Cervical Intraepithelial Neoplasia grade 2 biopsy: Do p16INK4a and Ki-67 biomarkers contribute to the decision to treat? A cross-sectional study

ABSTRACT BACKGROUND: Managing cervical intraepithelial neoplasia grade 2 (CIN2) is challenging, considering the CIN2 regression rate, perinatal risks associated with excisional procedures, and insufficient well-established risk factors to predict progression. OBJECTIVES: To determine the ability of p16INK4a and Ki-67 staining in biopsies diagnosed with CIN2 to identify patients with higher-grade lesions (CIN3 or carcinoma). DESIGN AND SETTING: Cross-sectional study conducted at a referral center for treating uterine cervical lesions. METHODS: In 79 women, we analyzed the correlation of p16INK4a and Ki-67 expression in CIN2 biopsies with the presence of a higher-grade lesions, as determined via histopathology in surgical specimens from treated women or via two colposcopies and two cytological tests during follow-up for untreated women with at least a 6-month interval. The expression of these two biomarkers was verified by at least two independent pathologists and quantified using digital algorithms. RESULTS: Thirteen (16.8%) women with CIN2 biopsy exhibited higher-grade lesions on the surgical excision specimen or during follow-up. p16INK4a expression positively and negatively predicted the presence of higher-grade lesions in 17.19% and 86.67% patients, respectively. Ki-67 expression positively and negatively predicted the presence of higher-grade lesions in 40% and 88.24% patients, respectively. CONCLUSIONS: Negative p16INK4a and Ki67 immunohistochemical staining can assure absence of a higher-grade lesion in more than 85% of patients with CIN2 biopsies and can be used to prevent overtreatment of these patients. Positive IHC staining for p16INK4a and Ki-67 did not predict CIN3 in patients with CIN2 biopsies.

Efectividad de la crioterapia suministrada por enfermeras para lesiones preneoplásicas del cuello uterino

Introducción. El cáncer de cuello uterino es un problema de salud pública relevante en países de ingresos medios y bajos. El seguimiento de mujeres con tamización positiva y el acceso a tratamiento para neoplasia intraepitelial cervical (NIC) son retos mayores en estos países. Objetivo. Evaluar la efectividad de la crioterapia suministrada por enfermeras en casos de neoplasia intraepitelial de cérvix. Materiales y métodos. Se hizo la inspección visual directa con ácido acético y solución yodada (VIA-VILI), y se practicó colposcopia con biopsia, a mujeres entre los 25 y los 59 años, residentes en zonas de bajos ingresos de Bogotá. Profesionales de enfermería entrenados ofrecieron tratamiento inmediato con crioterapia a mujeres positivas en la inspección visual. Se les practicó colposcopia con biopsia antes del tratamiento y en un control a los 12 meses. Se evaluó la efectividad mediante tasas de curación (resultado: sin lesión) y regresión de NIC2/3 (resultado: ≤NIC1), por verificación colposcópica e histológica. Resultados. Se tamizaron 4.957 mujeres. En total, 499 fueron positivas y 472 aceptaron el tratamiento inmediato. Recibieron crioterapia por enfermería 365 mujeres (11 NIC2/3). La tasa de curación fue del 72 % (IC95%: 39-94 %) por verificación colposcópica, y del 40 % (IC95%: 22-85 %) por histología. Las tasas de regresión fueron del 100 y el 60 %, respectivamente. Se reportaron dos eventos adversos no graves relacionados. Conclusiones. Las tasas de curación y regresión por verificación colposcópica son similares a las reportadas con crioterapia administrada por médicos. El tamaño de la muestra con NIC2/3 dificulta la comparación por tipo de verificación. Los hallazgos apoyan la implementación de estrategias de "ver y tratar" por parte de enfermería en poblaciones con acceso limitado a servicios de salud.

