Prevalencia y factores de riesgo de la neoplasia intraepitelial anal en pacientes con lesión intraepitelial cervical de alto grado / Prevalence and risk factors for anal intraepithelial neoplasia in patients with high- grade cervical intraepithelial lesion

Resumen OBJETIVO: Determinar la prevalencia de alteraciones en la citología anal, infección anal por virus del papiloma humano y en la neoplasia intraepitelial anal; además, explorar los factores de riesgo y los serotipos asociados en pacientes con lesión intraepitelial cervical de alto grado, a partir de la hipótesis de que esta población tiene mayor riesgo de lesiones precursoras o cáncer anal. MATERIALES Y MÉTODOS: Estudio observacional, descriptivo y transversal, con componente analítico, efectuado en pacientes con diagnóstico de lesión intraepitelial cervical de alto grado (LIEAG) en dos instituciones de salud: una privada y otra pública de Bogotá, atendidas entre enero de 2017 y febrero de 2018. Se efectuó un muestreo no probabilístico, por conveniencia. RESULTADOS: Se incluyeron 119 participantes, en 4 de ellas se evidenció, en la citología anal, el hallazgo de células anormales en el tejido que reviste la parte exterior del cuello uterino. Se encontraron 14 anoscopias anormales que dieron una prevalencia de neoplasia intraepitelial anal del 6.7%. Siete eran neoplasia intraepitelial anal de bajo grado y una de alto grado. Se encontró infección por VPH anal en 45 participantes (37.8%) y se detectaron genotipos de VPH-AR en 29 participantes (24.4%). Más de 3 compañeros sexuales, más de 3 hijos y tener menos de 21 años antes del primer embarazo tuvieron un valor de p < 0.05 que confiere mayor riesgo de infección por VPH anal. CONCLUSIÓN: Es importante establecer en Colombia protocolos para la detección de la neoplasia intraepitelial anal en grupos de alto riesgo, como las pacientes con neoplasia intraepitelial cervical o cáncer de cuello uterino, e incentivar el adiestramiento en la anoscopia de alta resolución en especialistas relacionados con el diagnóstico de patología anogenital.

Abstract OBJECTIVE: To determine the prevalence of alterations in anal cytology, anal human papillomavirus infection, and anal intraepithelial neoplasia, and to explore the risk factors and associated serotypes in patients with high-grade cervical intraepithelial lesion, based on the hypothesis that this population is at higher risk for precancerous lesions or anal cancer. MATERIALS AND METHODS: Observational, descriptive, cross-sectional study, with analytical component, performed in patients diagnosed with high-grade cervical intraepithelial lesion (HG-CIL) in two health institutions: one private and one public in Bogota, visited between January 2017 and February 2018. A non-probabilistic sampling was performed, by convenience, with a sample calculated in 124 patients. RESULTS: 119 participants were included, in 4 of them it was evidenced in the anal cytology, the finding of abnormal cells in the tissue lining the outside of the cervix. Fourteen abnormal anoscopies were found, giving a prevalence of anal intraepithelial neoplasia of 6.7%. Seven were low-grade anal intraepithelial neoplasia and one was high-grade. Anal HPV infection was detected in 45 participants (37.8%) and HR-HPV genotypes were detected in 29 participants (24.4%). More than 3 sexual partners, more than 3 children and being younger than 21 years before first pregnancy had a p-value < 0.05 conferring an increased risk of anal HPV infection. CONCLUSION: It is important to establish protocols in Colombia for the detection of anal intraepithelial neoplasia in high-risk groups, such as patients with cervical intraepithelial neoplasia or cervical cancer, and to promote training in high-resolution anoscopy in specialties related to the diagnosis of anogenital pathology.

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.

[Epidemiological Panorama of Cervical Dysplasia in a First-Level Care Unit]. / Panorama epidemiológico de las displasias cervicales en una unidad de primer nivel de atención.

