However, despite the significant correlation of changes in the vimentin expression with the changes in the CSC proportion after irradiation at a TD of 10 Gy (p = 0.008), only a tendency to a greater increase in the expression of vimentin was found in patients with partial tumor regression compared to that with complete regression (p = 0.16 and p = 0.17 in univariate and multivariate analyses, respectively). This evidence concerns the gene VIM and neoplasm.