Introduction. Cervical cancer is a relevant public health problem for low- and middleincome countries. Follow-up of positive-screened women and compliance with treatment of precancerous lesions are major challenges for these settings. Objective. To evaluate the efficacy of cryotherapy delivered by nurses for cervical intraepithelial neoplasia (CIN). Materials and methods. Direct visual inspection with acetic acid and lugol iodine (VIA- VILI), and colposcopy/biopsy were performed on women 25 to 59 years old, residents of low-income areas in Bogotá, Colombia. Trained nurses offered immediate cryotherapy to every woman with positive visual inspection. Colposcopy/biopsy was performed before treatment and at a 12-month follow-up. The effectiveness was measured as cure (outcome: no-lesion) and regression (outcome: CIN1) rates of CIN2/3 using colposcopic and histological verification. Results. A group of 4.957 women with VIA/VILI was valuated. In total, 499 were screen positive and 472 accepted immediate treatment. A total of 365 women (11 CIN2/3) received cryotherapy by nurses. Cure rate was 72% (95%CI: 39%-94%) and 40% (95%CI: 22%- 85%) by colposcopic and histological verification, respectively. Regression rates were 100% and 60%. There were two related non-serious adverse events. Conclusions. Cure and regression rates by colposcopic verification are like those reported for cryotherapy delivered by doctors. The sample size (CIN2/3) hinders comparisons by type of verification. Our findings support the implementation of screen-and-treat algorithms by nurses among populations with limited access to health services.

Comparación del Papanicolau con técnica convencional frente a técnica modificada / Comparison of the Pap smear with conventional technique versus modified technique

Introducción: a pesar de que la técnica de papanicolaou es el método más eficaz para la prevención y detección del cáncer cervicouterino, la precisión de esta herramienta sigue siendo controversial; debido a esto, existen esfuerzos médicos y científicos para mejorar la calidad del procedimiento. Objetivo: comparar la calidad en la toma de muestra entre la técnica convencional y la modificada. Material y métodos: estudio observacional descriptivo y comparativo en 150 muestras de citología cervical (75 muestras técnica convencional y 75 en técnica modificada) en mujeres de 25 a 64 años. Se analizaron variables emográficas, características del cérvix y calidad de la muestra. Se realizó estadística descriptiva y medidas de asociación. Estudio con riesgo mayor que el mínimo. Todas las participantes firmaron consentimiento informado. Resultados: la calidad de la muestra fue satisfactoria en el 92% para la técnica convencional frente al 89.3% para la técnica modificada. La causa principal de muestras insatisfactorias fue la celularidad insuficiente, la cual se presentó en el 6.7% de las muestras con técnica convencional frente al 12% de la técnica modificada, sin diferencia significativa entre ambas técnicas p = 0.575 (1.37; 0.45-4.1), hallazgos que rechazan la hipótesis de trabajo. Conclusiones: no hubo diferencia significativa al utilizar ambas pruebas, las muestras con calidad satisfactoria fueron similares entre ambas técnicas.

Background: Despite the fact that the Papanicolaou technique is the most effective method of prevention and detection of cervical cancer, the precision of this tool remains controversial; Because of this, there are medical and scientific efforts to improve the quality of the procedure. Objective: Compare the quality of sampling between the conventional and modified technique. Material and methods: Descriptive and comparative observational study in 150 cervical cytology samples (75 conventional technique samples and 75 in modified technique) in women aged 25 to 64 years. Demographic variables, characteristics of the cervix and quality of the sample were analyzed. Descriptive statistics and association measures were performed. Study with risk greater than the minimum. All participants signed an informed consent. Results: The quality of the sample was satisfactory in 92.0% for the conventional technique vs 89.3% for the modified technique.

El 68,8 % de las infecciones por VPH-AR en el canal anal correspondió a genotipos de VPH-AR diferentes a 16 o 18. Conclusiones: La prevalencia de infección anal por VPH-AR en mujeres con displasia cervical fue del 32 %. Es importante determinar la utilidad del tamizaje del compromiso de la mucosa anal por virus VPH de alto riesgo de cáncer en mujeres con displasia cervical. Se requieren estudios sobre el pronóstico de la infección anal por VPH-AR en las mujeres con displasia cervical.

