Multiple primary lung cancer displaying different EGFR and PTEN molecular profiles.

We present a case of multiple primary lung cancer(MPLC) displaying heterogeneous EGFR and PTEN molecular profiles. Considering the physical condition of patients, the patient underwent surgical resection of the right lung lesion displaying gefitinib-insensitive and continued gefitinib treatment for the gefitinib-sensitive lesions in the left lung. As far as we know, this is the first report documenting a case of an integrated therapy strategy using surgical resection with gefitinib treatment for MPLC displaying different EGFR and PTEN molecular profiles. The patient has been in progression free survival up to now. Our experience could provide a treatment strategy for patients with similar disease.
