Evaluation of nuclear morphometry in exfoliative cytology of buccal mucosa in patients with high risk of oral cancer.

BACKGROUND: Oral cancer poses a significant global health burden, with India having the highest prevalence. Effective detection is crucial in effective prevention. This study aimed to evaluate nuclear morphometric parameters (NMPs) in buccal mucosa cells of smokers, correlate NMPs with dysplasia, establish cut off values for grading dysplasia, and investigate the relationship between NMPs and smoking. METHODS: After obtaining ethical approval and informed consent, patients were recruited from the outpatient department of our institution. A target sample size of 250 was calculated. The data included smoking exposure quantified in pack-years, nuclear morphometric analysis (NMA) of buccal mucosa cells obtained through oral cytology using Image J, and the severity of dysplasia of the slides assessed by pathologists. Statistical analysis assessed the impact of dysplasia and the association between nuclear characteristics and smoking exposure. Receiver operating characteristic (ROC) plots determined the potential of these parameters to distinguish dysplasia levels. RESULTS: Significant differences in NMPs were observed among different smoking groups. Dysplasia severity had a significant correlation with NMPs, and strong correlations were found between NMPs and lifetime smoking exposure. ROC analysis established cut off values for NMPs with good sensitivity and specificity for classifying dysplasia severity. CONCLUSIONS: This study highlights the potential of NMA as a tool for oral cancer screening. NMPs can distinguish dysplasia severity and correlate with tobacco (smoking). The efficiency of NMA in a non-invasive oral cytology offers promise for patient-centered screening Additionally, the findings suggest future applications in telepathology and the potential for AI integration in automated screening after conducting multicentric large-scale studies.

Low uptake of Pap test as a cervical cancer screen among Saudi women: Findings from a national survey.

OBJECTIVE: The present study aimed to assess the current knowledge and uptake of Papanicolaou (Pap) tests for cervical screening among Saudi women, including barriers to undergoing the test and the availability of related services. METHODS: A cross-sectional study was conducted using a health questionnaire administered through the Absher portal between April 1, 2019, and March 31, 2020. The questionnaire consisted of five questions and took less than 5 min to complete. Descriptive and inferential statistics were employed to analyze demographic variables, and chi-square tests were used to examine the association between these variables and Pap test uptake. RESULTS: The questionnaire included 8194 Saudi women, with the majority from Makkah (24.40%), Riyadh (21.92%), and Eastern (14.44%) regions. Only 22.52% of respondents had ever received a Pap test, and among them, 17.48% did so based on their physician's recommendation. Private clinics accounted for 10.73% of Pap test locations, while public clinics accounted for 8.97%. The primary reasons for not undergoing the test were lack of knowledge regarding its importance (40.24%) and lack of information from physicians (16.96%). Knowledge of the Pap test as a cervical screening method was significantly associated with marital status, Saudi region, and age group. CONCLUSIONS: This study revealed low awareness of the Pap test for cervical screening among Saudi women, particularly in younger age groups. Targeted educational initiatives are essential to increase awareness and emphasize the significance of regular screenings, especially among younger individuals, to enhance early detection and reduce the burden of cervical cancer in Saudi Arabia.

Primary peritoneal low-grade serous carcinoma detected in cervical smear: Pitfalls mitigated by clinicocytopathologic clues and cellblock immunocytochemistry.

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.

Cervical cancer screening barriers and facilitators from the perspectives of women with a history of criminal-legal system involvement and substance use.

