RESUMO
BACKGROUND: Oral premalignant lesions (OPML) are frequently extensive and multifocal leading high morbidity for patients. Although oral squamous carcinoma (OSCC) in non-smoker patients is increasing, little is known about OPML and the carcinogenesis process in these patients. The aims of the study were to insight and compare the clinicopathological and molecular characteristics of OPML of non-smoker and smoker patients from which one or multiple OSCC have developed. METHODS: Eighty-one patients showing extensive and/or multifocal OPML were included in the survey. HPV and EBV were investigated by PCR and in situ hybridization respectively. Cytogenetic studies were performed by microarray in sequential progressive 30 lesions; p53 expression was investigated by immunohistochemistry. RESULTS: The patients were 41 males and 40 females, ages ranging from 32 to 93 years (median 64); 43 (53%) were smokers. Non-smokers were more frequently female with a median age of 68, whereas smokers were men with a median age of 60 (P = 0.005). HPV and EBV were negative in all cases. The most consistent and earliest cytogenetic alterations in both non-smokers and smokers were loss of heterozygosity (LOH) and losses of locus harboring tumor suppressor genes. Progression to high-grade dysplasia and OSCC showed progressive addition of LOH, tumor suppressor losses, and oncogenic gains. CONCLUSION: Non-smoker patients are mostly elderly female and show oral carcinogenic pathways and outcomes similar to smoker patients.

En noviembre 2014 la Sociedad Española de Otorrinolaringología, la Sociedad Española de Sueño y la Sociedad Española de Cirugía Maxilofacial propusieron y avalaron la elaboración de una Guía de Práctica Clínica sobre la exploración física de la vía aérea superior en pacientes con apnea obstructiva del sueño. La Guía ha seguido de forma estricta en toda su elaboración las recomendaciones del manual de elaboración de guías de práctica clínica del Sistema Nacional de Salud 2007 y 2009 y el manual de la Scottish Intercollegiate Guidelines Network (SIGN) 2015. El documento final puede ser altamente útil para los fines que se propuso inicialmente: ser un referente para unificar las regiones que deben ser exploradas en los pacientes con síndrome de apnea-hipoapnea obstructiva del sueño, mediante qué tipo de exploración y cómo gradarla, y expresada para todos los ámbitos asistenciales a los que estos pacientes pueden acudir. Las conclusiones y recomendaciones están basadas en una revisión exhaustiva y actualizada de la bibliografía con alto nivel de evidencia, además de la experiencia y conocimientos demostrados de todos los integrantes del grupo de elaboración. Dicho grupo se constituyó pensando siempre en la transversalidad del proyecto, y, por tanto, han participado especialistas de todos los ámbitos implicados (cirugía maxilofacial, medicina de familia, neumología, neurofisiología clínica, odontología y otorrinolaringología). Con la misma idea se seleccionaron los revisores externos del texto final
In November 2014 the Spanish Society of Otolaryngology, the Spanish Sleep Society and the Spanish Society of Maxillofacial Surgery proposed and endorsed the development of a Clinical Practice Guideline on the physical examination of the upper airway in patients with obstructive sleep apnoea. The Guideline strictly followed the recommendations of the manual for the preparation of clinical practice guidelines of the National Health System 2007 and 2009 and the manual of the Scottish Intercollegiate Guidelines Network (SIGN) 2015. The final document could be highly useful for the purposes that were originally proposed: to act as a reference to unify the regions that should be explored in patients with obstructive sleep apnoea-hypopnoea syndrome, the type of examination and how to grade it, and specific to all the care areas to which these patients have access. The conclusions and recommendations are based on a thorough and up-to-date review of the literature with a high level of evidence, as well as the experience and knowledge demonstrated by all the members of the drafting group. This group was formed bearing in mind at all times the transversality of the project, and, therefore, specialists from all the involved areas participated (maxillofacial surgery, family medicine, pneumology, clinical neurophysiology, odontology and otolaryngology). The external reviewers of the final text were selected along the same lines
