ABC/GCB labels of our 69 DLBCLs on the basis of the gene expression signature. (A) Heatmap shows assignment of labels to our 69 cases of DLBCLs on the basis of the gene expression signature with the use of Bayesian predictor with cutoff value of 0.9. (B) Kaplan-Meier estimates of overall survival and PFS according to case labels assigned on the basis of the gene expression signature show that patients with GCB DLBCL have higher probability of OS (left) and PFS (right) than patients with ABC DLBCL.
