NCAM1 and adenocarcinoma: In the multivariate analysis, lymph nodes metastasis (HR 8.380 95%CI 1.096–64.094 P = 0.041), vascular invasion (HR 9.923 95%CI 1.298–75.864 P = 0.027), grade of the adenocarcinoma component (HR 6.331 95%CI 2.046–19.587 P = 0.001), and CD56 positivity (HR 0.318 95%CI 0.112–0.906 P = 0.032) were independent prognostic predictor of DFS (Table 2).