ABSTRACT Objective: To determine the prevalence of anal infection caused by high risk human papilloma virus (HR-HPV) and of abnormal anal cytology in women with confirmed cervical dysplasia. Materials and methods: Cross sectional study that included patients between 30 and 65 years of age with a new diagnosis of cervical dysplasia by histopathology attended in two lower genital tract colposcopy and pathology units (one public and one private institution), conducted between December 2017 and April 2019. Women with human immunodeficiency virus (HIV) infection, immune compromise (use of steroids, transplant, chemo therapy), pregnancy or anorectal malformations were excluded. Consecutive sampling. Socio demographic variables, intercourse type, degree of cervical dysplasia, positive results of HR HPV Polymerase Chain Reaction test in anal canal and HR - HPV type indentified (16-18 or others) were evaluated. Descriptive statistics were used. Results: Of 188 candidates, 100 were included in the analysis. A 32 % prevalence of high-risk HPV infection and a 2.8 % prevalence of abnormal cytology in the anal canal (ASCUS) were found. Of the HR-HPV infections in the anal canal, 68.8 % corresponded to HR-HPV genotypes different from 16 or 18. Conclusions: Prevalence of HR HPV infection in women with lower genital tract dysplasia was 32%. It is important to determine the usefulness of screening for anal mucosa compromise by HPV virus associated with a high risk of cancer in women with cervical dysplasia. Studies are needed on the prognosis of anal HR-HPV infection in women with cervical dysplasia.

Prevalencia de los Genotipos del Virus del Papiloma Humano en mujeres de 25 a 65 años / Prevalence of Human Papillomavirus Genotypes in women aged 25 to 65 years

Introducción: La infección que ocasiona el Virus del Papiloma Humano (VPH), tiene alta prevalencia en mujeres sexualmente activas. Generalmente es pasajera, pero al existir algunos factores relacionados pueden llegar a desarrollar cáncer cervicouterino. Dado que la enfermedad se desarrolla con lentitud la detección en etapas tempranas ha permitido poner en evidencia la presencia del virus en las células antes que puedan transformarse y volverse tumorigénicas. El objetivo de este estudio fue establecer la prevalencia de los genotipos del Virus del Papiloma Humano en mujeres de 25 a 65 años en un grupo de pacientes de un centro oncológico en Cuenca 2017 ­2018. Métodos:Es un estudio descriptivo, retrospectivo, analítico, en el cual se recopiló información de las historias clínicas y registros físicos del Laboratorio de Biología Molecular y del sistema médico de SOLCA -Cuenca, SOFTCASE, para establecer la prevalencia de VPH durante el periodo 2017 -2018.Se utiliza ODDS Ratio para demostrar asociación entre las variables demográficas y los grupos de serología de VPH de riesgo alto versus VPH De riesgo bajo. Resultados:Se incluyeron 594casos, con edad entre36 y 40 años n=103/594 (17.3%). De estado civil casadas n=318/594 (53.5%). Con paridad igual a 2 n=159/594 (26.8%). Casospositivos de VPH fueron 424/594 (71.38%) IC95% (71.23% a 71.53%), Genotipos de alto riesgo con el 58.01%, genotipos de probable bajo riesgo con el 33.25% y genotipos de bajo riesgo 8.72%. La prevalencia del 50% de la población positiva según el genotipo lo explicalos VPH 16, 71, 58, 6 y 31. De este grupo los VPH con serología 16, 58 y 31 tienen un riesgo Alto de malignidad. No se reportó asociación entre los VPH de alto riesgo con alguna de las variables demográficas. Conclusión:El grupo etario con mayor número de casos positivos perteneció a las mujeres de entre 36 y 40 años de edad, con paridad igual a 2 y de estado civil casadas. El subtipo VPH-16 fue el genotipo más prevalente del grupo de alto riesgo de malignidad. El subtipo VPH-71 fue el segundo genotipo más prevalente con un perfil de probable bajo riesgo de malignidad.

