ABSTRACT

O papilomavírus humano (HPV) é a doença sexualmente transmissível mais comum em todo o mundo, mais de 150 tipos de HPV já foram identificados, sendo que 25 tipos estão associados a lesões em cavidade oral e genital. O diagnóstico e tratamento precoce das lesões por HPV são importantes para um melhor prognóstico do paciente. O presente estudo objetiva relatar o caso clínico de uma paciente com papiloma de células escamosas. Trata-se portanto de um tumor benigno, onde o tratamento consiste na remoção completa da lesão com a devida margem de segurança. Recidivas são incomuns, contudo o paciente deve manter acompanhamento odontológico periódico, e encaminhado para acompanhamento médico(AU)


Human papillomavirus (HPV) is the most common sexually transmitted disease worldwide, with more than 150 types of HPV identified. Among types, 25 of which are associated with lesions in the oral and genital cavity. Early diagnosis and treatment of HPV lesions are important for a better patient prognosis. The study aim to report the clinical case of a patient with squamous cell papilloma. It is, therefore, a benign tumor, where treatment consists of complete removal of the lesion with the necessary safety margin. Relapses are uncommon, but the patient must maintain periodic dental care and be referred for medical follow-up(AU)

ABSTRACT

ABSTRACT Objective: To compare enhancement patterns of typical adrenal adenomas, lipid-poor adenomas, and non-adenomas on magnetic resonance imaging (MRI). Materials and Methods: Evaluation of adrenal nodules larger than 1.0 cm, with at least 2-year follow-up, evaluated on MRI in January 2007 and December 2016. Two different protocols were included - upper abdomen MRI (delayed phase after 3 minutes) and abdomen and pelvis MRI (delayed phase after 7 minutes) - and nodules were divided in typical adenomas (characterized on out-of-phase MRI sequence), lipid-poor adenomas (based on follow-up imaging stability) and non-adenomas (based on pathological finding or follow-up imaging). T2-weighted and enhancement features were analyzed (absolute and relative washout and enhancement curve pattern), similarly to classic computed tomography equations. Results: Final cohort was composed of 123 nodules in 116 patients (mean diameter of 1.8 cm and mean follow up time of 4 years and 3 months). Of them, 98 (79%) nodules had features of typical adenomas by quantitative chemical shift imaging, and demonstrated type 3 curve pattern in 77%, mean absolute and relative washout of 29% and 16%, respectively. Size, oncologic history and T2-weighted features showed statistically significant differences among groups. Also, a threshold greater than 11.75% for absolute washout on MRI achieved sensitivity of 71.4% and specificity of 70.0%, in differentiating typical adenomas from non-adenomas. Conclusion: Calculating absolute washout of adrenal nodules on MRI may help identifying proportion of non-adenomas.

ABSTRACT

El carcinoma oral de células escamosas representa un problema en la salud pública a nivel mundial. Siendo la neoplasia maligna más frecuente en la cavidad oral y uno de los diez cánceres más comunes en todo el mundo. El carcinoma verrucoso es una variante del carcinoma oral de células escamosas que presenta un alto grado de invasión local y baja posibilidad de extenderse. Además, representa del 2 al 12% de todos los carcinomas orales, con una tasa de supervivencia de 5 años. El presente artículo reporta el caso de un paciente masculino de 79 años, después de realizados los exámenes extra e intraoral, así como los complementarios, se observa un aumento de volumen en la porción anterior de la mandíbula, crateriforme irregular, doloroso a la palpación. Se diagnosticó carcinoma verrucoso involucrando a los órganos dentarios 3.3-4.3 y la mucosa circundante. El tratamiento consistió en la remoción quirúrgica completa, sin alteración o daño a las zonas circundantes, con seguimiento postoperatorio. El conocimiento de este tipo de patología puede orientar al odontólogo a la sospecha de diferentes lesiones cancerígenas, lo que permitirá prevenir complicaciones y así brindar la mejor opción de tratamiento a los pacientes afectados.


Oral squamous cell carcinoma represents a worldwide public health problem. Being the most common malignant neoplasm in the oral cavity and one of the ten most common cancers worldwide. Verrucous carcinoma is a variant of oral squamous cell carcinoma that has a high degree of local invasion and low possibility of spreading. In addition, it represents 2 to 12% of all oral carcinomas, with a 5-year survival rate. This article reports the case of a 79-year-old male patient, after performing the extra and intraoral exams, as well as the complementary ones, an increase in volume is observed in the anterior portion of the mandible, irregular crateriform, painful on palpation. Verrucous carcinoma was diagnosed involving teeth 3.3-4.3 and the surrounding mucosa in the oral cavity. The treatment consisted of complete surgical removal, without alteration or damage to the surrounding areas, with postoperative follow-up. Knowledge of this type of pathology can guide the dentist to the suspicion of different cancerous lesions, which will prevent complications and thus provide the best treatment option for affected patients.

