[Clinical descriptive study of 40 patients with carcinoma of the nasopharynx in advanced stage in an area of low epidemiological risk]. / Estudio clínico descriptivo de 40 pacientes con carcinoma de nasofaringe en estadio avanzado en un área de bajo riesgo epidemiológico.

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.

[Morphometric and stereologic nuclear values obtained from the study of a population suffering from nasopharyngeal carcinoma]. / Valores morfométricos y estereológicos nucleares obtenidos en el estudio de una población con carcinoma de nasofaringe.

Computer nuclear morphometry and stereology are attractive methods because its objectivity and cheapness allowing histologic diagnosis when identifying minimal variations respectively the normality and also detect negligible disparities between anormal cells which could escape to the assessment of the pathologist. We present the data gained from several morphogenic and stereologic parameters resulting of measurements of tumoral cells procured from 40 patients with nasopharyngeal carcinomata. Middle values have been: nuclear area 27.70 microns 2; nuclear perimeter 20.80 microns; nuclear factor of form 0.81 microns; nuclear outline index 4.01; nuclear orientation angle 87.29 degrees; nuclear ellipsiticity 704.14; nuclear regularity 61.83; middle lineal length 4.30, middle linear distance 107.94; and nuclear volume 118.80 microns 3. Our series is the largest studied till now of all found in the literature. Comparison our data with those of previous publications.
