Note:—HR indicates hazard ratio; STR, subtotal resection.
a
Age, CEL tumor volume, and tumor location were independently significant in multivariate analysis (overall P < 3.52e–8). Surgical resection is subtotal resection or gross total resection, available for 24 cases in the TCGA test cohort.
b
P value < .05, indicating the variable is significant.
c
Tumor location remained significant in Cox analysis performed on the restricted set of intermediate and large tumors.
