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.

Análise do perfil clínico de pacientes portadores de neoplasia ocular escamosa atendidos em hospital referência de oculoplástica / Analysis of the clinical profile of patients with squamous ocular neoplasms attended at a reference hospital of oculoplastics

RESUMO Objetivo Analisar o perfil clínico de pacientes portadores de neoplasias escamosas da superfície ocular. Métodos Foram avaliados os principais fatores de risco envolvidos na gênese das neoplasias escamosas da superfície ocular, as características clínicas dos pacientes e os hábitos comportamentais associados. Foram incluídos neste trabalho de coorte histórica 80 pacientes com diagnóstico anatomopatológico de neoplasia escamosa da superfície ocular atendidos entre os anos de 2010 e 2020 em um hospital referência em oculoplástica e segmento anterior de Santa Catarina. Os dados clínicos e desfechos foram avaliados por meio da análise de prontuário e entrevista, sendo posteriormente tabulados no Excel e submetidos à analise estatística por meio do software Statistical Pakage for the Social Sciences, versão 16. Resultados Foi observado que 73,8% (n=59) eram do sexo masculino. A média de idade da amostra foi de 62 anos. Quanto ao fototipo de pele, de acordo com a escala de Fitzpatrick, constatou-se que a maioria apresentou os fototipos 1 e 2 (22; 27,5% e 44; 55%, respectivamente). Em relação à exposição ocupacional ao sol/radiação, 48% (n=60) apresentaram história de exposição ocupacional, sendo que, destes, 28 pacientes trabalhavam no setor de agricultura. Dos pacientes da amostra, 33 (41,2%) apresentavam histórico pessoal de neoplasias de pele, sendo que, destes, três apresentavam diagnóstico de xeroderma pigmentoso. Quanto ao hábito de uso de fatores de proteção solar, 61% (n=49) da amostra negou o hábito. Foi evidenciada associação estatisticamente significativa entre o hábito de usar fatores de proteção solar e histórico pessoal de neoplasias de pele. Em relação ao tipo de neoplasia escamosa, a maioria dos pacientes (72; 90%) apresentou diagnóstico anatomopatológico de carcinoma espinocelular ocular. Conclusão O perfil clínico epidemiológico dos pacientes portadores de neoplasias escamosas da superfície ocular neste estudo, predominantemente de carcinoma espinoceular ocular, foi de homens, idosos, de pele clara (fototipo 2) e com histórico importante de exposição aos raios solares ultravioleta A e B. Comorbidades imunodepressoras (HIV e transplante de órgão sólido) e doenças dermatológicas (albinismo e xeroderma pigmentoso) associaram-se ao aparecimento das neoplasias escamosas da superfície ocular em idade mais precoce. Em pacientes com histórico pessoal prévio de neoplasias de pele, foi evidenciado o hábito de uso de fatores de protetor solar mais presente em relação aos demais.

ABSTRACT Objective To analyze the clinical profile of patients with ocular surface squamous neoplasms (OSSN). Methods The main risk factors involved in the genesis of the ocular surface squamous neoplasms, the clinical features, and the behavioral habits associated were evaluated. This historical cohort study included 80 patients with anatomopathological diagnosis of OSSN who were treated between 2010-2020 at a reference hospital in oculoplastic and anterior segment in Santa Catarina. The clinical data and outcomes were evalated through the analysis of medical records and interviews, being later tabulated in Excel and analyzed using the SPSS 16 software. Results Regarding the clinical profile of the patients in the sample, 73.8% (n = 59) were male. The mean age of the sample was 62 years old. As for the skin phototype, according to the Fitzpatrick scale, most of the sample presented the phototype 1 and 2 (27.5% n = 22; and 55% n = 44 respectively). Regarding occupational exposure to the sun / radiation, 48% (n = 60) had history of occupational exposure, and of these, 28 patients worked in the agricultural area. Of the patients of the sample, 33 (41.2%) had a personal history of skin neoplasms, and of these, 3 had diagnosis of xeroderma pigmentosum. As for the habit of using sun protection factors, 61% (n = 49) of the sample denied the habit. A statistically significant association was evidenced between the habit of using sun protection factors and people's history of skin cancer. Regarding the type of squamous neoplasia, most patients in the 90% sample (n = 72) had an anatomopathological diagnosis of ocular squamous cell carcinoma. Conclusion The clinical epidemiological profile of patients with OSSN in this study, predominantly ocular squamous cell carcinoma, was men, elderly, fair-skinned (phototype 2) and with an important history of exposure to UVA and UVB rays. Immunosuppressive comorbidities (HIV, solid organ transplant) and dermatological diseases (albinism, xeroderma pigmentosum) are associated with the appearance of OSSN at an early age. In patients with a previous personal history of skin neoplasms, the habit of using sunscreen factors was more present than in the other patients.

