This is a Phase III study is for patients that have been diagnosed with with early-stage non-small cell lung cancer. The primary purpose of this study is to see if there is a difference in overall survival rate in patients changes based on when they start their drug treatment, either before or after surgical intervention. Participants in this study can expect to be followed for up to 10 years. This study has two groups and a computer will be used to assign study groups. Participants will be randomly assigned to receive either neoadjuvant therapy followed by surgery and adjuvant therapy, or surgery followed by adjuvant therapy. This is called randomization. Patients will have an equal chance of being in either group, similar to flipping a coin.
