13-Type HPV DNA Test versus 5-Type HPV mRNA Test in Triage of Women Aged 25-33 Years with Minor Cytological Abnormalities-6 Years of Follow-Up.

BACKGROUND: A specific, cost-effective triage test for minor cytological abnormalities is essential for cervical cancer screening among younger women to reduce overmanagement and unnecessary healthcare utilization. We compared the triage performance of one 13-type human papillomavirus (HPV) DNA test and one 5-type HPV mRNA test. METHODS: We included 4115 women aged 25-33 years with a screening result of atypical squamous cells of undetermined significance (ASC-US) or low-grade squamous intraepithelial lesions (LSIL) recorded in the Norwegian Cancer Registry during 2005-2010. According to Norwegian guidelines, these women went to triage (HPV testing and repeat cytology: 2556 were tested with the Hybrid Capture 2 HPV DNA test, which detects the HPV types 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, and 68; and 1559 were tested with the PreTect HPV-Proofer HPV mRNA test, which detects HPV types 16, 18, 31, 33, and 45). Women were followed through December 2013. RESULTS: HPV positivity rates at triage were 52.8% and 23.3% among DNA- and mRNA-tested women (p < 0.001), respectively. Referral rates for colposcopy and biopsy and repeat testing (HPV + cytology) after triage were significantly higher among DNA-tested (24.9% and 27.9%) compared to mRNA-tested women (18.3% and 5.1%), as were cervical intraepithelial neoplasia grade 3 or worse (CIN3+) detection rates (13.1% vs. 8.3%; p < 0.001). Ten cancer cases were diagnosed during follow-up; eight were in DNA-tested women. CONCLUSION: We observed significantly higher referral rates and CIN3+ detection rates in young women with ASC-US/LSIL when the HPV DNA test was used at triage. The mRNA test was as functional in cancer prevention, with considerably less healthcare utilization.

Cervical Cancer Screening with DNA-HPV Testing and Precancerous Lesions Detection: A Brazilian Population-based Demonstration Study / Rastreamento do câncer do colo do útero com teste de DNA-HPV e detecção de lesões precursoras: um estudo de demonstração de base populacional brasileiro

Abstract Objective To evaluate the rates of precancerous lesions, colposcopy referral, and positive predictive value (PPV) by age groups of a population-based screening with DNA-HPV testing. Methods The present demonstration study compared 16,384 HPV tests performed in the first 30 months of the program with 19,992 women tested in the cytology screening. The colposcopy referral rate and PPV for CIN2+ and CIN3+ by age group and screening program were compared. The statistical analysis used the chi-squared test and odds ratio (OR) with 95% confidence interval (95%CI). Results The HPV tests were 3.26% positive for HPV16-HPV18 and 9.92% positive for 12 other HPVs with a 3.7 times higher colposcopy referral rate than the cytology program, which had 1.68% abnormalities. Human Papillomavirus testing detected 103 CIN2, 89 CIN3, and one AIS, compared with 24 CIN2 and 54 CIN3 detected by cytology (p < 0.0001). The age group between 25 and 29 years old screened by HPV testing had 2.4 to 3.0 times more positivity, 13.0% colposcopy referral, twice more than women aged 30 to 39 years old (7.7%; p < 0.0001), and detected 20 CIN3 and 3 early-stage cancer versus 9 CIN3 and no cancer by cytology screening (CIN3 OR= 2.10; 95%CI: 0.91 -5.25; p = 0.043). The PPV of colposcopy for CIN2+ ranged from 29.5 to 41.0% in the HPV testing program. Conclusion There was a significant increase in detections of cervix precancerous lesions in a short period of screening with HPV testing. In women < 30 years old, the HPV testing exhibited more positivity, high colposcopy referral rate, similar colposcopy PPV to older women, and more detection of HSIL and early-stage cervical cancer.

