A Phase III, Randomized, Multi-center Study to Determine the Efficacy of the Intercalating Combination Treatment of Chemotherapy and Gefitinib or Chemotherapy as Adjuvant Treatment in NSCLC With Common EGFR Mutations.

A Phase III, Randomized, Multi-center Study to Determine the Efficacy of the Intercalating Combination Treatment of Chemotherapy and Gefitinib or Chemotherapy as Adjuvant Treatment in NSCLC With Common EGFR Mutations.

This study aims to compare the efficacy of intercalating chemotherapy (gefitinib and pemetrexed/cisplatin) and chemotherapy (navelbine/cisplatin) in completely resected NSCLC with common EGFR mutations.

Inclusion Criteria:

1. Completely resected non-squamous cell NSCLC with stage IIa to IIIb (excluding N3) according to Version 8 of the IASLC Staging Manual in Thoracic Oncology
2. Tumors with common EGFR mutations (19del or L858R)
3. Adequate oran function

Exclusion Criteria:

1. Patients who were exposed to the chemotherapy or EGFR TKIs for NSCLC.
2. Patients with interstitial lung disease
