Meta-analysis of the efficacy of immune checkpoint inhibitors in the treatment of NSCLC with different KRAS genotypes
To evaluate the efficacy of immune checkpoint inhibitors (ICIs) in the treatment of non-small cell lung cancer (NSCLC) with different
KRAS
genotypes.
METHODS
2
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
2
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
2
ICIs show significant efficacy in NSCLC patients, and NSCLC patients benefit equally regardless of whether
KRAS
mutations occur.
