001), ASC-H (p < 0.001), and HSIL(p < 0.001) detection rate of LBC was found to be significantly higher than CS. ASC-US (1.8/1.2), ASC-H (0.08/0.008), and HSIL (0.6/0.3) case ratios of LBC/CS were found to be significantly higher in LBC. LSIL (1.72/1.66) rate was similar. CONCLUSION: LBC is superior to CS in detecting epithelial lesions. In addition to being used as a screening method, it is clear that it makes a great contribution to reducing cervical carcinomas due to HPV typing. Definitive comments regarding comparison of methods on reactive changes and microorganism detection are challenging. Preanalytical factors might account for these situations.

Hsa-miR-194-5p and hsa-miR-195-5p are down-regulated expressed in high dysplasia HPV-positive Pap smear samples compared to normal cytology HPV-positive Pap smear samples.

BACKGROUND: The human papillomavirus (HPV) infection may affect the miRNA expression pattern during cervical cancer (CC) development. To demonstrate the association between high-risk HPVs and the development of cervix dysplasia, we examined the expression patterns of hsa-miR-194-5p and hsa-miR-195-5p in Pap smear samples from southeast Iranian women. We compared samples that were HPV-positive but showed no abnormality in the cytological examination to samples that were HPV-positive and had severe dysplasia. METHODS: Pap smear samples were obtained from 60 HPV-positive (HPV-16/18) patients with histologically confirmed severe dysplasia (cervical intra-epithelial neoplasia (CIN 3) or carcinoma in situ) and the normal cytology group. The expression of hsa-miR-194-5p and hsa-miR-195-5p was analyzed by real-time quantitative PCR, using specific stem-loop primers and U6 snRNA as the internal reference gene. Clinicopathological features were associated with miRNA expression levels. Furthermore, functional enrichment analysis was conducted using in silico tools. The Kaplan-Meier survival method was also obtained to discriminate survival-significant candidate miRNAs in CC, and receiver operating characteristic (ROC) curves were constructed to assess the diagnostic value. RESULTS: Compared to HPV-positive cytologically normal Pap smear samples, hsa-miR-194-5p and hsa-miR-195-5p relative expression decreased significantly in HPV-positive patients with a severe dysplasia Pap smear. Kaplan-Meier analysis indicated a significant association between the miR-194 decrease and poor CC survival. In essence, ROC curve analysis showed that miR-194-5p and miR-195-5p could serve as valuable markers for the development of cervix dysplasia in individuals who are positive for high-risk HPVs. CONCLUSIONS: This study revealed that hsa-miR-194-5p and hsa-miR-195-5p may possess tumor suppressor capabilities in the context of cervical dysplasia progression. However, it remains uncertain whether these microRNAs are implicated in the transition of patients with high dysplasia to cervical cancer. We also showed the potential capability of candidate miRNAs as novel diagnostic biomarkers related to cervical dysplasia progression.

Occult invasive cervical cancer, FIGO stage III, with a negative Pap smear test - clinical presentation and brief review of the literature.

Occult cervical cancer is rare and is diagnosed incidentally after a simple hysterectomy. The staging upon histological examination is usually International Federation of Gynecology and Obstetrics (FIGO) stage I, rarely higher with negative preoperative diagnostic tests such as a Pap smear. The clinical case in question is a rare case of cervical carcinoma diagnosed at the time of hysterectomy with a negative exo-endocervical Pap smear, diagnostic tests including transvaginal ultrasound, abdominal magnetic resonance imaging and abdominal computed tomography with a diagnosis of degenerating myoma or suspected sarcoma. In the operating theatre, the surgical radicality was modified and the operation was completed with removal of the parameters, vaginal collar and bilateral pelvic lymphadenectomy. The final histological examination indicated FIGO stage III, for which the patient underwent radiotherapy and chemotherapy.

Overlapping cytoplasms segmentation via constrained multi-shape evolution for cervical cancer screening.

Segmenting overlapping cytoplasms in cervical smear images is a clinically essential task for quantitatively measuring cell-level features to screen cervical cancer This task, however, remains rather challenging, mainly due to the deficiency of intensity (or color) information in the overlapping region Although shape prior-based models that compensate intensity deficiency by introducing prior shape information about cytoplasm are firmly established, they often yield visually implausible results, as they model shape priors only by limited shape hypotheses about cytoplasm, exploit cytoplasm-level shape priors alone, and impose no shape constraint on the resulting shape of the cytoplasm In this paper, we present an effective shape prior-based approach, called constrained multi-shape evolution, that segments all overlapping cytoplasms in the clump simultaneously by jointly evolving each cytoplasm's shape guided by the modeled shape priors We model local shape priors (cytoplasm-level) by an infinitely large shape hypothesis set which contains all possible shapes of the cytoplasm In the shape evolution, we compensate intensity deficiency for the segmentation by introducing not only the modeled local shape priors but also global shape priors (clump-level) modeled by considering mutual shape constraints of cytoplasms in the clump We also constrain the resulting shape in each evolution to be in the built shape hypothesis set for further reducing implausible segmentation results We evaluated the proposed method in two typical cervical smear datasets, and the extensive experimental results confirm its effectiveness.