Is there correlation between human papillomavirus (hpv) and esophageal epidermoid carcinoma? / Há correlação entre o papilomavírus humano (hpv) e o carcinoma epidermoide de esôfago?

ABSTRACT Background: Currently, persistent human papillomavirus (HPV) infection has been related in some geographic regions as a risk factor for esophageal squamous cell carcinoma. It results in the immunoexpression of the p16 protein, which has been used as marker of the oncogenic lineage by this etiological agent. Aim: To correlate epidemiological aspects of esophageal squamous cell carcinoma with the prevalence of HPV infection. Methods: Fifty-eight cases were analyzed and submitted to histopathological and immunohistochemical analysis by p16. Results: Of the 58 cases evaluated, 40 were men and 18 women, with a mean age of 63.2 years. p16 immunoexpression was positive in 46.55%. Conclusion: The prevalence of HPV infection is high in esophageal squamous cell carcinoma presenting in almost half of the cases (46.55%), without gender differentiation.

RESUMO Racional: Atualmente a infecção persistente pelo papilomavírus humano (HPV) tem sido relacionada em algumas regiões geográficas como fator de risco para o carcinoma epidermoide do esôfago. Ela resulta na imunoexpressão da proteína p16, que tem sido utilizada como marcadora da linhagem oncogênica por este agente etiológico. Objetivo: Correlacionar aspectos epidemiológicos do carcinoma epidermoide do esôfago com a prevalência de infecção pelo HPV. Métodos: Foram analisados 58 casos buscando-se perfil epidemiológico dos pacientes, com suas peças submetidas à análise histopatológica e imunoistoquímica pelo p16. Resultado: Dos 58 casos avaliados, 40 eram homens e 18 mulheres, com idade média de 63,2 anos. A imunoexpressão pelo p16 foi de 46,55%. Conclusão: A prevalência de infecção pelo HPV é alta no carcinoma epidermoide de esôfago apresentando-se em quase a metade dos casos (46,55%), sem diferenciação de idade quanto aos gêneros.

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)

Relationship between anemia and oral cancer: a case-control study

Abstract The aim of this study was to investigate the occurrence, type and severity of anemia at the time of diagnosis of oral cancer, and its potential association with the degree of tumor cell differentiation. This case-control study used 366 medical records of patients treated at two referral centers for oral cancer diagnosis, specifically: cases (n=70) with a histopathological diagnosis of oral squamous cell carcinoma (OSCC) of the oral cavity, and controls (n=296) with benign oral lesions. Sociodemographic, behavioral, and clinical variables of both groups, as well as complete blood count values, were analyzed by descriptive statistics and crude/adjusted logistic regression. Anemia was detected in 15.7% of the cases and 11.8% of the controls. The presence of anemia had an OR=1.64 (odds ratio) (95%CI 0.54-5.00) for OSCC, with no significantly statistical association. Normocytic anemia was the most prevalent form of anemia when oral cancer was diagnosed (91.4% of the controls and 72.7% of the cases), and moderate to severely low hemoglobin levels were associated with OSCC diagnosis (OR 6.49; 95%CI 1.18-35.24), albeit data on hematological examinations were missing.

