RESUMEN

The role of artificial intelligence (AI) in pathology offers many exciting new possibilities for improving patient care. This study contributes to this development by identifying the viability of the AICyte assistive system for cervical screening, and investigating the utility of the system in assisting with workflow and diagnostic capability. In this study, a novel scanner was developed using a Ruiqian WSI-2400, trademarked AICyte assistive system, to create an AI-generated gallery of the most diagnostically relevant images, objects of interest (OOI), and provide categorical assessment, according to Bethesda category, for cervical ThinPrep Pap slides. For validation purposes, 2 pathologists reviewed OOIs from 32,451 cases of ThinPrep Paps independently, and their interpretations were correlated with the original ThinPrep interpretations (OTPI). The analysis was focused on the comparison of reporting rates, correlation between cytological results and histologic follow-up findings, and the assessment of independent AICyte screening utility. Pathologists using the AICyte system had a mean reading time of 55.14 seconds for the first 3000 cases trending down to 12.90 seconds in the last 6000 cases. Overall average reading time was 22.23 seconds per case compared with a manual reading time approximation of 180 seconds. Usage of AICyte compared with OTPI had similar sensitivity (97.89% vs 97.89%) and a statistically significant increase in specificity (16.19% vs 6.77%) for the detection of cervical intraepithelial neoplsia 2 and above lesions. When AICyte was run alone at a 50% negative cutoff value, it was able to read slides with a sensitivity of 99.30% and a specificity of 9.87%. When AICyte was run independently at this cutoff value, no sole case of high-grade squamous intraepithelial lesions/squamous cell carcinoma squamous lesion was missed. AICyte can provide a potential tool to help pathologists in both diagnostic capability and efficiency, which remained reliable compared with the baseline standard. Also unique for AICyte is the development of a negative cutoff value for which AICyte can categorize cases as "not needed for review" to triage cases and lower pathologist workload. This is the largest case number study that pathologists reviewed OOI with an AI-assistive system. The study demonstrates that AI-assistive system can be broadly applied for cervical cancer screening.

RESUMEN

BACKGROUND: While various interventions have been conducted to decrease cervical cancer's burden in Nigeria, no study has examined the trends in cervical cancer screening uptake over time. The present study sought to fill this gap in knowledge using data collected at Jos University Teaching Hospital (JUTH) in Nigeria. METHODS: Data collected continuously between 2006 and 2016 were analyzed to identify trends in screening uptake, changes in risk factors for cervical cancer, and to identify factors for women screened at Jos University Teaching Hospital (JUTH) in Jos, Nigeria. Categorical analyses and logistic regression models were used to describe patient characteristics by year, and to identify factors associated with repeated screening uptake. RESULTS: A total of 14,088 women who were screened between 2006 and 2016 were included in the database; 2,800 women had more than one screening visit. Overall, screening uptake differed significantly by year. On average women were first screened at age 38. About 2% of women screened were women living with HIV. Most women (86%) had normal pap smear at first screening, with the greatest decreased risk of abnormalities observed between 2011 and 2014. Odds of a follow-up screening after a normal result decreased significantly between 2008 and 2016 compared to women screened in 2006 and 2007. Finally, women living with HIV had increased odds of follow-up screening after having a normal pap smear. CONCLUSIONS: These findings contribute to our understanding of the potential social and health system barriers to cervical cancer control in Nigeria. The findings may assist policy makers to design interventions to increase access and compliance to recommended screening schedules in this vulnerable population.

RESUMEN

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.

RESUMEN

BACKGROUND: Cervical cancer is the fourth most common cancer among women worldwide, both for incidence and mortality. Prevention relies on screening with a Pap test to detect precancerous lesions, which can then be treated. Access to this screening is currently both improvable and inequitable. Pregnancy may be an ideal moment for women to catch up on their overdue cervical cancer screening. In the general population, women's risk of not being screened is associated with their place of birth and other social factors; this may be true as well among pregnant women. Our objective was to study the association between women's place of birth and their failure to catch up with this screening during pregnancy. METHODS: The 2016 French National Perinatal Survey included 13,147 women who gave birth after 21 weeks of gestation. The association between their place of birth and failure to catch up on this screening (defined by the absence of a Pap test during pregnancy for women overdue for it) was adjusted for age, parity, education level, health insurance, and when they began prenatal care with logistic regression models. RESULTS: Among the women for whom screening was then recommended, 49% were not up to date at the start of pregnancy, and of these, 53% were not caught up before delivery. After adjustment for other risk factors, maternal place of birth was not associated with a higher risk of failure to catch up with this screening during pregnancy. However, factors identified as associated with this risk included a low education level and late start of prenatal care. CONCLUSION: About half of women overdue for cervical cancer screening did not catch up with it during their pregnancy. Professionals should pay special attention to women with lower education levels and late initiation of prenatal care, who constitute a group at high risk of not catching up on this screening during pregnancy.

