ABSTRACT

Introdução: O câncer de boca é comumente diagnosticado de forma tardia, comprometendo a qualidade de vida dos indivíduos ou os levando a óbito. Objetivo: Verificar a tendência temporal da mortalidade por câncer de boca no Estado do Rio de Janeiro e da cobertura da Estratégia Saúde da Família (ESF) e de equipes de saúde bucal (ESB). Método: Estudo ecológico com análise da tendência temporal da mortalidade por câncer de boca, entre 1999 e 2018, e da cobertura da ESF e ESB, no período de 2002 a 2018, no Estado e Regiões de Saúde. Utilizou-se a regressão linear generalizada de Prais-Winsten no cálculo das tendências para o Estado, cada Região de Saúde, sexo, faixa etária e localização do tumor. Resultados: Houve tendência de mortalidade por câncer de boca decrescente no Estado e nas Regiões Metropolitana I e II; nas demais Regiões de Saúde, foi estacionária. As tendências dos óbitos em homens, das faixas etárias 40 a 59 anos e 80 anos ou mais, foram decrescentes. Na localização do tumor, houve tendência decrescente entre óbitos por outras partes e partes não especificadas (C06) e uma tendência crescente na mortalidade por câncer de base de língua (C01). Na cobertura de ESF e ESB, na maioria das Regiões de Saúde e no Estado, a tendência foi crescente. Conclusão: A tendência decrescente na mortalidade por câncer de boca e a tendência crescente de ESF e ESB, no Estado do Rio de Janeiro, não foram observadas em todas as Regiões de Saúde


Introduction: Oral cancer is usually diagnosed late, compromising the individuals' quality of life or causing death. Objective: Check the time trend of mortality by oral cancer in the State of Rio de Janeiro and the coverage of the Family Health Strategy (FHS) and oral health teams (OHT). Method: Ecological study with analysis of the time trend of mortality by oral cancer, between 1999 to 2018 and the coverage of the FHS and OHT, in the period from 2002 to 2018, in the State and Health Regions. Generalized linear regression of Prais-Winsten to calculate trends for the state, each Health Region, sex, age group and tumor location was utilized. Results: Declining trends in mortality by oral cancer in the State and in the Metropolitan I and II Regions. In the other Health Regions, it was stationary. The trends of deaths in men, aged 40 to 59 years and 80 years or more were decreasing. In the location of the tumor, there was a decreasing trend among deaths in other and unspecified parts (C06) and a raising trend in mortality by cancer of the Tongue Base (C01). In the coverage of FHS and OHT in most Health Regions and in the State, the trend was rising. Conclusion: Declining trend in oral cancer mortality and the raising trend of FHS and OHT in the State of Rio de Janeiro was not observed for all Health Regions

ABSTRACT

Introdução: O câncer bucal ainda é destacado como preocupante problema de saúde pública. Objetivo: Verificar a tendência de mortalidade por câncer bucal por Região brasileira e fatores de risco, avaliando o intervalo de tempo entre o diagnóstico e o tratamento. Método: Estudo com dados secundários do DATASUS (taxa de mortalidade e tempo para tratamento) e do Vigitel (consumo de álcool e cigarro); análises de séries temporais e correlações entre taxas de mortalidade (2010-2019) e consumo de álcool e cigarro (2010-2019), para idade superior a 40 anos, e análise descritiva do tempo entre diagnóstico e tratamento. Resultados: Houve aumento da tendência de câncer bucal por Regiões e sexo, com predominância para o sexo masculino. A variação percentual anual (VPA) da ingestão de álcool e o uso de cigarro foram considerados estacionários na maioria das Regiões analisadas. Ao correlacionar as variáveis, verificou-se correlação estatisticamente significativa entre taxa de mortalidade (2010-2019) e percentual de consumo de álcool (p=0,011; r=0,957), percentual de consumo de cigarro (p=0,019; r=0,936) e taxa bruta de mortalidade em homens (2019) (p=0,005; r=0,97). Verificou-se que, na maioria dos casos (74%), o tempo para início do tratamento é de mais de 60 dias. Conclusão: Embora o consumo de álcool e o tabagismo sejam fatores de risco para o câncer bucal, o presente estudo concluiu que houve aumento da mortalidade por câncer e os fatores de risco analisados permaneceram estacionários. O início de tratamento foi maior do que 60 dias a partir do diagnóstico. Palavras-chave: neoplasias bucais/mortalidade; tabagismo; consumo de bebida alcoólica; estudos de séries temporais; saúde pública


Introduction: Oral cancer still stands out as a concerning public health issue. Objective: Verify the trend of oral cancer mortality by Brazilian regions and risk factors, evaluating the time interval between diagnosis and treatment. Method: Study with secondary data from DATASUS (mortality rate and time to treatment) and Vigitel (alcohol and cigarette use). Time series analyzes and correlations were performed among mortality rates (2010-2019) and alcohol and cigarette use (2010-2019) for over 40 years of age. Descriptive analysis of the time between diagnosis and treatment was also performed. Results: There was an increase in the tendency to oral cancer by region and sex, with a predominance of males. The annual percentage change (APC) of alcohol intake and cigarette use was considered stationary in most regions analyzed. When correlating the variables, there was a statistically significant correlation for mortality rate (2010-2019) and percentage of alcohol use (p=0.011; r=0.957), percentage of cigarette use (p=0.019; r=0.936) and crude mortality rate in men (2019) (p=0.005; r=0.97). It was found that most cases (74%) take more than 60 days to start treatment. Conclusion: Although alcohol and tobacco use are risk factors for oral cancer, the present study showed an increase in cancer mortality and stationary for the risk factors analyzed. The beginning of the treatment was over 60 days after diagnosis


