Abstract
Human papillomavirus (HPV) is the most common sexually transmitted pathogen that causes anogenital disease. Cervical screening by cytology and HPV testing (co-testing) are important in prevention of cervical cancer. The Bethesda System category of atypical squamous cells (ASC) is used when a neoplastic process cannot be confidently identified. In such cases, the differential diagnosis is broad and includes benign conditions. Monitoring of ASC/SIL ratio is a commonly used laboratory quality assurance measure to prevent over- or under-use of this category. High risk human papillomavirus (hr-HPV) has been used in conjunction with the ASC/SIL ratio in determining whether a particular pathologist is over/under-using the indefinite category. However, the laboratory overall sample population prevalence rate of hr-HPV subtypes has not been previously examined for association with the ASC rate. In this study, the relationships between ASC/SIL ratio and hr-HPV prevalence rate and hr-HPV subtypes (16/18 and non-16/18) to the laboratory ASC prevalence were studied. The results demonstrate that HPV non-16/18 is the main subtype which is associated with ASC-US category. A large proportion of non-16/18 HPV-related cases are seen in young patients, which largely abates by the by fourth decade. In addition, there are differences in the ASC/SIL ratio for HPV 16/18 and non-16/18 types. The overall ASC/SIL ratio is an average of the ASC/SIL rate for the non-16/18 population and the HPV 16/18 population. Instead of basing the laboratory and practitioners' quality indicator solely on ASC/SIL ratio, the overall prevalence of HPV and its subtype ratio should also be reported as they are more reflective of laboratory performance.

Abstract
Cervical cancer ranks as the third most common female cancer in Cape Verde and is the leading cause of cancer-related deaths among women in the country. While Human Papillomavirus (HPV) vaccination, which started in 2021, is anticipated to significantly reduce disease incidence, cervical screening remains crucial for non-vaccinated women. We retrospectively reviewed gynecologic cytology exams and HPV tests performed in Cape Verde between 2017 and April 2023 and processed at IMP Diagnostics. For this study, we considered 13035 women with cytology examinations performed and, 2013 of these, also with an HPV molecular test. Cytology diagnostics comprised 83% NILM cases; 12% ASC-US; 2.7% LSIL; 1.2% ASC-H; 0.5% HSIL and 0.1% SCC. In 505 (25.1%) high-risk HPV infection was detected. Prevalence of HPV infection varied with age, peaking at young ages - ≤24 years old (55.5%) and 25-35-year-old women (31.5%) - and the lowest after 66 years old (9.7%). Herein we present a comprehensive study regarding Cape Verde's cervical cytology and HPV distribution, aiming to provide a snapshot of the country's cervical cytology results and HPV distribution in recent years. Moreover, these data may contribute to establish a baseline to assess, in the future, the vaccination impact in the country.

Abstract
(1) Background: The prediction of cervical lesion evolution is a challenge for clinicians. This prospective study aimed to determine and compare the predictive accuracy of cytology, HPV genotyping, and p16/Ki67 dual staining alone or in combination with personal risk factors in the prediction of progression, regression, or persistence of cervical lesions in human papillomavirus (HPV)-infected patients; (2) Methods: This prospective study included HPV-positive patients with or without cervical lesions who underwent follow-up in a private clinic. We calculated the predictive performance of individual tests (cervical cytology, HPV genotyping, CINtecPlus results, and clinical risk factors) or their combination in the prediction of cervical lesion progression, regression, and persistence; (3) Results: The highest predictive performance for the progression of cervical lesions was achieved by a model comprising a Pap smear suggestive of high-grade squamous intraepithelial lesion (HSIL), the presence of 16/18 HPV strains, a positive p16/Ki67 dual staining result along with the presence of at least three clinical risk factors, which had a sensitivity (Se) of 74.42%, a specificity of 97.92%, an area under the receiver operating curve (AUC) of 0.961, and an accuracy of 90.65%. The prediction of cervical lesion regression or persistence was modest when using individual or combined tests; (4) Conclusions: Multiple testing or new biomarkers should be used to improve HPV-positive patient surveillance, especially for cervical lesion regression or persistence prediction.

Abstract
BACKGROUND Abnormal cervical cytology is commonly observed in women living with HIV (WLWH). METHODS A cross-sectional study was conducted with 130 WLWH and 147 age-matched healthy controls, who underwent gynecological examinations at Beijing Ditan Hospital. The presence of abnormal cervical cytology in WLWH was predicted after performing a logistic regression analysis. RESULTS Multivariate logistic regression revealed three independent factors, among which CD4 cell counts of more than 350 cells/μL was the protective factor, while human papillomavirus infection and abnormal vaginal pH were the risk factors. CONCLUSIONS Vaginal microecological disorders can increase the risk of abnormal cervical cytology in WLWH.

Abstract
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.

Abstract
BACKGROUND/AIM Among the four genomic subtypes of endometrial cancer, distinguishing between the DNA polymerase epsilon mutation (POLEmut) and no specific molecular profile (NSMP) subtypes requires genomic profiling owing to the lack of surrogate immunohistochemical markers. We have previously found that, histologically, the POLEmut-subtype exhibits surface epithelial slackening (SES). Therefore, to improve subtype identification, we aimed to extract cytological features corresponding to SES in POLEmut-subtype cervical cytology specimens. MATERIALS AND METHODS We analyzed 104 endometrial cancer cervical cytology specimens, with integrative diagnosis confirmation via histology, immunohistochemistry, and genomic profiling. Cytological features were evaluated for the presence of atypical glandular cells, atypical cell appearance in single cells and clusters, and cytological SES and the presence of tumor-infiltrating inflammatory cells in clusters. RESULTS Based on cervical cytology, the POLEmut- and p53mut-subtypes exhibited more frequent atypical cells in smaller clusters, giant tumor cells, and cytological SES patterns than the NSMP-subtype. Tumor-infiltrating lymphocytes were frequent in the POLEmut- and mismatch repair-deficient subtypes. CONCLUSION Histologically-detected SES as well as other endometrial cancer features may be preserved in the atypical cell clusters observed in cervical cytology specimens. Cytological detection of SES and of smaller clusters of atypical cells and inflammatory cells with moderate atypia are suggestive of POLEmut-subtype. Integrative diagnosis including genomic profiling remains critical for diagnostic confirmation.

Abstract
Background High-risk human papillomavirus (HR-HPV) is the primary cause of cervical cancer, leading to over 311 000 global deaths, mainly in low- and middle-income countries. Kenyan women living with HIV (WLHIV) face a disproportionate burden of HR-HPV. Objectives We determined the prevalence of HR-HPV infections and their association with cervical cytology findings among Kenyan WLHIV. Method We conducted a cross-sectional study among WLHIV attending the HIV care and treatment clinic at the Kenyatta National Hospital (KNH), Kenya's national referral hospital. Study nurses collected a cervical sample with a cytobrush for HR-HPV genotyping using Gene Xpert® assays and HPV Genotypes 14 Real-TM Quant V67-100FRT. Bivariate analysis explored the associations. Results We enrolled 647 WLHIV (mean age of 42.8 years), with 97.2% on antiretroviral therapy (ART) and 79% with a suppressed viral load (< 50 copies/mL plasma). The prevalence of any and vaccine-preventable HR-HPV was 34.6% and 29.4%, respectively, with HPV 52 being the most common genotype (13.4%). Among WLHIV with HR-HPV infections, 21.4% had abnormal cervical cytology. Women with multiple HR-HPV infections were more likely to have abnormal cytology compared to those with single HR-HPV infections (34.9 vs 9.3%, adjusted odds ratio [aOR] = 6.2, 95% confidence interval [CI]: 2.7-14.1, P = 0.001). Women with HR-HPV infection (single or multiple) were more likely to be on the second-line ART regimen compared to those without HR-HPV infections (53.1% vs 46.7%, aOR = 2.3, 95% CI: 1.3-4.1, P = 0.005). Conclusion Among WLHIV at KNH, abnormal cytology was common and more frequent among women with multiple HR-HPV infections.

Abstract
OBJECTIVE The Papanicolaou (Pap) smear test is a standard screening test that detects cervical lesions and cancers. In this multicentric study, we performed a retrospective analysis of cytological results associated with atypical glandular cells, not otherwise specified (AGC-NOS). METHODS We retrospectively reviewed Pap smear tests that resulted as AGC-NOS. A total of 254 women who underwent colposcopy due to a Pap smear result of AGC-NOS were included the study between 2003 and 2021. The ages, Pap smear results, HPV results if any, colposcopic biopsy results, endocervical and endometrial pathology results, and management of these patients were analysed. RESULTS Two hundred fifty-four patients with AGC-NOS Pap smear results were included in the study. A total of 70 (27.6%) patients had cervical and endometrial premalignant or malignant lesions. Malignancy was observed in 17 (6.7%) patients (endometrium, n = 11 [4.3%]; cervix, n = 6 [2.4%]). Isolated premalignant or malignant lesions of the cervix and endometrium were detected in 57 (22.4%) and 12 (4.7%) patients, respectively. CONCLUSIONS Patients diagnosed with AGC-NOS should undergo a careful evaluation with all clinicopathological features. Because cancer of the cervix and endometrium is not rare in patients diagnosed with AGC-NOS, colposcopic examination with endocervical sampling should be a priority based on a cervicovaginal smear. Endometrial sampling is also required according to the patient's clinic, age, and examination characteristics.