Resumo Objetivo Avaliar as taxas de lesões pré-cancerosas, encaminhamento para colposco pia e valor preditivo positivo (VPP) por faixas etárias de rastreamento populacional com teste DNA-HPV. Métodos O presente estudo de demonstração comparou 16.384 testes de HPV realizados nos primeiros 30 meses do programa com 19.992 mulheres testadas no rastreio citológico. Os programas foram comparados por taxa de encaminhamento de colposcopia e VPP para NIC2+ e NIC3+ por faixa etária. A análise estatística utilizou o teste de qui-quadrado e odds ratio (OR, na sigla em inglês) com intervalo de confiança (IC) de 95%. Resultados Os testes de HPV foram 3,26% positivos para HPV16-HPV18 e 9,92% positivos para 12 outros HPVs, com uma taxa de encaminhamento de colposcopia 3,7 vezes maior do que o programa de citologia, que teve 1,68% de anormalidades. O teste de HPV detectou 103 NIC2, 89 NIC3 e um AIS, em comparação com 24 NIC2 e 54 NIC3 detectados por citologia (p < 0,0001 ). O rastreio por teste de HPV no grupo etário 25 a 29 anos teve 2,4 a 3,0 vezes mais positividade, 13,0% de encaminhamento para colposcopia, 2 vezes mais que mulheres de 30 a 39 anos (7,7%; p < 0,0001 ), e detectou 20 NIC3 e 3 cânceres em estágio inicial versus nove NIC3 e nenhum câncer pelo rastreio citológico (NIC3 OR= 2,10; 96%CI: 0,91 -5,25; p = 0,043). O VPP da colposcopia para NIC2+ variou de 29,5 a 41,0% no programa de teste de HPV. Conclusão Houve um aumento significativo na detecção de lesões pré-cancerosas do colo do útero em um curto período de rastreamento com teste de HPV. Em mulheres < 30 anos, o teste de HPV exibiu mais positividade, alta taxa de encaminhamento para colposcopia com VPP semelhante a mulheres mais velhas, e mais detecção de HSIL e de câncer cervical em estágio inicial.

Evaluación clínica y análisis económico de la autotoma para la detección del Virus del Papiloma Humano / Clinical evaluation and economic analysis of self-testing for the detection of Human Papillomavirus