Doenças de felinos domésticos diagnosticadas no sul do Rio Grande do Sul: estudo de 40 anos / Domestic feline diseases diagnosed in southern Rio Grande do Sul: a 40-year study

O objetivo deste estudo foi identificar as principais doenças de felinos na região sul do Rio Grande do Sul. Foram revisados os protocolos de necropsia e das amostras biológicas de felinos encaminhados ao Laboratório Regional de Diagnóstico da Faculdade de Veterinária da Universidade Federal de Pelotas (LRD/UFPel), no período de 1978 a 2018. Nesse período foram recebidas 1633 amostras de felinos, sendo 363 (22%) entre os anos de 1978 e 1999 e 1270 (78%) entre os anos de 2000 e 2018. Com relação aos diagnósticos, 457 felinos (28%) apresentaram tumores benignos ou malignos, sendo os tegumentares e os mamários os mais frequentes. As doenças bacterianas, fúngicas, virais, parasitárias, sem agente definido e as intoxicações totalizaram 554 casos (33,9%), destacando-se a esporotricose, com 12,8% dos diagnósticos. Concluiu-se que, na região sul do RS, o encaminhamento de felinos para diagnóstico aumentou significativamente após o ano 2000, comprovando que a espécie passou a ter maior importância como animal de companhia. Concluiu-se, também, que as neoplasias têm papel relevante entre as doenças de felinos e que a esporotricose é uma das mais importantes zoonoses na região.(AU)

The goal of this paper was to identify the main disease affecting felines in the southern region of Rio Grande do Sul. The necropsy protocols and feline biological materials submitted to the Regional Diagnostic Laboratory of the Veterinary College of the Federal University of Pelotas (LRD / UFPel) were reviewed, from 1978 to 2018. During this period 1633 feline samples were received, 363 (22%) between 1978 and 1999 and 1270 (78%) between 2000 and 2018. 59% of felines did not present a defined breed. As for diagnoses, 457 felines (28%) presented benign or malignant tumors, the most common being the integumentary and mammary tumors. Bacterial, fungal, viral, parasitic or undefined agent infections and intoxications were observed in 554 cases (33.9%), especially sporotrichosis with 12.8 % of the diagnoses. It was concluded that in southern RS the referral of cats for diagnosis increased significantly after the year 2000, proving that they became more significant as companion animals. It was also concluded that neoplasia play a relevant role among feline diseases, and that sporotrichosis is one of the most important zoonoses in the region.(AU)

Análisis de supervivencia de carcinoma escamoso de laringe en una cohorte retrospectiva chilena del Hospital Carlos Van Buren de Valparaíso / Survival analysis of laryngeal squamous cell carcinoma in a chilean retrospective cohort at the Carlos Van Buren Hospital of Valparaíso

Resumen Introducción: El cáncer laríngeo es una de las neoplasias de cabeza y cuello más frecuentes, asociado al envejecimiento y a los hábitos de vida. Los análisis de supervivencia de cáncer laríngeo en Chile son escasos. Objetivo: Calcular y analizar la supervivencia y las características clínicas del cáncer laríngeo en pacientes del Servicio de Otorrinolaringología del Hospital Carlos Van Buren, Valparaíso, Chile. Material y Método: Se realizó un estudio retrospectivo de cohorte, incluyendo pacientes diagnosticados con carcinoma escamoso de laringe entre 2007 y 2018. Se calculó la supervivencia con el método de Kaplan-Meier. Se aplicaron las pruebas de log rank, t de Student y exacta de Fisher. Resultados: Se incluyeron 211 pacientes, 90,52% hombres, con un promedio de edad de 68 años. El factor de riesgo más frecuente fue el tabaquismo. La ubicación tumoral más frecuente fue la glotis (59,44%) y el motivo de consulta más común la disfonía (52,66%). Un 70,48% presentó estadios avanzados. En 23,92% se realizó laringectomía total como tratamiento primario. La supervivencia global a 2 años fue de 86,6% en estadio precoz y 45,2% en estadio avanzado, mientras que a 5 años fue de 77,4% y 33%, respectivamente. Conclusión: La supervivencia estimada fue menor que en otros estudios nacionales, lo que puede asociarse al tamaño de la muestra analizada, a factores etarios y/o a mayor latencia de inicio de tratamiento. Se enfatiza el mejoramiento de los registros clínicos y la gestión sanitaria para un manejo oportuno.