Abstract
The project named Victoria's cells was created to train health care personnel, especially in low-income countries. This innovative approach is designed to associate benign and malignant cellular images and/or patterns with a range of shapes and color shades to evoke animals, common objects, and colorful aquariums. The project makes use of familiar images to capture the viewer's interest as an aid for cytological interpretation. Cervicovaginal cytology is processed with conventional and liquid-based cytology. The images are visually compelling to highlight the importance of studying cells and their diagnostic significance. Infectious diseases as well as malignant cells are thereby easily recognized. The pictures are organized into different sections, including Victoria's zoo, Victoria's fantasy, and malignant mockery. Branching mycelia resemble a starfish; squamous metaplasia recalls a sea turtle's shell. Among others, different patterns of endometrial, endocervical, and squamous cells can resemble fish tanks populated by cells with the shapes of pufferfish, anglerfish, whales, scorpions, and garfish. The sea transitions to the earth, with a sly cat, a little elephant, a dog, and a koala. Other cellular preparations resemble a gymnast, a geisha, and a plunging diver as well as hummingbirds, a heron, a water lily, and a peony. The malignant mockery section is composed of squamous intraepithelial lesion patterns that resemble monsters, eyes, a foul tongue, eagles, and feathers. In conclusion, the recognition of visual images can make the study of cytology simpler and more enjoyable and serve the final objectives of prevention and cure.

Abstract
Background Human papillomavirus (HPV) infection is closely correlated with cervical lesions. However, the HPV prevalence varies among different districts. This retrospective study investigated the HPV genotype distribution and its relationship with cervical lesions in southern Hunan Province. Methods The database at our Pathology Department was searched for HPV and morphological results during 2018-2020 were reviewed. A total of 49,955 gynaecological inpatients and outpatients, each of whom underwent HPV testing based on the amplification of L1 sequence and reverse dot blot hybridization, were included in this study. Available cytology and relevant histological examination results were reviewed. Enrolled cases were categorized into seven groups based on their age. Household registry and educational level were evaluated. Results Seven thousand two hundred eighty-six females were positive for HPV and the overall HPV positivity rate was 14.59%. The top five most prevalent HPV genotypes were HPV52, 16, 58, 53 and 51 (22.98%, 17.54%, 14.29%, 7.47%, and 5.70%, respectively). The HPV prevalence curve specific to the seven age groups showed a bimodal distribution. High school education or blow and rural residence served as risk factors for HPV infection. Single infection was the main type of HPV infection, and multiple infections occurred in 21.92% of the infected women. Of 3,148 cases had cytological results, 1,149 (36.50%) had abnormal cytological abnormalities. Among 2,833 participants with histological examination, 2000 (70.60%) had cervical abnormalities. Cytological and pathological abnormalities were mainly associated with infection with HPV16, 52 and 58. Further analysis found that HPV16, 58, 52 and 33 were the main genotypes associated with high-grade squamous lesions (HSIL) and that HPV16, 31, 33 and 58 were independent risk factors for HSIL (odd ratio [OR] = 1.70, 1.99, 2.59, 2.29; 95% CI = 1.41-2.03, 1.17-3.41, 1.88-3.59, 1.85-2.82; all p < 0.05). HPV16, 58, 52, 18 and 33 were the most frequent genotypes detected in squamous cell carcinoma (SCC) patients, and HPV16 and 18 were independent risk factors for cervical carcinomas (OR = 6.72;95% CI = 5.48-8.25; p < 0.001; OR = 1.67, 95% CI = 1.22-2.30; p = 0.001). Conclusion This retrospective study demonstrated the prevalence and the distribution characteristics of HPV infection and its correlation with cervical lesions in southern Hunan Province. The comprehensive results of this survey can guide HPV vaccine research to protect against some common genotypes in China.

Abstract
Introduction Atrophy of the reproductive tract mucosa caused by the decrease of estrogen may increase the detection rate of ASC-US in cervical cytology of post-menopausal women. In addition, other pathogenic infections and inflammation can change the cellular morphology and increase the detection rate of ASC-US. However, further studies are needed to elucidate whether the high detection rate of ASC-US in post-menopausal women leads to the high referral rate of colposcopy. Methods This retrospective study was conducted to document ASC-US in cervical cytology reports at the Department of Cytology at Gynecology and Obstetrics, Tianjin Medical University General Hospital between January 2006 and February 2021. We then analyzed 2,462 reports of women with ASC-US at the Cervical Lesions Department. A total of 499 patients with ASC-US and 151 cytology with NILM participants underwent vaginal microecology tests. Results The average reporting rate of ASC-US in cytology was 5.7%. The detection rate of ASC-US in women aged > 50 years (7.0%) was significantly higher than that in women aged ≤50 years (5.0%) (P<0.05). The CIN2+ detection rate was significantly lower in the post- (12.6%) than in pre-menopausal (20.5%) patients with ASC-US (P <0.05). The prevalence of abnormal reporting rate of vaginal microecology was significantly lower in the pre-menopausal group (56.2%) than that in the post-menopausal group (82.9%) (P<0.05). The prevalence of bacterial vaginosis (BV) (19.60%) was relatively high in the pre-menopausal group, but the abundance of bacteria-inhibiting flora (40.79%) was mainly an abnormality in the post-menopausal group. The vaginal microecological abnormality rate of the women with HR-HPV (-) of ASC-US was 66.22%, which was significantly higher than that of the HR-HPV (-) and the NILM group (52.32%; P<0.05). Discussion The detection rate of ASC-US in women aged > 50 years was higher than that ≤50 years, but the detection rate of CIN2+ was lower in the post-menopausal women with ASC-US. However, vaginal microecological abnormalities may increase the false-positive diagnosis rate of ASC-US. The vaginal microecological abnormalities of the menopausal women with ASC-US are mainly attributed to infectious diseases such as BV, and it mainly occurs in the post-menopausal women was bacteria-inhibiting flora. Therefore, to avoid the high referral rate for colposcopy, more attention should be paid to the detection of vaginal microecology.

Abstract
Cervical cancer is one of the most common cancers that threaten women's lives, and its early screening is of great significance for the prevention and treatment of cervical diseases. Pathologically, the accurate segmentation of cervical cells plays a crucial role in the diagnosis of cervical cancer. However, the frequent presence of adherent or overlapping cervical cells in Pap smear images makes separating them individually a difficult task. Currently, there are few studies on the segmentation of adherent cervical cells, and the existing methods commonly suffer from low segmentation accuracy and complex design processes. To address the above problems, we propose a novel star-convex polygon-based convolutional neural network with an encoder-decoder structure, called SPCNet. The model accomplishes the segmentation of adherent cells relying on three steps: automatic feature extraction, star-convex polygon detection, and non-maximal suppression (NMS). Concretely, a new residual-based attentional embedding (RAE) block is suggested for image feature extraction. It fuses the deep features from the attention-based convolutional layers with the shallow features from the original image through the residual connection, enhancing the network's ability to extract the abundant image features. And then, a polygon-based adaptive NMS (PA-NMS) algorithm is adopted to screen the generated polygon proposals and further achieve the accurate detection of adherent cells, thus allowing the network to completely segment the cell instances in Pap smear images. Finally, the effectiveness of our method is evaluated on three independent datasets. Extensive experimental results demonstrate that the method obtains superior segmentation performance compared to other well-established algorithms.

Abstract
BACKGROUND Cervical cancer incidence and mortality in Estonia are among the highest in Europe, although the overall coverage with cervical cytology is high. This indicates potential issues with the quality of collection and/or laboratory evaluation of cervical cytology. OBJECTIVES The aim of the retrospective observational study was to assess the quality of cervical cytology specimen collection, evaluation, and reporting using laboratory reports in Estonia. METHODS The study included women with a cervical cancer diagnosis in 2017-2018. Cervical cytology and histology reports for these women in 2007-2018 were obtained from ten laboratories. We described the quality of cytology specimen collection and reporting of cytology results. Multivariate logistic regression was used to calculate odds ratios (OR) with 95% confidence intervals (CI) to identify factors associated with NILM as the last cervical cytology result within 5 or 2 years before the cervical cancer diagnosis. Also, we calculated cytology-histology correlation (CHC). RESULTS We identified 503 cytology and 100 histology reports from 138 women. The laboratories differed greatly regarding human resources, work capacity and volume. Differences between local and regional laboratories were observed in reporting specimen adequacy (P < .001). We found that local laboratories had 3 times higher odds (OR = 2.95, 95% CI: 1.05-8.33) of reporting normal results 2 years before cancer diagnosis than regional laboratories. According to the CHC, 58.9% of pairs were in agreement. CONCLUSIONS The study showed considerable heterogeneity and suboptimal performance of cervical cytology practices in Estonia, particularly at local laboratories. Efforts to improve laboratory quality assurance are crucial.

