Development and internal validation of a Cox-based nomogram for predicting cancer-specific survival in central nervous system ependymoma: a population-based study

Key Points

• This research aims to develop and validate a nomogram for predicting cancer-specific survival in patients with central nervous system ependymoma.
• Developed a Cox-based nomogram using a population-based cohort.
• Conducted internal validation of the nomogram.
• Compared the nomogram's performance to conventional staging systems.
• The nomogram showed enhanced predictive accuracy for cancer-specific survival compared to traditional methods.
• It provided individualized risk stratification for patients with CNS ependymoma.
