The invention relates to a method of predicting an outcome of a subject having a
glioma, comprising determining or receiving the result of a determination of a first
gene expression profile for each of one or more
immune defense response genes, and / or of a second
gene expression profile for each of one or more T-
Cell receptor signaling genes, and / or of a third
gene expression profile for each of one or more PDE4D7 correlated genes, said first, second, and third expression profile(s) being determined in a biological sample obtained from the subject, determining the prediction of outcome based on the first
gene expression profile(s), or on the second
gene expression profile(s), or on the third
gene expression profile(s), or on the first, second, and third gene expression profile(s), and, optionally, providing the prediction to a medical caregiver or the subject.