Abstract
BACKGROUND Although the incidence of cervical adenocarcinoma has consistently increased, especially among young women, there is no established best means for screening. This study evaluated the screening efficacy of CINtec PLUS (CINtec; p16/Ki67 double immunocytochemistry) expression in cervical glandular cells. METHODS Cervical cytology was examined using abnormal glandular cells. The CINtec status of 100 samples with corresponding surgically resected specimens and 11 samples that exhibited negative results for intraepithelial lesion or malignancy at follow-up was analyzed. Additionally, 31 negative samples containing benign glandular cells were included. RESULTS Of the 142 samples, CINtec status was diffusely positive in 74, focally positive in 24, and negative in 44. The 74 diffusely positive samples included 70 adenocarcinomas (62 cervical, seven uterine, and one ovarian) and four cases of high-grade cervical intraepithelial neoplasia. The 24 focally positive samples included 15 adenocarcinomas (seven cervical, seven uterine, and one fallopian tube) and nine without malignancy. The 44 negative samples included nine adenocarcinomas (five uterine and four cervical) and 35 without malignancy. The sensitivity, specificity, positive predictive value, and negative predictive value of the CINtec diffusely or focally positive cases for cervical adenocarcinomas were 94.5%, 58.0%, 70.4%, and 90.9%, respectively. In CINtec diffusely positive cases, the respective values were 84.9%, 82.6%, 83.8%, and 83.8%, and in women aged ≤39 years the values were 90.6%, 89.5%, 93.5%, and 85.0%, respectively. CONCLUSIONS CINtec may support efficient detection of cervical adenocarcinomas.

Abstract
OBJECTIVE This study was conducted to determine global DNA methylation patterns in cervical cells cytologically identified as atypical squamous cells of unknown significance (ASCUS) with a normal, LSIL, or HSIL histopathological result. METHODS Methylation patterns of long interspersed nuclear elements (LINE-1) and short interspersed element (Alu) sequences were assessed using the combined bisulfite restriction analysis (COBRA) method in cervical samples with cytology-diagnosed cervical lesions. RESULTS In cervical precancerous lesions with hrHPV positive, the percentage of overall (mC) and mCmC LINE-1 methylation levels showed a stepwise increase from hrHPV positive normal to HSIL with significant differences (p<0.001). However, both methylation levels were significantly higher in hrHPV negative normal than in hrHPV positive normal (p<0.001). The overall (mC) Alu methylation in hrHPV positive LSIL and HSIL was lower than in hrHPV positive normal, with a significant difference (p<0.05). Remarkably, the percentage of uCmC and mCuC of LINE-1 and Alu in three different hrHPV positive cervical lesions showed a stepwise decrease from hrHPV positive normal, LSIL and HSIL, respectively. Furthermore, receiver operating characteristic (ROC) curve analyses revealed that the LINE-1 mC and mCmC patterns have high sensitivity and specificity for distinguishing HSIL from normal/LSIL in hrHPV positive cases at the appropriate cutoff levels. CONCLUSION We have demonstrated the LINE-1 and Alu methylation data in normal and premalignant cervical epithelia. LINE-1 hypomethylation was found in hrHPV positive normal cells, with lower methylation levels associated with cancer features. In cytologically diagnosed Atypical Squamous Cells of Unknown Significance (ASCUS), the levels of mC and the mCmC pattern could be utilized in concert with hrHPV detection to classify the ASCUS sample prior to colposcopy.

Abstract
OBJECTIVE To evaluate the risk of false HPV negative results and possible related morphological abnormalities in HPV primary cervical cancer screening. METHODS Out of 53 661 HPV negative cases, 5469 (10.2%) randomly selected cytology slides were evaluated as a part of the quality assurance protocol. RESULTS The Bethesda category Negative for Intraepithelial Lesion or Malignancy (NILM) in the HPV negative cases given was present in 95.4%. Due to cytology other than NILM, 0.4% of cases were referred to colposcopy and 4.2% to the follow up in one year. In the follow up HPV negativity and NILM cytology was present in 88.3 % of attended women. Cases other than HPV negative and NILM were referred to colposcopy. One biopsy-proven histological HSIL was found in the first round and one in follow up screening. More comprehensive genotyping of HSIL cases revealed genotypes 69 and 11. CONCLUSIONS Only two HPV test negative cases with histological HSIL were revealed forming 0.04% of quality control group. In both cases, HPV genotype not included in screening tests was found. According to the results, the primary HPV test with cytology triage is an efficient and specific method for cervical cancer screening despite of the fact that some non-high-risk genotypes are missed.

Abstract
Introduction: Based on the experience from a Swedish biobank, we established a clinical cervical cytology biobank and adapted it to a Danish setting. The aim of the present study was to validate the biobank material regarding quality and quantity, to determine the usefulness of the material for future diagnostics and biomarker testing. Methods: Cervical cytology samples collected in ThinPrep were analyzed before and after biobanking using p16/ki-67 dual staining, a human papillomavirus (HPV) DNA test (Cobas), and a test for HPV messenger RNA (mRNA; Aptima). The concordance of the test results before and after biobanking was assessed. We also evaluated the morphology before and after biobanking and did additional tests on the biobanked material to qualify the usefulness of the material (library preparation for next-generation sequencing [NGS], reverse transcription-polymerase chain reaction [RT-PCR], and the Inno-Lipa HPV genotyping test). Results: For the Cobas HPV test, the concordance was 92% (122/133), and for the Inno-Lipa test (30 samples), it was 100%. For the Aptima assay, the concordance was a little lower, 84% (42/50). The morphology of the cell was well preserved, and the concordance of the p16/ki-67 dual staining was 88% (37/42). The functional tests showed that DNA-based NGS libraries (TST15 panel; Illumina) had good quality parameters. However, with the RT-PCR, 12% of the samples showed poor quality and a too low input amount for the analysis. Conclusion: The quality of the biobanked samples is high, and the material is suitable for testing of DNA, RNA, and protein. However, for testing of specific biomarkers, pilot studies are recommended to ensure sufficient input amount and quality of the material, especially for RNA-based studies.

Abstract
Simple Summary This review discusses the timeline and development of the recommended screening tests, diagnosis system, and therapeutics implemented in clinics for precancer and cancer of the uterine cervix. The incorporation of the latest automation, machine learning modules, and state-of-the-art technologies into these aspects are also discussed. Abstract Cancer arising from the uterine cervix is the fourth most common cause of cancer death among women worldwide. Almost 90% of cervical cancer mortality has occurred in low- and middle-income countries. One of the major aetiologies contributing to cervical cancer is the persistent infection by the cancer-causing types of the human papillomavirus. The disease is preventable if the premalignant lesion is detected early and managed effectively. In this review, we outlined the standard guidelines that have been introduced and implemented worldwide for decades, including the cytology, the HPV detection and genotyping, and the immunostaining of surrogate markers. In addition, the staging system used to classify the premalignancy and malignancy of the uterine cervix, as well as the safety and efficacy of the various treatment modalities in clinical trials for cervical cancers, are also discussed. In this millennial world, the advancements in computer-aided technology, including robotic modules and artificial intelligence (AI), are also incorporated into the screening, diagnostic, and treatment platforms. These innovations reduce the dependence on specialists and technologists, as well as the work burden and time incurred for sample processing. However, concerns over the practicality of these advancements remain, due to the high cost, lack of flexibility, and the judgment of a trained professional that is currently not replaceable by a machine.

Abstract
Objective This study was conducted to evaluate the status and role of cervical cytology affected by human papillomavirus infection and other infectious diseases screened during routine prenatal checkups. Methods We retrospectively examined medical records containing the screening results for infectious diseases and cervical cancer in women who delivered neonates in our hospital from 2014 to 2017. Results Among 3393 deliveries, 18.8% of women underwent a regular cervical cancer screening within 1 year of becoming pregnant, and 2641 women underwent a cervical cytology screening during this pregnancy. The cytological diagnostic results showed that 2562 women (97.0%) were negative for intraepithelial lesions or malignancy, whereas 79 (3.0%) had abnormal results. Of those with abnormal cytology results, 70 had abnormal cytology that was newly detected in this pregnancy, and 42 had grade ≥1 cervical intraepithelial neoplasia lesions. Spatulas were the most frequently used cytological sampling instruments, followed by cotton swabs. Cervical cytology revealed no major adverse reactions during these pregnancies. Conclusions Our results confirm the importance of screening for infectious diseases during pregnancy. Only 20% of the women underwent a regular pre-pregnancy cervical cytology screening. Cervical cytology screening during pregnancy may currently be playing a crucial role in preventing cervical cancer in Japan.

