Cancer cell membrane (CCM) derived nanotechnology functionalizes nanoparticles (NPs) to recognize homologous cells, exhibiting translational potential in accurate tumor therapy. However, these nanoplatforms are majorly generated from fixed cell lines and are typically evaluated in cell line-derived subcutaneous-xenografts (CDX), ignoring the tumor heterogeneity and differentiation from inter- and intra- individuals and microenvironments between heterotopic- and orthotopic-tumors, limiting the therapeutic efficiency of such nanoplatforms. Herein, various biomimetic nanoplatforms (CCM-modified gold@Carbon, i.e., Au@C-CCM) were fabricated by coating CCMs of head and neck squamous cell carcinoma (HNSCC) cell lines and patient-derived cells on the surface of Au@C NP. The generated Au@C-CCMs were evaluated on corresponding CDX, tongue orthotopic xenograft (TOX), immune-competent primary and distant tumor models, and patient-derived xenograft (PDX) models. The Au@C-CCM generates a photothermal conversion efficiency up to 44.2% for primary HNSCC therapy and induced immunotherapy to inhibit metastasis via photothermal therapy-induced immunogenic cell death. The homologous CCM endowed the nanoplatforms with optimal targeting properties for the highest therapeutic efficiency, far above those with mismatched CCMs, resulting in distinct tumor ablation and tumor growth inhibition in all four models. This work reinforces the feasibility of biomimetic NPs combining modular designed CMs and functional cores for customized treatment of HNSCC, can be further extended to other malignant tumors therapy.

Spatialomics is another research hotspot of biotechnology after single-cell sequencing technology, which can make up for the defect that single-cell sequencing technology can not obtain cell spatial distribution information. Spatialomics mainly studies the relative position of cells in tissue samples to reveal the effect of cell spatial distribution on diseases. In recent years, spatialomics has made new progress in the pathogenesis, target exploration, drug development and many other aspects of head and neck tumors. This paper summarizes the latest progress of spatialomics in the diagnosis and treatment of head and neck cancer.

RESUMO Objetivo Investigar o impacto da mucosite hipofaríngea quimiorradioinduzida na deglutição e o seu manejo, a partir de uma revisão integrativa de literatura. Estratégia de pesquisa A busca e a seleção dos artigos foram realizadas nas seguintes bases de dados: PubMed, Embase, Scopus, ScienceDirect e LILACS. Critérios de seleção Os termos de busca utilizados foram ''Pharyngeal Mucositis", ''Radiotherapy" e ''Esophagitis", com auxílio do operador booleano (AND). A equação de busca utilizada foi: ''Pharyngeal Mucositis" AND "Radiotherapy" AND "Esophagitis". A seguinte questão central orientou o estudo: "Qual a forma de avaliação e manejo da mucosite hipofaríngea induzida pela radiação na região de cabeça e pescoço e seu impacto na deglutição?". Resultados Foram identificados 75 estudos, sendo que 6 foram excluídos devido à duplicidade e 60 foram excluídos por não se encaixarem nos critérios de inclusão; os artigos restantes foram lidos na íntegra e 4 foram selecionados para fazerem parte desta revisão integrativa da literatura. Conclusão Apesar da escassa literatura e das poucas informações sobre os métodos de avaliação da mucosite hipofaríngea, os artigos apontam que, independentemente da dose de radiação, a radioterapia na região cervical causa mucosite hipofaríngea. A mucosite hipofaríngea provoca grande impacto na deglutição, resultando na necessidade de uso de via alternativa de alimentação. Além da ausência de informações quanto à avaliação e graduação da mucosite hipofaríngea, os estudos não discutem o tratamento direto ou a prevenção desse tipo de doença.
ABSTRACT Purpose To investigate the impact of chemoradiation-induced hypopharyngeal mucositis on swallowing and its management, based on an integrative literature review. Research strategy Two researchers were responsible for the search and selection of articles, within the following databases: PubMed, Embase, Scopus, Science Direct, and Lilacs. Selection criteria The search terms used were "Pharyngeal Mucositis", "Radiotherapy" and "Esophagitis", with the aid of the Boolean operator (AND). The search equation used was "Pharyngeal Mucositis" AND Radiotherapy AND Esophagitis. The following central question guided the study: "What is the assessment and management of radiation-induced hypopharyngeal mucositis in the head and neck region and its impact on swallowing?" Results 75 studies were identified, of which 6 were excluded due to duplicity and 60 were excluded for not meeting the inclusion criteria; the remaining articles were read in full and 4 were selected to be part of the integrative literature review. Conclusion Despite the scarce literature and little information on methods for evaluating hypopharyngeal mucositis, the articles point out that, regardless of the radiation dose, radiotherapy in the cervical region causes hypopharyngeal mucositis. Hypopharyngeal mucositis causes a great impact on swallowing, resulting in the need to use an alternative feeding route. In addition to the lack of information regarding the assessment and grading of hypopharyngeal mucositis, the studies do not discussitsdirect treatment or prevention.

