In
patients with advanced
non-small cell lung cancer harboring
epidermal growth factor receptor (EGFR)
mutations, the
epidermal growth factor receptor-
tyrosine kinase inhibitors (EGFR-TKIs) are used as first
treatment option. Because
adenosquamous carcinoma (ASC) is a rare histologic subtype, evidences about EGFR-TKIs as first
treatment option for advanced ASC are lacking. We
report a case of an advanced ASC
patient with the EGFR
mutation,
who showed good responses during 4-month
treatment with
gefitinib. And we
will review about a necessity of EGFR
mutation test and
efficacy of EGFR-TKIs in ASC
patients from the recent studies.
