ABSTRACT

O objetivo deste estudo foi avaliar o conhecimento de pacientes do Centro Universitário da Serra Gaúcha acerca do câncer oral. Foram aplicados questionários para idosos (n=60) de ambos os gêneros, diferentes etnias e graus de escolaridade. A análise dos dados foi realizada por meio do teste qui-quadrado com nível de confiança de 95%. Não houve relação estatisticamente significativa (p>0,05) entre gênero, estado civil e escolaridade. A presença de lesões bucais, ausência de dentes, visitas frequentes ao dentista, e uso de bebida alcoólica e tabagismo não influenciaram quanto ao conhecimento acerca do câncer bucal. Embora a maioria dos pacientes (85%) já tenha ouvido falar em câncer bucal, apenas a minoria relatou saber se prevenir (23%) e possuir o hábito de examinar a boca em casa (35%). Além disso, apesar de 55% dos pacientes visitarem regularmente o dentista, apenas 28,3% relatou ter recebido informações sobre o câncer bucal. Pôde-se concluir que mesmo sabendo da existência do câncer bucal, a população idosa não possui informações suficientes para o correto diagnóstico e prevenção da doença, sendo necessário melhorias nas orientações fornecidas pelos profissionais da área da saúde com relação a este tema(AU)


The aim of this study was to evaluate the knowledge of patients at Serra Gaucha University Center about oral cancer. Questionnaires were applied to the elderly (n = 60) of both genders, different ethnicities and educational levels. Data analysis was performed using the chi-square test with a 95% confidence level. There was no statistically significant relationship (p> 0.05) between gender, marital status and education. The presence of oral lesions, absence of teeth, frequent visits to the dentist, and the use of alcohol and smoking did not influence the knowledge about oral cancer. Although most patients (85%) have heard of oral cancer, only a minority reported knowing whether to prevent it (23%) and having the habit of examining their mouth at home (35%). In addition, although 55% of patients regularly visit the dentist, only 28.3% reported receiving oral cancer information. It can be concluded that even knowing the existence of oral cancer, the elderly population does not have enough information for the correct diagnosis and prevention of the disease, being necessary improvements in the guidance provided by health professionals regarding this theme(AU)

ABSTRACT

Introducción: El Cáncer Bucal es una enfermedad de importancia en Salud Pública. En Panamá, se desconoce la incidencia y prevalencia de la enfermedad y no se dispone de información por tipo de patología, lesión, localización, ni estudios de conocimientos, ac­ titudes y prácticas, relacionados a los factores de riesgo. Objetivo General: analizar los conocimientos, actitudes y prácticas de prevención de Cáncer Bucal en la población mayor de 15 años. Materiales y Método: estudio descriptivo transversal, realizado en las Regiones Sanitarias de San Miguelito, Metropolitana y Panamá Oeste. Se realizó un muestreo por conveniencia en 42 instalaciones de salud del primer nivel de atención, a la población que acudió al servicio odontológico durante cuatro meses. Se aplicó una encuesta de Conocimiento, Actitudes y Prácticas de prevención de factores de riesgo al cáncer bucal, considerando variables de estilo de vida. Para el análisis estadístico, se utilizaron los programas Epi Info versión 7.2 y XLSTAT 2019 y presentados los datos en medidas paramétricas y no paramétricas. Resultados: se encuestó un total de 3,832 personas mayores de 15 años. La mayor proporción fueron mujeres en edades de 25 y 34 años. En relación al conocimiento, el 81% desconoce los factores de riesgo de cáncer bucal y según la actitud, el 63% no asiste al control odontológico periódicamente. Las prácticas reflejaron hábitos relaciona­ dos al consumo de tabaco y alcohol. Conclusión: La población mayor de 15 años del estudio, desconoce los factores de riesgo del cáncer bucal y manifiesta limitada actitud de práctica preventiva.


Introduction: Oral Cancer is an importance disease in Public Health. In Panama, the in­ cidence and prevalence of the disease is unknown and there is no information available by type of pathology, injury, location, or studies of knowledge, attitudes and practices re­ lated to risk factors. General Objective: to analyze the knowledge, attitudes and practi­ ces of prevention of Oral Cancer in the population over 15 years old. Materials and Methods: cross­sectional descriptive study, carried out in San Miguelito, Metropolitan and Panamá Oeste Health Regions. Sampling was carried out for convenience in 42 health facilities of the first level of health care, to the population that attended the dental service during four months. A survey of Knowledge, Attitudes and Practices of preven­ tion of risk factors to oral cancer was applied, considering Lifestyle variables. For the statistical analysis, the Epi Info version 7.2 and XLSTAT 2019 programs were used and the data presented in parametric and non­parametric measurements. Results: a total of 3,832 people over 15 years of age were surveyed. The highest propor­ tions were women between the ages of 25 and 34. In relation to knowledge, 81% do not know the risk factors for oral cancer and according to the attitude, 63%, do not attend pe­ riodically to a dental control. The practices reflected habits related to consumption of to­ bacco and alcohol. Conclusion: The population over 15 years old of the study ignores the risk factors of oral cancer and manifests a limited attitude of preventive practice.

