RESUMO
OBJECTIVE: To compare the oncological results and the functional outcomes of patients undergoing Total Laryngectomy (TL) with the non-surgical treatment (organ preservation protocol) in the treatment of advanced laryngeal carcinomas through systematic review and meta-analysis. METHODS: A literature survey strategy was employed in order to perform a systematic review of the available evidence. Success rate and functional outomes after oncological treatment of patients with advanced laryngeal carcinomas was evaluated through systematic review and metanalysis, comparing TL and organ preservation protocol. RESULTS: The surgical treatment was associated with better survival outcomes. When stratifying by T stage, while patients with T4 staging have less risk of mortality with TL, there is no difference between the different treatments for patients with T3 tumors. Surgery is related to a lower chance of recurrence, late dysphagia and feeding tube dependence. CONCLUSION: Patients with T4 tumors should undergo TL as their treatment of choice. For patients with T3 tumors, there is no differences on the risk of mortality according to the therapeutic option, however, there is a greater chance of recurrence and dysphagia when surgery is not performed.

RESUMO
Head and neck cancer (HNC) treatments have been based on single or multimodal therapies with surgery, radiotherapy (RT), chemotherapy, and immunotherapy. However, treatment recommendations among countries may differ due to technological/human resources and usual local practices. This scoping review aims to identify, compare, and map the clinical practice guidelines (CPGs) for treating squamous cell carcinoma (SCC) of the oral cavity, oropharynx, and larynx worldwide. A search strategy on global CPGs for HNC was performed by using five electronic databases and grey literature. CPGs were selected for inclusion using EndNote-20 and Rayyan online software. No language or publication date restrictions were applied. The results were analyzed descriptively considering the most updated CPG version. In total, 25 CPGs covering the head and neck region (10), the larynx (7), the oral cavity (5), and the oropharynx (3), were found in 13 geographical regions, and 19 were developed by medical societies from 1996 to 2023. Surgery and RT remain the main modalities for early-stage HNC, with surgery preferred in low-resource countries, and RT in selected cases, especially in the larynx/oropharynx aiming to achieve a cure with organ preservation. Human papillomavirus infection for oropharyngeal SCC is not tested in some Asian countries and there is still no consensus to treat p16-positive cases differently from p16-negative. Recommendations for larynx preservation vary according to facilities in each country, however, individualized choice is emphasized. Inequality across countries/continents is evident, with a similar pattern of recommendations among developed as well as developing ones. No CPGs were found in Latin America as well as Oceania countries, where the incidence of HNC is high and limitations of access to treatment may be encountered.
RESUMO
Abstract Objectives: This study aims to describe a new secondary tracheoesophageal puncture technique with voice prosthesis insertion under local anesthesia with a low-cost device and evaluate its outcome. Methods: With a transoral flexible transillumination device of aluminum of 2.3 mm with fiberoptic light, the esophagus's anterior wall is visualized through the tracheostomy. A tracheoesophageal fistula is made with a blade and passed through the fistula. Then a bent trocar is introduced into the lumen using the device as a guidewire. Once in the lumen, a thin guide wire is passed through up to the mouth. The voice prosthesis is positioned with retrograde insertion. Then, the patient is discharged without hospitalization. Results: 15 patients submitted to this technique had a successful surgical outcome. There were no complications as pneumothorax, esophageal perforation, bleeding, or hospitalization. Conclusion: The new device is feasible under local anesthesia.
RESUMO
