OBJECTIVES
To perform a systematic review of gastric-type adenocarcinoma of the cervix and lobular endocervical glandular hyperplasia (a possible precursor lesion) in Peutz-Jeghers syndrome, and to analyze data from the literature, along with our institutional experience, to determine recommendations for screening and detection.
METHODS
A comprehensive literature searc and retrospective search of pathology records at our institutio were conducted. Articles were screened by two independent reviewers. Case reports/series on lobular endocervical glandular hyperplasia/gastric-type adenocarcinoma of the cervix in Peutz-Jeghers syndrome were included. Demographic, clinical, and radiologic information was collected.
RESULTS
A total of 1564 publications were reviewed; 38 met the inclusion criteria. Forty-nine were included in the analysis (43 from the literature, 6 from our institution). Forty-three reported on gastric-type adenocarcinoma alone, 4 on lobular endocervical glandular hyperplasia alone, and 2 on concurrent lobular endocervical glandular hyperplasia/gastric-type adenocarcinoma. Median age at diagnosis was 17 (range, 4-52) for patients with lobular endocervical glandular hyperplasia alone and 35 (range, 15-72) for those with gastric-type adenocarcinoma. The most common presenting symptoms were abdominal/pelvic pain and vaginal bleeding/discharge. Imaging was reported for 27 patients; 24 (89%) had abnormal cervical features. Papanicolaou (Pap) smear prior to diagnosis was reported for 12 patients; 6 (50%) had normal cytology, 4 (33%) atypical glandular cells, and 2 (17%) atypical cells not otherwise specified. Patients with gastric-type adenocarcinoma (n=45) were treated with surgery alone (n=16), surgery/chemotherapy/radiation (n=11), surgery/chemotherapy (n=9), surgery/radiation (n=5), or radiation/chemotherapy (n=4). Twelve (27%) of 45 patients recurred; median progression-free survival was 10 months (range, 1-148). Twenty patients (44%) died; median overall survival was 26 months (range, 2-156). Thirteen patients (27%) were alive with no evidence of disease.
CONCLUSIONS
Gastric-type adenocarcinoma in Peutz-Jeghers syndrome is associated with poor outcomes and short progression-free and overall survival. Screening recommendations, including pathognomonic symptom review and physical examination, with a low threshold for imaging and biopsy, may detect precursor lesions and early-stage gastric-type adenocarcinoma, leading to better outcomes in this high-risk population.

Review
BACKGROUND
To investigate the role of self-sampling for human papillomavirus (HPV) testing as an alternative to cervical cancer screening by clinicians (i.e., Papanicolaou [Pap] test).
METHODS
A systematic search of MEDLINE, EMBASE, Cochrane Library, and other sources for evidence related to the efficacy and feasibility of HPV DNA self-collection.
RESULTS
A total of 25 studies were identified. In 22 comparisons across 19 studies, the concordance between samples collected by patients and those obtained by clinicians was reasonably high in the majority of cases. Women in many countries across wide age ranges were successful in collecting samples for HPV DNA testing. In four studies, the quality of the cytology from patient samples was as good as clinician samples, with more than 95% of samples yielding HPV DNA results. The studies that examined acceptability found that women were generally very positive about collecting their own samples, although some concerns were noted. No study evaluated the effect of HPV DNA self-sampling on screening participation rates, early detection, survival, or quality of life.
CONCLUSIONS
Self-sampling for HPV DNA testing is a viable screening option, but there is insufficient evidence to conclude that self-sampling for HPV DNA testing is an alternative to the Pap test. Although HPV DNA testing using self-collected samples holds promise for use in under-resourced areas or for women who are reluctant to participate in Pap testing programs, the evidence supporting it is limited. Further definitive research is needed to provide a solid evidence base to inform the use of self-sampling for HPV DNA testing for the purpose of increasing screening rates, especially in women who are never or seldom screened.

