We conducted a systematic search of randomized control clinical trials investigating IO, alone or with chemotherapy (CT), vs CT alone vs chemoimmunotherapy (CIT) in treatment-naïve advanced NSCLC patients...Our search resulted in 2140 publications and a total of 6658 patients with advanced NSCLC across 9 controlled clinical trials were included. We found that 7 trials demonstrated that patients with KRAS mutation and STK11 and /or KEAP11 loss responded poorly to PDL1 therapy. They have shorter DFS and/or OS.
