Abstract:
Objective:To explore the efficacy of atezolizumab combined with anlotinib in treating advanced non-small cell lung cancer (NSCLC) .Methods:A total of 80 patients with advanced NSCLC treated in the Baoding No.2 Central Hospital from September 2019 to September 2023 after second-line treatment were selected as research subjects. Patients who received only anlotinib treatment were included in the monotherapy group ( n=40), while patients who received atezolizumab combined with anlotinib treatment were included in the combination group ( n=40). The clinical efficacy and serum levels of carcinoembryonic antigen (CEA) and vascular endothelial growth factor (VEGF) of the two groups were compared. Kaplan-Meier survival curve was used to analyze the survival of the two groups. The functional assessment of cancer therapy-lung cancer (FACT-L) was used to assess the quality of life of patients in both groups before and after treatment. The incidence of adverse reactions was compared between the two groups. Results:After four cycles of treatment, the objective response rate (ORR) of the combination group was 37.50% (15/40), which was higher than that of the monotherapy group [17.50% (7/40) ], with a statistically significant difference ( χ2=4.01, P=0.045). The disease control rates (DCRs) of the two groups were 85.00% (34/40) and 75.00% (30/40), respectively, with no statistically significant difference ( χ2=1.25, P=0.264). Before treatment, the CEA levels in combination group and monotherapy group were (10.18±2.15) and (10.14±2.02) μg/L, and the VEGF levels were (804.04±46.58) and (809.10±43.63) ng/L, respectively, with no statistically significant difference (both P>0.05). After treatment, the serum CEA levels of patients in combination group and monotherapy group were (4.35±1.05) and (6.63±1.37) μg/L, and the VEGF levels were (431.26±50.19) and (549.92±55.27) ng/L, respectively, with statistically significant differences ( t=8.35, P<0.001; t=10.05, P<0.001), and the levels of serum CEA and VEGF in the two groups after treatment were lower than before treatment ( t=32.47, P<0.001; t=21.73, P<0.001; t=88.65, P<0.001; t=58.27, P<0.001). Survival analysis showed that the median progression-free survival (PFS) of the monotherapy group and the combination group were 4.12 and 6.06 months, respectively, with a statistically significant difference ( χ2=17.70, P<0.001), the median overall survival (OS) were 11.8 and 12.7 months, respectively, with no statistically significant difference ( χ2=3.09, P=0.079). Before treatment, the FACT-L scores of patients in combination group and monotherapy group were 61.20±6.98 and 60.52±7.14, respectively, with no statistically significant difference ( t=0.43, P=0.668). After treatment, the FACT-L scores of the two groups were 83.24±9.38 and 74.58±7.86, respectively, with a statistically significant difference ( t=4.48, P<0.001), and the FACT-L scores of the two groups after treatment were all higher than before treatment ( t=29.36, P<0.001; t=21.51, P<0.001). During treatment, the total incidence of drug-related adverse reactions in two groups was 42.50% (17/40) and 55.00% (22/40), respectively, with no statistically significant difference ( χ2=1.25, P=0.263) . Conclusions:Atezolizumab combined with anlotinib in the treatment of advanced NSCLC can enhance the short-term efficacy, prolong the PFS of patients, improve the quality of life, and the related adverse reactions are tolerable.
