          摘  要  目的  评价免疫检查点抑制剂(ICIs)用于鼠类肉瘤病毒癌基因(KRAS)基因不同分型非小细胞肺癌(NSCLC)的疗效。
          方法  计算机检索PubMed、the Cochrane Library、Web of Science、Embase、中国知网、万方数据、维普网,收集ICIs单药或多种ICIs
          联用或ICIs联合传统化疗(试验组)对比传统化疗(对照组)用于NSCLC的随机对照试验(RCTs),检索时限为建库至2023年4月1
          日。筛选文献、提取数据和评价质量后,采用 RevMan 5.4 软件进行 Meta 分析、敏感性分析和发表偏倚分析。结果  共纳入 7 项
          RCTs,合计5 980例患者。Meta分析结果显示,试验组患者的总生存期(OS)[HR=0.79,95%CI(0.72,0.87),P<0.000 01]、无进展
          生存期(PFS)[HR=0.63,95%CI(0.50,0.80),P=0.000 2]均显著长于对照组,且试验组 KRAS 突变型[HR=0.63,95%CI(0.53,
          0.75),P<0.000 01]、KRAS野生型[HR=0.87,95%CI(0.78,0.98),P=0.02]患者的OS,KRAS突变型[HR=0.58,95%CI(0.43,0.78),
          P=0.000 3]、KRAS野生型[HR=0.68,95%CI(0.47,0.99),P=0.04]患者的PFS均显著长于对照组;按不同治疗方案进行亚组分析
          的结果显示,试验组使用一、二线治疗方案,单用ICIs,使用ICIs联合传统化疗的KRAS突变型患者的OS,以及试验组使用一线治
          疗方案的 KRAS突变型、KRAS野生型患者的 PFS 均显著长于对照组(P<0.05)。敏感性分析结果显示,本研究所得结果较稳健。
          发表偏倚结果显示,本研究存在发表偏倚的可能性较小。结论  ICIs用于NSCLC患者的疗效显著,且无论是否发生KRAS突变,
          NSCLC患者都同样受益。

          ABSTRACT   OBJECTIVE  To  evaluate  the  efficacy  of  immune  checkpoint  inhibitors (ICIs)  in  the  treatment  of  non-small  cell
          lung  cancer (NSCLC)  with  different  KRAS  genotypes.  METHODS  Retrieved  from  PubMed,  the  Cochrane  Library,  Web  of
          Science, Embase, CNKI, Wanfang data and VIP, randomized controlled trials (RCTs) about ICIs alone, combined use of various
          ICIs  or  ICIs  combined  with  traditional  chemotherapy (trial  group)  versus  traditional  chemotherapy (control  group)  for  NSCLC
          were  collected  from  the  inception  of  the  databases  to  April  1,  2023.  After  screening  literature,  extracting  data  and  evaluating
          quality, meta-analysis, sensitivity analysis and publication bias analysis were conducted by using RevMan 5.4 software. RESULTS
          A total of 7 RCTs involving 5 980 patients were included. The results of the meta-analysis showed that overall survival (OS) [HR=
          0.79,  95%CI (0.72,  0.87),  P<0.000  01]  and  progression-free  survival (PFS)  [HR=0.63,  95%CI (0.50,  0.80),  P=0.000  2]  of
          trial  group  were  significantly  longer  than  those  of  control  group;  furthermore,  the  OS  of  KRAS  mutant  type  [HR=0.63,  95%CI
         (0.53,  0.75),  P<0.000  01]  and  KRAS  wild  type  [HR=0.87,  95%CI (0.78,  0.98),  P=0.02],  PFS  of  KRAS  mutant  type  [HR=
          0.58, 95%CI (0.43, 0.78), P=0.000 3] and KRAS wild type [HR=0.68, 95%CI (0.47, 0.99), P=0.04] in the trial group were
          all  significantly  longer  than  in  the  control  group.  Subgroup  analysis  by  different  treatment  regimens  showed  that  the  OS  of  KRAS
          mutant  type  patients  receiving  first-  and  second-line  treatment  regimens,  using  ICIs  alone  and  those  receiving  ICIs  combined  with
          traditional  chemotherapy  as  well  as  PFS  of  KRAS  mutant  type  and  wild  type  patients  receiving  first-line  treatment  regimens  in  the
          trial  group  were  all  significantly  longer  than  in  the  control  group (P<0.05).  Sensitivity  analysis  results  indicated  that  the  findings
          of  this  study  were  robust.  Publication  bias  results  showed  that  the  possibility  of  publication  bias  in  this  study  was  small.
                                                             CONCLUSIONS  ICIs  show  significant  efficacy  in  NSCLC
