Table 2.

Overview of obtained results (shown in Figure 1) summarizing the histopathological differentiation, VitD serum levels, and VDR/Ki67 expression in the cancer patients and healthy controls. VDR expression in the cancer tissue was inversely correlated with the VitD serum levels. High VDR expression occurred in poorly differentiated, highly proliferative tumor tissues.

Differentiation	VitD ng/mL	VDR		Ki67 (IHC)
		IF	IHC
Poor	4.1 ± 0.5	High	High	High
Moderate	7.3 ± 4.3	Med	Med	Med
Well	13.2 ± 3.4	Low	Low	Low
Control	29.12 ± 4.7	M = Low, F = High	M = Low, F = High	Low