Abstract Introduction: Laryngeal carcinoma is one of the most frequent head and neck neoplasms, being associated with ageing and lifestyles. In Chile, survival analyses of laryngeal carcinoma are scarce. Aim: To estimate and analyze the survival and clinical characteristics of laryngeal carcinoma in patients attended at the Otorhinolaryngology Department of the Carlos Van Buren Hospital, Valparaíso, Chile. Material and Method: We conducted a retrospective cohort study, including patients diagnosed with laryngeal squamous cell carcinoma between 2007 and 2018. Kaplan-Meier estimator was applied for survival analysis. Log rank test, Student's t-test and Fisher's exact test were applied. Results: 211 patients were included, 90,52% were men, with an average age of 68 years. The main risk factor was smoking (80%). The most frequent tumor location was in the glottis (59,44%) and the most frequent reason for consultation was dysphonia (52,66%). Most cases (70,48%) presented at advanced stages. Laryngectomy was performed as a primary treatment in 23,92%. The 2-year overall survival rate was 86,6% for early stages and 45,2% for advanced stages; the 5-year overall survival rate was 77,4% and 33%, respectively. Conclusion: The estimated survival rate was lower than those referred by other national studies, which may be associated with the analyzed sample size, age-related factors and/or period of latency until the beginning of treatment. We emphasize the necessity of an improvement in clinical records and the health management to the timely treatment.

Canine cutaneous neoplasms in the metropolitan region of Goiânia, Goiás state, Brazil / Neoplasias cutâneas caninas na região metropolitana de Goiânia, Goiás, Brasil

ABSTRACT: The present study aimed to describe the occurrence and epidemiological features of skin neoplasms diagnosed in dogs in the metropolitan region of Goiânia, Goiás state, Brazil. Diagnoses from dog biopsies from 2011 to 2016 provided by a private veterinary pathology laboratory were analyzed. The main diagnoses were mast cell tumor, hemangiosarcoma, squamous cell carcinoma, malignant melanoma, and hemangioma. Highest frequency of neoplasms was found in female dogs, dogs aged > 8 years, and purebred dogs, particularly the American Pit Bull Terriers and the Poodles. Most common sites affected by the neoplasms were the limb and the head. Using multiple correspondence analysis, groups of neoplasms were found to be associated with different epidemiological features and the size of the neoplasms was associated with the biological behavior. The results of this study described predispositions and verified the importance of different types of skin neoplasms in dogs in the region being studied.(AU)

O objetivo deste estudo foi determinar a prevalência e as características epidemiológicas das neoplasias cutâneas em cães na região metropolitana de Goiânia, Goiás. Foram analisados os diagnósticos de um laboratório do setor privado de 2011 a 2016. Mastocitoma, hemangiossarcoma, carcinoma de células escamosas, melanoma maligno e hemangioma representaram os principais diagnósticos. A maioria dos casos ocorreram em cães de raças definidas, fêmeas e com idade >8 anos. American Pit Bull Terrier e Poodle foram as raças mais encontradas. As neoplasias acometeram principalmente regiões de membros e cabeça. Pela análise de correspondência múltipla, associou-se os grupos de neoplasias com diferentes características epidemiológicas e o tamanho da neoplasia com o comportamento biológico. A comparação dos resultados com pesquisas prévias possibilitou confirmar predisposições previamente descritas e verificar a importância dos diferentes tipos de neoplasias cutâneas em cães na região estudada.(AU)

Frequency of conjunctival epithelial dysplasia in patients with pterygium / Incidência de displasia do epitélio conjuntival em pacientes com diagnóstico de pterígio

ABSTRACT Purpose: To determine the frequency of ocular squamous surface neoplasia associated with pterygium in an ophthalmology reference center in Central Mexico. Methods: We reviewed histopathological reports and slides of all patients who underwent pterygium surgery from 2014 to 2016 at the Instituto Mexicano de Oftalmologia in Queretaro (Mexico). Results: We studied 177 biopsy samples; 66% were from women, and the median age was 52 years. We found ocular squamous surface neoplasias in 11.29% (n=20) of the samples. One biopsy sample revealed a poorly differentiated keratinizing and infiltrating carcinoma. Conclusions: The prevalence of ocular squamous surface neoplasia in our region appears to be high. Countrywide studies are necessary to determine the true prevalence of ocular squamous surface neoplasia in Mexico and to examine related risk factors.