BACKGROUND: The wide availability of routine screening with Papanicolaou (Pap) tests and vaccinations against human papillomavirus has resulted in a decline in rates of cervical cancer. As with other diseases, however, disparities in incidence and mortality persist. Cervical cancer, is found more often, at later stages, and has worse outcomes in people who live in rural areas, identify as Black or Hispanic, and in people who are incarcerated. Studies report 4-5 times higher rates of cervical cancer incidence in people detained in jails and prisons than in community-based samples. Studies to explain cervical cancer differences have been inconclusive, though there is broad consensus that issues of access play a role. In this study, we sought to learn more from people who have a history of criminal-legal system involvement and substance use about what barriers and facilitators they perceive in accessing cervical cancer preventive health and other support services in the community. RESULTS: We conducted semi-structured interviews with open-ended questions by telephone with 20 self-identified women, ages 22-58, in Birmingham, Alabama. Interviews were audio recorded and transcribed and the transcripts analyzed using immersion-crystallization techniques. Our team identified two main themes, making connections: the importance of interpersonal communication, which stressed barriers and facilitators related to what makes for effective and humanistic interactions in cervical health prevention and other services, and getting it done: the logistics of access and availability, which highlighted elements of cost and payment; scheduling; transportation; and clinic policies. CONCLUSIONS: People with a history of criminal-legal system involvement and substance abuse meet with a variety of enabling and impeding factors at personal and interpersonal as well as systemic levels in obtaining cervical health services. To better ensure that women in this high-risk group have equitable access to cervical cancer prevention and treatment-and thus better cancer outcomes-will require multilevel efforts that include an emphasis on improving the human connection in health care encounters and improving the nuts-and-bolts logistics related to accessing that care.

Enhancing Cervical Cancer Screening: Review of p16/Ki-67 Dual Staining as a Promising Triage Strategy.

Cervical cancer, primarily caused by high-risk human papillomavirus (HR-HPV) types 16 and 18, is a major global health concern. Persistent HR-HPV infection can progress from reversible precancerous lesions to invasive cervical cancer, which is driven by the oncogenic activity of human papillomavirus (HPV) genes, particularly E6 and E7. Traditional screening methods, including cytology and HPV testing, have limited sensitivity and specificity. This review explores the application of p16/Ki-67 dual-staining cytology for cervical cancer screening. This advanced immunocytochemical method allows for simultaneously detecting p16 and Ki-67 proteins within cervical epithelial cells, offering a more specific approach for triaging HPV-positive women. Dual staining and traditional methods are compared, demonstrating their high sensitivity and negative predictive value but low specificity. The increased sensitivity of dual staining results in higher detection rates of CIN2+ lesions, which is crucial for preventing cervical cancer progression. However, its low specificity may lead to increased false-positive results and unnecessary biopsies. The implications of integrating dual staining into contemporary screening strategies, particularly considering the evolving landscape of HPV vaccination and changes in HPV genotype prevalence, are also discussed. New guidelines and further research are necessary to elucidate the long-term effects of integrating dual staining into screening protocols.

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.

Atypical glandular cells in Pap tests: cytology-histology correlation and risk assessment with human papillopmavirus (HPV) testing.

INTRODUCTION: Atypical glandular cells (AGC) represent less than 1% of Pap test cases and include a variety of lesions in both the cervix and endometrium. The study aimed to investigate the cytology-histology correlation in AGC patients and to evaluate the clinical utility of hrHPV testing in this diagnostic context. MATERIALS AND METHODS: We identified 491 atypical glandular cells (AGC) cases in our quality analysis (QA) database of 336,064 Pap tests interpreted between March 1, 2013 and July 12, 2016. Of these, 251 cases had follow-up biopsies with hrHPV tests in 148 cases. RESULTS: The most common histologic diagnosis associated with AGC was normal/benign or low-grade lesions, comprising 55% of cervical biopsies and 24% of endometrial biopsies. High-grade lesions were identified in 21% of follow-up biopsies. In patients with AGC cytology, a positive hrHPV test significantly increased the likelihood of cervical HSIL or above lesions on biopsy by 26.4 times (OR = 26.4, 95% CI: 5.8-119.4, P < 0.0001). A positive genotyping result for HPV 16 dramatically increased the likelihood of cervical HSIL or above lesions on biopsy (OR = 84, 95% CI: 12.0-590.5, P < 0.0001). The HPV test had a negative predictive value of 97% (CI: 85%-100%). CONCLUSIONS: Our study confirms that AGC is a significant diagnosis with an overall risk for high-grade cervical or endometrial lesions as high as 21%. hrHPV testing with genotyping is an effective tool for identifying high-risk individuals within the AGC population, with excellent positive and negative predictive values. This approach is valuable for clinical risk stratification and differential diagnosis in patients with AGC cytology.

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.

Predictive Value of Various Atypical Cells for the Detection of Human Papillomavirus in Cervical Smears.