Resumen En la terapia con oxígeno hiperbárico (HBO) se utiliza oxígeno al 100% de concentración en una cámara presurizada con presiones supraatmosféricas, que corresponden de 2 a 3 atmósferas. Los mecanismos por los cuales funciona esta terapia se relacionan con propiedades físicas de los gases y su comportamiento fisiológico en el organismo, lo que lleva finalmente a la hiperoxia, evento fisiológico que permite la obtención de diversos efectos beneficiosos. La evidencia en medicina ha demostrado su utilidad mayormente en la enfermedad por descompresión, infecciones cutáneas graves e intoxicación por monóxido de carbono. En el ámbito de la otorrinolaringología ha probado ser útil en algunas enfermedades como la hipoacusia súbita idiopática, tanto como terapia única como asociada al uso de corticosteroides, como en la osteomielitis refractaria del oído externo, la que en conjunto con antibioticoterapia y manejo quirúrgico presenta un evidente aumento en la tasa de mejoría. Cabe mencionar que la terapia con HBO ha demostrado también beneficios en los tratamientos y complicaciones posteriores a la radiación en pacientes con cáncer de cabeza y cuello. Es importante mencionar que la terapia con HBO no está exenta de riesgos y requiere que los pacientes cumplan con características específicas para su utilización, por lo que su indicación debe ser juiciosa y en casos seleccionados.
Abstract In hyperbaric oxygen therapy, 100% pure oxygen is used in a pressurized chamber with super atmospheric pressures which correspond to 2-3 atmospheres. The mechanism by which this treatment works is related to the physical properties of gases and their physiological behavior in the body, which leads to hyperoxia, the physiological event which allows for diverse beneficial health effects. The evidence in medicine has proven its utility mainly in decompression sickness, severe skin infections and carbon monoxide poisoning. In the otolaryngology field it has been proven useful in diseases like idiopathic sudden sensorineural hearing loss, both as the only treatment and as a concurrent treatment along with corticosteroids, in malignant otitis externa which in conjunction with antibiotic treatment and a surgical approach presents a clear increase in improvement rates. It must be mentioned that hyperbaric chamber treatment has also shown benefits in radiation treatment and post radiation complications in head and neck cancer patients. It is important to note that hyperbaric oxygen therapy is not without risks and patients must meet specific criteria for it to be applied, therefore it must be indicated using careful judgement and only in necessary cases.

ABSTRACT BACKGROUND: Clinical assessment of head and neck cancers is highly challenging owing to the complexity of regional anatomy and wide range of lesions. The diagnostic evaluation includes detailed physical examination, biopsy and imaging modalities for disease extent and staging. Appropriate imaging is done to enable determination of precise tumor extent and involvement of lymph nodes, and detection of distant metastases and second primary tumors. OBJECTIVE: To evaluate the initial staging discrepancy between conventional contrasted computed tomography (CT) and 18F-fluorodeoxy-D-glucose positron emission tomography/computed tomography (18F-FDG PET/CT) and its impact on management plans for head and neck malignancies. DESIGN AND SETTING: Prospective cross-sectional study in two tertiary-level hospitals. METHODS: This study included 30 patients with primary head and neck malignant tumors who underwent contrasted computed tomography and whole-body 18F-FDG PET/CT assessments. The staging and treatment plans were compared with the incremental information obtained after 18F-FDG PET/CT. RESULTS: 18F-FDG PET/CT was found to raise the stage in 33.3% of the cases and the treatment intent was altered in 43.3% of them, while there was no management change in the remaining 56.7%. 18F-FDG PET/CT had higher sensitivity (96% versus 89.2%) and accuracy (93% versus 86.7%) than conventional contrast-enhanced computed tomography. CONCLUSION: Our study demonstrated that 18F-FDG PET/CT had higher sensitivity and accuracy for detecting head and neck malignancy, in comparison with conventional contrast-enhanced computed tomography. 18F-FDG PET/CT improved the initial staging and substantially impacted the management strategy for head and neck malignancies.

