Principales indicadores del Programa de Diagnóstico Precoz del Cáncer Cervicouterino en un hospital de Santiago de Cuba

Introducción: El cáncer cervicouterino ocupa el tercer lugar como causa de defunción por neoplasias malignas a nivel mundial, afectando principalmente a los países de ingresos bajos y medianos. Hacia el 2020 se estimó una incidencia de 604 000 nuevos casos. Objetivo: Caracterizar los principales indicadores hospitalarios del Programa de Diagnóstico Precoz del Cáncer Cervicouterino. Métodos: Se realizó un estudio observacional, descriptivo y transversal, que permitió caracterizar los principales indicadores hospitalarios del Programa en el Servicio de Patología de Cuello del Hospital General Dr. Juan Bruno Zayas Alfonso de Santiago de Cuba, de enero del 2020 a diciembre del 2022. La población de estudio estuvo constituida por 443 mujeres. Los datos recopilados fueron analizados mediante técnicas de estadística descriptiva, expresándose en frecuencia y porcentajes. Resultados: De las mujeres estudiadas, 60,9 % presentaron lesión intraepitelial cervical de alto grado de malignidad, con 32,6 % positivo a cáncer cervicouterino. El porcentaje global de pruebas citológicas no útiles fue de 2,07 y sin células de la zona de transformación, de 4,01; ambos indicadores de calidad. Existió una alta significación en cuanto a la tasa de cobertura global de las mujeres en riesgo (K=0,615), demostrando que los resultados de la citología reflejan en gran medida los diagnósticos de la histología, con una buena concordancia. Conclusiones: La prueba citológica cérvico-vaginal sigue siendo el método diagnóstico de mayor valor para detectar neoplasia intraepitelial cervical y carcinoma en estadio precoz en grandes masas de población.

Introduction: Cervical cancer is the third leading cause of death from malignancies worldwide, affecting mainly low- and middle-income countries. By 2020 an incidence of 604,000 new cases was estimated. Objective: To characterize the main hospital indicators of the Cervical Cancer Early Diagnosis Program. Methods: An observational, descriptive and cross-sectional study was carried out to characterize the main hospital indicators of the Program in the Neck Pathology Service of the General Hospital Dr. Bruno Zayas Alfonso of Santiago de Cuba, from January 2020 to December 2022. The study population consisted of 443 women. The data collected were analyzed using descriptive statistic techniques, expressed in frequency and percentages. Results: Of the women studied, 60.9 %had cervical intraepithelial lesion of high degree of malignancy, with 32.6 % positive for cervical cancer. The overall percentage of useless cytological tests was 2.07 and no cells from the processing zone was 4.01, both quality indicators. There was a high significance in terms of the overall coverage rate of women at risk (K=0.615), showing that the results of the cytology largely reflect the diagnosis of histology, with a good agreement. Conclusions: Cervical-vaginal cytology remains the most valuable diagnostic method for detecting cervical intraepithelial neoplasm and early-stage carcinoma in large populations

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.

Validación de la técnica de ganglio centinela en cáncer de cuello uterino en el Hospital de la Mujer

Introducción: el cáncer de cuello (CC) uterino representa un problema de salud pública. En Uruguay ocupa el tercer lugar en incidencia en mujeres, provocando 133 fallecimientos anuales. La afectación ganglionar es uno de sus principales factores pronósticos y condiciona el tratamiento. El ganglio centinela (GC) en estadios precoces de cáncer cervicouterino es una técnica segura que permite una adecuada estadificación y reduce la morbilidad asociada a la linfadenectomía convencional. Objetivo: validar la utilización de la técnica de la biopsia GC en estadios precoces de CC como estándar de tratamiento para la detección de metástasis ganglionares en el Hospital de la Mujer. Material y método: se realizó un estudio prospectivo, longitudinal, de casos. Se incluyó a 30 usuarias con CC en estadios iniciales, en el período comprendido entre enero de 2018 y noviembre de 2022. La marcación se realizó con tecnecio 99m (99mTc). En el mismo acto quirúrgico se realizó la linfadenectomía pélvica sistemática. Resultados: se detectó GC de forma bilateral en 29 de 30 pacientes. Con una tasa de detección por región de 98,3%. En cinco pacientes se detectaron GC metastásicos, no encontrando ganglios no centinela positivos. Una de ellas correspondió a una micrometástasis detectada por ultraestadificación. La sensibilidad fue de 100%: IC95% (56,55 -100) con VPN 100% IC95% (86,68 - 100). Conclusiones: de acuerdo con los resultados arrojados por el estudio, el equipo interdisciplinario del Hospital de la Mujer está en condiciones de utilizar la biopsia de GC de cérvix como estándar de tratamiento en el CC uterino en estadio precoz.

