Expressions of peripheral blood lymphocytes in high-grade squamous intraepithelial lesions of the cervix and early cervical cancer and their significances / 肿瘤研究与临床

Objective:To investigate the expression levels of peripheral blood lymphocytes in patients with high-grade squamous intraepithelial lesions (HSIL) of the cervix and early cervical cancer, and to analyze their correlation with the clinicopathological characteristics of cervical cancer.Methods:The clinical data of 65 patients with HSIL and 78 patients with early cervical cancer (2018 International Federation of Gynecology and Obstetrics stage ≤ stage Ⅱ A) treated in Shanxi Province Cancer Hospital from October 2020 to November 2021 were retrospectively analyzed, and 31 healthy people undergoing physical examination during the same period were treated as the healthy control group. The expressions of CD3 + T cells, CD4 + T cells, CD8 + T cells, NK cells, NK/T cells and other immune cells in fasting peripheral blood of the patients were detected by using flow cytometry. Results:The expression levels of CD3 + T cells, CD4 + T cells, CD4 +/CD8 + and NK cells were 71±8, 39±7, 1.5±0.5, 16±7, respectively in HSIL group, and 73±9, 41±9, 1.5±0.6, 16±9, respectively in early cervical cancer group, which were lower than those in the healthy control group (76±9, 45±10, 2.0±1.3, 20±7) (all P < 0.05). The expression levels of CD8 + T cells was 28±7, 29±8, respectively in HSIL group and early cervical cancer group, which were higher than those in the healthy control group (24±7) (all P < 0.05). The expression level of total B cells in early cervical cancer group was lower than that in healthy control group (10±4 vs.12±3, P < 0.05). The expression level of CD3 + T cells in peripheral blood of early cervical cancer patients with tumor diameter >4 cm and nerve/vascular invasion was 71±10 and 72±8, which was lower than that of patients with tumor diameter 2-4 cm, ≤2 cm and without nerve/vascular invasion (72±8, 75±8, 78±7); the expression level of CD8 + T cell was 32±8 and 35±4, which was higher than that of patients with tumor diameter 2-4 cm, ≤2 cm, and without nerve/vascular invasion (28±8, 28±7, 29±8) (all P < 0.05). The levels of CD3 + T cells and total B cells were negatively correlated with the tumor diameter (all P < 0.05), while the level of CD8 + T cells was positively correlated with tumor diameter ( P < 0.05); the levels of CD3 + T cells and NK cells were negatively correlated with nerve/vascular invasion (all P < 0.05). Conclusions:The immune function of the body starts to change in the early progression of cervical cancer, and is related to the tumor diameter and nerve/vascular invasion of cervical cancer.

T helper cell and regulatory T-cell related cytokines changes in vaginal lavage fluid of patients with high risk-human papilloma virus 16 positive and the predictive effect on the development of cervical neoplasms / 肿瘤研究与临床

Objective:To investigate the changes of T helper cell (Th), regulatory T-cell (Treg cell) related cytokines in vaginal lavage fluid of patients with high risk-human papilloma virus 16 (HR-HPV16) positive and its predictive effect on the development of cervical neoplasms.Methods:A total of 200 cases of HR-HPV16 positive patients who admitted to Xingtai People's Hospital from January 2022 to December 2022 were selected as the experimental group. According to the results of pathological examination, all patients in the experimental group were divided into non pathological group (78 cases), low grade squamous intraepithelial lesion (LSIL) group (49 cases), high grade squamous intraepithelial lesion (HSIL) group (39 cases) and cervical cancer group (34 cases); and 100 healthy people undergoing the physical examination in the same period were taken as the healthy control group. Enzyme-linked immunosorbent assay (ELISA) double-antibody sandwich method was used to detect the levels of interleukin (IL)-2, IL-4, IL-6, IL-10, IL-12, IL-17, tumor necrosis factor α (TNF-α), interferon γ (IFN-γ) and transforming growth factor β (TGF-β) in vaginal lavage fluid of patients in different groups. Multivariate logistics regression was used to analyze the risk factors of cervical cancer, and a nomogram model was established. The receiver operating characteristics (ROC) curve was drawn with pathological results as the gold standard, and the area under the curve (AUC) was calculated to evaluate the predictive ability of the nomogram model.Results:The levels of IL-6, IL-10, IL-17, TNF-α, TGF-β in vaginal lavage fluid of patients in the experimental group were higher than those in the healthy control group, while the levels of IL-2, IL-12 and IFN-γ in the experimental group were lower than those in the healthy control group, and the differences were statistically significant (all P < 0.05); the difference in IL-4 level of both groups was not statistically significant ( P > 0.05). There were statistically significant differences in IL-6, IL-10, IL-17, TNF-α, TGF-β, IL-2, IL-12 and IFN-γ among non pathological group, LSIL group, HSIL group and cervical cancer group (all P < 0.05); the levels of IL-6, IL-10, IL-17, TNF-α, TGF-β in cervical cancer group were the highest, the levels of IL-2, IL-12 and IFN-γ were the lowest; the level of IL-4 in non pathological group, LSIL group, HSIL group and cervical cancer group had no statistically significant difference ( P > 0.05). Logistics regression analysis showed that low IL-2, high IL-4, high IL-6, high IL-10, low IL-12, high IL-17, high TNF-α, low IFN- γ and low TGF-β expressions in vaginal lavage fluid of patients with HR-HPV16 positive were independent risk factors for the development of cervical cancer (all P < 0.05). The results of nomogram analysis showed that IL-6, IL-10, IL-17, TNF-α, TGF-β in vaginal lavage fluid were the factors predicting the development of cervical cancer in HR-HPV16 positive patients. The ROC curve analysis showed that the AUC of nomogram model in predicting the development of cervical cancer in HR-HPV16 positive patients was 0.945 (95% CI 0.901-0.988), and the predictive efficacy was good. Conclusions:Th and Treg cell related cytokines levels in vaginal lavage fluid of patients with HR-HPV16 positive show pathological changes in cervical cancer patients and the above indicators have a high value in predicting the development of cervical cancer.

