Levels of serum trace elements in renal cell carcinoma cases.

Trace elements which are essential components of biological structures may also be toxic when present at levels above the amounts required for biological function. In our study, trace element levels were measured with furnace atomic absorption spectrophotometry in 33 newly diagnosed renal cell carcinoma cases (preoperative) and 32 healthy controls. When compared with the control group, it was found that the levels of cadmium (Cd), lead (Pb) were higher and the levels of zinc (Zn), iron (Fe) and manganese (Mn) were lower in the patient group. These changes may be important in the formation of renal cell carcinoma, a question which should be explored with postoperative comparative studies.
