G3BP1 and posterior cortical atrophy: Interestingly, when we evaluated the probability of metastasis-free survival of primary 1,626 PCa patients stratified based on low or high G3BP1 group using genome-wide microarray gene expression data from a clinically available prognostic assay (Decipher; GenomeDx Biosciences, Vancouver, BC, Canada),9 we found that patients with ‘‘high’’ G3BP1 expression showed a lesser chance of metastasis-free survival.