Detection rate and clinical characteristics of vulvar squamous intraepithelial lesion / 中华妇产科杂志

Objective:To explore the detection rate, clinical characteristics of vulvar squamous intraepithelial lesion (SIL).Methods:Women diagnosed with vulvar high-grade squamous intraepithelial lesions (HSIL) through colposcopy-guided biopsy from January 1, 2018 to August 31, 2022 in Obstetrics and Gynecology Hospital of Fudan University were included in a 1∶1 ratio with patients diagnosed with vulvar low-grade squamous intraepithelial lesions (LSIL) during the same period. Clinical characteristics including human papillomavirus (HPV) infection rate, genotype, cytology result, colposcopy impression, and lesion location were retrospectively analyzed.Results:(1) The proportion of vulvar SIL detected by colposcopy-guided biopsy increased annually from 2018 to 2022, with rates of 1.64% (740/45 057), 2.34% (1 110/47 402), 2.68% (1 108/41 335), 3.26% (1 536/47 078), 3.31% (667/20 155), with an average rate of 2.57% (5 161/201 027). (2) A total of 1 096 cases of vulvar HSIL and 1 096 cases of vulvar LSIL were included. The overall infection rate of HPV was 92.7% (1 993/2 150), with higher infection rate in vulvar HSIL patients than that in vulvar LSIL patients [96.0% (1 012/1 054) vs 89.5% (981/1 096); χ2=33.62, P<0.001]. Among vulvar HSIL patients, the common HPV genotype from high to low were HPV 16 (66.7%), HPV 52 (14.3%), and HPV 58 (10.0%). For vulvar LSIL patients, the most common HPV genotype were respectively HPV 16 (24.9%), HPV 6 (20.1%) and HPV 52 (17.1%). The overall sensitivity rate of cytology was 53.6%, with no significance difference between vulvar LSIL and HSIL groups (54.3% vs 52.9%; χ2=0.40, P=0.526). The accuracy of colposcopy impression for vulvar HSIL was lower than that for vulvar LSIL [40.2% (163/405) vs 81.7% (380/465); χ2=158.72, P<0.001]. About 57.3% (1 257/2 192) of the patients had concomitant cervical and vaginal lesions, with a higher rate in vulvar HSIL group than that in vulvar LSIL group [62.6% (686/1 096) vs 52.1% (571/1 096); χ2=24.67, P<0.001]. Unifocal lesion was the main type, with no significance difference between vulvar LSIL and HSIL groups [81.4% (381/468) vs 82.5% (386/468); χ2=0.18, P=0.671]. The most common lesion locations were the posterior commissure, followed by labia minora, vaginal vestibule, labia majora, perianal and clitoris. Conclusions:The detection rate of vulvar SIL under colposcopy is about 3%, and the infection rate of HPV is 92.7%. Vulvar SIL, especially vulvar HSIL, is likely to cause concomitant cervical and vaginal lesions. The accuracy of colposcopy in diagnosing vulvar HSIL is low. Therefore a comprehensive and careful examination of the vulva is necessary and suspicious vulvar lesions should be undergone colposcopy-guided biopsy for diagnosis.

Risk Profile of High-grade Cervical Lesions and Cervical Cancer Considering the Combination of Cytology, HPV Genotype, and Age among Women Undergoing Colposcopy / Perfil de risco de lesões cervicais de alto grau e câncer cervical considerando a combinação de citologia, genótipo do HPV e idade entre mulheres submetidas a colposcopia

Abstract Objective The present study aims to establish a risk profile for high-grade cervical lesions and cervical cancer (CIN2 + ) in women undergoing colposcopy at the Hospital do Câncer de Barretos, through the analysis of Human Papillomavirus (HPV) infection, cervical cytology, and patient's age. Methods Retrospective cross-sectional study based on a computerized database of women aged ≥ 18 years old who underwent colposcopy at the Prevention Department of the Hospital do Câncer de Barretos from 2017 to 2019. Results A total of 3,411 women were included, 58.0% were positive for high-risk-HPV test, with a higher prevalence of CIN2+ for HPV16 (30.3%) and other HPV (45.0%). Cytological findings that suggest invasive cervical cancer (squamous cells or adenocarcinoma), regardless of the status of HPV test, showed 100% diagnosis of CIN2 + , while atypias that suggest high-grade lesions, HSIL and ASC-H, positive for HPV test, showed in 86 and 55.2%, respectively, diagnosis of CIN2 + . ASC-H cytological results among women aged > 40 years old and negative HPV were mainly associated with benign findings. We observed that ≤ CIN1 has a higher prevalence among older women with negative HPV, while for high-grade lesions there is an increase among young women HPV16- and/or 18-positive. In cancer diagnosis, we observed a predominance of HPV 16/18 regardless of the age group. Conclusion The highest risks of precursor lesions and cervical cancer were found among women with positive HPV 16/18 tests and severe cytological atypia in population screening tests. In addition, cytological findings of ASC-H HPV negative in women > 40 years old usually represent benign findings in histological investigation.

Resumo Objetivo Estabelecer um perfil de risco de lesões intraepiteliais de alto grau e câncer do colo do útero (NIC2 + ) em mulheres submetidas a colposcopia considerando-se a infecção pelo papilomavírus humano (HPV), citologia cervical e idade. Métodos Estudo retrospectivo transversal em banco de dados informatizado de mulheres com idade ≥ 18 anos que realizaram colposcopia no departamento de Prevenção de Câncer no Hospital do Câncer de Barretos/SP no período de 2017 a 2019. Resultados Foram incluídas 3.411 mulheres, sendo 58,0% positivas para HPV de alto risco, e maior prevalência de NIC2+ para HPV16 (30,3%) e outros HPV (45,0%). Resultados citológicos sugestivos de lesões invasivas (epidermoide ou adenocarcinoma), independente do teste de HPV, apresentaram 100% de diagnóstico NIC2 + , enquanto atipias sugestivas de lesões de alto grau, HSIL e ASC-H, associados a HPV positivo, apresentaram 86 e 55,2%, respectivamente. Resultados citológicos de ASC-H entre mulheres > 40 anos e HPV negativo foram associados principalmente a achados benignos. Observamos que ≤ NIC1 apresenta uma maior prevalência entre mulheres mais velhas com HPV negativo, enquanto para lesões de alto grau, há um aumento entre mulheres mais jovens positivas para HPV16/18. Para diagnóstico de câncer, observamos que há um predomínio de HPV16/18 independente da faixa etária. Conclusão Foi identificado maior risco de lesões precursoras e câncer entre mulheres com HPV 16/18 positivo e atipias citológicas graves em testes de rastreio populacional. Além disso, resultados citológicos de ASC-H quando associados a HPV negativo com idade > 40 anos habitualmente representam achados benignos em investigação histológica.

