El pH salival como marcador biológico en pacientes diagnosticados con carcinoma epidermoide oral de Guantánamo / Salivary pH as diagnostic biomarker in patients diagnosed with oral squamous cells carcinoma in Guantanamo / pH salivar como marcador biológico em pacientes diagnosticados com carcinoma epidermóide oral de Guantánamo

RESUMEN Introducción: El cáncer bucal constituye un problema de salud de connotación mundial. Objetivo: Comparar las variaciones del pH salival entre pacientes con carcinoma epidermoide recién diagnosticados, después del tratamiento oncoespecífico y sujetos aparentemente sanos de la provincia Guantánamo, Cuba, en el período noviembre 2019- enero 2022. Método: Se realizó un estudio descriptivo, comparativo, transversal, en pacientes ambulatorios de la consulta de Cirugía Maxilofacial del Hospital General Docente "Dr. Agostinho Neto". El grupo de estudio estuvo conformado por 200 pacientes divididos en 3 subgrupos: subgrupo I (50 pacientes recién diagnosticados con carcinoma epidermoide oral, con diagnóstico concomitante de caries dental y periodontitis crónica del adulto); subgrupo II (50 pacientes con la referida patología después de tratamiento oncoespecífico, tratados por las enfermedades bucales antes citadas) y subgrupo III (100 pacientes controles aparentemente sanos). Se estudiaron las variables: edad, sexo, tipo de dieta y pH salival. Resultados: La edad media fue de 59,8 años, 70 % fueron hombres. Se asoció la dieta consumida y cada subgrupo (p=0,001). El pH salival de los pacientes con carcinoma epidermoide recién diagnosticados afectados por ambas enfermedades bucales fue ácido (6,25±0,37) en comparación a los otros subgrupos. El 98,6 % de los pacientes con pH salival ácido presentaron una dieta usual a base de carbohidratos y grasas (p=0,000). Conclusiones: Se evidenció que el pH salival de los pacientes con carcinoma epidermoide recién diagnosticados fue ácido en comparación a los otros subgrupos, por lo que este parámetro puede usarse como un marcador biológico de la enfermedad.

ABSTRACT Introduction: Oral cancer is a common health problem worldwide. Objective: Compare the salivary pH range changes among patients diagnosed recently with oral squamous cells carcinoma after receiving oncospecific treatment and subjects apparently healthy, Guantanamo, Cuba, period time November 2019 -January 2022. Method: A descriptive, comparative, cross-sectional study was carried out in outpatients of the Maxillofacial Surgery Consultation room at the Hospital General Docente "Dr. Agostinho Neto". The study group consisted of 200 patients divided into 3 subgroups: subgroup I (50 newly diagnosed patients with oral squamous cell carcinoma, with concomitant diagnosis of dental caries and chronic adult periodontitis); subgroup II (50 patients with the aforementioned pathology after oncospecific treatment, treated for the aforementioned oral diseases) and subgroup III (100 apparently healthy control patients). The following variables were studied: age, sex, type of diet and salivary pH. Results: Average age was 59.8 years, 70% were men. There was an association between the diet consumed and each subgroup (p= 0.001). The salivary pH of newly diagnosed squamous cell carcinoma patients affected by both oral diseases was acidic (6.25±0.37) compared to the other subgroups. The 98.6% of patients with acid salivary pH presented a usual diet based on carbohydrates and fats (p=0.000). Conclusions: It was shown that the salivary pH of newly diagnosed patients with squamous cell carcinoma was acidic compared to the other subgroups. Therefore, this parameter can be used as a biological marker of the disease.

