Levels of chemical element contents in thyroid as potential biomarkers for cancer diagnosis (a preliminary study)
Aim: Thyroid cancer is an internationally important health problem. The aim of this exploratory study was to evaluate whether significantchanges in the thyroid tissue levels of Al, B, Ba, Br, Ca, Cl, Cu, Fe, I, K, Li, Mg, Mn, Na, P, S, Si, Sr, V, and Zn exist in the malignantly transformed thyroid.
Methods: Thyroid tissue levels of twenty chemical elements were prospectively evaluated in 41 patients with thyroid malignant tumors and 105 healthy inhabitants. Measurements were performed using a combination of non-destructive and destructive methods: instrumental neutron activation analysis and inductively coupled plasma atomic emission spectrometry, respectively. Tissue samples were divided into two portions. One was used for morphological study while the other was intended for trace element analysis.
Results: It was found that contents of Al, B, Br, Ca, Cl, Cu, K, Mg, Mn, Na, P, S, and Si were significantly higher (approximately 3.2, 4.6, 9.3, 1.8, 2.3, 3.6, 1.6, 1.6, 1.6, 1.2, 2.5, 1.1, and 2.8 times, respectively) while content of I lower (nearly 26 times) in cancerous tissues than in normal tissues.
Conclusion: There are considerable changes in chemical element contents in the malignantly transformed tissue of thyroid.
