Cáncer de cavidad oral en pacientes del departamento de cirugía de cabeza y cuello - cátedra y servicio de otorrinolaringología del Hospital de Clínicas - Universidad Nacional de Asunción / Oral cavity cancer in patients from the department of head and neck surgery - chair and otorhinolaryngology service of the Hospital de Clínicas - National University of Asunción

La cavidad oral está continuamente expuesta a carcinógenos inhalados e ingeridos (tabaco y alcohol principalmente), y por lo tanto es el sitio más común para el origen de neoplasias en la región de la cabeza y el cuello.Para esta investigación, se realizó un estudio observacional descriptivo, de corte transversal, retrospectivo, de muestreo no probabilístico de casos consecutivos. Se incluyó a pacientes mayores de edad, con diagnóstico clínico y anatomopatológico de cáncer de cavidad oral.Así, se incluyó una serie de 17 casos de carcinoma escamocelular oral, 13 hombres (76 %) y 4 mujeres (24 %), donde la edad de los individuos osciló entre 32 y 73 años.El 65 % de los pacientes era fumador y el 71% refirió consumo de bebidas alcohólicas.La lengua fue la localización tumoral más frecuente, con el 71% de las personas que se encontraba en estadio IV, y con moderado grado de diferenciación histológica. Como conclusión, se determinó que la mayor parte de los pacientes de este estudio correspondían al sexo masculino de 50 a 70 años. Un alto porcentaje de los pacientes refería el hábito tabáquico, y mayor aún el consumo de alcohol. El subsitio más frecuentemente afectado es la lengua, en estadios avanzados y moderado grado de diferenciación.

INTRODUCTION: The oral cavity is continuously exposed to inhaled and ingested carcinogens (mainly tobacco and alcohol), and therefore it is the most common site for the origin of neoplasms in the head and neck region. METHODS: A descriptive, retrospective, observational study of non-probabilistic sampling of consecutive cases was carried out. Adult patients with a clinical and pathological diagnosis of oral cavity cancer were included. RESULTS: A series of 17 cases of oral squamous cell carcinoma was included, 13 men (76%) and 4 women (24%). The age of the individuals ranged between 32 and 73 years.65% of the patients were smokers, and 71% reported consumption of alcoholic beverages.The tongue was the most frequent tumor location, 71% were in stage IV, and with a moderate degree of histological differentiation. CONCLUSION: Most of the patients in this study were males between 50 and 70 years of age. A high percentage of patients reported smoking, and an even higher percentage of alcohol consumption. The most frequently affected subsite is the tongue, in advanced stages and a moderate degree of differentiation.

Autopercepción y condición de salud bucal en el anciano / Self-perception of oral health in the elderly and oral health condition

Introducción: Debido al aumento en la esperanza de vida y, en consecuencia, al aumento en el número de personas mayores, la asociación entre los estados de salud se vuelve relevante en términos de salud pública, ya que además de los años vividos, la calidad de vida de estos pacientes es importante. Objetivo: Evaluar la autopercepción y el estado de salud bucal en personas mayores. Métodos: Estudio observacional, de corte transversal (enero-julio del 2019) en el que se realizaron cuestionarios GOHAI (índice de evaluación de la salud oral geriátrica) y el cuestionario sobre el tipo, el tiempo de uso y la limpieza de las prótesis dentales, el cáncer oral y los datos socioeconómicos. La presencia de posibles lesiones orales también se evaluó mediante examen clínico. Los sujetos incluidos en la muestra eran ancianos (60 años o más) que asistían a las unidades de salud de Aracaju. Resultados: Participaron 55 mujeres y ocho hombres. Al evaluar el índice de evaluación de la salud oral geriátrica, se verificó que el 47,6 por ciento de la muestra tenía una mala percepción de la salud oral. Se encontraron asociaciones entre el índice de evaluación de la salud oral geriátrica entre la última visita al dentista, la adaptación de la prótesis dental y las heridas bucales (p < 0,05). Las lesiones orales más prevalentes fueron mucosa rojiza o irritada (35,7 por ciento) y eritroplasia (14,2 por ciento) y se detectó que el 76 por ciento de las prótesis tenían grietas o suciedad. El 77,7 por ciento de los participantes en el estudio solo utilizaban dentífrico como material de limpieza de la prótesis. Conclusión: La salud bucal autopercibida y las condiciones de salud bucal de los ancianos evaluados se consideraron deficientes, se observa la presencia de prótesis mal adaptadas y agrietadas, además de mucositis(AU)