Small cell neuroendocrine carcinoma with adenocarcinoma and high grade squamous intraepithelial neoplasia of the cervix

ABSTRACT Neuroendocrine neoplasm (NEN) of the cervix is a malignant tumor and is classified into low and intermediate-grade neuroendocrine tumor (NET), and high-grade small cell neuroendocrine carcinoma (SCNEC), and large cells neuroendocrine carcinoma (LCNEC). SCNEC of the cervix is an Infrequent tumor with an incidence of less than 1% of all gynecological malignancies. It is characterized by small to medium-sized tumor cells with scant cytoplasm and neuroendocrine differentiation. Most cases of SCNEC of the cervix manifest in pure forms, and only cases show coexisting, non-neuroendocrine component of HPV-associated adenocarcinoma or squamous cell carcinoma. In this report, reviewing the literature, we present one such unique case of SCNEC of the cervix with adenocarcinoma and high-grade squamous intraepithelial neoplasia.

Association of Swede Score and 2011 IFCPC Nomenclature in Women with Abnormal Cytology / A Associação entre o escore Swede e a nomenclatura IFCPC 2011 em mulheres com citologia anormal

Abstract Objective To assess the association between two colposcopic indices, the Swede score and the 2011 International Federation of Cervical Pathology and Colposcopy (IFCPC) Nomenclature as well as to determine the efficacy of the Swede score with cutoffs of 7 and 8. Methods In the present cross-sectional pilot study, 34 women who had at least 1 colposcopy-directed biopsy due to abnormal cytology were enrolled. The colposcopic findings were scored by both the Swede score and the 2011 IFCPC Nomenclature and were compared with each other. The Kappa coefficient and the McNemar test were used. Accuracy, sensitivity, specificity, and positive and negative predictive values (NPV and PPV, respectively) were calculated, as well as the effectiveness with cutoffs of 7 and 8 in identifying cervical intraepithelial neoplasm (CIN) 2+ when using the Swede score. Results The correlation between the 2 colposcopic indices was 79.41%. The Kappa coefficient and the McNemar p-value were 0.55 and 0.37, respectively. The IFCPC Nomenclature had sensitivity, specificity, accuracy, PPV, and NPV of 85.71, 55.00, 67.64, 57.14, and 84.61%, respectively. The Swede score had sensitivity, specificity, accuracy, PPV, and NPV of 100, 63.15, 79.41, 68.18, and 100%, respectively. A Swede score cutoff of 7 for CIN 2+ detection had a specificity of 94.73%, while with a cutoff of 8 it increased to 100%. The sensitivity for both values was 60%. The PPV and NPV for cutoffs of 7 and 8 were 90 and 75 and 100 and 76%, respectively. Conclusion Although both colposcopic indices have good reproducibility, the Swede score showed greater accuracy, sensitivity, and specificity in identifying CIN 2 + , especially when using a cutoff of 8.

Métodos Trata-se de um estudo transversal, com 34 mulheres incluídas, que realizaram colposcopia com biópsia dirigida devido a uma citologia anormal. Os achados colposcópicos foram categorizados pelo escore Swede e pela Nomenclatura IFCPC 2011 e comparados um com o outro. Foram avaliados o coeficiente Kappa e o teste de McNemar e foram calculados a acurácia, a sensibilidade, a especificidade e valores preditivos negativos e positivos (VPN e VPP, respectivamente) de cada índice, assim como a eficácia com os pontos de corte 7 e 8 do escore Swede para determinar as lesões de neoplasia intraepitelial cervical (NIC) 2 + . Resultados A concordância entre os 2 índices foi de 79,41% e o coeficiente Kappa e o valor-p do teste de McNemar foram 0.55 e 0.37, respectivamente. Pela Nomenclatura IFCPC 2011, obtivemos como sensibilidade, especificidade, acurácia, VPP e VPN, respectivamente: 85,71, 55,00, 67,64, 57,14 e 84,61%. Pelo escore Swede obtivemos como sensibilidade, especificidade, acurácia, VPP e VPN, respectivamente: 100, 63,15, 79,41, 68,18 e 100%. O uso do escore Swede para detecção das lesões NIC 2+ obteve como especificidade 94,73% com o valor de corte de 7, enquanto o valor de corte 8 obteve 100%. A sensibilidade para ambos os cortes foi de 60%. O VPP e o VPN com os cortes 7 e 8 foram, respectivamente: 90,00 e 75,00 e 100,00 e 76,00%. Conclusão Ambos os índices colposcópicos tiveram boa reprodutibilidade; no entanto, o escore Swede mostrou melhor acurácia, sensibilidade e especificidade em identificar as lesões NIC 2+ e o melhor ponto de corte para identificar as lesões NIC2+ foi com o valor 8.

