Additionally, we evaluated the potentiality of employing these factors as a biomarker tool for the diagnosis and assessment of uterine fibroid progression.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>This study involved the participation of 55 women with leiomyomas and 50 healthy women. We utilized commercial ELISA kits to measure the levels of total VitD and DBP in their serum. Additionally, we calculated the levels of free VitD and the ratio of VitD to DBP. Moreover, we determined the number, size, and location of the leiomyomas in the patients.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>There were no significant differences in the levels of total VitD between the groups. However, patients had significantly lower levels of free VitD and higher levels of DBP compared to the control group. The size of the largest leiomyomas showed a negative relationship with free VitD and a positive relationship with DBP. Receiver operating characteristic analyses, showed that the cut\u2010off value for free VitD was 4.47\u2009pg\/mL, with a sensitivity of 75.6% and a specificity of 74.4%. The cut\u2010off value for DBP was 256.2\u2009\u03bcg\/mL, with a sensitivity of 86% and a specificity of 70.3%.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Free VitD and DBP potentially contribute to the development of leiomyomas and are linked to the size of these tumors.
