ABSTRACT

Abstract Introduction: Upper airway obstruction, secondary to neoplasms presenting with stridor, is traditionally treated by tracheostomy. However, this common procedure can potentially have an impact on the long-term outcome, with tumor implantation into the tracheostomized wound leading to peristomal recurrence after laryngectomy, with the risk of stomal recurrence. Objective: To describe our clinical experience with tumor debulking as an alternative treatment choice of tracheotomy in patients with advanced larynx cancer at a tertiary referral center. Methods: A retrospective chart review of 87 subjects who had advanced larynx cancer (T3/4) with airway obstruction from our institutional database was conducted. Medical records including demographics, daily notes during hospitalization, and operative notes were used for clinical data of patients. The strategy for maintaining the airway patency was tracheotomy (emergency or awake) and tumor debulking (laser or coblation). Endophytic and exophytic laryngeal tumors were also noted. Results: In 41/87 (47.1%) patients, a tracheotomy was performed as an initial treatment (11 were emergency, 30 were planned) to maintain airway patency. Tumor debulking was performed in 28 exophytic and 18 endophytic lesions by laser or coblation (17 and 29 patients, respectively). Tracheotomy was performed in 5 patients (4 endophytic, 1 exophytic) who could not tolerate debulking surgery due to aspiration, edema and dyspnea. Three of the them who required subsequent tracheotomy was in the laser group and two in the coblation group. The success rate of laser debulking was 82.35% (14/17) and 93.1% (27/29) for coblation. Conclusion: Tumor debulking is a safe and effective method to avoid awake tracheotomy in patients suffering from airway obstruction due to advanced larynx cancer.


Resumo Introdução: A obstrução das vias aéreas superiores com estridor, secundária a neoplasias, é tradicionalmente tratada com traqueotomia. No entanto, este procedimento comum pode potencialmente ter um impacto sobre o desfecho a longo prazo, com a implantação do tumor na ferida cirúrgica da traqueotomia, o que leva à recorrência peristomal após laringectomia, com o risco de recorrência do estoma. Objetivo: Descrever nossa experiência clínica com a redução do volume tumoral como tratamento alternativo à traqueotomia em pacientes com câncer avançado de laringe em um centro de referência terciário. Método: Foi realizada uma revisão retrospectiva de prontuários de 87 indivíduos com câncer avançado de laringe (T3/T4) com obstrução das vias aéreas em nosso banco de dados institucional. Registros médicos incluindo dados demográficos, anotações diárias durante a hospitalização e anotações operacionais foram utilizados como dados clínicos dos pacientes. A estratégia para manter a patência das vias aéreas foi a traqueotomia (emergência ou em pacientes acordados) e redução do volume tumoral (por laser ou coblation). Tumores endofíticos e exofíticos da laringe também foram anotados. Resultados: Uma traqueotomia foi realizada como tratamento inicial em 41/87 (47,1%) pacientes (11 foram de emergência, 30 foram eletivas) para manter a patência das vias aéreas. A redução do volume tumoral foi realizada em 28 lesões exofíticas e 18 endofíticas por laser ou coblation (17 e 29 pacientes, respectivamente). A traqueotomia foi realizada em 5 pacientes (4 endofíticos, 1 exofítico) que não podiam tolerar a cirurgia de redução de volume devido à aspiração, edema e dispneia. Três deles que necessitaram de uma traqueotomia subsequente estavam no grupo de laser e dois no grupo coblation. A taxa de sucesso da redução tumoral foi de 82,35% (14/17) para o laser e 93,1% (27/29) para coblation. Conclusão: A redução do volume tumoral é um método seguro e eficaz para evitar a traqueotomia com paciente acordado, nos casos de obstrução das vias aéreas devido ao câncer de laringe avançado.

ABSTRACT

RESUMO Em tumores transglóticos estendidos para base de língua, a indicação para ressecção do osso hioide descarta a possibilidade de realização de uma laringectomia parcial horizontal clássica, devido ao grande risco de complicações pulmonares oriundas de uma disfagia grave. O objetivo deste estudo foi descrever os aspectos funcionais de deglutição e voz de um paciente submetido à laringectomia supratraqueal ampliada com cricoglossohioidopexia. Trata-se de um homem de 69 anos, com tumoração transglótica na hemilaringe direita, submetido à laringectomia supratraqueal ampliada, com ampliação para base de língua, osso hioide e aritenoide direita. Na videofluoroscopia da deglutição, observou-se aspiração silente para líquido fino durante a deglutição e resíduo em base de língua, valécula, aritenoide, esfíncter esofágico superior e recessos piriformes em todas as consistências e volumes. Na videolaringoscopia, observou-se voz por meio da vibração da unidade cricoaritenóidea esquerda, associada à base de língua e constritores da faringe. No protocolo Consensus Auditory-Perceptual Evaluation of Voice (CAPE V), notou-se grau moderado de rouquidão e soprosidade. O paciente apresentou preservação parcial das funções laríngeas, grau moderado de disfonia e alimentação e hidratação exclusivas por via oral, com sólidos macios e líquido espessado em néctar, sem prejuízos à saúde pulmonar, até o momento.


ABSTRACT In transglottic tumors extended to the base of the tongue, the indication for resection of the hyoid bone rules out the possibility of performing a classic horizontal partial laryngectomy due to the high risk of pulmonary complications resulting from severe dysphagia. This study aims to describe the functional aspects of swallowing and voice of a patient undergoing an enlarged supratracheal laryngectomy with cricoglossohioidopexy. This is a 69-year-old man with a transglottic tumor in the right hemilarynx, who underwent an extended supratracheal laryngectomy with enlargement to the base of the tongue, hyoid bone and right arytenoid. In swallowing videofluoroscopy, silent aspiration was observed in fine liquid and residue on the basis of tongue, valecule, arytenoid, upper esophageal sphincter and pyriform recesses in all consistencies and volumes. In videolaryngoscopy, a voice was observed through the vibration of the left cricoarytenoid unit associated with the base of the tongue and constrictors of the pharynx. The Consensus Auditory-Perceptual Evaluation of Voice (CAPE V) showed a moderate degree of hoarseness and breathiness. The patient had partial preservation of laryngeal functions, with a moderate degree of dysphonia and exclusive oral feeding and hydration with soft solids and thickened liquid in nectar without impairing lung health until the study.

