In this prospective, single arm, phase II study, patients with advanced NSCLC were treated with EGFR-TKI (icotinib 125 mg tid or gefitinib 250 mg qd) for one month followed by SBRT (40–60 Gy/5–8 F/5–10 d) to the primary tumor with concurrent EGFR-TKI until disease progression. This evidence concerns the gene EGFR and non-small cell lung carcinoma.