RESUMO Introdução: O câncer bucal é um problema de saúde global. Objetivo: Comparar as variações do pH salivar entre pacientes com carcinoma espinocelular recém-diagnosticado, após tratamento oncoespecífico, e indivíduos aparentemente saudáveis da província de Guantánamo, Cuba, no período de novembro de 2019 a janeiro de 2022. Método: Estudo descritivo, comparativo, cruzado seccional, em pacientes ambulatoriais da consulta de Cirurgia Bucomaxilofacial do Hospital General Docente "Dr. Agostinho Neto". O grupo de estudo foi composto por 200 pacientes divididos em 3 subgrupos: subgrupo I (50 pacientes recém-diagnosticados com carcinoma espinocelular oral, com diagnóstico concomitante de cárie dentária e periodontite crônica do adulto); subgrupo II (50 pacientes com a patologia supracitada após tratamento oncoespecífico, tratados para as doenças bucais supracitadas) e subgrupo III (100 pacientes controles aparentemente saudáveis). As variáveis estudadas foram: idade, sexo, tipo de dieta e pH salivar. Resultados: A média de idade foi de 59,8 anos, 70% eram homens. A dieta consumida e cada subgrupo foram associados (p=0,001). O pH salivar de pacientes recém-diagnosticados com carcinoma espinocelular afetados por ambas as doenças bucais foi ácido (6,25±0,37) em comparação com os outros subgrupos. 98,6% dos pacientes com pH salivar ácido apresentaram dieta habitual baseada em carboidratos e gorduras (p=0,000). Conclusões: Evidenciou-se que o pH salivar dos pacientes com carcinoma espinocelular recém-diagnosticado foi ácido em relação aos demais subgrupos. Portanto, esse parâmetro pode ser utilizado como marcador biológico da doença.

Carcinoma epidermoide de piel tratado con HeberFERON®

RESUMEN Introducción: en la literatura biomédica son escasos los reportes sobre el uso de los interferones como tratamiento en el carcinoma epidermoide. En una unidad de atención primaria, en Colón, Matanzas, se implementó el HeberFERON® en este tipo de tumor, con experiencias favorables. Objetivo: describir la efectividad del HeberFERON® en el carcinoma epidermoide. Materiales y métodos: se realizó un estudio observacional, descriptivo en 33 lesiones de carcinoma epidermoide en 29 pacientes. La dosis fue de 7,0 y 10,5 MUI de actividad antiviral, infiltrada de forma perilesional tres veces por semana durante tres semanas. Se realizó el seguimiento clínico de los pacientes antes del tratamiento y a las 16 semanas del inicio del mismo. Las variables fueron: edad, sexo, fototipo de piel, procedencia, localización, tipo clínico, estadio y respuesta clínica al tratamiento. Se consideraron cuatro categorías de respuesta: completa, parcial, enfermedad estable y progresiva. Se incluyó la respuesta objetiva (completa más parcial). Se recogieron los datos en una historia clínica. Se utilizaron los programas Microsoft Excel y SPSS para el procesamiento estadístico. Resultados: el 65,5 % de los pacientes correspondió al sexo masculino. Un 58,6 % son fototipo II y de procedencia urbana. Predominaron las edades entre 61 y 80 años (55,2 %). Hubo respuesta objetiva en 57,6 % (cinco completas y 14 parciales). Las mejores respuestas la mostraron el carcinoma epidermoide queratósico superficial y el noduloulceroso. Conclusiones: la mezcla de interferones fue efectiva en el carcinoma epidermoide en todos los subtipos clínicos, aunque los autores sugieren un segundo ciclo de HeberFERON® o asociarlo con quimioterapia cuando la respuesta no sea completa.

ABSTRACT Introduction: there are few reports in the literature on the use of interferon in the treatment of the squamous cell carcinoma. In a primary care unit in Colon, Matanzas, HeberFERON® was implemented in this type of tumor with favorable experiences. Objective: to describe the effectiveness of HeberFERON® in epidermoid carcinoma. Materials and methods: an observational, descriptive study was conducted in 33 epidermoid carcinoma lesions in 29 patients. The doses were 7.0 and 10.5 MUI of antiviral activity, perilesionally infiltrated three times a week for three weeks. Clinical follow-up of patients was performed before the treatment and at 16 weeks from the beginning of the treatment. The variables were: age, sex, skin phototype, origin; location, clinical type, stage and clinical response to treatment. Four categories of response were considered: complete, partial, stable and progressive disease. The objective response (complete plus partial) was included. Data were collected in a clinical record. The Microsoft Excel and SPSS programs were used for statistical processing. Results: 65.5 % of patients were male. 58.6 % are phototype II and of urban origin. Ages ranging from 61 to 80 years (55.2 %) predominated. There was objective response in 57.6 % (five complete and 14 partials). The superficial keratotic squamous cell carcinoma and the nodular ulcerative one showed the best responses. Conclusions: interferon mixing was effective in all clinical subtypes of epidermoid carcinoma, although the authors suggest a second cycle of HeberFERON® or to associate it with chemotherapy when the response is not complete.