Abstract Introduction: Lysyl oxidase-like 4 is an amine oxidase from the lysyl oxidase family that was previously shown to be overexpressed in head and neck cancer and upregulated in response to hypoxia. The possible role of lysyl oxidase-like 4 as a tumor marker in advanced stage larynx cancer was investigated. Objective: To investigate the expression of lysyl Oxidase-Like 4 protein in advanced stage laryngeal cancer and elucidate its possible role as a tumor marker, predictor of treatment response and prognosticator. Methods: Diagnostic specimens of 72 patients treated for stage III-IV laryngeal squamous cell carcinoma were evaluated for lysyl oxidase-like 4 expression by immunohistochemistry. Results: Lysyl oxidase-like 4 expression was correlated with advanced tumor stage (p = 0.041) and better differentiation (p = 0.025) but was independent of tumor diameter (p = 0.456). Response to induction chemotherapy or the need for salvage laryngectomy were not affected by lysyl oxidase-like 4 expression (p = 0.999, p = 0.070 respectively). Increased lysyl oxidase-like 4 expression was associated with better 2 year overall survival in both univariate (p = 0.036) and multivariate analyses (p = 0.014). Conclusion: Lysyl oxidase-like 4 expression emerges with advancing stages, is lost with worsening differentiation, and may have tumor suppressive properties in larynx cancer.
Resumo Introdução: A proteína tipo-lisil oxidase-4 é uma amina oxidase da família lisil oxidase cuja superexpressão em câncer de cabeça e pescoço e up-regulação em resposta à hipóxia foram previamente demonstradas. O possível papel da proteína tipo-lisil oxidase-4 como um marcador tumoral no câncer de laringe em estágio avançado foi investigado. Objetivos: Investigar a expressão da proteína tipo-lisil oxidase-4 no câncer de laringe em estágio avançado e elucidar seu possível papel como marcador tumoral, preditor da resposta ao tratamento e do prognóstico. Método: Amostras diagnósticas de 72 pacientes tratados para carcinoma espinocelular da laringe em estágio III-IV foram avaliadas quanto à expressão da proteína tipo-lisil oxidase-4 por imuno-histoquímica. Resultados: A expressão de proteína tipo-lisil oxidase-4 foi correlacionada com o estágio avançado do tumor (p = 0,041) e melhor diferenciação (p = 0,025), mas foi independente do diâmetro do tumor (p = 0,456). A resposta à quimioterapia de indução ou a necessidade de laringectomia de resgate não foram afetadas pela expressão da proteína tipo-lisil oxidase-4 (p = 0,999, p = 0,070 respectivamente). O aumento da expressão da proteína tipo-lisil oxidase-4 foi associado a melhor sobrevida global de 2 anos nas análises univariada (p = 0,036) e multivariada (p = 0,014). Conclusão: A expressão da proteína tipo-lisil oxidase-4 surge com o avanço dos estágios e desaparece com pioria da diferenciação e pode ter propriedades supressoras de tumor no câncer de laringe.
RESUMO
Tobacco and alcohol consumption are the main risk factors for head and neck cancer (HNC). However, some individuals do not have a history of addiction and even so they develop the disease. This study evaluated clinicopathological and prognostic features of non-smoking and non-drinking (NSND) HNC patients. A sample of smoking and/or drinking (SD) HNC patients was used to explore the differences with NSND patients. Data were obtained from 667 patients with squamous cell carcinoma in oral cavity, oropharynx or larynx. The group of NSND individuals represented 12.6% of the HNC patients and had higher prevalence of women and elderly compared to SD group. Among NSND patients, most of them displayed tumors in oral cavity, advanced clinical staging and absence of second primary tumor. NSND HNC patients had higher tumor recurrence and increased overall and specific survival rates at 5-years follow-up. The NSND group showed higher prevalence of tumors in lips and alveolar ridge, lower rate of tumors in floor of mouth and no tumor in soft palate. NSND patients show a distinct profile from that found in SD patients. Clinicopathological features from NSND patients should be considered for HNC management.