AbstractIntroduction:The infection caused by the Human Papilloma Virus (HPV) has a high prevalence in sexually active women. It is generally temporary, but when there are some related factors, they can develop cervical cancer. Since the disease develops slowly, detection in early stages has made it possible to reveal the presence of the virus in cells before they can transform and become tumorigenic. The objective of this study was to establish the prevalence of Human Papilloma Virus genotypes in women aged 25 to 65 years in a group of patients from an oncology center in Cuenca 2017-2018. Methods: It is a descriptive, retrospective, analytical study, in which information was collected from the medical records and physical records of the Molecular Biology Laboratory and the SOLCA -Cuenca medical system, SOFTCASE, to establish the prevalence of HPV during the period 2017 -2018. ODDS Ratio is used to demonstrate association between demographic variables and high-risk HPV versus low-risk HPV serology groups. Results: 594 cases were included, aged between 36 and 40 years, n = 103/594 (17.3%). Marital status married n = 318/594 (53.5%). With parity equal to 2 n = 159/594 (26.8%). Positive HPV cases were 424/594 (71.38%) 95% CI (71.23% to 71.53%), high risk genotypes with 58.01%, probable low risk genotypes with 33.25% and low risk genotypes 8.72%. The prevalence of 50% of the positive population according to genotype is explained by HPV 16, 71, 58, 6 and 31. Of this group, HPV with serology 16, 58 and 31 have a high risk of malignancy. No association was reported between high-risk HPV with any of the demographic variables. Conclusion: The age group with the highest number of positive cases belonged to women between 36 and 40 years of age, with parity equal to 2 and married marital status. The HPV-16 subtype was the most prevalent genotype in the group at high risk of malignancy. The HPV-71 subtype was the second most prevalent genotype with a profile of probable low risk of malignancy.

Human Papilloma Virus genotypes in Type III cervical intraepithelial neoplasia. Cuenca­Ecuador, 2013-2017 / Genotipos del virus del papiloma humano en neoplasias intraepiteliales tipo III; Cuenca-Ecuador, 2013-2017

Cervical cancer is one of the most common cancers in female population worldwide in underdeveloped countries, and in Ecuador it stands out in second place. This research focuses on HPV-genotype description in type III-intraepithelial neoplasms. The study type was analytical, retrospective and cross-sectional. The sample was 195 patients with NIC III diagnosis, from 20 to 60 years old, who were in the data system of "Sociedad de Lucha Contra el Cancer" Cuenca­Ecuador, 2013-2017 term. It was established that HPV-16 genotype was in 32.9% (n 51) of all cases; factors like sociodemographic variables, tobacco use, infection, hormonal contraceptives use, more than one sexual partner, age of start of active sex life equal or less than 20 years old, didn´t show a relationship with HPV infection; on the other hand, IUD use and HPV-16 infection had a statically significant relationship (OR 2,75; CI 95% 1,21-6,26; p 0,01). HPV genotype HPV-16 was the most common, and IUD use was a risk factor to get HPV infection

El cáncer de cuello uterino, es uno de los cánceres más frecuentes en la población femenina a nivel mundial en países subdesarrollados, y en Ecuador ocupa el segundo lugar. Esta investigación se sitúa en la descripción de los genotipos del VPH en neoplasias intraepiteliales tipo III. El tipo de estudio fue analítico, retrospectivo y transversal. La muestra fueron 195 pacientes con diagnóstico de NIC III, de 20 hasta los 60 años de edad, que se encontraba en el sistema informático de la "Sociedad de Lucha Contra el Cáncer", Cuenca ­ Ecuador, periodo 2013 - 2017. Los datos fueron procesados a través del software SPSS 23.00. Se determinó que el genotipo VPH-16 estuvo en el 32,9% (n 51) de los casos; las variables sociodemográficas, consumo de tabaco, infecciones, uso de anticonceptivos hormonales, más de una pareja sexual, IVSA igual o menor de 20 años no presentaron relación a la infección por VPH; pero, el uso de DIU e infección por VPH-16 tuvo una relación estadísticamente significativa (OR 2,75; IC 95% 1,21-6,26; p 0,01). El genotipo de VPH-16 fue el más frecuente, y el uso de DIU fue un factor de riesgo para adquirir la infección por el VPH

Intraepithelial cervical lesions in indigenous in Ecuador / Lesiones intraepiteliales cervicales en indígenas del Ecuador

The aim of this research was to determine the prevalence of cervical intraepithelial lesions in indigenous women of Ecuador 2017. A descriptive study was performed. Population was formed by 2489 indigenous women aged 15 to 64 years old, of which 396 users were chosen by spontaneous demand. Frequency values and percentages were taken from qualitative variables, while mean and standard deviation were taken from quantitative variables. Prevalence of intraepithelial lesions was 13,8%. Average age was 31 years old. Uncertain importance's squamous atypical cells were higher in 30-to-39-year-old group (46,7%). Non-specific atypical glandular cells were observed in 66,7% of 30-to-39-year-old group. Low-grade intraepithelial lesions were majorly found in 20-to-29-year-old group (43,8%). High-grade intraepithelial lesions were also seen in 20-to-29-year-old group. Conclusions were: prevalence of intraepithelial lesions in indigenous women of Ecuador was higher than 10% of reported in other studies, and more frequent in those aged 20 and 39 years old