Introducción: El cáncer oral todavía se destaca como un problema de salud pública preocupante. Objetivo: Verificar la tendencia de la mortalidad por cáncer bucal por región brasileña y factores de riesgo, evaluando el intervalo de tiempo entre el diagnóstico y el tratamiento. Método: Estudio con datos secundarios de DATASUS (tasa de mortalidad y tiempo de tratamiento) y Vigitel (consumo de alcohol y cigarrillos). Se realizaron análisis de series de tiempo y correlaciones entre las tasas de mortalidad (2010-2019) y el consumo de alcohol y cigarrillos (2010-2019) para los mayores de 40 años. También se realizó un análisis descriptivo del tiempo transcurrido entre el diagnóstico y el tratamiento. Resultados: Hubo un incremento en la tendencia al cáncer bucal por región y sexo, con predominio del sexo masculino. El cambio porcentual anual (APV) de la ingesta de alcohol y el consumo de cigarrillos se consideró estacionario en la mayoría de las regiones analizadas. Al correlacionar las variables, hubo una correlación estadísticamente significativa para tasa de mortalidad en hombres (2010- 2019) y porcentaje de consumo de alcohol para hombres (p=0,011; r=0,957), porcentaje de consumo de cigarrillos en hombres (p=0,019; r=0,936) y tasa bruta de mortalidad en hombres (2019) (p=0,005; r=0,97). Se encontró que la mayoría de los casos (74%) demoran más de 60 días en comenzar el tratamiento. Conclusión: Aunque el consumo de alcohol y el tabaquismo son factores de riesgo para el cáncer oral, el presente estudio mostró un aumento en la mortalidad por cáncer y estacionario para los factores de riesgo analizados. Hubo un alto porcentaje de inicio del tratamiento durante 60 días después del diagnóstico

ABSTRACT

Introdução: Anualmente, no Brasil, 15 mil pessoas são diagnosticadas com câncer de boca, e quase metade delas morre. Sergipe está entre os sete Estados brasileiros com maiores índices. Objetivo: Analisar a tendência temporal e a distribuição espacial da mortalidade por câncer de boca em Sergipe entre 2007 e 2016. Método: Estudo ecológico de série temporal de base populacional, utilizando técnicas de análise espacial. Os dados de mortalidade foram obtidos no Sistema de Informação sobre Mortalidade (SIM). A análise das tendências temporais foi realizada no modelo de regressão de Joinpoint por meio da regressão de Poisson. Foram realizadas análises espaciais utilizando o estimador de intensidade Kernel e os índices de Moran Global e Local. Resultados: Foram analisadas 543 mortes por câncer de boca. Os casos mais frequentes ocorreram em homens (74%), com idade média de 64 anos e baixa escolaridade. As taxas de mortalidade global (variação percentual anual ‒ APC=2,5; IC 95% 0,9-6,7) e masculina (APC=2,96; IC 95% 1,2-5,6) aumentaram. Houve também uma tendência crescente de mortalidade por câncer na língua (APC=10,05; IC 95% 3,8-16,7). A mortalidade relacionada a outras localizações anatômicas foi estável. Houve concentração de óbitos nas Regiões Metropolitana, Centro-Sul e Centro-Agreste. Conclusão: Durante o período analisado, a taxa de mortalidade geral mostrou uma tendência crescente, com concentração nas Regiões Centro-Sul, Central e Metropolitana, sendo necessário manter medidas de prevenção e controle contra o câncer de boca em todo o Estado de Sergipe


Introduction: Annually, in Brazil, 15 thousand individuals are diagnosed with oral cancer and almost half of them die. Sergipe is among the seven Brazilian states with the highest rates. Objective: To analyze the temporal trend and the spatial distribution of oral cancer mortality in Sergipe between 2007 and 2016. Method: Population-based time series ecological study, using techniques of spatial analysis. Mortality data were obtained from the Mortality Information System (SIM). The analysis of temporal trends was performed with the Joinpoint regression model using Poisson regression. Spatial analyzes were carried out using the Kernel intensity estimator and the Moran Global and Local indexes. Results: 543 oral cancer deaths were analyzed. The most frequent cases were in men (74%), with an average age of 64 years and low education. The overall and male's mortality rates (annual percent change ‒ APC=2.5; 95% CI 0.9-6.7 and APC=2.96; 95% CI 1.2- 5.6), respectively, increased. There was also an increasing trend of mortality by tongue cancer (APC=10.05; 95% CI 3.8-16.7). Mortality related to other anatomical locations was stable. There was a concentration of deaths in the Metropolitan, Midsouth and Mid-rural regions. Conclusion: During the period investigated, the general mortality rate showed an increasing trend, with concentration in the Midsouth, Mid and Metropolitan regions, and it is necessary to maintain preventive and control measures against oral cancer throughout the State of Sergipe

ABSTRACT

Abstract Pathological parameters have been indicated as tumor prognostic factors in oral carcinoma. Objective: The objective of this study was to investigate the impact of pathological parameters on prognosis of patients affected only by tongue and/or floor of the mouth squamous cell carcinoma (SCC). Methodology: In total, 380 patients treated in the Brazilian National Cancer Institute (INCA) from 1999 to 2006 were included. These patients underwent radical resection followed by neck dissection. The clinical and pathological characteristics were recorded. The Kaplan-Meier method and Cox proportional hazards model were used in survival analysis. Overall survival (OS), cancer-specific survival (CSS) and disease-free interval (DFI) were estimated. Cox residuals were evaluated using the R software version 3.5.2. Worst OS, CSS and DFI were observed in patients with tumors in advanced pathological stages (p<0.001), with the presence of perineural invasion (p<0.001) and vascular invasion (p=0.005). Results: Advanced pathological stage and the presence of a poorly differentiated tumor were independent prognostic factors for OS and CSS. However, advanced pathological stage and perineural invasion were independent predictors of a shorter OS, DFI and CSS. Conclusion: Pathological stage and perineural invasion were the most significant pathological variables in survival analysis in tongue and/or floor of the mouth SCC.