Abstract INTRODUCTION: Larynx cancer is one of the most common head and neck cancers, whose main risk factors are smoking and alcohol use, and its occurrence and prognosis depend on adequate and timely preventive measures. This study aimed to investigate the burden of larynx cancer in Brazil and its states. METHODS: Using estimates from the Global Burden of Disease Study 2019, this study analyzed the trends of incidence, mortality, and disability-adjusted life years (DALYs) for larynx cancer between 1990 and 2019, besides the mortality-to-incidence ratio and the socio demographic index. RESULTS: Incidence and mortality due to larynx cancer in Brazil, which are approximately eight-fold higher for men, showed a declining trend between 1990 and 2019 (APPC: -0.4% and -1.0%, respectively). The DALYs also showed negative variation between 1990 and 2019 for both sexes in Brazil, mainly due to the decrease in premature deaths, with the greatest reduction in the state of São Paulo. For the states of Brazil in 2019, the higher age-standardized incidence rate (Rio Grande do Sul, 3.83 cases per 100,000 inhabitants) is twice the lowest rate (Piauí, 1.56 cases per 100,000 inhabitants). CONCLUSIONS: A fall in the burden of larynx cancer was observed in Brazil over the past 30 years, which may be attributed to a reduction in smoking and to an improvement in treatment. However, the regional inequalities in the country remain evident, especially for males. This data can guide public policy priorities to control the disease in Brazil.
RESUMO
Abstract Introduction Narrow-band imaging is an endoscopic diagnostic tool that, focusing on superficial vascular changes, is useful to detect suspicious laryngeal lesions, enabling their complete excision with safe and tailored resection margins. Objectives To analyze the applications and benefits of narrow-band imaging in detecting premalignant and malignant laryngeal lesions through a comparison with white-light endoscopy. Data Synthesis A literature search was performed in the PubMed, Scopus and Web of Science databases using strict keywords. Then, two authors independently analyzed the articles, read the titles and abstracts, and read completely only the relevant studies according to certain eligibility criteria. In total, 14 articles have been included in the present review; the sensitivity, specificity, positive and negative predictive values, and accuracy of pre- and/or intraoperative narrow-band imaging were analyzed. The analysis showed that narrow-band imaging is better than white-light endoscopy in terms of sensitivity, specificity, positive and negative predictive values, and accuracy regarding the ability to identify cancer and/or precancerous laryngeal lesions. Moreover, the intraoperative performance of narrow-band imaging resulted more effective than the in-office performance. Conclusion Narrow-band imaging is an effective diagnostic tool to detect premalignant and malignant laryngeal lesions and to define proper resection margins. Moreover, narrow-band imaging is useful in cases of leukoplakia that may cover a possible malignant lesion and that cannot be easily assessed with white-light endoscopy. Finally, a shared, simple and practical classification of laryngeal lesions, such as that of the European Laryngological Society, is required to identify a shared lesion management strategy. Key Points Narrow-band imaging is useful in detecting suspicious laryngeal lesions and proper resection margins showing intraepithelial papillary capillary loops (IPCLs) that are considered a main cancer feature. Narrow-band imaging is used both pre- and intraoperatively, but it provides more precise information if used during surgery. Compared with white-light endoscopy, narrow-band imaging enables a better assessment of the lesions covered by a thick white plaque (such as in cases of leukoplakia) The classification of the European Laryngological Society is the simplest and the most practical for the identification of various laryngeal lesions compared with other classifications.

