ABSTRACT Objective: To assess the level of oral cancer awareness and risk factors perception and the relationship between this awareness and the sociodemographic and behavioral characteristics. Material and Methods: This descriptive study was conducted among rural and urban residents in Lagos State, Nigeria. A multi-stage random sampling method was utilized. The sociodemographic and behavioral characteristics of respondents, as well as their knowledge about oral cancer risk factors, were assessed with a validated questionnaire. The bivariate association was done using an independent t-test and one-way ANOVA. Multivariate regression was used to determine the association between predictor variables and oral cancer knowledge scores. The statistical significance level is set at p<0.05. Results: 590 participants between 18 and 82 years (mean age 34.5 ±13.7) completed the survey. The prevalence of cigarette smoking was 25.7%, of which 16 (1.5%) were heavy smokers (20+ cigarettes per day). The prevalence of alcohol consumption was 66.1%, with 57 (9.7%) being heavy drinkers, consuming drinks for 5-7 days of the week. A high proportion of the respondents (>60%) exhibited gaps in their knowledge of oral cancer. Uneducated participants had lower oral cancer knowledge than those with >12 years of formal education (aOR = 5.347; 95% CI: 4.987-6.240). Participants who were smokers had lower oral cancer knowledge compared with non-smokers (aOR = 3.341; 95% CI: 2.147-4.783); Participants who consumed alcohol had more deficient oral cancer knowledge compared with non-drinkers (aOR = 1.699; 95% CI: 1.087-2.655); While heavy smokers aOR = 4.023; 95% CI: 3.615-4.825) and heavy drinkers aOR = 4.331; 95% CI: 3.158-5.939) had lower oral cancer knowledge compared with those who did not abuse both substances. Conclusion: A high proportion of the respondents exhibited gaps in their knowledge of oral cancer in their responses. Delayed diagnosis of oral cancer can be reduced by increasing the awareness and knowledge of the populace about risk factors and also in the recognition of its signs and symptoms.

Metastatic lesions in the mouth can resemble common inflammatory lesions. Therefore, we set out to investigate oral metastases whose clinical and imaging characteristics mimicked those of harmless lesions, confusing and delaying the diagnosis. For this, a systematic review was carried out from case reports, case series, and cross-sectional studies in the PubMed/Medline, Scopus, Embase-via Elsevier, Virtual Health Library, Web of Science, and gray literature, using PICO strategy without period restriction. We assessed the quality of studies using the Joanna Briggs Institute assessment tool. A narrative synthesis of the data was carried out. Association analyses using chi-square and Fisher's exact tests were performed, with statistical significance at p<0.05. Most of the lesions came from the lung, breast, kidneys, liver, and thyroid. They affected mainly the mandibles of men, between the fifth and seventh decades of life, causing osteolysis. In soft tissue, there were firm swellings, associated with bleeding. Limitations regarding the heterogeneity of the included studies and the absence of clinic pathological descriptions of the tumors substantially reduced the chance of statistical analysis of the data. Knowing the different possibilities of clinical presentation of oral and maxillofacial metastases is important for the diagnost ic suspicion to occur and diagnostic errors to be avoided. Thus, treatment is instituted and survival can be extended. Protocol registration: PROSPERO CRD42020200696.

Las lesiones metastásicas en la cavidad oral pueden parecer similares a lesiones inflamatorias comunes. Por ello, nos propusimos investigar metástasis orales cuyas características clínicas e imagenológicas simularan las de lesiones inofensivas, confundiendo y retrasando el diagnóstico. Para ello, se realizó una revisión sistemática a partir de reportes de casos, series de casos y estudios transversales en PubMed/Medline, Scopus, Embase-vía Elsevier, Virtual Health Library, Web of Science y literatura gris, utilizando la estrategia PICO sin restricción de periodo. La calidad de los estudios se evaluó mediante la herramienta de evaluación del Instituto Joanna Briggs. Se realizó una síntesis narrativa de los datos. Se realizaron análisis de asociación mediante chi-cuadrado y prueba exacta de Fisher, con significancia estadística en p<0,05. La mayoría de las lesiones procedían de pulmón, mama, riñones, hígado y tiroides. Afectan principalmente a las mandíbulas de los hombres, entre la quinta y la séptima década de la vida, provocando osteólisis. En los tejidos blandos, había hinchazones firmes, asociadas con sangrado. Las limitaciones con respecto a la heterogeneidad de los estudios incluidos y la ausencia de descripciones clinicopatológicas de los tumores redujeron sustancialmente la posibilidad de realizar un análisis estadístico de los datos. Conocer las diferentes posibilidades de presentación clínica de las metástasis orales y maxilofaciales es importante para que se produzca la sospecha diagnóstica y se eviten errores diagnósticos. Por lo tanto, se instituye el tratamiento y se puede prolongar la supervivencia. Registro de protocolo: PROSPERO CRD42020200696.

