Abstract
Introduction: Non?small cell lung cancer (NSCLC) is the leading cause of mortality globally. Early imaging detection modalities are associated with high false?positive rates and radiation exposure. A non?invasive biomarker can serve as an improvised method for early detection. MicroRNAs can serve as a potential non?invasive biomarker as they are stable in circulation, tissue or biological process?specific, easy to detect, cost?effective, and not associated with radiation hazards. This study validates circulating microRNA in NSCLC of the Indian population and studies its correlation with clinicopathological parameters. Materials and Methods: Circulating microRNA (?miR?193b, miR?301a, miR?7, and miR?25) was evaluated in 101 cases of tissue?proven NSCLC and 28 controls in serum samples. Results: There were 67 male and 34 female patients (Male: Female = 1.97:1). The age range was 25 to 86 years with a median age of 60 years. There was a significant upregulation in the expression of miR?193b in the NSCLC group as compared to controls (P = 0.034). MiR?7 was also upregulated while miR?25 and miR?301a were downregulated in NSCLC as compared to controls; however, a level of significance was not achieved. ROC curve analysis for miR?193b showed an AUC of 0.636 (95% CI, 0.522?0.750; P-value = 0.036) between NSCLC cases and controls. Conclusion: The present study showed variable expression of the above?studied miRNAs. MiR?193b showed a significant upregulation in cancer patients; however, the other three miRNAs were not conclusive. This suggests that profiling of microRNA in each population is essential to search for a valid non?invasive biomarker in that population.