Clinicopathological analysis of postoperative pathological diagnosis upgrade of post-menopausal high-grade cervical squamous intraepithelial lesions in women / 肿瘤研究与临床

Objective:To investigate postoperative pathological diagnosis upgrade of high-grade cervical squamous intraepithelial lesions (HSIL) in postmenopausal women and its influencing factors.Methods:Clinicopathologic data of 378 post-menopausal women with HSIL who underwent cervical conization or total hysterectomy in Shanxi Bethune Hospital between January 2017 and December 2021 were retrospectively analyzed. According to whether the pathological diagnosis was upgraded after operation, they were divided into upgraded group and non-upgraded group. The clinicopathological characteristics of both groups were compared. Multivariate logistic regression was used to analyze the influencing factors of postoperative pathological upgrade.Results:Among 387 patients, 28 patients (7.2%) were postoperatively upgraded to cervical cancer. Compared with the non-upgraded group, the proportions of the following indexes in the upgraded group were higher [the proportion of HSIL detected by cervical thinprep cytologic test (TCT): 57.1% (16/28) vs. 44.6% (160/359); the proportion of HSIL detected by colposcopic impression: 89.3% (25/28) vs. 59.3% (213/359); the proportion of glandular involvement: 46.4% (13/28) vs. 24.0% (86/359); the number of lesion involvement ≥ 2: 82.1% (23/28) vs. 59.6% (214/359); the proportion of positive endocervical curettage (ECC): 64.3% (18/28) vs. 46.0% (165/359)]; and the differences were statistically significant (all P < 0.05). There were no statistically significant differences in the proportions of patients stratified by menopausal duration, colporrhagia, gravidity frequency, reproductive frequency, human papillomavirus (HPV) 16/18 infection and multiple HPV infection (all P > 0.05). Multivariate logistic analysis found that colposcopic impression of HSIL ( OR = 6.195, 95% CI 1.432-26.804), glandular involvement ( OR = 2.468, 95% CI 1.050-5.801), and ECC positive ( OR = 3.477,95% CI 1.028-11.764) were independent risk factors for postoperatively upgraded to cancer for postmenopausal HSIL patients in women (all P < 0.05). Conclusion:For post-menopausal women, patients with colposcopic impression of HSIL, glandular involvement and ECC positive should be alert to the risk of postoperatively pathological upgrade.

Alterações em exames citopatológicos realizados em Unidade Básica de Saúde: um estudo analítico transversal / Alterations in cytopathological tests performed in a Basic Health Unit: a cross-cutting analytical study

Objetivo: Com o presente estudo, buscou-se verificar a quantidade de exames de colpocitologia oncótica coletados em Unidade Básica de Saúde (UBS) escolhida, determinar quantas e quais são as alterações encontradas nesses exames e quais foram as condutas e acompanhamentos realizados em pacientes com exames alterados. Métodos: Foram analisados 446 exames de colpocitologia oncótica realizados em uma UBS do centro-oeste do Paraná. As pacientes com exame alterado foram selecionadas e foi feita uma análise desses prontuários a fim de verificar a conduta e o acompanhamento dessas pacientes. Resultados: Foram encontrados 32 exames com alterações, sendo três de uma mesma paciente. Dessas 30 pacientes, a grande maioria correspondia a células escamosas atípicas de significado indeterminado (ASC-US), possivelmente não neoplásicas, e 28 pacientes retornaram para receber uma conduta inicial, sendo principalmente o encaminhamento para a coleta de novo preventivo em seis meses ao serviço de oncologia clínica. Conclusão: O presente estudo concluiu que a hipótese principal foi verdadeira, a qual foi descrita como prevalência significativa de lesões intraepiteliais de alto grau, embora não seja a mais frequente, e descontinuidade por parte das pacientes que obtiveram esse resultado. Além disso, notou-se grande encaminhamento à atenção terciária, o que não é indicado pelo Ministério da Saúde.(AU)

Objective: With the present study, we sought to verify the amount of cytopathological tests collected in the chosen basic health unit, to determine how many and what are the alterations found in these tests and what were the conducts and follow-ups performed in patients with altered exams. Methods: We analyzed 446 preventive tests performed in a basic health unit in the Midwest of Paraná, and patients with altered examination were selected and an analysis of these medical records was made in order to verify the conduct and follow-up of the patients. Results: Thirty-two tests with alterations were performed, 3 of which were the same patient. Of these 30 patients, the vast majority corresponded to atypical cells of squamous meaning ­ possibly non-neoplastic (ASC-US), and 28 patients returned to receive an initial approach, mainly being referred to the collection of preventive new in 6 months and to the clinical oncology service. Conclusion: The present study concluded that the main hypothesis was true, which was described as a significant prevalence of high-grade intraepithelial lesions (HSIL), although not the most frequent, and discontinuity on the part of the patients who obtained this result. In addition, there was a large referral to tertiary care, which is not indicated by the Ministry of Health.(AU)

Estudio Descriptivo: Colposcopia en el diagnóstico de lesiones de cuello uterino en el Hospital de Especialidades José Carrasco Arteaga, Cuenca ­ Ecuador. 2015-2019 / Descriptive Study: Colposcopy as a diagnostic method for cervix lesions in Hospital de Especialidades Jose Carrasco Arteaga, Cuenca-Ecuador. 2015-2019