Introduction: Cervical cancer (CC) is a public health problem. In Uruguay, it ranks third in incidence in women, causing 133 deaths annually. Lymph node involvement is one of its main prognostic factors and determines treatment. The sentinel lymph node (SLN) in early stages of cervical cancer is a safe technique that allows for adequate staging and reduces morbidity associated with conventional lymphadenectomy. Objective: To validate the use of the SLN biopsy technique in early stages of CC as the standard treatment for detecting lymph node metastases at the Women's Hospital. Method: A prospective, longitudinal case study was conducted. Thirty patients with early-stage cervical cancer between January 2018 and November 2022 were included in the study. The marking was done with Tc99. Systematic pelvic lymphadenectomy was performed in the same surgical procedure. Results: Sentinel lymph nodes were detected bilaterally in 29 out of 30 patients. With a detection rate per region of 98.3%, metastatic SLNs were detected in 5 patients, with no positive non-sentinel nodes found. One of them corresponded to a micrometastasis detected by ultra-staging. Sensitivity was 100% (95% CI 56.55,100) with a negative predictive value of 100% (95% CI 86.68, 100). Conclusions: According to the results of the study, the interdisciplinary team at the Women's Hospital is in a position to use cervical SLN biopsy as the standard treatment for early-stage cervical cancer.

Introdução: O câncer do colo do útero (CCU) representa um problema de saúde pública. No Uruguai, ocupa o terceiro lugar em incidência em mulheres, causando 133 mortes por ano. O acometimento dos linfonodos é um dos principais fatores prognósticos e condiciona o tratamento. O linfonodo sentinela (LS) em estágios iniciais do câncer do colo do útero é uma técnica segura que permite o estadiamento adequado e reduz a morbidade associada à linfadenectomia convencional. Objetivo: Validar o uso da técnica de biópsia por LS em estágios iniciais do CCU como tratamento padrão para a detecção de metástases linfonodais no Hospital da Mulher. Materiais e métodos: Foi realizado um estudo de caso prospectivo e longitudinal. Trinta usuárias com LS em estágio inicial foram incluídas no período de janeiro de 2018 a novembro de 2022. A marcação foi realizada com Tc99. A linfadenectomia pélvica sistemática foi realizada no mesmo ato cirúrgico. Resultados: O LS foi detectado bilateralmente em 29 das 30 usuárias, com uma taxa de detecção por região de 98,3%. Em 5 pacientes foram detectados LS metastáticos e não foram encontrados nódulos não-sentinela positivos. 1 deles correspondia a uma micrometástase detectada por ultrassonografia. A sensibilidade foi de 100% CI 95% (56,55,100) com NPV 100% CI 95% (86,68, 100). Conclusões: Com base nos resultados do estudo, a equipe interdisciplinar do Hospital da Mulher está em condições de usar a biópsia de LS cervical como padrão de tratamento no câncer cervical em estágio inicial.

Tumor de colisión de útero. Reporte de caso y revisión de la literatura / Uterine collision tumor. Case report and review of he literature