Incarcerated women often access health care primarily through contact with correctional systems. Cervical cancer screening within the correctional system can address the preventable outcome of cervical dysplasia and cancer in this high-risk population. A search of PubMed, EMBASE, CINAHL, and ClinicalTrials.gov was conducted for articles published between January, 1966 and December, 2018. All studies on a population of jailed or incarcerated females and at least one of the following outcomes: cervical cancer or dysplasia, pap smear screening, knowledge about screening, treatment of cervical dysplasia, and compliance with follow-up were analyzed. Forty-two studies met inclusion criteria. All 21 studies with prevalence outcomes described a higher prevalence of cervical dysplasia and cancer in the women involved with corrections, compared to a variety of different sources that served as community control groups. The data on screening outcomes were inconsistent. Follow-up compliance for abnormal results was poor, with a study finding that only 21% of women were rescreened within 6 months of the recommended time period. Knowledge about cervical cancer and screening was evaluated in eight studies and was poor across all studies. Women involved in correctional systems have a higher prevalence of cervical dysplasia and cancer than women in the general population. Acceptance of screening varies, and no published interventions have been shown to improve screening within the prison system. Treatment and compliance with follow-up recommendations are extremely poor and should be a focus of future research.

Review
It has been reported that many women referred to outpatient colposcopy clinics fail to attend for their appointments. The aim of this paper is to search the literature to assess the extent of default from colposcopy and to identify interventions, suitable for implementation within primary care, to reduce the proportion of women defaulting. Searches were performed on MEDLINE, PsychLIT, Bids and Cancerlit from 1986 to September 1997 using the terms colposcopy or cervical/Pap smear in association with default, non-attendance, adherence, patient compliance, treatment refusal, patient dropouts, attendance, barriers or intervention. The inclusion criteria for primary papers were that they contained data that enables the calculation of default rates for colposcopy or the results of interventions aimed at improving the default rates. Thirteen publications describing default rates and four describing interventions were included as primary papers. Combining the data from these studies suggests default rates of 3%, 11%, and 12% for assessment/treatment visits, first review, and second review respectively. The intervention studies suggested a need to tailor the intervention to the population and the type of information to suit the individual. Varying definitions make comparison of default rates difficult, and the use of a crude non-attendance rate may result in an overestimate of default rates. The vast majority of women invited to colposcopy eventually attend. It is questionable if there is a need for interventions to increase compliance. Where necessary, greater cooperation across the primary/secondary care interface and use of the extended primary care team may be a more cost-effective means of increasing compliance.

CONTEXT
Pap smear test is one of the most important actions in preventing cervical cancer. This study aimed to perform a meta-analysis on all related literature about the effects of health belief model (HBM)-based training on Pap smear screening test performance of Iranian women.
METHODS
The search was performed in Scopus, PubMed, and Web of Science. Eligibility criteria were limited to English and Persian language articles with experimental or semi-experimental methods until October 2019 that evaluated the effect of HBM-based training on Iranian women's performance of Pap smear test. We excluded studies that used both cervical and breast cancer screening together.
RESULTS
Twelve studies were performed on totally 1605 participants. This meta-analysis showed that all of Health Belief Model (HBM) constructs improved significantly among HBM-based trained women, perceived susceptibility (standard mean division [SMD] =0.785; = 0.002; confidence interval [CI] = 0.005 to 1.56; Heterogeneity; = 0.013; = 97%)., perceived severity (SMD = 1.14; = 0.001; CI = 0.66-1.62; heterogeneity; < 0.001; = 92%), perceived benefits (SMD = 1.25; = 0.001; CI = 0.545-0.135 heterogeneity; = 0.003; = 97%), perceived barrier (SMD = 0.20; = 0.001; CI = 0.44-1.24; heterogeneity; < 0.001; = 92%) and perceived self-efficacy (SMD = 0.638; < 0.001; CI =1.76-0.426; heterogeneity; < 0.001; = 97%).
CONCLUSION
Cervical screening education program based on the HBM can be effective on Iranian women's performance in their perceived susceptibility, perceived severity, perceived barrier, and perceived self-efficacy about Pap smear test.