ABSTRACT

Abstract Introduction All patients with a new head and neck squamous cell carcinoma (HNSCC) undergo diagnostic panendoscopy as part of the screening for synchronous second primary tumors. It includes a pharyngolaryngoscopy (PLS), a tracheobronchoscopy and esophagoscopy, and a stomatoscopy. Rigid techniques are risky, with long learning curves. Objective We propose a precise description of the panendoscopy protocol. We include an optimization of the PLS technique that completes the flexible esophagoscopy when rigid esophagoscopy isn't performed. Methods The present retrospective observational study includes 122 consecutive patients with a new primary HNSCC who underwent traditional panendoscopy and the new PLS technique between January 2014 and December 2016. A two-step procedure using a Macintosh laryngoscope and a 30° telescope first exposes panoramically the larynx, the upper trachea, and the oropharynx; then, in a second step, the hypopharynx is exposed down to the upper esophageal sphincter. Broncho-esophagoscopy is performed with a rigid and flexible scope. Results In total, 6 (5%) patients presented synchronous tumors (3 in the esophagus, 2 in the oral cavity, and 1 in the larynx 1). Rigid endoscopy was complicated by 2 (1,6%) dental lesions, and had to be completed with a flexible scope in 38 (33%) cases for exposition reasons. The two-step PLS offered a wide-angle view of the larynx, upper trachea, and oroand hypopharynx down to the sphincter of the upper esophagus. The procedure was easy, reliable, safe, repeatable, and effectively completed the flexible endoscopies. Conclusion Rigid esophagoscopy remains a difficult procedure. Two-step PLS combined with flexible broncho-esophagoscopy offers good optical control.

ABSTRACT

Introduction Mucoepidermoid carcinoma (MEC) is a tumor originated from the epitheliumof the glandular excretory ducts and has highly variable biological potential. It is the most prevalent cancer of the salivary glands. The present report aims to describe a case of nasal mucoepidermoid carcinoma that developed after adjuvant radiotherapy (RT) treatment of a recurrent pituitary macroadenoma. Case Report Male patient, 62 years old, presented with recurrent nasal epistaxis on the right, associated with intense pulsatile headache, visual analogical scale (VAS) 10/10, with improvement only with the use of opioids andmorphine. After undergoing oncological screening and study by imaging exams, the presence of an expansive seal lesion with suprasellar extension was seen, involving the medial wall of the cavernous segment of the right carotid artery and the anterior cerebral artery, as well as the presence of a new expansive lesion in the right nasal cavity, with ethmoid bone invasion superiorly and medial orbit wall invasion laterally, compressing the ipsilateral optic nerve canal. Discussion Sinonasal neoplasms represent a small portion of all malignancies of the upper aerodigestive tract, accounting for<5% of these neoplasms. The development of MEC involves risk factors such as occupational issues, history of trauma and surgery involving the nasal area, and radiation exposure, as in previous RT. Conclusion Mucoepidermoid carcinoma is an uncommon neoplasia and can be associated with RT treatment, as used in cases of recurrent pituitary macroadenoma. In general, surgical resection to obtain free margins of neoplastic tissue is the aimed treatment, seeking better prognosis.

O objetivo do trabalho foi demonstrar a viabilidade do retalho proposto para reconstrução da asa nasal após a retirada de tumores cutâneos. Métodos: Foram analisados 20 casos de retalho nasogeniano de pedículo inferior realizados com a mesma técnica cirúrgica no período entre 2008 e 2019 e acompanhados por um ano de pós-operatório. Resultados: Dos 20 casos estudados, 13 (65%) não apresentaram complicações, sendo as mais relatadas: cobertura parcial do defeito e desaparecimento parcial do sulco nasogeniano. Conclusão: O retalho nasogeniano de base inferior mostrou ser um retalho viável à reconstrução da asa nasal pela qualidade de pele, fácil execução e índices mínimos de complicações.


Introduction: The nasal alar has always been a major reconstructive diflculty, and in the search for a flap with skin characteristics similar to this one, we came across the inferiorly based nasolabial flap. The objective of this study was to demonstrate the viability of the proposed flap for reconstruction of the nasal alar after removal of skin tumors. Methods: This study analysed twenty cases of inferiorly based nasolabial flap performed with the same surgical technique in the period between 2008-2019 and followed up for one year of postoperative. Results: Of the 20 studied cases, 13 (65%) did not present complications, being the most described: partial defect coverage and partial disappearance of the nasolabial sulcus. Conclusion: The inferiorly based nasolabial flap proved to be a viable flap for nasal alar reconstruction due to the quality of the skin, easy execution, and minimal complication rates.

