RESUMEN

Objective To investigate the expression and significance of cyclin dependent kinase inhibitor 3(CDKN3)in human papillomavirus type 16(HPV16)-positive cervical cancer.Methods CDKN3 expression in pan-cancer was retrieved and downloaded from the Gene Expression Profiling Interactive Analysis(GEPIA)platform,and the expression levels of CDKN3 between normal cervical tissues(13 samples)and cervical cancer tissues(306 samples)were compared.Subsequently,GSE39001 data of HPV16-positive cervical cancer was sourced and downloaded from the Gene Expression Omnibus(GEO)database,and the expression levels of CDKN3 mRNA in HPV16-positive cervical cancer tissues(43 samples)and normal cervical tissues(12 samples)were compared.Immunohistochemical method was used to detect the expression of CDKN3 in 12 ca-ses of HPV16-positive cervical cancer,12 cases of HPV16-positive cervical precancerous lesions,10 cases of HPV16-positive chronic cervicitis and 7 cases of HPV-negative normal cervical samples collected from the Af-filiated Hospital of Guizhou Medical University.SiHa(HPV16-positive),HeLa(HPV18-positive)and HCC94(HPV-negative)cervical cancer cell lines were selected,and their CDKN3 expression were detected by West-ern blot.Results The GEPIA platform analysis showed that CDKN3 was highly expressed in pan-cancer,and the expression level of CDKN3 in cervical cancer tissue was significantly higher than that in normal cervical tissue(P<0.05).The GEO dataset reflected a significantly increased CDKN3 mRNA expression level in HPV16-positive cervical cancer compared to normal cervical tissue(P<0.001).Immunohistochemical verifi-cation showed that the positive expression rates of CDKN3 in HPV16-positive cervical cancer,HPV16-positive cervical precancerous lesion,HPV16-positive chronic cervicitis and HPV-negative normal cervical tissues were 91.7%,58.3%,0 and 0,respectively.Western blot analysis of cervical cancer cells showed that the expression level of CDKN3 in SiHa(HPV16-positive)cells was significantly higher than that in HeLa(HPV18-positive)and HCC94(HPV-negative)cells(P<0.05).Conclusion CDKN3 is a new oncogene of HPV16-positive cer-vical cancer,which may be used as a marker of cervical precancerous lesions and cervical cancer screening,and may provide a theoretical basis for subsequent mechanism research and targeted therapy.

RESUMEN

Introduction: Human Papillomavirus (HPV) infection is the most common sexually transmitted infection in women. About 80% of sexually active women will have contact with this virus at some age in their lives. Most infections will be transient, but when the infection becomes persistent, associated with high oncogenic risk HPV, there may be progression to cancer, especially cervical cancer. The best way to prevent HPV infection is through the use of vaccines. Objective: To assess which are the most prevalent types of HPV in the city of Florianópolis, Brazil and if the majority of the diagnosed types are contained in the HPV vaccines currently available on the market and in the public health sector. Methods: More than 14,727 HPV tests were evaluated for the diagnosis of genital HPV infection in women from Florianópolis. The prevalence of infection was evaluated according to age of the women. HPV detection was performed using molecular biology tests, such as hybrid capture (for diagnosis of the HPV group, high or low oncogenic risk) and PCR (viral genotyping) techniques. Results: The diagnosis of HPV infection was made for women between one and 102 years of age. The highest positivity of the exams was observed in women aged 20­25 years (51% of the exams). The most prevalent age group was 31­35 years old (23.5%), and the lowest was for women aged 70 and above (0.6%). High oncogenic risk HPV was detected in 94.1% of positive samples and was the most frequent in all age groups. Mixed infection (high- and low-risk HPV) was more prevalent in the 66­70 age group (25.6%). The most frequent genotypes were non-16/18 high oncogenic risk HPV (77% of positive cases). HPV 16 was found in 17.1% of positive cases, and HPV 18 in 6.5%. Conclusion: The most prevalent types of HPV in Florianópolis in the last 6 years are non-16/18 high oncogenic risk HPV types, viral types not covered by the current HPV vaccine available in the public health sector in Brazil.