Abstract
OBJECTIVES Since 2006, the US human papillomavirus (HPV) vaccination program has led to decreases in HPV infections caused by high-risk vaccine-targeted HPV types (HPV 16/18). We assessed differences in high-risk HPV prevalence by cervical cytology result among 20- to 24-year-old persons participating in routine cervical cancer screening in 2015-2017 compared with 2007. MATERIALS AND METHODS Residual routine cervical cancer screening specimens were collected from 20- to 24-year-old members of 2 integrated healthcare delivery systems as part of a cross-sectional study and were tested for 37 HPV types. Cytology results and vaccination status (≥1 dose) were extracted from medical records. Cytology categories were normal, atypical squamous cells of undefined significance, low-grade squamous intraepithelial lesions (SIL), or high-grade SIL/atypical squamous cells cannot exclude high-grade SIL. Prevalences of HPV categories (HPV 16/18, HPV 31/33/45/52/58, HPV 35/39/51/56/59/66/68) were estimated by cytology result for 2007 and 2015-2017. RESULTS Specimens from 2007 (n = 4046) were from unvaccinated participants; 4574 of 8442 specimens (54.2%) from 2015-2017 were from vaccinated participants. Overall, HPV 16/18 positivity was lower in 2015-2017 compared with 2007 in all groups: high-grade SIL/atypical squamous cells cannot exclude high-grade SIL, 16.0% vs 69.2%; low-grade SIL, 5.4% vs 40.1%; atypical squamous cells of undefined significance, 5.0% vs 25.6%; and normal, 1.3% vs 8.1%. Human papillomavirus 31/33/45/52/58 prevalence was stable for all cytology groups; HPV 35/39/51/56/59/66/68 prevalence increased among low-grade SIL specimens (53.9% to 65.2%) but remained stable in other groups. CONCLUSIONS Prevalence of vaccine-targeted high-risk HPV types 16/18 was dramatically lower in 2015-2017 than 2007 across all cytology result groups while prevalence of other high-risk HPV types was mainly stable, supporting vaccine impact with no evidence of type replacement.

Abstract
BACKGROUND Although many cervical cytology diagnostic support systems have been developed, it is challenging to classify overlapping cell clusters with a variety of patterns in the same way that humans do. In this study, we developed a fast and accurate system for the detection and classification of atypical cell clusters by using a two-step algorithm based on two different deep learning algorithms. METHODS We created 919 cell images from liquid-based cervical cytological samples collected at Sapporo Medical University and annotated them based on the Bethesda system as a dataset for machine learning. Most of the images captured overlapping and crowded cells, and images were oversampled by digital processing. The detection system consists of two steps: (1) detection of atypical cells using You Only Look Once v4 (YOLOv4) and (2) classification of the detected cells using ResNeSt. A label smoothing algorithm was used for the dataset in the second classification step. This method annotates multiple correct classes from a single cell image with a smooth probability distribution. RESULTS The first step, cell detection by YOLOv4, was able to detect all atypical cells above ASC-US without any observed false negatives. The detected cell images were then analyzed in the second step, cell classification by the ResNeSt algorithm, which exhibited average accuracy and F-measure values of 90.5% and 70.5%, respectively. The oversampling of the training image and label smoothing algorithm contributed to the improvement of the system's accuracy. CONCLUSION This system combines two deep learning algorithms to enable accurate detection and classification of cell clusters based on the Bethesda system, which has been difficult to achieve in the past. We will conduct further research and development of this system as a platform for augmented reality microscopes for cytological diagnosis.

Abstract
Background The aim of the study was to evaluate the diagnostic accuracy of p16/Ki-67 dual immunostaining (p16/ Ki-67 DS) in cervical cytology and the number of positive p16/Ki-67 cells to diagnose high grade cervical intraepithelial neoplasia (CIN2+) in colposcopy population. Subjects and methods We performed an analysis on a subset cohort of 174 women enrolled within a large-scale randomised controlled human papillomavirus (HPV) self-sampling project organised as part of the population-based Cervical Cancer Screening Programme ZORA in Slovenia. This subset cohort of patients was invited to the colposcopy clinic, underwent p16/Ki-67 DS cervical cytology and had the number of p16/Ki-67 positive cells determined. Results Among analysed women, 42/174 (24.1%) had histologically confirmed CIN2+. The risk for CIN2+ was increasing with the number of positive cells (p < 0.001). The sensitivity of p16/Ki-67 DS for detection of CIN2+ was 88.1%, specificity was 65.2%, positive predictive value was 44.6% and negative predictive value was 94.5%. Conclusions Dual p16/Ki-67 immunostaining for the detection of CIN2+ has shown high sensitivity and high negative predictive value in our study, which is comparable to available published data. The number of p16/Ki-67 positive cells was significantly associated with the probability of CIN2+ detection. We observed a statistically significant and clinically relevant increase in specificity if the cut-off for a positive test was shifted from one cell to three cells.

Abstract
PURPOSE This study aims to validate the value of microRNA (miRNA) detection for triaging human papillomavirus (HPV)-positive women in the general population. PATIENTS AND METHODS miR-375 detection in cervical exfoliated cells has been demonstrated to have the superior value to cytology in triaging primary HPV-positive women in the hospital population. In this study, residual samples of cervical exfoliated cells from 10,951 women in a general population were used to detect miRNA. The performance efficiency of miRNA detection in identifying high-grade cervical intraepithelial neoplasia (CIN) was evaluated. Pearson chi-square test and McNemar pairing test were used to compare miRNA detection and cytology. RESULTS In valid 9,972 women aged 25-65, miR-375 expression showed a downward trend along with an increase in cervical lesion severity. The expression level of miR-375 ≤1.0 × 10-3 was identified as positive. In the HPV-positive and 12 HPV genotypes other than 16/18 (HR12)-positive women, miR-375 detection showed equivalent sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) to that of cytology (≥ASC-US) and higher or similar sensitivity and NPV but lower specificity and PPV than that of cytology (≥ASC-H) in identifying CIN3+ and CIN2+. In HPV 16-positive women, miR-375 positivity had higher sensitivity and NPV but lower specificity and PPV than that of cytology (≥ASC-H and HSIL) in identifying CIN3+ and CIN2+. The immediate CIN3+ risk of miR-375 positivity was 19.8% (61/308) in HPV-positive, 10.8% (22/204) in HR12-positive, and 43.5% (37/85) in HPV16-positive women, respectively. CONCLUSION The detection of miR-375 in cervical exfoliated cells may be an optional method for triaging primary HPV-positive women in population-based cervical cancer screening.

Abstract
AIM The aim of this study was to evaluate the clinical performance for detecting cervical intraepithelial neoplasia (CIN) 2 or higher lesions among available human papillomavirus infection (HPV) genotyping tests in Korea. METHODS Eligible patients visited 13 tertiary hospitals for colposcopic biopsy following cervical cytology and HPV genotyping test between January and December 2018. Baseline characteristics including age, body mass index (BMI), and parity were collected from 3798 patients. The performance of the Roche Cobas HPV 4800 was evaluated against other domestic HPV assays to detect CIN2 or higher. RESULTS A total of seven types of HPV genotyping tests were analyzed in the research institutes. A total of 1358 patients (35.8%) tested Anyplex II HPV 28 and 701 patients (18.5%) tested Cobas 4800 HPV. The overall sensitivity in the detection of CIN2 or higher was 41.5% (38.9-44.1) in patients positive for HPV 16/18. The Cobas test for HPV 16/18 was concordant with other assays evaluated for detection of CIN2 or higher and showed sensitivity of 46.6%, which was not significantly different from other assays. Although Anyplex II HPV28 (Seegene) showed slightly decreased sensitivity for detecting CIN2 or higher lesion with HPV 16/18 positive (39.8%, p < 0.05) compared to Cobas 4800, in aspect of high-risk HPV positive, Anyplex II HPV28 showed increased sensitivity (96.9%, p < 0.05). CONCLUSION The performance of the HPV genotype test that were commonly used in Korea was concordant with Cobas HPV test. Further studies are needed to evaluate the safety, efficiency, and cost-effectiveness of the various commercially available domestic HPV assays.

Abstract
INTRODUCTION Uterine clear cell adenocarcinoma (CCC) is a rare, aggressive malignancy with poor prognosis. The present study aimed to identify and describe its characteristic morphological features in cervical cytology. METHODS This was a 3-year retrospective case-control study. Cases included cervical samples of histopathologically proven endometrial and cervical CCC. Controls included cervical samples of histopathologically proven endometrial serous carcinoma (n = 15), endometrioid adenocarcinoma (n = 20), and endocervical adenocarcinoma (n = 15). Twenty-eight cytomorphological features were evaluated; the strength of association was determined by odds ratio (OR) and Cramer's V, and the diagnostic accuracy of statistically significant features was assessed. RESULTS Cases consisted of histopathologically proven 25 (34.7%) endometrial and 13 (18.0%) cervical CCC. Corresponding cervical samples were available for a total of 14 (36.8%) patients, of which 13 (92.8%) were positive for epithelial cell abnormality. On univariate analysis, three cytomorphological variables were significant predictors of uterine CCC: presence of dense cytoplasm (OR = 88; V = 0.72), deep nuclear membrane irregularities (OR = 17.5; V = 0.55), and coarse chromatin (OR = 21.3; V = 0.46). Dense cytoplasm had the highest positive predictive value (92%) and high specificity (97.8%), whereas coarse chromatin had the highest sensitivity (92.3%) and negative predictive value (96.7%). CONCLUSIONS The presence of dense cytoplasm and deep nuclear membrane irregularities in the tumour cells were strong predictors, and coarse chromatin a moderate predictor, of uterine CCC compared to its close cytological mimics.

