Abstract

L'invention concerne un outil non invasif pour effectuer le diagnostic de maladies de la peau, destiné à être utilisé en tant que dispositif clinique auxiliaire. L'étude sur laquelle est fondée cette invention avait pour but de déterminer si la spectroscopie dans le visible/infrarouge proche peut être exploité pour la caractérisation non invasive de maladies de la peau. Des spectres in vivo dans le visible et infrarouge proche (400-2500 nm) de tumeurs de la peau (kératoses séniles, carcinomes basocellulaires, naevus mélanocytaires banals communs acquis, naevus mélanocytaires dysplastiques, lentigines actiniques et kératoses séborrhéiques) ont été obtenus au moyen d'une sonde à fibre optique placée sur la peau. On a fait appel à des tests t jumelés, à une analyse de variance et à une analyse discriminatoire de mesures répétées pour déterminer s'il y avait des différences spectrales significatives et si les spectres pouvaient être classés selon le type de lésion. Les tests t jumelés ont montré des différences significatives (p<0,05) entre une peau normale et une peau présentant des lésions, dans plusieurs zones du spectre visible/infrarouge proche. En outre, des différences significatives ont été trouvées entre les groupes de lésions, par analyse de variance. L'analyse discriminatoire linéaire a permis de différencier des spectres résultant de lésions bénignes, en comparaison avec des lésions pré-malignes ou malignes. La spectroscopie dans le visible/infrarouge rouge constitue une technique non invasive prometteuse pour le diagnostic de maladies de la peau.