ABSTRACT

OBJECTIVE: We aimed to estimate the overall survival (OS) and conditional survival (CS) in patients diagnosed with oral and oropharyngeal squamous cell carcinoma (SCC) and to determine their survival trends. METHODS: The study included all consecutive patients treated at the A.C. Camargo Cancer Center for oral or oropharyngeal SCC between 2001 and 2012. Data were obtained from the Hospital Cancer Registry. OS and CS were analyzed using the Kaplan-Meier method to evaluate the probability of survival with Cox predictor models. RESULTS: Data of 505 oral and 380 oropharyngeal SCC patients obtained in 2001-2006 and 2007-2012 were analyzed. Most of the oral SCC (59%) and oropharyngeal SCC (90%) patients had stages III-IV SCC. The 5-year OS for patients with oral SCC was 51.7%, with no significant difference between the first and second periods. The CS rates in 2007-2012 were 65% after the first year and 86% up to the fifth year. For oropharyngeal SCC, the 5-year OS rate was 45.0% in the first period. The survival rate increased to 49.1% from 2007 to 2012, with a reduction in the risk of death (HR=0.69;0.52-09.2). The CS estimates from 2007 to 2012 were 59% after the first year and 75% up to the fifth year. CONCLUSION: Survival across the two time periods remained stable for oral SCC but showed a significant increase for oropharyngeal SCC, possibly because of improvements in the patients' response to radiotherapy, such as intensity-modulated radiation therapy, and the use of more accurate diagnostic imaging approaches.

ABSTRACT

INTRODUCCIÓN: El cáncer oral tiene una tasa de supervivencia a los cinco años de 50%, debido a que frecuentemente su diagnóstico es realizado en estadios avanzados. Por lo tanto, son necesarias nuevas ayudas diagnósticas. Actualmente, existe un número significativo de publicaciones científicas sugiriendo el uso de biomarcadores salivales para el diagnóstico de cáncer oral. Sin embargo, son desconocidas las propiedades diagnósticas de estos biomarcadores. El objetivo de esta revisión sistemática es evaluar la evidencia sobre la precisión diagnóstica de biomarcadores salivales usados en la identificación de cáncer oral y desórdenes potencialmente malignos. MÉTODOS: Este protocolo es reportado en concordancia con el Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols (PRISMA-P). Se incluirán estudios evaluando la precisión diagnóstica de biomarcadores salivales para cáncer oral y desórdenes potencialmente malignos. Estos deberán reportar sensibilidad y especificidad, y utilizar como estándar de referencia un diagnóstico histopatológico. Se realizará una búsqueda en MEDLINE, EMBASE, Cochrane Library y literatura gris. Dos autores independientemente seleccionarán los estudios y extraerán los datos. La calidad metodológica de los estudios será determinada usando The Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2). RESULTADOS ESPERADOS Y CONCLUSIÓN: Los hallazgos de esta revisión sistemática proporcionarán información acerca de la precisión diagnóstica de los biomarcadores salivales para diagnóstico de cáncer oral y desórdenes potencialmente malignos.


INTRODUCTION: Oral cancer has a 5-year survival rate of 50% because diagnosis is commonly performed at an advanced stage of the disease, so new diagnostic tools are needed. Nowadays, there is a vast number of publications suggesting the use of salivary biomarkers for oral cancer and potentially malignant disorders diagnosis, but their diagnostic accuracy is unclear. Thus, the goal of this systematic review is to evaluate the diagnostic accuracy of salivary biomarkers for oral cancer and potentially malignant disorders. METHODS: This protocol is reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols (PRISMA-P). We will include primary studies assessing the diagnostic accuracy of salivary biomarkers for oral cancer and potentially malignant disorders. Studies must report data about sensitivity and specificity; gold standard must be the histopathology diagnosis. We will search MEDLINE, EMBASE, the Cochrane Library, and gray literature. Two authors will independently select the studies and extract the data. The methodology quality of studies will be determined using the Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2). EXPECTED RESULTS AND CONCLUSION: Our findings will provide information about the diagnostic accuracy of salivary biomarkers for oral cancer and potentially malignant disorders.

ABSTRACT

Antecedentes: la cirugía reconstructiva del tercio medio de la cara es compleja y variada. La vecindad anatómica con la órbita, la base del cráneo y el seno maxilar favorece la extensión tumoral del paladar a dichas estructuras, desafiando al cirujano que debe realizar una resección con intención curativa. Objetivo: obtener conclusiones sobre la supervivencia y el intervalo libre de enfermedad en cánceres palatosinusales T4a/b, sucesivamente operados durante un período de 30 años. Material y métodos: la cirugía se extendió a la órbita en el 85,2%, al cráneo en el 8,3%, al cuello en el 18,7% y a la glándula parótida en el 7,3%. La reconstrucción de partes blandas se realizó con colgajos libres en el 32,5%, musculares en el 21,6%, de vecindad en el 20,2%, musculocutáneos en el 14,2% y con piel en el 11,3%. Resultados: se produjeron complicaciones locales y generales. Estas últimas llevaron a la muerte de 4/203 ‒2%‒ pacientes. La supervivencia global a 5 años fue del 62,5% y la libre de enfermedad, del 53%, El análisis multivariado para recurrencia fue significativo en los vírgenes de tratamiento previo y para supervivencia a favor de los escamosos frente a otras estirpes histológicas. Conclusiones: en presencia de oftalmoplejía o compromiso del contenido orbitario o de ambos, la exenteración tiene indicación absoluta. La supervivencia a 5 años resulta aceptable si se tiene en cuenta que fueron solo estadios avanzados de la enfermedad. Los tratamientos previos con que concurrieron algunos pacientes fueron negativos para su evolución. La cirugía primaria desempeñó un papel esencial en la supervivencia libre de enfermedad.


