[Level of copper and zinc in plasma of patients with lung cancer].

Microelements metabolic disorders, including copper and zinc, constitute an important field of cancer studies. Efforts are undertaken to identify cancer markers. Found changes in plasma copper and zinc levels in patients with lung carcinoma may have clinical implications, and help in the diagnosis despite the fact that there are no reports in the literature confirming specificity of these two elements for lung carcinoma. Plasma copper and zinc levels were determined in blood samples of 94 patients with lung carcinoma with atomic absorption technique. The obtained results were compared with those in 20 healthy blood donors, and were analysed statistically and plotted graphically. Statistically significant differences in patient's plasma vs control group were noted.
