Receiver operating characteristic (ROC) curves for the tumor size, tumor stage, lymph node metastasis, and co-expression of OPN and CD204 were used to predict overall gastric cancer survival. The area under the ROC curve for tumor size was 0.624 (95% CI, 0.540-0.709), tumor stage was 0.710 (95% CI, 0.630-0.789), lymph node metastasis was 0.663 (95% CI, 0.581-0.745), and co-expression of OPN and CD204 was 0.637 (95% CI, 0.554-0.720). These parameters were significantly associated with overall survival (p = 0.005, 0.000, 0.000, and 0.002).