Resumen El cáncer de cabeza y cuello es una enfermedad infrecuente, con un manejo tanto médico como quirúrgico complejo. La regionalización o centralización de la atención, definida como la concentración de pacientes con enfermedades complejas, en instituciones que presenten equipos multidisciplinarios con mayor experiencia y altamente funcionales, puede ser una alternativa viable para lograr mejores resultados oncológicos. Actual-mente existe evidencia que avala esta estrategia, dando cuenta de mejores resultados oncológicos en centros con un mayor volumen; que tengan una mayor adherencia a guías clínicas basadas en la evidencia y a indicadores de calidad; y que presenten un equipo multidisciplinario a cargo de la toma de decisiones en estos pacientes. La población de Ontario, Canadá, se enmarca como uno de los ejemplos de esta estrategia, consiguiendo mejorar sus resultados manteniendo un alto nivel de calidad en su manejo. El objetivo del presente artículo de revisión es sistematizar el conocimiento actual en relación con la centralización de la atención en oncología de cabeza y cuello y sus consecuencias en la práctica de la otorrinolaringología-cirugía de cabeza y cuello.
Abstract Head and neck cancer is an infrequent disease, with complex medical and surgical management. The regionalization of care, defined as the concentration of patients with complex diseases, in institutions that present highly experienced and highly functional multidiscipli-nary teams, may be an efficient alternative to achieve better oncological outcomes. Currently, there is evidence that supports this strategy, accounting for better oncological outcomes in institutions with higher volume; that have greater compliance to evidence-based guidelines and quality indicators; and that present a multidisciplinary team in charge of the decision-making process in these patients. The population of Ontario, Canada, is framed as one of the examples of this strategy, managing to improve its results while maintaining a high level of quality in its management. The aim of this review paper is to systematize the current knowledge regarding head and neck regionalization of cancer care and its impact in the practice of otolaryngology-head and neck surgery.

Objective: To explore the clinical characteristics, treatment methods and outcomes of extramedullary plasmacytoma of the head and neck. Methods: A retrospective analysis was conducted on 10 cases with extramedullary plasmacytoma of the head and neck who were admitted to Henan Tumor Hospital from January 2005 to January 2020. Among the 10 patients, 6 were male and 4 were female. The average age at diagnosis was 56.3 years old (34-74 years old). Among them, 3 cases were located in the nasal cavity, 2 cases in the nasopharynx, 1 case in the sinuses, 2 cases in the larynx, 1 case in the oropharynx, and 1 case in the cervical lymph nodes. Treatments were administered according to tumor size and resection extent. Complete surgical excision (negative margins) was preferred, followed by adjuvant radiotherapy or radiotherapy alone. The clinical characteristics, diagnosis, treatment and prognosis of EMP were analyzed. Results: The patients' symptoms were not specific, frequently with local obstruction symptom and localized masses. All patients were confirmed pathologically as suffering from monoclonal plasmacytoma, with negative bone marrow biopsy and negative skeletal survey. Five patients received surgery, 3 received radiotherapy, and 2 received surgery with additional radiation. The follow-up time was 16-125 months, with a median of 92 months. Two patients developed into multiple myeloma. One patient who received radiotherapy after surgery relapsed after 7 years of follow-up and again received surgical treatment, with no evidence of second recurrence. The remaining patients had no recurrence or progression. Conclusion: Extramedullary plasmacytoma of the head and neck has a good prognosis. Surgical treatment can be considered for completely resectable lesions.