Cytomorphological analysis of cervical cytological smears of women aged over 60 years / Análise citomorfológica de esfregaços citológicos cervicais de mulheres com idade superior a 60 anos

ABSTRACT Introduction: Cervicovaginal atrophy is a condition that can affect women after menopause, and cytology is a diagnostic tool useful in such cases. Objective: To evaluate the cytomorphological profile of cervical smears in patients over 60 years old. Methods: Cytopathological examinations of 500 patients over 60 years old were selected consecutively in this cross-sectional, quantitative, retrospective study. Results: Only 114 (22.8%) presented the squamocolumnar junction (SCJ) sampled, and their presence decreased progressively with advancing age (p < 0.001). Most smears (95.6%) were classified as atrophic. Microbiological analysis showed that from the 22 non-atrophic smears, most presented lactobacillus flora. Among the atrophic swabs, the predominant flora was cocci, with 47.2%. Only 4% presented cytological changes: atypical squamous cells of undetermined significance [(ASC-US) - eight cases/40%], atypical squamous cells - cannot exclude high-grade squamous intraepithelial lesion [(ASC-H) - five cases/25%], high-grade squamous intraepithelial lesion [(HSIL) - three/15%], low-grade squamous intraepithelial lesion [(LSIL) - two cases/10%] and adenocarcinoma in situ [(ACI) - two cases/10%]. Among the modified smears, four (20%) presented SCJ cells, and four patients (20%) took hormones (from these, two cases of ASC-H (10%) and two cases ASC-US (10%), showing a relationship between the onset of the lesion and the use of hormones (p < 0.05). Conclusion: The absence of SCJ indicates a diagnostic limitation of sample collection. Although the frequency of lesions has been similar to other studies, and the recommended age range for the examination is between 25 and 60 years, it is important to note that many women older than this range should perform the collection of oncology cytology due to existence of elderly women with risk profile for the disease.

RESUMEN Introducción: La atrofia cervicovaginal es una condición que puede afectar a las mujeres después de la menopausia, y la citología es una herramienta diagnóstica útil en esos casos. Objetivo: Evaluar el perfil citomorfológico de frotis citopatológicos cervicales en pacientes mayores de 60 años. Métodos: Un estudio transversal, cuantitativo y retrospectivo, en el que se eligieron consecutivamente pruebas citopatológicas de 500 pacientes con edad superior a 60 años. Resultados: Solo 114 mujeres (22,8%) tuvieron la unión escamo-columnar (UEC) representada; su presencia ha bajado progresivamente con el adelanto de la edad (p < 0,001). Los frotis (95,6%), en su mayoría, fueron clasificados como atróficos. El análisis microbiológico mostró que de los 22 frotis no atróficos, la mayoría tuvo flora lactobacilar. Entre los frotis atróficos, la flora predominante fue cocoide (47,2%). Solamente 4% presentó alteraciones citológicas: células escamosas atípicas de importancia no determinada [(ASC-US) - ocho casos/40%]; células escamosas atípicas, no se descarta una lesión de alto grado [(ASC-H) - cinco casos/25%]; lesión intraepitelial de alto grado [(HSIL) - três casos/15%]; lesión intraepitelial escamosa de bajo grado [(LSIL) - dos casos/10%] y adenocarcinoma in situ [(ACI) - dos casos/10%]. Entre los frotis alterados, cuatro (20%) contenían células de la UEC y cuatro pacientes (20%) estaban recibiendo hormonas [entre ellos, dos casos de ASC-H (10%) y dos casos de ASC-US (10%)]. Conclusión: La ausencia de UEC indica la limitación diagnóstica de la recolección. Aunque la frecuencia de las lesiones haya sido semejante a la de otros trabajos y la franja etaria recomendada para la realización de la prueba sea 25-60 años, es importante señalar que mujeres con edad superior a esa franja deben realizar la recolección citológica debido al perfil de riesgo para la enfermedad.

