ABSTRACT
Endometrial cancer is one of the most commonly diagnosed cancers in women. The search for factors that contribute to the development of cancer cells in reproductive organs should involve the detection of xenoestrogens, in particular zearalenone (ZEA) and its metabolites. Xenoestrogens are endocrine disruptors-ZEA and its metabolites are structurally similar to estrogens (macrocyclic lactone ring) and show high affinity for estrogen receptors. This study proposes a new method for the preparation of samples of human tissues with endometrial cancer by the use of the QuEChERS technique. Analytical parameters such as centrifugation temperature, extraction solvent, and adsorbents were modified to obtain satisfactory recovery for ZEA (R = 82.6%, RSD = 2.9%) and one of its metabolites, α-zearalenol (R = 50.1%, RSD = 3.2%). High-performance liquid chromatography (HPLC) with fluorescence detection and tandem mass spectrometry (LC-QTOF-MS) were used for the identification and quantitative determination of the analyzed compounds. The developed procedure was applied for analyses of human tissues with endometrial cancer. The presence of α-zearalenol was detected in 47 out of the 61 examined tissue samples. Graphical Abstract Methodology for isolation and identification of zearalenone and its major metabolites.