Abstract
Objective: To evaluate the risk of histological high-grade cervical lesions defined as cervical intraepithelial neoplasia grade 2 or worse (CIN2+) in women with human immunodeficiency virus (HIV) infection who had low-grade squamous intraepithelial lesions (LSIL) on cervical cytological screening compared with HIV-uninfected women who had similar cytology. Methods: 127 HIV-positive women aged 18–65 years with LSIL cytology undergoing colposcopic examination between January 2008 and December 2019 at Chiang Mai University Hospital were reviewed. By matching 1:1 ratio for age (±5 years) and examination time period (±12 months), 127 HIV-negative women with LSIL cytology in the same period were recruited as controlled subjects for comparison. The patients’ characteristics, HIV status, CD4 counts, antiretroviral therapy, and histopathology on cervical biopsy were analyzed. Results: HIV-infected women significantly had early sexual debut (age < 20 years) and more sexual partners (≥2) than HIV-uninfected women. The risk of underlying CIN2+ in HIV-infected women was significantly higher than that in HIV-negative women (20.5% vs. 9.4%, p = 0.021) with an odds ratio (OR) of 2.47 and 95% confidence interval (CI) = 1.18–5.14. After adjustment, the risk of underlying CIN2+ in HIV-infected women remained significantly higher than that in HIV-uninfected women (adjusted OR = 2.55, 95% CI = 1.11–5.82, p = 0.027). Conclusion: Among women with LSIL on cervical cytology, the risk of underlying CIN2+ in HIV-infected women was approximately 2.5 times higher than those without HIV infection. Colposcopy is indicated particularly in the case of women with a long duration of HIV infection.

Abstract
Objective This project aims to use our robust women's health patient data to analyze the correlation between cytology and high-risk human papillomavirus (Hr-HPV) testing, study the performance of Hr-HPV testing for detecting cytology lesions, and examine epidemiologic measures of human papillomavirus (HPV) infections in the women's veteran population. Methods We collected patient data from 2014 to 2020 from our computerized patient record system. We performed HPV assays using the cobas® 4800 system (Roche Diagnostics, Basel, Switzerland). The cobas HPV assay detects HPV 16, HPV 18, and 12 other HPV types (31, 33, 35, 39, 45, 51, 56, 58, 59, 66, and 68). We organized cytology results and Hr-HPV assays with Microsoft Access and Microsoft Excel (Microsoft Corporation, Washington, USA) for analysis. Results A total of 9437 cervical specimens were co-tested. High-grade cytology lesions - high-grade intraepithelial lesion (HSIL) or higher and atypical squamous cells, cannot exclude HSIL (ASC-H) - were overwhelmingly positive for Hr-HPV (94.1% and 87.2%, respectively). Low-grade cytology lesions - low-grade squamous intraepithelial lesion ((LSIL) and atypical squamous cells of undetermined significance (ASC-US) - were positive for Hr-HPV in lower percentages (72.6% and 54.9%, respectively). Hr-HPV testing had a sensitivity of 91.3%, a specificity of 93.1%, a positive predictive value of 16.4%, and a negative predictive value of 99.8% for detecting high-grade cytology lesions. Hr-HPV testing had a lower performance for detecting low-grade cytology lesions. Ten cases had high-grade cytology and negative Hr-HPV test. Out of 10 such patients, nine showed no dysplasia (six) or low-grade dysplasia (three) on subsequent biopsy. Overall, 14.4% of tests were positive for Hr-HPV. The highest positive Hr-HPV test rates were in the third and eighth decades of life, 25.1% and 22.0%, respectively. However, the eighth decade consisted of a small sample of only 50 women. In women over 30 years of age with Hr-HPV infections, HPV types 16 and 18 were present in 11.7% and 6.4% of tests, respectively. Other HPV types were present in 82.3% of tests. Conclusions Hr-HPV testing has a high performance in detecting high-grade cytology lesions and a lower performance for detecting low-grade cytology lesions. However, studies show that LSIL rarely progresses to cervical intraepithelial neoplasia grade 3 or higher (CIN3+), suggesting minimal to no impact on cervical cancer screening. We believe our findings are in accordance with recent studies and affirm the guidelines that recommend primary Hr-HPV testing as the preferred screening method. The percentage of positive Hr-HPV tests and rates for age and HPV types 16 and 18 in our women's veteran population suggest similar HPV prevalence to that of the general US population.

Abstract
Introduction Cervical cytology is a well‐stablished cervical cancer screening method. However, due to the anatomical continuity of the genital tract, it can also detect signs of endometrial disease. Our aim was to estimate the sensitivity of cervical cytology in endometrial cancer detection and prognosis in a large population over a 30‐year period in a large academic tertiary hospital in Spain. Methodology We performed a search for women diagnosed with endometrial cancer from 1990 to 2020, who were surgically treated and had a previous cervical cytology result. Information Technologies Department databases from Bellvitge University Hospital and the Screenwide case–control study's database were used. Cervical cytology results were classified as abnormal when squamous lesions, glandular atypia or malignant cells were identified. Results Overall, we evaluated 371 women with endometrial cancer and a documented cervical cytology performed within 3 years previous to surgical treatment. Overall, the sensitivity of cervical cytology for endometrial cancer detection was 25.6%. Several clinico‐pathological characteristics, such as non‐endometrioid histology and a higher stage, were correlated with higher sensitivity. Discussion We observed a low sensitivity of cervical cytology to effectively diagnose endometrial cancer. However, recent technological advances using genomics and epigenomics may offer a promising perspective to detect endometrial cancer with high sensitivity in these cervical specimens.

Abstract
The baseline data from the private-based opportunistic cervical cancer screening with HRHPV14, liquid-based cytology (LBC) and p16/Ki67 testing, and its quality assessment/quality control (QA/QC) tools are lacking. The age-stratified analysis of 30,066 screening tests results in a Polish population, including the investigation of HRHPV14 status, LBC, and p16/Ki67 dual-staining reporting rates, along with immediate histopathologic correlations, was conducted. For cytopathologic QA/QC, the College of American Pathologists (CAP) benchmarks and enhanced safety protocol were used. The NILM/ASC-US/LSIL/ASC-H/HSIL/AGC reporting rates were 93.9/3.4/2.0/0.22/0.24/0.11, respectively, with correlating HRHPV14-positive rates of 8.4/48.9/77.2/84.6/90.7/26.7. The reporting rates for HSIL (CIN2+) in HRHPV-positive women with NILM/ASC-US/LSIL/ASC-H/HSIL/AGC referred for a colposcopy with biopsy were 19.1/25.8/22.5/12.4/19.1/1.1% of the total HSIL (CIN2+). In total, of the 1130 p16/Ki67 tests, 30% were positive. In NILM HRHPV14-positive women with available histology result, HSIL(CIN2+) was detected in 28.3% of cases. In the first such large-scale Polish study presenting HRHPV14, informed LBC and HSIL (CIN2+) results, the reporting rates were highly consistent with data from American and other CAP-certified laboratories, confirming the possibility of using the 2019 ASCCP risk-based guidelines as one of the screening strategies outside of the US, in conditions of proper QA/QC. The private-based screening model can be effective in cervical cancer prevention, particularly in countries with low population coverage of public funds-based systems.

Abstract
Purpose The status of human papillomavirus (HPV) infection in pregnant and non-pregnant women in China remains unclear. This study aimed to compare the prevalence and genotype distributions of HPV between pregnant and non-pregnant women in China. Patients and Methods A case-control study was conducted of pregnant women during the second trimester and age-matched non-pregnant women attending the Fujian Maternity and Child Health Hospital between January 1, 2017 and December 31, 2018. Participants underwent cervical cytology testing and HPV genotyping. The genotyping test was able to identify 14 high-risk HPV (HR-HPV), four possible HR-HPV, and five low-risk HPV (LR-HPV) types. Further colposcopy and a cervical biopsy were performed if indicated. The primary outcomes were HPV prevalence and genotype distribution. Results In total, 1077 pregnant and 1077 non-pregnant women were enrolled. Compared with non-pregnant women, pregnant women had a higher prevalence of HPV (24.2% vs 14.8%), HR-HPV (20.2% vs 11.7%), and LR-HPV (8% vs 4.5%) infection. In pregnant women, the most prevalent HPV genotypes were HPV-52 (6.0%), -16 (3.5%), -58 (2.6%), -53 (2.5%), and -51 (2.5%), while in non-pregnant women the most prevalent genotypes were HPV-52 (3.6%), -81 (1.9%), -51 (1.8%), -68 (1.4%), and -16 (1.3%). In women aged ≥35 years, HR-HPV (P=0.002) and LR-HPV (P=0.001) prevalence were significantly higher in pregnant women. However, in women aged <35 years, only HR-HPV prevalence was higher in pregnant women. Pregnant and non-pregnant women with HPV-16 and HPV-58 infection had a high prevalence of high-grade squamous intra-epithelial lesions (HSIL) (HPV-16: P<0.001 and P=0.005, HPV-58: P=0.043 and P=0.005); but with other HR-HPV genotypes, only non-pregnant women had an increased HSIL prevalence. Conclusion In China, the HPV prevalence is higher in pregnant women than that in non-pregnant women and is also age- and genotype-dependent. HPV-infected pregnant women aged ≥35 years and those with HPV-16 should be closely monitored to enable rapid clinical intervention.

