Radioclinical and anatomopathological correlation in larynx cancer

A Chaouki

Laryngeal carcinomas account for about 2.4% of all malignant tumors and whose squamous cell carcinoma is the most frequent histological type (95%). Direct laryngoscopy and biopsy are the gold standard for the diagnosis of laryngeal cancer, but multiple imaging modalities exist and some are under development including spiral computed tomography (CT) and more recently multi-detector computed tomography which allowed neoplasm identification at an early stage. The endoscopy-computed tomography pair allows exploration of the anatomic zones (the para-glottic space, the subglottis, the cartilages and the hyo-thyro-epiglottic space…) whose impact modifies the therapeutic management (partial laryngectomy, total laryngectomy or even a surgical contraindication). The aim of this study is to compare the reliability of CT and endoscopy in evaluating the initial loco regional extension of laryngeal cancer by referring to histologic data.
