Knowledge of cytology results affects the performance of colposcopy: a crossover study.

OBJECTIVE: To determine whether knowledge of cytology affects the colposcopist's diagnostic accuracy in the identification of cervical intraepithelial neoplasia grade 2 and worse (≥ CIN2). METHOD: In this cross-over study, healthcare professionals interpreted colposcopy images from 80 patient cases with known histological diagnoses. For each case, 2 images taken with a colposcope were provided (native and after acetic acid application). Inclusion criteria consisted of women with a transformation zone type 1 or 2, who had both a cytological and histological diagnosis. Cases were distributed across two online surveys, one including and one omitting the cytology. A wash-out period of six weeks between surveys was implemented. Colposcopists were asked to give their diagnosis for each case as < CIN2 or ≥ CIN2 on both assessments. Statistical analysis was conducted to compare the two interpretations. RESULTS: Knowledge of cytology significantly improved the sensitivity when interpreting colposcopic images, from 51.1% [95%CI: 39.3 to 62.8] to 63.7% [95%CI: 52.1 to 73.9] and improved the specificity from 63.5% [95%CI: 52.3 to 73.5] to 76.6% [95%CI: 67.2 to 84.0]. Sensitivity was higher by 38.6% when a high-grade cytology (ASC-H, HSIL, AGC) was communicated compared to a low-grade cytology (inflammation, ASC-US, LSIL). Specificity was higher by 31% when a low-grade cytology was communicated compared to a high-grade. CONCLUSIONS: Our data suggests that knowledge of cytology increases sensitivity and specificity for diagnosis of ≥ CIN2 lesions at colposcopy. Association between cytology and histology may have contributed to the findings.

Assessing colposcopy competencies in medically underserved communities: a multi-center study in China.

BACKGROUND: Colposcopy plays an essential role in diagnosing cervical lesions and directing biopsy; however, there are few studies of the capabilities of colposcopists in medically underserved communities in China. This study aims to fill this gap by assessing colposcopists' competencies in medically underserved communities of China. METHODS: Colposcopists in medically underserved communities across China were considered eligible to participate. Assessments involved presenting participants with 20 cases, each consisting of several images and various indications. Participants were asked to determine transformation zone (TZ) type, colposcopic diagnoses and to decide whether biopsy was necessary. Participants are categorized according to the number of colposcopic examinations, i.e., above or below 50 per annum. RESULTS: There were 214 participants in this study. TZ determination accuracy was 0.47 (95% CI 0.45,0.49). Accuracy for colposcopic diagnosis was 0.53 (95% CI 0.51,0.55). Decision to perform biopsies was 0.73 accurate (95% CI 0.71,0.74). Participants had 0.61 (95% CI 0.59,0.64) sensitivity and a 0.80 (95% CI 0.79,0.82) specificity for detecting high-grade lesions. Colposcopists who performed more than 50 cases were more accurate than those performed fewer across all indicators, with a higher sensitivity (0.66 vs. 0.57, p = 0.001) for detecting high-grade lesions. CONCLUSIONS: In medically underserved communities of China, colposcopists appear to perform poorly at TZ identification, colposcopic diagnosis, and when deciding to biopsy. Colposcopists who undertake more than 50 colposcopies each year performed better than those who perform fewer. Therefore, colposcopic practice does improve through case exposure although there is an urgent need for further pre-professional and clinical training.

Agreement on Lesion Presence and Location at Colposcopy.

OBJECTIVES/PURPOSE: The reproducibility and sensitivity of image-based colposcopy is low, but agreement on lesion presence and location remains to be explored. Here, we investigate the interobserver agreement on lesions on colposcopic images by evaluating and comparing marked lesions on digitized colposcopic images between colposcopists. METHODS: Five colposcopists reviewed images from 268 colposcopic examinations. Cases were selected based on histologic diagnosis, i.e., normal/cervical intraepithelial neoplasia (CIN)1 ( n = 50), CIN2 ( n = 50), CIN3 ( n = 100), adenocarcinoma in situ ( n = 53), and cancer ( n = 15). We obtained digitized time-series images every 7-10 seconds from before acetic acid application to 2 minutes after application. Colposcopists were instructed to digitally annotate all areas with acetowhitening or suspect of lesions. To estimate the agreement on lesion presence and location, we assessed the proportion of images with annotations and the proportion of images with overlapping annotated area by at least 4 (4+) colposcopists, respectively. RESULTS: We included images from 241 examinations (1 image from each) with adequate annotations. The proportion with a least 1 lesion annotated by 4+ colposcopists increased by severity of histologic diagnosis. Among the CIN3 cases, 84% had at least 1 lesion annotated by 4+ colposcopists, whereas 54% of normal/CIN1 cases had a lesion annotated. Notably, the proportion was 70% for adenocarcinoma in situ and 71% for cancer. Regarding lesion location, there was no linear association with severity of histologic diagnosis. CONCLUSION: Despite that 80% of the CIN2 and CIN3 cases were annotated by 4+ colposcopists, we did not find increasing agreement on lesion location with histology severity. This underlines the subjective nature of colposcopy.