The heterogeneity of exhausted T cells (Tex) is a critical determinant of immune checkpoint blockade therapy efficacy. However, few studies have explored exhausted T cell subpopulations in human cancers. In the present study, we examined samples from two cohorts of 175 patients with head and neck squamous cell cancer (HNSCC) by multiplex immunohistochemistry (mIHC) to investigate two subsets of Tex, CD8+PD1+TCF1+ progenitor exhausted T cells (TCF1+Texprog) and CD8+PD1+TCF1- terminally exhausted T cells (TCF1-Texterm). Moreover, fresh tumor samples from 34 patients with HNSCC were examined by flow cytometry and immunohistochemistry to further investigate their properties and cytotoxic capabilities and their correlation with regulatory T cells (Tregs) in the tumor immune microenvironment (TIME). mIHC and flow cytometry analysis showed that TCF1-Texterm represented a greater proportion of CD8+PD1+Tex than TCF1+Texprog in most patients. TCF1+Texprog produced abundant TNFα, while TCF1-Texterm expressed higher levels of CD103, TIM-3, CTLA-4, and TIGIT. TCF1-Texterm exhibited a polyfunctional TNFα+GZMB+IFNγ+ phenotype; and were associated with better overall survival and recurrence-free survival. The results also indicated that larger proportions of TCF1-Texterm were accompanied by an increase in the proportion of Tregs. Therefore, it was concluded that TCF1-Texterm was the major CD8+PD1+Tex subset in the HNSCC TIME and that these cells favor patient survival. A high proportion of TCF1-Texterm was associated with greater Treg abundance.

A sobrevivência de pacientes com câncer de cabeça e pescoço vêm melhorando, entretanto, algumas deformidades podem ocorrer devido dos tratamentos cirúrgicos que geram mutilações bucomaxilofaciais como perda de dentes, estruturas do palato, língua ou assoalho, resultando em alterações na fonética, mastigação e deglutição. Nesses casos há a necessidade que seja realizado uma reabilitação protética buscando torná-los indivíduos com menos problemas sociais, psicológicos e físicos, visto que mais procedimentos cirúrgicos estão contra indicados para solucionar os efeitos colaterais gerados pelo tratamento das neoplasias. Esse tipo de reabilitação protética com prótese ou placa obturadora possibilita benefícios na fonética, facilita a convivência social e atividades nutricionais como alimentação e deglutição, permitindo ao paciente uma vida com menos constrangimentos. Este trabalho tem como objetivo relatar dois casos clínicos onde os pacientes foram submetidos a reabilitação com placa obturadora palatina feitos após cirurgias oncológicas. Os pacientes de gêneros diferentes e com comunicações buco-nasal similares receberam o mesmo planejamento reabilitador que foram confeccionadas a partir de um molde que foi enviado ao laboratório. Após a instalação foi possível verificar que houve sucesso no tratamento, notando uma melhora imediata comprovando a eficácia do método reabilitador(AU)
This paper relates two clinical cases where patients were recovered with a palatal splint made after oncological surgeries. Survival of patients and necks can occur, however, some deformities can occur during oral and maxillofacial treatment, such as the appearance of teeth, palate structures, mutilations or posterior jaws, leading to changes in aesthetics, surgery and swallowing. If the need to perform a prosthetic rehabilitation is necessary so that the results are seen with less problems, psychological and physical, that more procedures are performed so that the effects of neoplasms are contraindicated by the treatment. This type of prosthetic rehabilitation with prosthesis or obturator plate provides benefits in phonetics, facilitates social coexistence and nutritional activities such as eating and swallowing, allowing the patient a life with less constraints. Patients of different genders and with similar oral and nasal communications received the same rehabilitation plan that were made from a mold that was sent to the laboratory. After installation, it was possible to verify that the treatment was successful, noting an immediate improvement, proving the effectiveness of the rehabilitation method(AU)