INTRODUCCIÓN: El cáncer de cuello uterino es un problema de salud pública, siendo una de las principales causas de morbilidad y mortalidad en países en vía de desarrollo. Para el screening y diagnóstico de las lesiones del cuello uterino se realiza citología cervical (Papanicolaou). Ante un reporte de citología sospechosa, la colposcopia es un procedimiento imprescindible en la evaluación del tracto genital inferior para detectar lesiones tempranas y cáncer. El objetivo de la presente investigación fue caracterizar los procedimientos colposcópicos realizados, como método diagnóstico y terapéutico, en las pacientes con resultados anormales del Papanicolaou. MATERIALES Y MÉTODOS: El presente es un estudio observacional, descriptivo de corte transversal, cuyo universo lo conformaron todas las pacientes con diagnóstico citológico anormal en Papanicolaou, que se realizaron un procedimiento colposcópico entre el año 2015 hasta el año 2019 en el Hospital José Carrasco Arteaga, con un total de 1 628 pacientes. RESULTADOS: Se incluyen 1 628 procedimientos colposcópicos. El 55.46% de la población estuvieron entre los 27 a 46 años de edad. El estado civil predominante fue casada (75%). El 63.45% de las mujeres iniciaron vida sexual entre los 21 a 30 años. El 95.20% de las pacientes tuvieron entre 1 y 3 parejas sexuales. Los resultados de Papanicolaou anormales representan; el 37.28% a LIE-BG, seguido de 35.81% con ASC-US y 14.18% como LIE-AG. El 67.32% de colposcopías fueron satisfactorias. Se realizó biopsia en el 71% de las pacientes, seguido de la toma de muestra de cono con ASA-LEEP (13.69%), legrado endocervical en el 11.05%. Los resultados de anatomía patológica reportaron LIE-AG en 46.56% de los casos, seguido de 22.23 % como LIE-BG y cervicitis crónica en el 16.27%, 12.28% de los resultados fueron negativos. CONCLUSIÓN: Tres cuartas partes de las colposcopias se realizaron en mujeres entre los 27 y 56 años de edad. Los resultados anormales más frecuentemente encontrados en el Papanicolaou fueron: LIE-BG, seguido de ASC-US. 67% de las colposcopias realizadas fueron satisfactorias. Tras la colposcopia, en la mayoría de pacientes se realizó biopsia, en un menor porcentaje y en orden de frecuencia: conización electro quirúrgica con asa (ASA-LEEP), legrado endocervical e histerectomía diagnóstica. Los resultados de anatomía patológica reportaron LIE-AG en el 46.56%, LIE-BG en el 22.23 % como y cervicitis crónica en el 16.27%; 12.28% de estudios fueron negativos.(au)

BACKGROUND: Cervical cancer is a public health issue, being one of the main causes of morbidity and mortality in developing countries. Cervical cytology (Papanicolaou) is performed for screening and diagnosis of cervical lesions. In case of a suspicious cytology report, colposcopy is an essential procedure for evaluation of the lower genital tract, to detect early lesions and cancer. The aim of this study was to characterize the colposcopy procedures performed, as a diagnostic and therapeutic method, in patients with abnormal Papanicolaou results. METHODS: This is an observational, descriptive cross-sectional study, whose universe were all the patients with abnormal cytological diagnosis in pap smear, who underwent a colposcopy procedure between 2015 and 2019 at Hospital José Carrasco Arteaga, with a total of 1 628 patients. RESULTS: 1 628 colposcopic procedures were included. 55.46% of the population were between 27 to 46 years of age. The predominant marital status was married status (75%). 63.45% of women had their first sexual experience between 21 and 30 years of age. 95.20% of the patients had between 1 and 3 sexual partners. Abnormal pap smear results represent; 37.28% to LSIL, followed by ASC-US (35.81%), and HSIL (14.18%). 67.32% of colposcopies were classified as satisfactory. Biopsy was performed in 71% of the patients, followed by loop electrosurgical excision procedure (LEEP) (13.69%), endocervical curettage in 11.05%. The pathology results reported HSIL in 46.56% of the cases, followed by 22.23% as LSIL and chronic cervicitis in 16.27%, 12.28% of the results were negative. CONCLUSION: Three-quarters of all colposcopies were performed on women between 27 and 56 years of age. The most frequently abnormal Pap smear results were: LSIL, followed ASC-US. 67% of the colposcopies were satisfactory. After colposcopy, biopsy was performed in most of the patients, in lower percentage: loop electrosurgical excision procedure (LEEP), endocervical curettage and diagnostic hysterectomy. Pathology results reported HSIL in 46.56%, LSIL IN 22.23% and chronic cervicitis in 16.27%; 12.28% of studies were negative.(au)

Application of vaginoscopy in the diagnosis and treatment of occult vaginal high-grade squamous intraepithelial lesions / 中华妇产科杂志

Objective:To investigate the application value of vaginoscopy in the diagnosis and treatment of vaginal squamous intraepithelial lesions post hysterectomy.Methods:From May 2017 to June 2020, patients with high-risk (HR)-HPV infection and (or) cytological abnormalities after hysterectomy in Obstetrics and Gynecology Hospital Affiliated to Fudan University were examined by colposcopy, and those who were not satisfied with exposure under colposcopy were further examined by vaginoscopy. The role of vaginoscopy in the detection and treatment of occult vaginal squamous intraepithelial lesions was analyzed.Results:A total of 153 patients with HR-HPV infection and (or) cytological abnormalities, and inadequate colposcopy were enrolled in this study. The average age was (49.8±8.1) years. All cases were successfully performed vaginoscopy with no vaginal perforation, no bladder and intestinal injury. During vaginoscopy, 11 (7.2%, 11/153) cases with unclear high-grade squamous intraepithelial lesion (HSIL) boundary under colposcopy were found with clear HSIL boundary, and new HSIL was found in 23 (15.0%, 23/153) cases. According to colposcopy, there were 89 cases of normal or inflammation, 45 cases of vaginal low-grade squamous intraepithelial lesion (LSIL) and 19 cases of vaginal HSIL. According to vaginoscopy, there were 56 cases of normal or chronic inflammation, 55 cases of vaginal LSIL, 40 cases of vaginal HSIL (including 2 cases of vaginal HSIL could not exclude cancer) and 2 cases of vaginal carcinoma. There were significant difference between colposcopy and vaginoscopy ( P<0.01). The missed diagnosis rate of vaginal apex blind curettage under colposcopy was 54.8%. For the 40 cases with vaginal HSIL under vaginoscopy, 15 cases were completely curettaged with vaginal endoscopic claw forceps, and 22 cases were vaporized by Versapoint. Among the 37 cases of vaginal HSIL treated by vaginoscopy, 34 cases were followed up for 6 months with 31 cases of vaginal HSIL cured. The cure rate was 91.2% (31/34), the positive rate of HR-HPV decreased from 100.0% (34/34) to 79.4% (27/34). Conclusion:For patients with inadequate exposure of vaginal apex during colposcopy posthysterectomy, vaginoscopy is helpful to detect the occult lesions in the vaginal apex, and it could also be used for the treatment of vaginal squamous intraepithelial lesions.