Epidermoid carcinoma of the hypopharynx in a child: a rare case report

Epidermoid carcinoma is a frequent tumor in the upper aerodiodestive tracts, and depending on its location and tumor, nodes, metastases(TNM)stage, its therapy and prognosis vary enormously. Its location in the hypopharynx is rare, and in children or young adolescents, this location is extremely rare; The incriminated causes and the pathophysiology of the development of these tumors at this age remain a mystery. We present the case of a young patient of 13 years old, followed for squamous cell carcinoma ofthe right piriform sinus, with contralateral synchronous tonsil localization, and right lateral cervical lymphadenopathy fixed at 5 cm. In the absence of existing guidelines on the management of this type of location at this age, a multi-disciplinary meeting was necessary to decide on the management of this difficult case at this age

Es una variedad de carcinoma metaplásico constituido por células pavimentosas queratinizantes. Se presenta el caso de un paciente de sexo masculino, de 65 años, de color de piel blanca, residente en el municipio Abreus, provincia Cienfuegos, que acudió a la consulta de mastología de la provincia por presentar una tumoración de 5 cms. en el cuadrante superior externo de la mama derecha, de dos meses de evolución. Se realizó exéresis de la tumoración y se recibió informe de la biopsia con el resultado de carcinoma epidermoide poco diferenciado. Actualmente el paciente se sigue en consulta y está libre de metástasis. Por lo inusual del caso se decide su publicación. Se presenta este reporte por ser el primer paciente de sexo masculino, operado de carcinoma epidermoide de mama en la provincia Cienfuegos.

ABSTRACT Primitive epidermoid carcinoma is considered the rarest breast tumor, with an incidence that represents only 0.04 to 0.05 % of all malignant tumors of this location. It is a variety of metaplastic carcinoma made up of keratinizing pavement cells. The case presented is a 65-year-old white male patient, resident in the Abreus municipality, Cienfuegos province who attended the province's mastology clinic for presenting a 5 cm tumor in the upper external quadrant of the right breast, two months in evolution. Exeresis of the tumor was performed and a report of the biopsy was received with the result of poorly differentiated squamous cell carcinoma. Currently the patient is followed in consultation and is free of metastases. Due to the unusual nature of the case, its publication is decided. This report is presented as the first male patient to undergo surgery for squamous cell carcinoma of the breast in the Cienfuegos province.

Cáncer de piel no melanoma en adultos mayores de hogares de ancianos, Guantánamo 2017-2019 / Nonmelanoma skin cancer in elderly at nursing homes of Guantanamo from 2017 to 2019

RESUMEN Introducción: En Guantánamo no se ha caracterizado el cáncer de piel en los adultos mayores. Objetivo: Caracterizar a los pacientes ingresados en los hogares de ancianos "Caridad Jaca" y "San José" de la ciudad de Guantánamo con diagnóstico de cáncer de piel en el periodo 2017-2019. Método: Se realizó un estudio observacional, prospectivo y transversal con todos los ancianos (n=256) con cáncer de piel (n=15). Se estudiaron las siguientes variables: edad, sexo, lugar de nacimiento y donde vivió, antecedentes patológicos personales, fototipo cutáneo, características de la lesión, diagnóstico clínico, dermatoscópico e histopatológico. Resultados: En el 5,9 % de los ancianos se diagnosticó un cáncer de piel. Fue más común en hombres (53,4 %), con 60 a 79 años (53,4 %), nacidos o que vivieron en áreas urbanas y fototipo cutáneo III (40,0 %). El 100,0 % se expuso a la luz solar, el 86,7 % sin medios de fotoprotección. El cáncer se localizó más en la cara (66,7 %), tenían entre 3 y 4 años de evolución (60,0 %) y el carcinoma basocelular (46,6 %) fue el más frecuente. En el 80,0 % de los casos se apreció correlación diagnóstico clínico, dermatoscópico e histopatológico. Conclusiones: Es baja la frecuencia del cáncer de piel en los ancianos, sin embargo, se requiere prestar más atención al aseguramiento del diagnóstico precoz de esta enfermedad.

ABSTRACT Introduction: Skin cancer in elderly has not been characterized in Guantanamo. Objective: Characterize the patients admitted to the nursing homes "Caridad Jaca" and "San José" in the city of Guantánamo with a diagnosis of skin cancer in the period 2017-2019. Method: It was conducted an observational, prospective and cross-sectional study with all the elderly (n=256) with skin cancer (n=15). 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.