Abstract Introduction: Head and neck squamous cell carcinoma is the seventh most common malignant tumor. The advances in treatment have improved the global survival rates in the past years, although the prognosis is still grave. Objective: The aim of the present study is to evaluate the correlation between positron emission computed tomography and computed tomography at the time of staging a previously untreated head and neck squamous cell carcinoma, and to determine which of the two imaging techniques gives us more information at the time of initial diagnosis. Methods: Data from all patients diagnosed in our hospital of head and neck squamous cell carcinoma by a biopsy of any location or unknown primary tumor was collected, between January 2012 and July 2017. In all cases, computed tomography and positron emission computed tomography were performed with a maximum of 30 days difference between them and patients had not received any prior treatment to staging. The stage given to each case was compared based solely on the physical examination, only on the computed tomography/positron emission computed tomography, with respect to the stage given by the tumor board, observing the concordance obtained through Cramer's V statistical test. Results: We performed a comparative analysis obtaining a correlation of 0.729 between the stage given by the tumor board and the one assigned based on the physical examination without imaging techniques. When only using computed tomography as an imaging method, the correlation was 0.848, whereas with only the use of positron emission computed tomography it was estimated at 0.957. When comparing the statistical association between staging using exclusively one of the two imaging techniques, correlation was 0.855. Conclusion: Positron emission computed tomography is useful for the diagnosis of head and neck squamous cell carcinoma, improving the patient's staging especially when detecting cervical and distant metastases. Therefore, we consider that the use of positron emission computed tomography for the staging of patients with head and neck squamous cell carcinoma is a diagnostic test to be considered.
Resumo Introdução: O carcinoma espinocelular de cabeça e pescoço é o sétimo tumor maligno mais comum. Os avanços no tratamento melhoraram as taxas de sobrevida global nos últimos anos, embora o prognóstico ainda seja grave. Objetivo: Avaliar a correlação entre a tomografia computadorizada por emissão de pósitrons e a tomografia computadorizada no estadiamento de carcinomas espinocelulares da cabeça e pescoço não tratados previamente e verificar qual das duas técnicas de imagem nos fornece mais informações no momento do diagnóstico inicial. Método: Os dados de todos os pacientes diagnosticados em nosso hospital com carcinoma espinocelular de cabeça e pescoço por biópsia de qualquer região ou adenopatias de origem desconhecida foram colhidos no período entre janeiro de 2012 e julho de 2017. Em todos os casos, uma tomografia computadorizada e uma tomografia computadorizada por emissão de pósitrons foram realizadas com um máximo de 30 dias de diferença entre elas. Nenhum paciente deveria ter recebido tratamento antes do estadiamento. O estadiamento atribuído a cada caso foi comparado com base apenas no exame físico, pela tomografia computadorizada ou apenas pela tomografia computadorizada por emissão de pósitrons, com relação ao estadiamento concedido pela margem tumoral, observou-se a concordância obtida pelo teste estatístico de V de Cramer. Resultado: Realizamos a análise comparativa obtendo uma correlação de 0,729 entre o estadio concedido pela margem tumoral e aquele atribuído com base no exame físico sem técnicas de imagem. Usando apenas a tomografia computadorizada como método de imagem, a correlação foi de 0,848, enquanto que a correlação com a tomografia computadorizada por emissão de pósitrons foi estimada em 0,957. Ao comparar a associação estatística entre o estadiamento usando exclusivamente uma das duas técnicas de imagem, foi de 0,855. Conclusão: Tomografia computadorizada por emissão de pósitrons é útil para o diagnóstico de carcinoma espinocelular de cabeça e pescoço, melhora o estadiamento, especialmente na detecção de metástases cervicais e à distância. Portanto, concluimos que seu uso para o estadiamento de pacientes com carcinoma espinocelular de cabeça e pescoço é um exame diagnóstico a ser considerado.

