[Trace elements in neoplasm tissues of the larynx].

Trace elements are essential for the proper functioning of the body. Changes in bioelements concentration were observed in numerous pathologic conditions. The aim of this study was evaluation of trace elements concentration in neoplasmatic tissues of the larynx. The study comprised 52 patients operated for cancer of the larynx. Levels of magnesium, zinc and copper in neoplasmatic tissues of the larynx were determined using atomic absorbtion spectrophotometry. The results were compared with the control group. Elevated levels of magnesium were observed in neoplasmatic tissues of the larynx. Zinc and copper levels were lowered in comparison with the control group. The results were statistically analysed.