Objetivos: Instruir e orientar ao cirurgião dentista e demais profissionais de saúde a importância da detecção e rastreio precoce de lesões pré-malignas. Revisão de Literatura: O Líquen Plano Oral é uma condição dermatológica crônica, de origem auto-imune, relativamente comum na população, que atinge o epitélio de mucosa e pele, sendo considerada, pela Organização Mundial de Saúde (OMS), uma desordem potencialmente maligna quando associado a áreas de ulceração. A revisão de literatura foi realizada nas bases de dados PubMed e Lilacs. Buscamos investigar o potencial de malignização do Líquen Plano Oral associado a condições erosivas, analisando o processo de carcinogênese no processo inflamatório. Conclusão: Conclui-se que o objeto de estudo ainda é um assunto pouco explorado pela literatura, porém há indícios etiopatológicos que enfatizam o processo de malignização oriundo de uma lesão pré-maligna como o Líquen Plano Oral. Além disso, enfatizamos a importância do diagnóstico precoce das lesões estomatognáticas, para que assim possamos aumentar as chances de cura do paciente.(AU)

Objectives: To instruct and guide dentists and other health professionals on the importance of early detection and screening of pre-malignant lesions. Literature Review: Oral Lichen Planus is a chronic dermatological condition, of autoimmune origin, relatively common in the population, which affects the epithelium of the mucosa and skin, being considered, by the World Health Organization (WHO), a potentially fatal disorder. malignant when associated with areas of ulceration. A literature review was performed on the PubMed and Lilacs databases. We sought to investigate the potential for malignancy of Oral Lichen Planus associated with erosive conditions, analyzing the process of carcinogenesis in the inflammatory process. Conclusion: It is concluded that the object of study is still a subject little explored in the literature, but there are etiopathological accusations that emphasize the process of malignancy arising from a pre-malignant lesion such as Oral Lichen Planus. In addition, we emphasize the importance of early diagnosis of stomatognathic lesions, so that we can increase the patient's chances of cure.(AU)

Solitary fibrous tumor (SFT) is a neoplasm of fibroblastic/myofibroblastic origin with intermediate biological behavior. We report here two cases of SFT affecting an unusual anatomical site in 58-year-old and 40-year-old female patients and discuss the differential diagnosis of this lesion. In case 01, the lesion showed the clinical appearance of an asymptomatic "blister" with normal color, rubbery consistency, measuring 0.3 cm, and affected the lower lip; while in case 02, a symptomatic red nodular lesion with a soft consistency and measuring 0.5 cm affected the floor of the mouth. Excisional biopsies were performed. Microscopically, two well-delimited benign neoplasms were observed, exhibiting the proliferation of ovoid to spindle-shaped mesenchymal cells, vascular spaces with staghorn arrangement, and the absence of mitosis figures. Immunohistochemistry was performed in case 01 to assist in the diagnosis. Weak and diffuse immunostaining was observed for α-SMA and intense and diffuse immunopositivity for Bcl-2 and CD34. Based on histopathological and immunohistochemical features, a diagnosis of SFT was rendered in both cases. The low occurrence and nonspecific clinical features of oral SFT may make its clinical diagnosis difficult. Also, morphological and immunohistochemical are essential for differential diagnosis with other mesenchymal neoplasms.(AU)

O tumor fibroso solitário (TFS) é uma neoplasia de origem fibroblástica/miofibroblastica com comportamento biológico intermediário. Nesse artigo relatamos dois casos de TFS afetando sítios anatômicos incomuns em pacientes do sexo feminino de 58 anos e 40 anos e discutir os seus diagnósticos. No caso 01 clinicamente a lesão apresentou um aspecto de "bolha" assintomática, coloração normal da mucosa, consistência borrachoide medindo 0,3 cm, em região de lábio inferior, enquanto que no caso 02, como uma lesão sintomática, vermelha, nodular com consistência mole e medindo 0,5 cm afetando o assoalho bucal. As biópsias excecionais foram realizadas. Microscopicamente, observamos duas lesões neoplásicas bem delimitadas exibindo uma proliferação de células mesenquimais variando de ovoides a fusiformes, vasos sanguíneos em formato de "chifre de veado", com ausência de figuras de mitoses. No caso 01 foi realizado análise imuno-histoquímica para auxiliar no diagnóstico. Foi observado uma marcação fraca e difusa de α-SMA e uma intensa e difusa imunopositividade para o Bcl-2 e CD34.Baseado nos achados histopatológicos e imuno-histoquímicos o diagnóstico de TFS foi estabelecido em ambos os casos. A baixa ocorrência e os achados clínicos inespecíficos do TFS oral podem dificultar o diagnóstico clínico. Além disso, as análises morfológicas e imuno-histoquimicas são essenciais para realização do diagnóstico diferencial com outras neoplasias mesenquimais.(AU)_