RESUMEN

BACKGROUND: Cervical cancer (CxCa), although preventable, is still among the most prevalent cancers in women. Mortality from this cancer is high, especially in low-income countries where preventive strategies are often lacking. We studied the knowledge, attitudes, and practices regarding CxCa among Yemeni women. METHODS: This cross-sectional study was conducted in 2019 among 399 women in five major hospitals in Sanaa, the capital city of Yemen. Data were collected through face-to-face interviews using structured questionnaires. We used logistic regression models to analyze the likelihood of hearing about CxCa, believing that CxCa is treatable and preventable, awareness of the Pap smear test, and ever having this test, in relation to participant's age, education level, working outside the household, and family history of CxCa. RESULTS: Only 66.7% of the women had heard of CxCa. Women with higher education, working outside the household, and with a family history of CxCa were more likely to be aware of CxCa. Working outside the household was the only variable related to a higher likelihood of knowing that CxCa is a treatable and preventable. Furthermore, women with a family history of CxCa were more likely to have knowledge about Pap smear test and were more likely to have Pap smear test in the past. CONCLUSION: This study identified a low awareness of CxCa and its prevention among Yemeni women. In order to reduce the burden of CxCa in Yemen and save women's lives, it is necessary to raise women's awareness of this disease, especially among those with lower education and those not involved in work outside their homes.

RESUMEN

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.

RESUMEN

OBJECTIVE: The fight against cervical cancer requires effective screening together with optimal and on-time treatment along the care continuum. We examined the impact of cervical cancer testing and treatment guidelines on testing practices, and follow-up adherence to guidelines. METHODS: Data from Estonian electronic health records and healthcare provision claims for 50,702 women was used. The annual rates of PAP tests, HPV tests and colposcopies during two guideline periods (2nd version 2012-2014 vs 3rd version 2016-2019) were compared. To assess the adherence to guidelines, the subjects were classified as adherent, over- or undertested based on the timing of the appropriate follow-up test. RESULTS: The number of PAP tests decreased and HPV tests increased during the 3rd guideline period (p < 0.01). During the 3rd guideline period, among 21-29-year-old women, the adherence to guidelines ranged from 38.7% (44.4…50.1) for ASC-US to 73.4% (62.6…84.3) for HSIL and among 30-59-year-old from 49.0% (45.9…52.2) for ASC-US to 65.7% (58.8…72.7) for ASCH. The highest rate of undertested women was for ASC-US (21-29y: 25.7%; 30-59y: 21.9%). The rates of over-tested women remained below 12% for all cervical pathologies observed. There were 55.2% (95% CI 49.7…60.8) of 21-24-year-olds and 57.1% (95% CI 53.6…60.6) of 25-29-year-old women who received HPV test not adherent to guidelines. CONCLUSIONS: Our findings highlighted some shortcomings in guideline adherence, especially among women under 30. The insights gained from this study help to improve the quality of care and, thus, reduce cervical cancer incidence and mortality.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

BACKGROUND: Uganda has approximately 1.2 million people aged 15-64 years living with human immunodeficiency virus (HIV). Previous studies have shown a higher prevalence of premalignant cervical lesions among HIV-positive women than among HIV-negative women. Additionally, HIV-infected women are more likely to have human papilloma virus (HPV) infection progress to cancer than women not infected with HIV. We determined the prevalence of premalignant cervical lesions and their association with HIV infection among women attending a cervical cancer screening clinic at Mbarara Regional Referral Hospital (MRRH) in southwestern Uganda. METHODS: We conducted a comparative cross-sectional study of 210 women aged 22-65 years living with HIV and 210 women not living with HIV who were systematically enrolled from March 2022 to May 2022. Participants were subjected to a structured interviewer-administered questionnaire to obtain their demographic and clinical data. Additionally, Papanicolaou smears were obtained for microscopy to observe premalignant cervical lesions. Multivariate logistic regression was performed to determine the association between HIV status and premalignant cervical lesions. RESULTS: The overall prevalence of premalignant cervical lesions in the study population was 17% (n = 72; 95% C.I: 14.1-21.4), with 23% (n = 47; 95% C.I: 17.8-29.5) in women living with HIV and 12% (n = 25; 95% C.I: 8.2-17.1) in women not living with HIV (p < 0.003). The most common premalignant cervical lesions identified were low-grade squamous intraepithelial lesions (LSIL) in both women living with HIV (74.5%; n = 35) and women not living with HIV (80%; n = 20). HIV infection was significantly associated with premalignant lesions (aOR: 2.37, 95% CI: 1.27-4.42; p = 0.007). CONCLUSION: Premalignant cervical lesions, particularly LSILs, were more common in HIV-positive women than in HIV-negative women, highlighting the need to strengthen the integration of cervical cancer prevention strategies into HIV care programs.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

Pap smears play a role in detecting extrauterine serous tumours in asymptomatic women. Certain cytopathologic and histopathologic findings combined with relevant clinical and radiologic findings indicate the possibility of primary peritoneal serous tumours. Cellblock immunohistochemistry is a valuable confirmatory diagnostic tool.

