Crizotinib (Xalkori) is an orally available small molecule tyrosine kinase inhibitor proven in clinical trials to significantly impact progression free survival and overall response rate. We present a case of a 56-year-old male with NSCLC whose lack of a positive treatment response to this therapy led to the clinical suspicion and identification of the underdiagnosed entity known as synchronous multiple primary lung cancer (SMPLC).展开更多
