This is a phase II, multi-center study. Sixty-seven patients are planned to be enrolled. All patients will receive Icotinib 125 mg BID administered for 8 weeks. Patients with a complete response, partial response or stable disease at that time may continue to be treated based on physician discretion. Follow up is then required until resolution or stabilization of any treatment-related toxicity, and patients with stable disease or objective responses must also continue evaluations until survived.