ABSTRACT

ABSTRACT: Objective: To investigate the association between aging and the functional aspects of swallowing (laryngeal penetration and laryngotracheal aspiration) in individuals who underwent supracricoid laryngectomy in the late period and without complaints. Methods: A total of 70 patients, 56 (80%) aged >60 years and 14 (20%) <60 years, under outpatient follow-up, after cancer treatment and with no complaints of swallowing, performed functional evaluation using the swallowing videofluoroscopy. Image classification was performed using the penetration-aspiration scale developed by Rosenbek. The χ2 test and logistic regression were applied to associate the age categories to the outcomes (penetration and aspiration). Results: Patients aged over 60 years had a higher prevalence of penetration (24.29%) and aspiration (48.57%) than patients aged under 60 years. In this sample, aspiration was associated with age. Patients aged over 60 years were more likely to present penetration (27% more) during swallowing than patients under 60 years. Patients aged over 60 years had an approximately four-fold greater probability of laryngotracheal aspiration than patients aged under 60 years. Conclusion: In patients without complaints of swallowing in the late postoperative period of supracricoid laryngectomy, there is a greater probability of laryngotracheal aspiration in elderly aged over 60 years than in individuals under 60 years.


RESUMO Objetivo: Investigar a associação entre o envelhecimento e os aspectos funcionais da deglutição (penetração laríngea e aspiração laringotraqueal) em indivíduos submetidos à laringectomia supracricóidea no período tardio e sem queixas. Métodos: Setenta pacientes, sendo 56 (80%) >60 anos e 14 (20%) <60 anos, em acompanhamento ambulatorial, após tratamento oncológico e sem queixas de deglutição, realizaram avaliação funcional por meio da videofluoroscopia da deglutição. A classificação das imagens foi realizada por meio da escala de penetração-aspiração desenvolvida por Rosenbek. O teste do χ2 e a regressão logística foram aplicados para associação das categorias de idade aos desfechos (penetração e aspiração). Resultados: Os pacientes com idade acima de 60 anos apresentaram maior prevalência de penetração (24,29%) e aspiração (48,57%) do que aqueles com idade inferior a 60 anos. Nesta amostra, a aspiração se mostrou associada à idade. Pacientes acima de 60 anos tiveram chance 27% maior de penetração durante a deglutição do que os com menos de 60 anos. Pacientes acima de 60 anos tiveram chance aproximadamente quatro vezes maior de aspiração laringotraqueal do que pacientes com menos de 60 anos. Conclusão: Em pacientes sem queixas de deglutição no pós-operatório tardio de laringectomia supracricóidea, há maior chance de aspiração laringotraqueal em idosos acima de 60 anos do que em indivíduos abaixo de 60 anos.

ABSTRACT

Resumen Los plasmocitomas solitarios son una rara forma de presentación de neoplasias de células plasmáticas. Deben ser diferenciados del mieloma múltiple en el momento del diagnóstico y realizar un seguimiento estricto por el riesgo de transformación a mieloma. La localización de los mismos en la laringe es muy inusual, dado que sólo se han publicado 56 casos. Se presenta el caso de una paciente con un plasmocitoma extramedular de laringe que se trató mediante cirugía y radioterapia. Se revisan los criterios diagnósticos y los problemas terapéuticos.


Abstract Solitary plasmacytomas are a rare form of plasma cell neoplasms. They should be differentiated from multiple myeloma at the time of diagnosis and strictly monitored for the risk of transformation to myeloma. Their location in the larynx is very unusual, since only 56 cases have been published. We present the case of a patient with extramedullary plasmacytoma of the larynx that has been treated with surgery and radiotherapy. We reviewed the literature for diagnostic criteria and therapeutic problems.

ABSTRACT

Abstract Introduction Stomal recurrence is a troublesome complication after total laryngectomy. Despite a large number of studies having been performed, there is still controversy about which risk factors are most significant for the development of stomal recurrence. Objective The objective of the present meta-analysis was to analyze the potential factors leading to stomal recurrence after total laryngectomy. Methods PubMed, Web of Science, Cochrane Library, and Ovid databases were systematically searched using multiple search terms. Eighteen studies with 6462 patients were identified. The quality of evidence was assessed by The National Institute for Health and Clinical Excellence. Results The results showed that, tumor subsite (supraglottic vs. subglottic, RR = 0.292, 95% CI 0.142-0.600, p = 0.001; glottic vs. subglottic, RR = 0.344, 95% CI 0.175-0.676, p = 0.002), T stage (RR = 0.461, 95% CI 0.286-0.742, p = 0.001), preoperative tracheotomy (RR = 1.959, 95% CI 1.500-2.558, p < 0.001) were the high-risk factors associated with the development of stomal recurrence. Conclusion From the results of our study, tumor subsite, T stage and preoperative tracheotomy were the significant risk factors for stomal recurrence. Methodologically high-quality comparative investigations are needed for further evaluation.


Resumo Introdução A recorrência estomal pós-laringectomia total e é uma complicação de difícil manejo. Apesar de um grande número de estudos ter sido feito, ainda há controvérsias sobre quais fatores de risco são mais significativos para o seu desenvolvimento. Objetivo O objetivo da presente meta-análise foi analisar os fatores potenciais para recorrência estomal após a laringectomia total. Método As bases de dados PubMed, Web of Science, Cochrane Library e Ovid foram sistematicamente pesquisadas com vários termos de busca. Dezoito estudos com 6.462 pacientes foram identificados. A qualidade da evidência foi avaliada pelo National Institute for Health and Clinical Excellence. Resultados Os resultados mostraram que o subsítio tumoral (supraglótico vs. subglótico, RR = 0,292, IC 95% 0,142 ± 0,600, p = 0,001; glótico vs. subglótico, RR = 0,344, IC 95% 0,175 ± 0,676, p = 0,002), estágio T (RR = 0,461, IC 95% 0,286 ± 0,742, p = 0,001), traqueotomia pré-operatória (RR = 1,959, IC 95% 1.500 ± 2.558, p < 0,001) foram os fatores de alto risco associados ao desenvolvimento de recorrência estomal. Conclusão Com base nos resultados de nosso estudo, o subsítio do tumor, o estágio T e a traqueotomia pré-operatória foram fatores de risco significativos para recorrência estomal. São necessárias investigações comparativas metodologicamente de alta qualidade para maior avaliação.