CONTEXTO: En el año 2020, 604 000 mujeres fueron diagnosticadas con cáncer de cuello uterino en el mundo y 342 000 murieron por esta enfermedad. En México, durante el año 2022 se estimaron un total de 9 439 nuevos casos y 4 335 muertes, una tasa de incidencia y mortalidad de 12.6 y 5. 7 por cada 100 000 habitantes, respectivamente. Chiapas fue el estado con mayor mortalidad del país con una tasa de 11.91 por cada 100 000 habitantes. Los programas de tamizaje efectivos reducen la mortalidad secundaria a CCU. La estrategia global de la OMS para la eliminación del cáncer de cuello uterino, establece que el 90% de las niñas deberán estar vacunadas antes de cumplir 15 años, 70% de las mujeres deberán ser examinadas con una prueba de alta precisión a los 35 años y una vez más a los 45 años y 90% de las mujeres diagnosticadas con lesiones precancerosas o cáncer de cuello del útero invasivo deberán recibir tratamiento. Las nuevas directrices para el tamizaje de CCU recomiendan la prueba de detección del ADN del VPH como el método de elección, ya que es más sensible y eficaz que otras pruebas y permite identificar con precisión a las mujeres con alto riesgo de desarrollar CCU. Una de las ventajas de la detección de VPH es que es la única prueba de tamizaje que puede realizarse con una muestra vaginal tomada por la propia paciente (autotoma vaginal, automuestreo o muestra autorecogida). La autotoma es un método en el cual, la paciente obtiene su propia muestra, vaginal o de orina, con ayuda de un kit especialmente diseñado para este propósito. En México se han identificado diversas razones que dificultan o impiden el tamizaje de CCU, entre las más comunes se encuentran la nula o difícil accesibilidad a los servicios de salud, incomodidad al momento de la toma de la muestra, desconocimiento sobre la utilidad o frecuencia con la que se debe de realizar el tamizaje, barreras ideológicas y culturales. Las mujeres que pertenecen a grupos socioeconómicos desfavorecidos son las más afectadas debido a las barreras de acceso a los servicios de salud. MÉTODOS: Se realizó una búsqueda sistemática en tres de las principales bases de datos bibliográficas: PubMed Central, Cochrane Library y la Biblioteca Virtual en Salud (BVS). La estrategia de búsqueda se realizó con vocabulario controlado (términos MeSH) y vocabulario libre. La búsqueda de la evidencia clínica fue limitada a documentos publicados entre el 1° de enero de 2018 y el 1° de marzo del 2023. Se realizó la selección por título y resumen, posteriormente, se revisaron los textos completos de los estudios potencialmente elegibles. En el mismo sentido, para la evidencia económica también se realizó una revisión sistemática, misma que incluyó a PubMed Central, Value in Health, University of York Centre of Reviews and Dissemination y ScienceDirect; sin restricción de fecha de publicación hasta junio de 2023. También se realizó la selección por título y resumen, para después revisar textos completos de estudios potencialmente elegibles. RESULTADOS: Tres y siete estudios transversales evaluaron la concordancia entre las muestras por autotoma y las muestras clínicas para la detección de VPH, un estudio reportó una concordancia regular (к= 0.34 y 0.40), el resto de moderada a sustancial (к= 0.47 a 0.72). En Arbyn, la concordancia general fue de 88.7% (IC del 95% 86.3 a 90.9), к= 0.72 (IC del 95% 0.66 a 0.78). Los valores de kappa no variaron significativamente según la prevalencia del VPH. Mientras que en Sy, el к agrupado fue de 0,66 (IC del 95 % de 0.61 a 0.71; I2=88%). En las poblaciones de riesgo el к fue de 0.63 (IC del 95 % de 0.56 a 0.71). Las pruebas de amplificación basadas en PCR tuvieron un desempeño mejor con un к de 0.68 (IC del 95 % de 0.63 a 0.73) en comparación con las pruebas de detección de ARNm (к=0.61, IC del 95% del 0.51 a 0.71). La revisión sistemática, Nodjikouambaye, к de los estudios fue heterogéneo, la concordancia reportada fue de moderada a sustancial, la menor concordancia se reportó en Olusegun et al. con un valor de к de 0.47 (IC del 95% de 0.21 a 0.72) y la mayor concordancia fue en Mbatha et al. y Untiet et al. con un к de 0.74 en cada estudio. En el estudio transversal Aranda, la concordancia general, con respecto a las muestras clínicas, fue de 78.2% (390/505), к= 0.34 (IC del 95% de 0.25 a 0.44), p=0.63 para la determinación de ADN del VPH y de 92.5% (467/505), к= 0.40 (IC del 95% de 0.25 a 0.56), p=0.23 para la prueba de ARNm. En Bokan, el porcentaje de concordancia entre la autotoma y las muestras clínicas fue de 81.8% (к=0.534) cuando se utilizó el dispositivo Qvintip y de 77.1% (к=0.45) con Herswab. Por su parte, Ngu mostró una concordancia general entre la autotoma y las muestras clínicas de 90.2% (IC del 95% de 85.1 a 93.8%), к= 0.59 (IC del 95% de 0.41 a 0.75). En Nutthachote se reportó un índice к= 0.73. En el estudio transversal Rohner la concordancia general entre los resultados de las muestras de orina y las muestras clínicas fue moderada (к= 0.54), el resultado fue similar cuando se comparó con las muestras de autotoma (к= 0.58). Por último, en Tranberg 2018, se observó una concordancia sustancial entre la autotoma vaginal y las muestras clínicas para la detección del VPH, con un índice к= 0.70 (IC del 95% de 0.58 a 0.81%). CONCLUSIONES: De acuerdo con la evidencia analizada, la concordancia de las muestras vaginales por autotoma y las muestras clínicas es aceptable, además del tipo de muestra, se debe considerar la eficacia para la detección de VPH, también es dependiente del tipo de estudio (PCR, captura de híbridos, detección de ARNm E6/E7, entre otros). Las pruebas de detección de VPH en muestras vaginales por autotoma mostraron una sensibilidad y especificidad de 80 a 96.5% y 78.9 a 90%, respectivamente. (Cabe mencionar que en el metaanálisis Sy, la sensibilidad de las muestras por autotoma fue en promedio 10% menor cuando se compara con las muestras clínicas, mientras que la especificidad es similar entre ambas muestras). Los estudios que analizaron muestras de orina autorecolectadas, mostraron una sensibilidad significativamente menor en comparación a las muestras clínicas (51.6 a 76% vs 88.9 a 97%) y una especificidad heterogénea (38.4% a 91.6%), por lo cual, no es posible recomendar su uso para la detección del VPH. En México, la cobertura de tamizaje para cáncer cervicouterino, es heterogénea, siendo mucho menor en las áreas rurales en comparación con zonas urbanas, lo anterior, incrementa el riesgo de morir por cáncer de cuello uterino hasta tres veces en las mujeres de zonas de bajos recursos. En contextos en los que no es posible realizar el tamizaje tradicional, la autotoma vaginal permite analizar las muestras de estas pacientes con una concordancia de regular a sustancial y una precisión diagnóstica similar a las muestras tomadas por personal médico. De manera general, la evidencia económica concluye que la autotoma puede ser costo ­ efectiva en comparación con las tomas de muestras convencionales en las pruebas de ADN y citología, al lograr mayores niveles de cobertura. Por ello, en México, se podría esperar que en aquellos lugares donde se tengan niveles bajos de cobertura respecto al tamizaje para VPH, pueda convertirse en una alternativa costo ­ efectiva.