El carcinoma escamoso de cavidad oral corresponde a una de las neoplasias malignas más frecuentes en cabeza y cuello, teniendo una incidencia mundial según GLOBOCAN para el año 2020 de 377.713 casos nuevos. Este cáncer tiene la ventaja potencial de su diagnóstico precoz por su accesibilidad al examen físico, por lo que es importante tener un alto índice de sospecha en pacientes con los factores de riesgo como tabaquismo crónico, consumo de alcohol, consumo de nuez de betel, inmunodeficiencias, entre otros, teniendo una conducta activa con el fin de lograr un diagnóstico precoz. Por otro lado, la etapificación actual incorpora nuevos factores pronósticos, como la profundidad de invasión, con el fin de asignar de mejor forma una clasificación adecuada y con ello, guiar el tratamiento de estos pacientes. Finalmente, se debe procurar un diagnóstico y tratamiento precoz con el fin de lograr los mejores resultados oncológicos.

Squamous cell carcinoma of the oral cavity represents one of the most frequent malignant neoplasms in the head and neck, having an incidence according to GLOBOCAN for the year 2020 of 377,713 new cases. This cancer has the potential advantage of early diagnosis due to its accessibility to physical examination, so it is important to have a high index of suspicion in patients with risk factors such as chronic smoking, alcohol consumption, betel nut consumption, immunodeficiencies, among others, having an active behavior in order to achieve an early diagnosis. On the other hand, the current staging incorporates new prognostic factors, such as depth of invasion, in order to better assign an adequate classification and thus guide the treatment of these patients. Finally, early diagnosis and treatment should be sought in order to achieve the best oncological outcomes.

Cuidados paliativos são um conjunto de procedimentos ofertados ao paciente por uma equipe multidisciplinar com objetivo de garantir bem-estar, autonomia,conforto e alívio de sintomas decorrentes de doença ou tratamento quando a cura é impossibilitada. O câncer representa uma das doenças que possuem chances de evoluir o paciente ao estágio terminal, momento em que cuidados paliativos são indicados e necessários. Dentro da equipe responsável, o cirurgião-dentista atua na prevenção, diagnóstico e tratamento de lesões expressas no sistema estomatognático que se manifestam estimuladas pelo câncer ou pelos tratamentos utilizados. O objetivo desta pesquisa é destacar a função do odontólogo dentro da equipe multidisciplinar paliativista para pacientes oncológicos. Trata-se de uma revisão bibliográfica sistemáticada literatura. Foram feitas buscas nas plataformas Biblioteca Virtual em Saúde (BVS) e Scientific Electronic Library Online (SciELO) e após aplicação dos critérios de inclusão e exclusão foram selecionados 14 artigos. A literatura evidencia que alterações orais estão relacionadas com o curso da neoplasia ou seu tratamento; as lesões mais descritas foram: mucosite, xerostomia, candidíase, cárie, periodontite e osteorradionecrose. Isso faz com que o paciente sofra limitações em realizar atividades básicas, alterando negativamente a sua qualidade de vida. A complexidade da manifestação oral pode interromper o tratamento antineoplásico. As medidas de enfrentamento mais empregadas para a saúde bucal do paciente oncológico são a laserterapia, bochechos com clorexidina 0,12%, instrução de higiene oral, uso de anti-inflamatórios, analgésicos e antifúngicos. A atuação do odontólogo na equipe multidisciplinar oncológica paliativista é indispensável para o controle das manifestações orais.

Palliative care comprises a set of procedures offered by a multidisciplinary team to patients who cannot be cured, aiming to restore and ensure well-being, autonomy, independence, comfort and relief from symptoms resulting from illness or treatments. Cancer commonly leads the patient to the terminal stage, and at this stage palliative care is indicated and necessary. Composing the multidisciplinary team, the dentist works in the prevention, diagnosis and treatment of injuries that arise in the stomatognathic system, which manifest themselves due to cancer or its treatments. The objective of this research was to highlight the work of the dentist in the multidisciplinary team of palliative care for cancer patients. This is a systematic bibliographic review of the literature, with an integrative character. Study searches were performed in the Virtual Health Library (VHL) and Scientific Electronic Library Online (SciELO). After applying the inclusion and exclusion criteria, 14 articles were selected. Results showed that oral alterations are completely related to the development of the neoplasm or its treatment; the most described lesions were: mucositis, xerostomia, candidiasis, osteoradionecrosis, radiation caries and periodontitis. These injuries make the patient suffer limitations to perform basic activities, such as eating or communicating, negatively altering their quality of life. The complexity of the oral manifestation can determine the interruption of the anticancer treatment. The most used coping measures for the oral healthof cancer patients are: low- potency laser therapy, mouthwash with 0.12% chlorhexidine, instructionin oral hygiene and use of anti-inflammatory, analgesic and antifungal drugs. The role of dentists in the multidisciplinary palliative oncology team is essential for the control of oral lesions.