ABSTRACT

Abstract Introduction Sclerosing odontogenic carcinoma was a new addition to the list of head and neck tumors by World Health Organization in 2017. This lesion has scarcely been reported and a lack of pathognomonic markers for diagnosis exists. Objective The aim of the study was to summarize findings from the available literature to provide up-to-date information on sclerosing odontogenic carcinoma and to analyse clinical, radiological, and histopathological features to obtain information for and against as an odontogenic malignancy. Methods We conducted a comprehensive review of literature by searching Pubmed, EBSCO and Web of Science databases, according to PRISMA guidelines. All the cases reported as sclerosing odontogenic carcinoma in English were included. Data retrieved from the articles were gender, age, clinical features, site, relevant medical history, radiographical findings, histopathological findings, immunohistochemical findings, treatments provided and prognosis. Results Mean age at diagnosis of sclerosing odontogenic carcinoma was 54.4 years with a very slight female predilection. Sclerosing odontogenic carcinoma was commonly reported in the mandible as an expansile swelling which can be asymptomatic or associated with pain or paraesthesia. They appeared radiolucent with cortical resorption in radiograph evaluation. Histologically, sclerosing odontogenic carcinoma was composed of epithelioid cells in dense, fibrous, or sclerotic stroma with equivocal perineural invasion. Mild cellular atypia and inconspicuous mitotic activity were observed. There is no specific immunohistochemical marker for sclerosing odontogenic carcinoma. AE1/AE3, CK 5/6, CK 14, CK19, p63 and E-cadherin were the widely expressed markers for sclerosing odontogenic carcinoma. Surgical resection was the main treatment provided with no recurrence in most cases. No cases of metastasis were reported. Conclusion From the literature available, sclerosing odontogenic carcinoma is justifiable as a malignant tumor with no or unknown metastatic potential which can be adequately treated with surgical resection. However, there is insufficient evidence for histological grading or degree of malignancy of this tumor.


Resumo Introdução O carcinoma odontogênico esclerosante é a nova adição à lista de tumores de cabeça e pescoço da Organização Mundial da Saúde em 2017. Essa lesão é pouco relatada e não há marcadores patognomônicos para o diagnóstico. Objetivo Resumir os achados da literatura disponível para fornecer informações atualizadas sobre o carcinoma odontogênico esclerosante e analisar as características clínicas, radiológicas e histopatológicas a favor e contra sua classificação como uma lesão odontogênica maligna. Método Uma revisão abrangente da literatura foi feita nos bancos de dados Pubmed, Ebsco e Web of Science, de acordo com as diretrizes do Prisma. Todos os casos relatados em inglês como carcinoma odontogênico esclerosante foram incluídos. Os dados recuperados dos artigos foram sexo, idade, características clínicas, sítio do tumor, histórico médico relevante, achados radiográficos, achados histopatológicos, achados imuno-histoquímico, tratamentos instituídos e prognóstico. Resultados A média de idade ao diagnóstico de carcinoma odontogênico esclerosante foi de 54,4 anos, com uma predileção muito leve pelo sexo feminino. Tumores do tipo carcinoma odontogênico esclerosante foram comumente relatados na mandíbula como um edema expansivo, que pode ser assintomático ou associado a dor ou parestesia. Eles têm aparência radiolucente com reabsorção cortical na radiografia. Histologicamente, o carcinoma odontogênico esclerosante é composto por células epitelioides em estroma denso, fibroso ou esclerótico com invasão perineural ambígua. Atipia celular leve e atividade mitótica imperceptível foram observadas. Não há um marcador imuno-histoquímico específico para SOC. AE1/AE3, CK 5/6, CK 14, CK19, p63 e E-caderina foram os marcadores amplamente expressos para carcinoma odontogênico esclerosante. A ressecção foi o principal tratamento feito sem recorrência na maioria dos casos. Nenhum caso de metástase foi relatado. Conclusão De acordo com a literatura disponível, é justificável classificar o carcinoma odontogênico esclerosante como um tumor maligno com nenhum ou desconhecido potencial metastático, que pode ser tratado adequadamente com ressecção cirúrgica. Entretanto, não há evidências suficientes para a graduação histológica ou de malignidade desse tumor.

ABSTRACT

Abstract Jorge Lobo's disease (JLD) is a chronic, granulomatous fungal infection caused by the traumatic implantation of the fungus Lacazia loboi in the cutaneous and subcutaneous tissues, with the presence of isolated nodular and coalescent keloidal lesions. Malignant degeneration is rare. This case report describes a 64-year-old male patient with JLD for 30-years who showed a change in the aspect of a lesion in the left lower limb. Histopathological examination confirmed the progression to well-differentiated squamous cell carcinoma (SSC). JLD is highly prevalent in tropical and subtropical regions, requiring monitoring concerning the transformation into SSC in long-term lesions.

ABSTRACT

Abstract Basaloid follicular hamartoma is a benign, superficial malformation of hair follicles that can be mistaken both clinical and histopathologically for basal cell carcinoma. Basaloid follicular hamartoma has been linked to a mutation in the PTCH-1 gene, which is part of the same pathway involved in Gorlin-Goltz syndrome. Here we present a 9-year-old patient with an asymptomatic congenital lesion on the forehead, which increased in size over the years. Histopathology showed a basaloid follicular hamartoma associated with follicular mucinosis and inflammation. Gorlin-Goltz syndrome was ruled out by clinical examination.

