Fig 1 Overall survival curves of the cohort stratified by pathologic stage. The cumulative 5-year survival rate of each stage is shown. The Annals of Thoracic Surgery 2016 101, 1877-1882DOI: (10.1016/j.athoracsur.2015.11.067) Copyright © 2016 The Society of Thoracic Surgeons Terms and Conditions
Fig 2 The changes of 5Y-CS based on (A) overall survival, (B) lung cancer–specific survival, and (C) recurrence-free survival. In this study, 5Y-CS(x) was defined as the survival probability of the next 5 years at some years after operation (x). The 5Y-CS(1), 5Y-CS (2), 5Y-CS(3), and 5Y-CS(4) in all patients showed gradual improvement.

Fig 3 The change in 5Y lung cancer–specific CS when adjusted for (A) age, (B) sex, (C) histologic type, or (D) smoking status. The Annals of Thoracic Surgery 2016 101, 1877-1882DOI: (10.1016/j.athoracsur.2015.11.067) Copyright © 2016 The Society of Thoracic Surgeons Terms and Conditions
Fig 4 The changes of 5Y-CS(0), 4Y-CS(1), 3Y-CS(2), 2Y-CS(3), and 1Y-CS(4) based on (A) overall survival, (B) lung cancer–specific survival, and (C) recurrence-free survival. These factors were defined as the probability of surviving at 5 postsurgical years after a specific time.

Fig 5 (A and B) The change in 5Y-CS and 5Y-CS(0), 4Y-CS(1), 3Y-CS(2), 2Y-CS(3), and 1Y-CS(4) in women and those with adenocarcinoma histologic type, pathologic stage I, and normal serum carcinoembryonic antigen (CEA) levels (red). These same factors in male patients with squamous cell carcinoma are shown in blue.