Avaliar a estrogenização tópica vaginal no seguimento de citologia oncótica de significado indeterminado, tipo ASC-H, na pós-menopausa. Estudo, tipo caso-controle, que avaliou mulheres menopausadas com diagnóstico de ASC-H, divididas em dois grupos, com e sem uso de estrogênio tópico vaginal (GE e GNE). Foi calculada razão de chance a partir de tabelas de contingência construídas com variação robusta. Foram analisados 128 prontuários, sendo 27% de pacientes do GNE e 72% do GE. Houve aumento de diagnósticos ASC-H no GNE. No GE, aproximadamente 68 vezes menos colposcopias inadequadas e diminuição do número de colposcopias e Cirurgia de Alta Frequência (CAF), com evidência na redução em 21 e 12,5 vezes, respectivamente. Diminuição do número de colposcopias com melhor adequação ao exame, número de biópsias inalterado e diminuição do número de cirurgias de alta frequência, no grupo com uso de estrogênio tópico vaginal durante o seguimento.

Current paper evaluates topic vaginal estrogenization following oncotic cytology of undetermined significance, type ASC-H, in postmenopausal women. A case-control study evaluated menopausal women diagnosed with ASC-H, divided into two groups, with and without the use of topic vaginal estrogen (GE and GNE). Odds ratios were calculated from contingency tables built with robust variation. 128 medical records were analyzed, 27% of which were from the GNE and 72% from the GE. There was an increase in ASC-H diagnoses in GNE. In GE, approximately 68 times less inappropriate colposcopies and a decrease in the number of colposcopies and High Frequency Surgery (HFS), with a reduction of 21 and 12.5 times, respectively. Decrease in the number of colposcopies with better adaptation to the exam, unchanged number of biopsies and decrease in the number of high-frequency surgeries, in the group using topic vaginal estrogen during the follow-up.

Resumen Introducción: Actualmente, el cáncer de cérvix sigue siendo una enfermedad importante por su incidencia y mortalidad. Aunque se conoce su etiología generada por la infección del virus del Papiloma Humano (PVH) y sus métodos de tamizaje como la citología convencional y el test de ADN-PVH, aún es necesario reconocer diversas características que se relacionan con la aparición de este tipo de cáncer. Objetivo: Describir las características citológicas previas al diagnóstico de cáncer cervical en mujeres de una institución de salud de la ciudad de Medellín. Materiales y métodos: Estudio descriptivo. Se tomaron los registros clínicos correspondientes a mujeres con diagnóstico confirmado de cáncer de cérvix entre 2012 y 2017 y se revisaron los resultados de citología previos al diagnóstico. Se realizó análisis univariado para describir las variables de estudio. Resultados: La muestra de mujeres con cáncer fue de 714, la mediana de edad fue 51 años (rango intercuartílico: 42-60), la alteración citológica más frecuente fue lesión intraepitelial de alto grado (33,8%), el principal cáncer diagnosticado fue carcinoma escamocelular (70,6%). Conclusiones: Los resultados de citología alteradas son un indicador para riesgo de cáncer de cérvix, de ahí la importancia de continuar con el protocolo de tamizaje establecido.

Abstract Introduction: Currently, cervical cancer continues to be an important disease because of its high incidence and mortality. Even though its etiology (Human Papilloma Virus infection) and screening methods (conventional cytology and HPV-DNA test) are well known, understanding the various characteristics associated with the appearance of cervical cancer is fundamental. Objective: To describe the cytological characteristics that precede the diagnosis of cervical cancer in women diagnosed in a health care institution from the city of Medellín. Materials and methods: A descriptive study. The clinical records corresponding to women with a confirmed diagnosis of cervical cancer between 2012 and 2017 were used. Also, the citology results obtained before the diagnosis were reviewed. An univariate analysis was carried out in oder to describe the study variables. Results: The sample size of women with cervical cancer was 714, the age median was 51 years old (interquartile range: 42-60), the most frequent cytological alteration was high-grade intraepithelial lesion (33.8%), and the main diagnosed cancer type was squamous cell carcinoma (70.6%). Conclusions: Results showing an altered cytology are indicators of cervical cancer risk. Therefore, it is important to continue with the stablished screening protocol.

Implementación de la nueva guía práctica clínica para la detección y manejo de lesiones precancerosas de cuello uterino en mujeres de la ciudad de Cali, Colombia / Implementation of the new clinical practice guideline for the detection and management of precancerous lesions of the cervix in women from the city of Cali, Colombia

Objetivos del trabajo: Se determinaron los porcentajes de las lesiones precancerosas de cuello uterino en un grupo de mujeres diagnosticadas positivas por la prueba ADN-VPH. Materiales y métodos: El presente estudio es un análisis exploratorio descriptivo transversal de una base de datos con resultados de las pruebas de ADN-VPH (genotipo y tipo de infección), citología y colposcopia, realizadas en 58 mujeres de 30 años o más, para el periodo de octubre del 2018 a febrero del 2019. Resultados: De las 58 mujeres positivas para la prueba ADN-VPH, el 57% (n=33) fueron positivas para la prueba citológica cervical. De este grupo de mujeres fueron diagnosticadas negativas para LEI el 21% (n=7); para LEI-BG el 33% (n=11); y para LEI-AG el 45% (n=15) mediante la prueba de colposcopia. El VPH-16 mostró la mayor frecuencia relativa de detección en las LEI-AG con un 46,7% (n=7). Igualmente, los genotipos que cubre la vacuna Gardasil_4 fueron identificados en mayor porcentaje en las LEI-AG en comparación con los otros tipos histopatológicos diagnosticados, siendo esta asociación estadísticamente significativa, valor de p = 0,033. Conclusiones: La implementación de la nueva guía de práctica clínica para la detección y manejo de lesiones precancerosas de cuello uterino muestra resultados satisfactorios, siendo concordante la detección de ADN-VPH, con la identificación de anormalidades citológicas e histopatológicas, permitiendo la identificación precoz de mujeres en riesgo de desarrollar cáncer cervical.

