Primary Objective: To compare disease-free survival (DFS) in the intent-to-treat patient population, among patients randomized to receive atezolizumab for one year (Arm B) vs. observation (Arm A). DFS is defined as the time from randomization to the occurrence of any of the three events disease recurrence, second lung primary, and death, whichever comes first Secondary Objectives: 2.2.1 To compare overall survival (OS) between patients randomized to atezolizumab versus observation. 2.2.2 To compare recurrence-free survival (RFS) between patients randomized to atezolizumab versus observation. 2.2.3 To compare lung-cancer-specific OS between patients randomized to atezolizumab versus observation. 2.2.4 To compare rates of loco-regional recurrences between patients randomized to atezolizumab versus observation. 2.2.5 To compare rates of distant recurrences between patients randomized to atezolizumab versus observation. 2.2.6 To compare adverse event rates (AEs) via CTCAE v5 between patients randomized to atezolizumab versus observation.
