The high incidence and poor prognosis of lung cancer represent a major health problem. Currently, about 20% of lung cancer patients can benefit from targeted therapy after identification of EGFR, ALK or HER2 somatic mutations or rearrangements. Other mutations, such as KRas oncogenic mutation, are still orphans of validated targeted therapy. In this review, we describe the different mouse models of lung carcinoma. We then illustrate the interests of such models for the identification and validation of new therapeutic targets, for the study of secondary resistance and for their use as preclinical models and for new therapeutic strategy tests.