ABSTRACT

Abstract Objective: To compare 68Ga-DOTA-DPhe1,Tyr3-octreotate (68Ga-DOTATATE) positron-emission tomography/computed tomography (PET/CT) findings with those of conventional 111In-octreotide scintigraphy in patients with neuroendocrine tumors (NETs). Materials and Methods: This was a single-center prospective study including 41 patients (25 males; mean age, 55.4 years) with biopsy-proven NETs who underwent whole-body 111In-octreotide scintigraphy and whole-body 68Ga-DOTATATE PET/CT. The patients had been referred for tumor staging (34.1%), tumor restaging (61.0%), or response evaluation (4.9%). Images were compared in a patient-by-patient analysis to identify additional lesions, and we attempted to determine the impact that discordant findings had on treatment planning. Results: Compared with 111In-octreotide scintigraphy, 68Ga-DOTATATE PET/CT revealed more lesions, the additional lesions typically being in the liver or bowel. Changes in management owing to the additional information provided by 68Ga-DOTATATE PET/CT occurred in five patients (12.2%), including intermodal changes in three (7.3%) and intramodal changes in two (4.9%). In addition, 68Ga-DOTATATE PET/CT yielded incidental findings unrelated to the primary NET in three patients (7.3%): Hürthle cell carcinoma of the thyroid, bowel non-Hodgkin lymphoma, and a suspicious breast lesion. Conclusion: We conclude that 68Ga-DOTATATE PET/CT is superior to conventional 111In-octreotide scintigraphy for the management of NETs because of its ability to determine the extent of the disease more accurately, which, in some cases, translates to changes in the treatment plan.


RESUMO Objetivo: Comparar os achados da PET/CT com 68Ga-DOTATATE em relação aos da cintilografia com 111In-octreotide em pacientes com tumores neuroendócrinos (TNEs). Materiais e Métodos: Estudo prospectivo unicêntrico incluindo 41 pacientes (25 homens; média de idade: 55,4 anos) com TNEs comprovados por biópsia submetidos a cintilografia de corpo inteiro com 111In-octreotide e PET/CT com 68Ga-DOTATATE. Os pacientes incluídos foram encaminhados para estadiamento do tumor (34,1%), reestadiamento (61,0%) ou avaliação da resposta (4,9%). As imagens foram comparadas para identificar lesões adicionais e o impacto dos achados discordantes no planejamento terapêutico. Resultados: Na comparação com a cintilografia com 111In-octreotide, a PET/CT com 68Ga-DOTATATE revelou mais lesões, mais frequentemente localizadas no fígado e intestino. Mudanças no tratamento devidas às informações adicionais reveladas pela PET/ CT ocorreram em 5/41 pacientes (12,2%), incluindo mudanças intermodalidade em três casos (7,3%) e intramodalidade em dois casos (4,9%). A PET/CT também identificou achados incidentais não relacionados ao TNE em 3/41 pacientes (7,3%), incluindo um carcinoma de células de Hürthle da tireoide, um linfoma não Hodgkin de intestino e uma lesão mamária suspeita. Conclusão: A PET/CT com 68Ga-DOTATATE é superior à cintilografia convencional com 111In-octreotide para o manejo de pacientes com TNEs, em virtude da sua capacidade de detectar a extensão da doença com mais precisão, o que se traduz, em alguns casos, em alterações terapêuticas.

ABSTRACT

Carcinoma basocelular (CBC) é o câncer de pele mais comum. Quando localizado na região nasal, a reconstrução do defeito resultante de sua exérese pode se tornar muito desafiadora para o cirurgião dermatológico. A técnica do retalho em caracol (RC) pode ser utilizada para defeitos, principalmente na parede lateral do nariz, mas também a utilizamos de maneira modificada para fechamento de lesão da asa nasal. Nos dois casos, os resultados foram satisfatórios, tanto pela cosmética quanto pela funcionalidade.


Basal cell carcinoma (BCC) is the most common skin cancer. When located in the nasal region, reconstructing the defect resulting from its exeresis can become very challenging for the dermatological surgeon. The snail flap (SF) technique can be used to correct defects, mainly on the nose's lateral wall, but we use it in a modified way to close the nasal wing injury. In both cases, the results were satisfactory, cosmetically and functionally.

