We found that the objective response rates (ORRs) associated with ICI treatments in lung cancers harboring the BRAF (0–54%), c-MET (12–49%), and KRAS (18.7-66.7%) alterations were comparable to non-mutant NSCLC, whereas the ORRs in RET fusion NSCLC (less than10% in all studies but one) and ALK fusion NSCLC (0%) were relatively low. This evidence concerns the gene ALK and non-small cell lung carcinoma.