ABSTRACT

Objetivo: Avaliar a internação hospitalar por câncer de boca e faringe no Brasil no período de 2008 a 2017. Métodos: Estudo das internações por estas neoplasias registradas no Sistema de Informação Hospitalar disponíveis no DATASUS/MS entre 2008 e 2017. Resultados: Foram registradas 263.556 mil internações por câncer de boca e faringe. O Sudeste apresentou a maior frequência de casos (44,3%). A maior taxa de internação ocorreu no Sul (19,6/100 mil habitantes). As maiores taxas de letalidade encontradas foram no Norte (12,7%) e Sudeste (12,3%). Houve um predomínio de internações em regime privado (53,5%) e em caráter de urgência no Brasil (53,5%). A média de permanência hospitalar foi de 6,4 dias. A taxa de letalidade em caráter de urgência foi maior do que em caráter eletivo. A taxa de internação apresentou tendência decrescente e a taxa de letalidade hospitalar, tendência de incremento de 0,2% a cada ano. A análise de índice de desenvolvimento humano médio e taxa de internação mostrou correlação moderada positiva entre essas variáveis e as regiões do país. Houve maior custo médio em reais por internação hospitalar em caráter eletivo e a região Centro-Oeste obteve maior média de custo financeiro (por guia autorizada) nesta modalidade. Conclusão: Observa-se um elevado número de internações por estes tipos de câncer no Brasil, além de um acentuado custo e alta média de permanência hospitalar, sendo variável entre as regiões do país.


Aim: To analyze hospital admission for oral and pharyngeal cancer in Brazil and regions from 2008 to 2017. Methods: This study analyzed the hospitalizations for this neoplasm registered in the Hospital Information System available in DATASUS/MS between 2008 and 2017. Results: A total of 263,556 hospitalizations were registered. The Southeast presented the highest frequency of cases (44.3%). The highest hospitalization rate occurred in the South (19.6/100 thousand). The highest rates of lethality were found in the North (12.7%) and Southeast (12.3%). There was a predominance of hospitalizations in the private care (53.5%) and emergency care (53.5%) sectors in Brazil. The mean hospital stay was 6.4 days. The case fatality rate was higher than the elective rate. The hospitalization rate declined, and the hospital lethality rate showed a tendency toward an increase of 0.2% per year. The correlation analysis of the average human development index and the hospitalization rates were moderately positive between the variables and the regions of the country. There was a higher average cost in reais for hospital admission on an elective basis, and the Mid-West region obtained a higher average financial cost (per authorized guide) in this modality. Conclusion: It was possible to verify a high number of hospitalizations for these types of cancer in Brazil, in addition to a high cost and average hospital stay, which tend to vary throughout the country.

ABSTRACT

Objective: κ-carrageenan is a food stabilizer agent which has an antiproliferative effect, while vitamin D is a prohormone acts on the nuclear receptor and has a cytotoxic against cancer. This study aimed to show the synergistic effect of using topical κ-carrageenan and oral administration of the vitamin D on the 7, 12-dimethylbenz[a] anthracene (DMBA)-induced oral cancer. Material and Methods: fifty four male albino rats were randomly divided into seven groups: Acetonetreated served as control (Group I), vitamin D (5000UI)-treated (Group II), κ-carrageenan (1%)- treated (Group III), DMBA (0.5%)-treated (Group IV), Acetone, κ-carrageenan and DMBA were administered topically on both cheeks and palate, five times weekly for 12 weeks, while the vitamin D was administered orally twice weekly for 12 weeks. Groups V, VI, and VII were animals treated with vitamin D, κ-carrageenan, and both vitamin D and κ-carrageenan for 8 weeks after induction of oral cancer. At the end of the study, blood samples were obtained by cardiac puncture for determination of TNF-α and EGFR. Results: In the groups III and IV, serum EGFR showed significant low levels compared with Group I. In the Group VII, serum EGFR showed a significantly (p=0.014) low level compared with Group IV (614.3±69.7 pg/ml versus 882.4±45.6 pg/ml, respectively). Higher percentages of high levels of TNF-α were observed in the Groups VI and VII, while a lower percentage of EGFR was observed in the Group VI. Conclusion: both κ-carrageenan and vitamin D have antiproliferative effect against DMBAinducing oral cancer by increasing the levels of TNF-α and suppressing the signaling pathway of EGFR. Concomitant using κ-carrageenan and vitamin D reduces the antiproliferative effect of each other.(AU)