Background: Cervical cancer (CaCU) is the second cancer-related cause of death for women in Mexico. Early diagnosis and monitoring of patients by cervical cytology and colposcopy are currently the preferred screening methods for identification and prevention of this disease. Objective: To describe the epidemiological panorama of cervical dysplasia diagnosed in a first-level care hospital. Methods: The study was observational, retrospective, unicentric, homodemic, transversal. Records from 6,207 women who attended the General Subzone Hospital with Familiar Medicine #8 (HGSZ/UMF 8), in Tlaxcala, Mexico were analyzed. First-time cervical cytologies were analyzed from 2019 to 2021. Results: Cervical dysplasia was found in 2.6% of the patients being the most frequent type of dysplasia NIC 1. Most of the clinical characteristics of patients with dysplasia were in agreement with those of the Mexican population. Important differences were found (comorbilities, mass index, number of sexual partners, births, positivity to changes related to HPV and vaccination) between two population sets defined by age (younger and older than 40 years). Conclusions: The only factor where a tendency to be associated to type 2 and 3 dysplasia in the population younger than 40 years was the sexually active onset of life younger than 18 years, so this possible association should be evaluated in a bigger population. Our data suggests that risks factors should be evaluated separately for these age groups due to important differences regarding their clinic and epidemiological characteristics as well as changes in risk factor exposure.

Introducción: en México, el cáncer cervicouterino (CaCU) es la segunda causa de mortalidad por cáncer en mujeres. El diagnóstico temprano y monitoreo mediante la citología cervicovaginal y la colposcopía son actualmente los métodos de tamizaje de elección para identificar y prevenir esta enfermedad. Objetivo: describir el panorama epidemiológico de displasias cervicales en un hospital de primer nivel de atención. Métodos: estudio observacional, retrospectivo, unicéntrico, homodémico, transversal. Se analizaron los expedientes de 6207 mujeres atendidas en el HGSZ/UMF No. 8, en Tlaxcala, con citologías vaginales de primera vez, durante 2019-2021. Resultados: se encontró displasia en el 2.6% de las pacientes. El tipo de displasia más frecuente fue NIC 1. Las características clínicas de las pacientes con displasia corresponden a las reportadas en población mexicana, pero se encontraron diferencias importantes (comorbilidades, IMC, NPS, gestas, positividad para cambios asociados al VPH y vacunación) entre dos tipos de población etaria (menores y mayores de 40 años). Conclusiones: el único factor donde hubo una tendencia de asociación al desarrollo de displasia tipo 2 y 3 en la población de más de 40 años fue el inicio de la vida sexual activa antes de los 18 años, por lo que se recomienda buscar una asociación en una población de mayor tamaño y evaluar factores de riesgo en los grupos etarios de manera separada por sus diferencias clínicas, epidemiológicas y factores de riesgo a los que están expuestas.

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.

Effect of Exosomes from Patients with Grade One Cervical Intraepithelial Neoplasia on Cell Cultures: A Preliminary Study.

Purpose: Exosomes are extracellular membrane vesicles. Their content directly reflects the metabolic state of the cells from which they originate and play an important role in cellular functions and pathological states, for example, cancer. The aim was to establish the effect of exosomes from patients diagnosed with CIN1 (grade one cervical intraepithelial neoplasia) on the viability of HeLa cells in culture. It had not been documented, nor had the vesicles obtained by cervicovaginal samples taken by the patients themselves (self-taken vaginal). Patients and Methods: Exosomes were obtained from self-taken vaginal by patients diagnosed with CIN1 and healthy. The exosomes were characterized by determining the AChE (acetylcholinesterase) activity, obtaining a protein profile, and obtaining images of these by STEM. The effect on cell viability was made in HeLa and HaCaT cells in culture. Results: Vesicles between 185 nm and 415 nm were observed by STEM. Exosomes show a "protective" effect when those patients without injury are confronted with HeLa cells. On the other hand, exosomes promote viability when they come from injured patients in the presence of the same cells. Conclusion: Exosomes can be used to identify ideal biomarkers for the early diagnosis of CC (cervical cancer), follow-up of patients, and even treatment given the effects observed on cell cultures.