Background: the problems of reconstructive surgery for the midface are variable and can be very complex. The anatomical proximity of the midface to the orbit, base of the skull and maxillary sinuses is a challenge for the surgeon who must perform a curative resection. Objective: The aim of this presentation is to report the survival rate and disease-free interval in T4a and T4b neoplasms of the palate and paranasal sinuses consecutively resected over a 30-year period. Material and methods: Surgery was extended to the orbit in 85.2%, the skull in 8.3%, the neck in 18.7% and the parotid gland in 7.3%. Soft tissue reconstruction was performed using free flaps in 32.5%, muscle flaps in 21.6%, local flaps in 20.2%, musculocutaneous flaps in 14.7% and skin flaps in 11.3%. Results: Local and general complications were reported, and 4/203 patients (2%) died. At 5 years, overall survival was 62.5% and disease-free survival was 53%. Univariate analysis revealed that lack of previous treatment was significantly associated with recurrence and squamous cell carcinoma was a predictor of survival. Conclusions: The indication of exenteration is mandatory in the presence of ophthalmoplegia or involvement of the orbital content. Survival at 5 years is acceptable, considering the advanced stages of the disease. In some patients, previous treatments were associated with adverse outcome. Primary surgery plays an essential role for disease-free survival.

ABSTRACT

Abstract: The objective was to investigate if there is an association between the mortality rates due to oral and oropharyngeal cancer in Brazil and the expansion of access to public primary and specialized dental care services that resulted from the implementation of the National Oral Health Policy, between 2000 and 2013. The mortality data were obtained from the records of the Mortality Information System and the exposure variables were obtained from databases of the Brazilian Ministry of Health and the Brazilian Institute of Geography and Statistics. The main exposures investigated were "coverage of primary dental care" and "number of specialized dental care centers". Additional covariates included "Gini index of household income", "average number of years of study", "proportion of unemployed people" and "proportion of smokers". For the statistical analysis, a random coefficient model was used. There was a statistically significant association between the mortality rates by oral and oropharyngeal cancer with coverage by primary dental care and the number of specialized dental care centers with males. This study found that the expansion of the coverage of primary dental care and the number of specialized dental care centers are associated with the reduction of mortality rates due to oral and oropharyngeal cancer in Brazil. There is plausibility for the association found, which needs to be confirmed by implementation studies.


Resumo: O estudo teve como objetivo investigar a presença de associação entre as taxas de mortalidade por câncer de boca e de orofaringe no Brasil e a ampliação do acesso aos serviços odontológicos de atenção primária e especializados na rede pública, resultado da implementação da Política Nacional de Saúde Bucal entre 2000 e 2013. Os dados de mortalidade foram obtidos dos registros do Sistema de Informações sobre Mortalidade e as variáveis de exposição foram extraídas das bases de dados do Ministério da Saúde e do Instituto Brasileiro de Geografia e Estatística. As principais variáveis de exposição foram "cobertura por equipes de saúde bucal" e "número de centros de especialidades odontológicas". As outras variáveis foram "índice Gini de renda domiciliar", "média de anos de escolaridade", "proporção de pessoas desempregadas" e "proporção de fumantes". A análise estatística usou um modelo de coeficientes aleatórios. Houve uma associação estatisticamente significativa entre as taxas de mortalidade por câncer de boca e orofaríngeo e a cobertura por equipes de saúde bucal e o número de centros de especialidades odontológicas, entre os indivíduos do sexo masculino. O estudo mostrou que a ampliação da cobertura de atenção primária em odontologia e o número de centros de especialidades odontológicas estão associados a uma redução nas taxas de mortalidade por câncer de boca e orofaríngeo no Brasil. Há plausibilidade na associação estatística, que deve ser confirmada através de estudos de implementação.


Resumen: El objetivo fue investigar si había una asociación entre las tasas de mortalidad, debidas al cáncer oral y orofaríngeo en Brasil, y la expansión del acceso a los servicios públicos de atención primaria y servicios especializados en atención dental que fueron resultado de la implementación de la Política Nacional de Salud Oral, entre el año 2000 y el 2013. Los datos sobre mortalidad se obtuvieron de los archivos del Sistema de Informaciones sobre Mortalidad y las variables de exposición se obtuvieron de bases de datos del Ministerio de Salud de Brasil y del Instituto Brasileño de Geografía y Estadística. Las exposiciones principales investigadas fueron "cobertura de la atención primaria dental" y "número de centros especializados en atención dental". Las covariables adicionales incluyeron: "índice de Gini de ingresos por hogar", "promedio del número de años de estudio", "proporción de individuos desempleados" y "proporción de fumadores". Para el análisis estadístico, se utilizó un modelo de coeficiente aleatorio. Hubo una asociación estadísticamente significativa entre las tasas de mortalidad por cáncer oral y orofaríngeo con cobertura por parte de la atención primaria dental y el número de centros especializados en cuidado dental, con hombres. Este estudio descubrió que la expansión de la cobertura del cuidado dental primario y del número de centros especializados en cuidado dental están asociados con la reducción de las tasas de mortalidad, causadas por cáncer oral y orofaríngeo en Brasil. Es plausible por la asociación hallada, pero necesita confirmarse mediante estudios de implementación.

ABSTRACT

OBJETIVO: Describir las tendencias de la mortalidad por cáncer oral entre 2000 y 2017 por sexos en 20 países de América Latina, e identificar los efectos de las políticas implementadas para controlar de los factores de riesgo. MATERIALES Y MÉTODOS: Se realizó un estudio ecólogico que evaluó la relación entre las tasas estandarizadas por edad de mortalidad por cáncer oral según el sexo, la prevalencia de tabaquismo y consumo de alcohol y la implementación de las políticas públicas de control. RESULTADOS: Los hombres de Cuba y Brasil muestran las más altas tasas de mortalidad en la región. Los descensos más importantes se presentan en los hombres de Brasil y en las mujeres de Panamá. Son pocas las tendencias al aumento, aunque éstas se evidencian especialmente entre las mujeres. La implementación de las medidas de control de factores de riesgo, en cuanto a tabaco, alcohol, infecciones virales, programas de detección temprana y tratamiento, muestra avances desiguales entre los países. Se observó una mayor relación entre la mortalidad por cáncer oral con el consumo de tabaco en los contextos de menor implementación de las políticas, y el consumo de alcohol en los escenarios de mayor avance. CONCLUSIÓN: La mortalidad por cáncer oral afecta especialmente a los hombres de la región, lo que se puede asociar a la distribución de los factores etiológicos y avances desiguales de los países en la implementación de las medidas preventivas. Se requiere profundizar en investigación subnacional de seguimiento, y fortalecer la prevención y tratamiento con estrategias validas para cada contexto.