Abstract
Small cell neuroendocrine carcinoma (SCNEC) of the cervix is a rare, highly aggressive tumour with poor prognosis and high propensity for distant metastases. The cytological features of SCNEC have rarely been described in cervical samples, and to the best of our knowledge, there are no previous reports using SurePath™ liquid-based cytology. In the present report we present the cytomorphological features of histopathologically confirmed cases of cervical SCNEC in SurePath preparations. On cytological examination, all three cases demonstrated variable numbers of tumour cells, ranging from a few dispersed cells and tiny micro-biopsies to large aggregates of small tumour cells with a high nucleus-to-cytoplasmic ratio, stippled chromatin, inconspicuous nucleoli, and scant cytoplasm. Immunocytochemistry for CD56 on the cervical preparation confirmed the diagnosis in one case. The presence of small tumour cells with characteristic stippled/salt-and-pepper type nuclear chromatin were the most consistent cytological features in these cases. Knowledge of these characteristic cytological features can help in suggesting a diagnosis of SCNEC in cervical samples which can then be confirmed by immunocytochemistry.

Abstract
OBJECTIVE The aim of this study was to evaluate the prevalence of abnormal anal cytology in women presenting with abnormal cervical cytology (intraepithelial lesion or cervical cancer) at the largest tertiary university hospital in Thailand. METHODS A cross-sectional prospective study design was used. Anal cytology was performed on 145 women with abnormal cervical cytology between June 2014-Octoble 2014. If abnormal anal cytology was detected, anoscopy was performed with biopsy in any suspicious area of precancerous change. RESULTS Prevalence of abnormal anal cytology was 5.5% (8 patients). Of 8 patients, six patients presented with low-grade squamous intraepithelial lesion, one patient with high-grade squamous intraepithelial lesion, and one with atypical squamous cell cannot exclude high-grade squamous intraepithelial lesion. Abnormal anoscopic impression was found in 3 cases, as follow: The first case showed faint acetowhite lesion and anoscopic impression was low grade squamous intraepithelial lesion; the second case was reported as human papillomavirus (HPV) change by anoscopic impression; and the third case showed dense acetowhite lesion with multiple punctation and pathologic examination showed anal intraepithelial neoplasm III (AIN3). The last patient underwent wide local excision of AIN3 with split-thickness skin graft reconstruction. Final pathology confirmed AIN3 with free resection margin. CONCLUSION Prevalence of abnormal anal cytology was 5.5% in patients with abnormal cervical cytology. The prevalence might be support anal cytology screening in this group of patients.

Abstract
OBJECTIVE Cervical cancer screening by primary human papilloma virus detection and cytology is fraught with low specificity and variable sensitivity, respectively. Cytology-histology correlation remains modest. Biomarkers associated with early genetic events in cervical squamous carcinogenesis and detectable in cytology material are likely to be relevant. Human telomerase RNA component (hTERC) gene overexpression and aneuploidy are promising candidates in view of their reported early and consistent association with cervical squamous oncogenesis. METHODS We analysed hTERC gene expression and chromosome 7 ploidy by fluorescent in-situ hybridisation (FISH) in 50 women with cytological precursor squamous intraepithelial lesions and available histology outcomes. Results were expressed as percentages of cells showing ≥3 signals, mean signals/nucleus, and maximum amplitude across various cytology and histology categories. Proportions of positive cases were calculated from threshold values derived from 6 controls. Distribution of above indices with respect to ≥cervical intraepithelial neoplasia 2 (CIN2) was explored. RESULTS For both genetic aberrations, there was significant positive correlation (for all indices) between the proportion of positive cases and worsening cytological and histological outcomes (P < .05), with significant intergroup differences (P < .05). High-grade lesions (≥CIN2) had significantly higher results compared to <CIN2 lesions (P ≤ .001). In five discordant cases with ≥CIN2 under- or overdiagnosed on cytology, FISH supported the histological diagnosis. CONCLUSIONS HTERC gene amplification and chromosome 7 ploidy showed positive association with cervical squamous carcinogenesis and could be relevant in settings of discrepant cytology-histology correlation.

Abstract
BACKGROUND Cervical cytology screening is usually laborious with a heavy workload and poor diagnostic consistency. The authors have developed an artificial intelligence (AI) microscope that can provide onsite diagnostic assistance for cervical cytology screening in real time. METHODS A total of 2167 cervical cytology slides were selected from a cohort of 10,601 cases from Shenzhen Maternity and Child Healthcare Hospital, and the training data set consisted of 42,073 abnormal cervical epithelial cells. The recognition results of an AI technique were presented in a microscope eyepiece by an augmented reality technique. Potentially abnormal cells were highlighted with binary classification results in a 10× field of view (FOV) and with multiclassification results according to the Bethesda system in 20× and 40× FOVs. In addition, 486 slides were selected for the reader study to evaluate the performance of the AI microscope. RESULTS In the reader study, which compared manual reading with AI assistance, the sensitivities for the detection of low-grade squamous intraepithelial lesions and high-grade squamous intraepithelial lesions were significantly improved from 0.837 to 0.923 (P < .001) and from 0.830 to 0.917 (P < .01), respectively; the κ score for atypical squamous cells of undetermined significance (ASCUS) was improved from 0.581 to 0.637; the averaged pairwise κ of consistency for multiclassification was improved from 0.649 to 0.706; the averaged pairwise κ of consistency for binary classification was improved from 0.720 to 0.798; and the averaged pairwise κ of ASCUS was improved from 0.557 to 0.639. CONCLUSIONS The results of this study show that an AI microscope can provide real-time assistance for cervical cytology screening and improve the efficiency and accuracy of cervical cytology diagnosis.

Abstract
The Polish Society of Colposcopy and Cervical Pathophysiology (PTKiPSM) together with the Polish Society of Gynecologists and Obstetricians (PTGiP) issued a final summary of interim guidelines for secondary cervical cancer prevention during the SARS-CoV-2 pandemic based on the analysis of the latest directional publications and the authors' own experiences. The aim of the summary is to facilitate the implementation of the most effective possible screening of cervical precancerous lesions and cervical cancer due to temporary significant limitation of screening as a consequence of the ongoing epidemiological threat. These final guidelines are taking into account the 2020 call of the World Health Organization (WHO) for global epidemiological elimination of cervical cancer. The guidelines supplement the interim guidelines of PTKiPSM and PTGiP announced in March 2020 on the possible deferral of diagnostic and therapeutic procedures in patients with abnormal screening tests results in secondary prevention of cervical cancer in current pandemic.

Abstract
BACKGROUND Human papillomavirus (HPV) genotype testing has limited utility to identify human immunodeficiency virus-infected (HIV+) women's risk for developing cervical cancer (CC) due to high positivity rate of high-risk (HR) HPVs. We investigated the accuracy of HPV testing in isolation/in combination with CD4 and HIV viral load (VL) to identify HIV+ women at risk for developing CC. METHODS Study consisted of 344 HIV+ women on combination antiretroviral therapy (cART), tested for cervical cytology/HPV using the Cobas test and had data on absolute CD4 count and VL measurements. We calculated the positive predictive value (PPV) and negative predictive value (NPV) of HPV testing, pre-, post-cART, and current CD4 and VL in isolation and in combinations to identify those with or free of higher than atypical squamous cells of unknown significance (ASCUS+) or low-grade intraepithelial lesions (LSIL+). RESULTS HPV test in combination with pre-/post-cART or current CD4 counts and VL had higher PPVs compared to HPV test alone for identifying ASCUS+ or LSIL+. PPV of HPV-CD4 combinations yielded higher PPVs compared to HPV-VL combinations. The NPVs with pre-, post-cART, or current CD4 count and VL in isolation or in combinations were comparable to that of HPV test alone. CONCLUSIONS Our results provide a more accurate tool for managing HIV+ women by combining Cobas HPV with CD4 and VL, especially those who had an undesirable pre-cART CD4 and VL status. Our results also indicate the usefulness of CD4 and VL measurements to identify those at lower risk in the absence of HPV testing.