RESUMO Objetivo: Determinar a frequência de neoplasia escamosa da superfície ocular associada ao pterígio com apresentação clínica, em um centro de referência em Oftalmologia da região central do México. Métodos: Revisamos os laudos histopatológicos e as lâminas de biópsia de todos os pacientes que foram submetidos à cirurgia de pterígio de 2014 a 2016 no Instituto Mexicano de Oftalmologia, na cidade de Querétaro. Resultados: Estudamos 177 amostras de biópsia; 66% eram de pacientes do sexo feminino, sendo a mediana da idade de 52 anos. Encontramos neoplasia escamosa da superfície ocular em 11,29% (n=20). Uma amostra de biópsia mostrou um carcinoma queratinizante infiltrativo pouco diferenciado. Conclusões: A prevalência da neoplasia escamosa da superfície ocular nessa região parece ser maior do que a indicada por outras pesquisas. Mais estudos de âmbito nacional são necessários para determinar a verdadeira prevalência da neoplasia escamosa da superfície ocular no México e examinar os fatores de risco relacionados.

Studied variables: age, sex, place of birth and lived, personal pathological history, skin phototype, characteristics of the lesion, clinical dermatoscopic and histopathological diagnosis. Results: 5.9% of the elderly were diagnosed with skin cancer. It was more common in men (53.4%), range age from 60 to 79 (53.4%), were born or lived in urban areas and with skin phototype III (40.0%). 100.0% of the patients were exposed to sunlight, 86.7% without photo-protection means. The cancer was more localized in the face area (66.7%), had between 3 and 4 years of evolution (60.0%) and basal cell carcinoma (46.6%) was the most frequent. Clinical, dermatoscopic and histopathological diagnosis correlation was observed in 80.0 % of the cases. Conclusions: The rate of skin cancers in erderly is low, however, more attention is needed to ensure early diagnosis of this disease.

Profile of Laryngeal Microsurgeries in Patients Over 60 Years Old

Abstract Introduction The increase in life expectancy is an incentive to the development of researches with the elderly population aiming at actions that may ensure healthy and active aging. Objective To analyze the profile of laryngeal microsurgery performed in patients > 60 years old. Methods A retrospective observational study, with a cross-sectional design. A retrospective analysis of the medical records of elderly patients submitted to laryngeal microsurgery was performed at a private hospital in Curitiba, state of Paraná, Brazil, between January 2004 and December 2016. Were included all of the patients > 60 years old that underwent laryngeal microsurgery during this period. Results During the studied period, 213 laryngeal microsurgeries were performed in 181 patients > 60 years old. There was a preponderance of male patients. The mean age was 67.6 years old. Squamous cell carcinoma (SCC) was the most prevalent disorder (26%), followed by Reinke edema (20%), papillomatosis (14%), polyps (11%), leukoplakia (8%), minor structural alterations (8%), associated lesions (9%), and others (4%). Men presented a higher probability of SCC diagnosis, regardless of the age group, while Reinke edema was more frequently observed in women. A directly proportional relation between the frequency of laryngeal cancer and age increase was also observed. No significant differences were observed in professional voice users. Conclusion Further researches are required to properly comprehend the factors associ- ated with laryngeal lesions and determine prevention and treatment approaches.

Association between oral hygiene and head and neck cancer in Brazil / Associação entre higiene oral e câncer de cabeça e pescoço no Brasil

ABSTRACT: Introduction: Poor oral hygiene, regular use of mouthwash and absence of visits to the dentist could correspond to potential risk factors for the development of head and neck cancer. Objective: The objective of this study was to determine whether oral hygiene is associated with the occurrence of oral cavity and head and neck cancer in a Brazilian sample. Method: The variables of oral hygiene condition, such as toothbrushing frequency, dental loss, need and use of prosthesis, and regular visit to the dentist in a case-control study were analyzed in patients from five hospitals in the state of São Paulo, Brazil, paired by gender and age, from the multicenter project Genoma do Câncer de Cabeça e Pescoço (GENCAPO). Results: The most frequent malignancies in the 899 patients included were those of the tongue border (11.41%) and tongue base (10.92%). The multivariable statistical analysis found odds ratio values: Brushing once 0.33 (95%CI 0.25 - 0.44); Brushing twice 0.42 (95%CI 0.35 - 0.52); Flossing always 0.19 (95%CI 0.13 - 0.27); Flossing sometimes 0.19 (95%CI 0.15 - 0.24); Bleeding 2.40 (95%CI 1.40 - 4.09); Prosthesis 1.99 (95%CI 1.54 - 2.56); Visiting the dentist 0.29 (95%CI 0.22 - 0.37); Good hygiene 0.21 (95%CI 0.17 - 0.27); Regular hygiene 0.20 (95%CI 0.15 - 0.25); number of missing teeth (6 or more) 3.30 (95%CI 2.67 - 4.08). Conclusion: These data showed that, in the population studied, indicators of good hygiene such as brushing teeth and flossing were protective factors for mouth and head and neck cancer, while bleeding and many missing teeth were risk factors.

