[Determination of trace elements, ceruloplasmin and blood proteins in pulmonary neoplasms].

In cancer process there have been found metabolic changes in several elements, especially in respect to copper. It has been proved that there is an alteration in the serum levels of some metals, and in their distribution in the proteins binding them. On the other hand, there exist, also, ceruloplasmin differences between patients serum and the control. Our work has been carried out to study the trace element metabolism in lung cancer, as well as chromium and zinc contents. Electrophoretic techniques have been applied to study the protein levels.