Colposcopy-A Valuable Diagnostic Tool for Pregnant Women With Unexplained Vaginal Bleeding.

OBJECTIVES: We aimed to examine the diagnostic value of colposcopy in a large cohort of pregnant women with unexplained vaginal bleeding during the second or third trimester. MATERIALS AND METHODS: This retrospective study included women who underwent colposcopy due to vaginal bleeding in the second and third trimesters during 2012-2022 at a tertiary care hospital. Demographics, obstetric data, bleeding characteristics, colposcopy results, cervical cytology testing, a sonogram directed at the placenta, and birth details were collected. RESULTS: In total, 364 women were included. The mean maternal age was 29.7 years and the mean gestational age at examination was 30.7 weeks. Vaginal bleeding was mild in 80.8%, moderate in 14.6%, and severe in 4.7%. Only 3.3% had been vaccinated against human papilloma virus and 25.5% underwent a Pap smear study before pregnancy. Colposcopy diagnosed the bleeding source in 83 women (22.8%). The colposcopic examination revealed vaginal bleeding due to contact bleeding from ectropion in 46 (12.6%), a decidual/cervical polyp in 37 (10.2%), acetowhite epithelium in 12 (3.3%), herpes genetalis in 2 (0.5%), and bleeding from vaginal varices in 2 (0.5%). Of those who were recommended a follow-up examination after the postpartum period, only 49.1% completed such.Among women with compared to without postcoital bleeding ( N = 72), the risk of abnormal colposcopic findings was higher (24 [33.3%] vs 54 [19.7%], p = .017) and the rate of abnormal Pap smear was higher (7 [13.2%] vs 7 [3.2%], p = .008). CONCLUSIONS: Colposcopy can be a valuable diagnostic tool for women with unexplained vaginal bleeding in the second or third trimester.

The CryoPop study: Screening for high-grade cervical dysplasia in Karnataka, India.

OBJECTIVE: To describe our experience of screening with visual inspection with acetic acid (VIA) and colposcopy to identify women with high-grade precancerous cervical lesions who were candidates for cryotherapy. Women were screened to determine eligibility for a clinical trial testing the safety and efficacy of a new, simple and inexpensive cryotherapy device (CryoPop®) targeted for use in low and middle-income countries (LMICs). DESIGN: Prospective cohort study. SETTING: Primary and urban health centres in Belagavi, Hubballi and Vijayapur, India. POPULATION: Women in the age-group 30-49 years, premenopausal, with no prior hysterectomy and no known HIV infection were eligible for screening. METHODS: Visual inspection with acetic acid was performed on eligible women following informed consent. VIA-positive women were referred for colposcopy and biopsy. Biopsies were read by two pathologists independently, with a third pathologist acting as tie-breaker if needed. MAIN OUTCOME MEASURES: The primary outcome measures were the number/proportion of women screening positive by VIA and the number/proportion of those women screening VIA-positive found to have high-grade cervical lesions on biopsy (cervical intraepithelial neoplasia 2/3 [CIN 2/3]). Demographic variables were compared between women who screened VIA-positive and those who screened VIA-negative; a separate comparison of demographic and limited reproductive variables was performed between women who had CIN 2/3 on biopsy and those without CIN 2/3 on biopsy. Chi-square or Fisher's exact tests for categorical data and t-tests or analysis of variance for numeric data were used with all tests two-sided and performed at an alpha 0.05 level of statistical significance. RESULTS: A total of 9130 women were screened with VIA between 4 July 2020 and 31 March 2021. The mean age of all women screened was 37 years (standard deviation = 5.6 years) with 6073 of the women (66.5%) in the 30-39 year range. Only 1% of women reported prior cervical cancer screening. A total of 501 women (5.5%) were VIA-positive; of these, 401 women underwent colposcopy. Of those who had colposcopy, 17 (4.2%) had high-grade lesions on biopsy, an additional 164 (40.9%) had low-grade cervical lesions on biopsy or endocervical curettage and one woman (0.2%) was found to have invasive cancer. VIA-positive women were younger and had higher levels of education and income; however, women who were VIA-positive and found to have CIN 2/3 were older, were more likely to be housewives and had higher household income than those without CIN 2/3. CONCLUSION: Despite the COVID-19 pandemic, over 9100 women were screened with VIA for precancerous lesions. However, only 17 (4.2%) were found to have biopsy-proven high-grade cervical lesions, underscoring the subjective performance of VIA as a screening method. Given that this is significantly lower than rates reported in the literature, it is possible that the prevalence of high-grade lesions in this population was impacted by screening a younger and more rural population. This study demonstrates that screening is feasible in an organised fashion and can be scaled up rapidly. However, while inexpensive and allowing for same-day treatment, VIA may be too subjective and have insufficient accuracy clearly to identify lesions requiring treatment, particularly in low-prevalence and low-risk populations, calling into question its overall cost-effectiveness.