ABSTRACT

ABSTRACT Cemiplimab is a novel programmed death-1 inhibitor recently approved for advanced cutaneous squamous cell carcinoma. Immune-related adverse events derived from cemiplimab are similar to other anti-PD-1 drugs, including gastrointestinal and cutaneous toxicities. Oral immune-related adverse events were not reported with cemiplimab in previous studies; thus this case report warns of the fact that the oral cavity may be a site of immune-related adverse events during programmed death-1 block therapy and that this can lead to significant limitations when not properly treated. The present report describes the case of a patient with locally advanced cutaneous squamous cell carcinoma metastatic to cervical lymph nodes who developed dysphagia due to large and painful oral ulcers after a single dose of cemiplimab. The patient also exhibited a sarcoid-like reaction in mediastinal lymph nodes. No immune-related adverse events were found in any other organs. The oral lesions showed significant improvement after topical and short-course systemic corticosteroids, and low-level laser therapy was also performed in the oral lesions. The patient achieved a near-complete response and treatment was discontinued. This article discusses in detail the clinical outcomes and oral toxicity management of cemiplimab therapy for cutaneous squamous cell carcinoma.

ABSTRACT

ABSTRACT Objective To understand the feasibility of FGFR3 tests in the Brazilian public health context, and to sample the mutational burden of this receptor in high-grade muscle invasive bladder cancer. Methods A total of 31 patients with high-grade muscle-invasive bladder cancer were included in the present study. Either transurethral resection of bladder tumor or radical cystectomy specimens were analyzed. Formalin-fixed paraffin-embedded tissue blocks were sectioned, hematoxylin and eosin stained, and histologic sections were reviewed. Total RNA was extracted using the RNeasy DSP formalin-fixed paraffin-embedded kit. Qualitative results were displayed in Rotor-Gene AssayManager software. Results Six patients were excluded. From the samples analyzed, four (16.7%) were considered inadequate and could not have their RNA extracted. Two patients presented FGFR3 mutations, accounting for 9.5% of material available for adequate analysis. The two mutations detected included a Y373C mutation in a male patient and a S249C mutation in a female patient. Conclusion FGFR3 mutations could be analyzed in 84% of our cohort and occurred in 9.5% of patients with high-grade muscle invasive bladder cancer in this Brazilian population. FGFR3 gene mutations are targets for therapeutic drugs in muscle-invasive bladder cancer. For this reason, know the frequency of these mutations can have a significant impact on public health policies and costs provisioning.

ABSTRACT

ABSTRACT Mammary analogue secretory carcinoma is a rare neoplasm usually confused with other neoplasms in the salivary glands region. It has great similarity with the breast carcinoma. We report a case of a patient who presented with gingival submucosal bleeding and lesion, with the initial histopathological examination revealing salivary gland neoplasm of low crane. Computed tomography revealed the lesion near the tooth 27, with extension to the floor of the left maxillary sinus and to the palate mucosa. Resection of the infra-structure was performed, with a diagnosis of breast cancer secretory carcinoma in the minor salivary gland.

ABSTRACT

Abstract Lower lip squamous cell carcinomas (LLSCC) could be associated with a previous history of potentially malignant oral diseases (PMOD), especially actinic cheilitis (AC), with high sun exposure being a well-described risk factor. Immune evasion mechanisms, such as the PD-1/PD-L1 (programmed cell death protein 1/programmed death-ligand 1) pathway has been gaining prominence since immunotherapy with immune checkpoint inhibitors showed a positive effect on the survival of patients with different types of neoplasms. Concomitant with the characterization of the tumor microenvironment, the expression of either or both PD-1 and PD-L1 molecules may estimate mutual relations of progression or regression of the carcinoma and prognostic values of the patient. Objective: Considering the importance of tumor microenvironment characterization, this study aims to determine the immunoexpression of PD-L1 and correlate with the frequency of CD4+ and CD8+ cells in AC and LLSCC lesions and with tumor-infiltrating lymphocytes (TILs) in LLSCC and its relationship with histopathological characteristics. Methodology: This sample includes 33 cases of AC and 17 cases of LLSCC. The cases were submitted to histopathological analysis and to CD4+, CD8+, and PD-L1+ cell determination by immunohistochemistry. Results: There was a significant difference among the frequencies of CD4+, CD8+, and PD-L1+ cells between AC and LSCC cases, higher in the last group. Moreover, histopathological and atypical changes in AC and LLSCC were correlated with the frequencies of PD-L1+, CD4+, and CD8+ cells. In AC, PD-L1+ cases had a low frequency of CD4+ cells, but on the other hand, PD-L1+ cases of LLSCC had a higher frequency of CD4+ and CD8+ cells. Conclusion: Therefore, the PD-L1 molecule may be a potential escape route for the immune response in oral lesions, but the mechanisms differ between AC and LLSCC. Future studies related to immune evasion and immunotherapy in oral lesions should consider the analysis of inflammatory infiltrate and TILs.

