“…To improve prognostic and predictive survival power in GBM patients, researchers [ 69 , 91 – 92 , 94 – 95 , 97 , 109 , 131 , 137 – 138 , 144 , 147 , 172 , 186 , 189 , 195 , 197 , 200 , 222 , 242 , 251 , 253 ], identified a panel of 2, 3, 4, 6,7, 8, 13, or 14 genes using mRNA expression datasets. They established a risk score model that performed well in survival prediction.…”
