Abstract

Sinonasal carcinomas are rare tumours with an unfavourable prognosis whose management is difficult and complex, leading to high morbidity and mortality despite improvements in the field of surgery and radiotherapy. An elevated number of these tumours can be attributed to occupational exposure. In comparison with other head and neck malignancies, studies of molecular changes in these tumours are infrequent. This review was focused on findings about the epidemiology and molecular and phenotypic characterisation of sinonasal carcinomas, which can potentially be useful for diagnosis and treatment. The increasing knowledge about the molecular biology that underlies their carcinogenesis may help to identify precursor lesions, prognostic markers and markers that predict chemoradiotherapy response and, finally, to identify potential molecular targets that will expand treatment options.

Resumen

Los carcinomas nasosinusales son tumores infrecuentes con mal pronóstico y cuyo manejo es difícil y complejo, conllevando una elevada morbimortalidad a pesar de tratamientos quirúrgicos agresivos y administración de radio y quimioterapia. Son tumores frecuentemente relacionados con exposición profesional a carcinógenos. A diferencia de otros tumores de cabeza y cuello los estudios acerca de los cambios genético-moleculares de estos tumores son escasos. Esta revisión se centra en los hallazgos acerca de la epidemiología y la caracterización molecular y fenotípica de los carcinomas nasosinusales, y sus posibles implicaciones en el diagnóstico y tratamiento de los mismos. El progresivo conocimiento acerca de la biología molecular que subyace a su oncogénesis ayudaría a identificar lesiones precursoras, marcadores pronósticos y de respuesta a quimiorradioterapia e identificar potenciales dianas moleculares que permitan ampliar las opciones terapéuticas.