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

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. The main cause of unsatisfactory samples was insufficient cellularity 6.7% in conventional technique vs 12% of the modified technique, with no significant difference between both techniques p = 0.575 (1.37; 0.45-4.1), findings that reject the working hypothesis. Conclusions: There was no significant difference when using both tests, the samples with satisfactory quality were similar between both techniques.

Human papillomavirus as a single infection in pregnant women from Northeastern Mexico: Cross-sectional study.

BACKGROUND: The role of human papillomavirus (HPV) as single or multiple infections in pregnant women would be relevant to determine the time to progression and/or the time to regression of cervical lesions. OBJECTIVE: In this preliminary study, we determined the prevalence of HPV as single or multiple infections in pregnant women from Northeastern Mexico. MATERIALS AND METHODS: Samples from 31 pregnant and 62 nonpregnant women were examined between January 2015 and November 2015 at UMAE-23 of the Instituto Mexicano del Seguro Social (IMSS). The samples of cervicovaginal exudate were obtained for HPV DNA detection using the INNO-LiPA test, and HPV infections were analyzed as single or multiple infections. Participants completed a questionnaire on sociodemographic, gynecological, obstetric, and sexual behavior characteristics. RESULTS: The mean age of the pregnant women was 25.7 ± 4.8 yr, with an average time of pregnancy of 6 ± 1 months at the time of the study. With respect to age, parity, smoking history, or oral contraceptive use no statistically significant differences between the two studied groups was observed. The HPV infection was 2.7 times higher in pregnant women (35%) than in the control group (13%). In total, 78% of the pregnant women who were HPV-positive presented with single infections compared with 28% of the nonpregnant women. CONCLUSION: A higher prevalence of HPV as a single infection was found in this sample of pregnant Mexican women. Follow-up is necessary to evaluate the persistence or regression of the infection.

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.

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.

Dual p16 and Ki-67 Expression in Liquid-Based Cervical Cytological Samples Compared to Pap Cytology Findings, Biopsies, and HPV Testing in Cervical Cancer Screening: A Diagnostic Accuracy Study.

OBJECTIVE: Our objective was to verify the sensitivity and specificity of dual immunocytochemistry staining for p16 and Ki-67 in liquid-based samples (the "dual" assay) for cervical lesion screening, compared to biopsy findings and human papillomavirus (HPV) DNA molecular detection. STUDY DESIGN: Sensitivity, specificity, and positive (PPV) and negative (NPV) predictive values for the "dual immunocytochemistry assay" were calculated and compared to histopathological results and to high-risk HPV DNA detection in adult women or teenagers submitted to cervical cancer screening. RESULTS: A total of 151 women were included. The majority (96.2%) of those with negative dual assay results had lower biopsy grades (p < 0.001). Women with cytology results suggestive of cervical cancer had positive dual immunocytochemistry assay results more frequently (p < 0.001), and these positive results were also significantly associated with biopsy findings (p < 0.001) and with high-risk genotype HPV infection (p = 0.007). Specificity and PPV for the dual assay were 0.972 (0.855-0.999) and 0.800 (0.284-0.995), respectively, and 1.000 (0.590-1.000) and 1.000 (0.631-1.000) for HPV detection. CONCLUSIONS: The dual immunocytochemistry assay had high specificity and PPV. It reveals a persistent HPV infection, avoiding the need for new tissue collections for biopsies or hybrid capture.

Human Leukocyte Antigen Class I and Class II Polymorphisms and Serum Cytokine Profiles in Cervical Cancer.