Objetivo: κ-carragenina é um agente estabilizador de alimentos que tem efeito um antiproliferativo, enquanto a vitamina D é um pró-hormônio que atua sobre o receptor nuclear e possui efeito citotóxico contra o câncer. Este estudo teve como objetivo mostrar o efeito sinérgico do uso de κ-carragenina tópica e administração oral da vitamina D no câncer de boca induzido por 7, 12-dimetilbenz[a]antraceno (DMBA). Material e Métodos: cinquenta e quatro ratos albinos machos foram divididos aleatoriamente em sete grupos: tratado com acetona como controle (Grupo I), tratado com vitamina D (5000UI) (grupo II), tratado com κ-carragenina (1%) (grupo III), DMBA (0,5%) tratado (Grupo IV), acetona, κ-carragenina e DMBA foram administrados topicamente nas bochechas e no palato, cinco vezes por semana durante 12 semanas, enquanto a vitamina D foi administrada por via oral duas vezes por semana durante 12 semanas. Os grupos V, VI e VII foram animais tratados com vitamina D, κ-carragenina e No final do estudo, foram obtidas amostras de sangue por punção cardíaca para determinação do TNF-α e EGFR. Resultados: Nos grupos III e IV, o EGFR sérico mostrou níveis baixos significativos em comparação com o Grupo I. No grupo VII, o EGFR sérico mostrou um nível significativamente baixo (p = 0,014) em comparação com o Grupo IV (614,3 ± 69,7 pg / ml versus 882,4 ± 45,6 pg / ml, respectivamente). Maiores porcentagens de TNF-α foram observadas nos Grupos VI e VII, enquanto uma menor porcentagem de EGFR foi observada no Grupo VI. Conclusão: Tanto a κ-carragenina quanto a vitamina D têm efeito antiproliferativo contra o câncer de boca induzido por DMBA aumentando os níveis de TNF-α e suprimindo a via de sinalização do EGFR. O uso concomitante de κ-carragenina e a vitamina D reduz o efeito antiproliferativo um do outro (AU)

ABSTRACT

Benign oral vascular lesions are anomalies characterized by the blood vessels proliferation or malformation and the treatment with the sclerosing agent ethanolamine oleate acts irrigating the vessel producing a sterile inflammatory response. The objective of this study was to report and discuss the results from treatment of benign oral vascular lesions with non-diluted ethanolamine oleate through the analysis of clinical records. The sample was composed by the selection of twenty-six patients (12 male and 14 female), with oral vascular malformations. All lesions were treated with intralesional injections of undiluted ethanolamine oleate. These patients attended in Oral Medicine outpatient clinic of the Federal University of Paraná between the years of 2011 to 2015. The average age was 60.65 years, with a higher prevalence for women. The majority of the individuals had one lesion and its location was mostly in the lower lip. The main complaint was about a physical discomfort. The lesions had the average size of 6.52 mm and received a median number of 2.32 applications. Only one patient reported feeling pain in the postoperative week. In most cases the resolution of the lesion was considered partial. Follow-up was obtained up to one month after the end of treatment. The sclerotherapy with undiluted ethanolamine oleate shows acceptable results in the treatment of small benign oral vascular lesions with a few minor side effects.


Las lesiones vasculares orales benignas son anomalías caracterizadas por la proliferación o malformación de los vasos sanguíneos y el tratamiento con el agente esclerosante etanolamina oleato actúa irrigando el vaso produciendo una respuesta inflamatoria estéril. El objetivo de este estudio fue informar y discutir los resultados del tratamiento de lesiones vasculares orales benignas con oleato de etanolamina no diluido a través del análisis de historias clínicas. La muestra estuvo compuesta por la selección de veintiséis pacientes (12 hombres y 14 mujeres), con malformaciones vasculares orales. Todas las lesiones fueron tratadas con inyecciones intralesionales de oleato de etanolamina sin diluir. Estos pacientes acudieron a la clínica ambulatoria de Medicina Oral de la Universidad Federal de Paraná entre los años 2011 a 2015. La edad promedio fue de 60,65 años, con una mayor prevalencia para las mujeres. La mayoría de los individuos tenían una lesión y su ubicación era principalmente en el labio inferior. La queja principal era sobre una molestia física. Las lesiones tenían un tamaño promedio de 6,52 mm y recibieron una mediana de 2,32 aplicaciones. Solo un paciente informó haber sentido dolor en la semana postoperatoria. En la mayoría de los casos, la resolución de la lesión se consideró parcial. El seguimiento se obtuvo hasta un mes después del final del tratamiento. La escleroterapia con oleato de etanolamina sin diluir muestra resultados aceptables en el tratamiento de pequeñas lesiones vasculares orales benignas con algunos efectos secundarios menores.

ABSTRACT

Objetivo:Este trabalho analisou os casos de neoplasias orofaciais em crianças e adolescentes, diagnosticadas pelo Laboratório de Patologia Oral da Universidade Federal de Pernambuco no período de março de 2000 a março de 2019. Métodos: Tratou-se de um estudo retrospectivo das neoplasias mais prevalentes diagnosticada no serviço. Os dados foram tabulados e analisados através do programa Statistical Package for the Social Sciences(SPSS) na versão 24.0. Resultados:Dos 6.766 casos diagnosticados, 101 foram de neoplasias, destes 52,5% foram no sexo feminino. A média de idade entre os pacientes foi de 12,6 anos. Em relação ao tipo de biópsia, a excisional foi mais prevalente e em 71,3% dos casos os diagnósticos histopatológicos confirmaram as hipóteses diagnósticas clínicas. A neoplasia benigna não odontogênica mais comum foi o papiloma oral com 30 casos (29,7%). Entre os tumores benignos de origem odontogênica, os odontomas foram os mais prevalentes com 16 casos (15,8%). Foram diagnosticados apenas dois tipos de neoplasias malignas: o carcinoma adenoide cístico e o leiomiossarcoma. Conclusão:Levantamentos epidemiológicos de lesões orofaciais são importantes para determinar a sua prevalência, além de contribuir com a determinação das características na população estudada, fornecendo ao cirurgião-dentista uma base sólida para o diagnóstico e manejo clínico das neoplasias nesses indivíduos.


