Analysis of Chilean trends in mortality from malignant brain tumors
Rev. chil. neuro-psiquiatr; 44 (4), 2006
Publication year: 2006
Objective:
To analyse the Chilean trends in mortality from brain malignancies between 1985 and 1999.Methods:
We calculated mortality rates from malignant brain tumors using data obtained from death certificates available at the National Statistics Office.The following International Classification of Diseases categories were selected:
191.0 to 191.9 (ICD-9), and C71.0 to C71.9 (ICD-10). The rates were adjusted using direct standardization. Prais-Winsten methodology was used for time correlation analysis.Results:
Sex-specific rates varied from 0.9 to 1.75 per 100.000 in men and from 0.7 to 1.22 in women. The trend was toward a statistically significant increase in mortality from malignant brain tumors in both groups. The analysis by age group showed no statistically significant variation in those below 35 years old, and a statistically significant increase in those between 35 and 39 years old, and in those above 45 years old.Conclusions:
The trend in mortality from malignant brain tumors, in Chile, shows a statistically significant increase in those between 35 and 39 years old, and in those above 45 years old.
Existe controversia en el aumento de la incidencia en las tasas de tumores primarios malignos de cerebro. Este incremento podría explicarse por el crecimiento exponencial en el número de Tomografías computarizadas.