RESUMEN

OBJECTIVE: The introduction of cytological screening with the Papanicolau smear significantly reduced cervical cancer mortality. However, Pap smear examination can be challenging, being based on the observer ability to decode different cytological and architectural features. This study aims to evaluate the malignancy rate of AGC (atypical glandular cells) category, investigating the relationships between cytological and histological diagnosis. METHODS: Eighty-nine patients, diagnosed as AGC at cytological evaluation and followed up with biopsy or surgical procedure at Policlinico Gemelli Hospital, Rome, Italy, were included in the study. The cytopathological architectural (feathering, rosette formation, overlapping, loss of polarity, papillary formation, three-dimensional formation) and nuclear (N/C ratio, nuclear enlargement and hyperchromasia, mitoses, nuclei irregularity, evident nucleoli) features of AGC were evaluated. Statistical analyses were performed to assess cyto-histological correlation and determine the relevance of architectural and nuclear features in the diagnosis of malignancy. RESULTS: Of the 89 AGC patients, 48 cases (53.93%) were diagnosed as AGC-NOS and 41 (46.07%) were diagnosed as AGC-FN, according to the Bethesda classification system. The follow-up biopsies or surgical resections revealed malignancy in 46 patients (51.69%). The rates of malignancy for AGC-NOS and AGC-FN were 35.41% and 70.73% respectively. Furthermore, analysing cytopathological features, we found that both architectural and nuclear criteria were statistically significant (p < 0.05). Only overlapping, nuclear irregularity and increased N/C ratio were not found to be statistically significant for detecting malignancy. CONCLUSIONS: Cytological diagnosis of glandular lesions remains a valid tool, when appropriate clinical correlation and expert evaluation are available.

RESUMEN

We offer a comprehensive depiction of the cytomorphological characteristics of lobular endocervical glandular hyperplasia (LEGH) as observed in SurePath™ liquid-based cytology (LBC), subsequently confirmed on cone biopsy. Lobular endocervical glandular hyperplasia (LEGH), a precursor to gastric-type adenocarcinoma (GAE) of the endocervix, is rare and reports of it in cervical cytology are scarce. We provide a thorough description of the cytomorphological features of LEGH observed in SurePath™ liquid-based cytology (LBC), later confirmed by cone biopsy. To the best of our knowledge, this is the first report documenting cytology of LEGH in LBC of a Pap sample.

RESUMEN

INTRODUCTION: Specific diagnosis of endometrial carcinomas on cervical cytology is difficult with few useful cytomorphological clues reported. This study reviews a cohort of cervical cytology to investigate the presence of keratinization in atypical glandular cells (AGC), an undescribed cytomorphological clue for identifying endometrial endometrioid carcinomas on cervical cytology. METHODS: Cervical cytology slides from patients with a histologic diagnosis of endometrial endometrioid carcinoma were reviewed for the presence of keratinization associated with AGCs. Corresponding histology slides were reviewed for tumour grading and degree of squamous differentiation. RESULTS: In total, 42 cases of cervical cytology specimens from 41 patients were retrieved, including 7 (16.7%) with keratinization associated with AGCs seen and 35 (83.3%) without. Comparison of histologic grading did not demonstrate an association with the presence of keratinization on cytology (p = 0.565). Corresponding histology slides were available for 37 cases. Cytologic and histologic keratinization were associated statistically (p = 0.002). Frank keratinization was seen on histologic slides of five cases, with four also showing cytologic keratinization. Area of squamous differentiation, including squamous morule formation, did not correlate with keratinization on cytologic preparation (p = 0.185). CONCLUSION: Histologic and cytologic keratinization are observed in endometrioid endometrial carcinomas. Such is reflected in cervical cytology by the presence of orangeophilic, rigid and acellular fragments within or associated with AGC clusters. Keratinization, when identified with AGCs, should be regarded as a cytologic clue suggestive of an endometroid carcinoma of endometrial origin.

RESUMEN

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.

RESUMEN

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.
