SEOM clinical guidelines for the treatment of nasopharyngeal carcinoma.

Nasopharyngeal carcinoma is an unusual tumour in Spain. It has differences in epidemiology, histology, clinical behaviour, treatment and prognosis from those of other head and neck neoplasms, which justifies separate analysis. It is a neoplasm with a high possibility of cure with a combined treatment if even it is diagnosed in an advanced locoregional stage (stage III or IV, without metastasis). The multidisciplinary team, bringing together all professionals who specialize in the diagnosis and treatment of these tumors make the decision to establish the best sequence of individualized diagnosis, staging and treatment for each patient. This guide gives recommendations for diagnosis, staging and treatment for nasopharyngeal carcinoma. The treatment recommendations are summarized as local disease, locally advance and recurrent and metastatic disease.