How to make a LLETZ simulator: LLETZ Simulator.

Large loop excision of the transformation zone (LLETZ) of the uterine cervix is a surgical procedure very frequently performed. Simulation of LLETZ under colposcopic guidance has a major role in training practitioners. The objective was to present an ex vivo model of LLETZ.

Colposcopy in the Primary Health Care: A Scoping Review.

AIM: Low- and middle-income countries represent nearly 85% of all cervical cancer cases worldwide; thereby, it is extremely important to identify methods to improve the screening process. Therefore, this study aimed to summarize the primary characteristics of studies on accessibility, coverage, patient preferences, and factors associated with patient satisfaction or acceptance of colposcopy in primary healthcare. METHODS: A search strategy, based on MeSH, Emtree, and free terms, was run through 5 databases (PubMed, Scopus, Embase, Ovid/Medline, and Web of Science). EndNote 20.1 © and Rayyan QCRI © were used for screening. A preset datasheet was used for data extraction. RESULTS: The systematic search retrieved 1127 references, and after removing duplicates, screening the titles and abstracts, and reviewing the full text, 7 studies were included. The interrater reliability was 77.73% (kappa statistic = 0.1842). Most studies estimated the proportion of women that sought for colposcopy after a previous screening test for human papilloma virus. One study identifies barriers to colposcopy examination in women at risk of developing cervical cancer. Three studies assessed the decentralization of colposcopy from a tertiary healthcare center to a primary care center. Pap smear was the most common first-line screening test, followed by liquid-based cytology sample and visual inspection with acetic acid. CONCLUSION: Only a few countries have investigated the use of colposcopy in primary care. Thus, barriers and the care structure for this implementation to be successful in reducing cervical cancer incidence and mortality should be identified.

The Triaging Effect of the Human Papillomavirus 16/18 E7 Oncoprotein Assay in HPV 16/18-Positive Patients for High-Grade Cervical Intraepithelial Neoplasia Screening: A Cross-Sectional Study.

Objective: To investigate the triaging efficacy of the human papillomavirus (HPV) 16/18 E7 oncoprotein assay for high-grade cervical intraepithelial neoplasia (CIN2+) screening in HPV 16/18-positive patients in a tertiary hospital in China. Methods: We collected 476 cervical cell samples from women who tested positive for HPV 16/18 in the gynecological clinic of Peking Union Medical College Hospital between September 2018 and September 2022 and analyzed them by the HPV 16/18 E7 oncoprotein assay before colposcopy and biopsy. The study assessed the triaging efficacy of the HPV 16/18 E7 oncoprotein assay in HPV 16/18-positive patients by analyzing its performance against the gold standard of histologically confirmed CIN2+. Results: The positive rate of the HPV 16/18 E7 oncoprotein assay was 41.0% (114/278) in the negative for intraepithelial lesions and malignancy/CIN1 group and 80.3% (159/198) in the CIN2+ group. For triage of women with a positive HPV 16/18 test for CIN2+ detection, the HPV 16/18 E7 oncoprotein assay had a sensitivity, specificity, positive predictive value, and negative predictive value of 80.3%, 59.4%, 58.5%, and 80.9%, respectively. Furthermore, longitudinal follow-up of five patients showed a good correlation between the expression of the HPV 16/18 E7 oncoprotein and cervical lesion grades. Conclusions: As a triage method for HPV 16/18-positive patients, the HPV 16/18 E7 oncoprotein assay improves the specificity, reduces the colposcopy referral rate, and has the potential for long-term monitoring of high-grade CIN.

