A patient with metastatic lung adenocarcinoma harboring concurrent EGFR L858R, EGFR germline T790M, and PIK3CA mutations: the challenge of interpreting results of comprehensive mutational testing in lung cancer.
Successful treatment of a patient with Li-Fraumeni syndrome and metastatic lung adenocarcinoma harboring synchronous EGFR L858R and ERBB2 extracellular domain S310F mutations with the pan-HER inhibitor afatinib.
Here, we report the case of a 72-year-old, never-smoker female diagnosed with multiple metastatic lung adenocarcinoma (cT2aN2M1) harboring EGFR mutations in exon 21 (L858R) of the primary lesion.
