Concomitant EGFR mutation and ALK rearrangement in lung adenocarcinoma is more frequent than expected: report of a case and review of the literature with demonstration of genes alteration into the same tumor cells.

Abstract excerpt

Oncogenic drivers in lung non-small-cell lung cancer (NSCLC) are considered mutually exclusive, but a review of the literature reveals that concomitant EGFR mutations and ALK rearrangement may occur in a subset of NSCLC. We report here a case of pulmonary adenocarcinoma with concomitant EGFR mutation in exon 21 (L858R) and ALK rearrangement in naive and relapsed tumors. Tumor cells seem to harbor both gene...
