        Objective: The objective of the study is to report epidemiological characteristics and prognostic factors of patients with adult-type gliomas treated in the neurosurgery department of the National Medical Center of Bajío, as well as to evaluate, for the 1 time in Mexican patients, surface regularity (SR). Methods: Epidemiological and clinical features were statistically compared with international references. Survival was estimated using the Kaplan-Meier method. Kaplan-Meier curves were compared with the log-rank test. SR was obtained by segmenting magnetic resonance imaging. Results: Median age of patients with glioblastomas was less than that of patients in the United States (p = 0.021). The administration of radiotherapy (RT) and temozolomide (TMZ) prolonged survival (median gain of 35 months). Median SR was 0.6006 and was close to being statistically lower than the value reported in a large cohort (p = 0.09). Conclusions: Glioblastomas were diagnosed at younger ages and appeared to be more aggressive. The administration of RT and TMZ prolonged substantially survival.
        Objetivo: Reportar las características epidemiológicas y los factores pronósticos de los pacientes con gliomas de tipo adulto tratados en el servicio de neurocirugía del Centro Médico Nacional del Bajío, así como evaluar, por primera vez en pacientes mexicanos, la regularidad de la superficie. Métodos: Se compararon estadísticamente las características epidemiológicas y clínicas con referencias internacionales. La supervivencia se estimó mediante el método de Kaplan-Meier. Las curvas de KaplanMeier se compararon con la prueba de log-rank. La regularidad de la superficie se obtuvo mediante la segmentación de la resonancia magnética. Resultados: La mediana de edad de los pacientes con glioblastomas fue menor que la de los pacientes en Estados Unidos (p = 0.021). La administración de radioterapia y temozolomida prolongó la supervivencia (ganancia mediana de 35 meses). La regularidad de la superficie mediana fue de 0.6006 y estuvo cerca de ser estadísticamente menor que el valor reportado en una cohorte grande (p = 0.09). Conclusiones: Los glioblastomas se diagnosticaron a edades más jóvenes y parecieron ser más agresivos. La administración de radioterapia y temozolomida prolongó sustancialmente la supervivencia.