¿Está la virtud en el punto medio? La incertidumbre del CIN2 y el papel del VPH / Is virtue at the midpoint? The uncertainty of CIN2 and the role of HPV

Objetivo: La biopsia guiada por colposcopia (BGC) marca el manejo de la neoplasia intraepitelial cervical. El objetivo de este estudio fue evaluar la concordancia de los resultados entre la BGC y la escisión amplia de la zona de transformación (LLETZ, large loop excision of the transformation zone), y la utilidad del genotipado del virus del papiloma humano (VPH) para seleccionar a las pacientes con riesgo de lesión intraepitelial escamosa de alto grado/neoplasia intraepitelial cervical 3 (HSIL/CIN3). Método: Se compararon los resultados de la BGC y de la LLETZ, siendo esta última el método de referencia. Se evaluó la relación del genotipo del VPH con el diagnóstico final de HSIL/CIN3. Resultados: La precisión de la biopsia comparada con LLETZ fue del 61,4%. La tasa de concordancia fue del 64,4% para CIN1, del 31,4% para CIN2 y del 77,4% para CIN3. La tasa global de sobrediagnóstico fue del 18,68% y la de subdiagnóstico del 19,89%. En mujeres menores de 30 años, la concordancia fue del 62,79% (CIN1 65%, CIN2 39,58% y CIN3 73,08%), la tasa de sobrediagnóstico del 22,67% y la tasa de subdiagnóstico del 15,11%. La infección por VPH16 tuvo una odds ratio de 3,86 para el diagnóstico final de HSIL/CIN3+. Conclusiones: El diagnóstico de CIN2 por BGC parece insuficiente para seleccionar a las pacientes para tratamiento escisional, principalmente en mujeres jóvenes. El hallazgo de VPH16 es un factor de riesgo de HSIL/CIN3+ independientemente del resultado de la biopsia.

Objective: Colposcopy-guided biopsy (CGB) is a basic tool for the management of cervical intraepithelial neoplasia. The aim of this study is to evaluate the concordance of results between CGB and large loop excision of the transformation zone (LLETZ), and the usefulness of human papillomavirus (HPV) genotyping to select patients at risk of H-SIL/CIN3. Method: The results of colposcopy-guided biopsy and LLETZ were compared, with LLETZ being the gold standard. The relationship of HPV genotype to the final diagnosis of CIN3 was assessed. Results: The accuracy of CGB compared to LLETZ was 61.4%. The concordance rate was 64.4% for CIN1, 31.4% for CIN2 and 77.4% for CIN3. The overall overdiagnosis rate was 18.68% and underdiagnosis rate was 19.89%. In women under 30 years of age the concordance rate was 62.79% (CIN1 65%, CIN2 39.58% and CIN3 73.08%), and the rate of overdiagnosis and underdiagnosis was 22.67% and 15.11%, respectively. HPV16 infection had an odds ratio of 3.86 for the final diagnosis of CIN3+ and the result was significant regardless of the biopsy result. Conclusions: The CGB result as CIN2 is inaccurate and seems insufficient to select patients for excisional treatment, mainly in young women. HPV16 infection is a risk factor for CIN3+ regardless of the colposcopy-guided biopsy result.

[Analysis of natural regression and influencing factors of HSIL in the cervix of childbearing age patients].

Objective: To investigate the natural regression and related factors of high-grade squamous intraepithelial lesion (HSIL) in the cervix of childbearing age women, and to evaluate the applicability of conservative management for future fertility needs. Methods: This study included 275 patients of reproductive age with fertility needs, who were diagnosed as HSIL by biopsy from April 30, 2015 to April 30, 2022, including 229 cases (83.3%) cervical intraepithelial neoplasia (CIN) Ⅱ and 46 cases (16.7%) CIN Ⅱ-Ⅲ. They were followed-up without immediate surgery in the First Affiliated Hospital of Nanjing Medical University. The median follow-up time was 12 months (range: 3-66 months). The regression, persistence and progression of lesions in patients with HSIL were analyzed during the follow-up period, the influencing factors related to regression and the time of regression were analyzed. Results: (1) Of the 275 HSIL patients, 213 cases (77.5%, 213/275) experienced regression of the lesion during the follow-up period. In 229 CIN Ⅱ patients, 180 cases (78.6%) regressed, 21 cases (9.2%) persisted, and 28 cases (12.2%) progressed. In 46 CIN Ⅱ-Ⅲ patients, 33 cases (71.7%) regressed, 12 cases (26.1%) persisted, and 1 case (2.2%) progressed to invasive squamous cell carcinoma stage Ⅰ a1. There was no significant difference in the regression rate between the two groups (χ2=1.03, P=0.309). (2) The average age at diagnosis, age <25 years old at diagnosis were independent influencing factor of HSIL regression in univariate analysis (all P<0.05). There was no significant difference between HSIL regression and pathological grading, the severity of screening results, human papillomavirus (HPV) genotype, colposcopy image characteristics, number of biopsies during follow-up and pregnancy experience (all P>0.05). (3) The median regression times for patients aged ≥25 years and <25 years at diagnosis were 15 and 12 months, respectively. Kaplan-Meier analysis showed that age ≥25 years at diagnosis significantly increased the median regression time compared to <25 years (χ2=6.02, P=0.014). Conclusions: For HSIL patients of childbearing age, conservative management without immediate surgical intervention is preferred if CINⅡ is fully evaluated through colposcopy examination. Age ≥25 years at diagnosis is a risk factor affecting the prognosis of HSIL patients.