RESUMO: Introdução: Má higiene bucal, uso regular de enxaguante bucal e ausência de visitas ao dentista podem corresponder a potenciais fatores de risco para o desenvolvimento de câncer de cabeça e pescoço. Objetivo: Determinar se a higiene bucal está associada à ocorrência de câncer em cavidade oral e cabeça e pescoço em uma amostra brasileira. Método: O estudo caso controle analisou variáveis de higiene bucal, como frequência de escovação, perda dentária, necessidade e uso de prótese e visita regular ao dentista em pacientes de cinco hospitais do estado de São Paulo, pareados por sexo e idade, provenientes do projeto multicêntrico Genoma do Câncer de Cabeça e Pescoço (GENCAPO). Resultados: As neoplasias mais frequentes nos 899 pacientes incluídos foram: bordo de língua (11,41%) e base de língua (10,92%). A análise estatística múltipla encontrou os seguintes valores de odds ratio: escovar uma vez 0,33 (IC95% 0,25 - 0,44); escovar duas vezes 0,42 (IC95% 0,35 - 0,52); uso de fio dental sempre 0,19 (IC95% 0,13 - 0,27); uso de fio dental às vezes 0,19 (IC95% 0,15 - 0,24); sangramento 2,40 (IC95% 1,40 - 4,09); prótese 1,99 (IC95% 1,54 - 2,56), visita ao dentista 0,29 (IC95% 0,22 - 0,37); boa higiene 0,21 (IC95% 0,17 - 0,27); higiene regular 0,20 (IC95% 0,15 - 0,25); e número de dentes ausentes (6 ou mais) 3,30 (IC95% 2,67 - 4,08). Conclusões: Esses dados mostraram que, na população estudada, indicadores de boa higiene, como escovar os dentes e uso do fio dental, foram fatores de proteção para o câncer de boca e cabeça e pescoço, enquanto sangramento e muitos dentes ausentes foram fatores de risco.

Carcinoma epidermoide de lábio inferior: análise da incidência e mortalidade no Brasil / Lower lip epidermoid carcinoma: analysis of incidence and mortality in Brazil

O carcinoma epidermoide de lábios tem suas manifestações clínicas iniciais como atrofia, ressecamento e fissuras do vermelhão do lábio inferior com margem indefinida entre o vermelhão e a pele. O diagnóstico precoce é de fundamental relevância nos casos dessa patologia. O cirurgião dentista tem um papel extremamente importante neste caso. Objetivo: Realizar uma revisão da literatura pertinente sobre o carcinoma epidermoide oral. Metodologia: Essa revisão foi realizada empregando a base de dados do SCIELO, LALICS e BBO - Odontologia, foram pesquisados artigos da literatura com língua inglesa e portuguesa publicados no período de 2013 a 2018 com auxílio dos termos: câncer oral, diagnóstico e fatores associados. Foram excluídos os artigos cujas abordagens antes de 2013, outras línguas as não citadas, teses, projetos e produções não relacionadas a temática. Resultados: Os métodos tradicionais de tratamento oncológico são: cirurgia, radioterapia e a quimioterapia. O tratamento a ser estabelecido estará na dependência da localização, grau histológico de malignidade, estadiamento do tumor e da condição de saúde do indivíduo. Conclusões: O cirurgião-dentista deve estar preparado para diagnosticar e lidar com pacientes que apresentam lesões cancerizáveis com o propósito de diminuir as taxas de incidência e mortalidade e, então, melhorar a qualidade de vida das pessoas(AU)