OBJECTIVE: To describe the trends in oral cancer mortality between 2000 and 2017 by sex in 20 countries in Latin America, and identify the effects of the policies that were implemented to control associated risk factors. MATERIALS AND METHODS: An ecological study was conducted to evaluate the relationship between age-standardized rates of oral cancer mortality by sex, the prevalence of smoking and alcohol consumption, and the implementation of public control policies. RESULTS: Men in Cuba and Brazil show the highest mortality rates in the region. The most important decreases occurred among Brazilian men and Panamanian women. There are only a few cases of increasing trends, although these are especially evident among women. The implementation of risk factor control measures, in terms of tobacco, alcohol, viral infections, early detection programs and treatment, have progressed unevenly in different countries. A strong relationship was observed between oral cancer mortality and tobacco consumption in countries with limited policy implementation; and with alcohol consumption in countries with advanced implementation. CONCLUSION: Oral cancer mortality especially affects men in the region, which can be associated with the distribution of etiological factors and unequal advances in countries in the implementation of preventive measures. It is necessary to further develop subnational follow-up research and strengthen prevention and treatment measures with valid strategies, adapted for each context.

ABSTRACT

RESUMO: Introdução: O câncer de boca e o câncer de orofaringe são doenças influenciadas por fatores socioeconômicos. O risco de desenvolver essas doenças aumenta com a idade, e a maioria dos casos ocorre em idosos, com elevadas taxas de mortalidade. O objetivo deste estudo foi analisar a influência dos índices socioeconômicos municipais nas taxas de mortalidade por câncer de boca (CB) e de orofaringe (CO) em idosos nas 645 cidades do estado de São Paulo, Brasil, nos anos de 2013 a 2015. Método: Dados secundários de óbitos foram obtidos pelo Sistema de Informações sobre Mortalidade (SIM) do Ministério da Saúde. O número de idosos e os valores da renda média per capita e do índice de desenvolvimento humano por município (IDH-M) foram obtidos a partir dos dados da Fundação SEADE. Realizou-se a análise descritiva e exploratória dos dados, seguida de modelos binomiais negativos descritos pelo procedimento PROC GENMOD e avaliados pelo critério de informação de Akaike corrigido (AICc), pelo grau de liberdade e pelo teste de Wald (α=0,05). Resultados: Cerca de 30% das cidades notificaram óbitos em 2013, 16,74% em 2014 e 18,61% em 2015. Astaxas médias de mortalidade por CB e CO foram, respectivamente, de 20,0 (± 30,9) e 10,7 (± 17,5) por 100milhabitantes. A renda média variou de R$ 434,20 a R$ 2.009,00 e o IDH-M, de 0,65 a 0,89. Houve decréscimo significativo (p < 0,05) nas taxas de mortalidade por CB e CO em idosos com o aumento dos valores das rendas médias e do IDH-M. Conclusão: As desigualdades socioeconômicas das cidades influenciam nas taxas de mortalidade por CB e CO em idosos.


ABSTRACT: Introduction: Oral and oropharyngeal cancer are diseases strongly influenced by socioeconomic factors. The risk of developing these diseases increases with age and most cases occur in the elderly, with higher mortality rates. This study aimed to analyze the influence of municipal socioeconomic indices on mortality rates for oral (OC) and oropharyngeal cancer (OPC) in elderly residents from 645 cities in the State of São Paulo, Brazil, from 2013 to 2015. Method: Secondary data on deaths were obtained in the Mortality Information System from the Brazilian Ministry of Health. The number of elderly, as well as per capita median income values and Human Development Index by municipality (HDI-M) values were obtained from data by the SEADE Foundation. Descriptiveand exploratory analysis of data was performed, followed by negative binomial models described by the Proc Genmod procedure and evaluated by the corrected AIC (Akaike Information Criterion), the likelihood level, and the Wald test (α = 0.05). Results: Around 30% of the cities notified deaths in 2013, 16.74% in 2014, and 18.61% in 2015. Founded mortality mean rates from OC and OPC were, respectively, 20.0 (± 430.9) and 10.7 (± 17.5) deaths per 100,000 inhabitants. Meanincome ranged, in local currency, from 434.2 to 2,009.00. HDI-M ranged from 0.65 to 0.89. There was a significant decrease (p<0.05) in mortality rates for OC and OPC in elderly with the increase in the cities' mean income and HDI-M values. Conclusion: Socioeconomic inequalities in the cities the on mortality rates for OC and OPC in elderly residents.

ABSTRACT

Background: Oral cancer is the 15th most common cause of cancer death in the world. In Chile, 1% of all cancer deaths are related to oral and pharyngeal cancer. Aim: To determine mortality rates for oral cancer in Chile and its regions between 2002-2012. Material and Methods: Deaths and their causes between the years 2002-2012 were obtained from the Chilean National Statistics Institute. Crude and adjusted rates by age and sex were calculated for the country and its regions. The denominator was Chilean population on June 30, 2012 and the WHO standard population. Results: In the period studied, 1,611 individuals with a mean age of 67.6 years (63% men) died because of oral cancer. The most common location of the tumor was the tongue in 27% of cases and the parotid gland in 16%. The adjusted mortality rate in Chile was 0.85 / 100,000 inhabitants (1.13 and 0.58 in men and women, respectively). The regions with the highest rates were Antofagasta (1.51), Aysén (1.22) and Magallanes (1.17). Deaths among men occurred at younger ages than women. Conclusions: Mortality rates due to oral cancer in Chile are lower than abroad. The highest rates observed in some regions may be influenced by environmental factors such as arsenic contamination in Antofagasta and the lack of specialists and specialized care centers in Aysén and Magallanes.

