Serum retinol level in patients with pre and malignant lesions of female genital tract.

The blood retinol level in women with genital tract malignancies and in a control group has been determined. In all groups of patients the mean serum retinol level was significantly lower than in control group. Based on these results we can postulate, that the low retinol level could predispose to the development of malignancy in female genital tract.