Cancer is a cellular modification that is related to the loss of its metabolic regulation and intercellular control in which it differs depending on its type and behaves, biologically, different from a normal cell. From this point of view, lower lip cancer is one of the most frequent manifestations of oral cancer. The most frequent risk factors are stimulated from the practice of harmful habits such as: exposure to sunlight, alcohol consumption and smoking. Squamous cell carcinoma of the lips has its initial clinical manifestations such as atrophy, dryness and fissures of vermilion of the lower lip with indefinite margin between the vermilion and the skin. Early diagnosis is of fundamental relevance in cases of this pathology. The dentist surgeon plays an extremely important role in this case. The traditional methods of cancer treatment are: surgery, radiotherapy and chemotherapy. The treatment to be established will depend on the location, histological grade of malignancy, tumor staging and the individual's health condition. Therefore, the dental surgeon must be prepared to diagnose and deal with patients who have cancerous lesions in order to reduce incidence and mortality rates and thus improve people's quality of life(AU)

Laryngeal Cancer Attributable Factors and the Influence on Survival Rates: A Single Brazilian Institution Experience

Abstract Introduction Epidemiological studies focused on prognostic factors associated with laryngeal cancer in the Brazilian population are poorly reported in the literature. Objective To evaluate the influence of certain risk factors on the survival rates of patients with squamous cell carcinoma (SCC) of the larynx. Methods This retrospective study was conducted on adult patients who were admitted to the outpatient clinic of the head and neck department in a tertiary care hospital. Evaluation of the influence of risk factors on the survival rates of patients registered in the hospital with laryngeal SCC was performed based on age, sex, initial stage, time of evolution, habits, educational levels and relapse and death. Overall survival (OS), disease-free survival (DFS) and clinical-demographic data were analyzed using the Kaplan-Meier method, Log-rank test and Cox regression. Results A total of 107 patients with a mean age of 59.8 years (range 19-81) were included in this study. Stages III and IV were associated with decreased DFS (p = 0.02) and OS (p = 0.02). Smoking patients had a greater period of disease evolution than non-smoking patients (p = 0.003). Alcohol consumption in smokers increased the risk of death by 2.8 (p = 0.002) compared with non-drinking smokers. Male patients presented lower DFS average when compared with female patients (p = 0.04). Conclusion Our study confirms that male gender, smoking habit combined with alcohol consumption, and advanced stages were strongly associated with poor prognosis.

Caracterización clínico-patológica del cáncer esofágico avanzado en el Hospital Universitario Comandante Faustino Pérez. Matanzas / Clinic-pathologic characterization of the advanced esophagus cancer in the University Hospital Comandante Faustino Perez, Matanzas

RESUMEN Introducción: el cáncer de esófago en estadio avanzado, es uno de los más agresivos. En Cuba ocupa el décimo lugar entre las causas de muerte. Objetivo: caracterizar clínico y patológicamente a los pacientes con cáncer esofágico diagnosticados en el hospital estudiado. Materiales y métodos: se realizó un estudio prospectivo-descriptivo donde se efectuó una caracterización clínico-patológica a 59 pacientes con el diagnóstico endoscópico e histológico de cáncer de esófago, en el Hospital Faustino Pérez Hernández de Matanzas, de enero del 2016 a diciembre del 2017. Se estudiaron variables como: grupo etáreo, sexo, antecedentes patológicos personales y familiares, factores de riesgo, síntomas y signos predominantes en el diagnóstico, tiempo de aparición de los síntomas, tipo endoscópico, localización, tipo histológico, grado de diferenciación histológica, estadio de la enfermedad, tipo de tratamiento y tiempo de vida posterior al diagnóstico. Resultados: predominó el sexo masculino (88.1%) en pacientes mayores de 60 años (52.6%). La disfagia, la astenia y la anorexia fueron los síntomas más frecuentes; el etilismo crónico y el hábito de fumar fueron los factores de riesgo predominantes. La localización anatómica más frecuente fue el tercio medio (54.2%), el tipo endoscópico vegetante (88.1%) y el tipo histológico carcinoma epidermoide bien diferenciado (55.9%). Hubo relación entre el tiempo de inicio de los síntomas entre 3 y 6 meses antes del diagnóstico y el estadio IV de la enfermedad que predominó en 29 pacientes (49.2%). La mayoría de los pacientes recibieron tratamiento oncológico combinado con cirugía paliativa (47.5%) o ningún tratamiento (45.8%) pues el 50.8% de los pacientes fallecieron al mes del diagnóstico demostrando que el diagnóstico del cáncer esofágico se realiza casi siempre en estadios avanzados de la enfermedad cuando son posible pocas opciones terapéuticas. Conclusiones: el cáncer de esófago aún sigue diagnosticándose de forma tardía en estadios avanzados, con elevada prevalencia del carcinoma epidermoide sobre el adedocarcinoma que indica pocas acciones de salud preventivas sobre los factores de riesgo en la población estudiada, existiendo relación entre el estadio avanzado de la enfermedad y el poco tiempo de vida de estos pacientes posterior al diagnóstico.