ABSTRACT

Abstract The objective of this study was to determine of oral and oropharynx cancer mortality rate and the results were analyzed by applying the Spatial Analysis of Empirical Bayesian Model. To this end, we used the information contained in the International Classification of Diseases (ICD-10), Chapter II, Category C00 to C14 and Brazilian Mortality Information System (SIM) of Minas Gerais State. Descriptive statistics were observed and the gross rate of mortality was calculated for each municipality. Then Empirical Bayesian estimators were applied. The results showed that, in 2012, in the state of Minas Gerais, were registered 769 deaths of patients with cancer of oral and oropharynx, with 607 (78.96%) men and 162 (21.04%) women. There was a wide variation in spatial distribution of crude mortality rate and were identified agglomeration in the South, Central and North more accurately by Bayesian Estimator Global and Local Model. Through Bayesian models was possible to map the spatial clustering of deaths from oral cancer more accurately, and with the application of the method of spatial epidemiology, it was possible to obtain more accurate results and provide subsidies to reduce the number of deaths from this type of cancer.


Resumo O objetivo deste estudo foi determinar a taxa de mortalidade por câncer de boca e aplicar o Modelo Bayesiano Empírico e a Análise Espacial para suavizar a taxa bruta de mortalidade por câncer de boca e orofaringe. Foi usado o Capítulo II da Classificação Internacional de Doenças (CID-10) para Categorias C00 a C14. Os dados foram extraídos do Sistema de Informações sobre Mortalidade do Brasil (SIM) do Estado de Minas Gerais. As estatísticas descritivas e as taxas brutas de mortalidade foram calculadas para cada município. Posteriormente, foram aplicados os estimadores Bayesianos Empíricos. Em 2012, em Minas Gerais, foram registradas 769 mortes para o câncer de boca e orofaringe, dos quais 607 (78,96%) eram homens e 162 (21,04%) mulheres. Houve uma grande variação na distribuição espacial da taxa de mortalidade bruta. Foi possível identificar aglomeração nas regiões Sul, Central e Norte com maior precisão pelo Estimador Bayesiano Modelo Global e Local. Através dos Modelos Bayesian foi possível mapear aglomeração espacial de mortes por câncer de boca e orofaringe com maior precisão. Assim, pela epidemiologia espacial foi possível obter resultados mais precisos e fornecer subsídios para ações para reduzir a mortalidade por este tipo de câncer.

ABSTRACT

ABSTRACT OBJECTIVE To analyze the trend of oral and pharyngeal cancer mortality rates in the period of 2002 to 2013 in Brazil according to sex, anatomical site, and macroregion of the country. METHODS The mortality data were obtained from the Mortality Information System and the population data were obtained from the Brazilian Institute of Geography and Statistics. The trend of the rates standardized by sex and age was calculated using the Prais-Winsten estimation, and we obtained the annual percentage change and the respective 95% confidence intervals, analyzed according to sex, macroregion, and anatomical site. RESULTS The average coefficient of oral cancer mortality was 1.87 per 100,000 inhabitants and it remained stable during the study period. The coefficient of pharyngeal cancer mortality was 2.04 per 100,000 inhabitants and it presented an annual percentage change of -2.6%. Approximately eight in every 10 deaths occurred among men. There was an increase in the rates of oral cancer in the Northeast region (annual percentage change of 6.9%) and a decrease in the Southeast region (annual percentage change of -2.9%). Pharyngeal cancer mortality decreased in the Southeast and South regions with annual percentage change of -4.8% and -5.1% respectively. Cancer mortality for tonsil, other major salivary glands, hypopharynx, and other and unspecified parts of mouth and pharynx showed a decreasing trend while the other sites presented stability. CONCLUSIONS Pharyngeal cancer mortality decreased in the period of 2002 to 2013. Oral cancer increased only in the Northeast region. Mortality for tonsil cancer, other major salivary glands, hypopharynx, and other and ill-defined sites in the lip, oral cavity, and pharynx decreased.


RESUMO OBJETIVO Analisar a tendência das taxas de mortalidade por câncer de boca e de faringe no período de 2002-2013 no Brasil segundo sexo, sítio anatômico e macrorregião do país. MÉTODOS Os dados sobre mortalidade foram obtidos junto ao Sistema de Informações sobre Mortalidade e os dados das populações foram obtidos junto ao Instituto Brasileiro de Geografia e Estatística. A tendência das taxas padronizadas por sexo e faixa etária foi calculada por regressão de Prais-Winstein, obtendo a sua variação percentual anual e os respectivos intervalos de confiança de 95%, analisados segundo sexo, macrorregião e sítio anatômico. RESULTADOS O coeficiente médio de mortalidade por câncer de boca foi de 1,87/100.000 habitantes e permaneceu estável durante o período estudado. O coeficiente de mortalidade por câncer de faringe foi de 2,04/100.000 habitantes e apresentou variação percentual anual de -2,6%. Aproximadamente oito em cada 10 óbitos ocorreram entre homens. Observou-se aumento nas taxas por câncer de boca na região Nordeste (variação percentual anual de 6,9%) e diminuição na região Sudeste (variação percentual anual -2,9%). Mortalidade por câncer de faringe diminuiu nas regiões Sudeste e Sul com variação percentual anual de -4,8% e -5,1% respectivamente. Mortalidade por câncer de amígdala, outras glândulas salivares maiores, hipofaringe e outras partes não especificas de boca e faringe, apresentaram tendência de declínio enquanto os demais sítios apresentaram estabilidade. CONCLUSÕES A mortalidade por câncer de faringe apresentou diminuição no período 2002-2013. O câncer de boca apresentou aumento só na região Nordeste. Mortalidade por câncer de amígdala, outras glândulas maiores, hipofaringe e outras localizações mal definidas de lábio, cavidade oral e faringe mostraram declínio.