RESUMO Introdução: A atrofia cervicovaginal é uma condição que pode afetar mulheres após a menopausa, e a citologia é a ferramenta diagnóstica útil nesses casos. Objetivo: Avaliar o perfil citomorfológico de esfregaços citopatológicos cervicais de pacientes com idade superior a 60 anos. Métodos: Trata-se de estudo transversal, quantitativo e retrospectivo, no qual foram selecionados consecutivamente exames citopatológicos de 500 pacientes com idade superior a 60 anos. Resultados: Apenas 114 mulheres (22,8%) tiveram a junção escamocolunar (JEC) representada e sua presença diminuiu progressivamente com o avanço da idade (p < 0,001). Os esfregaços (95,6%), em sua maioria, foram classificados como atróficos. A análise microbiológica mostrou que dos 22 esfregaços não atróficos, a maioria teve flora lactobacilar. Entre os esfregaços atróficos, a flora predominante foi cocoide (47,2%). Somente 4% apresentou alterações citológicas: células escamosas atípicas de significado indeterminado [(ASC-US) - oito casos/40%], células escamosas atípicas, não podendo excluir lesão intraepitelial de alto grau [(ASC-H) - cinco casos/25%], lesão intraepitelial escamosa de alto grau [(HSIL) - três casos/15%], lesão intraepitelial escamosa de baixo grau [(LSIL) - dois casos/10%] e adenocarcinoma in situ [(ACI) - dois casos/10%]. Entre os esfregaços alterados, quatro (20%) continham células da JEC e quatro pacientes (20%) faziam uso de hormônios [destes, dois casos de ASC-H (10%) e dois casos ASC-US (10%)], o que demonstra a relação entre o aparecimento de lesão e o uso de hormônios (p < 0,05). Conclusão: A ausência da JEC indica a limitação diagnóstica da coleta. Embora a frequência das lesões tenha sido semelhante à de outros trabalhos e a faixa etária recomendada para a realização do exame seja entre 25 e 60 anos, é importante ressaltar que mulheres com idade superior a essa faixa devem realizar a coleta de citologia oncológica devido ao perfil de risco para a doença.

Risk of cervical dysplasia among human papillomavirus-infected women in Korea: a multicenter prospective study / 부인종양

OBJECTIVE: Human papillomavirus (HPV) infection is the most important risk factor for cervical cancer, which progresses from precursor lesions with no symptom if left untreated. We compared the risk of cervical dysplasia among HPV-positive Korean women based on HPV types and infection patterns. METHODS: We observed participants of a 5-year multicenter prospective cohort study, comprising HPV-positive women with either atypical squamous cells of undetermined significance or low-grade squamous intraepithelial lesion of the cervix at their enrollment. Follow-ups, comprising cytology and HPV DNA testing results, were included in the final analysis. Incidence was calculated for each infection pattern (persistent infection, incidental infection, and clearance). To investigate cervical dysplasia risk, we used Cox proportional hazard models adjusted for variables that were significantly different among infection patterns. From April 2010 to September 2017, 71 of 1,027 subjects developed cervical dysplasia more severe than high-grade squamous intraepithelial lesion of the cervix. RESULTS: Of these 71 subjects, persistent infection, incidental infection, and clearance were noted in 30, 39, and 2 individuals, respectively. Based on changes in DNA results during follow-up, cumulative incidence was 27.2%, 10.4%, and 0.5% for persistent infection, incidental infection, and clearance, respectively. Compared to clearance, the adjusted hazard ratios for cervical dysplasia were 51.6 and 24.1 for persistent and incidental infections, respectively (p < 0.001). CONCLUSION: Individuals persistently infected with the same HPV types during the follow-up period had the highest risk of severe cervical dysplasia. Hence, it is necessary to monitor HPV types and infection patterns to prevent severe cervical precancerous lesions.