ABSTRACT

Abstract Introduction: Pharyngocutaneous fistula is the most significant complication after salvage total laryngectomy in patients who have received previous treatment with radiotherapy with or without chemotherapy. Objective: Our purpose is to review the fistula rate in radiated patients undergoing salvage total laryngectomy, to determine if the use of pectoralis major flap interposition reduces the incidence and duration of fistula and to examine other risk factors. Methods: We made a retrospective review of patients undergoing salvage total laryngectomy for exclusively larynx cancer after failure of primary curative radiotherapy between 2000 and 2017. General data from patients, risk factors and other complications were analyzed. Results: We identified 27 patients whose mean age was 66.4 years, mainly male (92.5%). The primary closure group without pectoralis major flap included 14 patients, and the group with pectoralis major flap closure included 13 patients. Pharyngocutaneous fistula was present in 15 patients (55.5%). Global pharyngocutaneous fistula rate was higher in the group of patients without pectoralis major flap comparing with those were the flap was interposed (78.6% versus 30.8%, p = 0.047). Also the pharyngocutaneous fistulas which need to be repaired with surgery (64.3% versus 7.7%, p = 0.03) and large pharyngostomes (64.3% versus 0%, p = 0.0004) were present in a higher rate in the group closed primary without pectoralis major flap. We did not find other risk factors with statistical significance. Oral diet initiation (84 days versus 21.5 days, p = 0.039) and the duration of hospitalization (98.3 days versus 27.2 days, p = 0.0041) were much lower in patients with a preventive pectoralis major flap. Two patients died as a consequence of complications of large pharyngostomes. Conclusions: Prophylactic pectoralis major flap reduced the incidence, severity and duration of fistula and should be considered during salvage total laryngectomy.


Resumo Introdução: A fístula faringocutânea é a complicação mais significativa após laringectomia total de resgate em pacientes que receberam tratamento prévio com radioterapia com ou sem quimioterapia. Objetivo: Revisar a taxa de fístula em pacientes irradiados submetidos a laringectomia total de resgate, para determinar se o uso de interposição de retalho do peitoral maior reduz a incidência e a duração da fístula e examinar outros fatores de risco. Método: Fizemos uma revisão retrospectiva de pacientes submetidos à laringectomia total de resgate para câncer exclusivamente laríngeo após falha da radioterapia curativa primária entre 2000 e 2017. Dados gerais dos pacientes, fatores de risco e outras complicações foram analisados. Resultados: Foram identificados 27 pacientes com média de 66,4 anos, principalmente do sexo masculino (92,5%). O grupo de fechamento primário sem retalho de peitoral maior incluiu 14 pacientes e o grupo de fechamento com retalho de peitoral maior incluiu 13 pacientes. Fístula faringocutânea esteve presente em 15 pacientes (55,5%). A taxa global de fístula faringocutânea foi maior no grupo de pacientes sem retalho de peitoral maior em comparação com aqueles que receberam o retalho (78,6% vs. 30,8%, p = 0,047). Além disso, as fístulas faringocutâneas que precisaram ser reparadas através de cirurgia (64,3% vs. 7,7%, p = 0,03) e grandes faringostomias (64,3% vs. 0%, p = 0,0004) apresentaram uma taxa mais alta no grupo fechado primariamente sem retalho do peitoral maior. Não encontramos outros fatores de risco com significância estatística. O início da dieta oral (84 dias vs. 21,5 dias, p = 0,039) e a duração da internação (98,3 dias vs. 27,2 dias, p = 0,0041) foram muito menores nos pacientes com uso preventivo do retalho do peitoral maior. Dois pacientes morreram em consequência de complicações de grandes faringostomias. Conclusões: O uso profilático do retalho do peitoral maior reduziu a incidência, a gravidade e a duração da fístula e deve ser considerado durante a laringectomia total de resgate.

ABSTRACT

Se realizó un estudio prospectivo y descriptivo, incluyendo 103 pacientes que fueron tratados por cáncer de laringe en etapa inicial (T1-T2) con cirugía transoral. De ellos, 55 se diagnosticaron en estadio T1, 16 en estadio T1-b y 32 en estadio T2. El control local inicial (CLI) en pacientes con tumores malignos de laringe estadificados T1 fue 91%, el control local con rescate (CLR) 96%, la preservación de la función de la laringe (PFL) 93% y la sobrevida específica 96%. En T1-b, el CLI fue 81%, el CLR 94%, la PFL 94% y la sobrevida específica 94%. En T2, el CLI fue 63%, el CLR 94%, la PFL 72% y la sobrevida específica 78%. La cirugía transoral en cáncer de laringe con T inicial tiene resultados oncológicos similares a otros tratamientos (cirugía externa o radioterapia), pero consideramos que es la mejor opción por su baja morbilidad, menor duración del tratamiento, y porque deja abiertas todas las posibilidades para tratar posibles recurrencias. (AU)


A prospective and descriptive study was conducted, including 103 patients who were treated for early stage laryngeal cancer (T1-T2) with transoral surgery. Of these, 55 were diagnosed in stage T1, 16 in stage T1-b and 32 in stage T2. The initial local control (CLI) in patients with malignant T1 laryngeal tumors was: 91%, local control with rescue (CLR) 96%, preservation of larynx function (PFL) 93% and specific survival 96%. In T1-b the CLI was 81%, the CLR 94%, the PFL 94% and the specific survival 94%. In T2 the CLI was 63%, the CLR 94%, the PFL 72% and the specific survival 78%. Transoral surgery in laryngeal cancer with initial T has oncological results similar to other treatments (external surgery or radiotherapy), but we consider that it is the best option because of its low morbidity, shorter duration of treatment, and because it leaves open all the possibilities to treat possible recurrences.

ABSTRACT

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

ABSTRACT

ABSTRACT Objective To describe functional and quality of life results after extended supratracheal laryngectomy. Methods In the period from September 2009 to January 2018, 11 male subjects were submitted to extended supratracheal laryngectomy. Swallowing abilities were assessed through videofluoroscopy and the clinical scale Functional Communication Measures of Swallowing. The voices were classified by means of the perceptual-auditory analysis Consensus Auditory-Perceptual Evaluation of Voice. All subjects completed a self-assessment questionnaire for voice and swallowing. Results Aspiration was found in four patients and all presented stasis in different structures. All subjects in this study were exclusively orally fed and hydrated. In the evaluation of quality of life in swallowing, patients had mean >80 in all areas (83.47 mean of scores). The general degree and the presence of roughness were the highest means present in Consensus Auditory-Perceptual Evaluation of Voice (37.81 and 49.36, respectively). The mean of 33.36 (±22.56) had little impact on quality of life under the perspective of vocal aspects. Conclusion After supratracheal laryngectomy, swallowing was sufficiently restored and the quality of life was satisfactory. The voice presents severely impaired quality and preserved oral communication, with low impact on the activities of daily living. All individuals who maintained two cricoarytenoid units presented better functional results in swallowing and voice.