Aim:To analyze the cases of orofacial neoplasms in children and adolescents, diagnosed by the Oral Pathology Laboratory of the Federal University of Pernambuco from March 2000 to March 2019. Methods: Treatment of a retrospective study of the most prevalent neoplasms diagnosed at the laboratory. Data were tabulated and analyzed using the Statistical Package for Social Sciences (SPSS), version 24.0. Results:Of the 6,766 cases diagnosed, 101 were neoplasms, 52.5% of these were not female. The average age among the patients was 12.6 years. Regarding the type of biopsy, tooth extractions were more prevalent, and in 71.3% of the cases, the histopathological diagnoses confirmed the clinical diagnostic hypotheses. The most common non-odontogenic benign neoplasm was the oral papilloma, found in 30 cases (29.7%). Among the benign tumors of odontogenic origin, the odontomas were the most prevalent in 16 cases (15.8%). Only two types of malignant neoplasms were diagnosed: adenoid cystic carcinoma and leiomyosarcoma. Conclusion:Epidemiological surveys of orofacial lesions are important to determine their prevalence and aid in defining the characteristics in the studied population, providing the dentist with a continuous basis for the diagnosis and clinical treatment of neoplasms in these individuals.

ABSTRACT

Introduction:Socio-spatial measures are largely used in health research, but it is still unusual in oral cancer investigation. Objective: This study aims to describe the sociodemographic and clinical features of oral cancer and analyze the spatial distribution of the disease in relation to the neighborhood socioeconomic status including availability of health care centers.Method: Sociodemographic, clinical and histopathologic data were collected from patients treated from 2005 to 2015. Descriptive data analyses of all variables were performed. The spatial analysis was carried out through the program R. Geographic distribution of patients' home addresses was analyzed using Ripley's K function and Kernel maps. The socio-spatial vulnerability was defined by household income and home adequacy. Results: Of the 127 patients included, the majority were males (76.4%), Caucasian or Brown (82.7%), married (35.4%), with low educational level (71.6%) and mean age of 59.5 years. Cases were distributed in clusters characterized by lower median income and inadequate sanitary conditions. Primary health care centers were homogeneously distributed throughout the city. Conclusion: These oral cancer cases are concentrated in regions under relatively low socioeconomic conditions, and despite the homogeneous distribution of primary health care centers, it is not enough to promote access for patients and oral cancer remains being diagnosed late


Introdução: Medidas socioespaciais são amplamente utilizadas na pesquisa em saúde, mas ainda pouco exploradas em relação ao câncer de boca.Objetivo: Descrever as características sociodemográficas e clínicas do câncer de boca e analisar a distribuição espacial da doença em relação ao status socioeconômico do bairro, incluindo a disponibilidade de centros de saúde. Método: Foram coletados dados sociodemográficos, clínicos e histopatológicos dos pacientes atendidos no período de 2005 a 2015. Foram realizadas análises descritivas dos dados de todas as variáveis. A análise espacial foi realizada por meio do programa R. A distribuição geográfica dos endereços residenciais dos pacientes foi analisada usando a função K de Ripley e mapas de Kernel. A vulnerabilidade socioespacial foi definida pela renda familiar e adequação do domicílio. Resultados: Dos 127 pacientes incluídos, a maioria era do sexo masculino (76,4%), branca ou parda (82,7%), casada (35,4%), com baixa escolaridade (71,6%) e idade média de 59,5 anos. Os casos foram distribuídos em grupos caracterizados por menor renda mediana e condições sanitárias inadequadas. Conclusão: Os casos de câncer oral estão concentrados em regiões de baixa condição econômica. Embora os centros de atenção primária à saúde tenham sido homogeneamente distribuídos por toda a cidade, isso não é suficiente para promover o acesso dos pacientes e o câncer de boca continua sendo diagnosticado tardiamente.


Introducción: Las medidas socioespaciales son ampliamente utilizadas en las investigaciones relacionadas con la salud, sin embargo, existen pocos estudios en relación con el cáncer oral. Objetivo: Describir las características sociodemográficas y clínicas del cáncer oral y analizar la distribución espacial de la enfermedad en relación con el estado socioeconómico del vecindario, la disponibilidad de centros de salud. Método: Se recogieron datos sociodemográficos, clínicos e histopatológicos de pacientes tratados entre 2005 y 2015. Se realizaron análisis descriptivos de los datos para todas las variables. El análisis espacial se realizó utilizando el programa R. La distribución geográfica de las direcciones de los hogares de los pacientes se analizó utilizando la función K de Ripley y los mapas de Kernel. La vulnerabilidad socioespacial se definió por el ingreso familiar y la adecuación del hogar. Resultados: De los 127 pacientes incluidos, la mayoría eran hombres (76.4%), blancos o morenos (82.7%), casados (35.4%), con baja educación (71.6%) y edad promedio 59,5 años. Los casos se distribuyeron en grupos caracterizados por ingresos medios más bajos y condiciones sanitarias inadecuadas. Los centros de atención primaria de salud se distribuyeron de manera homogénea en toda la ciudad. Conclusión: Estos casos de cáncer están concentrados en regiones con condiciones socioeconómicas relativamente mas bajas. A pesar de la distribución de la atención primaria, esta no suficiente para promover el acceso de los pacientes a ella y su diagnóstico continúa siendo tardío.