Abstract
INTRODUCTION Human papillomavirus (HPV) is the causative agent of precancerous lesions and cervical cancer, cervical cancer being the leading cause of deaths in Tanzanian women. Early detection and treatment of precancerous lesions are important in the prevention of cervical cancer cases. MATERIAL AND METHODS We conducted a cross-sectional study among 3390 Tanzanian women aged 25-60 years. Information on lifestyle habits was collected, and women underwent gynecological examination with collection of cervical cells for conventional cytological and HPV testing. Blood samples were tested for HIV. The association between cervical high-grade cytology (HGC) and potential risk factors was examined using multivariable logistic regression adjusting for age and high-risk HPV (HR-HPV). RESULTS The prevalence of HGC was 3.6% and of low-grade cytology was 8.3%. In women who were both HR-HPV-positive and HIV-positive, the prevalence of HGC was 28.3%. It increased by age and was 47% among women aged 50-60 years. Women, who had their sexual debut at age 9-15 years and 16-18 years, respectively, had 2.5 and 2.4 times increased odds of HGC compared with women whose sexual debut was at age 21 years and older. HIV-positive women had increased odds of HGC in comparison with HIV-negative women after adjustment for age (odds ratio [OR] 2.95, 95% CI 1.92-4.54). HR-HPV-positive women had nearly 100-fold increased odds of HGC compared with HR-HPV-negative women (OR 96.6, 95% CI 48.0-194), and this estimate was higher among HIV-positive women (OR 152.2, 95% CI 36.1-642.0). CONCLUSIONS Increasing age, early age at first intercourse, HR-HPV, and HIV infections were associated with a substantially increased risk of HGC.

Abstract
Background and objective: Women with human immunodeficiency virus (HIV) infection have an increased risk of HPV infection, cervical neoplasia. This study was undertaken to compare the risk of having high-grade cervical lesions defined as cervical intraepithelial neoplasia grade 2 or worse (CIN2+) in HIV-infected versus HIV-uninfected women who had atypical squamous cells of undetermined significance (ASC-US) on cervical cytology. Methods: Fifty-seven HIV-positive women aged 25-65 years with ASC-US cytology undergoing colposcopic examination between January 2008 and December 2020 at Chiang Mai University Hospital were reviewed. By matching 1:5 ratio, 285 HIV-negative women with ASC-US cytology in the same period were recruited as controlled subjects for comparison. The patient characteristics, HIV status, CD4 cell count within 6 months of colposcopy, antiretroviral therapy, parity, contraception, smoking history, number of sexual partners, and histopathology on cervical biopsy were analyzed. Results: Mean age ± SD of the HIV-positive and HIV-negative groups was 44.28 ± 8.53 years and 44.28 ± 9.68 years, respectively. HIV-positive women were significantly less likely to use contraceptive methods (36.8 % versus 48.8 % in HIV-negative women; P = 0.002). HIV-infected women significantly had more sexual partners than HIV-uninfected women. Both groups had similar risk for CIN 2+ (5.3 % in HIV-positive women compared with 4.9 % in HIV-negative women; odds ratio [OR] = 1.08, 95% confidence interval [CI] = 0.30 –3.87). After adjustment for no contraception use and number of sexual partners, the risk of CIN2+ in HIV-infected women remained unchanged; adjusted OR= 1.15, 95% CI = 0.27-4.92, P= 0.846). Conclusion: The risk of underlying high-grade cervical lesions in women with ASC-US on cervical cytology was approximately 5 %, regardless of HIV status.

Abstract
OBJECTIVE Cervical cytology and Human papillomavirus (HPV) testing are effective screening techniques but both have limitations. A few recent studies in the literature have highlighted the role of co-expression of p16INK4a and Ki-67 for cervical cancer screening. The present study was undertaken to evaluate the diagnostic performance of the CINtec® PLUS kit (dual immunostaining for p16 and Ki-67) in SurePathTM liquid-based (LBC) cervico-vaginal samples. MATERIALS AND METHODS This was a prospective study performed on 52 cervico-vaginal SurePath™ LBC samples reported as having squamous epithelial cell abnormality (ECA). All the samples were stained using CINtec® PLUS kits. Additionally, HPV-DNA testing was also done and the results were compared. RESULTS The age range was 34-74 years. ECA included 18 (34.6%) cases of ASC-US, 9 (17.3%) cases of low-grade squamous intraepithelial lesion (LSIL), 11 (21.2%) cases of high-grade squamous intraepithelial lesion (HSIL), and 14 (26.9%) cases of squamous cell carcinoma (SCC). Cervical biopsies were available in 19 (36.5%) cases. A total of 34/52 (65.4%) cases were positive for HPV-DNA (5/18-ASC-US; 6/9-LSIL; 10/11-HSIL; 13/14-SCC). The CINtec® PLUS test was positive in 41/52 (78.8%) cases (11/18-ASC-US; 6/9-LSIL; 11/11-HSIL; 13/14-SCC). On comparing CINtec® PLUS positivity (78.8%) with HPV positivity (65.4%), dual positivity was seen in 3/18 cases of ASC-US, 6/9 cases of LSIL, 10/11 cases of HSIL, and 12/14 cases of SCC. One case each of HSIL and SCC was negative on the HPV test and was positive on CINtec® PLUS. CONCLUSIONS CINtec® PLUS test helps to improve the detection of pre-cancerous cervical lesions as compared to cervical cytology or HPV testing alone and hence can serve as a potentially useful diagnostic and triage tool, especially for indeterminate cases.

Abstract
OBJECTIVE To systematically review the role of aneuploidy detection alone or in combination with other methods in cervical cancer screening and to evaluate the value of aneuploidy to predict the behavior of premalignant cervical lesions. METHOD We conducted a systematic review based on an electronic search for articles published between 2001 and 2020 across databases including MEDLINE/PubMed, Scopus, and Web of Science. Studies were subjected to data extraction, risk of bias, and narrative synthesis. RESULTS A total of 15 articles were included in the review. Eight out of 15 studies (53.3%) were judged to be at a high or unclear risk of bias. From the 15 included studies, the index test to detect aneuploidy was DNA image cytometry (DNA-ICM) in 12 studies and DNA flow cytometry (DNA-FCM) in three studies. Nine studies also evaluated the performance of cytology and/or human papillomavirus (HPV) tests. For DNA-ICM, sensitivity to detect cervical intraepithelial neoplasia or worse (CIN2+) varied between 59.0% and 95.9% and specificity varied between 54.1% and 100%. For DNA-FCM, sensitivity varied between 27.3% to 96.8% and specificity was 100%. For cytological evaluation, sensitivity varied between 25.0% and 70.4% and specificity varied between 70.6% and 99.9%. For HPV detection, sensitivity varied between 39.4% and 100% and specificity varied between 23.3% and 84.3%. CONCLUSION DNA ploidy along with atypical cells findings in cytology and/or HPV detection revealed great value to detect CIN2+ lesions and to predict which lesions are more likely to progress to cervical cancer.

Abstract
BACKGROUND Atypical glandular cells (AGC) as a diagnostic category in cervicovaginal cytology remains as a challenge to cytopathologists. AIMS The aim of the present study is to identify the cytological features helpful in categorizing AGC as reactive or neoplastic upon correlation with histology. MATERIALS AND METHODS The study was a retrospective review of cervical smears, with histopathological follow up, reported as glandular lesions for a period of 9 years. The architectural and nuclear features studied were adapted from The Bethesda System (TBS) to stratify the lesions as AGC, AGC-FN (atypical glandular cells favour neoplasia) and adenocarcinoma. The cytological categories were correlated with histology. RESULTS A total of 89 cases of which 67 (AGC NOS = 34, AGC FN = 19, adenocarcinoma = 14) with histology were reviewed. Neoplastic lesions were encountered in 14 cases (34.6%). Of the cases diagnosed as AGC-NOS, AGC-FN and adenocarcinoma, 26.5%, 68.4% and 100% respectively were neoplastic on histopathology. Squamous lesions accounted for 14.9% of all the glandular lesions. Rosette or acinar formation and loss of polarity frequently observed in neoplastic lesions as compared to reactive changes (p = 0.0004, p = 0.001). Of the nuclear features, nuclear hyperchromasia or coarse clumping of chromatin along with nuclear membrane irregularity and nuclear pleomorphism was frequently associated with neoplastic lesions as compared to reactive conditions (p = 0.007, p = 0.001, p = 0.0002). CONCLUSION A diagnosis of AGC at cytology harbors significant number of malignant lesions when confirmed on biopsy. Architectural features complemented with nuclear characteristics helps in differentiating between reactive and neoplastic conditions. Hence stratifying glandular lesions at cytology according to TBS helps in the management.