Objetivos: Reportar el caso de una paciente con tumor de colisión del útero y realizar una revisión de la literatura respecto al diagnóstico histopatológico, tratamiento y pronóstico de esta condición. Materiales y métodos: Mujer de 76 años que consultó al centro nacional de referencia del cáncer en Bogotá (Colombia), donde se hizo el diagnóstico de tumor de colisión del útero, compuesto por un adenocarcinoma de endometrio tipo seroso y adenosarcoma de cérvix. Recibió tratamiento quirúrgico más quimioterapia y radioterapia complementaria, falleció a los 16 meses. Se realizó una búsqueda de la literatura en las bases de datos Medline vía PubMed y Embase, que incluía reportes y series de caso de mujeres con diagnóstico de tumor de colisión del útero, y se extrajo información sobre el diagnóstico, tratamiento y pronóstico. Se realizó un resumen narrativo de los hallazgos. Resultados: La búsqueda identificó 36 títulos, de los cuales se incluyeron 14 estudios que incluían 17 pacientes. El diagnóstico histopatológico más frecuente fue el adenocarcinoma endometrioide de endometrio y sarcoma endometrial de alto y bajo grado (47 %). El tratamiento básico fue quirúrgico. Cerca del 50 % recibió tratamiento adyuvante con quimioterapia y radioterapia (15 %). La sobrevida a un año fue del 75 %. Conclusiones: En la literatura no se identificaron casos de tumores de colisión de útero con la histopatología y en la ubicación del caso presentado. La mortalidad a dos años es cercana al 28 % si se toma en cuenta el caso reportado. Se necesitan más estudios que describan la inmunohistoquímica, el tratamiento y el pronóstico de esta condición.

Objectives: To report the case of a patient with a uterine collision tumor and to conduct a review of the literature. Material and methods: A 76-year-old patient who presented to the national cancer referral center in Bogota (Colombia), where she was diagnosed with a uterine collision tumor consisting of a serous-type endometrial adenocarcinoma and a cervical adenosarcoma. The patient underwent surgical treatment followed by chemotherapy and supplemental radiotherapy, and died 16 months later. A search was conducted in the Medline via PubMed and Embase databases, including reports and case series of women with a diagnosis of uterine collision tumor, with retrieval of information regarding diagnosis, treatment and prognosis. A narrative summary of the findings was made. Results: The search identified 36 titles, of which 14 studies with 17 patients were included. The most frequent histopathological diagnosis was endometrial adenocarcinoma and high and low grade endometrial sarcoma (47 %). Primary treatment was surgery and adjuvant treatment with chemotherapy and radiotherapy (15 %) was performed in close to 50 % of cases. One-year survival was 75 %. Conclusions: No cases of uterine collision tumors with the histopathology or in the location of the reported case were found in the literature. If this reported case is taken into account, 2-year mortality is 28 %. Further studies to describe the immunohistochemistry, treatment and prognosis of this condition are needed.

Objetivo : Determinar la relación entre la ausencia de células endocervicales y resultados citológicos Papanicolaou falsos negativos. Material y métodos : Estudio observacional, de enfoque cuantitativo, transversal, relacional y retrospectivo realizado en el Servicio de Anatomía Patológica del Hospital General de Huacho. Se realizó la búsqueda de resultados de biopsias de cuello uterino positivos para lesiones intraepiteliales escamosas y sus respectivos resultados citológicos Papanicolaou previos durante los años 2016 al 2018. Se seleccionó los resultados negativos con ausencia de células endocervicales. Resultados : De los 158 resultados citológicos, 23 mostraron ausencia de células endocervicales y de éstos, sólo dos (8,7%) fueron reportados como negativos. En total 11 (7%) citologías fueron negativas. Conclusiones : No se encontró relación entre la ausencia de células endocervicales y resultados citológicos falsos negativos; por tanto, no influyó de manera significativa en la detección de lesiones escamosas premalignas de cuello uterino.

SUMMARY Objective : To determine the relationship between absence of endocervical cells and false negative Pap smears in patients with squamous premalignant cervix lesions. Methods : A cross sectional study was carried out at Servicio de Anatomía Patológica del Hospital General de Huacho. A search for positive cervix biopsies for squamous intraepithelial lesions and their Pap smears from 2016 to 2018 was done. Negative Pap smears with absence of endocervical cells were investigated. Results : 23 out of 158 cytology results showed absence of endocervical cells, only two (8.7%) were reported negative. Eleven cytologies were negative (7%). Conclusions : No relationship was found between absence of endocervical cells and false negative results at Pap smears. Therefore, no influence in the detection of squamous pre-malignant cells was found.

