Multivariate Cox regression analysis indicated that tumor diameter, TNM stage, Gal1 and NCAPG expression were independent prognostic factors for GC (Gal1: HR, 0.072, 95% CI, 0.035–0.145, P < 0.001; NCAPG: HR, 0.185, 95% CI, 0.081–0.420, P < 0.001, Table 3). This evidence concerns the gene NCAPG and gastric cancer.