Introdução: A infecção pelo Papilomavírus Humano (HPV)é a infecção sexualmente transmissível mais frequente na mulher. Cerca de 80% das mulheres sexualmente ativas irão entrar em contato com este vírus em algum momento da sua vida. A maioria das infecções será transitória, mas quando a infecção se torna persistente, associada aos HPV de alto risco oncogênico, poderá haver a progressão para o câncer, principalmente o câncer de colo de útero. A melhor forma de prevenção da contaminação pelo HPV é através da utilização das vacinas. Objetivo: Avaliar quais são os tipos de HPV mais prevalentes na cidade de Florianópolis, Brasil, e se a maioria dos tipos diagnosticados estão contidos nas vacinas contra o HPV atualmente disponíveis no mercado e no setor público de saúde. Métodos: Foram avaliados 14.727 exames para diagnóstico da infecção genital pelo HPV em mulheres de Florianópolis, de acordo com a idade das mulheres. A detecção do HPV foi realizada através dos exames de biologia molecular pelas técnicas de captura híbrida (para diagnóstico do grupo de HPV, alto ou baixo risco oncogênico) e PCR (genotipagem viral). Resultados: Foram avaliados exames para diagnóstico da infecção de mulheres entre um e 102 anos de idade. A maior positividade dos exames foi observada em mulheres dos 20­25 anos (51% dos exames). A faixa etária de maior prevalência foi dos 31­35 anos (23,5%), e a menor, após os 70 anos (0,6%). O HPV de alto risco oncogênico foi detectado em 94,1% dos casos positivos e foi o mais frequente em todas as faixas etárias. A infecção mista (HPV de alto e baixo risco) foi mais prevalente na faixa etária dos 66­70 anos (25,6%). Os genótipos mais frequentes foram os HPV de alto risco oncogênico não 16/18 (77% dos casos positivos). O HPV 16 foi encontrado em 17,1% dos casos positivos, e o HPV 18 em 6,5%. Conclusão: Os tipos de HPV mais prevalentes em Florianópolis nos últimos 6 anos são os HPV de alto risco oncogênico não 16/18, tipos virais não cobertos pela atual vacina contra o HPV disponível no setor público de saúde do Brasil.Palavras-chave: HPV. Tipos de HPV. Câncer de colo de útero. Cobertura vacinal.

RESUMEN

RESUMO Objetivo: Identificar a variabilidade espacial da mortalidade por câncer de mama e colo do útero e avaliar fatores associados à mortalidade por esses cânceres no município de São Paulo. Métodos: Entre 2009 e 2016 foram registrados, no Sistema de Informações sobre Mortalidade, 10.124 óbitos por câncer de mama e 2.116 óbitos por câncer do colo do útero em mulheres com 20 anos e mais. Os registros foram geocodificados por endereço de residência e agregados segundo território adstrito. Foram realizadas modelagens de regressão espacial utilizando-se a abordagem bayesiana com estrutura de Besag-York-Mollié para verificar a associação dos óbitos com indicadores selecionados. Resultados: As taxas de mortalidade por esses cânceres apresentaram padrões espaciais inversos. As variáveis associadas à mortalidade por câncer de mama foram: tempo de deslocamento para o trabalho entre uma e duas horas (risco relativo — RR 0,97; intervalo de credibilidade — IC95% 0,93-1,00); mulheres responsáveis pelo domicílio (RR 0,97; IC95% 0,94-0,99) e óbitos por câncer de mama ocorridos em estabelecimentos privados (RR 1,04; IC95% 1,00-1,07). À mortalidade por câncer do colo do útero, estiveram associados: tempo de deslocamento para o trabalho entre meia e uma hora (RR 0,92; IC95% 0,87-0,98); rendimento domiciliar até três salários-mínimos (RR 1,27; IC95% 1,18-1,37); e razão de menores de um ano em relação à população feminina de 15 a 49 anos (RR 1,09; IC95% 1,01-1,18). Conclusão: Foram calculados os RR preditos para a mortalidade por esses cânceres, que estiveram associados às condições socioeconômicas das áreas de abrangência.