Socioeconomic disparities in Papanicolaou test utilization in Western Iran.

BACKGROUND: Cervical cancer remains the fourth most frequently diagnosed cancer among women, and its impact is particularly significant in women residing in less developed countries. This study aims to assess socioeconomic inequality in using Papanicolaou tests, commonly known as Pap tests, which are crucial for detecting cervical cancer. The research also seeks to decompose this inequality, identifying its contributing factors. This investigation is conducted within a sizable population-based study focused on the Kurdish population, with an additional examination of potential variations between urban and rural areas. METHOD: The study utilized baseline data from the Ravansar Non-Communicable Disease Cohort Study (RaNCD), involving 3,074 ever-married women aged 35-65. Asset data was employed to determine socioeconomic status (SES), and Principal Component Analysis was applied. The uptake of Papanicolaou tests was assessed for inequality using the Concentration Index (Cn). Additionally, decomposition analysis was conducted to identify and understand the factors contributing to socioeconomic inequality. RESULTS: The study found that overall, 86% of women reported having undergone cervical cancer screening at least once in their lifetime. The Concentration Index (Cn) for the total population was 0.21 (p < 0.0001), indicating a higher concentration of Papanicolaou test uptake among wealthier groups. In urban areas, the Cn was 0.34 (p < 0.0001), reflecting a significant concentration among the rich. However, in rural areas, the Cn was -0.10 (p = 0.3006), suggesting no significant socioeconomic inequality. Factors such as socioeconomic status (SES), education, and age contributed to reducing inequality, explaining 62.7%, 36.0%, and 1.7% of the observed inequality, respectively. Interestingly, place of residence had a negative influence on inequality. CONCLUSION: The uptake of Papanicolaou tests varies across different socioeconomic status levels, with a higher concentration among wealthier groups. The results enable health policymakers and researchers to tailor health intervention toward increasing public awareness, especially among women with lower levels of education women in economically deprived groups.

The Effect of Disability and Social Determinants of Health on Breast and Cervical Cancer Screenings During the COVID-19 Pandemic.

Introduction: The objective of this study was to examine the effect of disability status and social determinants of health (SDOH) on adherence to breast and cervical cancer screening recommendations during the COVID-19 pandemic. Methods: We conducted a secondary analysis of the 2018 and 2020 Behavioral Risk Factor Surveillance System (BRFSS) data sets. We defined adherence to screenings according to the US Preventive Services Task Force guidelines for breast and cervical cancer screening. The analysis included respondents assigned female at birth, aged 50 to 74 years (breast cancer screening) or aged 21 to 65 years (cervical cancer screening). We performed logistic regression to evaluate breast and cervical cancer screening adherence, by disability status and SDOH (health insurance coverage, marital status, and urban residency), independently and simultaneously. Results: Our analysis included 27,526 BRFSS respondents in 2018 and 2020. In 2018, women with disabilities had lower adjusted odds than women without disabilities of being up to date with mammograms (adjusted odds ratio [AOR] = 0.76, 95% CI, 0.63-0.93) and Pap (Papanicolaou) tests (AOR = 0.73; 95% CI, 0.59-0.89). In 2020, among women with disabilities, the adjusted odds of mammogram and Pap test adherence decreased (AOR = 0.69; 95% CI, 0.54-0.89; AOR = 0.59; 95% CI, 0.47-0.75, respectively). In 2018, the adjusted odds of mammogram adherence among rural residents with and without disabilities were 0.83 (95% CI, 0.70-0.98), which decreased to 0.76 (95% CI, 0.62-0.93) in 2020. Conclusion: The findings of this study highlight the effect of disability status and SDOH on breast and cervical cancer screening rates during the COVID-19 pandemic. Public health strategies that acknowledge and address these disparities are crucial in preparing for future public health crises.

Community cervical cancer screening and precancer risk in women living with HIV in Jos Nigeria.