RESUMO Objetivo Descrever os resultados funcionais e de qualidade de vida após a laringectomia supratraqueal alargada. Métodos No período de setembro de 2009 a janeiro de 2018, 11 indivíduos do sexo masculino foram submetidos à laringectomia supratraqueal alargada. As habilidades de deglutição foram avaliadas por meio da videofluoroscopia e da escala clínica Functional Communication Measures . As vozes foram classificadas por análise perceptivo-auditiva da Consensus Auditory-Perceptual Evaluation of Voice . Todos os voluntários preencheram um questionário de autoavaliação para voz e deglutição. Resultados A aspiração foi encontrada em quatro pacientes, e todos apresentaram estase em diferentes estruturas. Todos os sujeitos deste estudo apresentavam alimentação e hidratação exclusivas por via oral. Na avaliação da qualidade de vida na deglutição, os pacientes demonstraram médias >80 em todas as áreas (83,47 média dos escores). O grau geral e a presença de rugosidade foram os maiores escores médios na avaliação perceptivo-auditiva da voz (37,81 e 49,36 consecutivamente). A média de 33,36 (±22,56) demonstrou pouco impacto na qualidade de vida sob a perspectiva dos aspectos vocais. Conclusão Após a laringectomia supratraqueal, a deglutição foi suficientemente restaurada, e a qualidade de vida foi satisfatória. A voz apresenta qualidade gravemente comprometida com comunicação oral preservada, demonstrando baixo impacto nas atividades da vida diária. Todos os indivíduos que mantiveram duas unidades cricoaritenóideas apresentaram melhores resultados funcionais na deglutição e na voz.

ABSTRACT

RESUMO Objetivo investigar o possível impacto da angulação do osso hioide na segurança da deglutição de pacientes submetidos à laringectomia supracricóidea. Métodos série de casos de 13 adultos, entre 48 e 79 anos, majoritariamente homens (n=11), submetidos à laringectomia supracricóidea em pós-operatório inferior ou igual a dez meses. Realizaram videofluoroscopia da deglutição de 5 ml de líquido fino, 5 ml de alimento pastoso e sólido, em livre oferta. A medida do ângulo do osso hioide foi definida por duas linhas: uma tangente à margem superior do corpo do osso hioide e uma tangente ao ponto mais inferior de sua margem inferior, paralela ao plano horizontal da imagem. O desfecho de aspiração durante o exame seguiu a escala desenvolvida por Rosenbek et al. (1996). Resultados Dos 13 pacientes, 5 apresentaram aspiração silente e 8 não apresentaram aspiração. Dos 5 indivíduos com aspiração, apenas 1 manteve preservadas ambas as cartilagens aritenoides em sua reconstrução e a angulação do osso hioide foi abaixo de 60º, em todos os casos. Dos 8 indivíduos sem aspiração laringotraqueal, a maioria (n=5) apresentava as duas cartilagens aritenoides em sua reconstrução e a angulação do osso hioide foi acima de 60º, em todos os casos. Conclusão uma angulação maior que 60º do osso hioide parece favorecer a proteção das vias aéreas inferiores e promover maior segurança do mecanismo de deglutição.


ABSTRACT Purpose to investigate the possible impact of hyoid bone angulation on swallowing safety in patients undergoing supracricoid laryngectomy. Methods the case series comprised 13 adults, between 48 and 79 years-old, male in its majority (n=11), within ten months or less post-supracricoid laryngectomy and cricohyoidoepiglottopexy. All volunteers were submitted to videofluroscopy at rest and during swallowing of 5 ml of thin fluid, 5 ml of pureed consistency and dry solid food. Images were captured in lateral view. The hyoid angle was taken at rest and defined by two lines: a tangent to the upper margin of the body of the hyoid bone and a horizontal line, tangent to the lowest point of its lower margin. The aspiration was assessed using the scale developed by Rosenbek et al. (1996). Results five cases had silent aspiration and eight had no aspiration. In the group with silent aspiration, only one individual had both arytenoid cartilages preserved, while all individuals had the hyoid bone angle below 60º. In the group without aspiration, five individuals had both cricoarytenoids preserved, while all cases had the average hyoid bone angle above 60º. Conclusion the hyoid bone being at an angle greater than 60º seemed to increase the protection of the lower airways, promoting a safer swallowing mechanism.

ABSTRACT

Abstract Introduction: The post-laryngectomy state is characterized by several alterations in lung function. A reliable estimation of lung function can be very useful in laryngectomees to prevent postoperative complications and to evaluate the results of the treatment. Objective: Characterize the presence of respiratory functional disorders and the functional pattern of laryngectomees through the use of an extratracheal device. Methods: This transversal study included 50 patients submitted to total laryngectomy at least 6 months prior to this investigation, as the treatment of choice for laryngeal cancer. Results: 56% percent of the participants had altered breathing pattern, distributed as follows: 14 with obstructive pattern with no air trapping, 11 with obstructive pattern with air trapping and only 3 with restrictive pattern. On average, the diffusion decreased (74.3%) and airway resistance increased (121.7%) when compared to the expected average values for the Brazilian individuals. Conclusion: Most patients submitted to total laryngectomy present altered lung function, usually the obstructive type, frequently associated to a history of smoking.