Caracterización clinicoepidemiológica de pacientes con cáncer bucal y otras lesiones del complejo bucomaxilofacial / Clinical and epidemiological characterization of patients with oral cancer and other lesions of the bucomaxillofacial complex

Introducción: La mucosa bucal puede estar afectada por lesiones traumáticas, infecciones virales, micóticas y bacterianas, así como también por tumores benignos y malignos, malformaciones del desarrollo y enfermedades autoinmunes, genéticas y psicosomáticas, entre otras. Objetivo: Caracterizar clínica y epidemiológicamente a pacientes con cáncer bucal y otras lesiones del complejo bucomaxilofacial. Métodos: Se realizó un estudio descriptivo y transversal de 56 pacientes de ambos sexos, con alguna alteración morfológica evidente en el complejo bucomaxilofacial, atendidos en el Servicio de Estomatología del Policlínico Eduardo Mesa Llull del municipio II Frente de Santiago de Cuba, desde septiembre de 2015 hasta igual mes de 2017. Entre las variables analizadas figuraron: edad, sexo, color de la piel, localización anatómica, diagnóstico definitivo y tipo histológico. La información primaria se obtuvo de las entrevistas y de las historias clínicas. Por otra parte, se efectuó un examen físico exhaustivo y se tomó muestra para biopsia con vistas a diagnosticar las afecciones presentes. Resultados: En la casuística prevalecieron los pacientes de 35-59 años, los mestizos y el sexo femenino. Las zonas mayormente afectadas fueron la mucosa del carrillo y el labio inferior para el cáncer bucal y los rebordes alveolares residuales y la mucosa del carrillo para las otras lesiones. La leucoplasia bucal resultó el diagnóstico definitivo más común y el carcinoma epidermoide la variedad histológica preponderante. Conclusiones: La educación para la salud, la promoción y la prevención resultan primordiales en el mundo de la estomatología, de ahí que se impone evaluar y renovar los programas para que esta sea más preventiva y educacional.

Introduction: The oral mucosa can be affected by traumatic lesions, viral, fungal and bacterial infections, as well as by benign and, malignant tumors, development malformations and autoinmmune genetic and psychosomatic diseases, among others. Objective: To characterize clinically and epidemiologically patients with oral cancer and other lesions of the bucomaxillofacial complex. Methods: A descriptive and cross-sectional study of 56 patients of both sexes, with some evident morphological change in the bucomaxillofacial complex, assisted in the Stomatology Service of Eduardo Mesa Llull Polyclinic, II Frente municipality in Santiago de Cuba was carried out from September, 2015 to the same month in 2017. Among the analyzed variables there were: age, sex, skin color, anatomical localization, definitive diagnosis and histological type. The primary information was obtained from the interviews and of the medical records. On the other hand, an exhaustive physical examination was made and a sample for biopsy was taken with the aim of diagnosing the present disorders. Results: The 35-59 years patients, mestizos and the female sex prevailed in the case material. The most affected areas were the cheek mucosa and the lower lip for the oral cancer and the residual alveolar edges and the cheek mucosa for the other lesions. Oral leukoplakia was the most common definitive diagnosis and the carcinoma epidermoid the preponderant histological variety. Conclusions: Health education, promotion and prevention, are essential in the Stomatology environment, so that it is imperative to evaluate and renew programs for they to have more influence on education and prevention.

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.

Dellen corneal secundario a carcinoma epidermoide de conjuntiva / Corneal dellen secondary to epidermoid carcinoma of the conjunctiva

El dellen corneal es un área de adelgazamiento corneal localizado como consecuencia de la deshidratación provocada por la falta de humectación relacionada con una zona adyacente de abultamiento conjuntival. Se presenta una paciente femenina de 72 años, blanca, con antecedentes de hipertensión arterial, quien refirió lagrimeo y sensación de cuerpo extraño en el ojo izquierdo, de una semana de evolución. Al examen biomicroscópico se observó tejido fibrovascular en conjuntiva bulbar nasal que infiltraba la córnea, sobreelevado, de superficie lisa, no queratinizada, acompañada de inyección conjuntival y múltiples neovasos. En la córnea periférica y adyacente a esta se observó depresión de base limpia, redondeada, de 6 mm de extensión y profundidad hasta estroma anterior. Teniendo en cuenta las características de la lesión, se planteó como diagnóstico presuntivo dellen corneal secundario a pterigium grado II sintomático. La biopsia informó carcinoma de células escamosas, moderadamente diferenciado, asociado con un extenso infiltrado inflamatorio a predominio de linfocitos(AU)

