From: A long non-coding RNA signature to improve prognosis prediction of gastric cancer
Receiver operating characteristic(ROC) analysis of the sensitivity and specificity of the disease free survival (DFS) prediction by the 24-lncRNA risk score, AJCC stage, lymph node ratio (LNR) and postoperative chemotherapy in GSE62254 set patients with known chemotherapy information (N = 202). P values were from the comparisons of the area under the ROC (AUROC) of 24-lncRNA risk score versus those of AJCC stage, 24-lncRNA risk score combined with AJCC stage, LNR and postoperative chemotherapy, respectively. As can be seen, the 24-lncRNA risk score combined with AJCC stage showed a better prediction of DFS than AJCC stage (P = 0.0002). The predictive ability of risk score was equivalent to AJCC stage alone (P = 0.1861), but better than both LNR (P = 0.0297) and postoperative chemotherapy (P < 0.0001)