Los cuidados paliativos son un conjunto de procedimientos ofrecidos al paciente por un equipo multidisciplinar con el objetivo de garantizar el bienestar, la autonomía, el confort y el alivio de los síntomas derivados de la enfermedad o del tratamiento cuando la curación es imposible. El cáncer representa una de las enfermedades que tienen posibilidades de evolucionar al paciente hasta la fase terminal, momento en el que los cuidados paliativos son indicados y necesarios. Dentro del equipo responsable, el cirujano dentista actúa en la prevención, diagnóstico y tratamiento de las lesiones expresadas en el sistema estomatognático que se manifiestan estimuladas por el cáncer o por los tratamientos utilizados. El objetivo de esta investigación es destacar la función del odontólogo dentro del equipo paliativo multidisciplinar para pacientes oncológicos. Se trata de una revisión bibliográfica sistemática. Se realizaron búsquedas en las plataformas Virtual Health Library (BVS) y Scientific Electronic Library Online (SciELO) y tras aplicar los criterios de inclusión y exclusión, se seleccionaron 14 artículos. La literatura muestra que las alteraciones orales están relacionadas con el curso del cáncer o su tratamiento; las lesiones más comúnmente descritas fueron: mucositis, xerostomía, candidiasis, caries, periodontitis y osteorradionecrosis. Esto hace que el paciente sufra limitaciones para realizar actividades básicas, alterando negativamente su calidad de vida. La complejidad de la manifestación oral puede interrumpir el tratamiento antineoplásico. Las medidas de afrontamiento más utilizadas para la salud bucodental de los pacientes con cáncer son la terapia láser, los enjuagues bucales con clorhexidina al 0,12%, las instrucciones de higiene bucodental y el uso de fármacos antiinflamatorios, analgésicos y antifúngicos. La actuación del odontólogo en el equipo multidisciplinar de oncología paliativa es fundamental para el control de las manifestaciones orales.

Objective: To contribute to early diagnosis of lesions in older patients, including potentially malignant lesions or those suspected of oral cancer by support of a web-based teledentistry platform. Material and Methods:This report contains information from 27 patients with oral lesions out of a total of 135 who received mobile dental care. Specialists who participated in the study involved professionals from the disciplines of periodontics, temporomandibular disorders, oral implantology, oral radiology, oral pathology and geriatrics. Referral consultations were carried out synchronously or asynchronously. Clinical information sent to oral pathology specialists involved a medical history and a traditional description of the lesion which considered size, color, limits, symptomatology, type of surface, consistency, location, and evolution. This information was complemented with a three-dimensional representation of the lesion, simulating an extra/intra oral clinical examination including a marker tool that allows to perform the anatomical-referencing of oral lesions. Results:27 consultations from 26 patients were evaluated for oral pathology lesions. 12 lesions were diagnosed as reactive, 5 were infectious lesions, 4 of vascular etiology, 3 pigmented lesions (amalgam tattoo and smoking-related melanosis) and 3 potentially malignant lesions. The most frequent location was the tongue with 8 cases, followed by the gingiva and jugal mucosa, each with 5 cases. Four lesions required biopsy and histopathological report. Conclusion: A teledentistry platform including digital representations of oral lesions using different digital markers, also associated with a mobile system to provide dental care, constitutes an excellent tool to treat patients that present oral lesions with potential cancer risk.

