Tumor marker (CEA>5, p = 0.03), and nodes involvement of {#11 (p = 0.01), and #12 (p < 0.01)} were revealed to be independent negative prognostic factors affecting OS, and other variables such as sex (p = 0.78), age (>70, p = 0.84), smoking habits (BI > 400, p = 0.34), tumor size (>30 mm, p = 0.30), pathology [adenocarcinoma (AD) or non-AD, p = 0.27], differentiation index (poorly or not, p = 0.54), and node involvent of #10 (p = 0.55) were not. Here, CEACAM5 is linked to Alzheimer disease.
