In each independent cohort, as well as in the combined cohort, STK11 and KEAP1 mutations were associated with significantly worse progression-free (STK11 HR: 2.04, P<0.0001; KEAP1 HR 2.05, P<0.0001), and overall survival (STK11 HR: 2.09 ,P<0.0001; KEAP1 HR 2.24, P<0.0001) to immunotherapy uniquely among KRAS MUT but not KRAS WT LUADs.
