Characteristics and prognostic factors of age-stratified high-grade intracranial glioma patients: A population-based analysis

摘要

We evaluated characteristics and different prognostic factors for survival in age-stratified high-grade glioma in a U.S. cohort. Eligible patients were identified in the Surveillance, Epidemiology, and End Results (SEER) registries and stratified into 3 age groups: 20–39 years old (1,043 patients), 40–59 years old (4,503 patients), and 60 years old (5,045 patients). Overall and cancer-related survival data were obtained. Cox models were built to analyze the outcomes and risk factors. It showed that race was a prognostic factor for survival in patients 40 to 59 years old and in patients ≥60 years old. Partial resection was associated with lower overall survival and cause-specific survival in all age groups (overall survival: 20–39 yr: HR = 6.41; 40–59 yr: HR = 4.84; 60 yr: HR = 5.06; cause-specific survival: 20–39 yr: HR = 5.87; 40–59 yr: HR = 4.01; 60 yr: HR = 3.36). The study highlights that, while some prognostic factors are universal, others are age-dependent. The effectiveness of treatment approaches differs for patients in different age groups. Results of this study may help to develop personalized treatment protocols for glioma patients of different ages.
