ABSTRACT

Objective To investigate the diagnostic value of DNA ploidy analysis combined with immunocytochemistry p16/ki-67 double staining in cervical high grade squamous intraepithelial neoplasia(HSIL) and cervical squamous cell carcinoma(SCC).Methods A total of 73 cases of cytological tests were randomly collected.Among them,53 cases were small DNA ploidy abnormal cells and 20 cases were DNA ploidy negative.The p16/Ki-67 results were detected by immunocytochemistry double staining.With the pathological results as the golden standard,the diagnostic values of DNA ploidy analysis and DNA ploidy analysis combined with p16/Ki-67 double staining in HSIL + was contrastively analyzed by pathologic results.Results Among 20 samples of DNA ploidy negative,the p16/Ki-67 double staining results all were negative.The positive predictive value of DNA ploidy analysis for HSIL + was 34.62%.The sensitivity of DNA ploidy analysis combined with p16/Ki-67 double staining for HSIL + was 84.62%,and its specificity was 92.31%,the positive predictive value was 78.57% and the negative predictive value was 94.74%,which were significantly higher than those of DNA ploidy analysis(P<0.05).Conclusion p16/Ki-67 double staining can significantly im prove the prediction value of HSIL.The DNA ploidy analysis combined with p16/Ki-67 double staining is an effective method for predicting HSIL +,which is suitable for the implementation in the areas with lack of medical resources.

ABSTRACT

INTRODUCCIÓN: El cáncer cérvicouterino es la segunda neoplasia maligna más frecuente en mujeres, cuya solución debe sustentarse en la aplicación de medidas organizativas, el conocimiento de la epidemiología de la afección y el perfeccionamiento de los métodos de detección temprana y tratamiento. OBJETIVOS: Determinar el comportamiento de factores de riesgo de neoplasia intraepitelial cervical en los estratos suburbano y rural de Santa Cruz del Norte. Identificar en los grupos caso y control el comportamiento de algunos factores en las áreas seleccionadas. Comparar el comportamiento de los factores seleccionados entre los estratos suburbano y rural. MÉTODOS: Se realizó un estudio analítico de casos y controles donde se incluyó una muestra constituida por 126 mujeres. Las variables estudiadas estuvieron relacionadas con la esfera sexual y conductual. Se evaluaron los factores de riesgo a través del odds ratio y el cálculo del Test chi-cuadrado. RESULTADOS: Los factores relacionados con los antecedentes de infecciones de transmisión sexual (OR= 3,1 y 9), y el tabaquismo (OR= 6,1 y 7,5) se comportaron como factores de riesgo para ambos estratos. El número de parejas sexuales, solo resultó factor de riesgo para las mujeres de la población suburbana (OR= 4,5). Las diferencias entre las pacientes de los estratos suburbano y rural fueron significativas en todos los factores analizados excepto para la de "el número de partos" (p< 0,05). CONCLUSIONES: Se evidenció que las infecciones de transmisión sexual, y el tabaquismo se comportaron como factores de riesgo para las poblaciones de ambos estratos, a diferencia del uso de anticonceptivos orales, la edad del primer parto, la paridad y el tipo de parto. El número de parejas sexuales, solo resultó factor de riesgo para las mujeres de la población suburbana


INTRODUCTION: The cervicouterine cancer is the second malignant neoplasia more frequent in women, whose solution must to be based in implementation of organizing measures, the knowledge of affection epidemiology and the improvement of early detection methods and of treatment. OBJECTIVES: To determine the behavior of risk factors related to cervical intraepithelial neoplasia in suburban and rural strata of Santa Cruz del Norte municipality. To identify in case-control groups the behavior of some factors in selected areas. To compare the behavior of factors selected among the suburban and rural strata. METHODS: A analytical study of case-controls was conducted including a sample of 126 women. The study variables were related to this sexual and behavioral sphere and the risk factors by odds ratio and the chi² test calculus were assessed. RESULTS: Factors related to a history of sexual transmitted infections (OR= 3.1 and 9) and smoking (OR= 6.1 and 7.5) were considered as risk factors for both sexes. The number of sexual partners only was a risk factor for the suburban female population (OR= 4.5). The differences among patients of suburban and rural strata were significant in all factors analyzed except for that related to the "number of labors" (p< 0.05). CONCLUSIONS: It was evidenced that the sexual transmission infections and smoking were considered as risk factors for populations of both strata unlike the use of oral contraceptives, age in the first labor, parity and the type of labor. The number of sexual partners only was considered a risk factor for the women from the suburban population

ABSTRACT

OBJECTIVE: To survey Human Papilloma Virus (HPV) infection in Chinese Women of Jiangsu Province and discuss the relationship between HPV and the biology of cervical cancer. METHODS: Two thousand, one hundred and fifty-three sexually active women (including 66 cases of cervical cancer) were selected for high-risk human papilloma virus DNA test with Hybrid Capture II (HCII). RESULTS: The overall HPV prevalence was 32.6% (701/2153) with higher positive rates in cervical carcinoma and Cervical Interstitial Neoplasia (CIN) [93.9% and 54.6%] respectively. For women aged 40-59 years, the overall high-risk HPV prevalence was higher than those of other age groups. Compared with CIN I, the positivity rate and viral load of HPV DNA in CIN III is much higher (80.2% vs 29.9%, 11.89 vs 0.53). Ninety-four per cent (64/66) of patients with Cervical cancer were detected to be HPV positive. There was no significant difference in HPV DNA among each clinical stage and pathologic grade. But the positive rates and the value of HPV DNA were higher in the patients with cervical interstitial incursion. Eighty per cent of patients (20/25) could become negative within six months after operation. CONCLUSIONS: High-risk HPV DNA test is effective in screening for cervical diseases. HC II is an effective method to detect HPV DNA.


