ABSTRACT

Background: Lung cancer is among the most common cancers. Search is ongoing to find biomarkers to improve the diagnosis lung cancer techniques in early stages. In this study we evaluate the sensitivity and specificity of the MUC1 and CEA gene expressions in the peripheral blood of non-small cell lung cancer (NSCLC). Material and Methods: This study was done in Masih Daneshvari Hospital, Tehran, Iran and was case/control study that conducted on 30 NSCLC patients and 30 healthy controls. Peripheral blood was collected and total RNA was extracted then cDNA was synthesized. Sample was separately assessed by real time PCR. Results: The expression of CEA gen was positive in 24 patients indicating 80% sensitivity for this marker. The expression of CEA gen was positive in 9 controls out of 30 each. A statistically significant difference was detected between patients and healthy controls with regard to CEA mRNA expression (P < 0.001). The MUC1 gen expressed in 20 out of 30 patients, while it expressed in 3 controls. The difference in MUC1 mRNA expression was statistically significant between NSCLC patients and healthy controls (P < 0.001). Conclusion: MUC1 and CEA are molecular biomarkers with relatively favorable sensitivity for primary diagnosis of NSCLC.