Comparison of two different doses of hyperbaric bupivacaine for intracavitary radiotherapy in patients with carcinoma cervix ? A randomized control trial

Background: Subarachnoid block has been used for intracavitary radiotherapy (ICRT) for carcinoma cervix, but the literature on the appropriate dose of local anesthetic required to achieve the desired effect is lacking. We compared two different intrathecal doses of 0.5% hyperbaric bupivacaine (1.2 and 1.5 mL) for providing optimal surgical conditions and readiness to discharge in patients undergoing ICRT for carcinoma cervix. Materials and Methods: This prospective double?blind study was done in 80 patients undergoing ICRT. The patients were randomized into two groups (Groups I and II) to receive 1.2 and 1.5 mL of intrathecal hyperbaric bupivacaine, respectively, for ICRT. The level of sensory achieved, the patient satisfaction score, radiation oncologist score, time to L5 regression, and time to motor recovery (walking unaided) were assessed. Statistical Analysis Used: The data were analyzed using SPSS 20 for Windows (IBM, Chicago, IL, USA). Results: The time taken for the block to regress to L5 (Group I: 134.6 � 32.4 minutes vs. Group II: 143.2 � 43.0 minutes, P = 0.31) were comparable. However, the mean time for walking unaided (Group I: 220.87 � 47.12 minutes versus Group II: 247.00 � 49.83 minutes, P = 0.032) after the subarachnoid block was significantly less in Group I. The patient satisfaction with the procedure and overall satisfaction of the radiation oncologists regarding the operating condition were comparable in both the groups. Conclusions: Hence, a 1.2 mL dose of intrathecal hyperbaric bupivacaine for ICRT provides optimal surgical conditions with hemodynamic stability and ensures the early discharge of the patient.

Carcinosarcoma uterino presentándose como masa cervical ­ reporte de un caso

El carcinosarcoma es un tumor poco frecuente que se presenta principalmente en el tracto genital femenino. Su característica más importante es la presencia sincrónica de un componente epitelial maligno (carcinoma) y un componente mesenquimal maligno (sarcoma). Estudios recientes demuestran que la mayoría de las veces el componente sarcomatoso se origina de una diferenciación metaplásica del componente epitelial. Debido a su poca frecuencia, no se conoce con certeza la relación entre las distintas presentaciones histológicas con los posibles factores de riesgo asociados, el pronóstico y la respuesta terapéutica. En este trabajo se reportaron las características histopatológicas y la expresión inmunohistoquímica de un caso de carcinosarcoma uterino en una paciente de 73 años que se presentó inicialmente como una masa cervical. El patrón microscópico documentado fue el de un tumor epitelial de bajo grado asociado a un componente mesenquimal con diferenciación rabdomiosarcomatosa (inmunohistoquímica positiva para desmina y miogenina). La documentación fenotípica es importante para en un futuro desarrollar posibles opciones terapéuticas dirigidas a los distintos patrones histológicos y determinar su posible asociación con factores de riesgo.

Carcinosarcoma is a rare tumor occurring mainly in the female genital tract. Its most important characteristic is the synchronous presence of a malignant epithelial component (carcinoma) and a malignant mesenchymal component (sarcoma). Recent studies show that most of the time the sarcomatous component originates from a metaplastic differentiation of the epithelial component. Due to its infrequency, the relationship between the different histologic presentations with possible associated risk factors, prognosis and therapeutic response is not known with certainty. In this paper we report the histopathologic features and immunohistochemical expression of a case of uterine carcinosarcoma in a 73-year-old female patient who initially presented as a cervical mass. The microscopic pattern documented was that of a low-grade epithelial tumor associated with a mesenchymal component with rhabdomyosarcomatous differentiation (positive immunohistochemistry for desmin and myogenin). Phenotypic documentation is important for future development of possible therapeutic options targeting the different histologic patterns and determining their possible association with risk factors.

The Maternal and Fetal Outcome of Placenta Praevia in Term Pregnancy

Background: Placenta praevia refers to a placenta that is Inserted either completely or partially in the lower uterine segment. In placenta praevia, placenta is implanted in the lower uterine segment within the zone of effacement and dilatation of cervix, resulting in obstruction to decent of the Presenting part. The aim of this study is to find out the maternal and fetal outcome of Placenta praevia in term pregnancy. Material & Methods: This is an observational study. The study used to be carried out in the admitted patient’s Department of obstetrics and gynecology, Dhaka Medical College and Hospital, Dhaka, Bangladesh. In Bangladesh for the duration of the period from January 2013 to June 2013. The duration of the period from Data was entered in MS Excel and Statistical analysis was done using SPSS 24 version. Results: This study shows that Maternal age range was 18 to 45 years and the commonest age group of placentas previa was 25-29 years (60.0%). Four percent were between 20-24 years age group. Twenty percent were more than 35 years of age. Conclusion: The study subjects were selected only who were found high maternal morbidity and perinatal mortality which was 8% due to placenta preavia. So, the observed result of this study might not reflect the expected real outcome. In population therefore further prospective studies with a large sample should be carried out for comprehensive evaluation of placenta Preavia on maternal and neonatal outcome.