Resumo Introdução: A condição pós-laringectomia é caracterizada por várias alterações na função pulmonar. Uma estimativa confiável da função pulmonar pode ser muito útil em pacientes laringectomizados para prevenir complicações após as intervenções cirúrgicas e avaliar os resultados do tratamento. Objetivo: Caracterizar a presença de distúrbios funcionais respiratórios e o padrão funcional de pacientes laringectomizados através do uso de um dispositivo extratraqueal. Método: Estudo transversal que incluiu 50 pacientes submetidos à laringectomia total pelo menos seis meses antes desta investigação, como tratamento de escolha para o câncer de laringe. Resultados: Dos participantes, 56% apresentavam padrão respiratório alterado, assim distribuídos: 14 com padrão obstrutivo sem aprisionamento aéreo, 11 com padrão obstrutivo e aprisionamento aéreo e apenas três com padrão restritivo. Em média, verificou-se que a difusão encontrava-se diminuída (74,3%) e a resistência das vias aéreas aumentada (121,7%) em relação aos resultados esperados em brasileiros. Conclusão: A maioria dos pacientes submetidos à laringectomia total apresenta função pulmonar alterada, do tipo obstrutiva, quase sempre associada a história de tabagismo.

ABSTRACT

Abstract Introduction: The treatment of laryngeal squamous cell carcinoma needs accurate risk stratification, in order to choose the most suitable therapy. The prognostic significance of resection margin is still highly debated, considering the contradictory results obtained in several studies regarding the survival rate of patients with a positive resection margin. Objective: To evaluate the prognostic role of resection margin in terms of survival and risk of recurrence of primary tumour through survival analysis. Methods: Between 2007 and 2014, 139 patients affected by laryngeal squamous cell carcinoma underwent partial or total laryngectomy and were followed for mean of 59.44 ± 28.65 months. Resection margin status and other variables such as sex, age, tumour grading, pT, pN, surgical technique adopted, and post-operative radio- and/or chemotherapy were investigated as prognostic factors. Results: 45.32% of patients underwent total laryngectomy, while the remaining subjects in the cohort underwent partial laryngectomy. Resection margins in 73.39% of samples were free of disease, while in 21 patients (15.1%) anatomo-pathological evaluation found one of the margins to be close; in 16 subjects (11.51%) an involved resection margin was found. Only 6 patients (4.31%) had a recurrence, which occurred in 83.33% of these patients within the first year of follow-up. Disease specific survival was 99.24% after 1 year, 92.4% after 3 years, and 85.91% at 5 years. The multivariate analysis of all covariates showed an increased mortality rate only with regard to pN (HR = 5.043; p = 0.015) and recurrence (HR = 11.586; p = 0.012). Resection margin did not result an independent predictor (HR = 0.757; p = 0.653). Conclusions: Our study did not recognize resection margin as an independent prognostic factor; most previously published papers lack unanimous, methodological choices, and the cohorts of patients analyzed are not easy to compare. To reach a unanimous agreement regarding the prognostic value of resection margins, it would be necessary to carry out meta-analyses on studies sharing definition of resection margin, methodology and post-operative therapeutic choices.


Resumo Introdução: O tratamento do carcinoma de células escamosas de laringe necessita de uma estratificação precisa do risco, para a escolha da terapia mais adequada. O significado prognóstico da margem de ressecção ainda é motivo de debate, considerando-se os resultados contraditórios obtidos em vários estudos sobre a taxa de sobrevida de pacientes com margem de ressecção positiva. Objetivo: Avaliar o papel prognóstico da margem de ressecção em termos de sobrevida e risco de recorrência de tumor primário através da análise de sobrevida. Método: Entre 2007 e 2014, 139 pacientes com carcinoma de células escamosas de laringe foram submetidos à laringectomia parcial ou total e foram acompanhados por um tempo médio de 59,44 ± 28,65 meses. O status de margem de ressecção e outras variáveis, como sexo, idade, grau do tumor, pT, pN, técnica cirúrgica adotada e radio- e/ou quimioterapia pós-operatória, foram investigados como fatores prognósticos. Resultados: Dos pacientes, 45,32% foram submetidos à laringectomia total, enquanto os demais foram submetidos à laringectomia parcial. As margens de ressecção em 73,39% das amostras estavam livres, enquanto em 21 pacientes (15,1%) a avaliação anatomopatológica encontrou uma das margens próxima e 16 indivíduos (11,51%) apresentaram margem de ressecção comprometida. Apenas seis pacientes (4,31%) apresentaram recidiva, o que ocorreu em 83,33% desses pacientes no primeiro ano de seguimento. A sobrevida doença-específica foi de 99,24% em um ano, 92,4% em três anos e 85,91% em cinco anos. A análise multivariada de todas as covariáveis mostrou um aumento na taxa de mortalidade apenas em relação à pN (HR = 5,043; p = 0,015) e recidiva (HR = 11,586; p = 0,012). A margem de ressecção não demonstrou ser um preditor independente (HR = 0,757; p = 0,653). Conclusões: Nosso estudo não identificou a margem de ressecção como fator prognóstico independente; a maioria dos artigos publicados anteriormente não tem escolhas metodológicas unânimes e as coortes de pacientes analisados não são fáceis de comparar. Para chegar a uma concordância unânime em relação ao valor prognóstico da margem de ressecção, seria necessário fazer metanálises em estudos que compartilham a definição da margem de ressecção, metodologia e escolhas terapêuticas pós-operatórias.

ABSTRACT

Abstract Introduction The main modalities of surgical treatment for laryngeal cancer include transoral laser microsurgery (TLM), open preservation surgery, and total laryngectomy (TL). In the elderly, for the presence of comorbidities, the surgical approach more appropriate in many cases remains TL. The use of a stapler for the closure of the esophagus has been introduced to reduce surgical time and postoperative complications such as pharyngocutaneous fistula (PCF). Objective In the present study, we have evaluated the effectiveness of the use of the horizontal mechanical pharyngoesophageal closure in patients who underwent TL. Methods This nonrandomized study was performed on consecutive patients with histopathologically proven squamous cell endolaryngeal carcinoma. The TLwas performed using a linear stapler to mechanically suture the pharyngotomy using the semiclosed technique. Results A total of 33 patients underwent TL, and 13 of themunderwent neck dissection. A total of 15 patients (45.4%) were ≤70 years old, and 18 were > 70 years old. Analyzing the results in relation to age, patients > 70 years old showed tumors at an earlier stage than those aged ≤70 years old. Furthermore, in this group there was a greater number of patients who had comorbidities (p = 0.014). In total, we had 2 (6%) cases of PCF in 6.6% in the group ≤70 years old, and in 5.5% of the group > 70 years old (p = 1.00). Conclusions The use of the stapler for the horizontal closure of the pharyngoesophagectomy in the patients subjected to TL is proven to be useful and safe even when used in elderly patients.