ABSTRACT

ABSTRACT: Objective: This study aimed to describe and analyze the temporal and spatial distribution of deaths due to hepatocellular carcinoma (HCC) associated with hepatitis B (HBV) and C viruses (HCV) in the state of São Paulo. Methods: This is an ecological study of HCC deaths associated with HBV and HCV in the state of São Paulo, from 2009 to 2017, with data from the Mortality Information System (SIM). The temporal trend was analyzed by linear regression with Prais-Winsten estimation. Deaths were described according to sociodemographic characteristics by means of absolute and relative frequencies and were spatially distributed according to the regional health department. Results: It is found that 26.3% of deaths due to HCC were associated with HBV or HCV. A higher proportion of deaths due to HCC associated with HCV was observed (22.2%) when compared to HBV (3.9%). The mortality rate due to HCC associated with HBV showed a downward trend, and the mortality rate due to HCC associated with HCV showed a steady trend. Deaths of males, white individuals, those who aged from 50 to 59 years, and those who had 8-11 years of schooling predominated. Spatial analysis revealed a heterogeneous distribution of deaths in the state of São Paulo. Conclusions: The downward trend in mortality rates due to HCC associated with HBV shows an important advance in the disease control. However, the mortality rate due to HCC associated with HCV has remained stable throughout the study period. The spatial distribution of deaths may contribute to raise hypotheses for deeper knowledge of these diseases in the regions.


RESUMO: Objetivos: Este estudo tem como objetivo descrever e analisar a distribuição temporal e espacial dos óbitos por carcinoma hepatocelular associados às hepatites virais B e C no estado de São Paulo. Métodos: Estudo ecológico dos óbitos por carcinoma hepatocelular associados a hepatites virais B e hepatites virais C no estado de São Paulo, de 2009 a 2017, com dados do Sistema de Informação sobre Mortalidade. A tendência temporal foi analisada por regressão linear, com método de Prais-Winsten. Os óbitos foram descritos segundo as características sociodemográficas, por meio de frequências absolutas e relativas, e foram espacialmente distribuídos segundo departamento regional de saúde. Resultados: Dos óbitos por carcinoma hepatocelular, 26,3% foram associados a hepatites virais B ou hepatites virais C. Observou-se maior proporção de óbitos por carcinoma hepatocelular associado a hepatites virais C (22,2%) quando comparada àquela associada a hepatites virais B (3,9%). A taxa de mortalidade por carcinoma hepatocelular associado a hepatites virais B apresentou tendência de queda, no entanto a taxa de mortalidade por carcinoma hepatocelular associado a hepatites virais C apresentou tendência estacionária. Predominaram óbitos de pacientes do sexo masculino, de cor branca, de 50-59 anos e com oito a 11 anos de estudo. A análise espacial revelou distribuição heterogênea dos óbitos no estado de São Paulo. Conclusão: A tendência de queda nas taxas de mortalidade por carcinoma hepatocelular associado a hepatites virais B revela um importante avanço no controle do agravo. Entretanto, a taxa de mortalidade por carcinoma hepatocelular associado a hepatites virais C vem-se mantendo estável ao longo do período estudado. A distribuição espacial dos óbitos pode contribuir para levantar hipóteses com vistas ao conhecimento mais aprofundado desses agravos nas regiões.

ABSTRACT

O carcinoma de células renais (CCR) é o sétimo tipo de câncer mais comum no ocidente e vêm apresentando um aumento em sua prevalência. A classificação histológica dos CCRs é a abordagem mais utilizada para determinar o subtipo da doença, bem como prognosticar o paciente. Cerca de 70-80% dos CCRs é do subtipo células claras (ccRCC), o qual representa o subtipo mais prevalente e agressivo da doença. A escolha do tratamento difere para cada paciente, sendo a ressecção cirúrgica a terapia mais efetiva nos casos de doença localizada. Apesar de ser um tratamento já estabelecido, estudos mostram uma certa heterogeneidade entre massas renais detectadas, onde cerca de 20% apresentam um perfil benigno, 60% são considerados tumores indolentes, sugerindo desta forma que, entender de forma mais detalhada este tumor pode auxiliar na escolha de um tratamento mais direcionado para o paciente. Sendo assim, o presente trabalho buscou selecionar genes potencialmente alterados em CCR com o intuito de customizar um painel multigênico capaz de identificar variantes somáticas, específicas do tumor, e avaliar as variantes específicas do tumor de forma personalizada em amostras de ctDNA (DNA tumoral circulante) extraídas de plasma e dos dois componentes da urina (sedimento e sobrenadante) coletados no momento da cirurgia (baseline). Neste contexto, dentro de nossa proposta, construímos um painel com 28 genes associados com CCR e sequenciamos 89 casos de tumores renais, juntamente com as amostras de leucócitos. Identificamos que dentre os tumores analisados, 59 apresentavam pelo menos uma variante somática, ou seja, o painel customizado apresentou uma sensibilidade para identificar variantes somáticas em 66% dos casos. Com relação aos 45 tumores classificados como ccRCC em 38 casos identificamos pelo menos uma marca tumoral, ou seja, nosso painel foi capaz de detectar variantes somáticas específicas do tumor em 84,4% desses casos. Um total de 105 variantes somáticas foram identificadas, e os genes mais frequentemente mutados nessa coorte de pacientes foram os genes VHL, PBRM1, BAP1, SETD2. Dos 59 casos em que identificamos variante somática, 44 casos foram avaliados as amostras baseline de plasma e 29 casos de urina (sobrenadante e sedimento), e encontramos pelo menos uma marca tumoral em um dos fluidos corpóreos em 11 pacientes, 6 em amostras de plasma e 6 amostras de urina. Através do desenvolvimento deste estudo, confirmamos que o subtipo ccRCC é o CCR mais bem caracterizado genomicamente e que é importante continuar a investigação genômica principalmente nos subtipos não ccRCC. Além disso o estudo demonstra a viabilidade de utilizar biópsia líquida ctDNA tanto no plasma quanto na urina para fins de diagnóstico e prognóstico.