Objetivo: Avaliar o impacto da pandemia da covid-19 na realização de procedimentos diagnósticos para câncer de boca no Brasil. Método: Estudo transversal com dados do Sistema de Informações Ambulatoriais do Sistema Único de Saúde (SIA/SUS). A média de procedimentos diagnósticos registrados mensal, semestral e anualmente no período pré-pandemia (2016 a 2019) foi comparada, por meio da variação percentual, com a produção registrada no período pandêmico (2020). Resultados: Observou-se diminuição dos procedimentos de diagnóstico para o câncer de lábio e cavidade oral em 2020 comparado com o período de 2016 a 2019, com exceção das Regiões Sul e Centro-Oeste. A Região Nordeste apresentou a maior variação percentual negativa (-26,2%) entre a média de procedimentos realizados de 2016 a 2019 em comparação ao ano de 2020. Rondônia e Goiás apresentaram variação positiva, 66,2% e 43,5%, respectivamente. O país registrou as maiores reduções percentuais em abril (-43,2%) e em maio (-42,3%) de 2020, retornando à variação positiva apenas em dezembro (10,6%). Com exceção da Região Norte, o segundo semestre de 2020 foi pior do que o primeiro. Conclusão: A pandemia da covid-19 impactou a realização de diagnósticos de câncer de boca. Os achados indicam necessidade de orientações para profissionais de saúde e para a população sobre o caráter de urgência do diagnóstico de câncer de boca

Introduction: The identification and investigation of suspicious lesions in the oral cavity is crucial for the early diagnosis of oral cancer. The survival of diagnosed cases and the quality of life of the patients are directly affected by cancer treatment with a worse prognosis in advanced tumors. Objective: To evaluate the impact of the COVID-19 pandemic on the performance of diagnostic procedures for oral cancer in Brazil. Method: Cross-sectional study with data from the SUS Outpatient Information System (SIA-SUS). The average of diagnostic procedures recorded monthly, half-yearly and annually in the pre-pandemic period (2016 a 2019) was compared, through the percentage variation, with the production recorded in the pandemic (2020). Results: There was a drop in diagnostic procedures for cancer of the lip and oral cavity in 2020 compared to the period 2016 to 2019, with the exception of the South and Midwest regions. The Northeast region had the highest negative percentage change (-26.2%) among the average of procedures performed between 2016 and 2019 compared to 2020. Rondônia and Goiás showed positive variations, 66.2% and 43.5%, respectively. The country recorded the biggest percentage reductions in April (-43.2%) and in May (-42.3%) 2020, returning to positive variation only in December (10.6%). And with the exception of the North region, the second half of 2020 was worse than the first. Conclusion: The pandemic had an impact on the performance of oral cancer diagnoses. The findings indicate the need for guidance to health professionals and the population on the urgency of the diagnosis of oral cancer

Introduction: Oral squamous cell carcinoma (OSCC) is one of the most frequent cancers whose main causes are preventable because oral cavity is easily accessible for examination. OSCC involves many steps from the diagnosis until treatment which can result in late diagnosis and worst prognosis. Objective: Development and evolution of a Stomatology and Oral Pathology Service at the Federal University of Alfenas addressing early diagnosis and management of oral lesions. Method: Retrospective study developed with the files from 1998 to 2019. Data from all the cases diagnosed as oral malignancies were collected and the demographical, clinical, and microscope diagnosis were included. Results: 270 (84.64%) OSCC were found among 8,952 histopathological diagnoses. The patients age ranged from 24 to 94 years (mean 59.7±13.1 years), and more frequent in the sixth (32.3%) and seventh (26%) decades of life. Men were 2.5 times more affected than women. Most of patients were Caucasian (74.8%), and users of tobacco and alcohol. Over the years, there was an increase in the number of cases diagnosed and expansion of the area covered by the Service. Conclusion: The Dental Clinic (Stomatology) and Oral Pathology Laboratory has been playing an important role for the establishment and improvement of the healthcare system to the local population, mainly in rural áreas

Introdução: O carcinoma de células escamosas (CEC) de boca está entre os cânceres mais frequentes. Suas principais causas são evitáveis, pois a cavidade oral é uma área de fácil acesso para exame. No entanto, desde o estabelecimento do diagnóstico até o tratamento final dos pacientes, o CEC envolve muitas etapas e pode resultar em diagnóstico tardio e, portanto, em pior prognóstico para os pacientes. Objetivo: Apresentar o desenvolvimento e a evolução de um Serviço de Estomatologia e Patologia Oral da Universidade Federal de Alfenas, que tem como foco o diagnóstico precoce e o tratamento de lesões bucais. Método: Estudo retrospectivo com os prontuários de 1998 a 2019. Foram coletados dados de todos os casos diagnosticados como malignidades orais e incluídos os diagnósticos demográficos, clínicos e microscópicos. Resultados: Entre 8.952 diagnósticos histopatológicos realizados, 270 (84,64%) eram CCE. A idade dos pacientes variou de 24 a 94 anos (média 59,7±13,1 anos), sendo mais frequente na sexta (32,3%) e sétima (26%) décadas de vida. Os homens foram 2,5 vezes mais afetados do que as mulheres. A maioria dos pacientes era branca (74,8%) e o uso de tabaco e álcool, frequente. Ao longo dos anos, houve um aumento do número de casos diagnosticados, bem como uma ampliação da área de cobertura do Serviço. Conclusão: O Serviço de Estomatologia e Patologia Oral tem desempenhado um papel importante na implantação e melhoria do sistema de saúde da população local, principalmente nas Regiões interioranas e em áreas rurais