It is thought that numerous genotypes of human papillomavirus (HPV) are associated with various atypical cells, such as multinucleated cells, koilocytes, binucleated cells, parakeratotic cells, and giant cells, in the cervix. We previously showed the specificity of HPV genotypes for koilocytes and multinucleated cells. Therefore, in this study, we analyzed the association among HPV genotypes and binucleated cells, parakeratotic cells, and giant cells in Papanicolaou (Pap) smears. We detected HPV genotypes and atypical cells in 651 cases of liquid-based cytology with an abnormal Pap smear. The HPV genotypes associated with atypical cells were evaluated using stepwise logistic regression with backward elimination and a likelihood ratio test for model construction. Polymerase chain reaction was used to determine the HPV genotypes in whole liquid-based cytology samples and microdissected cell samples from Pap smear slides. Binucleated cells were significantly associated with HPV genotype 42. Moreover, parakeratotic cells were significantly associated with certain HPV genotypes, such as HPV40. However, it was difficult to detect specific HPV genotypes by the manual microdissection-polymerase chain reaction method despite the presence of binucleated cells and parakeratotic cells. Thus, the presence of binucleated cells, parakeratotic cells, and giant cells in Pap smears may not be predictive of cervical lesions above low-grade squamous intraepithelial lesions or infection with highly carcinogenic HPV genotypes.

The WHO system versus the Papanicolaou society of cytopathology system for reporting pancreaticobiliary cytology for risk stratification-which is better?

BACKGROUND: Recently, the World Health Organization (WHO) has proposed a reporting system for pancreaticobiliary cytopathology. We applied this classification for pancreatic lesion samples by fine needle aspiration (FNA) and compared the results to the previous classification of the Papanicolaou Society of Cytopathology (PSC) system for risk stratification. METHODS: The computerized database was searched for all pancreatic endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) and transabdominal ultrasound-guided FNA (TUS-FNA) samples from 2016 to 2020 and cases were reassigned as per the PSC and the WHO diagnostic categories. Cases with follow-up, clinicoradiological, and/or histopathology were included in the study. The risk of malignancy (ROM) was calculated across all diagnostic categories based on clinical data, imaging data, and histopathology wherever available. RESULTS: There were a total of 625 pancreatic FNA. In 230 cases, follow-up information was available which included 116 EUS and 114 TUS-FNA samples. The ROM for PSC categories I-VI was 40%, 19.7%, 28.6%, 57.1%, 94.7%, and 97.9% and for the WHO categories (I-VII), it was 60%, 21.3%, and 35.7%, not representative, not applicable, 94.7% and 94.9%. The overall sensitivity and specificity of PSC was 68.2% and 96.2% when categories V and VI were taken as positive and 78.9% and 93.3% for WHO when categories VI and VII were taken as positive. CONCLUSIONS: Pancreatic FNA samples reported as per the WHO system showed better sensitivity as compared to the PSC system resulting in better risk stratification and consequently better patient management. The overall high specificity and moderate sensitivity reaffirm the utility of FNA in pancreatic lesions.

Endometrial Secrets Unmasked through Cytology Analysis.

Background: Endometrial aspiration (EA) is an economic, painless technique on an outpatient basis. Present study aimed at cytological evaluation of EA for (a) cellular yield and morphology and (b) utility of cell block (CB) and cytocentrifuge (CC) techniques. Materials and Methods: EA samples were divided into two aliquots. Colorless samples were processed (1000 rpm × 6 min) for conventional smear (CS) and CC, both stained by Papanicolaou. Hemorrhagic samples were processed for CS and CB (paraffin embedding, hematoxylin-eosin stain). Results: Endometrial aspirates from January 2021 to January 2022 were included. Indications comprised abnormal uterine bleeding (AUB; 87), prolapse (eight), and infertility (two). Among 77 hemorrhagic aspirates, the yield was 85.7% by CS and 90.9% by CB. Among 20 colorless aspirates, the yield was 55% by CS and 65% by CC. The yield was 85.7%, 84.4%, and 83.3% with endometrial thickness 1-5, 6-10, and 11-15 mm, respectively. The yield was 83.9%, 50%, and 0% in AUB, prolapse, and infertility, respectively. CS morphology showed the categories of benign (93.5%) and atypia (6.5%). All cases with benign morphology correlated with CB and CC. CB offered architectural evaluation, while CC had a shorter turnaround time. Conclusion: Focusing on menorrhagia cases in secretory phase, nondilution of EA samples, and simultaneous endometrial biopsy can enhance cytology evaluation. In an era where "less should convey more," EA shows potential as a screening technique vis-à-vis invasive "dilatation-curettage" technique.