Abstract Introduction: Even with improved treatment outcomes with multimodality approaches, the question of what is the best initial treatment for locally advanced head and neck cancer still remains unanswered. Objective: To review the overall survival of a large cohort of head and neck cancer, patients with locally advanced head and neck cancer treated in a single institution. Material and methods: We studied a cohort of patients with locally advanced head and neck cancer treated in our institution in the last fifteen years. To gather a large sample of patients with adequate follow-up time, a cross-check between ours and Fundação Oncocentro de São Paulo databases were done. We included patients with head and neck cancer, clinical or pathological staging III or IV, treated with surgery followed by radiotherapy or surgery plus chemoradiation or radiotherapy alone or chemoradiation alone. Results: 796 patients with locally advanced head and neck cancer were included, 88% male, 44% age >60 years and 76% stage IV. The tumor location was the oral cavity (34%), oropharynx (27%), hypopharynx (17%) and larynx (17%). The treatment groups were chemoradiation alone (39.7%), surgery plus chemoradiation (26.3%), surgery followed by radiotherapy (18.5%) and radiotherapy alone (15.5%). Comparing the clinical variables between the treatment groups significant differences in age and clinical stage were observed. With a median follow up of 7.5 years (1-16 years), for the entire cohort, the overall survival at 5 and 10 years was 34.8% and 28%. The overall survival at 5 and 10 years was 16.7% and 12.2% for radiotherapy alone, 38.8% and 26.3% for surgery followed by radiotherapy, 28% and 16.6% for chemoradiation alone, and 37.3% and 23.2% for surgery plus chemoradiation. The staging IV (p = 0.03) and radiotherapy alone (p = 0.05), had a worst survival in multivariate analysis. Surgical groups vs. chemoradiation alone had no significant difference for overall survival. Conclusion: The present study is the largest cohort of locally advanced head and neck cancer of Brazilian patients to evaluate treatment outcomes. Although there were significant clinical differences between surgical and radiotherapy groups, surgery or chemoradiation alone as the initial treatment resulted in no significant difference in survival.
Resumo Introdução: Mesmo com a melhora dos desfechos de tratamento com abordagens multimodais, a dúvida sobre qual seria o melhor tratamento inicial para o câncer de cabeça e pescoço localmente avançado ainda permanece sem resposta. Objetivo: Mostrar a sobrevida global de uma grande coorte de pacientes com câncer de cabeça e pescoço localmente avançado tratados em uma única instituição. Material e método: Projetamos uma coorte de pacientes com câncer de cabeça e pescoço localmente avançado tratados em nossa instituição nos últimos 15 anos. Para reunir uma grande amostra de pacientes com tempo de seguimento adequado, foi realizada uma verificação cruzada entre nosso banco de dados e o banco de dados da fundação oncocentro de São Paulo. Foram incluídos os pacientes com câncer de cabeça e pescoço, estadiamento clínico ou histopatológico III ou IV, tratados com cirurgia seguida de radioterapia ou quimiorradioterapia ou radioterapia isolada ou quimiorradioterapia isolada. Resultados: Foram incluídos 796 pacientes com câncer de cabeça e pescoço localmente avançado, sendo 88% do sexo masculino, 44% com idade > 60 anos e 76% no estágio IV. O tumor estava localizado na cavidade oral (34%), orofaringe (27%), hipofaringe (17%) e laringe (17%). Os grupos de tratamento foram quimiorradioterapia (39,7%), cirurgia seguida de radioterapia ou quimiorradioterapia (26,3%), cirurgia seguida de radioterapia (18,5%) e radioterapia isolada (15,5%). Comparando as variáveis clínicas entre os grupos de tratamento, foram observadas diferenças significativas de idade e estágio clínico. Com uma mediana de tempo de seguimento de 7,5 anos (1-16 anos) para toda a coorte, a sobrevida global em 5 e 10 anos foi de 34,8% e 28%. A sobrevida global em 5 e 10 anos foi de 16,7% e 12,2% para radioterapia isolada, 38,8% e 26,3% para cirurgia seguida de radioterapia, 28% e 16,6% para quimiorradioterapia e 37,3% e 23,2% para cirurgia seguida de radioterapia ou quimiorradioterapia. O estágio IV (p = 0,03) e a radioterapia isolada (p = 0,05) apresentaram pior sobrevida na análise multivariada. Grupos cirúrgicos versus quimiorradioterapia não apresentaram diferença significante para a sobrevida global. Conclusão: O presente estudo é a maior coorte de câncer de cabeça e pescoço localmente avançado de pacientes brasileiros para avaliação dos desfechos do tratamento. Embora houvesse diferenças clínicas significativas entre os grupos cirúrgico e radioterápico, a cirurgia ou a quimiorradioterapia, como tratamento inicial, não apresentaram diferenças significantes em relação à sobrevida.

Head and neck squamous cell carcinoma (HNSCC), an aggressive malignancy, is characterized by high morbidity and low survival rates with limited therapeutic options outside of regional surgery, conventional cytotoxic chemotherapy, and irradiation. Increasing studies have supported the synergistic role of the tumor microenvironment (TME) in cancer advancement. The immune system, in particular, plays a key role in surveillance against the initiation, development, and progression of HNSCC. The understanding of how neoplastic cells evolve and evade the immune system whether through self-immunogenicity manipulation, or expression of immunosuppressive mediators, provides the foundation for the development of advanced therapies. Furthermore, the crosstalk between cancer cells and the host immune system have a detrimental effect on the TME promoting angiogenesis, proliferation, and metastasis. This review provides a recent insight into the role of the key inflammatory cells infiltrating the TME, with a focus on reviewing immunological principles related to HNSCC, as cancer immunosurveillance and immune escape, including a brief overview of current immunotherapeutic strategies and ongoing clinical trials.