ABSTRACT Objective: To identify spatial variability of mortality from breast and cervical cancer and to assess factors associated in the city of São Paulo. Methods: Between 2009 and 2016, 10,124 deaths from breast cancer and 2,116 deaths from cervical cancer were recorded in the Mortality Information System among women aged 20 years and over. The records were geocoded by address of residence and grouped according to Primary Health Care coverage areas. A spatial regression modeling was put together using the Bayesian approach with a Besag-York-Mollié structure to verify the association of deaths with selected indicators. Results: Mortality rates from these types of cancer showed inverse spatial patterns. These variables were associated with breast cancer mortality: travel time between one and two hours to work (RR - relative risk: 0.97; 95%CI - credible interval: 0.93-1.00); women being the head of the household (RR 0.97; 95%CI 0.94-0.99) and deaths from breast cancer in private health institutions (RR 1.04; 95%CI 1.00-1.07). The following variables were associated with mortality from cervical cancer: travel time to work between half an hour and one hour (RR 0.92; 95%CI 0.87-0.98); per capita household income of up to 3 minimum wages (RR 1.27; 95%CI 1.18-1.37) and ratio of children under one year of age related to the female population aged 15 to 49 years (RR 1.09; 95%CI 1.01-1.18). Conclusion: The predicted RR for mortality from these cancers were calculated and associated with the socioeconomic conditions of the areas covered.

RESUMEN

Este estudo teve o objetivo de analisar os fatores associados ao tratamento especializado em tempo inoportuno após diagnóstico do câncer do colo do útero no Estado da Bahia, Brasil. Trata-se de um estudo de base hospitalar, de corte transversal, realizado com mulheres tratadas em unidades credenciadas ao sistema de Registro Hospitalar de Câncer (RHC) do Estado da Bahia, no período de 2008 a 2017. Foi realizada análise descritiva e regressão logística, construída na modelagem stepwise backward, para estimar as razões de prevalência (RP) bruta e ajustada, sendo consideradas estatisticamente significantes aquelas com o valor de p ≤ 0,05 pelo teste qui-quadrado de Pearson. Foram analisados 9.184 casos, destes, 65% tiveram tratamento em tempo inoportuno (tempo transcorrido entre o diagnóstico e o primeiro tratamento > 60 dias). A prevalência de tratamento em tempo inoportuno apresentou valores mais elevados entre mulheres com 65 anos ou mais (RP = 1,30; IC95%: 1,21-1,39), nenhuma escolaridade (RP = 1,24; IC95%: 1,15-1,33) e estadiamento avançado (RP = 1,17; IC95%: 1,13-1,21). Na maioria dos casos analisados, houve tratamento em tempo inoportuno, com maior prevalência entre as mulheres com mais idade, menor escolaridade e estadiamento clínico do tumor avançado, evidenciando a necessidade de ampliação do acesso aos serviços de tratamento oncológico no Estado da Bahia, em especial para estes grupos que apresentaram pior situação.


El objetivo de este estudio fue analizar los factores asociados al tratamiento especializado en un tiempo inadecuado, tras el diagnóstico del cáncer de cuello de útero en el estado da Bahía, Brasil. Se trata de un estudio con base hospitalaria, de corte transversal, realizado con mujeres tratadas en unidades acreditadas en el sistema de Registro Hospitalario de Cáncer (RHC) del estado de Bahía, en el período de 2008 a 2017. Se realizó un análisis descriptivo y regresión logística, construida en el modelado stepwise backward, para estimar las razones de prevalencia (RP) bruta y ajustada, siendo consideradas estadísticamente significativas aquellas con el valor de p ≤ 0,05, mediante el test chi-cuadrado de Pearson. Todos los análisis fueron procesados en el programa Stata versión 16.0. Se analizaron 9.184 casos, de estos, un 65% tuvieron tratamiento en un tiempo inadecuado (tiempo transcurrido entre el diagnóstico y el primer tratamiento > 60 días). La prevalencia de tratamiento en tiempo inoportuno presentó valores más elevados entre mujeres con 65 años o más (RP = 1,30; IC95%: 1,21-1,39), ninguna escolaridad (RP = 1,24; IC95%: 1,15-1,33) y estadio avanzado (RP = 1,17; IC95%: 1,13-1,21). En la mayoría de los casos analizados, hubo tratamiento en un tiempo inadecuado, con mayor prevalencia entre las mujeres con más edad, menor escolaridad y estadio clínico del tumor avanzado, evidenciando la necesidad de una ampliación del acceso a los servicios de tratamiento oncológico en el estado de Bahía, en especial para estos grupos que presentaron peor situación.


