Introduction:
Lung cancer is one of the leading causes of cancer-related mortality. There are many exogenic and endogenic factors associated with the development of lung cancer. One of these factors is trace elements. Under- or overabundance of trace elements can disrupt cellular functions and lead to the formation of cancer. In this study we conducted elemental analysis of lung cancer tissue and normal lung tissue to investigate the role of tissue trace element concentrations in lung cancer.
Materials And Methods:
Elemental analysis was performed on 30 lung cancer tissue samples and a control group of 15 normal lung tissue samples, all taken from patients diagnosed, treated and followed at our hospital between 2005 and 2010. The solubilized tissue samples were analyzed for the presence of 19 elements using inductively coupled plasma-optical emission spectroscopy (ICP-OES). Total element amounts in the tissue were calculated.
Result:
Concentrations of magnesium, potassium, zinc, manganese, lead, boron, chromium and phosphorus were significantly higher in the patient group compared to the control group. Deceased patients had significantly lower phosphorus concentrations and significantly higher lead concentrations than the other patients.
Conclusions:
Elevated levels of magnesium, potassium, zinc, manganese, lead, boron, chromium and phosphorus in lung cancer tissue indicate that these elements may play a role in the development of lung cancer. The results of our evaluation of the association between trace elements and lung cancer suggest that, together with other factors, low phosphorus concentration and high lead concentration in tumor tissue may influence disease course.
