Abstract: Objective To explore the expression and clinical significance of long non-coding RNA(lncRNA)OGFRP1 in serum exosomes of non-small cell lung cancer(NSCLC). Methods A total of 84 cases preliminarily diagnosed as NSCLC and 84 healthy controls were enrolled. The serum exosomes were extracted and identified, the RNA was extracted, and lncRNA expression was detected. The sensitivity, specificity and diagnostic accuracy of lncRNA OGFRP1 were statistically analyzed. The relationship between the lncRNA OGFRP1 expression and clinicopathological factors were analyzed. Results All cases were pathologically confirmed as NSCLC. lncRNA OGFRP1 was highly expressed in NSCLC(χ2=96.459, P<0.001). With pathological diagnosis as the gold standard, the sensitivity, specificity and accuracy of lncRNA OGFRP1 in the auxiliary diagnosis of NSCLC were 89.4%, 87.9% and 89.4%, respectively, higher than those of carcino-embryonic antigen(P<0.01). The relative expression of lncRNA OGFRP1 in serum exosomes was significantly associated with lymph node metastasis(P=0.034)and T stage(P=0.030)in NSCLC patients. Conclusion The detection of exosomal lncRNA OGFRP1 has high sensitivity, specificity and accuracy in the diagnosis of NSCLC, which can be used as a novel tumor marker for early screening, diagnosis and staging of NSCLC.