Corneal dellen is an area of localized corneal thinning as a result of dehydration caused by lack of humectation associated to an adjoining conjunctival bulging. Here is a 72-years old Caucasian woman with a history of hypertension, who presented continuous tearing and feeling of a foreign body in her left eye during a week. The biomicroscopic exam showed fibrovascular tissue in nasal bulb conjunctiva, which infiltrated into the cornea, it was raised of flat surface, unkeratinized, accompanied with conjunctival injection and multiple neovessels. In the peripheral cornea and adjacent to it, there was a clean, rounded depression measuring 6 mm of extension and depth up to the anterior stroma. The presumptive diagnosis was corneal dellen secondary to symptomatic grade II pterygium. The biopsy yielded the presence of squamous cell carcinoma, moderately differentiated, and associated with extensive inflammatory infiltrate with predominance of lymphocytes(AU)

Sobrevida e fatores prognóstico do Carcinoma Epidermóide de Boca e Orofaríngeo: análise de 1776 casos / Survival and prognostic factors of oral and oropharyngeal squamous cell carcinoma: analysis of 1776 cases

O carcinoma epidermóide (CE), destaque para o de boca (CEB) e orofaríngeo (CEOf), é o tipo de câncer mais frequente na região de cabeça e pescoço, com mais de 90% de apresentação nessas regiões, representando 6% de todos os carcinomas. Avaliação epidemiológica dessa patologia com base populacional ainda é escassa e essa neoplasia é um problema de saúde pública no Brasil e no mundo. Diante desses fatos, este estudo tem o propósito de descrever e analisar a sobrevida com destaque para os principais fatores associados ao seu prognóstico. Para isso foi realizado um estudo de prognóstico retrospectivo em bancos de dados e prontuários, onde foram selecionados todos os casos com diagnóstico de CEB e CEOf da Liga Norte Riograndense Contra o Câncer, dos últimos 11 anos. As sobrevidas foram calculadas com Kaplan-Meier e comparação das funções com Log-Rank. Os riscos calculados em modelos univariados de Cox e modelos preditivos na análise multivariada de Cox. Para Sobrevida Livre da Doença (SLD) do CEB destacaram-se como fatores de pobre prognóstico, o Sistema de Gradação Histopatológica de Malignidade (SGHM) da Organização Mundial da Saúde (OMS) em pouco diferenciada, localização na região retromolar, não ter companheiro conjugal, estadiamento avançados e tratamentos mais complexos. Essas características se repetiram na Sobrevida Global (SG) para CEB, com exceção do estado conjugal atual. Na SG do CEOf, a localização em base de língua e o consumo de álcool obtiveram os piores prognósticos. Já para SLD do CEOf, o SGHM OMS em pouco diferenciado, tabagismo e não ter companheiro conjugal, obtiveram os piores prognósticos. O SGHM OMS parece ser um fator prognóstico eficaz para o CEB. Não ter companheiro pode comprometer a SLD (CEB e CEOf), com repercussão na qualidade de vida do paciente, adesão e manutenção do tratamento. Os fatores de riscos já bem estabelecidos, como consumo de álcool e fumo, parecem se comportar como fatores prognóstico importantes no CEOf, mas devem ser abordados com cautela, principalmente quando não verifica-se o tipo, tempo e quantidade utilizados. Mesmo com a melhora na sobrevida do CEO e CEOf mediante avanços no tratamento, ela ainda preocupa a medida que aumenta a dificuldade do diagnóstico (Lábio>Oral>Orofaringe). Tanto para CEB como para o CEOf as sobrevidas foram consideradas medianas, reafirmando fatores prognósticos já bem estabelecidos, como estadiamento clínico e localização, outros ainda controversos, como SGHM, habito de fumar e de beber, ganharam força como fatores prognósticos independentes e um coadjuvante inesperado, o estado conjugal atual (AU).