Enhancing colposcopy training using a widely accessible digital education tool in China.

BACKGROUND: Colposcopy is a cornerstone of cervical cancer prevention; however, there is a global shortage of colposcopists. It is challenging to train a sufficient number of colposcopists through in-person methods, which hinders our ability to adequately diagnose and manage positive cases. A digital platform is needed to make colposcopy training more efficient, scalable, and sustainable; however, current online training programs are generally based on didactic curricula that do not incorporate image analysis training. In addition, long-term assessments of online training are not readily available. Therefore, innovative digital training and an assessment of its effectiveness are needed. OBJECTIVE: This study aimed to evaluate the short- and long-term effects of DECO (an online Digital Education Tool for Colposcopy) on trainees' colposcopy competencies and confidence. STUDY DESIGN: DECO can be used both on laptops and smartphones and comprises 4 training modules (image interpretation; terminology learning; video teaching; and collection of guidelines and typical cases) and 2 test modules. DECO was tested through a pre-post study between September and November 2022. Participants were recruited in China, and DECO training lasted 12 days. Trainees initially learned basic theory before completing training using 200 image-based cases. Pretest, posttest, and follow-up testing included 20 distinct image-based questions, and was conducted on Days 0, 13, and 60. Primary outcomes were competence and confidence scores. Secondary measures were response distributions for colposcopic diagnoses, biopsies, and DECO training satisfaction. Multilevel modeling was used to determine improvement from baseline to posttraining and follow-up for the outcomes of interest. RESULTS: Among 402 participants recruited, 96.8% (n=389) completed pretesting, 84.1% (n=338) posttesting, and 75.1% (n=302) follow-up testing. Colposcopic competence and confidence increased across this study. Diagnostic scores improved on average from 55.3 (53.7-56.9) to 70.4 (68.9-71.9). The diagnostic accuracy for normal/benign lesions, low-grade squamous intraepithelial lesions, and high-grade squamous intraepithelial lesions or worse increased by 16.9%, 13.1%, and 16.9%, respectively. Mean confidence scores increased from 48.1 (45.6-50.6) to 56.2 (54.5-57.9). These improvements remained evident 2 months after training. Trainees were also satisfied with DECO overall. Most found DECO to be scientific (82.5%), easy to use (75.2%), and clinically useful (98.4%), and would recommend it to colleagues (93.2%). CONCLUSION: DECO is a useful, acceptable digital education tool that improves colposcopy competencies and confidence. DECO could make colposcopy training more efficient, scalable, and sustainable because there are no geographic or time limitations. Therefore, DECO could be used to alleviate the shortage of trained colposcopists around the world.

Does the New National Cervical Screening Programme Guideline Detect Cases of High-Grade Squamous Intraepithelial Lesions That Previously Would Have Been Missed?

OBJECTIVE: The aim of this study was to determine the number of patients undergoing large loop excision of the transformation zone (LLETZ), for biopsy-confirmed high-grade squamous intraepithelial lesions (HSIL), where the original cervical screening test (CST) reported oncogenic human papillomavirus (HPV) and negative liquid-based cytology (LBC). This reflects the number of patients where a LLETZ procedure would not have occurred under the previous guideline. METHODS: Retrospective observational chart review of all patients (n = 477) who underwent LLETZ procedure in a single tertiary unit over a 36-month period. Prevalence of negative histopathology, positive margins, incidental cervical cancer, and accuracy of HSIL identification at colposcopy were measured. Diagnostic accuracy of HSIL diagnosis from initial colposcopic impression was calculated; factors influencing accuracy were evaluated using multivariable logistic regression analysis. There were no comparators. RESULTS: Of 477 LLETZs, 5.9% (n = 28) were for oncogenic HPV and normal LBC on referral CST. Demographics between the "study" (oncogenic HPV and normal LBC on referral CST) and the "standard" group were similar, except the study group was less likely to be using contraception (25% vs 47%, p = .023). In the study group, initial colposcopic cervical biopsy confirmed HSIL in 91.6% (n = 27) and low-grade squamous intraepithelial lesions in 3.6% (n = 1). Histopathological analysis of LLETZ specimens confirmed HSIL in 20 patients (71.4%) and low-grade squamous intraepithelial lesions in 2 (7.1%). No microinvasion was detected. CONCLUSIONS: The renewed National Cervical Screening Programme (NCSP), is detecting more "at risk" patients, predicted to lead to a further reduction in incidence of cervical cancer in adequately screened patients.

