title: [Clinical descriptive study of 40 patients with carcinoma of the nasopharynx in advanced stage in an area of low epidemiological risk].
abstract: The nasopharyngeal carcinoma in Spain, low risk geographical area, is a rare tumor. This is the cause why there few papers about it in our country. We have carried out a muestral descriptive statistical study. We have selected among all the patients diagnosed of nasopharyngeal carcinoma a big group who, have been treated with induction chemotherapy followed by radiotherapy with or without surgery, they presented very complete clinical histories in the Departments of E.N.T., Oncology and Radiotherapy that allowed us to compare all the picked up data and this increased, without doubt, the reliability of them. The results obtained in the different examined variables of our patients are the same that those we found in literature. The nasopharyngeal carcinoma is a tumor that usually affects young patients, of both sexes, without previous consumption of alcohol and tobacco and they are diagnosed in advanced stages. The rhinologic symptoms are the most frequent ones but the cervical nodes are the usual cause for consulting a doctor with a long diagnostic interval. There is a prevalence in the undifferentiated tumors showed by histology.
