      factor receptor tyrosine kinase inhibitor in patients with locally advanced or Metastatic Non
      Small Cell Lung Cancer
    

Eligibility criteria:

        Inclusion Criteria:

          1. Male or female, aged at least 18 years.

          2. Pathologically confirmed adenocarcinoma of the lung.

          3. Locally advanced or metastatic NSCLC, not amenable to curative surgery or
             radiotherapy.

          4. The tumour harbours one of the 2 common EGFR mutations known to be associated with
             EGFR-TKI sensitivity (Ex19del, L858R).

          5. Mandatory provision of an unstained, archived tumour tissue sample in a quantity
             sufficient to allow for central analysis of EGFR mutation status.

          6. Patients must be treatment-naïve for locally advanced or metastatic NSCLC and eligible
             to receive first-line treatment with gefitinib or erlotinib as selected by the
             participating centre. Prior adjuvant and neo-adjuvant therapy is
             permitted(chemotherapy, radiotherapy, investigational agents).

          7. Provision of informed consent prior to any study specific procedures, sampling, and
             analysis.

          8. World Health Organization Performance Status of 0 to 1 with no clinically significant
             deterioration over the previous 2 weeks and a minimum life expectancy of 12 weeks
