abstract = {Purpose: A number of different clinical characteristics have been reported to singly correlate with therapeutic activity of epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) in advanced non-small-cell lung cancer (NSCLC). This study aimed to identify predictive factors associated with prognostic benefits of gefitinib.
Patients and methods: EGFR gene typing in 33 advanced NSCLC patients received gefitinib (250 mg/day) were analyzed with mutant-enriched PCR assay. Gefitinib response was evaluated with potential predictive factors retrospectively.
Results: The overall objective response rate (ORR) and median progression-free survival (PFS) in the 33 patients treated by gefitinib were 45.5% and 3.0 (2.0-4.0) months. The ORR and median PFS in EGFR gene mutation patients were significantly higher/longer than those in EGFR gene wild-type patients (P},
