Particularly interesting were the results of a study performed by Hong and coworkers based on the screening of a total 1160 Chinese NSCLC patients: 78% lung adenocarcinomas, 54% never-smokers, 33.8% with EGFR mutations and 8.1% with EML4-ALK rearrangements [325]. Here, EGFR is linked to lung adenocarcinoma.