Efficacy of Cobas HPV testing for predicting grade 2+ cervical intraepithelial neoplasia in a cancer prevention center and a gynecologic oncology clinic: A single-institution experience.

BACKGROUND: To evaluate the efficacy of Cobas human papillomavirus (HPV) testing to predict cervical intraepithelial neoplasia of grade 2 or higher (CIN2+), Cobas HPV testing results were correlated with follow-up biopsy in patients from Cancer Prevention Center (CPC) and Gynecologic Oncology Clinic (GOC) of The University of Texas MD Anderson Cancer Center. METHODS: Institutional data for patients who underwent Cobas HPV and Papanicolaou (Pap) cytology cotesting from 2019 to 2020 were retrospectively reviewed. Surgical follow-up results were compared with Cobas HPV testing results in two populations. RESULTS: A total of 2226 patients, including 921 women (mean age, 55.2 years) seen at the CPC and 1305 women (mean age, 49.3 years) seen at the GOC, were included. Specimens from GOC patients had a significantly higher HPV positivity rate than did those from CPC patients (22.9% vs. 10.1%; p < .001). Cobas HPV testing was positive in all seven CPC patients with surgical follow-up results showing CIN2+. Among 36 GOC patients with CIN2+ lesions, five patients had HPV-/Pap+ testing results. Although only seven CPC patients had CIN2+, Cobas HPV testing showed 100% sensitivity for predicting CIN2+ in this group. Sensitivity for CIN2+ was 86.5% in the GOC group, whereas 13.9% of GOC patients with CIN2+ had negative HPV testing results. CONCLUSIONS: Cobas HPV testing was highly efficacious for predicting CIN2+ lesions in the low-risk CPC population, which supports HPV primary screening for cervical cancer in low-risk populations. For high-risk patients, especially those with a history of CIN2+/cervical cancer, HPV/Pap cotesting may still be necessary to maintain a high clinical sensitivity for CIN2+.

Predictors of non-adherence to cervical cancer screening among immigrant women in Ontario, Canada.

Cervical cancer is one of the most common types of cancer among women and is largely preventable with regular screening using Papanicolau (Pap) tests. In Canada, all provinces have regular screening programs, although with slightly differing recommendations. Previous research has found that immigrant women, who are a large proportion of the Canadian population, are at higher risk of being under-screened, or non-adherent to the recommended screening frequency. Using data from the 2017 Canadian Community Health Survey, this study examined: (1) the extent to which immigration status and time since immigration are associated with Pap test adherence in Ontario, and (2) predictors of Pap test adherence for immigrants and Canadian born populations in Ontario, Canada's most populous province, with a focus on the role of racial or ethnic identity among immigrants. Estimates of 3-year test adherence were 71.3 % (95 %CI: 66.9-75.7) among immigrant women and 75.4 % (95 %CI: 73.1-77.1) among non-immigrant women. Recent immigrants (6-10 years in Canada) had lower adherence (63.5 %, 95 %CI: 48.0-80.0). Logistic regression models found that immigrant women had lower adherence than Canadian-born women, controlling for age, household income, education, and having a primary care physician. Subgroup analysis found that South Asian immigrant women were least likely to be adherent. These results support targeted programming to increase screening adherence among recent immigrants and raise concerns regarding potential barriers to screening. Data that allow better disaggregation of racial and ethnic identities are important for better understanding the potential implications of these patterns for racial inequities in health.

Implementation rate and related factors of confirmatory tests following an abnormal Pap smear: a nationwide study from the National Health Insurance.

