Nomogram predicts overall survival in patients with Ewing sarcoma
A nomogram demonstrated a good ability to predict 3- and 5-year overall survival (OS) in patients with Ewing sarcoma, according to a study.
Researchers gathered demographic and clinic pathological characteristics from the Surveillance, Epidemiology, and End Results (SEER) database. A total of 578 patients were included.
Age, 7th AJCC stage, 7th AJCC T stage, 7th AJCC N stage, 7th AJCC M stage, and metastatic status to lung, liver, and bone were found to be significant factors according to univariate Cox analysis. A multivariate Cox analysis confirmed age, N stage, and bone metastasis were independent variables.
A nomogram was created using the independent variable to predict the 3- and 5-year OS. C-indexes and calibration curves closer to ideal curves showed the accurate predictive ability of this nomogram, the authors concluded.