RESUMO
OBJECTIVE: The objective of the study was to analyze the results of endoscopic laser microsurgery for early glottic carcinoma treatment (Stages I and II) at a Tertiary Center in Mexico City. MATERIALS AND METHODS: Descriptive, retrospective review of 40 patients with early glottic carcinoma who were treated with endoscopic laser microsurgery with curative intent at our institution from November 2003 to December 2013. RESULTS: The study yielded 4 pTis, 19 pT1a, 8 pT1b, and 9 pT2 patients. Mean patient follow-up time was 7.4 years (range 3-12.9 years). Post-operative bleeding requiring surgical intervention occurred in 1 (2.5%) patient. Kaplan-Meier results at 3 and 5-year estimates were as follows: overall survival was 92.5 and 87%, respectively; laser only local control was 94.9 and 91.6%, respectively; and disease specific survival and ultimate local control rate were 97.5% for both time periods. We found a 97.5% (39/40) organ preservation rate. CONCLUSIONS: Laser microsurgery for glottic carcinoma treatment is an emerging technique in Mexico. Our results are promising as reported by other authors in Europe and United States of America, which support the replicability of the surgical technique refined by Dr. Wolfgang Steiner.
OBJETIVO: Analizar los resultados del tratamiento del carcinoma glótico temprano (estadios I y II) con microcirugía láser en un hospital de tercer nivel en Ciudad de México. MÉTODO: Estudio descriptivo y retrospectivo en 40 pacientes con cáncer glótico temprano tratados con microcirugía láser de noviembre de 2003 a diciembre de 2013. RESULTADOS: Se estudiaron 4 pTi, 19 pT1a, 8 pT1b y 9 pT2. El tiempo promedio de seguimiento fue de 7.4 años (rango: 3 - 12.9). Se presentó un sangrado posoperatorio con revisión quirúrgica (2.5%). Las curvas de Kaplan-Meier de estimación a 3 y 5 años mostraron una sobrevida total del 92.5 y 87%, respectivamente; control local solo con láser del 94.9 y 91.6%, respectivamente; sobrevida específica de la enfermedad y control local global del 97.5%, para ambos periodos de tiempo. El porcentaje de conservación del órgano fue del 97.5% (39/40). CONCLUSIONES: La microcirugía láser para el tratamiento del cáncer glótico temprano es una técnica que se aplica paulatinamente en México. Nuestros resultados son prometedores y equiparables a los reportados por otros autores en Europa y en los Estados Unidos de América, lo que sustenta la reproducibilidad de la técnica quirúrgica implementada por el Dr. Wolgang Steiner.

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.

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.

BACKGROUND: Definitive radiotherapy is an effective single-modality in T1 glottic cancer. Hypofractionated schemes could offer excellent results in a shorter treatment period. We aimed to evaluate the clinical outcomes and toxicity comparing conventional vs. hypofractionated radiotherapy treatment in T1N0M0-glottic cancer. PATIENTS AND METHODS: Between Jan-1st, 2005 and August-1st, 2017, in a prospective cohort study, with 10-year follow-up, 138 patients were treated with conventional schedule 2 Gy/day, total dose 70 Gy/7 weeks (N = 71) or hypofractionated schedule 2, 2-2, 25 Gy/day, total dose 63, 8-63 Gy/5, 5 weeks (N = 67). Endpoints were clinical-response rate, local relapse-free survival (LRFS), laryngectomy-free survival (LFS), toxicity rates, relapse-free survival (RFS), metastasis-free survival (MFS), second tumour-free survival (2TFS), and overall survival (OS). RESULTS: All patients showed a complete clinical response. No differences were found for LRFS (p = 0.869), LFS (p = 0.975), RFS (p = 0.767), MFS (p = 0.601), 2TFS (p = 0.293), or OS (p = 0.685). Acute toxicity for skin and mucosae was similar (p = 0.550 and p = 0.698). Acute laryngeal toxicity was higher in the hypofractionation group (p = 0.004), due to an increase in slight moderate grade. No differences in late laryngeal edema were found (p = 0.989). CONCLUSION: Radiotherapy offers high rate survival, local control, and larynx preservation after 5-10-year follow-up. A hypofractionation could be preferable, since it offers the same results as conventional with fewer treatment sessions.

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.

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.