Abstract Objective: To analyze self-concept adaptation and role function models in patients with oral cavity cancer. Methods: This is a qualitative study conducted with patients at a cancer reference hospital in Fortaleza, CE, Brazil. The interview was used as a data collection technique, using a semi-structured instrument, based on Callista Roy's theoretical framework. Data verification occurred based on thematic content analysis. Results: Two thematic categories emerged: Feelings involved in the daily life with the disease and Loss of social and family roles in the face of head and neck cancer. Slope in self-esteem, adaptive responses in self-physical, negative feelings in self-personal, positive adaptation in self-personal, positive adaptation, mediated by belief and religiosity were revealed in the category of feelings involved. Concerning loss of social and family roles, changes in roles were identified in the relationship with the family and society, due to the work situation, and the distance between the family and the need to continue radiotherapy cycles. Conclusion: It was found that effective responses in the self-concept model are found in the possibility of clarifying the focus that should be attributed to meeting this condition on screen as a way of promoting adaptation to the new condition of life.

Resumen El cáncer epidermoide es el más frecuente en cabeza y cuello y sus primeras descripciones datan de la época faraónica. Ha impactado en la humanidad al afectar la productividad laboral, científica y cultural y, en ocasiones, ha influido en el derrotero de la historia. El cáncer de cabeza y cuello es más frecuente en países e individuos depauperados económicamente, sin embargo, puede afectar cualquier estrato socioeconómico; lo han padecido personajes conocidos, famosos, económicamente poderosos, intelectuales y artistas. El tratamiento del cáncer de cabeza y cuello ha sido motivo de controversia desde su descripción inicial hasta la actualidad. En la decisión terapéutica ha influido no solo el estadio del cáncer sino el entorno del paciente; en ocasiones, en un afán de disminuir la morbilidad derivada de los diversos tratamientos oncológicos, se han tomado decisiones erróneas que han implicado la pérdida de la vida del enfermo. Infortunadamente, en la actualidad seguimos viendo estas conductas. Se presenta una síntesis de casos de connotados personajes que presentaron este cáncer y se describe el impacto que ello implicó en la sociedad de ese momento.
Abstract Squamous cell carcinoma is the most common head and neck malignancy, and its first descriptions date from the pharaonic era. It has impacted humanity by affecting labor, scientific and cultural productivity and, sometimes, it has influenced the course of history. Head and neck cancer is common in economically impoverished countries and individuals; however, it can affect any socioeconomic stratum; it has been suffered by known, famous, economically powerful celebrities, intellectuals and artists. Head and neck cancer treatment has been controversial since its initial description up to the present day. Therapeutic decisions have been influenced not only by the stage but by the patient's environment and, sometimes, in an effort to reduce the morbidity resulting from the various oncological treatments, erroneous decisions have been made that have implied the loss of the patient's life; unfortunately, currently we continue to see these behaviors. A synthesis of cases of renowned celebrities that suffered from this cancer is presented, and the impact this implied in the society of their times is described.

Resumo Este artigo objetiva apresentar o uso da triangulação na pesquisa qualitativa como estratégia para atingir os objetivos propostos, garantir credibilidade, confiabilidade e maior rigor científico em sua realização. Nesse sentido, a triangulação - por não se restringir à utilização de apenas um método, teoria, fonte de dados ou investigador no processo de análise de um mesmo fenômeno - possibilita a apreensão de uma dada realidade sob diversos ângulos, possibilitando o confrontamento de informações, de maneira a minimizar vieses resultantes de uma única perspectiva de análise. Com o intuito de evidenciar as possibilidades do uso de tal desenho metodológico, utilizou-se como exemplo um estudo qualitativo sobre vivências de cuidadores de pacientes com neoplasia de cabeça e pescoço, desenvolvido por meio de triangulação múltipla, a saber: triangulação metodológica (intramétodo), de dados, de investigador e ambiental. Ao se demonstrar um estudo estruturado, em forma de triangulação, tem-se como finalidade orientar pesquisadores interessados em realizar estudos qualitativos com um maior aprofundamento e rigor metodológico em pesquisa qualitativa.
Abstract This paper aims to present the use of triangulation in qualitative research as a strategy to achieve the proposed objectives, to ensure credibility, reliability, and greater scientific accuracy in its achievement. In this sense, triangulation - since it is not restricted to the use of only one method, theory, data source or researcher in the process of analyzing an event - allows the apprehension of a given reality from several angles, enabling information confrontation, in order to minimize bias resulting from a single analytical perspective. Thus, aiming at evidencing the possibilities of using such a methodological design, we used as an example a qualitative study about experiences of caregivers for patients with head and neck neoplasms, developed through multiple triangulation, namely: methodological (intra-method), data, researcher and environmental triangulation. When demonstrating a structured study in the form of triangulation, one aims to guide researchers interested in conducting qualitative studies with greater depth and methodological rigor in qualitative research.