Only a small proportion of women who are exposed to infection with high-risk human papillomavirus (HR-HPV) progress to persistent infection and develop cervical cancer (CC). The immune response and genetic background of the host may affect the risk of progression from a HR-HPV infection to lesions and cancer. However, to our knowledge, no studies has been conducted to evaluate the relationship between variability of human leukocyte antigens (HLA) genes and serum cytokine expression in this pathology. In the current study, we examined the associations of HLA alleles and haplotypes including Class I (HLA-A, -B and -C) and II (HLA-DRB1, -DQA1 and -DQB1) with serum levels of cytokines interleukin (IL)-6, tumor necrosis factor-α (TNF-α), IL-10 and IL-17 as well as risks of HPV infections, lesions and CC among admixed Brazilian women. HLA polymorphisms were associated with an increased risk or protection from HPV, lesions and CC. Additionally, we demonstrated a potential association of a HLA class I haplotype (HLA-B*14-C*08) with higher IL-10 cytokine serum levels in cervical disease, suggesting an association between HLA class I and specific cytokines in cervical carcinogenesis. However, larger studies with detailed HPV types coupled with genetic data are needed to further evaluate the effects of HLA and CC by HPV genotype.

Relationship between the risk factors for human papillomavirus infection and lower genital tract precursor lesion and cancer development in female transplant recipients.

BACKGROUND: This study aimed to analyze the relationship between the several risk factors for human papillomavirus (HPV) infection and its persistence and to assess the prevalence of the lower genital tract precursor lesions, cancer, and HPV infection in female transplant recipients, besides the most prevalent HPV types. METHODS: The methodology adopted was a cross-sectional study with a random sample of 61 patients. RESULTS: The results indicated 10 cases (16.4%) of lesions, 54.5% of the overall prevalence of HPV infection, and HPV 16 was the most common high-risk HPV type, followed by HPV 51/53/70. A multiple logistic regression was done and hormone use presented a statistically significant association with high-risk HPV infection (P=.037). No statistically significant association was identified for the set of all factors with the lesions studied. CONCLUSIONS: The high prevalence of HPV infection and its precursor lesions confirmed the importance of differential screening and follow-up of transplanted patients. Condom use must be encouraged. The study result also confirmed the importance of knowledge of the viral type, in order to analyze the impact of HPV immunization, particularly against HPV types that are not 16/18. The reasonable rate of other genotypes, besides the vaccine types, should be considered to evaluate vaccination strategies.

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.

RESUMO CONTEXTO E OBJETIVO: Mundialmente, não existe estratégia única para o gerenciamento ideal de pacientes com laudos de citologia ASCUS ( atypical squamous cells of undetermined significance ). O objetivo do estudo foi determinar o tipo de gerenciamento clínico realizado em mulheres com o primeiro laudo de Papanicolaou ASCUS. DESENHO E LOCAL: Estudo prospectivo de coorte única em uma unidade de patologia cervical em Santiago, Chile. MÉTODOS: Estudo epidemiológico, descritivo, observacional e quantitativo de seguimento de um grupo de mulheres com laudos de citologia ASCUS. RESULTADOS: Na fase de rastreamento, 92.001 relatórios de citologia cervical foram coletados nos ambulatórios da rede pública de saúde. Na fase de diagnóstico, foi selecionada a totalidade de mulheres com relatórios citológicos de ASCUS (n = 446). Essas mulheres foram submetidas a repetição do exame de Papanicolaou, obtendo-se 301 mulheres com resultados normais, 62 mulheres com resultados anormais e 83 que não repetiram o exame. Na fase de confirmação de diagnóstico, as 62 mulheres com resultados anormais foram submetidas a colposcopia e, considerando-se os resultados obtidos, 58 foram submetidas a biópsia. Os resultados das biópsias mostraram 16 mulheres com laudos histológicos negativos, 13 com NIC 1 e 29 com NIC 2 +. Na fase terapêutica, as 42 mulheres com lesões foram submetidas a diversos tratamentos de acordo com o tipo de lesão. Para a fase pós-tratamento, foi instituído um sistema de monitoramento citocolposcópico. CONCLUSÃO: As condutas clínicas tiveram gestão tradicional de rastreamento, diagnóstico, confirmação diagnóstica, tratamento e acompanhamento pós-tratamento.
