Neoplasias del sistema nervioso central e intracraneales

Objective: To describe the behavior of neoplasms presentation of the central and intracranial nervous system, in a Mexican health institution specialized in neurosurgical sufferings. Methods: A descriptive study was carried out in a sample was made up of 7768 patients with histopathological diagnosis neoplasms of central and intracranial nervous system. They were assisted at the National Institute of Neurology and Neurosurgery, from Mexico City, from 2006 to 2017. The variables studied were the incidence and year of presentation of tumors, type of tumor, sex and age of presentation. Depending on the morphological and immunohistochemical diagnosis of tumors, these were categorized in accordance with the classification of tumors by 2007 WHO Central Nervous System. Simple frequencies were obtained; the incidence reason was calculated for each category. The trend over time was analyzed with the Pearson correlation coefficient; a p≤ 0.05 was considered statistically significant. Results: The general incident rate was 70.2 x 100 biopsies-year. The most frequent tumors were neurepithelial tissue (30.8%) and meninges (27.6%), with predominance in women (p <0.05). An increase in embryonic tumors (p <0.005) was evidenced. Conclusions: A tendency was not found in the increase of tumors of the central nervous system over the period studied. However, the incidence of this type of neoplasms is high. They cause high mortality and disability in those who have them.