Introduction: due to the increase in life expectancy and, consequently, to the increase in the number of elderly people, the association between health states becomes relevant in terms of public health, since in addition to the lived years the quality of life of these patients is important. Objective: evaluate the self-perception of oral health and check the oral health condition of the elderly. Methods: observational cross-sectional study (January to July / 2019) in which questionnaires were the GOHAI (Geriatric Oral Health Assessment Index) questionnaire and questionnaire about type, time of use and cleaning of dental prostheses, oral cancer and socioeconomic data. The presence of possible oral lesions was also assessed by clinical examination. The subjects included in the sample were elderly (60 years or older) attending the Aracaju Health Units. Results: fifty-five were female and eight male. When evaluating the Geriatric Oral Health Assessment Index, it is verified that 47.6 percent of the sample has poor self-perception of oral health. Associations were found between GOHAI Index for last visit to the dentist, dental prosthesis adaptation and mouth wound (p < 0.05). The most prevalent oral lesions were reddish or irritated mucosa (35.7 percent), followed by erythroplakia (14.2 percent), 76 percent of the prostheses had cracks or dirt. About the cleaning of the protests, 77.7 percent use only dentifrice as cleaning material. Conclusion: self-perceived oral health and oral health conditions of the elderly evaluated were considered poor, in the presence of poorly adapted and cracked prostheses, in addition to mucositis(AU)

Incidencia de patologías bucomaxilares en un período de aislamiento social preventivo y obligatorio de la pandemia COVID-19 / Incidence of buccomaxillofacial pathologies in a period of preventive and mandatory social isolation due to the COVID-19 pandemic

La urgencia en la práctica odontológica incluye no solo la atención de pacientes con dolor e infección, sino también la atención de pacientes que presentan patologías con presunción diagnóstica de agresividad y/o malignidad. El objetivo de este estudio fue analizar la incidencia de las patologías bucomaxilares biopsiadas en el Servicio de Urgencias y Orientación de Pacientes (SUyOP), y diagnosticadas en el Laboratorio de Patología Quirúrgica de la Cátedra de Anatomía Patológica (LPQ-CAP) de la Facultad de Odontología de la Universidad de Buenos Aires (FOUBA), en un período del Aislamiento Social Preventivo y Obligatorio de la pandemia COVID-19. Se realizó un estudio observacional, descriptivo y retrospectivo de pacientes que se presentaron para la atención odontológica en el período de tiempo comprendido entre el 20 de marzo al 21 de junio de 2020. Se registraron los pacientes que presentaron lesiones bucales con indicación de biopsia. Del total de pacientes evaluados (4854), 48 presentaron patologías con presunción diagnóstica de agresividad y/o malignidad. Las patologías más frecuentes fueron las neoplasias malignas (21 casos), siendo la entidad prevalente el carcinoma de células escamosas. Para el LPQ-CAP, las muestras biópsicas remitidas por el SUyOP representaron el 44% del total de las muestras recibidas. Si bien la incidencia de patologías bucomaxilares biopsiadas y diagnosticadas fue baja (1%) es de destacar que el diagnóstico histopatológico correspondió, en la mayoría de los casos, a patologías neoplásicas. De allí la importancia de la atención de urgencia a pacientes que presentan lesiones con presunción diagnóstica de malignidad/agresividad (AU)

Diagnosis of mucosal changes and hospitalized oral cancer patients in Brazil: influence of socioeconomic factors