This study aimed to analyze factors associated with delay in specialized treatment after diagnosis of cervical cancer in the State of Bahia, Brazil. This was a cross-sectional hospital-based study of women treated in accredited units in the Hospital-Based Cancer Registry (HBCR) system in the State of Bahia from 2008 to 2017. A descriptive analysis and logistic regression were performed with backward stepwise modeling to estimate crude and adjusted prevalence ratios (PR), defining statistical significance as p ≤ 0.05 in Pearson's chi-square test. We analyzed 9,184 cases, and 65% had delayed treatment (time between diagnosis and first treatment > 60 days). Delayed treatment was more prevalent among women 65 years or older (PR = 1.30; 95%CI: 1.21-1.39), with no schooling (PR = 1.24; 95%CI: 1.15-1.33), and in advanced stages (PR = 1.17; 95%CI: 1.13-1.21). Most of the cases analyzed had delayed treatment, more prevalent among older women, with less schooling, and advanced tumor stages, highlighting the need to expand access to cancer treatment services in Bahia state, especially for these groups in worse conditions.

RESUMEN

Objective:To analyze the prognostic factors of patients with Ⅰ B1-Ⅱ A cervical cancers after surgery and to assess the effects and adverse reactions of intensity-modulated radiotherapy(IMRT)combined with concurrent chemotherapy(CCRT). Methods:A retrospective analysis was performed based on the clinical and follow-up data of 362 patients with Ⅰ B1-Ⅱ A cervical cancers who were treated in Changzhou Second People′s Hospital from January 2009 to December 2019. Meanwhile, these patients suffered large primary tumors(LPT; tumors size: ≥4 cm), lymphatic vascular space invasion (LVSI), and deep stromal invasion(DSI; stromal infiltration depth: ≥1/2) after surgery and showed at least one intermediate-risk factor. Among these cases, 161 cases were treated with CCRT, 131 cases under-went single radiotherapy (RT), and 70 cases received unadjuvanted radiotherapy. The Kaplan-Meier method and the logrank test were adopted for univariate survival analysis, the binary logistic regression was used to analyze the recurrence risk, and Cox regression model was used for multivariate survival analysis. Results:The 3 and 5-year overall survival (OS) rates were 94.20% and 88.39%, respectively. The retrospective analysis showed that the risk factors of recurrence included tumor size ≥ 4 cm and poorly differentiated cancers( OR=3.287, 2.870, 95% CI: 1.366-7.905, 1.105-7.457, P<0.05). Compared with the treatment without adjuvant radiotherapy and RT, CCRT reduced the recurrence rate of tumors with tumor size of ≥ 4 cm, adenocarcinomas or adenosquamous carcinomas (pathological types), and poorly differentiated carcinomas( χ2=6.725-7.518, P<0.05). A multivariate analysis showed that the CCRT improved the recurrence-free survival ( HR=0.290, 95% CI: 0.128-0.659, P=0.003) and OS ( HR=0.370, 95% CI: 0.156-0.895, P=0.024). A subgroup analysis indicated that CCRT prolonged the OS of patients with tumor size ≥ 4 cm or poorly differentiated cancers compared to the patients receiving no radiotherapy or those treated with RT (χ 2=7.614, 5.964, P<0.05). Compared with the cases receiving single radiotherapy, those receiving CCRT did not suffer an increase in the incidence of hematology, radiation enteritis, and cystitis above grade 3 according to observation ( P>0.05). Conclusions:Among the intermediate-risk factors leading to the recurrence of postoperative cervical cancers, the factors of large primary tumors or poorly differentiated cancers affect the prognosis of patients.Compared with RT and the treatment without adjuvant radiotherapy, IMRT combined with concurrent chemotherapy can prolong the recurrence-free survival and overall survival of patients with large tumors or poorly differentiated cancers and adverse reactions induced are tolerable.

RESUMEN

RESUMEN El cáncer cérvico uterino es una alteración celular que se origina en el epitelio del cuello del útero debido a la persistencia de serotipos oncogénicos del virus del papiloma humano y que se manifiesta inicialmente a través de lesiones precancerosas de lenta y progresiva evolución. Sigue siendo la primera causa de morbimortalidad en mujeres de países en vías de desarrollo. Los datos estadísticos mundiales indican que al año se producen unos 466.000 nuevos casos, 80 % de ellos en países en vías de desarrollo, de los cuales mueren 274.000 mujeres, a pesar de ser una enfermedad prevenible. El objetivo de esta revisión es compilar información sobre su prevención y tratamiento, para poder ser utilizada con fines docentes.


