          P=0.01]、无进展生存期(PFS)[HR=0.67,95%CI(0.57,0.79),P<0.000 01]均显著高于对照组;两组患者的3级及以上不良事件发

          ABSTRACT    OBJECTIVE  To  systematically  evaluate  the  efficacy  and  safety  of  immune  checkpoint  inhibitors (ICIs)  in  the
          treatment  of  metastatic  colorectal  cancer (mCRC),  so  as  to  provide  evidence-based  reference  for  clinical  practice.  METHODS
          PubMed,  the  Cochrane  Library,  Web  of  Science,  Embase,  CNKI,  Wanfang  and  VIP  databases  were  searched  to  collect
          randomized  controlled  trials (RCT)  of  ICIs (trial  group)  versus  traditional  chemotherapy  or  optimal  supportive  treatment (control
          group)  in  the  treatment  of  mCRC  from  the  establishment  of  the  database  to  June  1,  2022.  After  literature  screening  and  data
          extraction, Cochrane Systematic Review Manual 5.1.0 was used to evaluate the quality of the included literature, and RevMan 5.4
          software  was  used  for  meta-analysis  and  sensitivity  analysis.  RESULTS  A  total  of  4  RCTs  were  included,  involving  833  patients.
          Meta-analysis  showed  that  the  overall  survival (OS)  [HR=0.77,  95%CI (0.64,  0.94),  P=0.01]  and  progression-free  survival
         (PFS)  [HR=0.67,  95%CI (0.57,  0.79),  P<0.000  01]  were  significantly  higher  in  trial  group  than  control  group;  the  difference
          was  not  statistically  significant  when  comparing  the  incidence  of  grade  3  and  above  adverse  events  in  the  two  groups  [RR=1.22,
          95%CI (0.77,  1.94),  P=0.39].  Subgroup  analysis  by  mutation  pattern  showed  that  patients  with  mismatch  repair  proficiency  and
          low levels of microsatellite instability (pMMR-MSS) mCRC patients in trial group had significantly higher PFS than control group
         (P<0.05).  The  results  of  sensitivity  analysis  showed  that  the  results  were  robust.  CONCLUSIONS  Compared  with  traditional
          chemotherapy  or  optimal  supportive  treatment,  ICIs  can  prolong  the  OS  and  PFS  of  mCRC  patients,  and  maybe  has  more
          advantages  in  pMMR-MSS  mCRC  patients;  the  safety  of  ICIs  is  equivalent  to  that  of  traditional  chemotherapy  or  optimal
          supportive treatment.
