Objective To explore the expression changes of KIAA1199 and Linc00673 genes in non-small cell lung cancer patients before and after chemotherapy,and to further evaluate the potential value of these two genes as molecular markers in predicting chemotherapy efficacy.Methods A total of 58 patients with stage Ⅲ-ⅣNSCLC admitted to the Third Hospital of Shijiazhuang and Fengfeng General Hospital of North China Medical Health Group from August 2019 to August 2021 were selected.Peripheral blood PBMCs were collected from patients 2 days before treatment and after two cycles of treatment to detect the expression levels of KIAA1199 and Linc00673 genes.The chemotherapy efficacy of patients was statistically analyzed,and the value of KIAA1199 and Linc00673 genes as molecular markers in predicting chemotherapy efficacy was assessed using ROC curve analysis.Results After 2 cycles of chemotherapy,20 out of 58 patients showed disease progression,accounting for 34.48%.qPCR results showed no statistically significant difference in the expression levels of KIAA1199 and Linc00673 genes between progressed and non-progressed patients before treatment(P>0.05).After treatment,the expression levels of KIAA1199 and Linc00673 genes were significantly lower in non-progressed patients compared to progressed patients(P<0.01).ROC curve analysis showed that the AUC of combined detection was significantly higher than that of KIAA1199 gene and Linc00673 gene alone(Z=3.054,5.178,P<0.05).Conclusion In NSCLC patients undergoing chemotherapy,the expression of KIAA1199 and Linc00673 genes shows significant differences based on therapeutic efficacy,with KIAA1199 being more suitable as a biomarker for predicting chemotherapy efficacy.