ABSTRACT Introduction: the advanced-stage esophagus cancer is one of the most aggressive cancers. In Cuba, it is in the tenth place among the death reasons. Objective: to clinically and pathologically characterize the patients with esophageal cancer diagnosed in the mentioned hospital. Materials and methods: a prospective-descriptive study was carried out based on the clinical-histological characterization of 59 patients with the endoscopic and histological diagnosis of esophageal cancer in the Hospital "Faustino Pérez Hernández", of Matanzas, in the period from January 2016 to December 2017. The studied variables were: age group, sex, personal and familiar pathological antecedents, risk factors, symptoms and signs that were predominant in the diagnosis, time passed since the symptoms appeared, endoscopic kind, location, histological kind, level of histological differentiation, disease stage, kind of treatment, and life time after the diagnosis. Results: male sex predominated (88.1 %) in patients older than 60 years (52.6 %). Dysphagia, asthenia and anorexia were the most frequent signs. Alcoholism and smoking were the predominant risk factors. The most frequent anatomic location was the middle third (54.3 %); the endoscopic vegetating kind (88.1 %) and the histological kind well-differentiated epidermoid carcinoma (55.9 %) prevailed. The authors found a relation between the beginnings of the symptoms 3 to 6 months before the diagnosis and the disease IV stage predominating in 29 patients (49.2 %). Most of patients underwent oncologic treatment combined with palliative surgery (47.5 %) or no treatment (45.8 %), because 50.8 % of the patients died a month after the diagnosis, showing that the diagnosis of esophageal cancer is almost always achieved at advanced stages of the disease, when few therapeutic options are possible. Conclusions: esophageal cancer is still being diagnosed late, in advanced stages, with a higher prevalence of the epidermoid carcinoma over the adenocarcinoma. It indicates few health preventive actions on the risk factors among the studied population. There is a relation between the disease advanced stage and the few time patients live after the diagnosis.

Skin cancer incidence in rural workers at a reference hospital in western Paraná

Abstract BACKGROUND: Skin cancer is common in Brazil and is related to sun exposure, among other risk factors. There are no data on the incidence of malignant skin neoplasm in rural workers in western Paraná. OBJECTIVE: To analyze the incidence and profile of rural workers who were diagnosed with skin cancer at a reference service in Cascavel, western Paraná, in the last five years (2011-2016). METHODS: This retrospective cross-sectional study was carried out through a review of the anatomopathological reports of rural workers diagnosed with skin cancer at Cascavel Oncology Center (CEONC), in Cascavel. The following variables were collected: year of diagnosis, age, gender, injury location and histological subtype. RESULTS: A total of 681 cases of malignant epithelial neoplasia were identified, with a higher frequency in the 61-70 age group. Data analysis showed an increase of about 210% in the occurrence of skin cancers in the last 5 years. The cephalic region was the most affected, and the most common histological subtype was nodular basal cell carcinoma. There was no association between gender and location. STUDY LIMITATIONS: This is a retrospective study and analysis of a secondary data bank. CONCLUSION: This study is a regional estimation of the incidence of cutaneous neoplasms and provides evidence of a considerable increase in the number of diagnoses in rural workers from western Paraná, Brazil. Moreover, it is possible to conclude that the sample group studied is at risk of developing skin cancer.