Tamización primaria con prueba ADN-VPH en mujeres menores de 30 años: evaluación de tecnología sanitaria / Primary HPV-DNA screening in women under 30 years of age: health technology assessment

Antecedentes A partir del 2014 en Colombia se incorporó la Tamización primaria con prueba de Virus del Papiloma Humano (VPH) desde los 30 hasta los 65 años, cuando la prueba es positiva se hace triage con citología para remisión a colposcopia. Actualmente se discute la conveniencia de iniciar la tamización con prueba de ADN de VPH a partir de los 25 años. De esta manera, el objetivo de esta evaluación de tecnologías sanitarias es analizar la evidencia disponible en torno a la seguridad, efectividad, costoefectividad, valores y preferencias, dilemas éticos y aspectos relacionados con la implementación para el contexto colombiano de la prueba ADN-VPH como estrategia de tamización cervical en mujeres menores de 30 años. Dominios a evaluar Eficacia clínica y seguridad 1. Tasa acumulada de neoplasia intraepitelial cervical (NIC) grado 2 o más avanzado luego de 2 rondas de tamización. 2. Tasas acumuladas de cáncer invasor de cérvix luego de 2 rondas de tamización. 3. Seguridad: remisión a colposcopia. Costo-efectividad Costo efectividad para Colombia. Otros dominios considerados Aspectos éticos asociados a la tamización cervical en mujeres menores de 30 años. Aspectos organizacionales y del individuo. Barreras y facilitadores relacionados con la implementación en el contexto colombiano de la tamización cervical en mujeres menores de 30 años. Métodos Evaluación de efectividad y seguridad clínicas Se realizó una búsqueda sistemática de la literatura en MEDLINE, Embase y CENTRAL de revisiones sistemáticas y ensayos clínicos. Se calificó el cuerpo de la evidencia con la aproximación GRADE. Posteriormente, se convocó a un grupo interdisciplinario a una mesa de trabajo en donde se presentó la evidencia recuperada, dando paso a la discusión y a la construcción de las conclusiones, siguiendo los lineamientos de un consenso formal acorde a la metodología RAND/UCLA. Estudio económico Se hizo una búsqueda sistemática de la literatura de estudios que hubieran evaluado el costo-efectividad para Colombia. Resultados De 7.659 referencias recuperadas se incluyeron 8 estudios. Resultados clínicos Se realizó un análisis integrativo de 5 ensayos clínicos aleatorizados que cumplieron con los citerios de inclusión. Cuando se compara frente a la citología, la tamización primaria con ADN-VPH en mujeres menores de 30 años, podría asociarse con una mayor frecuencia de detección de lesiones NIC2+ durante la primera ronda de cribado (RR: 1.57; IC: 1,20 a 2,04; certeza en la evidencia baja), con una menor incidencia de NIC2+ (RR:0,67; IC: 0,48 a 0,92; certeza en la evidencia baja) y se asocia con una menor frecuencia de carcinoma invasor al término del seguimiento (RR: 0,19; IC: 0,07 a 0,53; certeza en la evidencia alta). Resultados económicos Desde el punto de vista económico, la alternativa de ADN-VPH y triage con citología desde los 25 años quizás representa la alternativa más costo-efectiva para Colombia (razón costo-efectividad incremental $8.820.980 COP año 2013). Otras implicaciones Dos estudios sugieren que las barreras de implementación, atribuibles a circunstancias de intermediación, de orden público y de carácter geográfico, podrían ser solventadas por nuevas tecnologías o estrategias de cribado. Es importante considerar alternativas de forma de administración y de prestación de servicios para solventar algunas barreras de aceptabilidad y acceso. Todo programa de tamización cervical debe contemplar los principios éticos de no maleficencia, beneficencia, autonomía y equidad. Futuros estudios deben enfocarse en analizar nuevas tecnologías de cribado con énfasis en población menor de 30 años. Conclusiones El uso de la prueba ADN-VPH como estrategia de tamización en mujeres menores de 30 años es una intervención probablemente efectiva y costoefectiva para Colombia. Futuros estudios deben enfocarse en analizar nuevas tecnologías de cribado con énfasis en población menor de 30 años.