Introducción: entre las diferentes modalidades terapéuticas para el carcinoma escamoso de laringe en estadios iniciales, la cirugía transoral láser (CTL) constituye el tratamiento de elección. El láser de CO2 es aceptado universalmente como la mejor herramienta terapéutica en este sentido. En situaciones de no poder acceder a esa tecnología, es posible utilizar otros instrumentos para resección en CTL (radiofrecuencia, electrobisturí). Entre estas, nuestro equipo de trabajo ha implementado el uso del láser de diodo de 1470 nm. En el presente trabajo describimos los resultados preliminares en el tratamiento de estadios tempranos del carcinoma escamoso de laringe con CTL. Materiales y métodos: Se utilizó el láser de diodo de 1470 nm en pacientes adultos mayores realizados entre enero de 2012 y diciembre de 2015 en el Servicio de Otorrinolaringología del Hospital Dr. C. Milstein. Resultados: Se trataron 32 pacientes con cáncer de laringe, de los cuales se incluyeron 21, todos mayores de 65 años, con carcinoma escamoso de laringe estadio Tis T1 y T2 sin compromiso cervical ni metastásico y sin tratamiento oncológico previo. De los 21 pacientes incluidos, a 19 se les realizó una única intervención y dos fueron reintervenidos con la misma técnica. Conclusiones: El uso del láser diodo de 1470 nm para el tratamiento del carcinoma escamoso de laringe en estadios iniciales ha permitido controlar la enfermedad en los 21 pacientes intervenidos con esta tecnología, en un tiempo medio de seguimiento de 21 meses. La CTL con láser de diodo se presenta como una opción válida para el tratamiento del cáncer de laringe en estadios iniciales.
Introduction: among the different therapeutic modalities for squamous carcinoma of the larynx in early stages, transoral laser surgery (CTL) is the treatment of choice. Materials and methods: CO2 laser is universally accepted as the best therapeutic tool in this regard. In situations of not being able to access that technology, it is possible to use other CTL resection instruments (radiofrequency, electro-scalpel). Among these, our work team has implemented the use of 1470 nm diode laser. In the present work we describe the preliminary results in the treatment of early stages of squamous carcinoma of the larynx with CTL using 1470 nm diode laser in elderly patients performed between January 2012 and December 2015 at the Otorhinolaryngology Service of Dr. Hospital C. Milstein. Results: Thirty-two patients with laryngeal cancer were treated, including 21, all over 65 years old, with squamous carcinoma of the Tis T1 and T2 larynx without cervical or metastatic involvement and without prior cancer treatment. Of the 21 patients included, 19 were given a single intervention and two were retreated with the same techniqu Conclusions: The use of laser 1470 nm diode for the treatment of squamous carcinoma of the larynx in early stages has allowed the control of the disease in the 21 patients operated with this technology, in an average follow-up time of 21 months. The CTL with diode laser is presented as a valid option for the treatment of laryngeal cancer in initial stages.

La implementación en Cuba de técnicas quirúrgicas para el tratamiento del cáncer laríngeo con conservación del órgano ha ganado adeptos en los últimos años. La morbilidad por esta entidad en la provincia de Matanzas manifestó una incidencia ascendente en la quinta década de la vida, lo que justifica adoptar posiciones que permitan cambiar el curso de los acontecimientos y restaurar la salud, minimizando la mutilación, el sufrimiento y la sensación de amenaza vital. El objetivo de la presente investigación fue evaluar los resultados obtenidos con las técnicas de cirugía conservadora de laringe en el período comprendido de 2005 al 2012. Se realizó un estudio descriptivo de tipo transversal. El universo estuvo constituido por pacientes portadores de cáncer de laringe que cumplieron los criterios de inclusión, exclusión y salida. Treinta y cinco pacientes fueron sometidos a cirugía parcial de laringe. Se apreció un predominio de pacientes con cáncer de laringe del sexo masculino, blancos y con edades comprendidas entre 45 y 60 años. Se reiteró la estrecha relación entre el cáncer de laringe y los hábitos tóxicos. El sitio de más frecuente de localización del tumor fue la glotis. El carcinoma de células escamosas es el diagnóstico histopatológico más representado. La técnica quirúrgica más empleada en nuestro centro y la de mejores resultados oncológicos fue la cordectomía. La evolución postquirúrgica fue favorable en un 74,3 %.
The use of surgical techniques for the larynx cancer treatment with that organ conservation has got adepts in the last years in Cuba. Morbidity caused by this entity in the province of Matanzas showed an increasing incidence in the fifth decade of life. It validates the adoption of positions that allow changing the disease course and restoring health, minimizing mutilation, suffering and the sense of life threatening at the same time. The aim of the current research was assessing the results obtained with the larynx conservative technique in the period from 2005 till 2012. A cross-sectional, descriptive study was carried out. The universe was formed by patients with larynx cancer fulfilling the inclusion, exclusion and exit criteria. Thirty-five patients were object of larynx partial surgery. It was appreciated an increase of male, white patients, aged 45-60 years, with larynx cancer. It was stated again the tight relation between larynx cancer and toxic habits. The most common cancer location was the glottis. The squamous cell carcinoma was the most represented histopathologic diagnosis. Cordectomy was the most used surgical technique in our hospital and the one showing the best oncologic results. The postsurgical evolution was favorable in 74.3 % of the cases.
RESUMO
La utilización del LASER de CO2 en laringología comenzó en la década del 80, permitiendo la exéresis de tumores por vía transoral. Su indicación se basa en los excelentes resultados oncológicos. La función deglutoria postquirúrgica es un factor importante en la calidad de vida de los pacientes con cáncer del tracto aerodigestivo superior. Los resultados de la deglución son relevantes para elegir la modalidad terapéutica, la cual debe ser no sólo efectiva en controlar el cáncer sino también en preservar la función del órgano. El grado y el tipo de alteración deglutoria deben ser determinados en forma precisa, para establecer el tratamiento postoperatorio adecuado. Esto es posible mediante estudios como la videodeglución y la evaluación endoscópica de la deglución (FEESST)...
The CO2 laser have been used for treatment of laryngeal cancers since 1980, with excellent oncological results. The swallowing plays an important roll in superior aerodigestive cáncer patient. Swallowing results are relevant to choose the therapeutic modality, which must be effective in controlling not only cancer but also in preserving organ function. The degree and type of swallowing impairment must be determined precisely, to establish the appropriate postoperative treatment. This is possible through studies like videodeglucion and endoscopic evaluation of swallowing (FEESST)...