The most common type of cancer in the head and neck region is the squamous cell carcinoma (SCC), which is more frequent in the mouth (SCCM) and oropharyngeal (SCCO), with a presentation of more than 90% in these regions, representing 6% of all carcinomas. Epidemiological evaluation of this population-based pathology is still scarce and this neoplasm is a public health problem in Brazil and in the world. Faced with these facts, this study aims to describe and analyze survival, highlighting the main factors associated with its prognosis. For this, a retrospective prognostic study was carried out in databases and medical records, where all the cases diagnosed with SCCM and SCCO of the North League Riograndense Against Cancer of the last 11 years were selected. Survival were calculated with Kaplan-Meier and comparison of functions with Log-Rank. The risks calculated in univariate Cox models and predictive models in the multivariate analysis of Cox. For SCCM's Disease Free Survival (DFS) the poor prognostic factors, the histopathological gradation system of malignancy (HGSM) of the World Health Organization (WHO) in little differentiated, location in the retromolar region, not having conjugal companion, advanced staging and more complex treatments. These characteristics were repeated in the Global Survival (GS) for SCCM, with the exception of the current marital status. In the GS of the SCCO, localization in basis of language and alcohol consumption obtained the worst prognoses. Already for DFS of SCCO, the HGSM in little differentiated, smoking and having no marital partner, obtained the worst prognoses. The HGSM appears to be an effective prognostic factor for SCCM. Not having a partner can compromise DFS (SCCM and SCCO), with repercussion on patient's quality of life, adherence and maintenance of treatment. Wellestablished risk factors, such as alcohol and smoking, seem to be important prognostic factors in SCCO, but should be approached with caution, especially when the type, time, and quantity used are not checked. Even with the improvement in the SCCM's and SCCO's survival through advances in treatment, she is still worrisome, as the difficulty of diagnosis increases (Lip> Oral> Oropharynx). Both SCCM and SCCO were considered median, reaffirming already well established prognostic factors, such as clinical staging and localization, others still controversial, such as HGSM, smoking and drinking habits, gained strength as independent prognostic factors and an unexpected coadjutant, the current marital status. Keywords: Epidermoid carcinoma; mouth; oropharynx; prognosis (AU).

Evaluation of the cryosurgery for treatment of squamous cell carcinoma in cats / Avaliação da criocirurgia no tratamento do carcinoma de células escamosas em gatos

The cryosurgery is a very useful therapy for the treatment of a variety of neoplastic and non-neoplastic processes. Nevertheless, it is still poorly described as an option for the treatment of specific cutaneous neoplasms, such as squamous cell carcinoma. The purpose of the present study was to analyze the clinical response of cryosurgery for the treatment of squamous cell carcinoma in cats. For this 13 squamous cell carcinoma lesions were selected in 11 cats, diagnosed through citopathological and/or histopathological examinations. The lesions were frozen using liquid nitrogen spray, and the evaluations were performed in the moment of freeze and approximately every 15 days until the wound was completely healed. The response of cryosurgery was considered complete with tumoral remission on 38.5% of the cats, and partial on 46.1%. The main complications included crusting and nostril stenosis. The presented results suggested that cryosurgery is effective and may be a viable option for the treatment of squamous cell carcinoma in cats. The effectiveness of the therapy; however, depends on the correct selection of the candidates for cryosurgery based on the lesion size, and the attendance to some criteria, such as the freezing time and post-operative care.(AU)

A criocirurgia tem se mostrado uma terapia de grande auxílio no tratamento de uma variedade de processos neoplásicos e não neoplásicos. Apesar disso, ainda é pouco descrita a utilização da criocirurgia como opção de tratamento de neoplasias cutâneas específicas, como o carcinoma de células escamosas. Objetivou-se com o presente estudo analisar a resposta clínica da criocirurgia para o tratamento do carcinoma de células escamosas em gatos. Para isso, foram selecionadas 13 lesões do tipo carcinoma de células escamosas em 11 gatos, diagnosticadas por meio de análise citopatológica e/ou histopatológica. As lesões foram congeladas por meio de nitrogênio líquido na forma de spray, e as avaliações realizadas no momento do congelamento e aproximadamente a cada 15 dias, até a completa cicatrização da ferida. A resposta da criocirurgia foi considerada completa, com remissão tumoral em 38,5% dos gatos e parcial em 46,1% destes. As principais complicações verificadas incluíram a formação de crostas e estenose de narina. Os resultados apresentados no presente estudo sugerem que a criocirurgia é efetiva e pode ser uma opção viável para o tratamento do carcinoma de células escamosas em gatos. O sucesso do tratamento, entretanto, depende da correta seleção dos candidatos à técnica quanto ao tamanho da lesão, e do atendimento a alguns critérios, como o tempo de congelamento e os cuidados pós-operatórios.(AU)