Objectives of the study: To determine the percentages of precancerous lesions in the cervix in a group of women with positive diagnostic to the DNA-HPV test. Materials and methods: The present study is a cross-sectional exploratory analysis of a database with information on the results of DNA-HPV tests (genotype and type of infection), cytology and colposcopy, carried out on 58 women aged 30 or older, for the period from October 2018 to February 2019. Results: Of the 58 women positive for the DNA-HPV test, 57% (n=33) were positive for the cervical cytology test. Of this group of women, 21% (n=7) were diagnosed LEI-negative; for LEI-BG 33% (n=11); and for LEI-AG, 45% (n=15) using the colposcopy test. HPV-16 has a higher detection frequency in the LEI-AG with 46.7% (n=7). Likewise, the genotypes that cover the Gardasil_4 vaccine were members in a greater percentage in the LEI-AG in comparison with other diagnosed histopathological types, this association being statistically significant, value of p = 0.033. Conclusions: The implementation of the new clinical practice guideline for the detection and management of precancerous lesions of the cervix shows satisfactory results, the DNA-HPV detection being consistent, with the identification of cytological and histopathological abnormalities, allowing the early identification of women at risk to develop cervical cancer.

Pathologic discrepancies between colposcopy-directed biopsy and loop electrosurgical excision procedure of the uterine cervix in women with cytologic high-grade squamous intraepithelial lesions / 부인종양

OBJECTIVE: To investigate pathologic discrepancies between colposcopy-directed biopsy (CDB) of the cervix and loop electrosurgical excision procedure (LEEP) in women with cytologic high-grade squamous intraepithelial lesions (HSILs).METHODS: We retrospectively identified 297 patients who underwent both CDB and LEEP for HSILs in cervical cytology between 2015 and 2018, and compared their pathologic results. Considering the LEEP to be the gold standard, we evaluated the diagnostic performance of CDB for identifying cervical intraepithelial neoplasia (CIN) grades 2 and 3, adenocarcinoma in situ, and cancer (HSIL+). We also performed age subgroup analyses.RESULTS: Among the study population, 90.9% (270/297) had pathologic HSIL+ using the LEEP. The diagnostic performance of CDB for identifying HSIL+ was as follows: sensitivity, 87.8%; specificity, 59.3%; balanced accuracy, 73.6%; positive predictive value, 95.6%; and negative predictive value, 32.7%. Thirty-three false negative cases of CDB included CIN2,3 (n=29) and cervical cancer (n=4). The pathologic HSIL+ rate in patients with HSIL− by CDB was 67.3% (33/49). CDB exhibited a significant difference in the diagnosis of HSIL+ compared to LEEP in all patients (p<0.001). In age subgroup analyses, age groups <35 years and 35–50 years showed good agreement with the entire data set (p=0.496 and p=0.406, respectively), while age group ≥50 years did not (p=0.036).CONCLUSION: A significant pathologic discrepancy was observed between CDB and LEEP results in women with cytologic HSILs. The diagnostic inaccuracy of CDB increased in those ≥50 years of age.

The usefulness of high-risk HPV hybrid capture in patients with squamous cell atypia in cervical cytological examination / A utilidade da captura híbrida para o HPV de alto risco em pacientes com atipia de células escamosas na colpocitologia

ABSTRACT Introduction: The cervical cytological examination and the investigation of high-risk human papillomavirus (HPV) deoxyribonucleic acid (DNA) are well-known valuable tools for screening of cervical lesions, since they allow the early diagnosis of cancer and its precursor lesions. Objective: This study aimed to evaluate the ability of high-risk HPV DNA detection by hybrid capture to predict intraepithelial lesions and cancer in patients with initial cervical cytological diagnosis of atypical squamous cells (ASC). Method: Retrospective analysis of histological or cervical cytological results after one-year follow-up from hybrid capture for high-risk HPV DNA research in patients with previous ASC diagnosis. Sensitivity, specificity and positive and negative predictive values of hybrid capture were calculated in relation to the identification of squamous intraepithelial lesions. Results: Among the 163 patients previously diagnosed with ASC and absence of high-risk HPV DNA, nine (5.5%) showed low-grade (LSIL) or high-grade squamous intraepithelial lesion (HSIL) during the follow-up. On the other hand, among the 110 patients presenting ASC and high-risk HPV DNA positivity, 43 (39%) showed cervical lesions within one year. Sensitivity and specificity values and positive and negative predictive values applied to hybrid capture for the identification of squamous intraepithelial lesions were 82.3%, 69.3%, 38.1%, and 94.4%, respectively. Conclusion: Our results showed a high negative predictive value of hybrid capture for cervical lesions detection, in patients with previous diagnosis of ASC, when the high-risk HPV DNA research was negative.

RESUMEN Introducción: La colpocitología y la investigación del ácido desoxirribonucleico (ADN) del virus del papiloma humano (VPH) de alto riesgo son herramientas bien conocidas para la detección de lesiones cervicales, puesto que permiten el diagnóstico precoz del cáncer y sus lesiones precursoras. Objetivo: El objetivo de este estudio es evaluar la capacidad de detección del ADN-VPH de alto riesgo por captura híbrida en predecir lesiones intraepiteliales y cáncer en pacientes con diagnóstico colpocitológico inicial de atipia de células escamosas (ASC). Método: Análisis retrospectivo de resultados histológicos y citológicos después de un año de seguimiento desde la captura híbrida para investigación de ADN-VPH de alto riesgo en pacientes con diagnóstico previo de ASC.

Conclusão: Nossos resultados mostraram alto valor preditivo negativo da captura híbrida para detecção de lesões cervicais em pacientes com diagnóstico prévio de ASC, quando a pesquisa do DNA-HPV de alto risco foi negativa.