OBJECTIVE: This study aims to investigate the implementation rate and influencing factors of confirmatory tests for women with abnormal cervical cytology results in the Korean nationwide cervical cancer screening program. METHODS: The National Health Insurance Service (NHIS) database was utilized to identify all Korean women who have participated in the Korean nationwide cervical cancer screening program from January 2011 and December 2021 using the NHIS database. Multiple logistic regression analysis was performed to estimate the multivariate odds ratio and evaluate the patients' characteristics. RESULTS: The rate of abnormal Papanicolaou (Pap) smears showed an initial increase from 2011 to 2015 and subsequently reached a plateau after 2016. When examining specific subcategories, cases of atypical squamous cells of undetermined significance (ASC-US) increased from 28,546 cases (1.1%) in 2011 to 62,850 cases (1.7%) in 2021. In contrast, cases of HSIL and SCC declined from 3,535 cases (0.14%) to 2,763 cases (0.07%) and from 383 cases (0.01%) to 179 cases (0.005%), respectively. Furthermore, the implementation rate of confirmatory tests for women with abnormal cytology increased from 8,865 cases (21.0%) in 2011 to 39,045 cases (51.2%) in 2021. Regarding the specific subcategory of ASC-US, the number of confirmatory tests exhibited a substantial increase from 4,101 cases (14.4%) in 2011 to 30,482 cases (48.5%) in 2021. For SCC, there was no significant change, with 216 cases (56.4%) in 2011 and 102 cases (57.0%) in 2021. The implementation rate of confirmatory tests was found to be significantly associated with results of abnormal Pap smear, age, and residence. Notably, economic status did not emerge as a significant factor affecting the likelihood of undergoing confirmatory tests. CONCLUSIONS: The severity of abnormal Pap smear results is a reliable indicator of the probability of undergoing a confirmatory test. Additional endeavors are required to improve the implementation rate among women who have received abnormal Pap smear results.

Self-reported participation in cervical cancer screening among Polish women in 2004-2019.

OBJECTIVES: We aimed to assess self-reported participation in cervical cancer screening among Polish women between 2004 and 2019 and to identify the groups with the lowest participation rate. MATERIAL AND METHODS: Data on declared participation in cervical cancer screening were obtained from the European Health Interview Survey from 2004 to 2019. RESULTS: In 2019, 86.7% of Polish women aged ≥ 15 years declared that they had ever undergone a Pap test. Compared to 2004, the coverage of ever-screened women improved by 16.6 percentage points. The proxy population coverage was 72.9%. The highest proportion of women who underwent a Pap smear in the last three years was observed among those aged 35-44 years and 25-34 years (84.0% and 83.2%, respectively), and the lowest among women aged ≥ 75 years (20.5%). The proportion screened within the last three years also varied by education (up to lower secondary education 26.4%, up to post-secondary non-tertiary education 62.8%, and the highest level of education 83.7%), urbanization (large cities 66.7%, suburbs, and smaller cities 62.8%, and rural areas 59.0%), income (poorest households 42.5%, wealthiest households 70.6%), and declared health status (best 68.9%, worst 41.4%). The lowest participation in screening was observed in the southeastern regions and the highest in the northwestern regions of Poland. CONCLUSIONS: In Poland, in 2019, the approximate coverage of cervical cancer screening was high compared to other European countries and has improved over the last 15 years. A complete screening registry is required to confirm questionnaire-based self-reported data. Targeted interventions should be implemented to address low participation in the identified regions and socioeconomic groups.

Underestimated Cervical Cancer among Women over 65 Years Old: Is It Time to Revise the Screening Target Age Group? / Câncer cervical subestimado entre mulheres com mais de 65 anos: É hora de rever a faixa etária alvo do rastreamento?

Abstract Objective To compare cytological and histological results from women > 64 years old who followed the Brazilian national cervical cancer screening guidelines with those who did not. Methods The present observational retrospective study analyzed 207 abnormal cervical smear results from women > 64 years old in a mid-sized city in Brazil over 14 years. All results were reported according to the Bethesda System. The women were divided into those who followed the screening guidelines and those who did not. Results Atypical squamous cells of undetermined significance and low-grade squamous intraepithelial lesion cytology results were found in 128 (62.2%) cases. Of these, 112 (87.5%) had repeated cytology with positive results. The other 79 (38.1%) with abnormal results should have been referred to colposcopy and biopsy. Out of 41 (51.9%) biopsied women, 23 (29.1%) had a confirmed diagnosis of neoplasia or precursor lesion. In contrast, among the 78 (37.7%) biopsied patients, 40 (51.3%) followed the guideline recommendations, with 9 (22.5%) positive biopsies. Of the 38 (48.7%) women who did not follow the guidelines, there were 24 (63.1%) positive results. Women who did not follow the guidelines demonstrated higher chances of cancer and precursor lesions (odds ratio [OR]: 5.904; 95% confidence interval [CI]: 2.188-15.932; p = 0.0002). Conclusion Women > 64 years old who did not follow the national screening protocol showed significant differences in the frequency of abnormal results and severity of diagnosis compared with those who followed the protocol.