Abstract This study aimed to analyze the influence of socioeconomic factors on the frequency of diagnoses of oral mucosal changes and the number of hospitalized patients with oral and oropharyngeal cancer in Brazil. This cross-sectional study analyzed data from all Brazilian cities in the period 2011-2017. The frequency of diagnoses of oral mucosal changes and the number of hospitalized patients of oral and oropharyngeal cancer in Brazil were extracted from the Primary Care Information System (SIAB) and Brazilian National Cancer Institute (INCA) databases. The socioeconomic factors evaluated were the Gini coefficient of inequality, municipal Human Development Index (MHDI), inadequate basic sanitation rate, employment rate, illiteracy rate and expected years of schooling. Associated factors were examined using bivariate Spearman's correlations and multivariate Poisson regressions, and statistically significant (p < 0.05) correlations between study variables and regression coefficients were obtained. A higher frequency of diagnoses of mucosal changes was observed in cities with a higher Gini coefficient (B = 11.614; p < 0.001), higher MHDI (B = 11.298; p < 0.001), and higher number of hospitalized patients with oral and oropharyngeal cancer (B = 0.001, p < 0.002). Cities with higher Gini coefficients (B = 8.159, p < 0.001), higher inadequate basic sanitation rates (B = 0.09, p = 0.001), lower expected years of schooling (B = -0.718, p < 0.001), and higher illiteracy rates (B = 0.191, p < 0.001) had a higher frequency of hospitalized patients with oral and oropharyngeal cancer. In conclusion, more developed cities showed a higher frequency of diagnoses of mucosal changes. Greater inequality and worse socioeconomic conditions are associated with a higher frequency of hospitalized patients with oral and oropharyngeal cancer in Brazil.

Screening de lesiones orales malignas y potencialmente malignas en funcionarios de Universidad de Valparaíso y Universidad Viña del Mar durante los años 2016 - 2017 / Screening of malignant and potentially malignant oral lesions in employee of the University of Valparaíso and the University of Viña del Mar during 2016 - 2017

El objetivo de este estudio es determinar la prevalencia de lesiones orales malignas y potencialmente malignas (LPM) en funcionarios de la Universidad de Valparaíso y de Viña del Mar durante los años 2016 - 2017. Fueron citados 161 funcionarios, quienes accedieron a una encuesta que evaluaba factores de riesgo de cáncer oral (tabaco y alcohol) y si habían escuchado de la patología, sumado a un examen clínico. De los pacientes examinados, se diagnosticaron 121 lesiones de las cuales 2 fueron diagnosticadas como lesiones potencialmente malignas: Liquen plano y Leucoplasia, con una prevalencia de 1,7 %. El 50,3 % de los pacientes sabía de la existencia de cáncer oral. El Screening es una medida que permite dar a conocer a la población la existencia de cáncer oral y alertarlos sobre la importancia de su examen para su identificación de manera temprana.

The objective of this study is to determine the prevalence of malignant and potentially malignant oral lesions (PML) in University of Valparaíso and Viña del Mar employees, during the years 2016 - 2017. We cited 161 employees, who accessed a survey evaluating risk factors for oral cancer (tobacco and alcohol) and if they had heard of the disease. In addition, a clinical examination was carried out. Of the patients examined, 121 lesions were diagnosed, of which 2 were diagnosed as potentially malignant lesions: Lichen planus and Leukoplakia, with a prevalence of 1.6 %. 50.3 % of patients knew of the existence of oral cancer. Epidemiological designs are needed to better establish causality between risk factors and malignant or, potentially malignant lesions.

Análisis de los Resultados nacionales obtenidos por grupos estatales de investigación del el cáncer ruso. Programa de Cribado de Enfermedades de la Mucosa Oral y Borde Bermellón / Analysis of The Results Obtained by National Research Groups with The Russian State Cancer Program for The Screening of Diseases of The Oral Mucosa and The Vermillion Border

This article analyzes the results obtained by national research groups in the implementation of the Russian State Cancer Program. From 2015 to the first half of 2019, specialists studied the epidemiology and structure of oncological and precancerous diseases of the oral mucosa and the vermillion border in 486,059 persons aged 18-92 years living in Tula, the Tula region, Moscow and Noyabrsk as a result of screening and medical aid appealability. In this period, the productivity of the research group from Tula grew by the factor of 18.92. The results of the research confirm low cancer alertness of practicing dentists. An individual patient registration card has been developed to systematize data and create a diagnostic register for the screening of cancer and precancerous diseases of the oral mucosa and the vermillion border.

Oral Cancer: Socio-Spatial Analysis of a Brazilian Sample / Câncer Bucal: Análise Socioespacial de uma Amostra Brasileira / Cáncer Oral: Análisis Socioespacial de una Muestra Brasileña

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.

