Under multivariate Cox regression analysis, high CPZ expression (HR = 1.698), age > 65 years (HR = 1.800), stage III (HR = 1.866) and IV (HR = 3.658), and R1 and R2 (HR = 2.113) were independent prognostic risk factors for patients with STAD (Figure 3E), significantly affecting their prognosis. This evidence concerns the gene CPZ and gastric adenocarcinoma.