Insufficient training in colposcopy and loop electrosurgical excision procedure among residents.

INTRODUCTION: Colposcopy is an important tool in the diagnostic work-up of women with an abnormal cervical smear. Unlike in other countries where colposcopy is mostly performed by certified colposcopists, in Denmark, colposcopy may be performed by residents in obstetrics and gynaecology (OB/Gyn). We aimed to evaluate training in colposcopy and loop electrosurgical excision procedure (LEEP) among Danish OB/Gyn residents. METHODS: Two questionnaires were developed: one for OB/Gyn residents who are required to learn colposcopy and LEEP during their residency, and one for chief physicians who are responsible for providing their training. Questionnaires were distributed by e-mails and via social media from November to December 2021. RESULTS: Among 120 eligible residents, 93 completed the questionnaire. The median age was 36 (interquartile range: 34-39) years. Most received training in colposcopy (84.9%), but the majority considered training to be insufficient (76.3%) and had low self-efficacy in performing colposcopy (72.0%). With respect to LEEP, most received training (84.9%), but nearly half considered that their training had been insufficient (43.0%) and had low self-efficacy in performing LEEP (49.5%). CONCLUSIONS: Most Danish OB/Gyn residents receive insufficient training in colposcopy and LEEP, which demonstrates a need for a formal training programme for residents and their supervisors to ensure an appropriate level of training and adequate patient care.

A cross-sectional survey examining clinician characteristics, practices, and attitudes associated with adoption of the 2019 American Society for Colposcopy and Cervical Pathology risk-based management consensus guidelines.

BACKGROUND: The 2019 American Society for Colposcopy and Cervical Pathology (ASCCP) risk-based management consensus guidelines are the most recent national guidelines for the management of abnormal cervical cancer screening tests. These guidelines benefit patients by concentrating testing and treatment in those at highest cervical cancer risk. Adoption of guidelines often occurs slowly, with few studies examining the factors associated with guideline-adherent management of abnormal results. METHODS: To elucidate the factors associated with the use of the 2019 ASCCP guidelines among clinicians who perform cervical cancer screening, physicians and advanced practice professionals who perform cervical cancer screening were cross-sectionally surveyed. Clinicians responded to screening vignettes with differing recommendations for management between the 2019 and prior management guidelines. Screening vignette 1 involved reduction of invasive testing on a low-risk patient; screening vignette 2 involved increased surveillance testing on a high-risk patient. Binomial logistic regression models determined the factors associated with the use of the 2019 guidelines. RESULTS: A total of 1251 clinicians participated from across the United States. For screening vignettes 1 and 2, guideline-adherent responses were given by 28% and 36% of participants, respectively. Management recommendations differed by specialty and were incorrect in different situations: there was inappropriate invasive testing by obstetrics and gynecology physicians (vignette 1) and inappropriate discontinuation of screening by family and internal medicine physicians (vignette 2). Regardless of their chosen response, over half erroneously believed they were guideline adherent. CONCLUSIONS: Many clinicians who believe they are following appropriate guidelines may not realize their management strategy is inconsistent with the 2019 guidelines. Education initiatives tailored to clinician specialty could address the understanding of current guidelines, encourage the use of updated guidelines, maximize patient benefits, and minimize harms. PLAIN LANGUAGE SUMMARY: The 2019 American Society for Colposcopy and Cervical Pathology risk-based management consensus guidelines are the most recent national guidelines for abnormal cervical cancer screening test management. We surveyed over 1200 obstetrics and gynecology (OB/GYN), family medicine, and internal medicine physicians and advanced practice providers about their screening and abnormal results follow-up practices in relation to guidelines. Few clinicians are following the 2019 guidelines. Management recommendations differed by clinician specialty and were incorrect in different situations: there was inappropriate invasive testing by OB/GYN physicians and inappropriate screening discontinuation by family and internal medicine physicians. Education tailored by clinician specialty could address the understanding of current guidelines, encourage the use of updated guidelines, maximize patient benefits, and minimize harms.

