The results of the multivariate analysis (Cox regression analysis model) of OS that can be the independent prognostic factors or OS were as follows: tumor grade (HR 2.029; 95% CI 0.5536 to 9.059; p = 0.0213), IL-13Rα2 (HR 2.382; 95% CI 1.056 to 5.380; p = 0.0010), Ki-67 (HR 3.439; 95% CI 1.098 to 13.44; p = 0.0079) and P53 (HR 1.317; 95% CI 0.6046 to 3.052; p = 0.0113). The gene discussed is MKI67; the disease is neoplasm.
