CPZ and neoplasm: The univariate Cox regression analysis demonstrated that high CPZ expression (HR = 1.527), age > 65 years (HR = 1.620), stage III (HR = 2.381) and IV (HR = 3.991), and tumor microscopic residue (R1) and naked eye residue (R2) (HR = 3.445) were significantly associated with OS in STAD cases (P < 0.05) (Figure 3D).