Background Primary screening with Human Papilloma Virus (HPV) testing was introduced in Colombia in 2014 for individuals between 30 and 65 years of age. When the result is positive, cytology triage is performed for colposcopy referral. The convenience of initiating HPV-DNA testing for screening at 25 years of age is currently a subject of discussion. Therefore, the objective of this health technology assessment (HTA) is to analyze the available evidence regarding safety, efficacy, cost-effectiveness, values and preferences, ethical dilemmas and considerations pertaining to the implementation of the HPV-DNA test as a cervical screening strategy in women under 30 years of age in the Colombian context. Domains to be assessed Clinical efficacy and safety 1. Cumulative rate of cervical intraepithelial neoplasia (CIN) grade 2 or high-er after 2 screening rounds. 2. Cumulative rates of invasive cancer of the uterine cervix after 2 screening rounds. 3. Safety: referral to colposcopy Cost-effectiveness Cost-effectiveness for Colombia. Other domains considered Ethical considerations associated with cervical screening in women under 30 years of age. Organizational and individual considerations. Barriers and facilitators pertaining to the implementation of cervical screening in women under 30 years of age in the Colombian context. Methods Clinical efficacy and safety assessment A systematic literature search of systematic reviews and clinical trials was conducted in MEDLINE, Embase and CENTRAL. The body of evidence was rated using the GRADE approach. An interdisciplinary team was then convened to create a working group to review the retrieved evidence. This led to the discussion and construction of the conclusions following the guidelines of a formal consensus in accordance with the RAND/UCLA methodology. Economic study Systematic literature research of studies that had assessed cost-effectiveness for Colombia. Results Out of the 7,659 references retrieved, 8 studies were included. Clinical outcomes An integrative analysis of 5 randomized clinical trials that met the inclusion critera was performed. Compared with cytology, primary HPV-DNA testing in women under 30 years of age could be associated with a lower frequency of CIN+2 lesions during the first screening round (RR: 1.57; CI: 1.20 to 2.04; low evidence certainty), and a lower incidence of CIN+2 (RR: 0.67; CI: 0.48 to 0.92; low evidence certainty). Moreover, it is associated with a lower frequency of invasive carcinoma at the end of follow-up (RR: 0.19; CI: 0.07 to 0.53; high evidence certainty). Economic results From the financial point of view, the use of HPVDNA testing plus cytology-based triage starting at 25 years of age is perhaps the most cost-effective option for Colombia (incremental cost-effectiveness ratio, COP 8,820,980 in 2013). Other implications Two studies suggest that barriers to implementation attributable to intermediation, public unrest and geographic considerations could be overcome with the use of new screening technologies or strategies. It is important to consider administration and service provision alternatives in order to overcome some acceptability and access barriers. Any cervical screening program must take into consideration ethical principles of nonmaleficence, beneficence, autonomy and equity. Future studies should focus on analyzing new screening techniques with emphasis on the population under 30 years of age. Conclusions The use of HPV-DNA testing as a screening strategy in women under 30 years of age is a potentially efficacious and cost-effective intervention for Colombia. Future studies should focus on analyzing new screening technologies, with emphasis on the population under 30 years of age.

Cervical Cancer Screening with HPV Testing: Updates on the Recommendation / Rastreamento do câncer do colo de útero com teste de HPV: Atualizações na recomendação

Abstract The present update is a reassessment of the 2018 'Guidelines for HPV-DNA Testing for Cervical Cancer Screening in Brazil' (Zeferino et al.)9, according to the changes observed in new international guidelines and knowledge updates. The most relevant and recent guidelines were assessed. Questions regarding the clinical practice were formulated, and the answers considered the perspective of the public and private sectors of the Brazilian health system. The review addressed risk-based strategies regarding age to start and stop screening, the use of cytology and colposcopy to support management decisions, treatment, follow-up strategies, and screening in specific groups, including vaccinated women. The update aims to improve the prevention of cervical cancer and to reduce overtreatment and the misuse of HPV testing.

