ABSTRACT

BACKGROUND: The presence of intratumoral lymphatic vessels (ILVs) and the expression of vascular endothelial growth factor-C (VEGF-C) in tumour cells have been studied as markers of lymphangiogenesis in order to evaluate their role in metastatic dissemination in laryngopharyngeal squamous cell carcinoma. METHODS: A retrospective study was performed in 76 patients of N0 laryngopharyngeal carcinoma. with variable tumour size (T1-T4), histological grade, and location (supraglottic, glottic and hypopharyngeal). The presence of ILVs, as revealed by the expression of PA2.26 antigen and VEGF-C expression, were determined by immunohistochemistry (IHC). Low-grade and high-grade lymphangiogenesis were defined by qualitative and quantitative criteria. RESULTS: Multivariate analysis revealed low-grade ILV and VEGF-C expression to be associated respectively with 30.3- and 16.2-fold higher probabilities of cervical lymph node relapse (P = 0.005 and P = 0.032) and with 16.2- and 8.44-fold shorter disease-free survival (P = 0.009 and P = 0.045). CONCLUSIONS: Low-grade ILV and VEGF-C expression are independent predictive factors of cervical lymph node relapse and shortening of time to relapse in N0 laryngopharyngeal carcinoma.

ABSTRACT

Objetivo: Las perforaciones de la hipofaringe y del esófagocervical son hechos graves e infrecuentes que, incluso,pueden poner en peligro la vida del paciente. El otorrinolaringólogo,en función del área anatómica en que desarrollasus funciones, debe conocer bien esta patología.Material y métodos: Revisamos diez casos de perforacionesintraluminales de la hipofaringe o el esófago cervical,tratados en nuestro servicio entre los años 1.999 y 2003.Resultados: Los cuerpos extraños fueron la causa principalde perforación. En cuatro casos el tratamiento fuequirúrgico y en los seis restantes empleamos un tratamientoconservador. En algunos casos la morbilidad fueimportante pero no hubo mortalidad.Conclusiones: El tratamiento de las perforaciones a estenivel debe ser individualizado y multidisciplinario. El diagnósticoprecoz es un factor pronóstico importante. Losavances en la terapéutica antibiótica y nutricional, juntocon el cumplimiento de las indicaciones, permiten quecada vez podamos utilizar con mayor frecuencia y máséxito los tratamientos conservadores


Background:Perforations of the hypopharynx and the cervicaloesophagus are severe infrequent situations whichmay even be life-threatening for patients. Theotorhinolaryngologist must be aware of this situation.Material and methods: We review ten cases ofintraluminal perforations of the hypopharynx or cervicaloesophagus, treated at our department between 1999and 2003.Results: Foreign bodies were the main cause ofperforation. In four cases, the treatment was surgical,and in the other six cases, conservative treatment wasapplied. In some cases, the morbidity was considerablebut there were no mortalities.Conclusions: The treatment of perforations at this level mustbe individualized and multidisciplinary. The early diagnosisof these perforations is an important factor for prognosis.Advances in antibiotic and nutritional therapies andobservance of the indications, made possible a more frequentand successfully use of a conservative therapeutic approach

ABSTRACT

Los hemangiomas cavernosos laríngeos son lesiones benignas y poco frecuentes, cuya presentación es todavía más rara en la edad adulta. En éstos, aparecen fundamentalmente en la supraglotis y la práctica totalidad de los pacientes afectos son varones. La sintomatología es escasa y de largo tiempo de evolución, predominando la disfonía. Su histología es característica y permite diferenciarlos de otras lesiones de aspecto clínico similar. El método de tratamiento de elección para la mayoría de los autores es la resección quirúrgica. La hemorragia no siempre está presente, pero hay que tenerla en cuenta. Presentamos el caso de un gran hemangioma cavernoso de presentación supraglótica en un varón de 35 años. La resección se realizó por vía endoscópica, previa traqueotomía. No hubo problemas hemorrágicos (AU)
