In the multivariate analysis, all four factors were independent predictors of PFS: GALNT14-rs62139523 “A/G” genotype (p = 0.006), larger tumor diameter (p = 0.003), lower T stage (pT1 to pT3) (p = 0.004), and lower circulating CEA levels (p < 0.001). This evidence concerns the gene GALNT14 and neoplasm.