Evaluation of variable p16 immunostaining patterns, Ki-67 indices and HPV status in cervical SILs and squamous cell carcinomas: An institutional experience

Objective: The present study evaluates the immunoexpression of p16 and Ki-67 in cervical squamous intraepithelial lesion (SIL) and carcinomas and correlates their expression with clinicopathological features and HPV-DNA status. Material and Methods: A total 36 included cases of SIL and squamous cell carcinoma (SCC) were subjected to p16 and Ki-67 immunostaining. p16 staining was evaluated depending on grading, distribution, localization pattern, intensity and IHC score. Ki-67 expression was graded based on percentage of positive cells. Results: Incidence of HSIL and SCC cases was found to be significantly increased with parity > 5. p16 grade III diffuse nucleocytoplasmic immunostaining was observed in 62.5% LSIL, 80% HSIL and 87% SCC cases. Significant association of p16 staining intensity, IHC score and Ki-67 indices was noted with increasing grades of SILs and carcinomas. Conclusion: Our experience indicates that a combination of p16 and Ki-67 immunostaining may be useful to determine the severity of dysplastic change.

Clinical profile and outcomes in cervical cancer: An audit from a tertiary cancer center

Background: Carcinoma cervix contributes to a major proportion of cancer treatment in tertiary oncology centers. The outcomes are dependent on multiple factors. We conducted an audit to establish the pattern of treatment practiced for carcinoma cervix at the institute and suggest changes thereof to improve the quality of care. Methodology: A retrospective observational study of 306 diagnosed cases of carcinoma cervix was carried out for the year 2010. Data was collected with regards to diagnosis, treatment, and follow-up. Statistical analysis was performed using Statistical Package for Social Sciences (SPSS) version 20. Results: Out of 306 cases, 102 (33.33%) patients received only radiation therapy and 204 (66.66%) patients received concurrent chemotherapy. The most common chemotherapy used was weekly cisplatin 99 (48.52%), followed by weekly carboplatin 60 (29.41%) and three weekly cisplatin 45 (22.05%). Disease-free survival (DFS) at 5 years was 36.6% with patients of overall treatment time (OTT) of <8 weeks and >8 weeks showing DFS of 41.8% and 34% (P = 0.149), respectively. Overall survival (OS) was 34%. Concurrent chemoradiation improved overall survival by a median of 8 months (P = 0.035). There was a trend towards improved survival with three weekly cisplatin regimen, however, insignificant. Stage correlated with improved overall survival significantly with stage I and II showing 40% and stage III and IV showing 32% (P < 0.05) OS. Acute toxicity (grade I-III) was higher in the concurrent chemoradiation group (P < 0.05). Conclusion: This audit was a first of its kind in the institute and threw light on the treatment and survival trends. It also revealed the number of patients lost to follow-up and prompted us to review the reasons for it. It has laid the foundation for future audits and recognized the importance of electronic medical records in the maintenance of data

An enlarged fetal thymus may be the initial response to intrauterine inflammation in pregnant women at risk for preterm birth

SUMMARY OBJECTIVE: Fetal thymus involvement in prematurity has been studied, and this study aimed to evaluate its relationship with short cervix and amniotic fluid sludge in the second trimester of pregnancy. METHODS: In this prospective cross-sectional study, 79 pregnant women (19+0 to 24+6 weeks) were included, and cervical length and the presence or absence of amniotic fluid sludge were evaluated. In the three-vessel view of the fetal thorax, the thymus was identified, and its perimeter and transverse diameter were measured and transformed to a zeta score based on gestational age. RESULTS: Data from 22 women with short cervix (<25 mm) and 57 patients with normal cervix (≥25 mm) were analyzed. The transverse diameter of the fetal thymus was significantly greater in the short cervix group compared to that of the normal cervix group (z-score 2.708 vs. −0.043, p=0.003). There were no significant differences in the perimeter (z-score −0.039 vs. −0.071, p=0.890) or the transverse diameter (z-score 1.297 vs. −0.004, p=0.091) of the fetal thymus associated with the presence (n=21) or absence of sludge (n=58). CONCLUSION: A short cervix is associated with an increased transverse diameter of the fetal thymus during the second trimester of gestation.

