You may receive treatment in the study for up to 1 year (3 cycles of cisplatin/docetaxel and then daily erlotinib for up to 1 year) and will receive long-term follow-up (for 5 years total) with your physician to monitor your condition and disease status. Your doctor may decide to take you off this study if you experience significant side effects or your medical condition worsens. Follow-up visits will include a chest x-ray and CT scan every 3 months during Year 2 and then every 6 months until Year 5.
