The purpose of this study is to assess the effect and safety of erlotinib versus NVB plus cisplatin (NP) as adjuvant treatment in patients with stage IIIA NSCLC after complete resection with EGFR activating mutations and to explore a new treatment strategy for this subset.

The LACE meta-analysis identified four cycles of platinum-based program to improve II~IIIA stage completely resected NSCLC pts the role of 5-year survival, but its treatment-related life threatening toxicity limits its use. The EGFR tyrosine kinase inhibitor (TKI) may provide a dramatic response in pts with pulmonary adenocarcinoma carrying EGFR activating mutations in the metastatic setting. The aim of this study is to investigate the efficacy and safety of erlotinib versus NVB plus cisplatin (NP) as adjuvant treatment in pts with stage IIIA NSCLC after Complete Resection with EGFR activating mutations and to explore a new treatment strategy for this subset.

Exclusion Criteria:

• Patients with prior chemotherapy or therapy with systemic anti-tumour therapy.
• Patients with prior radiotherapy.
• History of another malignancy in the last 5 years with the exception of the following:Cured basal cell carcinoma of the skin and cured in situ carcinoma of the uterine cervix are permitted.