Introdução: Apesar das estratégias para prevenção e diagnóstico precoce, o câncer bucal está entre os mais incidentes no Brasil. Objetivo: Avaliar o conhecimento de cirurgiões-dentistas da Atenção Primária à Saúde sobre o câncer bucal. Material e método: Pesquisa censitária, exploratória e quantitativa, realizada em 2021. Cirurgiões-dentistas vinculados à rede pública dos 9 municípios da Baixada Litorânea/RJ preencheram um questionário com 41 questões, divididas em 5 blocos: 1. Perfil sociodemográfico, 2. Conhecimento sobre câncer bucal, 3. Fatores de risco para câncer bucal, 4. Segurança para diagnóstico do câncer bucal e 5. Experiência na identificação de lesões suspeitas. Resultado: Dos 128 cirurgiões-dentistas habilitados, 89,1% (n=114) participaram e caracterizavam-se por terem menos de 40 anos (50%), serem do sexo feminino (64,9%) e formados há mais de 16 anos (57,9%). Quanto ao conhecimento sobre o câncer bucal e fatores de risco, 84,2% consideraram seu nível de conhecimento regular ou bom e 65,8% consideraram baixo o seu nível de segurança para realização de procedimentos de diagnóstico do câncer bucal. Quanto à identificação de lesões suspeitas de câncer bucal, 86,8% realizavam exame da cavidade bucal, 7,9% não realizam porque o tempo da consulta é insuficiente e 5,3% porque não sabem fazer. Além disso, 50,9% identificaram alguma lesão suspeita nos últimos 12 meses. Notou-se também que 65,8% dos CDs não tinham conhecimento do fluxograma do município para diagnóstico e tratamento do câncer bucal. Conclusão: Os achados evidenciaram lacunas com relação ao conhecimento e procedimentos para diagnóstico precoce do câncer bucal.

Introduction: Despite the strategies for prevention and diagnosis, oral cancer is among the most incidents in Brazil. Objective: To evaluate the knowledge about oral cancer of primary health care dentists. Material and method: This is a census, exploratory and quantitative study carried out in 2021. Dentists linked to the public network of the 9 municipalities of the "Baixada Litorânea" region/RJ filled out a questionnaire with 41 questions, divided into 5 blocks: 1. Sociodemographic profile, 2. Knowledge on oral cancer, 3. Risk factors for oral cancer, 4. Safety for diagnosing oral cancer and 5. Experience in identifying suspicious lesions. Result: Of the 128 dentists, 89.1% (n=114) participated and were characterized by being less than 40 years old (50%), female (64.9%) and for having the dentistry degree for more than 16 years (57.9%). As for knowledge about oral cancer and risk factors, 84.2% considered their level of knowledge regular or good and 65.8% considered their level of security low for carrying out diagnostic procedures for oral cancer. Regarding the identification of oral cancer suspicious lesions, 86.8% performed oral cavity examination, 7.9% did not perform it because the consultation time was insufficient and 5.3% because they did not know how to do it. In addition, 50.9% have identified a suspicious lesion in the last 12 months. It was also observed that 65.8% of dentists were not aware of the municipality's flowchart for the diagnosis and treatment of oral cancer. Conclusion: The findings showed that the knowledge about oral cancer was satisfactory; however, training regarding risk factors and diagnostic procedures related to oral cancer should be strengthened.

Los tumores metastásicos en cavidad oral son pocos frecuentes, representan el 1% de las neoplasias malignas orales, son relativamente más frecuentes en los maxilares, respecto a aquellos localizados en los tejidos blandos orales. Se describe el caso de una paciente de 75 años de edad, con antecedentes de carcinoma renal de células claras, que consulta por la aparición repentina de una lesión tumoral en reborde alveolar superior izquierdo. Se realizó la biopsia exéresis con diagnóstico presuntivo de tumor metastásico o posible lesión reactiva. El informe anátomo - patológico confirma el diagnóstico de metástasis de un carcinoma renal. Las metástasis orales tienen un pronóstico generalmente malo, compromete la sobrevida, por lo que es importante realizar un exhaustivo estudio del paciente y considerar sus antecedentes, ya que en ocasiones son diagnosticadas tardíamentete.

