ABSTRACT

Background:

In Brazil, 5870 new cases of malignant central nervous system tumors (MCNST) were estimated for men and 5220 for women for each year of the 2020-2022 triennium. The objective of this study was to analyze incidence rate trends and compare demographic characteristics of new MCNST cases according to tumor topographies in Brazil from 2000 to 2015.

Methods:

This study comprises an analytical cross-sectional assessment of secondary databases extracted from the Brazilian National Cancer Institute (INCA) website. Data comprised new neoplasm cases of meninges (C70), brain (C71), spinal cord, cranial nerves, and other central nervous system parts (C72) retrieved from 23 population-based cancer registries. A descriptive analysis was performed. Crude and age-adjusted incidence rates were calculated. Linear trends were calculated using a linear least squares regression for adjusted incidence rates versus time.

Results:

A total of 24 986 new MCNST cases were recorded. The main topography was the brain (91.5%). Except for meninges tumors, where 62.4% of the cases were observed in women, MCNST cases were more frequent among men concerning the other evaluated topographies. All 3 topographies occurred predominantly in adult patients aged from 40- to 64-year-old. Between 2000 and 2015, incidence rates ranged from 5.12 to 4.95 (a 1.4% increase of per year; 95% CI -4.0 to 6.8; P = .584) in men and from 4.35 to 3.61 (a 3.1% increase per year; 95% CI -1.7 to 8.0; P = .189).

Conclusions:

The most frequent topography was the brain. Incidence rates of MCNST remained relatively stable over time in both sexes.
