Excerpt:
the Food and Drug Administration approved osimertinib (Tagrisso, AstraZeneca Pharmaceuticals) for adult patients with locally advanced, unresectable (stage III) non-small cell lung cancer (NSCLC) whose disease has not progressed during or following concurrent or sequential platinum-based chemoradiation therapy and whose tumors have EGFR exon 19 deletions or exon 21 L858R mutations, as detected by an FDA-approved test.

Efficacy of Osimertinib in Lung Squamous Cell Carcinoma Patients with EGFR Gene Mutation–Case Report and a Literature Review

Published date:

Excerpt:
The hereby presented patient fitted the ADC characteristics, while they were diagnosed with SCC. The unusual diagnosis implied further genetic testing, which established the occurrence of L858R substitution in exon 21 in the EGFR gene….Due to EGFR gene mutation, the woman was administered osimertinib, however, the treatment did not succeed...The patient died 10 months after diagnosis.
