赛沃替尼在Ⅲ/Ⅳ期非小细胞肺癌中的疗效观察

Therapeutic Effect of Savolitinib in Patients with Stage Ⅲ/Ⅳ Non-small Cell Lung Cancer

  • 摘要:
    目的  分析赛沃替尼在Ⅲ/Ⅳ期非小细胞肺癌(NSCLC)患者中的治疗效果。
    方法  采用随机数字表法将95例MET 14外显子(METex14)跳跃突变的Ⅲ/Ⅳ期NSCLC患者分为对照组(47例)与观察组(48例)。对照组给予克唑替尼治疗,观察组给予赛沃替尼治疗。采用卡方检验分析两组临床疗效及不良反应发生情况,Kaplan-Meier生存分析评估两组患者生存情况。
    结果  观察组客观缓解率(ORR)和疾病控制率(DCR)分别为52.08%和87.50%,均高于对照组的31.91%和70.21%(P<0.05);Kaplan-Meier生存分析显示,观察组总生存期(OS)和无进展生存期(PFS)长于对照组(Log rank χ2=8.003、4.528,P=0.005、0.033);两组不良反应程度比较差异无统计学意义(P>0.05)。
    结论  赛沃替尼可提高Ⅲ/Ⅳ期METex14跳跃突变NSCLC患者的治疗效果,延长患者的生存期,且患者对赛沃替尼的耐受性较好,不良反应可控。

     

    Abstract:
    Objective To analyze therapeutic effect of savolitinib in patients with stage Ⅲ/Ⅳ non-small cell lung cancer (NSCLC).
    Methods A total of 95 patients with MET 14 exon (METex14) jumping mutation in stage Ⅲ/Ⅳ NSCLC were divided into a control group (47 cases) and an observation group (48 cases) through a random-number table method. The patients in the control group were treated with crizotinib, whereas those in the observation group were treated with savolitinib. The clinical efficacy and incidence of toxic side effects in both groups were evaluated through a chi-square test, and survival was evaluated through Kaplan-Meier survival analysis.
    Results  Compared with control group (31.91% and 70.21%), the objective response rate and disease control rate of the observation group were 52.08% and 87.50%, respectively (P<0.05). According to Kaplan-Meier survival analysis, the overall survival and progression free survival rates in the observation group were higher than those in the control group (Log rank χ2=8.003, 4.528; P=0.005, 0.033). No statistically significant difference in the degree of toxic side effects was found between the groups (P>0.05).
    Conclusion Savolitinib can improve the efficacy of treatment for stage Ⅲ/Ⅳ METex14 skip mutation NSCLC patients, prolong survival, enhance the tolerance of patients to savolitinib, and facilitate the management of adverse reactions.