ABSTRACT

Introdução: O carcinoma de células escamosas é o tumor de maior importância na região de cabeça e pescoço, em razão da sua incidência e mortalidade. Sabe-se que fatores como consumo de álcool estão relacionados à diminuição da sobrevida de tumores tanto estimulando a progressão tumoral como causando comorbidades importantes, sendo um fator relevante para estudo. Objetivo: Avaliar a influência do histórico de álcool em características clinicoprognósticas de pacientes com carcinoma de células escamosas de boca e orofaringe (CCEBO). Método: Estudo de coorte, retrospectivo, no qual 156 prontuários de pacientes etilistas e 78 prontuários de pacientes não etilistas com CCEBO diagnosticados no Hospital Haroldo Juaçaba, em Fortaleza, Ceará, foram avaliados, entre 2000 e 2014, para análise de dados como idade, sexo, raça, localização do tumor, estadiamento TNM, tratamentos realizados e sobrevida em 15 anos por meio dos testes X², Long-Rank e modelos de regressão multinomial e de Cox (SPSS 20,0; p<0,05). Resultados: Houve maior prevalência de homens entre os pacientes etilistas (p<0,001), com tumores T3-T4 (p=0,003), linfonodos positivos (p=0,006) que realizaram tratamentos paliativos (p<0,001) e menor prevalência abaixo de 65 anos (p<0,001), quando havia histórico familiar de câncer (p=0,043). A sobrevida dos pacientes etilistas foi menor (p=0,040) e os fatores que diminuíram a sobrevida de maneira independente foram sexo masculino (p=0,042), estadiamento T3-T4 (p=0,004), metástase linfonodal (p=0,012), idade >65 anos (p=0,035) e localização na língua (p=0,042). O sexo masculino foi independentemente associado ao etilismo (p<0,001). Conclusão: O álcool é um fator de prognóstico em pacientes com CCEBO, mostrando maior prevalência em pacientes T3-T4 e, assim, influenciando negativamente no prognóstico.


Introduction: Squamous cell carcinoma is the most important tumor in the head and neck region, due to its incidence and mortality. It is known that factors as alcohol consumption are related to the decrease of the survival of tumors, either stimulating tumor progression or causing considerable comorbidities, being an important study factor. Objective: Evaluate the influence of alcohol history on clinical and prognostic characteristics of patients with mouth oropharynx squamous cell carcinoma (MOSCC). Method: A retrospective cohort study in which 156 charts of alcoholic patients and 78 medical charts of non-alcoholic patients with MOSCC diagnosed at Haroldo Juaçaba Hospital in Fortaleza, state of Ceará were evaluated between 2000 and 2014 for data analysis such as age, gender and race, tumor location, TNM staging, treatments performed and 15-year survival through X², Long-Rank and Cox and multinomial regression models (SPSS 20.0; p <0.05). Results: Men were more prevalent among alcoholic patients (p <0.001), with T3/4 tumors (p = 0.003), positive lymph nodes (p = 0.006) who submitted to palliative treatments (p<0.001) and lower prevalence under 65 years (p <0.001), when there was a family history of cancer (p = 0.043). The survival of alcoholic patients was lower (p = 0.040) and the factors that independently reduced survival were male sex (p = 0.042), T3-T4 staging (p = 0.004), lymph node metastasis (p = 0.012), age> 65 years (p = 0.035) and tumor in the tongue (p = 0.042). Male sex was independently associated with alcohol consumption (p<0.001). Conclusion: Alcohol is a prognostic factor in patients with MOSCC, showing a higher prevalence in T3-T4 patients and, thus, negatively influencing the prognosis.


