For the RFS, the sex (p = 0.033), CEA (p = 0.070), pN (p = 0.045), LNR (p < 0.001), tumor differentiation (p = 0.097), lymphatic invasion (p = 0.003), vascular invasion (p = 0.025), and adjuvant chemotherapy (p = 0.024) were selected for multivariate analyses. This evidence concerns the gene CEACAM5 and neoplasm.