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.

Risk Factors for Persistence or Recurrence of High-Grade Cervical Squamous Intraepithelial Lesions / Fatores de risco na persistência ou recidiva da Lesão escamosa intraepitelial de alto grau (LIEAG)

ABSTRACT Objectives: to evaluate whether the colposcopic lesion size , age, kind of surgery, the status of the surgical margins and the expression of the p16 and Ki-67 immunomarkers are risk factors for persistence or recurrence of the lesion. Methods: a cross-sectional, observational, retrospective study of patients submitted to cold knife conization (CKC) or the loop electrosurgical excision procedure for cervical intraepithelial neoplasia 2 or 3. The colposcopic lesion size, age, surgical method, involvement of the surgical margins, and p16/Ki-67 immunomarker expression were analyzed in relation to lesion persistence and recurrence. Results: seventy-one women were treated with cold knife conization and 200 were treated with loop electrosurgical excision. Of these, 95 had cervical intraepithelial neoplasia 2, 173 had cervical intraepithelial neoplasia 3, 183 had free surgical margins, 76 had compromised margins, and 12 showed damage by processing artifact or fragments. Among the 76 cases with positive margins, 55, 11, and 10 showed endocervical margin involvement, ectocervical margin involvement, and both endocervial and ectocervical margin involvement, respectively. Of the 264 followed-up patients, 38 had persistent or recurrent disease. A multiple logistic regression indicated that positive endocervical margins are the only independent risk factor for the persistence/recurrence of cervical intraepithelial neoplasia. No significant association was identified between the colposcopic lesion size, age, surgery type, or p16/Ki-67 immunomarker expression and lesion persistence or recurrence.

RESUMO Objetivos: avaliar se o status das margens, idade, tamanho da lesão colposcópica, tipo de cirurgia e expressão dos marcadores p16/Ki-67 são fatores de risco na persistência ou recidiva da LIEAG. Métodos: um estudo de corte transversal, observacional com coleta de dados retrospectivos de pacientes submetidas a conização a frio (CF) ou exérese da zona de transformação por cirurgia de alta frequência EZT por NIC2/3. Foram analisados os seguintes fatores em relação a persistência ou recidiva: comprometimento das margens, idade, tamanho da lesão, tipo de cirurgia e coexpressão dos imunomarcadores p16 e Ki-67. Resultados: 271 mulheres tratadas com CF (71) e EZT (200), onde 95 apresentavam NIC 2 e 173 NIC 3, 183 apresentaram margens cirúrgicas livres, 76 comprometidas e 12 prejudicadas por artefatos ou fragmentação. Das 76 pacientes com margens comprometidas, 55 foram endocervical, 11 ectocervical e 10 ambas as margens. Das 264 pacientes que tiveram seguimento, 38 persistiram ou recidivaram a doença. A regressão logística múltipla indicou ser a margem endocervical comprometida o único fator independente de risco de persistência/recorrência da NIC (p<0,001). Não houve associação significativa entre a idade, o tamanho da lesão colposcópica, o tipo de cirurgia e a expressão dos imunomarcadores p16/Ki-67 e a persistência ou recorrência da doença. Conclusão: entre os fatores estudados associados com persistência ou recorrência, somente a margem endocervical comprometida provou ser significativamente um fator risco para persistência ou recorrência da lesão.