Introducción: El carcinoma de células escamosas es el tumor de mayor importancia en la región de cabeza y cuello, debido a su incidencia y mortalidad. Se sabe que factores como el consumo de alcohol están relacionado con la disminución de la supervivencia de tumores tanto estimulando la progresión tumoral, como provocando comorbilidades considerables, siendo un factor de estudio importante. Objetivo: Evaluar la influencia del historial del consumo de alcohol en las características clínicas-pronósticas de pacientes con carcinoma de células escamosas oral y orofaringe (CCEOO). Método: Estudio retrospectivo en el que se evaluaron 156 registros médicos de pacientes consumidores de alcohol y 78 de pacientes no alcohólicos con CCEOO diagnosticados en el Hospital Haroldo Juaçaba, en Fortaleza, Ceará, entre 2000 y 2014, para el análisis de datos como edad, sexo raza, escolaridad, los antecedentes familiares, vínculo matrimonial, registro en el servicio, ubicación del tumor, clasificación de TNM, los tratamientos realizados y la supervivencia durante 15 años a través de las pruebas X² Long-Rank y modelos de regresión multinomial y de Cox (SPSS 20.0; p<0,05). Resultados: Hubo una mayor prevalencia de hombres entre pacientes alcohólicos (p<0,001), con tumores T3-T4 (p=0,003), ganglios linfáticos positivos (p=0,006), y realizó tratamientos paliativos (p<0,001) y menor prevalencia en paciente menores de 65 años (p <0,001); cuando se presentaron antecedentes familiares de cáncer (p=0,043). La supervivencia de los pacientes alcohólicos fue menor (p=0,040); y los factores que disminuyeron la supervivencia de forma independiente fueron hombres (p=0,042); estadificación t3-t4 (p=0,004); metástasis a ganglios linfáticos (p=0,012); edad > 65 años (p=0,035); localización de la lengua (p=0,042). El sexo masculino se asoció independientemente con el consumo de alcohol (p<0,001). Conclusión: El alcohol define el pronóstico en pacientes con CCEOO, muestra una mayor prevalencia en pacientes con T3-T4, por lo tanto, influye negativamente en el pronóstico.

ABSTRACT

Tobacco and betel quid are the most common cause of oral cancer in India. Very often oral cancers are preceded by a visible oral precursor lesion called as potentially malignant disorder (PMD). Aim: The aim of this study was to assess the prevalence of oral PMDs associated with habits in urban and rural areas of Puducherry Union territory, India. Methods: A cross-sectional descriptive study in urban and rural areas of Puducherry was conducted. The study group comprised of 450 patients with positive history of oral habits. A standard structured questionnaire was designed to record information about demographic details, socioeconomic status, type, duration and frequency of habits followed by clinical oral examination by single trained and calibrated examiner to detect the presence of PMD. Statistical analysis used: EpiData software (version 3.1). Descriptive statistics were presented for all variables. Pearson's Chi-Square test and adjusted odds ratio (ORs) with 95% confidence interval (CI) were calculated to estimate the suspected risk factors for PMD by using multivariate logistic regression analysis. P-value of ≤ 0.05 was considered to be statistically significant. Results: Prevalence of habit associated oral PMD was 64.2%. Females were more prone to develop PMDs (68.3%) as compared to males (62.8%). PMD was more common in the age group of 51-60 years (69.2%). Smoking with alcohol consumption was the most common oral habit. Habits, socio-economic status and diet were significantly associated with development of oral PMDs in our study population. Multivariate logistic regression analysis showed that chronic betel quid chewing and smoking were significant risk factors for PMD. Increased frequency of vegetable consumption reduced the risk of PMD. Conclusions: Oral PMD were observed in more than half of the subjects with oral habits in Puducherry. Clearly, there is an increased risk of PMD with increased duration of tobacco and betel quid use in this region. Patients and public need to be educated regarding PMD and encouraged to quit habits so as to prevent high risk population from developing cancer

ABSTRACT

OBJECTIVE@#To construct a PA28γ overexpression cell line and determine its effects after infecting an oral squa-mous cell carcinoma (OSCC) cell line.@*METHODS@#The PA28γ gene was cloned into the pLOV.CMV.cherry.2A.EF1a.PuroR lentiviral vector by polymerase chain reaction (PCR), and PCR and DNA sequencing alignment analysis were used for identification. Then, 293T cells were used to package viral diseases. Infected OSCC cells were used to construct a cell line with stable PA28γ overexpression. Finally, the level of PA28γ expression in the OSCC cell line was detected through Western blot.@*RESULTS@#The successful construction of PA28γ recombinant lentiviral vectors was confirmed by DNA sequencing. The results of immunofluorescence showed that the PA28γ overexpression lentivirus successfully infected the OSCC cells and showed cherry red fluorescence. The results of Western blot demonstrated that the constructed cells with stable PA28γ overexpression significantly increased the expression of PA28γ.@*CONCLUSIONS@#The PA28γ overexpression lentiviral vector can significantly increase its protein expression in OSCC cells. We provide a stable OSCC cell line for further study on the effect of PA28γ in OSCC.

ABSTRACT

OBJECTIVE@#To study the effect of the focal adhesion kinase inhibitor TAE226 on epithelial-mesenchymal transition (EMT) in human oral squamous cell carcinoma (OSCC) cell line.@*METHODS@#HSC-3 and HSC-4 cells were cultured with TAE226 under different concentrations (0, 1, 5, and 10 μmol·L⁻¹) for 24, 48, and 72 h. Real-time quantitative polymerase chain reaction was performed to detect the mRNA expressions of E-cadherin and Vimentin. The protein expressions of E-cadherin and Vimentin were determined by Western blot assay after 48 h of TAE226 treatment.@*RESULTS@#Real-time quantitative polymerase chain reaction showed that increasing the TAE226 dose and reaction time resulted in increased and decreased E-cadherin and Vimentin mRNA expressions, respectively (P<0.05). Western blot assays showed that increasing the TAE226 dose resulted in increased and decreased E-cadherin and Vimentin protein expressions, respectively (P<0.05).@*CONCLUSIONS@#TAE226, which is expected to be an effective drug for OSCC treatment, can effectively inhibit the EMT of the OSCC cell line.