ABSTRACT

Abstract Introduction: Although the red cell distribution width has been reported as a reliable predictor of prognosis in several types of cancer, to our knowledge few reports have focused on the prognostic value of red cell distribution width in laryngeal carcinoma. Objective: We aimed to explore whether the pretreatment red cell distribution width predicted recurrence in laryngeal cancer patients is a simple, reproducible, and inexpensive prognostic biomarker. Methods: All laryngeal cancer patients who underwent curative surgery (n = 132) over a 7 year study period were evaluated. Data on demographics, primary tumor site, T-stage, N-stage, histological features (differentiation; the presence of perineural/perivascular invasion), treatment group (total laryngectomy or partial laryngectomy) or adjuvant therapy (chemotherapy/radiotherapy); laboratory parameters (complete blood count, including the pre-operative red cell distribution width), and disease-free survival rates were retrospectively reviewed. All cases were divided into three groups by the red cell distribution width tertile [<13% (25th percentile) (n = 31), 13-14.4% (50th percentile) (n = 72), and >14.4% (75th percentile) (n = 29)]. Results: High-red cell distribution width group included more patients of advanced age, and more of those with recurrent and metastatic tumors (p = 0.005, 0.048, and 0.043, respectively). Individuals with red cell distribution width >14.4% (75th percentile) had lower disease free survival rates than did those with red cell distribution width <13% (25th percentile) (p = 0.014). Patients with red cell distribution width >14.4% at diagnosis were at a higher risk of locoregional recurrence (hazard ratio = 5.818, 95% confidence interval (95% CI) 1.25-26.97; p = 0.024) than patients with a normal red cell distribution width (<13%). Conclusion: We found that the pretreatment red cell distribution width was independently prognostic of disease free survival rate in patients with laryngeal cancer and may serve as a new, accurate, and reproducible means of identifying early-stage laryngeal cancer patients with poorer prognoses.


Resumo Introdução: Embora a amplitude de distribuição de eritrócitos tenha sido relatada como um preditor confiável de prognóstico em vários tipos de câncer, que seja de nosso conhecimento, poucos estudos se concentraram no valor prognóstico dessa medida no carcinoma laríngeo. Objetivo: Avaliar se a amplitude de distribuição de eritrócitos pré-tratamento prevê a recorrência em pacientes com câncer de laringe como um biomarcador prognóstico simples, reprodutível e não dispendioso. Método: Foram avaliados todos os pacientes com câncer de laringe submetidos à cirurgia curativa (n = 132) durante sete anos. Dados demográficos, local do tumor primário, estágio T, estágio N, características histológicas (diferenciação; presença de invasão perineural/perivascular), grupo de tratamento (laringectomia total ou laringectomia parcial) ou terapia adjuvante (quimioterapia/radioterapia); parâmetros laboratoriais (hemograma, inclusive a amplitude de distribuição de eritrócitos pré-operatório) e a sobrevida livre de doença foram revisados retrospectivamente. Todos os casos foram divididos em três grupos pelo tercil da amplitude de distribuição de eritrócitos [< 13% (percentil 25) (n = 31), 13%-14,4% (percentil 50) (n = 72) e > 14,4% (percentil 75) (n = 29)]. Resultados: O grupo com amplitude de distribuição de eritrócitos elevado incluiu um número maior de pacientes com idade avançada e mais pacientes com tumores recorrentes e metastáticos (p = 0,005, 0,048 e 0,043, respectivamente). Os indivíduos com a amplitude de distribuição de eritrócitos > 14,4% (percentil 75) apresentaram taxas de sobrevida livre de doença menores do que aqueles com a amplitude de distribuição de eritrócitos < 13% (percentil 25) (p = 0,014). Pacientes com a amplitude de distribuição de eritrócitos > 14,4% no diagnóstico apresentaram maior risco de recorrência locorregional [Hazard Ratio = 5,818, intervalo de confiança de 95% (IC 95%) 1,25-26,97; p = 0,024] do que pacientes com a amplitude de distribuição de eritrócitos normal (< 13%). Conclusão: Verificamos que a amplitude de distribuição de eritrócitos pré-tratamento foi um fator prognóstico independente de sobrevida livre de doença em pacientes com câncer de laringe e pode servir como um novo parâmetro, preciso e reprodutível, para identificar pacientes com câncer de laringe em estágio inicial com piores prognósticos.

ABSTRACT

Abstract Introduction: Laryngeal cancer is the most common cancer of the upper respiratory tract. The main methods of treatment included surgery (partial laryngectomy and total laryngectomy) and radiation therapy. Laryngeal dysfunction is seen after both treatment modalities. Objective: The aim of the study is to compare postoperative functional results of the standard supracricoid partial laryngectomy technique and a modified supracricoid partial laryngectomy technique using the sternohyoid muscle. Methods: In total, 29 male patients (average years 58.20 ± 9.00 years; range 41-79 years) with laryngeal squamous cell carcinoma who underwent supra cricoid partial laryngectomy were included. The patients were divided into two groups in terms of the surgical techniques. In Group A, all patients underwent standard supracricoid partial laryngectomy technique between January 2007 and November 2011. In Group B, all patients underwent modified supracricoid partial laryngectomy between August 2010 and November 2011. Fiberoptic endoscopic evaluation of swallowing test, short version of the voice handicap index scores, and the MD Anderson dysphagia inventory, the time of oral feeding and the decanulation of the patients after surgery of each groups were compared. Results: The mean maximum phonation time was 8.68 ± 4.21 s in Group A and 15.24 ± 6.16 s in Group B (p > 0.05). The S/Z (s/s) ratio was 1.23 ± 0.35 in Group A and 1.08 ± 0.26 in Group B (p > 0.05); the voice handicap index averages were 9.86 ± 4.77 in Group A and 12.42 ± 12.54 in Group B (p > 0.05); the fiberoptic endoscopic evaluation of swallowing test averages were calculated as 12.73 ± 3.08 in Group A and 13.64 ± 1.49 in Group B (p > 0.05). In the MD Anderson dysphagia inventory, evaluation of swallowing, the emotional, physical, and functional scores were 29.21 ± 4.11, 32.21 ± 6.85, and 20.14 ± 2.17 in the Group B, and 29.20 ± 2.54, 32.4 ± 4.79, and 19 ± 1.92 in Group A, respectively. Conclusion: Although there is no statistical difference in functional outcome comparisons, if rules are adhered to in preoperative patient selection, modified supracricoid partial laryngectomy can be applied safely and meaningful gains can be achieved in functional outcomes.


