Ten of 12 transcripts that were prognostic in Gleason score 7 tumours remained prognostic in patients with Gleason 3 + 4 = 7 tumours (Table 3), and multivariable logistic regression analysis showed that combining CCNB1 or UBE2C with SRD5A2 slightly improved the predictive power of the model (Additional file 1: Table S4). Here, CCNB1 is linked to neoplasm.
