Alcohol drinking (P = 0.035) was determined to be a risk factor for DFS, whereas tumor invasive depth (P = 0.066, P = 0.108) and vimentin expression (P = 0.369, P = 0.900), which were significant in Kaplan-Meier analysis, were not identified as prognostic factors in the multivariate model. The gene discussed is VIM; the disease is neoplasm.