ABSTRACT

ABSTRACT Objective To evaluate the epidemiological profile and survival rate of oral and oropharyngeal cancer patients seen at a university hospital. Methods A cross-sectional study was carried out by means of the pathological reports of patients with oral and oropharyngeal cancer, seen at a university hospital of the Southern Region, between January 2004 and December 2014. Information was collected on patients and tumors. The mortality rate was gathered from the patient death registry in the Mortality Information System. Data were analyzed using the Kaplan-Meier survival curve and the log-rank test to compare variables. Results The 5- and 10-year survival rates were 42% and 38%, respectively. The anatomical location had a significant association with survival rate (p=0.001), with the rates were better in the lips (p=0.04), and worse in the oropharynx (p=0.03). There were no statistically significant differences between survival rates according to age, sex, ethnicity, schooling level and histologic grade. Conclusion The survival rates of oral and oropharyngeal cancer were and associated with the anatomical site of the tumor.


RESUMO Objetivo Avaliar o perfil epidemiológico e a taxa de sobrevida do câncer de boca e orofaringe de pacientes atendidos em um hospital universitário. Métodos Foi realizado um estudo transversal por meio dos laudos anatomopatológicos dos pacientes com câncer de boca e orofaringe atendidos em um hospital universitário, na Região Sul, entre janeiro de 2004 a dezembro de 2014. A partir destes laudos, foram coletadas informações sobre o paciente e o tumor. A taxa de mortalidade foi obtida do registro de óbitos dos pacientes no Sistema de Informações sobre Mortalidade. Os dados foram analisados utilizando a curva de sobrevida pelo método de Kaplan-Meier e o teste de log-rank para a comparação das variáveis. Resultados As taxas de sobrevida em 5 e 10 anos foram 42% e 38%, respectivamente. A localização anatômica apresentou associação significativa com a taxa de sobrevida (p=0,001), sendo que, em lábio, os índices foram melhores (p=0,04) e, em orofaringe, piores (p=0,03). Não houve diferenças estatisticamente significantes entre as taxas de sobrevida de acordo com idade, sexo, etnia, nível educacional e grau histológico. Conclusão As taxas de sobrevida do câncer de boca e orofaringe foram baixas e associadas à localização anatômica do tumor.

ABSTRACT

Introducción: la predicción es una de las actividades asistenciales y de investigación con mayor auge actualmente. El desarrollo alcanzado por los servicios estomatológicos en Cuba ha contribuido a la disminución de la incidencia del cáncer bucal, pero resulta preocupante que cada año esta enfermad se diagnostique en un grupo considerable de personas. Desde este punto de vista, el análisis de series temporales es de vital importancia en la vigilancia y predicción de las enfermedades. Objetivo: analizar el comportamiento de las series de incidencia y mortalidad del cáncer bucal para la generación de pronósticos, con un horizonte de predicción de tres años, en la provincia Ciego de Ávila. Métodos: se realizó un estudio descriptivo longitudinal retrospectivo de series temporales. Se analizaron las series temporales del cáncer bucal, con frecuencia de incidencia anual durante 8 años (2007-2014) y mortalidad durante 12 años (2003-2014). Para la obtención del pronóstico se emplearon métodos sencillos, rápidos y efectivos: el método de los mínimos cuadrados y el alisamiento o suavizamiento exponencial con dos parámetros, que suaviza las oscilaciones locales y permite apreciar la tendencia de la serie. Se empleó el programa EVIEWS 4.1. Resultados: en cuanto a la incidencia se pronosticó una estimación puntual de aproximadamente 73 casos anuales e intervalos de predicción que pueden oscilar de 59 a 87 para los próximos años. Con respecto a la mortalidad se obtuvieron intervalos de predición muy estrechos que oscilan entre 26 y 50, con una estimación puntual de 37 fallecidos por año aproximadamente. Conclusiones: el comportamiento de la serie de incidencia y mortalidad del cáncer bucal en la provincia es creciente, por lo que se estima un incremento para los próximos tres años(AU)


Introduction: prediction is a major practice in health care and research nowadays. The development achieved by dental services in Cuba has contributed to reduce the incidence of oral cancer, but it is still a reason for concern that a large number of people are diagnosed with this condition every year. In this context, time series analysis is crucially important for disease surveillance and prediction. Objective: analyze the behavior of oral cancer incidence and mortality series to generate a prognosis with a three-year prediction horizon in the province of Ciego de Avila. Methods: a time-series retrospective longitudinal descriptive study was conducted. An analysis was performed of the oral cancer time series, based on an annual incidence frequency for eight years (2007-2014) and a mortality rate for 12 years (2003-2014). Simple, fast, effective methods were used to obtain the prognosis: the least squares method and two-parameter exponential smoothing, which smooths local oscillations making it possible to appreciate the trend in the series. Use was made of the software EVIEWS 4.1. Results: regarding incidence, a prognosis was made of a point estimation of approximately 73 cases per year, with prediction intervals ranging between 59 and 87 for the next years. Regarding mortality, very narrow prediction intervals were obtained which range between 26 and 50, with a point estimation of approximately 37 deaths per year. Conclusions: behavior of the oral cancer incidence and mortality series in the province is on the increase, and it is estimated that it will continue to grow in the next three years(AU)

ABSTRACT

Aim: To investigate the spatial-temporal distribution of mortality from oral cancer in Minas Gerais between 1996 and 2012. Methods: The analysis of the growth trend rates of the series was made by Moving Average. Results: In the period there were 8.675 deaths from mouth cancer and these were identified in all the regions of the state. Being, 6,974 (80,4%) men and 1,701 (19,6%) women. Regarding the crude rate, we observed a tendency of growing of mortality from this cancer type. This phenomenon was also observed when executed the weighting by sex, especially for males and over 60 years old. Was rejected the null hypothesis of stationary of mortality series for oral cancer in Minas Gerais during the period. Conclusion: Moving Average weighted by age and gender allowed to observe an increase in the mortality rate in all age groups and for both sexes especially men and older than 60 years.

