VIM and neoplasm: A multiple regression analysis was performed to determine the dependence of the tumor regression degree on a number of possible predictors, including the proportion of vimentin-positive cells before and after irradiation at TD of 10 Gy, the change in this indicator after irradiation, disease stage (FIGO), involvement of regional lymph nodes (N+/N0), and histological type (keratinizing/non-keratinizing squamous cell CC).