Metastatic tumors to the oral cavity are rare, representing only 1% of malignant oral neoplasms. These metastatic tumors occur more frequently in the jaws than in soft oral tissues. This article describes the case of a 75-year-old patient with a history of clear cell renal carcinoma who seeks care because of the sudden appearance of a tumor lesion in the upper left alveolar ridge. An excision biopsy was performed with a presumptive diagnosis of a metastatic tumor or potential reactive lesion. The pathology report confirmed the diagnosis of renal cell carcinoma metastasis. Oral metastatic tumors usually present a bad prognosis with a low survival rate. It is important to examine patients thoroughly and consider their medical records, as they are sometimes diagnosed late.

Os tumores metastásicos na cavidade oral são raros, representam 1% das neoplasias malignas orais, sendo relativamente mais frequentes nos ossos maxilares enquanto aos localizados nos tecidos moles orais. Descreve-se o caso de uma mulher de 75 anos com história de carcinoma renal de células claras, que consultou com queixa de lesão tumoral localizada na crista alveolar superior esquerda. Uma biópsia foi feita com diagnóstico clínico presuntivo de tumor metastático ou possível lesão reativa. O laudo anátomopatológico confirmou o diagnóstico de metástase de carcinoma renal. As metástases orais geralmente têm um prognóstico ruim, com baixa sobrevivência, portanto é importante fazer um estudo exaustivo do paciente e tomar em conta sua história, já que às vezes o diagnóstico é tardio.

Diagnosis of oral and oropharyngeal cancer in advanced stages may be associated with social nature factors, access to health care, education, occupation, and behavioral/ cultural factors. Aim: To determine the factors related to high clinical-staging in patients diagnosed with squamous cell carcinoma in the oral and oropharyngeal region in a Cancer Center in Brazil between 2009 and 2015. Methods: It is an epidemiological, retrospective, and exploratory study. Patients diagnosed with squamous cell carcinoma had their medical records analyzed. The variables considered were sociodemographic, lifestyle, and disease characteristics. Descriptive and exploratory tests (Pearson's, chi-square test and, Student's t-test) were realized. Results: We analyzed 365 patient records, among which 289 (79.17%) were male, and 73 (20.0%) were female. Age ranged from 16 to 101 years, with a mean of 61.13. Regarding education, 157 (43.01%) studied < 8 years, 103 (28.21%) were illiterate and 102 (27.94%) studied > 8 years. 305 (83.56%) patients live in urban areas. There was an association between high clinical-staging and low educational level. For high clinical-staging, symptomatology, tobacco, and alcohol intake as well. Conclusion: Patients with low educational levels tend to report the disease later, and their diagnostics occurred in advanced stages. Thus, specific public health policies for this population, including access to dental care to recognize the clinical signs and early diagnosis, are necessary

Molecular changes that affect mitochondrial glycolysis have been associated with the maintenance of tumor cells. Some metabolic factors have already been described as predictors of disease severity and outcomes. This systematic review was conducted to answer the question: Is the glycolytic pathway correlated with the prognosis of oral squamous cell carcinoma (OSCC)? A search strategy was developed to retrieve studies in English from PubMed, Scopus, and ISI Web of Science using keywords related to squamous cell carcinoma, survival, and glycolytic pathway, with no restriction of publication date. The search retrieved 1273 publications. After the titles and abstracts were analyzed, 27 studies met inclusion criteria. Studies were divided into groups according to two subtopics, glycolytic pathways and diagnosis, which describe the glycolytic profile of OSCC tumors. Several components of tumor energy metabolism found in this review are important predictors of survival of patients with OSCC.

OBJECTIVE: Describe differences in pretreatment symptoms and the composition of symptom clusters in older patients with oral and oropharyngeal cancer. METHODS: In this cross-sectional study, quality of life (QoL) assessments for cancer patients (EORCT QLQ-C30 and QLQ-H & N35) were applied to 161 cases of oral and oropharyngeal cancer at the time of enrollment in an outpatient clinic. They were used to evaluate QoL-related symptoms reported by patients, according to their occurrence. To identify symptom clusters, an exploratory factor analysis (EFA) was performed, and the relationships between these clusters and independent variables were assessed with linear regression models. RESULTS: The most prevalent symptoms were pain (52%), worry (48%), and weight loss (44%). Five factors were extracted from the EFA, of which 3 were noteworthy. The dysphagia cluster was common to both cancer sites, although more frequent in oropharyngeal cancer patients, and included symptoms such as difficulty swallowing, pain, and weight loss. The psychological cluster included symptoms related to feeling worried, nervous, and depressed. The asthenia cluster, in addition to being age-related, may represent the advanced stage or progression of the disease. CONCLUSION: The dysphagia cluster loaded the most symptoms and was common to both cancers. In addition to pain (one of the main symptoms of the dysphagia cluster), psychological symptoms were also important in both groups of patients. Adequate and early control of these symptom clusters at diagnosis could favor better management of symptoms during treatment.