ABSTRACT Cervical uterine cancer is a cellular alteration which starts in the cervix epithelium due to the persistence of human papillomavirus oncogenic serotypes and that initially manifests itself through precancerous lesions of slow and progressive evolution. It still is the leading cause of morbidity and mortality in women in developing countries. World statistical data indicates that some 466,000 new cases occur each year, 80% of them in developing countries, of which 274,000 women die, despite being a preventable disease. The objective of this review is to compile information on its prevention and treatment, in order to be used for educational purposes.

RESUMEN

Introducción: La citología cervical constituye la principal herramienta para la detección y tratamiento del cáncer de cérvix. Algunos estudios llevados a cabo en población urbana han relacionado la realización y adherencia con los conocimientos, las actitudes y las prácticas favorables de las mujeres con respecto a esta prueba. Objetivo: evaluar los conocimientos, actitudes y prácticas con respecto a la citología cervical en mujeres pertenecientes a un grupo poblacional del ámbito rural. Material y Métodos: estudio de corte transversal-analítico en una población de aproximadamente 3148 mujeres en edad fértil, de ellas se obtuvo una muestra representativa. Se utilizó una encuesta anónima, validada, dirigida, y aplicada por personal de salud capacitado que labora en centros de salud del primer nivel de atención de los distritos de la provincia de Bolívar, La Libertad. Resultados: El 80 por ciento de las mujeres encuestadas tuvo un nivel de conocimiento alto e intermedio, el 70 por ciento una actitud favorable, mientras que el 44 por ciento reportó prácticas correctas en relación con la prueba de citología cervical. El nivel de conocimiento alto e intermedio estuvo asociado a la edad mayor de 30 años (p:0.02), estado civil casada (p:0.05), el mayor grado de instrucción (p:0.00) y el uso de métodos anticonceptivos (p:0.01); no se encontró relación con la edad de inicio de relaciones sexuales (p:0.98). Conclusiones: Existe un alto nivel de conocimientos, actitudes y prácticas correctas hacia la citología cervical en la población rural de la provincia de Bolívar, pero una baja adherencia hacia la misma(AU)


Introduction: Cervical cytology is the main tool for the detection and treatment of cervical cancer. Some studies carried out in the urban population have associated the realization and adherence with knowledge, attitudes and favorable practices of women with respect to this test. Objective: The aim of this study was to determine the level of knowledge, attitudes and practices towards cervical cytology in women of childbearing age in a rural Peruvian province. Material and Methods: A cross-sectional analytical study was conducted in a population of approximately 3148 women of childbearing age, a representative sample was obtained. An anonymous, validated, directed survey was used; it was applied by trained health personnel working in health centers of the primary care level in the districts of the province of Bolívar, La Libertad. Results: A total of 400 surveys were carried out. The results showed that 80 percent of the women surveyed had high and intermediate levels of knowledge, 70 percent had a favorable attitude, while 44 percent reported correct practices related to the cervical cytology test. The high and intermediate levels of knowledge were associated with age over 30 years (p: 0.02), married marital status (p: 0.05), the highest level of instruction (p: 0.00) and the use of contraceptive methods (p: 0.01); no relationship was found with the age of onset of sexual intercourse (p: 0.98). Conclusions: There is a high level of knowledge, attitudes and correct practices towards cervical cytology in the rural population of the province of Bolívar, but a low adherence to it(AU)

RESUMEN

ABSTRACT Objective To describe cervical cancer mortality rates and their corresponding trends, and to analyze the spatial correlations of this type of cancer in Natal-RN, Brazil, between 2000 and 2012. Materials and Methods The simple linear regression model, the empirical Bayes method and the Global Moran's index were used for the statistical analysis. Results The mortality coefficient of cervical cancer in Natal, standardized by age range, was 5.5 per 100 000 women. All historical series for the coefficients studied were classified as stable. The Global Moran's index obtained was 0.048, with a p-value for the spatial test correlation between neighborhoods of 0.300. The average family income by neighborhood showed no significant correlation to cervical cancer mortality rates. Conclusion This study found a temporal stabilization and spatial independence trend of cervical cancer mortality rates in women from Natal, as well as the absence of correlation between these rates and the average family income of the of the participating women distributed by neighborhoods. In view of this, changes in the public policies should be made aimed at preventing the disease; adopting these measures could positively impact the screening program, improving the coverage of Pap smears and immunization campaigns against HPV, in order to reverse this trend and achieve a reduction of mortality rates.(AU)