Abstract
INTRODUCTION Gastric-type endocervical adenocarcinoma (GAS) is an uncommon type of endocervical adenocarcinoma that is not associated with human papillomavirus infection. This diagnosis is relatively rare and may portend a worse prognosis than usual-type endocervical adenocarcinoma. Subtle morphological features make it an under-recognised diagnostic challenge. Study of the cytological features of individual cases is valuable in order to increase awareness of this entity. METHODS The pathology database of our institution was searched for the diagnosis of GAS and all cytological and surgical specimens for each patient were reviewed. The original cytological interpretation was compared to a retrospective central review interpretation. Clinical history and follow-up results were obtained from the electronic medical record. RESULTS Four cases of GAS were identified. The findings on initial cervical cytology varied, with GAS found in both patients with negative cervical cytology and those with atypical glandular cells. Cytological findings included endocervical cells arranged in three-dimensional clusters and honeycomb sheets with abundant vacuolar cytoplasm, and in two patients, moderate nuclear atypia with irregular nuclear membranes, coarse chromatin, hyperchromatic nuclei, and prominent nucleoli. In one patient, GAS was incidentally discovered via thorough sampling of a cystic lesion in the superior portion of the endocervical canal. CONCLUSIONS GAS is an aggressive human papillomavirus-independent type of endocervical adenocarcinoma with subtle morphological features and, as our study shows, varying clinical presentation. Given the aggressive nature of GAS and the difficulties in initial diagnosis, increased awareness of this entity among pathologists is crucial.

Abstract
BACKGROUND Human papillomavirus (HPV) infection is the main pathogen of precancerous transformation and finally progress to cervical cancer. It associated with cervical squamous and glandular lesions. However, the genotype distribution of HPV and the relationship between HPV infection and cervical disease are still remind unclear. MATERIAL AND METHODS A total of 7391 abnormal cervical cytology cases with detailed histological reports and HPV genotypes were collected. The prevalence of HPV infection in squamous epithelial lesions and glandular epithelial lesions were statistically analyzed. RESULT Around 6958 cytological squamous epithelial lesions and 433 glandular epithelial lesions were enrolled. 79.72% of cytological squamous epithelial lesions and 26.56% of glandular epithelial lesions were HPV infected. The HPV infection rates in squamous cell carcinoma, cervical adenocarcinoma and endometrial adenocarcinoma were 66.67%, 54.17% and 19.72%, respectively. HVP16, 18 and 58 are the most common types in squamous and glandular epithelial lesions. Among the squamous epithelial lesions, women less than 25 years old had the highest HPV infection rate, and majority of multiple infections was found in women >55 years old. The total infection rate of HPV in glandular epithelial lesions was the highest in the 35 to 45 group. Multiple infections peaked in women around 55 years old. CONCLUSION The prevalence of HPV infection is divergent in different types of cervical cancer. The HPV infections in cervical squamous epithelial lesions tended to be younger. HPV detection is one of the necessary tests for cervical disease screening and should be individualized in an age manner.

Abstract
Objectives: To compare the effectiveness between Qi brush and Cervex-Brush® Combi for the diagnosis of cervical lesions. Methods: After we registered a random-control clinical trial on the Chinese Clinical Trial Registry (No. XJTU1AF2017LSK-25), cervical cell samples were successively collected with both Qi brush and Cervex-Brush® Combi before undergoing colposcope. Colposcopy with biopsy was performed later. Histological diagnosis was regarded as the gold standard in this study. The following indices of the two brushes were compared: sampling degree of satisfaction and presence rate of metaplastic cells, together with sensitivity (Se), specificity (Sp), false positives (FP), false negatives (FN), positive predictive value (PPV), and negative predictive value (NPV). The kappa value was used to measure the inter-rater agreement of the Qi brush and Cervex-Brush® Combi in diagnosing cervical lesions. Results: In total, 74 patients were enrolled in this study. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of the Qi brush were 57.14, 86.84, 76.19, and 73.33%, respectively. For the Cervex-Brush® Combi, they were 26.92, 88.89, 63.63, and 62.75%, respectively. In addition, the Qi brush had a higher satisfied sampling rate (89.19%) than the Cervex-Brush® Combi (83.78%), and the P-value was 0.336 using Chi-square test. The kappa value was 0.444, which indicated a medium agreement between these two brushes, and the sensitivity of the Qi brush was higher than that of the Cervex-Brush® Combi, with significant statistical difference (P = 0.039<0.05). Conclusions: The Qi brush was more effective than the Cervex-Brush® Combi for sampling and also had a slightly higher accuracy in diagnosing in cytology. In terms of social and economic benefits, the Qi brush may be a better cervical cytology collector.

Abstract
BACKGROUND Women with human immunodeficiency virus have higher rates of abnormal cervical and vaginal cytology and, subsequently, of cervical and vaginal cancers. Although professional bodies currently advocate for indefinite cytology screening for women living with human immunodeficiency virus, these recommendations are based on expert opinion, not evidence-based. In the general population, women who have never had an abnormal cytology result can cease screening at age 65 years. This is due to the relatively low incidence of dysplasia in this group and the risk of false-positive results as women age, invasive follow-up testing, and destructive treatments of lesions that are unlikely to progress to cancer. What is unclear, however, is how human immunodeficiency virus-infected women over age 65 years who have no history of abnormal cytology should be screened to maximize benefit while reducing harms of overscreening. This is a crucial question, as women over age 65 years who are living with human immunodeficiency virus comprise a rapidly growing population. OBJECTIVE To describe the incidence of abnormal cervical and vaginal cytology results in women over the age of 65 years living with human immunodeficiency virus, with the goal of providing evidence for screening recommendations. MATERIALS AND METHODS A retrospective chart review was performed, identifying 69 women who received gynecologic follow-up in a county hospital system in Houston, Texas, between 2000 and 2018 and who met study criteria. Incidence of abnormal cytology after age 65 was determined by analyzing all available cytology results after age 65. Demographic and clinical risk factors, including human immunodeficiency virus-specific clinical risk factors, were analyzed. Matched cervical and vaginal pathology results, if conducted, were also evaluated. Statistical analyses were conducted using Stata 15, including χ2 tests and Wilcoxon rank-sum tests for categorical and continuous variables, respectively. Estimates of the cumulative probability of developing an abnormal cytology result was calculated using the Kaplan-Meier method. RESULTS Among 69 women with no history of abnormal cervical cytology, 12 (17%) went on to develop abnormal cytology results, including 3 (4%) showing high-grade squamous intraepithelial lesions. The incidence rate was 3.5 cases per 100 woman-years (95% confidence interval, 1.58, 7.81). No demographic or gynecologic characteristics were associated with abnormal cytology. A CD4 count of <200 at the time of human immunodeficiency virus diagnosis or at the time of cytology was associated with an abnormal Papanicolaou test result (P < .0001, P = .031). Of women with pathology results in the county hospital system (n = 8), 4 (50%) had cervical intraepithelial neoplasia 2+ or vaginal intraepithelial neoplasia 2+. No women developed invasive cancer. However, 50% of women who had an abnormal Papanicolaou test result in the study period were lost to follow-up; outcomes for these patients are unknown. CONCLUSION Given the relatively high proportion (4%) of women with high-grade squamous intraepithelial lesions/cervical intraepithelial neoplasia 2+/vaginal intraepithelial neoplasia 2+ during the study period, we agree with current screening recommendations for continued routine Papanicolaou testing after the age of 65 years in women with human immunodeficiency virus. More evidence from larger studies is needed to solidify evidence-based screening recommendations in this unique and growing population.

Abstract
OBJECTIVE The objective of the present study was to assess the prevalence and type-specific distribution of cervical high-risk (HR) human papillomavirus (HPV) among women with normal and abnormal cytology, and to describe risk factors for HR HPV among HIV-positive and HIV-negative women in Tanzania. METHODOLOGY A cross-sectional study was conducted in existing cervical cancer screening clinics in Kilimanjaro and Dar es Salaam. Cervical specimens were obtained from women aged 25-60 years. Samples were shipped to Denmark for cytological examination, and to Germany for HR HPV testing (using Hybrid Capture 2) and genotyping (using LiPaExtra). Risk factors associated with HPV were assessed by multivariable logistic regression analysis. RESULT Altogether, 4080 women were recruited with 3416 women contributing data for the present paper, including 609 HIV-positive women and 2807 HIV-negative women. The overall HR HPV prevalence was 18.9%, whereas the HR HPV prevalence in women with high-grade squamous intraepithelial lesions (HSILs) was 92.7%. Among HPV-positive women with HSIL, HPV16 (32.5%) and HPV58 (19.3%) were the the most common types followed by HPV18 (16.7%) and HPV52 (16.7%). Factors associated with HR HPV included younger age, increasing number of partners and early age at first intercourse. Similar risk factors were found among HIV-positive and HIV-negative women. In addition, among HIV-positive women, those with CD4 counts <200 cells/mm3 had an increased risk of HR HPV (OR 2.2; 95% CI 1.2 to 4.8) compared with individuals with CD4 count ≥500 cells/mm3. CONCLUSION Given the HPV distribution among Tanzanian women, the current HPV vaccination in Tanzania using quadrivalent vaccine may be considered replaced by the nonavalent vaccine in the future. In addition, appropriate antiretroviral treatment management including monitoring of viremia may decrease the burden of HR HPV in HIV-positive women.