Carcinoma epidermoide de la lengua: presentación de un caso / Epidermoid carcinoma of the tongue: report of a case

El carcinoma epidermoide es el cáncer bucal más frecuente que representamás de 90% de todos los tipos de cáncer de la cavidad oral. Se presenta el caso de masculino de 41 años de edad con un carcinoma epidermoide de rápida evolución a nivel de la lengua. Se observó una estomatosis localizada en el borde izquierdo de la lengua caracterizada por una neoformación de bordes elevados indurados, centro ulcerado, de 2 cm de diámetro y friable. Se detectaron adenomegalias del lado izquierdo de 2 cm. El paciente refería dolor a nivel del cuello y a niveldel oído izquierdo. Fumaba hasta dos cajetillas de cigarros al día. El estudio histopatológico reveló un carcinoma epidermoide ulcerado, invasor con áreas moderadamente poco diferenciadas. Se inició tratamientocon radioterapia 25 sesiones y quimioterapia con cisplatino. Se determinó mala tolerancia y respuesta al tratamiento establecido, por lo que éste se suspendió y se optó por tratamientos paliativos. La evolución del paciente fue tórpida y falleció a los 10 meses del diagnóstico. Las neoplasias de la cavidad oral son relativamente poco frecuentes, pero la letalidad alcanza hasta 78 por ciento entre las neoplasias de las vías aerodigestivas superiores y se diagnostican en etapas avanzadasen 65 por ciento de los casos. La prevención es fundamental, sobre todo la supresión del tabaquismo.

Epidermoid carcinoma is the most frequent oral cancer (90% of alloral cancer). We present the case of a 41-year-old man with oralcancer on the tongue. The lesion was localized on the left side of thetongue and was characterized by an ulcerated tumor with induratedborders, 2 cm of diameter. Lymph node metastasis was detected onthe neck. The patient had left ear pain and also a pain in the neck.He smoked two packs of cigarettes per day. The histopathologic studyrevealed an epidermoid carcinoma with poor and well-diff erentiatedareas. Radiotherapy and chemotherapy with cisplatin on were started.The patient did not tolerate and had a poor response, so the treatmentwas suspended. The patient died 10 months after the diagnosis. Oralcarcinoma is not frequent but the mortality is high, 78%, between thecarcinomas of the aerodigestive tract and frequently it is diagnosedwhen in advanced stages in 65% of the cases. The most important arethe prevention, mostly, tobacco consumption.

Sarcoma fusocelular de laringe / Fusocellular sarcoma of the larynx

El cáncer representa un problema de salud a nivel mundial dentro de las enfermedades crónicas no trasmisibles y es una de las primeras causas de muerte en la sociedad actual. El cáncer de laringe forma parte de los tumores malignos de cabeza y cuello, siendo el tipo histológico más frecuente el carcinoma epidermoide, tiene como ubicación más frecuente la glotis y aparece raramente en menores de 40 años. Por otra parte los sarcomas que se originan en la cabeza y el cuello son neoplasias malignas muy poco frecuentes, correspondiendo al 1 por ciento de las neoplasias malignas de esta región y al menos del 10 por ciento de todos los sarcomas del organismo. Se realiza la presentación de un caso de un paciente de 21 años con el diagnóstico histológico de sarcoma fusocelular subglótico, lo cual resulta interesante tomando en cuenta que la edad del paciente, así como el tipo histológico y la ubicación del tumor, no son frecuentes en nuestras consultas(AU)

Cancer represents a global health problem within non-communicable chronic diseases and is one of the leading causes of death in today's society. Laryngeal cancer forms part of malignant tumors of the head and neck, the most common histological type being epidermoid carcinoma, which is more frequently located in the glottis and rarely appears under 40 years. On the other hand sarcomas originating in the head and neck are very rare malignancies, corresponding to 1 percent of the malignancies of this region and at least 10 percent of all the sarcomas of the organism. The presentation of a case of a 21-year-old patient with the histological diagnosis of subglottic fusocellular sarcoma is presented, which is interesting considering that the patient's age, as well as the histological type and the location of the tumor, are not a case frequent in our consultations(AU)