BACKGROUND: High HIV prevalence, and lack of organized screening for the indigent population receiving care and treatment within HIV clinics in low-resource settings increases cervical cancer incidence. We sought to determine predictors of cervical precancer in women living with HIV and receiving cervical cancer screening in Jos, Nigeria. METHODS: A cross-sectional study of women living with HIV and receiving care and treatment in adult HIV/AIDS clinics in Jos-Metropolis, Nigeria between June 2020 and April 2023. Ethical approvals were obtained from the ethics committee in Jos, Nigeria and Northwestern University IRB, USA. Informed consent was obtained from eligible participants, and data on socio-demographics, cancer risk factors, and cytology reports were collected. The outcome variables were cervical precancer lesions. The independent variables were prior Pap smear status, socio-demographics, income, educational, and other reproductive health factors. Descriptive statistics was done to obtain means ± sd, frequencies, and percentages for the variables. Univariate and bivariate analyses were done to determine predictors of cervical dysplasia. Analyses were performed using R software. RESULTS: Of 957 women screened, 570 were living with HIV and 566 women had cytology report and were included in the final analysis. The mean age was 45.08 ± 8.89 years and 81.6% had no prior evidence of Pap test (under-screened). Prevalence of cervical dysplasia was 24% (mild and severe dysplasia were 12.9% and 11.1%, respectively). Age above 45 years (aOR = 3.48, p = 0.009), postmenopausal status (aOR = 7.69, p = 0.000), and women with no history of prior IUCD use (aOR = 5.94, p = 0.0001), were predictors for severe dysplasia. Women who had history of STI (aOR = 0.17, p = 0.000), prior use of IUCD (aOR = 0.32, p = 0.004), prior use of condom (aOR = 2.50, p = 0.003) and had co-morbidities (aOR = 0.46, p = 0.009) were more likely to have had a Pap test in the past. CONCLUSIONS: The majority of indigent women receiving care at HIV clinics had their first Pap test screening, and lack of organized screening among older and post-menopausal women with HIV, puts women at a higher risk of developing severe cervical precancer lesions.

What rate of Iranian women perform Pap smear test? Results from a meta-analysis.

In this study, an attempt was made to estimate the aggregated proportion of Pap smear test uptake among women in Iran from 2012 to 2022 using meta-analysis. The data collection process involved reviewing records registered in databases between January 1, 2012, and September 11, 2022. The final data was analyzed using random effects models, and potential heterogeneity was assessed using the I2 index. To examine publication bias, Egger's test and Funnel Plot were employed. Sensitivity analysis, specifically single study exclusion Meta-analysis, was conducted to assess the influence of each individual study on the aggregated percentage of Pap smear test uptake. A total of 28,754 women were included across the 33 articles analyzed. The pooled percentage of Pap smear test uptake for both one-time and regular screenings was found to be 46.52% (95% CI: 40.91 to 52.14) and 17.80% (95% CI: 12.42 to 23.18), respectively. No significant evidence of publication bias was detected, although the influence of smaller studies was confirmed. Sensitivity analysis indicated that the overall rate of Pap smear test uptake was not highly sensitive to the results of individual studies. The findings emphasize the low rate of regular Pap smear testing among Iranian women and suggest that tailored interventions considering cultural and geographical factors specific to different provinces in Iran could help increase the utilization of this screening service.

Retrospective Investigation of Human Papillomavirus Cervical Infection and Lymphoma Incidence: A Clinical and Pathological Evaluation.