Câncer de colo uterino na gestação / Cervical cancer in pregnancy

PONTOS-CHAVE • A incidência de câncer durante a gestação tem aumentado devido à tendência das mulheres em postergar a gravidez. O câncer de colo de útero é a terceira neoplasia mais comumente diagnosticada durante o período gestacional. • O rastreamento e o diagnóstico devem se dar como nas pacientes não gestantes; a citologia oncótica cervical é o exame obrigatório do pré-natal, e a colposcopia com biópsia pode ser realizada em qualquer período da gestação. • A gestação complicada pelo diagnóstico de um câncer deve sempre ser conduzida em centro de referência e por equipe multidisciplinar. • A interrupção da gestação em situações específicas, para tratamento-padrão, é respaldada por lei. • A quimioterapia neoadjuvante é uma alternativa segura de tratamento durante a gestação, para permitir alcançar a maturidade fetal. Apresenta altas taxas de resposta, sendo relatada progressão neoplásica durante a gestação em apenas 2,9% dos casos. O risco de malformações fetais decorrentes da quimioterapia é semelhante ao da população geral. Contudo, a quimioterapia está associada a restrição de crescimento intraútero, baixo peso ao nascer e mielotoxicidade neonatal. • Na ausência de progressão de doença, deve-se levar a gestação até o termo.

Cost-Conscious Colposcopy: A Single-Institution Review of Biopsy Submission Practices and Outcomes.

OBJECTIVE: Distribution of cervical dysplasia may influence approach for excisional procedures. Separating colposcopy biopsies into multiple specimen cups for pathologic evaluation incurs additional costs. The authors aimed to determine whether the practice of separating biopsy specimens impacts patient outcomes. METHODS: A retrospective review of all colposcopy cases from a single institution was performed. A total of 1,331 cases were reviewed from January 1, 2017, to December 31, 2019. Multibiopsy cohorts were separated by number of specimen cups received by pathology (single or multiple). Cohorts were compared for histology, need for excisional procedure, and final excisional pathology results. Specimen processing fees were acquired from the Department of Pathology ($70/specimen). Statistical analysis performed on MINITAB using Pearson chi-square and Fisher exact tests. RESULTS: Excisional procedures were required by 30.4% (86/283) of multiple specimen submissions compared with 28.2% (154/547) of single specimen cup submissions ( p = .50). There was a higher, although not statistically significant, rate of additional procedures in the multiple specimen cup cohort (8.8 vs 2.9% [ p = .08]). Malignancy diagnosis was equivalent in each cohort. Cost analysis revealed adopting a single specimen cup model would reduce costs up to approximately $30,000/year. CONCLUSIONS: Patient outcomes were not improved by the practice of submitting multiple specimen cups. Given the additional cost associated with separating specimens, the authors recommend during routine colposcopy that all cervical biopsies be sent for evaluation as a single pathology specimen unless a lesion of concern is identified in an area not normally excised during traditional excisional procedures.

HPV Cotesting of Unsatisfactory Papanicolaou Tests: Implications for Follow-up Intervals.

OBJECTIVES: The 2019 American Society of Colposcopy and Cervical Pathology management guidelines recommend that patients with an unsatisfactory Papanicolaou (Pap) test (UPT) and negative human papillomavirus (HPV) cotest undergo repeat age-based screening in 2 to 4 months. The rationale is that a negative HPV test in the setting of an UPT may reflect an inadequate sample and therefore should not be interpreted as truly "negative." For patients 25 years and older who are cotested, if HPV is positive for the 16 or 18 genotypes, direct referral for colposcopy is recommended. Our study aimed to determine if a negative HPV cotest result is predictive of the absence of a high-grade squamous intraepithelial lesion (HSIL) and whether these patients may be called back for repeat testing at an interval longer than 2 to 4 months. METHODS: Follow-up cervical cytology and biopsy results in women with UPT and HPV cotests from January 2017 to December 2021 were collected. Original UPT and HPV cotest results were correlated with the follow-up Pap and biopsy results. RESULTS: There were 1,496 (2.28%) UPT cases out of 65,641 total Pap tests. Among the 1,496 UPT cases, 1,010 (67.5%) had HPV cotesting; 676 (45.1%) were followed by repeat Pap or biopsy within 4 months and 850 (56.8%) within 12 months. The total follow-up rate was 81%, with a range of 3 days to 36 months. The HSIL rate in HPV-positive cases was 5.7% (3/53) vs 0.4% (2/539) (P = .006) in HPV-negative cases. In UPT, HPV cotesting showed negative predictive values for low-grade and high-grade squamous intraepithelial lesion detection of 98.5% and 99.6%, respectively, while positive predictive values were 19% and 5.7%. CONCLUSIONS: A negative HPV cotest in individuals with UPT predicted the lack of HSIL in our study. Compliance with the recommended follow-up time of 2 to 4 months for women with UPT was low (45.1%). Our study suggests that women with UPT and negative HPV cotest may be safely called back at an interval longer than 4 months.

Cervical intraepithelial neoplasia in non-16/18 high-risk human papilloma virus positive/cytology negative women: An alternative approach in poor resource areas.