ABSTRACT

The relationship between areca nut as a primary carcinogen and oral cancer has been widely concerned. Areca can change the levels of reactive oxygen species (ROS) and autophagy in cells, and the levels of ROS and autophagy are closely related to the occurrence and development of tumors. This paper reviewed the relationships among areca nut, intracellular ROS, and autophagy.

ABSTRACT

Renal transplant patients are treated with immunosuppressive drugs that decrease the effectiveness of the immune system, making them more prone to developing cancer. Skin and lip carcinomas are common malignancies encountered after transplantation, whereas oral carcinomas are rare. We report the case of a 51-year-old female Caucasian patient, with no history of smoking, who presented white lesions on the tongue and an ulcerated lesion on the lower lip beginning 4 months prior. Diagnosis of squamous cell carcinoma for both lesions was made following incisional biopsies. Interestingly, the patient reported a renal transplantation 23 years prior, and was maintained on a combination of cyclosporine, mycophenolate sodium and prednisone. The patient also presented a history of several basal and squamous cell carcinomas on sun-exposed areas of the skin. Both lesions were surgically excised. No sign of recurrence or new lesions in the oral cavity have been observed; however, new skin lesions are frequently diagnosed. This case report highlights that oral cancers may occur in transplant patients in the absence of classical risk factors. Thus, clinicians must be aware of the importance of thorough oral examination in transplant patients in routine follow-up.

ABSTRACT

Sporadic Burkitt lymphoma (SBL) is a variant of Burkitt lymphoma that occurs worldwide, affecting mainly children and young adults. Association with Epstein-Barr virus (EBV) can be identified in approximately 20-30% of cases. Herein we described a case of a 63-year-old male presenting intraoral bilateral mandibular swelling, subjacent to fixed dental prosthesis, with one month of duration. Incisional biopsies were performed, and after two days, the patient was hospitalized due to malaise and breathing difficulty, and died after a week when an abdominal tumor was detected. The mandibular biopsies revealed a diffuse proliferation of medium-sized monomorphic atypical lymphoid cells exhibiting numerous mitoses and areas of "starry-sky" pattern. The tumor showed immunohistochemical positivity for CD20, CD10, Bcl-6, and Ki-67 (≈ 100%); it was negative for CD3, Bcl-2, Vs38c, and MUM-1. Positivity for EBV was found by in situ hybridization. The final diagnosis was intraoral SBL positive for EBV. Clinical, morphological and molecular criteria are necessary for the correct diagnosis of aggressive B-cell neoplasms positive for EBV in elderly patients.

ABSTRACT

Neurofibrosarcoma is a rare malignant neoplasm of the head and neck region and accounts for 8% to 16% of all cases. Its origin is varied and may stem from cells of the peripheral nerves, develop de novo, or result from malignant transformation of preexisting neurofibromas. Because the features of neurofibrosarcomas are heterogeneous, the data retrieved during clinical examinations are of great aid for diagnosis. In this case, owing to clinical features and the fact that the patient had neurofibromatosis type 1, the hypothesis of neurofibrosarcoma was promptly established. The final diagnosis was confirmed by associating clinical, imaging, and pathological data. After the treatment, the patient has been followed up for 10 years, with no evidence of recurrence.

ABSTRACT

RESUMEN Introducción: Las neoplasias de cabeza y cuello representan el 17,6 por ciento a nivel mundial. El cáncer de la cavidad bucal es uno de los más comunes que aparece en dicha región; el 95 por ciento corresponde a carcinoma epidermoide con un pobre pronóstico de supervivencia, debido a que algunos se desarrollan a partir de trastornos potencialmente malignos peligrosamente asintomáticos, por lo que su detección precoz es imprescindible. Objetivo: Caracterizar los trastornos bucales potencialmente malignos mediante aspectos epidemiológicos, clínicos y topográficos en adultos atendidos en el subcentro de salud de Montalvo. Métodos: Se realizó un estudio descriptivo y transversal en 99 pacientes atendidos en el subcentro de salud de Montalvo en Ambato, Ecuador, desde noviembre de 2012 a enero de 2013. Los datos fueron recogidos en la historia clínica estomatológica, que incluyó: datos generales, interrogatorio y examen físico de la cavidad bucal. Los trastornos bucales potencialmente malignos que se consideraron fueron la leucoplasia, eritroleucoplasia, eritroplasia y paladar del fumador invertido. Se aplicó la estadística descriptiva y el estadígrafo chi cuadrado de Sperman. Se trabajó con confidencialidad en el manejo de los datos obtenidos y con la autorización correspondiente al consentimiento. Resultados: Los pacientes con más de 60 años representaron el grupo de edad más afectado para el 60,6 por ciento, con un predominio del sexo femenino (54,5 por ciento). El color de la piel no tuvo una diferencia significativa. El trastorno más frecuente fue la leucoplasia (30 por ciento), seguida de la eritroleucoplasia (15 por ciento) y la eritroplasia (11 por ciento). El 75,8 por ciento de los pacientes no presentó síntomas, sin embargo, el 73 por ciento de los casos con lesiones presentó trauma físico. La localización más frecuente de la leucoplasia fue la mucosa del carrillo y la base de la lengua. Conclusiones: La leucoplasia, la eritroleucoplasia y la eritroplasia fueron los trastornos bucales potencialmente malignos más frecuentes, localizados con mayor frecuencia en la base de la lengua y la mucosa del carrillo, con un predominio en los pacientes mayores de 60 años y en las mujeres(AU)


