Özet

Larynx cancer is one of the most frequently seen cancer type between head and neck cancers. Even thought the effective mechanisms in cancer development are not well describe, it is accepted that the effect of some elements carry out important etiology in carcinogenesis. In present study we investigated some trace element concentrations in tumor tissue (n=30) and free-adjacent tissue samples (n=30) of larynx cancer patients. All of the patients were smokers about 20 years. Trace elements were determined by atomic absorption spectrophotometer (Shimadzu AA-680). When Cu, Cd and Zn concentrations of cancer tissue and free-adjacent tissue compared, Cu and Cd levels were found to be higher (p<0,001); but Zn level was lower in cancer tissue (p<0,05) than free-adjacent tissue and no statistically difference was found from Pb point of wiev (p>0,05). Malign tumors may be increase by smoking about long years. Accumulation of high metals in the organism may be change the structure of cells.
