Total Sialic Acid, Antioxidant Enzyme Activities, Trace Elements, and Vitamin Status Before and After Surgery in Women with Uterine Myoma and Endometrial Cancer

The objective of present study was to examine endometrial tissue Be, As, Cr, Mo, Sr, Ti, Tl, Cu, Co, Se, Zn, Mn, Fe, Cd, Pb, Mg, P, erythrocytes CAT, SOD, GSH-Px, GSH, MDA, serum retinol, cholecalciferol, phylloquinone, TSA, LSA, TOS, and TAS status and to evaluate the relationships between the variables. The study had 110 participants; of these, 50 were women with uterine myoma (UM), 10 were women with endometrial cancer (EC), and 50 were healthy female subjects. In the study, vitamin analyses by HPLC and element analyses were determined using ICP-OES method. It was observed that EC group was significantly lower than healthy group in terms of levels of cholecalciferol ( p < 0.05), phylloquinone ( p < 0.01), GSH ( p < 0.05), Fe ( p < 0.05), and had a significant rise in Mg/Fe ( p < 0.01) and Zn/Fe ( p < 0.05) in preoperative period. UM group had significantly lower retinol ( p < 0.05), phylloquinone ( p < 0.001), GSH-Px ( p < 0.01), GSH ( p < 0.01), Cr ( p < 0.01), Cu ( p < 0.05), Mg ( p < 0.01), and Zn ( p < 0.01) levels than control group in preoperative period and significantly higher levels of MDA ( p < 0.01), TSA ( p < 0.01), and LSA ( p < 0.01) than control group. It was found that significant associations were observed between Cu–CA 15–3 ( r = 0.558, p = 0.016), Mn–CA 15–3 ( r = 0.511, p = 0.030), P–CA 15–3( r = − 0.502, p = 0.034) and with UM, also between GSH–CA-125 ( r = − 0.825, p = 0.022) and with EC group. The results of correlation analysis observed that concentrations of Cu, Mn, P, and GSH together with CA 15–3 and CA-125 levels might be important for monitoring patients with UM and EC before surgery.