ABSTRACT

Abstract The aim of this study was to identify the expression of Ki-67 and MCM3 in oral squamous cell carcinoma (OSCC) as well as to address the correlation with patient survival and clinical features. Samples were collected from 51 patients with OSCC who presented for follow-up. Immunohistochemical expression of Ki-67 and MCM3 in all groups was performed. The scoring system was previous published by Tsurutani in 2005. We used Kappa index to evaluate observers agreement degree. The associations between protein expression and clinical variables were examined for statistical significance using the chi-squared test. The overall survival rates were estimated by the Kaplan-Meier method and the relationship between protein expression and survival was compared using the log-rank test (p < 0.05). The overall survival time for a patient with positive immunostaining for Ki-67 is shorter than for a patient with negative immunostaining, (log-rank test, p = 0.00882). Patients with tumor size T3 and T4 showed a statistically significant relationship with Ki-67 immunoexpression (log-rank test, p = 0.0174). The relationship between Ki-67 expression and the relation between age, gender, smoking, tumor site, lymph node metastasis and disease stage was not significant. The examiners agreement degree by Kappa presented p value < 0.05. There was not a significant correlation when we evaluated MCM3 expression regarding clinical characteristics and survival rate. From these results, the present study suggests that positive Ki-67 expression found in OSCC patients may contribute to predict the survival in OSCC samples, as well as the relation between the protein and the tumor size.

ABSTRACT

Introducción: El carcinoma espinocelular (CEC) es una neoplasia maligna derivada del epitelio plano estratificado. Hoy en día ha adquirido mayor importancia debido a que es el cáncer oral más frecuente y su sobrevida sobre los 5 años se ha mantenido baja. Objetivo: Generar información que oriente a odontólogos y médicos en la detección y manejo oportuno del CEC oral analizando la sobrevida según características demográficas y clínicas de pacientes con esta enfermedad atendidos en el CRS Cordillera Oriente. Materiales y métodos: Estudio descriptivo, retrospectivo de tipo serie de casos. La muestra correspondió al total de pacientes diagnosticados con CEC oral en el CRS Cordillera Oriente entre enero de 2001 y mayo de 2015. Para el estudio epidemiológico de la muestra se utilizó estadística descriptiva y para el análisis de la sobrevida se utilizó el método de Kaplan Meier. Resultados: La mayor parte de la muestra fueron hombres (8/13) y mayores de 60 años (7/13). La edad promedio fue de 63,6 años. La presentación más común fue la úlcera crónica (6/13) y la localización más frecuente, el labio (4/13). En su mayoría fueron tumores bien diferenciados (9/13), un estado del tumor primario en etapa pT1 o pT2 (7/8) y ausencia de metástasis en nodos regionales (6/9). Se encontró una distribución homogénea respecto a la etapa TNM. La sobrevida general a los 5 años fue de 57,9%. La sobrevida más baja a los 5 años se presentó en pacientes de sexo femenino, menores de 45 años, fumadores, con presentación de masa exofítica, con tumores de menor grado de diferenciación histológica, con un estado del tumor primario avanzado, con presencia de metástasis en nodos regionales y que se encontraban en una etapa TNM avanzada. Conclusiones: La prevalencia de CEC oral en este centro es baja, sin embargo, es de relevancia dado la reducida sobrevida sobre los 5 años. Esto pone de manifiesto la necesidad de un diagnóstico y tratamiento oportunos. La información presentada es de utilidad para la identificación de la población en riesgo de CEC oral, pudiendo ayudar en el desarrollo de programas de tamizaje. El limitado número de casos puede explicar las diferencias observadas respecto a la literatura nacional e internacional lo que genera la necesidad de realizar nuevos estudios.


Introduction: Squamous cell carcinoma (SCC) is a malignant neoplasm derived from stratified squamous epithelium. Today it has become more important because it is the most common oral cancer and its survival over five years has remained low. Aim: Produce information to guide dentist and physicians in the prompt detection and management of oral SCC through the analysis of survival according to demographic and clinical characteristics of patients diagnosed at the CRS Cordillera Oriente. Methods: We perform a descriptive, retrospective study of case series. Patients diagnosed with oral SCC at the CRS Cordillera Oriente, between January 2001 and May 2015 were selected. We used descriptive statistics for the epidemiological study sample and the Kaplan Meier method for the survival analysis. Results: The study population was mainly men gender (8/13) and over 60 years (7/13). The average age was 63,6 years. The most common presentation was chronic ulcer (6/13) and the most common site, the lip (4/13). Most of the sample had a well differentiated tumor (9/13), a primary tumor stage pT1 or pT2 (7/8) and absence of metastases in regional nodes (6/9). A homogeneous distribution with respect to the TNM stage was found. The overall survival at 5years was 57,9%, the lowest rates were in the female gender, group under 45 years, smokers, exophytic mass, poorly differentiated tumor, advanced primary tumor, presence of regional metastases in nodes and advanced TNM stage. Conclusions: The prevalence of oral SCC in this center is low, however, it is relevant given the reduced survival over 5 years. This highlights the need for early diagnosis and treatment. The information presented is useful for identifying population at risk or oral SCC, and may assist in the development of screening programs. The limited number of cases may explain the observed differences regarding the national and international literature wich generates the need for further studies.