Resumo Objetivo Comparar os resultados citológicos e histológicos de mulheres > 64 anos que seguiram as diretrizes nacionais brasileiras de rastreamento do câncer do colo do útero com aquelas que não as seguiram. Método O presente estudo observacional retrospectivo analisou 207 resultados anormais de esfregaço cervical de mulheres > 64 anos de idade em uma cidade de médio porte no Brasil durante 14 anos. Todos os resultados foram relatados de acordo com o Sistema Bethesda. As mulheres foram divididas entre as que seguiram as diretrizes de rastreamento e as que não o fizeram. Resultados Resultados citológicos com células escamosas atípicas de significado indeterminado e lesão intraepitelial escamosa de baixo grau foram encontrados em 128 (62,2%) casos. Destes, 112 (87,5%) repetiram a citologia com resultados positivos. Os outros 79 (38,1%) com resultados anormais deveriam ter sido encaminhados para colposcopia e biópsia. Das 41 (51,9%) mulheres biopsiadas, 23 (29,1%) tiveram diagnóstico confirmado de neoplasia ou lesão precursora. Em contrapartida, entre as 78 (37,7%) pacientes biopsiadas, 40 (51,3%) seguiram as recomendações da diretriz, com 9 (22,5%) biópsias positivas. Entre as 38 (48,7%) mulheres que não seguiram as orientações, houve 24 (63,1%) resultados positivos. As mulheres que não seguiram as diretrizes demonstraram maiores chances de câncer e lesões precursoras (odds ratio [OR]: 5,904; intervalo de confiança [IC] de 95%: 2,188-15,932; p = 0,0002). Conclusão Mulheres > 64 anos que não seguiram a diretriz nacional de rastreamento apresentaram diferenças significativas na frequência de resultados anormais e gravidade do diagnóstico em comparação com aquelas que seguiram a diretriz.

Cervical HPV Infections, Sexually Transmitted Bacterial Pathogens and Cytology Findings-A Molecular Epidemiology Study.

Prevalent cervical HPV infection and high-risk HPV persistence consequences have been extensively investigated in the literature; nevertheless, any causative interrelations of other sexually transmitted bacterial infections (STIs) with cervical HPV infection have not yet been fully elucidated. This study aimed to investigate the possible association of STIs with cervical cytology aberrations and HPV genotyping results in a representative sample of predominantly young Greek women. Liquid-based cytology and molecular detection for bacterial STIs and HPV as well as extended HPV genotyping were simultaneously assessed in cervical samples from 2256 individuals visiting several urban outpatient Gynecology Departments for well-woman visits or cervical screening throughout a 20-month period. All specimens were centrally processed with validated molecular assays. The mean age of the studied women was 37.0 ± 11.7 years; 722 women (33.30%) tested positive for STI (mean age 34.23 ± 10.87 years). A higher mean age (38.34 ± 11.83 years (p < 0.05)) was associated with negative STI testing. Chlamydia trachomatis was detected in 59 individuals (8.2%), Mycoplasma hominis in 156 (21.6%), Mycoplasma genitalium in 14 (1.9%), and Ureaplasma spp. in 555 (76.9%); infections with two bacterial pathogens were identified in 73 samples (10.1%). Cervical HPV was detected in 357 out of 1385 samples with a valid HPV typing result (25.8%). The mean age of HPV-positive women was 32.0 ± 8.4 years; individuals testing HPV-negative were slightly older (N = 1028): 34.4 ± 9.2 (p < 0.05). Among the 1371 individuals with valid results both for bacterial STIs and cervical HPV detection, women with an HPV-positive sample were more likely to harbor an STI (OR: 2.69, 95% CI 2.10-3.46, p < 0.05). Interestingly, bacterial STI positivity illustrated significant heterogeneity between NILM and LSIL cases, with 28.88% of NILM and 46.33% of LSIL cases harboring an STI, respectively (p < 0.05). In brief, in a population with a high prevalence for STIs, especially Ureaplasma spp., an association was documented between bacterial pathogen detection and cervical HPV infection, as well as abnormal cytology; these findings merit further investigation.