OBJECTIVE: Because the specific prevalence and carcinogenesis of non-16/18 high-risk (hr) Human Papillomavirus (HPV) is not fully understood, we designed a study with aim of evaluating the risk of high-grade cervical intraepithelial neoplasia (CIN) in non-16/18 hr-HPV positive/cytology negative cases and assessing the distribution of non-16/18 hr-HPV subtypes. MATERIALS AND METHODS: This cross-sectional study was conducted on 138 non-16/18 hr-HPV positive/cytology negative women, who were referred to the gynecologic oncology clinic of Yas hospital, affiliated with Tehran University of Medical Sciences, January 2021 to 2022. RESULTS: Among the detected types, HPV 31 was the most frequent type. 63 cases underwent biopsy as indicated based on colposcopic examination with acetic acid 3% application among which 34 had normal results. In the remaining 29 cases, 25 had insignificant findings. CIN2 was reported in 2 cases, one with HPV 31, 45, 58, and the other with HPV 58. CIN3 was also detected in 2 cases, one with HPV 31 and the other with HPV 35, 45. The overall incidence of high-grade CIN was 2.8%. A statistically significant (P-value = 0.046) difference was detected between patients with high-grade CIN compared with the others regarding the Hookah usage. CONCLUSION: The risk of CIN among non-16/18 hr-HPV positive/cytology negative cases is noticeably low. Based on ASCCP guidelines return testing at 1 year without immediate colposcopy seems sufficient; however, because of many reasons doing immediate colposcopy rather than 1-year follow-up may be a more accessible approach in resource poor, low-income countries such as ours.

[Revision of the French colposcopic terminology]. / Nouvelle classification française des images colposcopiques.

OBJECTIVES: To revise the 1983 colposcopic terminology form the French Society of Colposcopy and cervicovaginal pathology (SFCPCV). METHODS: All the three following steps of colposcopic examination were considered for the description of various colposcopic features: inspection without coloration, followed by the application of acetic acid and iodine staining. This revised terminology now includes the different possible colposcopic aspects of the normal cervix, including the ectropion and the normal transformation zone. It also includes colposcopic appearance of abnormal glandular cervical epithelium and of vaginal epithelium. The revised nomenclature was reviewed by all the board of the SFCPCV and was finally approved during the 45th annual conference of the SFCPCV. RESULTS: Abnormal transformation zone grade (TAG) 1a and 1b have been brought together under the sole TAG1 designation. TAG2a and TAG2b now correspond to TAG2, whereas TAG2c corresponds to TAG3. Colposcopic report should mention the interpretability of the colposcopic examination, with the precise type of the squamocolumnar junction (1, 2 or 3), the colposcopic impression, the size of any TAG and finally mention whether one or multiple biopsies were taken and their precise location. Colposcopic impression must give priority to the most pejorative colposcopic aspect which takes precedence over others. CONCLUSION: When performing colposcopy, one should keep in mind that this examination only relies on the interpretation of various colposcopic signs and images with this not guaranteeing for diagnosis. Only histological analysis of a possible guided cervical biopsy provides for a precise diagnosis.

Accuracy of colposcopy in the Swedish screening program.

INTRODUCTION: Sensitivity and specificity of colposcopy vary greatly between studies and efficacy in clinical studies seldom corresponds with effectiveness in a real-life setting. It is unclear whether colposcopists' experience affects assessment; studies show divergent results. The study's objective was to investigate the accuracy of colposcopies in the Swedish screening program, the variability in colposcopists' assessments and whether degree of experience affects accuracy in a routine setting. MATERIAL AND METHODS: Cross-sectional register study. All colposcopic assessments with a concomitant histopathological sample from women aged at least 18 years, performed between 1999 and September 2020 in Sweden. The main outcome measure was accuracy. The accuracy of colposcopic assessments was calculated as overall agreement with linked biopsies, with three outcomes: Normal vs Atypical, Normal vs Low-Grade Atypical vs High-Grade Atypical, and Non-High-Grade Atypical vs High-Grade Atypical. A time-trend analysis was performed. The accuracy of identifiable colposcopists related to experience was analyzed. RESULTS: In total, 82 289 colposcopic assessments with linked biopsies were included for analysis of the outcome Normal vs Atypical; average accuracy was 63%. Overrating colposcopic findings was four times more common than underrating. No time trend in accuracy was noted during the study period. Accuracy in distinguishing High-Grade from Non-High-Grade lesions was better: 76%. Among identifiable colposcopists, overall accuracy was 67%. Some had significantly better accuracy than others, but no correlation with experience was found. CONCLUSIONS: Colposcopy, including in a referral setting, has low accuracy in distinguishing Normal from Atypical. Increased experience alone does not lead to improvement. This is supported by the substantial differences in performance between colposcopists.
