Changes in survival over time for primary brain and other CNS tumors in the United States, 2004–2017

1

In 2018, the US saw approximately 88,190 new cases of primary brain and CNS tumors, with non-malignant tumors diagnosed more frequently than malignant ones.
2

From 2001 to 2017, the 5-year relative survival rate for primary malignant brain tumors was 66.9%, with younger age groups showing better survival rates.
3

Survival rates vary significantly by age, sex, race/ethnicity, and tumor characteristics, with females generally having better outcomes than males.
4

Surgical resection extent is a positive prognostic factor for malignant brain tumors, and combined radiation and chemotherapy improve survival for glioblastoma.

This study analyzed survival data for primary brain and CNS tumors from 2004 to 2017, utilizing comprehensive data from the CDC's National Program of Cancer Registries.
