Brief summary: To investigate the survival benefit of first-line therapy for patients with EGFR-sensitive mutation-positive advanced non-squamous non-small cell lung cancer treated with S-1plus gefitinib versus gefitinib monotherapy

Detailed description: This is a randomized, controlled, open-plan, prospective clinical study. According to the available evidence, we selected patients with locally advanced or metastatic non-squamous non-small cell lung cancer with stage Ⅲ-C-Ⅳ confirmed by cytology or histology and positive EGFR-sensitive mutation, then patients accept first-line treatment with S-1 plus gefitinib or gefitinib. This study will collect FFS during treatment until the patient dies and will follow the survival of the subject after the disease progresses.

Eligibility criteria: Inclusion Criteria:

1. Volunteered for attending the study, and signed informed consent form (ICF)to participate in the study.
2. Males or females aged ≥18 years, \< 75 years.
3. Cytologically and Histologically documented, advanced or recurrent (stage IIIc-IV) non-small cell lung cancer patients .
4. exon 19 deletion or exon 21 L858R for EGFR mutation.
5. Patients hadn't received past system treatment, including cytotoxic drugs; For patients who have received adjuvant or neoadjuvant chemotherapy appears recurrence or metastasis more than 6 months from accepting the last dose of chemotherapy drugs
6. Patients must have at least 1 measurable lesion according to the RECIST (version 1.1) criteria.
7. Life expectancy ≥12 weeks.
8. ECOG performance status 0-2.
9. Adequate organ function as defined by the following criteria:

3. Patients with prior exposure to EGFR-TKIs or 5-Fu
4. Not recovered from previous toxic reactions for anticancer treatment (CTCAE grade 1) or not fully recovered from previous surgery
5. Patients who have brain metastasis. It is permitted if the patient has been treated with surgery and/or radiation with evidence of stable disease for at least 4 weeks.
6. Patients haven't been diagnosed other malignant disease, except the basal cell carcinoma and cervical carcinoma.
7. A uncontrolled clinical infection, activity, including acute pneumonia,HIV,HCV. , etc.
8. Sullivudine, brivudine or other antiviral drugs of similar structure were used within 2 months before randomization

13. Patients with medical history of hemoptysis (defined as about 2.5ml bright blood) 2 weeks before the enrollments
14. Stroke and transient ischemic in 12 months before enrollment.
15. Severe ulcer in the skin wound, trauma and mucosa or fractures have been not fully healed.
16. Patients received CYP3A4 strong inhibitor and/or inducer in 2 weeks before enrollment; Patients received P-gp and breast cancer resistance protein (BCRP) substrates drug in 2 weeks before enrollment.