Diagnostic Performance of Bile Duct Brush Cytology with Risk of Malignancy of Standardized Categories in the Wake of World Health Organization Reporting System for Pancreaticobiliary Cytopathology: An Updated Systematic Review and Meta-Analysis.
INTRODUCTION
The WHO Reporting System for Pancreaticobiliary Cytopathology revised the Papanicolaou Society of Cytopathology guidelines in alignment with the WHO classification of digestive system tumors, 5th edition. The current systematic review and meta-analysis have been conducted to accurately assess the performance of bile duct brush cytology and report the risk of malignancy (ROM) of each standard category by following the guidelines of diagnostic test accuracy meta-analysis.
METHODS
Medline/Pubmed and Cochrane databases were searched till June 8, 2023, with a strategy that included target site (pancreaticobiliary and related terms), diagnostic method (bile duct brushing and related terms), and keywords for diagnostic performance (for Cochrane database). Inclusion criteria included studies that have assessed bile duct cytology (BDC) for pancreaticobiliary duct stricture with a sample size of over 50, provided cytological diagnoses similar to the WHO system with details to deduce true positives, true negatives, false positives, and false negatives through subsequent final diagnoses (benign vs. malignant). The exclusion criteria were the fewer sample size, assessment through other cytological categories, limited data, and clinical setting. Two authors independently reviewed the result of the search strategy. The quality of the selected articles was assessed by the QUADAS-2 tool. Bivariate random-effects model was used to get the pooled sensitivity and specificity. Heterogeneity across studies was assessed using I-squared statistics, and potential sources were found using meta-regression. Pooled and a range of ROM in each category was analyzed.
RESULTS
Thirteen studies were included with 4,398 bile duct brushings. The pooled sensitivity is 0.437 (95% CI: 0.371-0.504), and the pooled specificity is 0.972 (95% CI: 0.943-0.987). The ROM in various categories are as follows: inadequate/nondiagnostic: 23-100% (pooled: 50.15%), benign/negative for malignancy: 22-70% (38%), atypical: 0-95% (66%), suspicious for malignancy: 74-100% (89%), malignant: 91-100% (98%).
CONCLUSION
Even with standard cytological categories, the sensitivity of BDC remains low. The review has analyzed and discussed potential causes of heterogeneity that will be helpful for future diagnostic studies.

BACKGROUND
Developed countries, such as the USA, have achieved significant decreases in cervical cancer burden since the introduction of Pap smear-based programs in the 1960s. Due to implementation barriers and limited resources, many countries in sub-Saharan Africa (SSA) have been unable to attain such reductions. The purpose of this review is to evaluate implementation strategies used to improve the uptake and sustainability of cervical cancer prevention programs in SSA.
METHODS
A reviewer (LJ) independently searched PubMed, Ovid/MEDLINE, Scopus, and Web of Science databases for relevant articles with the following search limits: English language, peer reviewed, and published between 1996 and 2017. The 4575 search results were screened for eligibility (CJ, LJ) to identify original research that empirically evaluated or tested implementation strategies to improve cervical cancer prevention in SSA. Fifty-three articles met criteria for inclusion in the final review. AA, CJ, and LJ abstracted the included articles for implementation-related content and evaluated them for risk of bias according to study design with the National Heart, Lung, and Blood Institute's (NHLBI) Quality Assessment Tools. Results were reported according to PRISMA guidelines.
RESULTS
The 53 included studies are well represented among all sub-Saharan regions: South (n = 16, 30.2%), West (n = 16, 30.2%), East (n = 14, 26.4%), and Middle (n = 7, 13.2%). There are 34 cross-sectional studies (64.2%), 10 pre-posttests (18.9%), 8 randomized control trials (15.1%), and one nonrandomized control trial (1.9%). Most studies are "fair" quality (n = 22, 41.5%). Visual inspection with acetic acid (VIA) (n = 19, 35.8%) was used as the main prevention method more frequently than HPV DNA/mRNA testing (n = 15, 28.3%), Pap smear (n = 13, 24.5%), and HPV vaccine (n = 9, 17.0%). Effectiveness of strategies to improve program implementation was measured using implementation outcomes of penetration (n = 33, 62.3%), acceptability (n = 15, 28.3%), fidelity (n = 14, 26.4%), feasibility (n = 8, 15.1%), adoption (n = 6, 11.3%), sustainability (n = 2, 3.8%), and cost (n = 1, 1.9%). Education strategies (n = 38, 71.7%) were used most often but have shown limited effectiveness.
CONCLUSION
This systematic review highlights the need to diversify strategies that are used to improve implementation for cervical cancer prevention programs. While education is important, implementation science literature reveals that education is not as effective in generating change. There is a need for additional organizational support to further incentivize and sustain improvements in implementation.

