Effects of KRAS, STK11, KEAP1, and TP53 mutations on the clinical outcomes of immune checkpoint inhibitors among patients with lung adenocarcinoma

This study aimed to identify the associations between individual KRAS, STK11, KEAP1, or TP53 mutations, as well as the comutation status of these genes, and the tumor mutation burden (TMB) with clinical outcomes of lung adenocarcinoma patients treated with immune checkpoint inhibitors (ICIs).

description This study aimed to identify the associations between individual KRAS, STK11, KEAP1, or TP53 mutations, as well as the comutation status of these genes, and the tumor mutation burden (TMB) with clinical outcomes of lung adenocarcinoma patients treated with immune checkpoint inhibitors (ICIs). We collected data from patients with lung adenocarcinoma treated with ICIs from the Center for Cancer Genomics and Advanced Therapeutics (C-CAT) database between June 2019 and August 2023. The main endpoints were the treatment response and overall survival (OS). Among 343 patients with lung adenocarcinoma, 61 (18%), 69 (20%), 41 (12%), and 222 (65%) patients had KRAS, STK11, KEAP1, and TP53 mutations, respectively. An overall objective response was observed in 94 of 338 patients (28%), including 2 (1%) who achieved a complete response and 92 (27%) who achieved a partial response. Patients with STK11, KEAP1, or TP53 mutations had a significantly greater TMB (P

According to the univariate analysis, the treatment response was significantly correlated with TP53 mutation in both the general (P = 0.041) and KRAS wild-type (P = 0.009) populations. KEAP1 and TP53 mutations were associated with worse OS among assessable patients (hazard ratio (HR) = 2.027, P = 0.002; HR = 1.673, P = 0.007, respectively) and among patients without KRAS mutations (HR = 1.897, P = 0.012; HR = 1.908, P = 0.004, respectively). According to the multivariate analysis, KEAP1 (HR = 1.890, P = 0.008) and TP53 (HR = 1.735, P = 0.011) mutations were found to be independent factors for OS. STK11, KEAP1, and TP53 mutations are significantly associated with a high TMB. TP53 mutation could affect the treatment response to some degree, and both KEAP1 and TP53 mutations resulted in inferior OS in the general patient population and in those with KRAS-wild-type lung adenocarcinoma, indicating that KEAP1 and TP53 mutations might act as prognostic factors for ICI treatment in lung adenocarcinoma patients.</description><identifier>ISSN: 1932-6203</identifier><identifier>EISSN: 1932-6203</identifier><identifier>DOI: 10.1371/journal.pone.0307580</identifier><identifier>PMID: 39037971</identifier><language>eng</language><publisher>United States: Public Library of Science</publisher><subject>Adenocarcinoma ; Adenocarcinoma of Lung - drug therapy ; Adenocarcinoma of Lung - genetics ; Adenocarcinoma of Lung - mortality ; Adenocarcinoma of Lung - pathology ; Adult ; Aged ; Aged, 80 and over ; AMP-Activated Protein Kinase Kinases ; Biology and Life Sciences ; Biomarkers ; Cancer ; Care and treatment ; Cell cycle ; Chemotherapy ; Clinical outcomes ; Female ; Genes ; Genetic aspects ; Genomics ; Humans ; Immune checkpoint inhibitors ; Immune Checkpoint Inhibitors - therapeutic use ; Inhibitors ; K-Ras protein ; Kelch-Like ECH-Associated Protein 1 - genetics ; Kinases ; Lung cancer ; Lung Neoplasms - drug therapy ; Lung Neoplasms - genetics ; Lung Neoplasms - mortality ; Lungs ; Male ; Medicine and Health Sciences ; Middle Aged ; Multivariate analysis ; Mutation ; p53 Protein ; Patient outcomes ; Patients ; Protein Serine-Threonine Kinases - genetics ; Proto-Oncogene Proteins p21(ras) - genetics ; Research and Analysis Methods ; Respiratory agents ; Signal transduction ; Treatment Outcome ; Tumor proteins ; Tumor Suppressor Protein p53 - genetics</subject><ispartof>PloS one, 2024-07, Vol.19 (7), p.e0307580</ispartof><rights>Copyright: © 2024 Liang et al.

We collected data from patients with lung adenocarcinoma treated with ICIs from the Center for Cancer Genomics and Advanced Therapeutics (C-CAT) database between June 2019 and August 2023. The main endpoints were the treatment response and overall survival (OS). Among 343 patients with lung adenocarcinoma, 61 (18%), 69 (20%), 41 (12%), and 222 (65%) patients had KRAS, STK11, KEAP1, and TP53 mutations, respectively. An overall objective response was observed in 94 of 338 patients (28%), including 2 (1%) who achieved a complete response and 92 (27%) who achieved a partial response. Patients with STK11, KEAP1, or TP53 mutations had a significantly greater TMB (P&lt;0.001). According to the univariate analysis, the treatment response was significantly correlated with TP53 mutation in both the general (P = 0.041) and KRAS wild-type (P = 0.009) populations. KEAP1 and TP53 mutations were associated with worse OS among assessable patients (hazard ratio (HR) = 2.027, P = 0.002; HR = 1.673, P = 0.007, respectively) and among patients without KRAS mutations (HR = 1.897, P = 0.012; HR = 1.908, P = 0.004, respectively). According to the multivariate analysis, KEAP1 (HR = 1.890, P = 0.008) and TP53 (HR = 1.735, P = 0.011) mutations were found to be independent factors for OS. STK11, KEAP1, and TP53 mutations are significantly associated with a high TMB. TP53 mutation could affect the treatment response to some degree, and both KEAP1 and TP53 mutations resulted in inferior OS in the general patient population and in those with KRAS-wild-type lung adenocarcinoma, indicating that KEAP1 and TP53 mutations might act as prognostic factors for ICI treatment in lung adenocarcinoma patients.</abstract><cop>United States</cop><pub>Public Library of Science</pub><pmid>39037971</pmid><doi>10.1371/journal.pone.0307580</doi><tpages>e0307580</tpages><orcidid>https://orcid.org/0009-0005-2365-1513</orcidid><orcidid>https://orcid.org/0000-0002-6849-2297</orcidid><oa>free_for_read</oa></addata></record>