Resumo Introdução: O câncer laríngeo é o câncer mais comum do trato respiratório superior. Os principais métodos de tratamento incluem cirurgia (laringectomia parcial e laringectomia total) e radioterapia. A disfunção laríngea é observada em ambas as modalidades de tratamento. Objetivos: Comparar os resultados funcionais pós-operatórios da técnica de laringectomia padrão supracricoide e a técnica de laringectomia supracricoide modificada com o uso do músculo esterno-hióideo. Método: Foram incluídos 29 pacientes do sexo masculino (média de 58,20 ± 9,00 anos, intervalo de 41 a 79) com carcinoma espinocelular de laringe submetidos à laringectomia supracricoide parcial. Os pacientes foram divididos em dois grupos em termos de técnicas cirúrgicas. Todos os pacientes do Grupo A foram submetidos à laringectomia padrão supracricoide entre janeiro de 2007 e novembro de 2011. No Grupo B, todos os pacientes foram submetidos à laringectomia supracricoide modificada entre agosto de 2010 e novembro de 2011. A avaliação endoscópica da deglutição por fibra ótica, os escores da versão curta do Voice Handicap Index e do MD Anderson Dysphagia Inventory, o tempo de alimentação oral e a decanulação dos pacientes foram comparados após a cirurgia em cada grupo. Resultados: A média do tempo máximo de fonação foi de 8,68 ± 4,21 segundos no Grupo A e 15,24 ± 6,16 segundos no Grupo B (p > 0,05). A razão S/Z (seg/seg) foi de 1,23 ± 0,35 no Grupo A e 1,08 ± 0,26 no Grupo B (p > 0,05); as médias do Voice Handicap Index foram 9,86 ± 4,77 no Grupo A e 12,42 ± 12,54 no Grupo B (p > 0,05); as médias da avaliação endoscópica da deglutição por fibra ótica foram calculadas como 12,73 ± 3,08 no Grupo A e 13,64 ± 1,49 no Grupo B (p > 0,05). Na avaliação da deglutição pelo MD Anderson Dysphagia Inventory, os escores emocional, físico e funcional foram 29,21 ± 4,11, 32,21 ± 6,85 e 20,14 ± 2,17 no Grupo B e 29,20 ± 2,54, 32,4 ± 4,79 e 19 ± 1,92 no Grupo A, respectivamente. Conclusão: Embora não haja diferença estatística nas comparações de resultados funcionais, se as regras forem respeitadas na seleção pré-operatória do paciente, a laringectomia supracricoide parcial modificada pode ser aplicada com segurança e ganhos significativos podem ser alcançados em termos de resultados funcionais.

ABSTRACT

Abstract Introduction: Trans-oral laser microsurgery is an established technique for the treatment of early and moderately advanced laryngeal cancer. Objective: The authors intend to test the usefulness of narrow-band imaging in the intraoperative assessment of the larynx mucosa in terms of specifying surgical margins. Methods: Forty-four consecutive T1-T2 glottic cancers treated with trans-oral laser microsurgery Type I-VI cordectomy were presented. Suspected areas (90 samples/44 patients) were biopsied under the guidance of narrow-band imaging and white light and sent for frozen section. Results: Our study revealed that 75 of 90 (83.3%) white light and narrow-band imaging-guided samples were histopathologically positive: 30 (40%) were confirmed as carcinoma in situ or invasive carcinoma and 45 (60%) as moderate to severe dysplasia. In 6 patients mucosa was suspected only in narrow-band imaging, with no suspicion under white light. Thus, in these 6 patients 18/90 (20%) samples were taken. In 5/6 patients 16/18 (88.8%) samples were positive in frozen section: in 6/18 (33.3%) carcinoma (2 patients), 10/18 (66.6%) severe dysplasia was confirmed (3 patients). In 1 patient 2/18 (11.1%) samples were negative in frozen section. Presented analysis showed, that sensitivity, specificity and accuracy of white light was 79.5%, 20% and 71.1% respectively, while narrow-band imaging was 100%, 0.0% and 85.7%, respectively. Conclusion: The intraoperative use of narrow-band imaging proved to be valuable in the visualization of suspect areas of the mucosa. Narrow-band imaging confirms the suspicions undertaken in white light and importantly, it showed microlesions beyond the scope of white light.


Resumo Introdução: A microcirurgia transoral a laser é uma técnica bem estabelecida para o tratamento de câncer de laringe inicial e moderadamente avançado. Objetivo: Verificar a utilidade da imagem de banda estreita na avaliação intraoperatória da mucosa laríngea na especificação das margens cirúrgicas. Método: Foram avaliados 44 cânceres glóticos T1-T2 consecutivos, tratados com cordectomia Tipo I-VI, por microcirurgia transoral a laser. As áreas suspeitas (90 amostras/44 pacientes) foram submetidas a biopsia e avaliadas através de imagens de banda estreita e luz branca e enviadas para cortes por congelação. Resultados: Nosso estudo revelou que 75 (83,3%) das 90 amostras apresentaram histopatologia positiva na análise com luz branca e imagens de banda estreita: 30 (40%) foram confirmadas como carcinoma in situ ou carcinoma invasivo e 45 (60%) como displasia moderada a grave. Em seis pacientes, a mucosa apresentou-se suspeita apenas na imagem de banda estreita, sem suspeita sob luz branca. Assim, nesses seis pacientes 18/90 (20%) amostras foram colhidas. Em 5/6 pacientes, 16/18 (88,8%) amostras mostraram resultado positivo na análise de congelação: em 6/18 (33,3%) amostras foi confirmado carcinoma (dois pacientes) e em 10/18 (66,6%) foi confirmada displasia grave (três pacientes). Em um paciente, 2/18 (11,1%) as amostras mostraram resultado negativo na congelação. A análise apresentada mostrou que a sensibilidade, a especificidade e a acurácia da luz branca foram de 79,5%, 20% e 71,1%, respectivamente, enquanto a imagem de banda estreita apresentou como resultados 100%, 0,0% e 85,7%, respectivamente. Conclusão: O uso intraoperatório de imagem de banda estreita provou ser valioso na identificação de áreas suspeitas da mucosa, confirmou as suspeitas verificadas na análise com luz branca e, o que é mais importante, identificou microlesões além do alcance da luz branca.