Comparative Study Review
OBJECTIVE
We compared fluid-based cytologies (FBC) with conventional Papanicolaou (Pap) tests (CT) to determine if either is superior.
STUDY DESIGN
This was a systematic review of original research reports evaluating both CT and FBC with respect to specimen adequacy, comparison with a reference standard, or both. Two reviewers independently reviewed the titles, abstracts, and full articles to determine inclusion status, with differences resolved by consensus with a third author. Risk differences (RD) between occurrence rates for FBC and CT were used for the specimen adequacy data. Sensitivity and specificity were pooled independently and weighted by the inverse of the variance using a random effects model.
DATA SOURCES
Studies published between 1985 and November 1999 were identified from MEDLINE, Best Evidence, EMBASE, Biological Abstracts/RRM, and The Cochrane Library.
OUTCOMES MEASURED
Sensitivity, specificity, area under the receiver operating characteristic curve (AuROC), and the proportion of satisfactory, unsatisfactory, and "satisfactory but limited by" test results were measured.
RESULTS
There was no significant difference in AuROC (P = .37). FBC specimens were more likely to be satisfactory (RD=0.06; 95% confidence interval [CI], 0.03-0.09) or to have absent endocervical cells (RD=0.06; 95% CI, 0.02-0.10) but had 10% fewer "satisfactory but limited by - other" reports (RD = -0.10; 95% CI, -0.14 to -0.06). There was no difference in unsatisfactory Pap test results.
CONCLUSIONS
For most women there is no reason to replace CT with FBC. For women at high risk of cervical cancer or who are screened infrequently, the possible increase in FBC sensitivity may outweigh the potential harms from additional false positives.

To systematically summarize and assess risk prediction models for occurrence of cervical cancer and to provide evidence for selecting the most reliable model for practice, and guide cervical cancer screening. Two groups of keywords related to cervical cancer and risk prediction model were searched on Chinese databases (CNKI, and Wanfang) and English databases (PubMed, Embase, and Cochrane Library). Original articles that developed or validated risk prediction models and published before November 21, 2019, were selected. Information form was created based on the CHARMS checklist. The PROBAST was used to assess the risk of bias. 12 eligible articles were identified, describing 15 prediction models, of which five were established in China. The predicted outcomes included multiple stages from cervical precancerous lesions to cancer occurrence, ., abnormal Pap smear (1), occurrence or recurrence of CIN (9), and occurrence of cervical cancer (5), . The most frequently used predictors were HPV infection (12), age (7), smoking (5), and education (5). There were two models using machine learning to develop models. In terms of model performance, the discrimination ranged from 0.53 to 0.87, while only two models assessed the calibration correctly. Only two models were externally validated in Taiwan of China, using people in different periods. All of the models were at high risk of bias, especially in the analysis domain. The problems were concentrated in the improper handling of missing data (13), preliminary evaluation of model performance (13), improper use of internal validation (12), and insufficient sample size (11). In addition, the problems of inconsistency measurements of predictors and outcomes (8) and the flawed report of the use of blindness for outcome measures (8) were also severe. Compared with the other models, the Rothberg (2018) model had relatively high quality. There are a certain number of cervical cancer risk prediction models, but the quality is poor. It is urgent to improve the measurement of predictors and outcomes, the statistical analysis details such as handling missing data and evaluation of model performance and externally validate existing models to better guide screening.

Meta-Analysis
We performed a systematic review and meta-analysis to evaluate the accuracy of screening cervical cancer tests as alternative standalone methods. The combined estimates of sensitivity of visual inspection with acetic acid, visual inspection with lugol's iodine, conventional pap smear, liquid-based cytology, High risk HPV testing by clinician, High risk HPV testing by self- sampling, cervicography were 64%, 80%, 55%, 70%, 70% and 67% respectively; the combine values of specificity of these screening strategies were 88%, 88%, 96%, 59%, 94%, and 95% respectively. Our findings draw attention to an attractive opinion to facilitate the collection of specimens for DNA HPV by patients in settings where they don't have access to a regular screening programs.
