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


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 -C- 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.