RESUMEN Objetivo Describir las tasas de mortalidad por cáncer de cuello uterino y sus tendencias, así como analizar las correlaciones espaciales de este tipo de cáncer en Natal-RN, Brasil, entre 2000 y 2012. Materiales y Métodos Para el análisis estadístico se utilizaron el modelo de regresión lineal simple, la estimación empírica de Bayes y el índice Moran Global. Resultados La tasa de mortalidad por cáncer de cuello uterino en Natal, estandarizado por rango de edad, fue 5.5 por cada 100 000 mujeres. Todas las series históricas para los coeficientes estudiados se clasificaron como estables. El índice Moran Global obtenido fue 0.048, con un valor p de 0.300 para la correlación de prueba espacial entre vecindarios. El ingreso familiar promedio por vecindario no mostró correlación significativa con las tasas de mortalidad por cáncer de cuello uterino. Conclusión En este estudio se observó una tendencia temporal de estabilización e independencia espacial de la tasa de mortalidad por cáncer cervical en mujeres de Natal, así como la ausencia de correlación entre estas tasas y el ingreso familiar promedio de las mujeres participantes, distribuidas por vecindarios de la ciudad. En vista de esto, se sugiere que se adopten cambios en las políticas públicas dirigidas a la prevención de la enfermedad que apunten a medidas que puedan tener un impacto positivo en el programa de monitoreo, mejorando la cobertura de la prueba de Papanicolaou, así como de las campañas de vacunación contra el VPH, con el objetivo de revertir esta tendencia y lograr una reducción en las tasas de mortalidad de la enfermedad.(AU)

RESUMEN

OBJECTIVE: To compare response rate and survivals of locally advanced stage cervical cancer patients who had standard concurrent chemoradiation therapy (CCRT) alone to those who had adjuvant chemotherapy (ACT) after CCRT. METHODS: Patients aged 18–70 years who had International Federation of Gynecology and Obstetrics stage IIB–IVA without para-aortic lymph node enlargement, Eastern Cooperative Oncology Group scores 0–2, and non-aggressive histopathology were randomized to have CCRT with weekly cisplatin followed by observation (arm A) or by ACT with paclitaxel plus carboplatin every 4 weeks for 3 cycles (arm B). RESULTS: Data analysis of 259 patients showed no significant difference in complete responses at 4 months after treatment between arm A (n=129) and arm B (n=130): 94.1% vs. 87.0% (p=0.154) respectively. With the median follow-up of 27.4 months, 15.5% of patients in arm A and 10.8% in arm B experienced recurrences (p=0.123). There were no significant differences of overall or loco-regional failure. However, systemic recurrences were significantly lower in arm B than arm A: 5.4% vs. 10.1% (p=0.029). The 3-year progression-free survival (PFS) and 3-year overall survival (OS) of the patients in both arms were not significantly different. The hazard ratio of PFS and OS of arm B compared to arm A were 1.26 (95% CI=0.82–1.96; p=0.293) and 1.42 (95% CI=0.81–2.49; p=0.221) respectively. CONCLUSIONS: ACT with paclitaxel plus carboplatin after CCRT did not improve response rate and survival compared to CCRT alone. Only significant decrease of systemic recurrences with ACT was observed, but not overall or loco-regional failure.

RESUMEN

En Cuba, al igual que en el resto de los países occidentales, el cáncer cérvico-uterino se encuentra en segundo lugar de morbilidad oncológica en mujeres de 20 a 30 años. También hay estudios que revelan información deficiente por parte de las adolescentes en cuanto a las infecciones de transmisión sexual y sus consecuencias, entre las que se encuentra el enfermar de cáncer. Este artículo tiene como objetivo reflexionar acerca de la incidencia de esta enfermedad en edades tempranas, sin embargo el programa para su detección contempla la realización de pruebas citológicas a partir de los 25 años. Se impone entonces pensar en las medidas a tomar para que este flagelo no afecte a mujeres en edades tan tempranas.


In Cuba, as in other western countries, Cervical Uterine Cancer is in the second place of oncological morbidity in women from 20 to 30 years old. There also studies which show deficient information about adolescents regarding sexually transmitted diseases and their consequences, among them developing cancer. This article is aimed at reflecting about the incidence of this disease at early ages; however the program for its detection includes performing cytology starting at 25 year old. It necessary then, to think the measures to be taken so that this scourge does not affect young women.