ABSTRACT

INTRODUCCIÓN: La laringectomía total es el tratamiento de elección del cáncer de laringe avanzado, requiriendo en ocasiones asociar una resección parcial o total de la faringe para su manejo. El defecto faríngeo, puede repararse con colgajos libres o pediculados, teniendo estos últimos la ventaja de ser simples, confiables y resistentes a la radioterapia. OBJETIVO: Presentar los resultados funcionales de una serie de pacientes tratados con faringolaringectomía y reconstrucción faríngea con colgajo pediculado. MATERIAL Y MÉTODO: Se revisaron registros de pacientes con laringectomía total más faringectomía parcial y reconstrucción con colgajo pediculado en el Hospital Regional de Talca entre 2009 y 2017, encontrando 6 casos de los cuales 4 se encontraron vivos al momento de iniciar el estudio. Se realizó videofluoroscopía para evaluar deglución, presencia de estenosis y/o fístulas, además, de evaluación nutricional y encuesta de calidad de vida. RESULTADOS: En el estudio de la deglución por fluoroscopía, todos los pacientes presentaron escasa retención del material de contraste en la hipofaringe y esófago cervical, lo cual está en relación con cambios morfológicos posquirúrgicos, sin afectar significativamente el mecanismo deglutorio. Todos los pacientes se encontraron eutróficos en su evaluación nutricional y sin evidencias de alteración de su calidad de vida secundaria a la deglución. CONCLUSIONES: La reconstrucción faríngea parcial con colgajo pediculado en pacientes con laringectomías totales asociadas a faringectomía parcial permite una deglución adecuada y sin disfagia, con un estado nutricional eutrófico.


INTRODUCTION: Total laryngectomy is the treatment of choice for advanced laryngeal cancer and after radiotherapy failure. In patients with pharyngeal invasion, it is associated with total or partial pharyngectomy, wich defect can be repaired with free or pedicle flaps. AIM: To present a brief series of pedicle flap reconstruction approach after pharyngolaryngectomy in laryngeal carcinoma patients and functional outcomes MATERIALS AND METHOD: We looked at laryngeal cancer patient records who were treated with total laryngectomy with partial pharyngectomy and pharyngeal reconstruction with pedicle flap at "Hospital Regional de Talca" between the years 2009 and 2017, finding 6 cases, 4 of which were alive at the beginning of the study. We analized videoflourocopy swallow studies to assess mechanisms of deglutition, and presence of stenosis or fistulas. We also performed a nutritional state assessment and a quality of life questionnaire. RESULTS: During videodeglutition study, the 4 patients showed minimal contrast swallow delay at hypopharynx and cervical esophagus. All the patients were found eutrophic in their nutritional assessment and with no significant evidence of quality of life disturbances secondary to deglutition state. CONCLUSIONS: Partial pharyngeal reconstruction using pedicle flaps in patients who underwent total laryngectomy with partial pharyngectomy allows to maintain an adequate deglutition without dysphagia, as well as a good nutritional state.

ABSTRACT

RESUMEN El cáncer de laringe avanzado y el cáncer de hipofaringe pueden ser tratados con terapia de conservación de órganos con radioquimioterapia, sin embargo, cuando esta última fracasa, la cirugía es la última opción para esta patología. El cáncer de hipofaringe posee una pobre sobrevida en estados avanzados, y su tratamiento quirúrgico después de radioterapia siempre se transforma en un desafío quirúrgico por las condiciones del tejido irradiado. Este artículo realiza una revisión general de las opciones de reconstrucción para defectos faringolaríngeos tanto parciales como circunferenciales, ante el caso eventual de que por la extensión tumoral y su tratamiento ablativo no sea posible un cierre primario. Se revisan distintos resultados de los principales colgajos utilizados en reconstrucción en cabeza y cuello, como son los colgajos libres fasciocutáneos, colgajo pectoral mayor y colgajos viscerales como el yeyuno, comparando tasas de fistulas faringocutáneas, resultados en deglución y rehabilitación fonatoria posterior, intentando realizar una aproximación a una recomendación terapéutica. Por último cabe mencionar que todo servicio de cabeza y cuello debe conocer las opciones existentes para cada paciente en particular, ya que además de buscar resultados oncológicos, se debe intentar lograr buenos resultados funcionales que no empobrezcan la calidad de vida de nuestros pacientes.


ABSTRACT Advanced laryngeal cancer and hypopharyngeal cancer can be treated with organ preservation therapy with radiochemotherapy. However, when the latter fails, surgery is the last option for this pathology. Hypopharyngeal cancer has a poor survival in advanced stages, and its surgical treatment after radiotherapy always becomes a surgical challenge due to the conditions of the irradiated tissue. This article makes a general review of the reconstruction options for both partial and circumferential pharyngolaryngeal defects, in the case where tumor extensions and ablative treatments do not permit a primary closure. Different results of the main flaps used in head and neck reconstruction are reviewed, such as the fasciocutaneous free flaps, pectoralis major flap and visceral flaps such as the jejunum. We then compare the rates of pharyngocutaneous fistulas, swallowing results and posterior phonation rehabilitation, while trying to perform an approach to a therapeutic recommendation. Finally, it should be mentioned that all head and neck services must know the existing options for each patient in particular, since in addition to looking for oncological results, one should try to achieve good functional results that do not impoverish the quality of life of our patients.

ABSTRACT

O lipossarcoma de laringe é uma neoplasia extremamente rara, acomete principalmente o sexo masculino, principalmente na quinta década de vida. Existindo apenas cerca de 40 casos descritos na literatura, desses nenhum em língua portuguesa. O presente caso relata o diagnóstico em um paciente do sexo masculino, 57 anos, ex-tabagista, apresentando alteração de voz e obstrução de via área. Foi optado por ressecção cirúrgica completa com achados sugestivos de lipossarcoma bem diferenciado. Foi optado por manter seguimento, não tendo sido indicado quimioterapia e radioterapia adjuvantes.(AU)


Laryngeal liposarcoma is an extremely rare neoplasm that affects especially men in the fifth decade of life. There are only about 40 cases described in the literature, none of them in the Portuguese language. We report the case of a 57-year-old, former smoker man presenting with voice disorders and airway obstruction. We opted for complete surgical resection with findings suggestive of well-differentiated liposarcoma. We chose to keep following the patient, and no adjuvant chemotherapy and radiotherapy were indicated. (AU)