OBJETIVO: Investigar la infección por el virus del papiloma humano (VPH) en las mujeres chinas de la Provincia de Jiangsu y analizar la relación entre VPH y la biología del cáncer cervical o del cuello uterino. MÉTODOS: Dos mil ciento cincuenta y tres mujeres sexualmente activas (incluyendo 66 casos de cáncer cervical) fueron seleccionadas para una prueba de ADN con el fin de detectar el virus del papiloma humano de alto riesgo mediante Captura Híbrida 2 (HC2). RESULTADOS: La prevalencia general de VPH fue 32.6% (701/2153), hallándose las tasas positivas más altas en el carcinoma cervical y la neoplasia intersticial cervical (NIC) [93.9% y 54.6%]. Para las mujeres de 40-59 años de edad, la prevalencia general de VPH de alto riesgo fue mayor que para los otros grupos etarios. En comparación con el CIN, la tasa de positividad y la carga viral de ADN del VPH en el CIN es mucho mayor (80.2% vs 29.9%, 11.89 vs 0.53). Se detectó que noventa y cuatro por ciento (64/66) de las pacientes con cáncer del cuello uterino eran VPH positivas. No hubo ninguna diferencia significativa en el ADN del VPH ADN entre cada fase clínica y el grado patológico. No obstante, tanto las tasas positivas como el valor de VPH ADN fueron más altos en las pacientes con incursión intersticial cervical. Ochenta por ciento de las pacientes (20/25) podrían volverse negativas en seis meses tras la operación. CONCLUSIONES: La prueba de ADN para la detección del virus del papiloma humano de alto riesgo es un medio efectivo para el tamizaje de las enfermedades cervicales. El HC2 es un método efectivo para detectar el ADN del VPH.

ABSTRACT

Antecedentes: A diferencia de la conización cervical por cono frío, no se ha podido demostrar una clara asociación entre el procedimiento de escisión electro-quirúrgica por asa térmica (LEEP) y el riesgo de parto prematuro. Objetivo: Análisis crítico de la literatura científica, en relación al riesgo de presentar un parto prematuro en pacientes que han sido sometidas a LEEP, y los resultados materno-perinatales asociados. Búsqueda sistemática en múltiples bases de datos. Resultados: Se encontraron sólo tres artículos que cumplían los criterios de inclusión, los cuales son incluidos en esta revisión. De éstos, el primero muestra que el LEEP no aumenta el riesgo de parto prematuro ni de recién nacidos de bajo peso. El segundo evidencia un aumento del riesgo de rotura prematura de membranas y parto prematuro secundario a esto, pero no de parto prematuro espontáneo. Sin embargo, el tercero, señala que el LEEP se asocia en forma significativa a riesgo aumentado de parto prematuro, parto prematuro secundario a rotura prematura de membranas y recién nacidos de bajo peso. Los tres estudios son de cohortes retrospectivas, lo cual les otorga un nivel de evidencia de tipo 2b. Conclusión: La evidencia indica que la excisión de la zona de transformación a través del uso de LEEP está asociada a un pequeño, pero real incremento del riesgo de presentar un parto de pretérmino.


Background: Unlike cold-knife conization, studies have shown conflicting results on the outcome of pregnancy following loop electrosurgical excision procedure (LEEP). Objective: Critical analysis of the literature to establish if the LEEP treatments increase risk of preterm delivery and its influence in maternal-perinatal results. Results: Only three studies were filling the inclusion criteria. The first study does not show that LEEP treatment increase risk of preterm delivery and low birth weight. The second study shows increased risk of premature rupture of membranes and the subsequent preterm delivery, but not spontaneous preterm delivery. Nevertheless, the third study shows increased risk of premature rupture of membranes and the subsequent preterm delivery, spontaneous preterm delivery and low birth weight. The three studies are based in retrospective cohorts, which grant them a level of evidence of type 2b. Conclusion: The evidence indicates that loop excision of the transformation zone by LEEP is associated with a small but real increase the risk of preterm delivery.

ABSTRACT

One hundred and twenty four patients with cervical intra-epithelial neoplasia(CIN group)and 300 women in routine health check(control group)were recruited in the study.Ureaplasma urealyticum(UU)DNA in cervical secretions was detected by fluorescent quantitative PCR(FQ-PCR),and detectopm pf HPV was also performed in 103 CIN cases.The positive rate of UU was 64.5%in CIN group and 38.7%in control group(P<0.05).The results demonstrated that UU infection may be associated with cervical intra-epithelial neoplasia,especially for high-grade lesions;and there may be interaction between UU and HPV infection in development of CIN.