ABSTRACT We describe the outcomes of The Extension for Community Healthcare Outcomes-Elimination of Cervical Cancer in The Americas (ECHO-ELA) program, which was developed as a tri-lateral cooperation between Pan American Health Organization (PAHO), the U.S. National Cancer Institute (NCI) and The University of Texas MD Anderson Cancer Center (MD Anderson). The program's purpose is to disseminate strategies for cervical cancer prevention and is structured around the three pillars of the World Health Organization's (WHO) Cervical Cancer Elimination Strategy and the associated 90-70-90 target goals. The target audience includes health authorities from Latin American and Caribbean countries, as well as PAHO's non-communicable disease Focal Points in country offices as well as clinical and public health collaborators. The virtual sessions are held in Spanish for 1.5 hours every month using the ECHO® format. From May 2020 to June 2021, 14 ECHO sessions were held with an average of 74 participants per session (range: 46 - 142). We conducted two anonymous surveys (baseline and follow up) and two focus groups. Respondents stated that the topics they learned the most about included the state of HPV vaccination in the region and strategies for implementing HPV vaccination. Identified needs included support between ECHO sessions and country-specific technical assistance. The ECHO-ELA program provides a forum for increased collaboration between countries in Latin America/Caribbean and the dissemination of best-practice strategies to reach the WHO Cervical Cancer Elimination target goals.

Papanicolaou test in Brazil: analysis of the National Health Survey of 2013 and 2019 / Exame de Papanicolaou no Brasil: análise da Pesquisa Nacional de Saúde em 2013 e 2019

ABSTRACT OBJECTIVES To compare the coverage of cervical cancer screening in Brazil in 2013 and 2019, investigating the factors associated with having the test performed and the reasons given for not doing it. Additionally, a comparison is made concerning the time taken to receive the test result in SUS (Sistema Único de Saúde) and in the private health services. METHODS Using data from the National Health Survey (Pesquisa Nacional de Saúde - PNS), prevalence rates and corresponding confidence intervals were calculated to determine the frequency of recent cervical cancer screenings among women aged between 25 and 64 years old in Brazil, for both 2013 and 2019. Poisson regression models were employed to compare the prevalence of the outcome according to sociodemographic characteristics. The reasons for not having the test and the time between performing and receiving the result were also analyzed. RESULTS The findings revealed an increase in the coverage of preventive cervical cancer exams in Brazil from 78.7% in 2013 to 81.3% in 2019. Additionally, there was a decline in the proportion of women who had never undergone the exam, from 9.7% to 6.1%. Prevalence of test uptake was higher among white women, those with higher levels of education and income, and those residing in the South and Southeast regions of the country. The most commonly cited reasons for not taking the test were the impression it was unnecessary (45% in both 2013 and 2019) and never having been asked to undergo the test (20.6% in 2013 and 14.8% in 2019). CONCLUSIONS Despite the high coverage of screening achieved in the country, there is great inequality in access to the test, and a non-negligible number of women are at greater risk of dying from a preventable disease. Efforts must be made to structure an organized screening program that identifies and captures the most vulnerable women.

RESUMO OBJETIVOS Comparar a cobertura do rastreamento do câncer de colo do útero no Brasil em 2013 e 2019, investigar os fatores associados à realização do exame e os motivos informados para não ter realizado, além de comparar o tempo do recebimento do resultado do exame no SUS e na rede privada. MÉTODOS A partir de dados da Pesquisa Nacional de Saúde (PNS) foram calculadas as prevalências e os respectivos intervalos de confiança de realização do exame preventivo do câncer do colo do útero há menos de três anos, em mulheres de 25 a 64 anos, em 2013 e 2019. Modelos de regressão de Poisson foram utilizados para comparar as prevalências do desfecho segundo características sociodemográficas. Também foram analisados os motivos para não ter feito o exame e o tempo entre a realização e o recebimento do laudo. RESULTADOS Houve aumento na cobertura do exame preventivo no Brasil entre 2013 (78,7%) e 2019 (81,3%) e redução na proporção de mulheres que nunca fizeram o exame de 9,7% para 6,1%. A prevalência de realização do exame foi maior em mulheres brancas, melhor escolaridade e renda mais alta, residentes nas regiões Sul e Sudeste. Os motivos mais frequentes para não realizar o exame foram achar desnecessário (45% em 2013 e em 2019) e nunca ter sido orientada a fazê-lo (20,6% em 2013 e 14,8% em 2019). CONCLUSÕES Apesar das elevadas coberturas de rastreamento alcançadas pelo país, há grande desigualdade no acesso ao exame, e uma parcela não desprezível de mulheres está sob maior risco de morrer por uma doença que pode ser evitada. Esforços devem ser feitos para a estruturação de um programa de rastreamento organizado que identifique e capte as mulheres mais vulneráveis.
