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.

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: The recently published 4th Edition of the World Health Organization Classification of Head and Neck Tumors addresses the most relevant and updated aspects of tumor biology, including clinical presentation, histopathology, immunohistochemistry, and prognosis of head and neck tumors. The objective of the present study is to compare these updates to the 3rd edition of that book with regard to mucosal melanomas and to highlight the potential factors that differ those tumors from cutaneous melanomas. We observed progress in the understanding of oral and sinonasal mucosal melanomas, which also present themselves, in the molecular scope, differently form cutaneous melanomas.

ABSTRACT

Câncer de laringe representa 2% de todas as lesões malignas e o seu prognóstico está diretamente relacionado à identificação precoce das lesões precursoras. Nesse contexto são apresentados dois parâmetros classificatórios das lesões pré-malignas (OMS e Ljubljana), assim como os parâmetros para o diagnóstico e tratamento clínico e/ou cirúrgico.


Laryngeal cancer represents 2% of all malignancies and their prognosis is directly related to early identification of precursor lesions. In this context two classificatory parameters of premalignant lesions (WHO and Ljubljana) are presented, as well as the parameters for the diagnosis and clinical treatment and/or surgical treatment.

ABSTRACT

Cancers of the upper aerodigestive tract (UADT) constitute 3.5-4% of all malignancies. Since the majority of cases are squamous cell carcinomas which are related with epidemiologic factors, a different pattern of UADT cancer might be present between the Western and Asian populations. We performed a pathology based statistical study on UADT cancers in Korean patients. Cases from Korea Cancer Center Hospital, from January 1, 1988 through December 31, 1998, were subjected to the study. Among 2,842 cases, epithelial malignancies accounted for 87.8%, with squamous cell carcinoma as the major type (76.5%). The larynx was the most commonly affected site (26%), followed by the oral cavity (25.1%), oropharynx (13%), nasopharynx (9%), hypopharynx (8.4%), paranasal sinuses (6.4%), nasal cavity (6%) and salivary glands (6.1%). The percentage of squamous cell carcinoma was highest (98.7%) at the hypopharynx, and lowest at the nasal cavity (42.3%), which showed the most diverse tumor entities. Korean patients with UADT cancers presented with a higher incidence of non-epidermoid malignancy including sarcoma (1.5%) and malignant melanoma (1.4%), and a higher frequency of involvement of the sinonasal tract, compared with the Western patients.

ABSTRACT

Los tumores malignos de la laringe tienen gran importancia en la patología maligna de cabeza y cuello. La pesquisa precoz es la clave en el tratamiento, lo cual lleva a un buen pronóstico, por otro lado el diagnóstico tardío conduce a cirugía en su mayoría mutilante con bajas probabilidades de sobrevida. En el presente trabajo se analizan sus aspectos epidemiológicos y etiopatogénicos de mayor relevancia. Junto a ello el análisis de los hallazgos clínicos que permiten el diagnóstico temprano y una etapificación adecuada. Finalmente se discuten las diferentes modalidades de tratamiento

ABSTRACT

Se presenta una serie de 50 pacientes con cáncer de laringe con estudios diagnósticos preterapéuticos por TC (n=50) y laringoscopia directa (n=42). En 48/50 casos se dispuso de confirmación anatomopatológica, mientras en 2/50 casos se efectuaron biopsias múltiples. La distribución por estadios resultó: I=5; II=10; III=8 y IV=27 casos. En la estadificación de extensión tumoral "T", la laringoscopia directa cubrió un índice de aciertos diagnósticos de 78,6 por ciento, la TC del 80 por ciento. La estadificación conjunta por complementación de ambos métodos eleva sensiblemente el índice al 92 por ciento. En la estadificación de adenopatías metastásicas regionales la TC obtuvo un índice de diagnóstico correcto del 86 por ciento (43/50 casos). En cuanto a la sensibilidad de los métodos para las diversas estructuras laríngeas, la laringoscopia directa mostró altos índices en bandas ventriculares (91%), cuerdas vocales (89%), repliegues aritenoepiglóticos (89%) y comisura interior (82%), con un valor relativamente bajo para subglotis (71%). Por su parte la TC obtuvo valores similares para bandas ventriculares (88%) y repliegues aritenoepiglóticos (91%), con menor eficacia en cuerdas vocales (81%) y comisura anterior (73%). Se destacan los roles complementarios de ambos métodos analizando factores de error y su influencia en la elección terapéutica, permitiendo establecer aquellos casos posibles de beneficiarse con cirugía conservadora de la voz

ABSTRACT

Se presenta la experiencia del autor en 68 casos de carcinomas laríngeos tratados quirúrgicamente, en 20 de los cuales se realizaron laringectomías parciales. Se discuten las bases embriológicas, anatómicas, fisiológicas y clínicas así como los métodos de evaluación utilizados para determinar los candidatos a cirugía funcional de la laringe. Los resultados obtenidos comprenden un 80% de erradicación del tumor, que alcanza el 93% en casos de carcinomas glóticos. Las complicaciones de consecuencias de esta serie representan sólo un 5%. La fijación de una cuerda vocal, así como el uso de radioterapia previa condicionan seriamente el uso de estas intervenciones.

ABSTRACT

Serial sections of 34 transglottic cancer specimens were studied for supplementing the UICC Tumor Classification System. Transglottic cancer is characterized by invasion of the paraglottic space. It invaded the laryngeal framework in a 53 percent of cases [18 out of 34], comparing clinical with pathological classification, we had understaging in 64.7% [22/34] cases. Invasion of the laryngeal framework was closely related to size of the primary lesion, cervical node metastasis appeared to be related to size of the tumor. Follow-up data showed that there was a relationship between the size of the lesion and prognosis. We propose that transglottic cancer is not an advanced lesion of supraglottic or glottic cancer, it is a special type of laryngeal cancer