Histórico de Consumo de Álcool como Fator Preditivo de Sobrevida em Pacientes com Carcinoma de Células Escamosas de Boca e Orofaringe: Follow-up de 15 Anos / Alcohol Consumption History as a Predictive Factor of Survival in Patients with Mouth and Oropharyngeal Squamous Cell Carcinoma: Follow-up of 15 Years / Historia del Consumo de Alcohol como Factor Predictivo para la Supervivencia en Pacientes con Carcinoma de Células Escamosas Bucales y Orofaríngeas: Seguimiento de 15 Años

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.

Oral squamous cell carcinoma: a clinicopathological study on 194 cases in northeastern Brazil. A cross-sectional retrospective study

ABSTRACT BACKGROUND: Only a few studies have evaluated the clinicopathological features of oral squamous cell carcinoma (SCC) in Brazil, and most were conducted in the most industrialized region of the country, i.e. the southeastern region. The aim of this study was to evaluate the clinicopathological features of this malignant neoplasm in northeastern Brazil. DESIGN AND SETTING: Retrospective study performed in an oral pathology laboratory in Recife, Brazil. METHODS: All cases of oral SCC that occurred between 2000 and 2015 were studied. Clinical data were recorded and histological slides were reviewed. Statistical analysis was performed using the chi-square test (P ≤ 0.05). RESULTS: A total of 194 cases were evaluated. The male-to-female ratio was 1.5:1. The mean age was 65.4 years, and only 6.6% of the cases occurred in patients younger than 41 years. Most tumors consisted of well-differentiated SCC (54.6%). CONCLUSIONS: The findings of this study highlight the higher prevalence of oral SCC among women and the increasing number of cases among young patients. Thus there is no specific risk group for oral SCC, as in the past. This fact needs to be taken into consideration in clinical routine care, so that apparently innocuous malignant lesions do not go unnoticed in these individuals.

Oral health of older people: tracking soft tissue injuries for the prevention of oral cancer / Saúde bucal de idosos: rastreio de lesões dos tecidos moles na prevenção do câncer bucal / Salud bucal de personas mayores: rastreo de lesiones de tejidos blandos en la prevención del cáncer bucal

ABSTRACT Objective: To detect oral soft tissue injuries in older people. Method: A quantitative analytical cross-sectional study conducted in Fortaleza, Ceará. Individual interviews addressed age, gender, marital status, income, and education. The community oral health indicator was used to detect oral soft tissue injuries and their location. Results: Most of the 821 participants aged 60-100 years were women (580; 70.6%), attended school for up to 5 years (401; 48.8%), were illiterate (201; 24.5%), were retired (608; 74.1%), and received up to 2 wages (701; 85.4%). A total of 604 participants (73.6%) wore dentures. Injuries included red patches (152; 55.9%), blisters (58; 21.3%), lesions and/or wounds (39; 14.3%), and white patches (30; 11%). Locations of injuries were the roof of the mouth (167; 61.4%), gums (62; 22.8%), cheeks (39; 14.3%), tongue (15; 5.5%), lips (15; 5.5%), and the floor of the mouth (12; 4.4%). Injuries were associated with age (p<0.001), retirement (p=0.005), education (p=0.010), dentures (p<0.001) and red patches (p<0.001). Conclusion: Tracking soft tissue injuries and referring older adults with suspected malignant lesions to the health team should be included as oral cancer identification and prevention measures. Furthermore, health care providers should raise older adults' awareness of the importance of regular preventive examinations.

Además, los profesionales sanitarios deben concienciar a los ancianos acerca de la importancia de hacer exámenes preventivos regulares.

Demographic and Clinical Profile of Oral Squamous Cell Carcinoma from a Service-Based Population

Abstract The aim of this study was to evaluate the demographic and clinical profile of the oral squamous cells carcinoma (OSCC) cases registered in a center of oral diagnosis in southern Brazil. Eight hundred and six individuals with OSCC from 1959 to 2012 were included in this study. The variables recorded were: sex, age, occupation according to workplace, alcohol and tobacco consumption, skin color, tumor location, histological type, clinical appearance, size, evolution time, presence of pain and lymph node metastasis. Descriptive analysis was performed and the associations between variables were assessed using the chi-square and Fisher's exact test, with a confidence level of 5%. OSSC was more common in males (76.6%) aged between 51 to 70 years (53.9%). The most frequent sites were lower lip vermilion (23.3%), tongue (20.2%) and gingiva/alveolar ridge (18.1%). There was a strong association between outdoor occupation and white skin color with lip squamous cell carcinoma (LSCC). OSCC intraoral lesions were commonly more painful, larger than 2 cm and presented lymphatic metastasis. In conclusion, most of the results confirm the data from literature about sex, age, tumor location and occupation. Moreover, the positive correlations between LSCC and occupation, between LSCC and white skin color, and between bigger lesions and presence of pain/cervical metastasis also corroborate the literature data.