Introducción: La laringoscopía directa (LD) se considera indispensable en el estudio del cáncer de laringe, tanto para precisar la extensión como para tomar biopsia. Objetivo: Demostrar que el resultado de biopsias tomadas por videonasofibroscopía (VFC) en cáncer de laringe es equivalente al de la biopsia definitiva. Material y método: Revisión de fichas de 53 pacientes del Servicio de Otorrinolaringología HBLT con sospecha de cáncer de laringe con biopsia realizada por VFC y definitiva, durante julio 2007 a diciembre 2011. Resultados: La muestra se compone mayormente por hombres de edad promedio 66 años, con consumo de tabaco en 63% y alcohol en 55,3%. Con correlación positiva entre biopsias para cáncer en 32 pacientes, 8 falsos negativos y 2 falsos positivos. Todas las muestras con cáncer fueron carcinoma escamoso. El 55% moderadamente diferenciado. Los falsos negativos no se encontraban en un estadio en particular. La sensibilidad de biopsia por VFC fue de 0,8 y la especificidad de 0,85. El LR fue de 5,2. Conclusión: Debe incluirse como parte del estudio ambulatorio ante la sospecha, ya que orienta el tratamiento inicial. Permite realizar la LD en el acto del tratamiento quirúrgico, así como evitarla en pacientes sin opción curativa quirúrgica, vía aérea difícil o alto riesgo anestésico.
Introduction: Direct laryngoscopy (DL) is considered essential in the study of the larynx cancer, both to specify local extension and in order to perform a biopsy. Aim: Show that the result of biopsies taken by videolaringoscopy (VL) in larynx cancer is equivalent to the definitive biopsy. Material and methods: Review of 53 patients charts of HBLT Otorhinolaryngology Service with suspected larynx cancer where the biopsy is performed by VL, during July 2007 to December 2011. Results: The patients included, are characterized by being mostly men with an average age of 66 years, with tobacco consumption by 63% and alcohol by 55.3%. There was a congrunence between positive biopsies for cancer in 32 patients, 8 false negatives and 2 false positives. All samples which tested positive for cancer were squamous cell carcinoma, 55% moderately differentiated. The patients that had false-negative results were not in a particular stage. The sensitivity was 0.8 and the specificity 0.85. The LR was 5.2. Conclusion: VL must be included as part of the ambulatory studies orienting the initial treatment when larynx cancer is suspected. VL allows to perform the DL in the act of surgical treatment, and avoid it in patients without surgical curative option, difficult airway or high anesthetic risk.