Prevalência da infecção pelo Papilomavírus Humano (HPV) em mulheres do sudeste do Estado do Pará / Prevalence of human Papillomavirus Infection (HPV) in females from the southeastern region of the State of Pará, Brazil

Investigar a prevalência da infecção pelo Papilomavirus humano (HPV) em mulheres do município de Jacundá (PA) e fatores de risco para esta infecção. Estudo observacional, descritivo e analítico, do tipo transversal com coleta em prontuários de mulheres atendidas no Hospital Municipal e consultório particular de ginecologia, oriundos de Jacundá entre 2015 e 2016. Aplicou-se análise descritiva pelo programa Epi Info 3.5.1 e BioEstat 5.0. Dos 235 prontuários, 36,6% possuíam HPV e aquelas com 45 anos ou mais possuíam maior prevalência desta infecção (40,3%). Quanto à citologia, 28,9% possuíam alguma alteração. E somente as variáveis escolaridade, etilismo e citologia alterada possuíam associação significante, exclusivamente para as de 26 a 44 anos, sendo variáveis consideradas como fatores de risco para aquisição e manutenção viral. Assim, houve alta prevalência de HPV na região (45 anos ou mais) com fatores de risco relacionados à escolaridade, ao etilismo e às alterações na citologia cervical, na faixa etária de 26 a 44 anos.

The prevalence of infection by human papillomavirus (HPV) in females of Jacundá PA Brazil and its risk factors are discussed. Current observational, descriptive, analytic and transversal study of clinical charts of females from the municipality of Jacundá and attended to in the Municipal Hospital and private clinic was undertaken between 2015 and 2016. Descriptive analysis was applied by programs Epi Info 3.5.1 and BioEstat 5.0. Further, 36.6% of people in 235 charts had HPV; females aged 45 years or more had the greatest prevalence (40.3%) of the infection; 28.9% had alterations in cytology. Variables such as schooling, alcoholism and altered cytology had significant association, exclusively for people between 26 and 44 years old. They are variables considered to be risk factors for the acquisition and maintenance of the virus. High prevalence of HPV occurred in the region (with 45 years old and older) with risk factors related to schooling, alcoholism and cervix cytology changes in the 26-44 years age bracket.

Clinical significance of HPV E6/E7 mRNA test combining TCT test to detect early cervical dysplasia / 实用医学杂志

Objective To investigate the value of HPV E6/E7 mRNA test combining liquid-based cytology test in cervical cancer screening. Methods A total of 377 samples from Wenzhou People's Hospital from June 2014 to September 2015 were collected and screened by HPV E6/E7 mRNA test combining with liquid-based cytology test , and the results was compared with the findings from the gold criteria of histology and pathology. Results The combination of HPV E6/E7 mRNA test and liquid-based cytology test can enhance the testing sensitivity and specificity. The sensitivity of the combination of HPV E6/E7 mRNA test and liquid-based cytology test for the diagnosis of LSIL was 94.41%, and that for the diagnosis of HSIL was 96.36%. Based on the gold criteria of histology and pathology , the sensitivity , specificity , positive-predictive value and negative predictive value of HPV E6/E7 mRNA test for the diagnosis of HSIL was 90%, 60.67%, 48.53% and 92.49%respectively. The sensitivity, specificity, positive-predictive value and negative- predictive value of liquid-based cytology test for the diagnosis of HSIL was 72.73%, 75.28%, 54.79% and 87.01% respectively. Conclusions The sensitivity of HPV E6/E7 mRNA test is superior to that of liquid-based cytology test , while the specificity of HPV E6/E7 mRNA test is inferior to that of liquid-based cytology test. The negative predictive value of HPV E6/E7 mRNA test is more meaningful than that of liquid-based cytology test. The combination of HPV E6/E7 mRNA test and liquid-based cytology test can enhance the testing sensitivity , but it does not increase the specificity.

P16INK4a: A Potential Diagnostic Adjunct For Prediction Of Highgrade Cervical Lesions In Liquid-Based Cytology: With HPV Testing And Histological Correlation

