Geographical variation in malignant and benign/borderline brain and CNS tumor incidence: a comparison between a high-income and a middle-income country.

ABSTRACT:

Purpose

There is large variability in reported incidence rates of primary brain/CNS tumors across the world, with mostly higher rates in higher-income countries. The aim was to compare malignant and benign brain/CNS tumor incidence between Zurich (Switzerland), a high-income country, and Georgia, a lower middle-income country.

Methods

For the period March 2009 to February 2012, we extracted the following tumors based on topography according to ICD-O3: C70.0-C72.9, and C75.1 (pituitary gland). Data were categorized into histology groups based on the WHO 2007 histological classification. Age-standardized rates per 100,000 person-years were calculated by subgroups.

Results

We included 1104 and 1476 cases of primary brain/CNS tumors for Zurich and Georgia, respectively. M