Resumo Esta atualização é uma reavaliação das "Recomendações para o uso de testes de DNAHPV no rastreamento do câncer do colo do útero no Brasil" (Zeferino et al., 2018),9 de acordo com as mudanças observadas nas novas recomendações internacionais, além das atualizações no conhecimento. As recomendações mais relevantes e recentes foram avaliadas. Questões referentes à prática clínica foram formuladas, e as respostas consideraram a perspectiva do sistema de saúde brasileiro, tanto público quanto privado. Esta revisão abrange estratégias baseadas em risco sobre idade para início e término de rastreamento, o uso da citologia e colposcopia para apoiar as condutas, tratamento, estratégias de seguimento, e rastreamento em grupos específicos, incluindo mulheres vacinadas. Esta atualização tem o objetivo de melhorar as estratégias de prevenção do câncer do colo de útero e reduzir o supertratamento e o uso incorreto dos testes de HPV.

Aceptabilidad de la autotoma como método de cribado de cáncer de cérvix en mujeres de la Región de Murcia / Acceptability of self-sampling as a method for cervical cancer screening among women from the Region of Murcia (Spain)

Fundamentos: Actualmente existe poca evidencia publicada sobre la aceptabilidad de la autotoma como prueba inicial de cribado del cáncer de cérvix en una población de mujeres que acuden a cribado regularmente. El objetivo del estudio fue determinar la aceptabilidad de la autotoma en mujeres de la Región de Murcia (RM) como prueba primaria de cribado. Métodos: Estudio transversal mediante encuesta telefónica a una muestra de 247 mujeres entre 35-65 años de la RM entre abril-mayo de 2021. Se recogieron las características sociodemográficas, los conocimientos, actitudes frente a los cribados de cáncer y valoración de la autotoma. Se realizó un análisis ponderado descriptivo, bivariante y regresión logística multivariante para determinar las características de las participantes relacionadas con su preferencia por la autotoma frente a la toma realizada por un profesional sanitario. Resultados: El 89,4% de las mujeres refirieron realizarse alguna citología en los últimos 5 años, el 88,7% de ellas con una frecuencia ≤3 años. El 81% de las mujeres prefirieron la autotoma como prueba primaria de cribado para la detección del cáncer de cérvix. No se detectaron características relacionadas con la preferencia de la autotoma frente a la toma por un profesional sanitario (P-ajustado≥0,05). Los principales inconvenientes valorados de la autotoma fueron la factibilidad (23,3%) y fiabilidad de la prueba (14,8%). Conclusiones: La aceptabilidad de la autotoma fue elevada entre las mujeres encuestadas de la RM. Sería conveniente valorar este método junto a una estrategia adecuada de educación a las mujeres dentro del programa de prevención del cáncer de cérvix.(AU)

Background: Current literature is insufficient to determine the acceptability of self-sampling as a primary method for cervical cancer screening among women from a regular screening population. The aim of this study was to determine the acceptability of selfsampling among women in the Region of Murcia as a primary screening tool. Methods: We performed a cross-sectional study between April-May 2021, in a regional sample of 247 women ages 35-65 years. All participants were contacted and completed a survey by telephone which included sociodemographic characteristics, knowledge and attitudes towards cancer screening, and self-sampling assessment. We conducted weighted statistical analysis including descriptive, bivariate and a multivariate logistic regression model to examine the associations between women’s characteristics and their preference for selfsampling compared to clinician sampling. Results: A total of 89.4% of participants reported at least one previous cytology in the last 5 years, 88.7% with a frequency equal to or less than 3 years. Eighty-ne percent of women preferred self-sampling over clinical sampling as a primary screening method. Basal characteristics were unrelated to women’s preference for self-sampling (P-adjusted≥0.05). Feasibility and reliability were the main concerns perceived in relation to self-sampling (23.3% and 14.8%, respectively). Conclusions: Acceptability of self-sampling was high among women in the Region of Murcia. Selfsampling in conjunction with an adequate educational strategy could be a suitable approach to consider in the cervical cancer screening program.(AU)

Comparative accuracy of cervical cancer screening strategies in healthy asymptomatic women: a systematic review and network meta-analysis.

