چکیده انگلیسی:
Introduction: Lung cancer is the most common cause of cancer-related death among males and females. The diagnosis of lung cancer is of great importance for clinical considerations and follow-up treatment. This study aimed to examine the expression of CEA, LUNX, and CK19 biomarkers in the cancerous and healthy tissues of patients suffering from NSCLC. Methods: In this study, 30 patients with NSCLCs referring to Masih Daneshvari Hospital in Tehran were voluntarily selected prior to taking any treatment. A tissue sample from the center and a sample of healthy tissues close to the cancerous masses were prepared by a specialist in the bronchoscopy sector and tested using real-time RT-PCR. Results: Positive CEA mRNA was observed in cancerous tissues in the center of tumors of 25 out of 30 cases. In the healthy tissue group, the same was found in 10 out of 30 cases (P<0.001). The markers CK19 and LUNX mRNAs showed to be positive in cancerous samples in the center of tumors of 15 and 22 out of 30 cases, and in the healthy tissue group, the expression was observed in 5 and 4 out of 30 cases, respectively(P<0.001). Conclusion: This study confirms that the aformentioed markers are the ones with a relatively appropriate sensitivity and specificity for the diagnosis of lung cancer.