Human papillomavirus (HPV) is a necessary cause of cervical cancer and its precursors. Increased expression of high-risk hrHPV viral oncogenes in abnormal cells might increase the expression of p16INK4a. We aimed to determine the role of p16INK4a in detecting hrHPV-transformed epithelial cells in liquid-based cervical cytology, and compared the results with hrHPV DNA testing by realtime polymerase chain reaction (RT-PCR). Fifty-seven cytological samples were tested for p16INK4a immunomarker and hrHPV DNA. Test performance of both tests was determined by comparing sensitivity, specificity and predictive values using available histological follow-up data as gold standard. Of 57 samples, 36 (63.2%) showed immunoreactivity for p16INK4a and 43 (75.4%) were hrHPV-infected. A fairly low concordance rate (k = 0.504) between p16INK4a immunolabelling and hrHPV DNA status was noted. For prediction of cervical intraepithelial neoplasia (CIN) II and worse lesions, p16INK4a had a sensitivity and specificity of 93.5% and 60%; whereas hrHPV DNA testing had a sensitivity and specificity of 100% and 20%. Dual testing by combining p16INK4a and hrHPV showed sensitivity and specificity of 100% and 33.3%. In conclusion, p16INK4a is useful in predicting severity of the cytological abnormalities. Although p16INK4a is more specific but less sensitive than hrHPV in detecting high-grade cervical lesions, a combination of both tests failed to demonstrate significant improvement in diagnostic sensitivity, specificity and predictive value. Larger-scale prospective studies are required to assess further whether this biomarker should be routinely used as primary screening tool independently or in combination with hrHPV testing to improve diagnostic accuracy in cervical cytology.

Clinical management of the first ASCUS report in Chile. Prospective single-cohort study / Manejo clínico do primeiro relatório ASCUS no Chile. Estudo prospectivo de coorte única

ABSTRACT CONTEXT AND OBJECTIVE: Worldwide, there is no single strategy for optimal management of patients with ASCUS (atypical squamous cells of undetermined significance) cytology reports. The objective of this study was to determine the kind of clinical management conducted among women with a first ASCUS Pap smear report. DESIGN AND SETTING: Prospective single cohort study at a cervical pathology unit in Santiago, Chile. METHODS: This was an epidemiological, descriptive, observational and quantitative follow-up study on a cohort of women with ASCUS cytological reports. RESULTS: In the screening phase, 92,001 cervical cytological smears were collected in primary healthcare clinics. In the diagnostic phase, all women with a first ASCUS report were selected (n = 446). These women were asked to undergo the Pap test again and it was found that 301 women had normal results, 62 women had abnormal results and 83 did not repeat the test. In the diagnostic confirmation phase, the 62 women with abnormal results underwent colposcopy and, from these results, 58 of them underwent a biopsy. The results from the biopsies showed that 16 women had negative histological reports, 13 had CIN 1 and 29 had CIN 2+. In the treatment phase, the 42 women with lesions underwent a variety of treatments, according to the type of lesion. In the post-treatment phase, cytological and colposcopic monitoring was instituted. CONCLUSION: The clinical management consisted of traditional management of screening, diagnosis, diagnostic confirmation, treatment and post-treatment monitoring.

Histopathology was required in 230 cases (65%) and the prevalence among them of HSIL was 26.5%. Conclusions: The results of this study showed a prevalence of 1.49% for ASC-H. Given that an important number of patients have a high-grade intraepithelial lesion, colposcopy-guided biopsy is recommended in patients with this result...

Impact of age on the false negative rate of human papillomavirus DNA test in patients with atypical squamous cells of undetermined significance

OBJECTIVE: Human papillomavirus (HPV) test was incorporated into the triage of lesser abnormal cervical cytologies: atypical squamous cells of undetermined significance (ASCUS) or low-grade squamous intraepithelial lesion (LSIL). This study aimed to evaluate the impact of age on the efficacy of HPV testing in patients with lesser abnormal cervical cytologies. METHODS: A total of 439 patients with ASCUS or LSIL were included. The association between age groups and the diagnostic performances of HPV test for high-grade cervical intraepithelial neoplasia (CIN2+) was evaluated. RESULTS: Median age was 44 years (range, 17 to 75 years). ASCUS was more frequently observed in older patients while LSIL was more common in younger patients (P=0.002). CIN2+ was found in 11.3% (32/284) of the ASCUS patients and 12.9% (20/155) of patients with LSIL. Older patients with ASCUS showed lower HPV infection rates (P=0.025), but not LSIL (P=0.114). However, the prevalence of CIN2+ was similar between the age groups with ASCUS or LSIL. In patients with ASCUS, the false negative rate of HPV test for CIN2+ was 6.2%. The false negative rate of the HPV test became higher with increasing of the age after the age of 50 (P=0.034). CONCLUSION: Our findings suggest that false negative rate of the HPV test for CIN2+ in ASCUS patients older than 50 years might become higher with increasing of the age. Negative HPV results in patients of the age >50 years with ASCUS should be carefully interpreted.