To compare all available accuracy data on screening strategies for identifying cervical intraepithelial neoplasia grade ≥ 2 in healthy asymptomatic women, we performed a systematic review and network meta-analysis. MEDLINE and EMBASE were searched up to October 2020 for paired-design studies of cytology and testing for high-risk genotypes of human papillomavirus (hrHPV). The methods used included a duplicate assessment of eligibility, double extraction of quantitative data, validity assessment, random-effects network meta-analysis of test accuracy, and GRADE rating. Twenty-seven prospective studies (185,269 subjects) were included. The combination of cytology (atypical squamous cells of undetermined significance or higher grades) and hrHPV testing (excepting genotyping for HPV 16 or 18 [HPV16/18]) with the either-positive criterion (OR rule) was the most sensitive/least specific, whereas the same combination with the both-positive criterion (AND rule) was the most specific/least sensitive. Compared with standalone cytology, non-HPV16/18 hrHPV assays were more sensitive/less specific. Two algorithms proposed for primary cytological testing or primary hrHPV testing were ranked in the middle as more sensitive/less specific than standalone cytology and the AND rule combinations but more specific/less sensitive than standalone hrHPV testing and the OR rule combination. Further research is needed to assess these results in population-relevant outcomes at the program level.

Liquid-based cytology and HPV DNA test in anal specimens from women with cervical cancer.

INTRODUCTION: Cervical and anus cancers have similarities: association with HPV infection, epithelial transformation zone, and precursor lesions. However, it is still unclear whether women with cervical cancer should be screened to identify high-grade squamous intraepithelial lesions and anal cancer. We aimed to identify high-risk HPV and cytological atypia in anal samples from women diagnosed with invasive squamous cell carcinoma of the cervix. STUDY DESIGN: We conducted a cross-sectional study between July 2016 and August 2017 in reference services in oncology in the State of Ceará, Brazil. We studied 59 patients diagnosed with frankly invasive squamous cell carcinoma of the cervix (at least stages IB) and 60 women in a control group. We performed liquid-based cytology (Surepath™) and HPV test (Cobas® 4800 System Test) of anal samples. To determine statistical significance with a confidence interval of 95%, we used Fisher's exact test and Student's t-test using the GraphPad Prism 7.0 software. RESULTS: The mean age in the control group was 56.7 ± 8.5 years, while in the group of women with cervical squamous cancer, it was 54.3 ± 14.8. The liquid-based cytology results of the satisfactory cases were: negative for intraepithelial lesion or malignancy (NLM): 51 cases (85%) in the control group and 38 (64.4%) in the study group (p = .0116). The HPV test was negative more frequently in the control group (n = 56, 93.3%) than in the study group (n = 17, 31.5%) (p < .0001). HPV 16 was the most frequent type (67.6%). CONCLUSIONS: There is a higher frequency of high-risk HPV and atypical cytology in women with cervical cancer than without lesions. Thus, this group should be considered as a target population for screening.

Accuracy of different triage strategies for human papillomavirus positivity in an Italian screening population.

How to manage human papillomavirus (HPV)-positive women in cervical cancer screening remains debated. Our study compared different strategies to triage HPV positivity in a large cohort of women participating in a population HPV-based screening program. Women were tested for HPV (Cobas 4800; Roche), and those positive were triaged with cytology; cytology-positives were referred to colposcopy, while negatives were referred to 1-year HPV retesting. All HPV-positive women were also evaluated with p16/ki67 dual staining (Roche). All lesions found within 24 months of follow-up were included in the analyses. Of the 70 146 women tested, 4757 (6.8%) were HPV-positive. Of these, 1090 were cytology-positive and were referred to colposcopy. Of the 2958 HPV-positive/cytology-negative women who presented at 1-year retesting, 1752 (59.9%) still tested positive. Cumulatively, 532 CIN2+ (including 294 CIN3+) were found. The sensitivity of cytology, HPV16/18 and p16/ki67 as triage test for CIN3+ was 67.9%, 56.0% and 85.0%, respectively. The positive predictive value (PPV) for immediate colposcopy referral was 21.0%, 15.8% and 22.9%, respectively. Combining cytology with typing increased sensitivity to 83.9% and lowered PPV to 14.8%, while combining p16/ki67 and typing increased sensitivity to 91.1%, lowering the PPV to 15.9%. Women negative to p16/ki67 triage presented a cumulative 1-year CIN3+ risk of about 1%. In conclusion, when triaging HPV positivity, p16/ki67 performed better than cytology with or without HPV16/18 genotyping. The strategies that included dual staining achieved sensitivity and low 1-year risk for CIN3+ sufficiently high enough to permit considering extending the surveillance interval to 2 to 3 years for HPV-positive/triage-negative women.

