Methods A total of 70 patients with advanced NON-small cell lung cancer (NSCLC) admitted to the Second Affiliated Hospital of Xingtai Medical College from March 2017 to January 2019 were selected as the research objects and randomly divided into two groups, the control group and the observation group, with 35 patients in each group. Patients in the control group were treated with DP regimen, and docetaxel was given on day 1 and 8 by intravenous infusion, 60 mg/m2 and 250 mL 0.9% sodium chloride solution were fully mixed, once daily, on day 1 to 4, cisplatin was given intravenously, 30 mg/m2, once daily. All patients were treated with 3-week chemotherapy cycle for 2 consecutive cycles. Patients in the observation group was treated with ositinib at 80 mg/d for 2 courses of continuous treatment on the basis of the control group, and the clinical efficacy and other indicators were evaluated. The short-term efficacy of the two groups was observed, and the levels of tumor markers such as carcinoembryonic antigen (CEA), vascular endothelial growth factor (VEGF), cytokeratinin-19 fragment (CYFRA21-1), serum hCAPI8 and Pokemon expression, long-term survival and the occurrence of adverse reactions were compared between two groups before and after treatment. Results After treatment, the ORR and DCR of the observation group were 62.9% and 85.7%, respectively, and the ORR and DCR of the control group were 28.6% and 60.0%, respectively. The ORR and DCR of the observation group were significantly higher than those of the control group (P < 0.05). After treatment, the levels of CEA, VEGF and CYFRA21-1 in two groups were significantly decreased compared with those before treatment (P < 0.05). After treatment, the levels of CEA, VEGF and CYFRA21-1 in the observation group were significantly lower than those in the control group (P < 0.05). After treatment, the levels of serum hCAP18 and Pokemon in two groups were significantly decreased (P < 0.05). After treatment, the levels of hCAP18 and Pokemon in the observation group decreased more significantly (P < 0.05). After treatment, the levels of serum hCAP18 and Pokemon in two groups were significantly decreased (P < 0.05). After treatment, the levels of hCAP18 and Pokemon in the observation group decreased significantly (P < 0.05). The survival rate of observation group was significantly higher than that of control group (P < 0.05). Conclusions Osimertinib combined with DP regimen can effectively reduce the levels of CEA, VEGF and CYFRA21-1 in patients with advanced non-small cell lung cancer, effectively improve the patient's short-term efficacy and long-term survival, and the treatment process is safe and effective value."/>
