Analysis reveals treatment outcomes for glioblastoma patients across age, sex, and race, highlighting significant disparities.

This research aims to characterize disparities in glioblastoma survival based on demographic factors and treatment era.
Analyzed SEER data from 2000 to 2021 for glioblastoma patients
Stratified survival rates by age, sex, race, and treatment era
Calculated 12, 24, 36, 48, and 60 month survival percentages
Assessed statistical significance using confidence intervals
Survival improved with temozolomide treatment across most demographic groups
Significant survival increases observed in 20 out of 48 demographic strata
12-month survival rose from 20% to 51% in women aged 55–69
5-year survival for females aged 25–39 reached 30% post-2005, compared to 18% in males

Malik et al. (2025) studied this question.
