Abstract
Objective To compare the clinical efficacy of epidermal growth factor receptor-tyrosine kinases inhibitor (EGFR-TKI)alone and bevacizumab in combination with EGFR-TKI in the treatment of ad-vanced non-small cell lung cancer (NSCLC)with EGFR exon 19 or 21 mutation. Methods In total,100 ad-vanced NSCLC patients with EGFR mutation,50 with EGFR exon 19 mutation and 50 with EGFR exon 21 mu-tation,were randomly divided into two groups. In group A,patients were treated with bevacizumab in combina-tion with gefitinib until disease progression and those in group B were given with gefitinib alone until disease progression. The incidence of adverse responses,objective remission rate (ORR),progression-free survival (PFS)and overall survival (OS)were statistically compared between two groups. Results For NSCLC pa-tients with exon 19 mutation,the ORR in group A was 92%,significantly higher compared with 68%in group B (P<0.05). For their counterparts with exon 21 mutation,the ORR in group A was 88%,considerably higher than 60% in group B (P<0.05). For patients with exon 19 mutation,the median PFS in group A was 12.5 months,significantly longer compared with 9.0 months in group B (P<0.05). The median PFS of pa-tients with exon 21 mutation in group A was 8.9 months,remarkably higher than 7.0 months in group B (P<0.01). For patients with exon 19 mutation,the median OS did not significantly differ between groups A and B (P>0.05). The median PFS of patients with exon 21 mutation in group A was 8.9 months,remarkably higher than 7.0 months in group B (P<0.01). For patients with exon 21 mutation,the median OS in group A was 26.7 months,significantly longer compared with 23.8 months in group B (P<0.01 ). For NSCLC patients with exon 19 and 21 mutation,the incidence of tolerable hypertension and albuminuria in group A was signifi-cantly higher than that in group B (both P<0.05 ). Conclusions Bevacizumab in combination with EGFR-TKI serves as a novel option in the management of advanced NSCLC with EGFR mutation,especially those with exon 21 mutation. The PFS and OS of patients receiving bevacizumab combined with EGFR-TKI are prolonged compared with those treated with EGFR-TKI alone.关键词
