Incidence and survival of primary central nervous system tumors diagnosed in 4 Canadian provinces from 2010 to 2015.

ABSTRACT:

Background

The Brain Tumor Registry of Canada was established in 2016 to enhance infrastructure for surveillance and clinical research on Central Nervous System (CNS) tumors. We present information on primary CNS tumors diagnosed among residents of Canada from 2010 to 2015.

Methods

Data from 4 provincial cancer registries were analyzed representing approximately 67% of the Canadian population. Age-standardized incidence rates (ASIR) and 95% confidence intervals (CI) were calculated using the 2011 Canadian population age distribution. Net survival was estimated using the Pohar-Perme method.

Results

A total of 31 644 primary tumors were identified for an ASIR of 22.8 per 100 000 person-years. Nonmalignant tumors made up 47.1% of all classified tumors, with mixed behavio
