          摘   要  目的  评价程序性死亡受体1(PD-1)/程序性死亡配体1(PD-L1)抑制剂用于膀胱癌新辅助治疗的疗效和安全性,为临床
          治疗提供循证依据。方法  计算机检索 PubMed、the Cochrane Library、Embase、American Society of Clinical Oncology Meeting Li‐
          brary、中国知网、维普网及万方数据等,收集PD-1/PD-L1抑制剂用于膀胱癌新辅助治疗的随机对照试验(RCT)、非RCT、病例对照
          研究、队列研究等,检索时限为建库起至2023年1月31日。筛选文献,提取资料及质量评价后,采用RevMan 5.3软件进行单组率
          Meta分析,采用Stata12软件进行敏感性分析和发表偏倚分析。结果  共纳入25项研究,共计940例患者。Meta分析结果显示,患
          者的病理完全缓解(pCR)率为 32%[OR=0.32,95%CI(0.22,0.45),P=0.006],降期率为 52%[OR=0.52,95%CI(0.45,0.60),P=
          0.55],3级及以上免疫相关不良反应(Grade≥3 irAEs)发生率为16%[OR=0.16,95%CI(0.11,0.22),P<0.000 01]。亚组分析结果
          显示,pCR 率和 Grade≥3 irAEs 发生率在单用 PD-1/PD-L1 抑制剂患者中分别为 25%、9%,在联合免疫治疗患者中分别为 29%、
          28%,在PD-1/PD-L1抑制剂联合化疗患者中分别为43%、12%;PD-L1阳性患者的pCR率为44%,PD-L1阴性患者为25%。敏感性
          分析结果显示,本研究所得结果稳健。发表偏倚分析结果显示,本研究存在发表偏倚可能性较小。结论  PD-1/PD-L1抑制剂用于
          膀胱癌新辅助治疗的疗效和安全性均较好。

          ABSTRACT    OBJECTIVE  To  evaluate  the  efficacy  and  safety  of  PD-1/PD-L1  inhibitors  for  neoadjuvant  treatment  of  bladder
          cancer,  and  to  provide  evidence-based  reference  for  clinical  treatment.  METHODS  Retrieved  from  PubMed,  Cochrane  Library,
          Embase,  American  Society  of  Clinical  Oncology  Meeting  Library,  CNKI,  VIP  and  Wanfang  database,  etc.,  the  randomized
          controlled  trials (RCTs),  non-RCT,  case-control  studies,  cohort  studies,  etc.  about  PD-1/PD-L1  inhibitors  for  neoadjuvant
          treatment  of  bladder  cancer  were  collected  from  the  inception  to  Jan  31st,  2023.  After  literature  screening,  data  extraction  and
          quality  evaluation,  RevMan  5.3  software  was  used  to  perform  meta-analysis  of  single-group  rates;  sensitivity  analysis  and
          publication bias analysis were conducted using Stata12 software. RESULTS A total of 25 studies were included in this discussion,
          involving 940 patients. The results of meta-analysis showed that the pathologic complete response (pCR) rate was 32% [OR=0.32,
          95%CI (0.22, 0.45), P=0.006], downstaging rate was 52% [OR=0.52, 95%CI (0.45, 0.60), P=0.55], and the incidence of ≥grade
          3  immune-related  adverse  events (irAEs)  was  16%  [OR=0.16,  95%CI (0.11,  0.22),  P<0.000  01].  Subgroup  analysis  showed
          that  the  patients  receiving  PD-1/PD-L1  inhibitors  alone  had  a  pCR  rate  of  25%  and  a  incidence  of  Grade≥3  irAEs  of  9%;  the
          patients  receiving  combined  immunotherapy  had  a  pCR  rate  of  29%  and  a  incidence  of  Grade≥3  irAEs  of  28%;  the  patients
          receiving PD-1/PD-L1 inhibitors combined with chemotherapy had a pCR rate of 43% and a incidence of Grade≥3 irAEs of 12%;
          PD-L1 positive patients had a pCR rate of 44%, and PD-L1 negative patients had a pCR rate of 25%. The results of the sensitivity
          analysis  showed  that  the  study  was  robust.  The  results  of  the  publication  bias  analysis  showed  that  there  was  no  significant
                                                              publication  bias.  CONCLUSIONS  PD-1/PD-L1  inhibitors  are