OBJETIVO: Descrever diferenças nos sintomas pré-tratamento e na composição de clusters de sintomas em pacientes idosos com câncer oral e orofaríngeo. METODOLOGIA: Neste estudo seccional, avaliações de qualidade de vida (QV) para pacientes com câncer (EORCT QLQ-C30 e QLQ-H & N35) foram aplicadas a 161 casos incidentes de câncer oral e orofaríngeo no momento da inscrição no ambulatório. Essas avaliações foram utilizadas para analisar os sintomas relatados pelos pacientes quanto à QV, de acordo com a ocorrência. Para identificar agrupamentos de sintomas, uma análise fatorial exploratória (AFE) foi realizada, e a relação entre esses agrupamentos de sintomas e variáveis independentes foi avaliada com modelos de regressão linear. RESULTADOS: Os sintomas mais prevalentes foram dor (52%), preocupação (48%) e perda de peso (44%). Cinco fatores foram extraídos do AFE, três dignos de nota. Embora mais relatado por pacientes orofaríngeos, o agrupamento de disfagia foi comum a ambos os locais de câncer e incluiu sintomas como dificuldade para engolir, dor e perda de peso. O agrupamento psicológico incluiu sintomas relacionados a sentir-se preocupado, nervoso e deprimido. O agrupamento da astenia, além de relacionado à idade, pode representar o estágio avançado ou progressão da doença. CONCLUSÕES: O cluster de disfagia carregou a maioria dos sintomas e foi comum a ambos os tipos de câncer. Além da dor, que era um dos principais sintomas desse cluster, os sintomas psicológicos também foram importantes em ambos os grupos de pacientes. O controle adequado e precoce desses grupos de sintomas no diagnóstico pode favorecer o melhor manejo dos sintomas durante o tratamento.

RESUMEN El linfoma de Burkitt, se trata de un subtipo poco frecuente del linfoma no Hodgkin, con elevada frecuencia en aquellos pacientes con sida. La hepatoesplenomegalia es un signo clínico de gran importancia para el diagnóstico oportuno de algunas patologías; entre los mecanismos de formación de la hepatoesplenomegalia se encuentra la infiltración celular, ocasionada por la migración de células tumorales. Se presenta por inflamaciones debido a la presencia de infecciones por virus o bacterias las cuales son muy comunes en pacientes con sida. Se presentó un caso de un paciente masculino de 4 años, diagnosticado con VIH positivo, con la configuración correspondiente de criterios clínicos en clasificación C para sida. El cual desarrolló a nivel de cavidad oral un Burkitt primario, que se acompañó de hepatoesplenomegalia. Se pretendió describir la relación y el comportamiento de este tipo de linfoma con la hepatoesplenomegalia, así como la repercusión a nivel del sistema estomatognático, a nivel sistémico y el plan de tratamiento. Por el cuadro clínico e inmunológico del paciente estudiado, se planteó un pronóstico reservado por presentar un cuadro clínico infrecuente, en el que se observó Burkitt; tanto a nivel del sistema estomatognático como a nivel abdominal. Se hizo necesario realizar un diagnóstico oportuno y certero para iniciar el tratamiento a tiempo, se comenzó inmediatamente con tratamiento (AU).

ABSTRACT Burkitt lymphoma (BL) is a rare subtype of non-Hodgkin lymphoma, with high frequency in those patients with AIDS. Hepatosplenomegaly is a clinical sign of great importance for the timely diagnosis of some pathologies; cellular infiltration is found among the mechanisms of hepatosplenomegaly formation; it is caused by the migration of tumor cells. It emerges by inflammations due to the presence of infections by virus or bacteria which are very common in patients with AIDS. The authors present the case of a male patient, aged 4 years, with a positive HIV diagnosis, and the correspondent configuration of clinical criteria in C classification for AIDS, who developed a primary Burkitt lymphoma at the level of oral cavity We present the case of a 4-year-old male patient diagnosed with HIV positive, with the corresponding configuration of clinical criteria in classification C for AIDS; who developed a primary LB at the oral cavity level that was accompanied by hepatosplenomegaly. The authors pretended to describe the relation and behavior of this kind of lymphoma with hepatosplenomegaly, and also the repercussion at the stomatognathic level, at the systemic level and the treatment plan. Due to the clinical and immunological characteristics of the studied patient a reserved prognosis was given because of presenting infrequent clinical characteristics in which a Burkitt was observed both, at the stomatognathic and at the abdominal level. It was necessary to make an opportune and accurate diagnosis to begin the treatment on time (AU).

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)