ABSTRACT Introduction: Head and neck neoplasms represent 17.6 percent worldwide. Cancer of the oral cavity is one of the most common that appear in this region, being 95 percent epidermoid carcinoma with a poor prognosis of survival because they develop from premalignant lesions dangerously asymptomatic, the reason why the precocious detection is imperative. Objective: Characterize potentially malignant oral disorders through epidemiological, clinical and topographical aspects in adults served at the Montalvo health subcenter. Methods: A descriptive and cross-sectional study was conducted on 99 patients treated at the Montalvo health subcentre in Ambato, Ecuador, from November 2012 to January 2013. The data were collected in the stomatological medical history, which included: general data, interrogation and physical examination of the oral cavity. The potentially malignant oral disorders considered were leukoplakia, erythroleukoplakia, erythroplasia and the palate of the inverted smoker. The descriptive statistic and the Sperman chi square statisticwast were applied. It was worked with confidentiality in the handling of the data obtained and with the authorization corresponding to the consent. Results: Patients over 60 years of age accounted for the most affected age group for 60.6 percent, with a female predominance (54.5 percent). The skin color did not make a significant difference. The most common disorder was leukoplakia (30 percent), followed by erythroleukoplakia (15 percent) erythroplasia (11 percent). 75.8 percent of patients had no symptoms, however 73 percent of injured cases had physical trauma. The most common location of leukoplakia was the mucosa of the cheek and the base of the tongue. Conclusion: Leukoplakia, erythroleukoplakia and erythroplasia were the most common potentially malignant oral disorders, most commonly located at the base of the tongue and mucosa of the carrillo, with predominance in patients over 60 years of age and in patients over 60 years of age and in Women(AU)

ABSTRACT

Resumen Introducción: En Colombia, en el periodo 2007-2011, se estima que se diagnosticaron alrededor de 1.500 casos de cáncer de cavidad oral y que por esta causa fallecieron 500 personas, en su mayoría eran hombres. La etiología de esta enfermedad está relacionada con el virus del papiloma humano y, el consumo de alcohol y de cigarrillo. Este estudio buscó cuantificar el efecto en la incidencia del cáncer de cavidad oral del cambio hipotético en la prevalencia de factores de riesgo como consumo de alcohol y, de cigarrillo e infección por virus del papiloma humano en Colombia para el periodo 2015-2050. Métodos: Modelo de simulación macro basado en datos secundarios. Resultados: Según los escenarios simulados, al eliminar el consumo de cigarrillo, alcohol e infección por virus del papiloma humano en la población colombiana probablemente sería posible evitar del 27,6% al 82,1% de los casos nuevos de cáncer de cavidad oral en el país en el periodo 2015-2050. Conclusiones: Bajo los supuestos de un escenario basado en las expectativas de la OMS, las estimaciones del modelo elaborado prevé un posible aumento de los casos de cáncer de cavidad oral asociados al consumo de alcohol y un bajo impacto en la prevención con las medidas actuales, por lo que puede ser necesario que se pongan en marcha acciones para disminuir el consumo de alcohol, así como de cigarrillo. Aunque la dirección de los cambios está bien demostrada en los resultados, es importante tener en cuenta que un modelo de simulación depende de muchos supuestos y por ende tiene limitaciones.


Abstract: Introduction: It is estimated that in the period 2007-2011, around 1500 new cases of oral cavity were diagnosed in Colombia, and that around 500 people died of this cause, the majority men. The etiology of this disease is related to the human papilloma virus, alcohol and cigarette use. This study tries to quantify the effect on oral cancer incidence of a hypothetical change in the prevalence of these risk factors in the period 2015-2050. Methods: macrosimulation models based on secondary data. Results: According to the simulated scenarios, elimination of cigarette and alcohol use and elimination of infection by the human papillomavirus in the Colombian population, would probably prevent 27.6 % to 82.1 % of all new cases of oral cavity cancer expected to occur in the period 2015-2050. Conclusions: according to the projections produced by the World Health Organization and the models we specified, there will be a potential increase in the number of new patients diagnosed with oral cavity cancer associated with the use of alcohol and a low impact of the interventions currently in place. It will be necessary to implement measures to descrease alcohol consumption and sustain current efforts to reduce cigarette use. It is important to take into account the limitations of the simulation models.