OBJECTIVE: Human papillomavirus (HPV) persistence is considered the main risk factor for neoplastic progression, and evidence suggests that regulatory T cells play an important role in the failure of viral elimination. Regulatory T cells may be involved in maintaining a microenvironment favourable for viral persistence and neoplasticity, through a deregulation of the local immune response. The association between altered immune function and the development of chronic infections, cancer (solid and haematological), and autoimmune diseases is documented in the literature. The purpose of this retrospective analysis was to evaluate the possible correlation between HPV cervical infection and lymphoma incidence in women attending colposcopy due to an abnormal Pap smear during a period of 15 years. DESIGN: This is a cross-sectional study. PARTICIPANTS: We investigated retrospectively the incidence of haematological diseases in women aged 21-84 with an abnormal Pap smear who referred to our centre between 2004 and 2019. SETTING: This study was conducted at the university hospital. METHODS: In our analysis, we included women with diagnoses of HL and NHL after the detection of abnormal Pap smears and HPV infections. We excluded patients with a diagnosis of lymphoma preceding the date of the abnormal Pap smear and HPV test. RESULTS: We divided the patients into two groups in order to analyse the standard incidence ratio (SIR): HL patients (19/7,064, 0.26%) and NHL patients (22/7,064, 0.31%). In our sample, we reported a significant risk of developing lymphoma compared to the general population, both for HL and NHL disease, at age <45 years. Regarding HL, the SIR of disease in women <45 years was 4.886 (95% CI 2.775-9.6029) and in women between 45 and 59 years was 2.612 (95% CI 0.96-7.108804). On the other hand, for NHL in women <45 years, we reported an SIR of about 3.007 (95%, CI 1.273-7.101575), in women aged 45-59 years, the SIR was 4.291 (95% CI 2.444-7.534399), and in women aged 60-74 years, the SIR was 3.283 (95% CI 1.054-10.22303). LIMITATIONS: This retrospective analysis was conducted in a single centre in Northern Italy and did not consider all interregional differences existing in the country in terms of HPV genotypes, ethnicity, and population characteristics. Regarding the analysis of SIR for HL and NHL, we did not divide the disease into subtypes because of the small sample of cases. Finally, we considered in our analysis only women with an abnormal Pap smear and not the general population. CONCLUSIONS: Women with chronic and persistent HPV infections may have a higher relative risk of developing lymphoma. This possible association may be caused by the deregulation of the immune system response against HPV and the failure of viral clearance, especially in younger women.

Knowledge of cervical cancer screening among Omani women attending a university teaching hospital: a cross-sectional study.

OBJECTIVES: To assess knowledge, attitudes, and practices regarding cervical cancer and Pap smear screening among Omani women attending a tertiary clinic in Muscat, Oman, and to establish correlations with selected sociodemographic factors. METHODS: An observational, cross-sectional study was carried out among Omani women aged 18-50 years old attending the outpatient clinic of the Department of Obstetrics and Gynecology, Sultan Qaboos University Hospital, from October 2019 to February 2020. A validated Arabic-language questionnaire was utilized to collect data regarding the participants' sociodemographic characteristics, their knowledge of cervical cancer and related risk factors, and their knowledge, attitudes, and practices related to cervical cancer screening and Pap smear testing. RESULTS: Of the 380 respondents, 86 and 55% had previously heard of cervical cancer and Pap smear testing, respectively; however, only 26% were knowledgeable concerning these topics. Knowledge scores were significantly associated with various sociodemographic factors, including marital status and a previous awareness of cervical cancer (odds ratio: > 1, p < 0.05). Only 21% had themselves previously undergone Pap smear testing; however, 75% reported being willing to undergo such screening in future. CONCLUSIONS: Knowledge regarding cervical cancer-related risk factors and Pap smear screening was poor among a cohort of Omani women attending a tertiary clinic in Muscat, Oman. This may play a role in the increased frequency of cervical cancer cases observed in Oman over recent years. As such, a well-structured public education program is recommended to raise awareness of this issue.

Our experience diagnosing 225 patients with cervical glandular lesions: current technologies, lessons learned, and areas for improvement.

OBJECTIVE: To explore the relative sensitivity of different methods for detecting cervical glandular lesions. METHODS: A total of 225 patients with cervical glandular lesions diagnosed from January 2018 to February 2023 were retrieved from the pathology database of Guangdong Maternal and Child Health Hospital, and their clinicopathological features were reviewed. RESULTS: Four human papillomavirus (HPV) genotypes: HPV18, 16, 45, and 52, dominated all glandular lesions, and accounting for 74.10% of HPV-positive tumors. Furthermore, 36.89% of abnormal squamous cells were diagnosed as abnormal based on cytological examinations leading to the detection of cervical glandular lesions; only 16.89% were diagnosed based on the initial detection of abnormal glandular cytology. The most common abnormal cervical screening result was ASC-US on cytology (14.22%), followed by HSIL (11.56%). Only few number of patients were diagnosed with or suspected of having cervical adenopathy via a Pap test (18.22%). Nearly one-third of cervical glandular lesions cases were not detected on the Pap test; but were diagnosed upon cervical biopsy or based on the histological examination of ECC, LEEP, or CKC specimens. The LEEP or CKC biopsy specimens had negative margins in 49 cases (40.83%), while the margins were positive in the other 71 cases (59.17%). Five cases (10.20%) with negative margins still had residual lesions following total hysterectomy, and 19 (26.76%) with positive margins had no residual lesions after total hysterectomy. CONCLUSION: The ability to detect cervical glandular lesions varies for routine HPV genotyping, Pap test, or biopsy/ECC, with different sensitivities and advantages and disadvantages for each method.