Factores de riesgo en las lesiones intraepiteliales del cuello uterino / Risk Factors in Intraepithelial Lesions of the Cervix

RESUMEN Fundamento: los factores de riesgo de las lesiones intraepiteliales se comportan similares a los del cáncer cervicouterino. Objetivo: identificar la influencia de distintos factores de riesgo relacionados con la aparición de lesiones intraepiteliales de cuello uterino. Método: se realizó un estudio observacional de casos y controles en el Policlínico Docente Gustavo Aldereguía de la provincia Granma en el período comprendido desde el 1ro de enero del 2016 hasta el 30 de junio del 2017. Se definieron como casos a las 105 pacientes con neoplasia intraepitelial cervical confirmadas histopatológicamente y como controles a las mujeres que se les realizó la prueba citológica, seleccionadas por muestreo simple aleatorio. A cada paciente se le realizó: interrogatorio, examen físico y medios de diagnóstico. Para el análisis de los factores de riesgo se utilizó una estrategia univariada y multivariada. Se delimitaron como variables explicativas aquellos factores considerados como hipotéticamente de riesgo y que serían sometidos a evaluación. Como variable respuesta se consideró la aparición de la neoplasia intraepitelial. Se obtuvieron estimaciones puntuales y por intervalo de confianza del 95 %. Resultados: la sepsis vaginal y menarquía precoz fueron significativas, no así el no uso del condón, infección por virus del papiloma humano, anticoncepción oral, edad, dispositivo intrauterino y tabaquismo como factores indiferentes. La erosión y sepsis vaginal fueron los más significativos por el modelo de regresión logística. Hubo interacciones entre cervicitis, múltiples parejas sexuales y tabaquismo; moderadamente significativo se comportaron la edad y la menarquía precoz; cervicitis y erosión, infección por el virus del papiloma humano y múltiples parejas sexuales. Conclusiones: se determinó que la sepsis vaginal y la erosión cervical presentaron una asociación estadísticamente significativa e importante con la probabilidad de aparición de las lesiones intraepiteliales propias del cuello uterino.

ABSTRACT Foundation: the risk factors of intraepithelial lesions behave similar to those of cervical cancer. Objective: to identify the influence of different risk factors related to the appearance of intraepithelial lesions of the cervix. Method: an observational case-control study was carried out in the Gustavo Aldereguía Teaching Polyclinic of the Granma province in the period from January 1, 2016 to June 30, 2017. The 105 patients with cervical intraepithelial neoplasia were defined as cases histopathologically confirmed and as controls to women who underwent the cytological test, selected by simple random sampling. Each patient was performed: interview, physical examination and diagnostic means. For the analysis of risk factors, a univariate and multivariate strategy was used. Explanatory variables were defined as factors considered as hypothetically risky which would be subject to evaluation. The appearance of intraepithelial neoplasia was considered as a response variable. Punctual and 95 % confidence interval estimates were obtained. Results: vaginal sepsis and early menarche were noticeable, however not the use of condoms, human papillomavirus infection, oral contraception, age, intrauterine device and smoking as indifferent factors. Erosion and vaginal sepsis were the most significant due to the logistic regression model. There were interactions between cervicitis, multiple sexual partners and smoking; moderately significant were age and early menarche; cervicitis and erosion, human papillomavirus infection and multiple sexual partners. Conclusions: it was determined that vaginal sepsis and cervical erosion presented a statistically significant and important association with the probability of the appearance of intraepithelial lesions of the cervix.

Diagnóstico y tratamiento de las lesiones intraepiteliales escamosas de alto grado del cuello uterino / Diagnosis and treatment of high grade squamous intraepithelial lesions of uterine cervix

INTRODUCCIÓN. El cáncer cérvico-uterino tiene una fase precursora de larga duración, pues debe pasar por varios estados previos al cáncer invasivo, denominados lesiones intraepiteliales, de bajo y de alto grado, que pueden transformarse en lesiones malignas. La importancia de un diagnóstico oportuno y certero de las lesiones intraepiteliales escamosas de alto grado radica en que, si son tratadas de manera oportuna, son ciento por ciento curables. OBJETIVO. Proporcionar información actualizada sobre el diagnóstico y tratamiento de las lesiones precursoras de cáncer de cérvix y ayudar a los profesionales en la toma de decisiones médicas. MATERIALES Y MÉTODOS. Estudio de revisión de 45 artículos científicos la gran mayoría de la última década y, unos pocos, con datos históricos vigentes sobre lesiones intraepiteliales escamosas de alto grado del cuello uterino. La búsqueda se realizó en MedLine, PLoS y Scielo utilizando los términos tamizaje, neoplasias uterinas, lesiones intraepiteliales escamosas de cuello uterino y tratamiento. RESULTADOS. Los artículos científicos fueron seleccionados por niveles de evidencia 1 y 2, con recomendaciones A y B. Las recomendaciones de inicio de tamizaje han cambiado y el manejo toma en cuenta el riesgo acumulado por tipo de lesión. El tratamiento, en la mayoría de casos, es la escisión y resulta definitivo. CONCLUSIÓN. El diagnóstico sigue siendo cito-colpo-histológico y el tratamiento depende de la edad de la paciente, pudiendo las posibilidades ir de la observación hasta la escisión quirúrgica y, en casos específicos, la histerectomía.

INTRODUCTION. Cervical-uterine cancer has a long-term precursor phase, as it must go through several states prior to invasive cancer, called intraepithelial lesions, low and high grade, which can become malignant lesions. The importance of a timely and accurate diagnosis of high-grade squamous intraepithelial lesions is that, if treated in a timely manner, they are one hundred percent curable. OBJECTIVE. Provide updated information on the diagnosis and treatment of precursor lesions of cervical cancer and assist professionals in medical decision making. MATERIALS AND METHODS. Review study of 45 scientific articles the vast majority of the last decade and, a few, with current historical data on high-grade squamous intraepithelial lesions of the cervix. The search was conducted in MedLine, PLoS and Scielo using the terms screening, uterine neoplasms, squamous intraepithelial lesions of the cervix and treatment. RESULTS. The scientific articles were selected by levels of evidence 1 and 2, with recommendations A and B. The recommendations for starting screening have changed and management takes into account the accumulated risk by type of injury. The treatment, in most cases, is excision and is definitive. CONCLUSION. The diagnosis is still cyto-histological and the treatment depends on the age of the patient, and the possibilities may range from observation to surgical excision and, in specific cases, hysterectomy.
