VDR and cancer: In a cox regression multivariate analysis of the present cohort with established prognostic markers, cytoplasmic VDR expression proved to be a statistically independent prognostic factor (HR 2.218, p = 0.025), as well as cancer grading (HR 1.604, p < 0.001), FIGO stage (HR 1.947, p < 0.001) and patient’s age (HR 1.628, p = 0.019) (Table 3) were proved independent factors.