Resumo O objetivo desse estudo foi avaliar o perfil clínico-demográfico dos casos de carcinoma de células escamosas oral (CCEO) oral registrados em um centro de diagnóstico bucal no Sul do Brasil. Oitocentos e seis indivíduos com CCEO de 1959 a 2012 foram incluídos no estudo. As variáveis coletadas foram: sexo, idade, ocupação de acordo com o ambiente de trabalho, consumo de álcool e tabaco, cor de pele, localização do tumor, tipo histológico, aparência clínica, tamanho, tempo de evolução, presença de dor e metástase linfonodal. Foi realizada análise descritiva e as associações entre as variáveis foram avaliadas usando qui-quadrado e teste exato de Fisher, com nível de confiança de 5%. CCE oral foi mais comum em homens (76,6%), entre 51 e 70 anos de idade (53,9%). Os sítios mais frequentes foram vermelhão de lábio inferior (23,3%), língua (20,2%) e gengiva/rebordo alveolar (18,1%). Houve uma forte associação entre ocupação em ambiente externo e cor de pele branca com CCEO em lábio. Lesões intraorais de CCEO foram comumente mais dolorosas, maiores que 2 cm e apresentaram metástase linfática. Em conclusão, a maioria dos resultados confirma os dados da literatura em relação a sexo, idade, localização do tumor e ocupação. Além disso, as correlações positivas entre CCE em lábio e ocupação, entre CCEO em lábio e cor de pele branca, e entre lesões maiores e presença de dor/metástase cervical também corroboram os dados da literatura.

Potentially malignant oral lesions: clinicopathological correlations / Lesões orais potencialmente malignas: correlações clínico-patológicas

ABSTRACT Objective To determine the incidence of potentially malignant oral lesions, and evaluate and correlate their clinical and pathological aspects. Methods The sample consisted of cases clinically diagnosed as oral leukoplakia, oral erythroplakia, erythroleukoplakia, actinic cheilitis, and oral lichen planus treated at a diagnostic center, between May 2012 and July 2013. Statistical tests were conducted adopting a significance level of 5% (p≤0.05). Results Out of 340 patients, 106 (31.2%) had potentially malignant oral lesions; and 61 of these (17.9%) were submitted to biopsy. Actinic cheilitis was the most frequent lesion (37.5%) and the lower lip was the most affected site (49.6%). Among 106 patients in the sample, 48 (45.3%) reported nicotine consumption, 35 (33%) reported alcohol intake and 34 (32.1%) sun exposure while working. When clinical and histopathological diagnoses were compared, oral erythroplakia and atypical ulcer were the lesions that exhibited greater compatibility (100% each). Conclusion In most cases, clinical and histopathological diagnoses were compatible. An association between the occurrence of erythroplakia, leukoplakia and erythroleukoplakia with smoking was observed. Similarly, an association between actinic cheilitis and sun exposure was noted. Erythroleukoplakia presented the highest malignancy grade in this study. Finally, dental surgeons should draw special attention to diagnosis of potentially malignant oral lesions, choose the best management, and control the lesions to avoid their malignant transformation.