Renal cell carcinoma (RCC) is the seventh most common type of cancer in the West and its prevalence is increasing. The histological classification of RCCs is the most used approach to determine the disease subtype as well as the patient's prognosis. About 70% of RCCs are of the clear cell Renal Cell Carcinoma subtype (ccRCC), which represents the most prevalent and aggressive subtype of the disease. The choice of treatment is different for each patient. Resection is one of the most effective therapies in cases of localized disease. Despite being an established treatment, studies show a certain heterogeneous profile studied. In this profile, up to 20% even present a benign treatment, helping the indolent, thus suggesting that understanding this tumor in detail can help to choose a more targeted treatment for the patient. Therefore, the present work aimed to select potentially altered genes in CCR in order to customize a multigene panel capable of identifying somatic, tumor-specific variants, and to evaluate the tumor-specific variants in a personalized way in ctDNA (circulating tumor DNA) samples extracted from plasma and from two components of urine (sediment and supernatant) collected at the time of surgery (baseline). In this context, within our proposal, we built a panel with 28 genes associated with CCR and sequenced 89 cases of renal tumors, together with leukocyte samples. We identified that among the analyzed tumors, 59 had at least one somatic variant, that is, the customized panel showed sensitivity to identify somatic variants in 66% of cases. Of the 45 classified as ccRCC in 38 cases we identified at least one tumor marker, that is, our panel was able to detect tumor-specific somatic variants in 84.4%. A total of 105 somatic variants were identified, and the genes most frequently mutated in this cohort of patients were the VHL, PBRM1, BAP1, SETD2 genes. Among 59 cases in which we identified somatic variant, 44 cases were evaluated in baseline plasma samples and 29 cases in urine (supernatant and sediment), and we found at least one tumor mark in one of the body fluids in 11 patients, 6 in plasma samples and 6 urine samples. Through the development of this study, we confirm that the ccRCC subtype is the best genomically characterized CCR and that it is important to continue genomic investigation, especially in the non-ccRCC subtypes. Furthermore, the study demonstrates the feasibility of using ctDNA liquid biopsy in both plasma and urine for diagnostic and prognostic purposes.

ABSTRACT

Introdução:O carcinoma de células escamosas de cavidade oral e orofaringe é uma neoplasia epitelial maligna comum, respondendo pela maioria dos casos de tumores de cabeça e pescoço. Ele está relacionado a hábitos comportamentais, como tabagismo e etilismo de longa duração, e à infecção pelo Papilomavírus humano. Objetivos:Esse estudo objetivou descrever o perfil epidemiológico dos pacientes diagnosticados com essa neoplasia na Liga Mossoroense de Estudos e Combate ao Câncer. Metodologia: Foi realizado um estudo observacional com delineamento transversal a partir de dados presentes nos prontuários clínicos e laudos anatomopatológicos e no Sistema de Informações sobre Mortalidade no período entre 2006 a 2018. Os dados foram analisados a partir do Software R, utilizandoo teste de Wilcoxon-Mann-Whitney para as análises inferenciais e o método de Kaplan-Meier para análise da sobrevida. Resultados:225 prontuários foram analisados, sendo 70,22% de homens, 65,33% na faixa etária entre 46-70 anos e cor branca (51,57%). Destes, 25,78% eram tabagistas e 39,11% tabagistas e etilistas. O principal tratamento identificado foi a associação de cirurgia, quimioterapia e radioterapia. Observou-se que 49,10% dos óbitos foram em decorrência dessa neoplasia. O principal estádio patológico encontrado foi o quatro A (34,22%). Foi identificada maior sobrevida nos pacientes acima de 70 anos, cujo tratamento foi exclusivamente cirúrgico. Menor sobrevida foi identificada em indivíduos que tinham associação de hábitos (etilismo e tabagismo). Conclusões:Nossos resultados sugerem que a evolução à óbito foi o principal desfecho clínico e, isso pode estar relacionado aos hábitos comportamentais que influenciam diretamente o curso e prognóstico da doença. Ademais, destaca-se a importância do diagnóstico precoce a fim de reduzir óbitos e melhorar a qualidade de vida dos indivíduos, assim como a necessidade de implementar políticas educativas sobre os principais fatores de risco associados ao desenvolvimento dessa neoplasia (AU).