Cytotoxic Effect of Thymus caramanicus Jalas on Human Oral Epidermoid Carcinoma KB Cells

Abstract Identifying new chemotherapeutic agents with fewer side effects is a major concern for scientists today. Thymus caramanicus Jalas (Lamiaceae family) is one of the species of Thymus that grows wild in different regions of Iran. Traditionally, leaves of this plant are used in the treatment of diabetes, arthritis and cancer. Here was investigated the cytotoxic property of Thymus caramanicus essential oil and extract in human oral epidermoid carcinoma KB cells. Cell viability was measured by MTT and neutral red assays. The cells were exposed to different concentrations of essential oil (0.05-1 µL/mL) and extract (25-150 µg/mL) for 24 h. Doxorubicin was used as anticancer control drug. The data showed that the essential oil (IC50=0.44 µL/mL) and extract (IC50=105 µg/mL) induce potent cytotoxic property. Surprisingly, cytotoxic effects of essential oil and extract of this plant on KB cancer cells were greater than those on normal gingival HGF1-PI1 cell line. In addition, Thymus caramanicus could potentiate the effect of doxorubicin in sub-effective concentrations. The results of the present study indicate that essential oils and extracts of Thymus caramanicus have potential anti-proliferative property on KB cells and can be used as pharmaceutical case study for oral cancer treatments.

Resumo A identificação de novos agentes quimioterápicos com menos efeitos colaterais é uma grande preocupação para os cientistas de hoje. Thymus caramanicus Jalas (família Lamiaceae) é uma das espécies de Thymus que cresce selvagem em diferentes regiões do Irã. Tradicionalmente, as folhas desta planta são utilizados no tratamento da diabetes, artrite e câncer. Aqui investigamos a propriedade citotóxica do óleo essencial e extrato de Thymus caramanicus em células da linhagem celular tumoral humana de carcinoma epidermóide de boca (KB). A viabilidade celular foi medida por ensaios MTT e vermelho neutro. As células foram expostas a diferentes concentrações de óleo essencial (0,05-1 μL/mL) e extrato (25-150 μg/mL) durante 24 h. A doxorrubicina foi utilizada como droga de controle anticâncer. Os dados mostraram que o óleo essencial (IC50 = 0,44 μL/mL) e o extrato (IC50 = 105 μg/mL) induzem uma potente propriedade citotóxica. Surpreendentemente, os efeitos citotóxicos de óleo essencial e extrato desta planta sobre células cancerígenas KB foram maiores que sobre a linhagem celular gengival normal HGF1-PI1. Além disso, Thymus caramanicus poderia potencializar o efeito da doxorrubicina em concentrações sub-efetivas. Os resultados do presente estudo indicam que óleos essenciais e extratos de Thymus caramanicus têm potenciais propriedades anti-proliferativas sobre células KB e podem ser usado como estudos de caso farmacêuticos para tratamentos de câncer bucal

Distribution in the body of targeted ursolic acid liposomes and their inhibitory effect on mice transplanted tumor / 中国药学杂志

OBJECTIVE: To study the distribution of folate receptor targeted ursolic acid liposomes and evaluate its antitumor effects on human epidermoid carcinoma xenografts in nude mice. METHODS: Folate derivative was used as targeting molecule and conjugated with mPEG-DSPE for obtaining liposome with long circulation features. This novel targeted agent was prepared by a thin-film dispersion method and ursolic acid was loaded into the liposomes as the anticancer drugs. Tissue distribution of liposomes in heart, liver, spleen, stomach, kidney and tumor were investigated. The antitumor effect of the targeted ursolic acid liposomes (F-PEG-L-UA) on human epidermoid carcinoma xenografts in nude mice was also studied. RESULTS: Compared with free ursolic acid liposome, UA liposome was slowly removed from blood circulation and the concentration of F-PEG-L-UA in liver, kidney and tumor tissue is significantly higher than other groups. The growth speed of tumor in the group of F-PEG-L-UA was significantly slowed down compared with other groups. The tumor volume in F-PEG-L-UA group was about 50% reduction compared with PBS-treated mice (P<0.05). CONCLUSION: A novel targeted ursolic acid compound is synthesized as the folate receptor targeting functional material. It has obvious inhibitory effect on human epidermoid carcinoma xenografts and it might be an effective antitumor drug delivery system.