RESUMO Objetivo Verificar a incidência das lesões orais potencialmente malignas, e avaliar e correlacionar seus aspectos clínico-patológicos. Métodos A amostra foi composta pelos casos diagnosticados clinicamente como leucoplasia oral, eritroplasia oral, eritroleucoplasia, queilite actínica e líquen plano oral em um serviço de diagnóstico no período entre maio de 2012 e julho de 2013. Foram realizados testes estatísticos adotando-se nível de significância de 5% (p≤0,05). Resultados Dos 340 pacientes examinados, 106 (31,2%) se apresentaram com lesões orais potencialmente malignas; destes, 61 (17,9%) biópsias foram realizadas. A lesão mais frequente foi a queilite actínica (37,5%), e o sítio anatômico mais acometido foi o lábio inferior (49,6%). Entre os 106 pacientes da amostra, 48 (45,3%) relataram consumo de nicotina, 35 (33%) ingeriam bebidas alcoólicas e 34 (32,1%) trabalhavam expostos ao sol. Comparando o diagnóstico clínico com o histopatológico, as lesões que apresentaram maior compatibilidade foram a eritroplasia oral e a lesão ulcerada atípica (100% ambas). Conclusão Na maioria dos casos, houve compatibilidade do diagnóstico clínico com o histopatológico. Notou-se correlação entre a ocorrência de eritroplasia, leucoplasia e eritroleucoplasia com o hábito de fumar, e entre a queilite actínica com a exposição solar. A eritroleucoplasia foi a lesão que demonstrou maior grau de malignização neste estudo. Diante do exposto, recomenda-se maior atenção por parte dos cirurgiões-dentistas ao diagnóstico das lesões orais potencialmente malignas, para aplicação da melhor conduta e controle da lesão, impedindo sua transformação maligna.

Frecuencia de displasia epitelial y carcinoma escamoso en mucosa oral y orofaríngea en Chile, entre los años 1990 y 2009 / Frequency of oral squamous cell carcinoma and oral epithelial dysplasia in oral and oropharyngeal mucosa in Chile

Background: Oral cancer in Chile corresponds approximately to 1.6% of all cancer cases. There are few studies about oral epithelial dysplasia and oral squamous cell carcinoma in the Chilean population. Aim: To determine the frequency of hyperkeratosis, mild, moderate and severe oral epithelial dysplasia, in situ carcinoma and squamous cell carcinoma of the oral and oropharyngeal mucosa in a registry of the Oral Pathology Reference Institute of the Faculty of Dentistry, Universidad de Chile, in a ten years period. Material and Methods: Review of clinical records and pathological plates of 389 patients, obtained between 1990 and 2009. Cases were selected according to their pathological diagnosis, including hyperkeratosis, oral epithelial dysplasia, in situ carcinoma, squamous cell carcinoma and verrucous carcinoma. Results: Forty four percent of cases were squamous cell carcinoma, followed by hyperkeratosis in 37% and mild epithelial dysplasia in 11%. Squamous cell carcinoma was more common in men aged over 50 years. Most of the potentially malignant disorders presented clinically as leukoplakia and squamous cell carcinoma were clinically recognized as cancer. Conclusions: In this study, men aged over 50 years are the highest risk group for oral cancer. Early diagnosis is deficient since most of these lesions were diagnosed when squamous cell carcinoma became invasive. Leukoplakia diagnosis is mostly associated with hyperkeratosis and epithelial dysplasia, therefore biopsy of these lesions is mandatory to improve early diagnosis.

A 10-year analysis of the oral squamous cell carcinoma profile in patients from public health centers in Uruguay

The aim of this study was to evaluate the demographic, clinical, and therapeutic characteristics and predictive factors of poor prognosis in patients with primary oral squamous cell carcinoma (OSCC) in Uruguay. Medical records of patients with the diagnosis of primary OSCC treated between 2000 and 2010 in Uruguayan public hospitals were selected. Data on demographic characteristics, risk factors, clinical features, treatment, and outcome were collected. Associations of independent variables with outcomes were assessed using Pearson chi-squared and Fisher's tests. Of 200 patients with OSCC, 79.4% were men (3.8:1 male:female ratio), with a mean age of 60.75 ± 11.26 years. Tobacco and alcohol consumption were reported by 85.3% and 63.5% of patients, respectively. The most commonly affected location was the tongue (42.5%), with lesions exhibiting ulcerous aspects in 87.9% of cases and pain at the time of diagnosis in 70.4% of cases. One hundred sixty-one (82.1%) patients had advanced-stage (III/IV) OSCC. Surgery was the most common treatment option, and the overall 5-year survival rate was 58.5%. Univariate analysis showed that the predictors of poor prognosis were clinical aspect, size, regional metastasis, clinical stage, and treatment. In Uruguay, OSCC is diagnosed late, which is associated with a low survival rate. Educational and preventive measures and investment to improve early diagnosis should be undertaken.
