研究目的：
Many patients with oncogene-driven non-small-cell lung cancer (NSCLC) treated with tyrosine kinase inhibitors experience limited sites of disease progression. For multiple metastases in patients with advanced NSCLC,increased local treatment may benefit to prolong patient survival. This study investigated the benefits of icotinib limited systemic disease progression and continuation of Stereotactic Body Radiation Therapy,in patients with metastatic EGFR-mutant NSCLC.
