By univariate Kaplan–Meier survival curve and log-rank test, Age (P < 0,0001), Primary site (P < 0.0001), Tumor histology type (P < 0.0001), Tumor size (P < 0.0001), Extension (P < 0.0001), Laterality (P = 0.01), Surgery (P < 0.0001), Radiation (P < 0.0001), Chemotherapy (P < 0.0001) and Tumor number (P < 0.0001) are risk factors for the prognosis of patients with high-grade astrocytoma. The results of the established K-M survival curves and log-rank tests showed that Age ≥ 80 years, Primary site at brainstem, Astrocytoma, NOS, Tumor size < 60 mm, deeper Extension, Bilateral, no Surgery, no Radiotherapy or Chemotherapy and Tumor number > 1 were all associated with poorer survival time in patients (Fig. Kaplan Meier survival curve in high-grade astrocytoma patients.
