摘 要：Background:Immune checkpoint inhibitors(ICIs) have become an effective treatment option for ***,EGFR and TP53 are common mutated oncogenes in cancer whose single gene status may predict the therapeutic effect of clinical *** this efficacy evaluation,we aimed to clarify whether the single gene mutation status of KRAS,EGFR or TP53 affects the survival benefits of ICIs in cancer ***:We used PubMed,Cochrane Library,web of science,and clinical trials Gov database to retrieve qualified documents,the time was up to January *** ratios(HRS) and 95%confidence intervals(CIs) were used to determine the single gene mutation status and no progression of KRAS,EGFR or ***:A total of 19 studies included 7029 cancer patients treated with *** results showed that KRAS,EGFR or TP53 single gene mutation could significantly improve PFS and OS in patients receiving ICIs,but the degree of improvement was *** risk of prolongation of PFS(HR= 1.48,95% CI= 1.19-1.85,P= 0.0004) and OS(HR= 1.68,95%CI= 1.36-2.07,P0.00001) caused by TP53 single gene mutation was relatively high,the risk ratio of prolongation of PFS(HR= 1.38,95% CI= 1.21-1.57,P0.00001) and OS(HR= 1.56,95% CI= 1.20-2.04,P= 0.001) caused by EGFR single gene mutation was the second,the risk ratio of prolongation of PFS(HR= 1.33,95% CI= 1.12-1.57,P= 0.001) and OS(HR=1.39,95% CI= 1.18-1.63,P0.00001) caused by KRAS single gene mutation was relatively low,and the results were significantly ***:In cancer patients,KRAS,EGFR or TP53 single gene status is correlated with the benefits of immunotherapy PFS and OS,which suggests that gene sequencing should be carried out in time in the process of clinical treatment to determine the gene mutation of patients and better predict the clinical treatment effect of ICIs.
