Résumé : There have been important advances in the treatment of locally advanced squamous cell carcinoma of the head and neck (SCCHN). For patients with unresectable disease, the use of platinum-based chemoradiotherapy has improved the 3-year survival rate from 15-20% to 35-50%. The results of recent studies involving sequential therapy of induction chemotherapy including taxanes and chemoradiation have shown encouraging survival rates, near to 60-70%. Moreover, progress in the understanding of the molecular changes that lead to the development of these tumors is bringing novel diagnostic and therapeutic approaches into clinical practice, promising new hope to patients with a devastating and lethal disease.