Rastreamento do câncer do colo do útero com teste de DNA-HPV: atualizações na recomendação / Cervical cancer screening with DNA-HPV testing: updates on the recommendation

Esta é uma atualização da recomendação de especialistas publicada em 2018 para o uso do teste de detecção do DNA-HPV de alto risco no rastreamento do câncer do colo do útero no Brasil, de acordo com as mudanças observadas nas diretrizes internacionais e atualizações do conhecimento. As recomendações mais relevantes e recentes foram revisadas. Questões referentes à prática clínica foram formuladas, e as respostas consideraram a perspectiva do sistema de saúde brasileiro, tanto público quanto privado. Essa revisão abrange estratégias baseadas em risco sobre idade para início e término de rastreamento, o uso da citologia e colposcopia para apoiar as condutas, tratamento, estratégias de seguimento, e rastreamento em grupos específicos, incluindo mulheres vacinadas. O objetivo é melhorar as estratégias de prevenção do câncer do colo do útero e reduzir o supertratamento e o uso incorreto dos testes de HPV.(AU)

Neoplasia intraepitelial escamosa cervical: abordagem por estimativas de risco / Cervical squamous intraepithelial neoplasia: risk estimation approach

As neoplasias intraepiteliais cervicais representam a fase pré-tumoral da neoplasia invasiva do colo uterino; são identificadas por citologia e testes de DNA-HPV e conduzidas por intervenções ambulatoriais. A perspectiva de estimativas de risco, para abordagem de tais lesões, constitui uma verdadeira mudança de paradigma, tendo em vista que as recomendações serão baseadas em riscos, não em resultados.(AU)

Cervical intraepithelial neoplasms represent the pre-tumor phase of invasive cervical cancer; identified by cytology, HPV-DNA testing and conducted by outpatient interventions. The perspective of risk estimates, to address such injuries, constitutes a true paradigm shift, considering that recomendations will be based on risks, not results.(AU)

Histerectomia radical após parto cesáreo por adenocarcinoma de colo uterino: relato de caso / Radical hysterectomy after c-section in cervical adenocarcinoma: a case report

Mundialmente, o câncer de colo uterino ocupa o quarto lugar das neoplasias em mulheres, porém, nos países em desenvolvimento, as taxas de incidência superam de forma impactante os casos de países desenvolvidos. Apesar de ser um evento incomum durante a gestação, é cada vez mais observado, o que talvez possa ser atribuído às gestações programadas em idades mais avançadas. O caso descrito refere-se a uma paciente de 32 anos de idade, diagnosticada no terceiro trimestre da gestação com adenocarcinoma de origem endocervical com estadiamento anatomopatológico final (FIGO 2018) 1B2. Ela foi submetida à abordagem cirúrgica como tratamento inicial. Foi adotada como conduta a resolução da gestação, com boa vitalidade fetal, ao final da 34ª semana, após corticoterapia para maturação pulmonar fetal. Foi realizado parto cesariano seguido de histerectomia radical tipo C1 na classificação de Querleu e Morrow associado a linfadenectomia pélvica, no mesmo ato operatório.(AU)

Worldwide, cervical cancer ranks fourth in female cancers, but when assessing data from developing countries, incidence rates are significantly higher than in developed countries. Although it is an uncommon event during pregnancy, it is increasingly observed, which may perhaps be justified due to pregnancies postponed at older ages. The case described relates to a 32-year-old woman diagnosed in the third trimester of pregnancy with endocervical adenocarcinoma, whose final anatomopathological staging (FIGO 2018) was IB2. The same was submitted to the surgical approach as an initial treatment. It was adopted as a conduct, the resolution of pregnancy, with good fetal viability, at the end of the 34th week, after corticosteroid therapy for fetal lung maturation. The patient underwent cesarean section followed by radical type C1 hysterectomy in the classification of Querleu and Morrow associated with pelvic lymphadenectomy in the same surgery.(AU)