Introdução: O câncer de cabeça e pescoço aumentou significativamente na última década. Objetivo: Determinar o perfil epidemiológico dos pacientes com câncer de cabeça e pescoço atendidos em um Centro Oncológico de referência no Sul do Brasil no período de janeiro de 2013 a dezembro de 2018. Método: Estudo de caráter descritivo e retrospectivo realizado no Centro de Pesquisas Oncológicas (Cepon). Resultados: Foram obtidos dados preliminares de 133 pacientes. O gênero masculino foi o mais prevalente (65,4%), com média de idade acima dos 50 anos, baixa escolaridade (40%), baixa renda (77,3%), sendo sua grande maioria tabagistas (72%) e etilistas (58,1%). A região de cavidade oral (26,3%) foi o sítio mais prevalente, a cirurgia mais realizada foi a tireoidectomia total (19,4%) e o estadiamento mais observado foi T2 (30,8%) N2 (41,1%). Foram encontradas complicações pós-radioterapia como a radiodermite (82,7%) e, pós-quimioterapia, náuseas (81%). As fibroses cicatriciais foram mais frequentes após a cirurgia (18,2%), sendo avaliadas no pós-operatório tardio. Conclusão: Caracterizar o perfil dos pacientes com câncer de cabeça e pescoço permite conhecer os diversos acometimentos advindos do tratamento e possibilita, dessa maneira, maior qualidade e direcionamento das ações de reabilitação.
Introduction: Head and neck cancer has increased significantly in the last decade. Objective: To determine the epidemiological profile in patients with head and neck cancer treated at an oncological referral center in Brazil Southern region from january 2013 to december 2018. Method: Descriptive and retrospective study carried out at CEPON (Oncology Research Center). Results: Preliminary data were obtained from 133 patients. Male gender was the most prevalent (65.4%), with mean age above 50 years, low education (40%), low income (77.3%), many of them were smokers (72%) and alcoholics (58.1%). The oral cavity region (26.3%) was the most prevalent site, the most performed surgery was total thyroidectomy (19.4%) and the most observed staging was T2 (30.8%) and N2 (41.1%). Post-radiotherapy and post-chemotherapy complications as radiodermatitis (82.7%) and nausea (81%), respectively, were found. Scarring fibrosis was more frequent after surgery (18.2%) and were evaluated in the late postoperative period. Conclusion: Characterizing the profile of patients with head and neck cancer allows to know the several affections resulting from the treatment to ensure better quality and focus of rehabilitation actions.

La mucositis es una respuesta inflamatoria del epitelio de la mucosa a los efectos citotóxicos de la quimioterapia y la radioterapia, que causan dolor y ulceración oral severa. En los estudios de los últimos años se ha propuesto el uso de la miel en el manejo de la mucositis oral inducida por quimioterapia y radioterapia en pacientes pediátricos. La miel reduce la severidad y duración de la mucositis, reduce el dolor y es un producto agradable a los niños. Por tanto, podría ser un producto eficaz tanto en la profilaxis como en el tratamiento de la mucositis oral. Sin embargo, la pequeña cantidad de investigaciones realizadas en humanos no es suficiente para establecer recomendaciones generalizadas. Por ello, se debe aumentar las investigaciones en este campo. Con ello se podrá examinar la eficacia y posibles complicaciones a corto y largo plazo, explorar su posible efecto sinérgico con otras terapias, analizar su rentabilidad económica y el tipo de miel más adecuado. De esta forma, los profesionales sanitarios podrán ofrecer a los pacientes pediátricos los mejores cuidados basados en las últimas evidencias científicas demostradas.
Mucositis is an inflammatory response of the mucosal epithelium to the cytotoxic effects of chemotherapy and radiation therapy, causing pain and severe oral ulceration. In the studies of recent years, the use of honey has been proposed in the management of oral mucositis induced by chemotherapy and radiotherapy in pediatric patients. Honey reduces the severity and duration of mucositis, reduces pain and is a child-friendly product. Therefore, it could be an effective product both in the prophylaxis and in the treatment of oral mucositis. However, the small amount of human research is not enough to establish widespread recommendations. Therefore, research in this field should be increased. With this, it will be possible to examine the efficacy and possible complications in the short and long term, explore its possible synergistic effect with other therapies, analyze its economic profitability and the most appropriate type of honey. In this way, healthcare professionals will be able to offer pediatric patients the best care based on the latest scientific evidence.