Introduction: Squamous cell carcinoma of the oral cavity and oropharynx is a common malignant epithelial neoplasm, accounting for most cases of head and neck tumors. It is related to behavioral habits, such as long-standing smoking and alcoholism, as well as to the human Papillomavirus infection. Objectives: This study aimed at describing the epidemiological profile of the patients diagnosed with this neoplasm in the Mossoró League for Studying and Combating Cancer. Methodology:An observational study with a cross-sectional design was carried out based on data present in the medical records and anatomopathological reports and in the Mortality Information System during the 2006-2018 period. The data were analyzed using the R Software, resorting to the Wilcoxon-Mann-Whitneytest for the inferential analyses and to the Kaplan-Meier method for survival analysis. Results: 225 medical records were analyzed: 70.22% belonging to men, 65.33% aged between 46 and 70 years old and white-skinned (51.57%). Of these, 25.78% were smokers and 39.11% were smokers and alcoholics. The main treatment identified was the association of surgery, chemotherapy and radiotherapy. It was observed that 49.10% of the deaths were due to this neoplasm. The main pathological stage found wasfour A(34.22%).Longer survival was identified in patients over 70 years of age, whose treatment was exclusively surgical. Shorter survival was identified in individuals who had associated habits (alcoholism and smoking). Conclusions:Our results suggest that evolution to death was the main clinical outcome; this can be related to the behavioral habits that exert a direct influence on the course and prognosis of the disease. Furthermore, the importance of early diagnosis is highlighted in order to reduce the number of deaths and improve the individuals' quality of life, as well as the need to implement educational policies on the main risk factors associated with the development of this neoplasm (AU).

ABSTRACT

El cáncer diferenciado de tiroides incluye el tipo papilar y folicular que representan más del 80% de los casos y tienen un excelente pronóstico. Existen varios subtipos histológicos y las variantes foliculares son probablemente las más comunes. La incidencia de cáncer papilar variante folicular ha ido en aumento. En un reporte de un solo centro, cerca del 40% de los cánceres papilares eran variantes foliculares1. El subtipo infiltrativo de la variante folicular presenta sectores que invaden el parénquima tiroideo no neoplásico y carece de una cápsula tumoral bien definida. Tiene un comportamiento biológico y un perfil molecular que es más similar al tumor papilar clásico2. Existen características clínicas y patológicas asociadas con riesgo más alto de recurrencia tumoral y mortalidad; entre ellos se describen el tamaño del tumor primario y la presencia de invasión de tejidos blandos3. En la invasión de estructuras adyacentes, los sitios más comprometidos incluyen los músculos pretiroideos, el nervio laríngeo recurrente, el esófago, la faringe, laringe y la tráquea. Además, puede haber otras estructuras involucradas como: la vena yugular interna, la arteria carótida y los nervios vago, frénico y espinal4. El compromiso de los ganglios linfáticos y la incidencia de metástasis ganglionares en adultos depende de la extensión de la cirugía. Entre los que se realizan una disección radical modificada del cuello, hasta el 80% tienen metástasis en los ganglios linfáticos y el 50% de ellas son microscópicas5. Clínicamente los tumores localmente avanzados cursan con disfonía, disfagia, disnea, tos o hemoptisis, pero la ausencia de síntomas no descarta la invasión local. Según las guías de la American Thyroid Association6 son variables de mal pronóstico: la edad del paciente, el tamaño del tumor primario, la extensión extra tiroidea y la resección quirúrgica incompleta.


Differentiated thyroid cancer includes papillary and follicular types that represent more than 80% of cases and have an excellent prognosis. There are several histologic subtypes, and follicular variants are probably the most common. The incidence of papillary follicular variant cancer has been increasing. In a singlecenter report, about 40% of papillary cancers were follicular variants1. The infiltrative subtype of the follicular variant presents sectors that invade the non-neoplastic thyroid parenchyma and lacks a well-defined tumor capsule. It has a biological behavior and a molecular profile that is more similar to the classic papillary tumor2. There are clinical and pathological characteristics associated with a higher risk of tumor recurrence and mortality; These include the size of the primary tumor and the presence of soft tissue invasion3. In the invasion of adjacent structures, the most compromised sites include the pre-thyroid muscles, the recurrent laryngeal nerve, the esophagus, the pharynx, larynx and trachea. In addition, there may be other structures involved such as: the internal jugular vein, the carotid artery and the vagus, phrenic and spinal nerves4. The involvement of the lymph nodes and the incidence of lymph node metastases in adults depends on the extent of the surgery. Among those who undergo a modified radical neck dissection, up to 80% have lymph node metastases and 50% of them are microscopic5. Clinically locally advanced tumors present with dysphonia, dysphagia, dyspnea, cough, or hemoptysis, but the absence of symptoms does not rule out local invasion. According to the American Thyroid Association guidelines6, there are variables with a poor prognosis: the age of the patient, the size of the primary tumor, the extra-thyroid extension, and incomplete surgical resection.
