Study of Risk Factors for Nasopharyngeal Carcinoma: About 214 Cases

Nasopharyngeal carcinoma (NPC) is a malignant tumour of the nasopharyngeal epithelium. It is very aggressive; with geographical distribution, placing Morocco in an intermediate incidence zone; and multifactorial etiology. We report here 214 cases of NPC followed within the Radiation Oncology Department of the Mohammed VI University Hospital in Marrakech, 84.58% of whom presented with at least one risk factor. The most incriminated was ENT infection (41.12%). NPC, due to its characteristics, constitutes a public health problem that requires primary prevention. Knowledge of risk factors would make it easier to raise public awareness.
