1 Relationship Between Functional Preservation after Segmentectomy and Volume- Reduction Effects after Lobectomy in Stage I Non-small Cell Lung Cancer Patients with Emphysema  Kosuke Kashiwabara, MD, Ji-Ichiro Sasaki, MD, Tsuyoshi Mori, MD, Hiroaki Nomori, MD, Kazuhiko Fujii, MD, Hirotsugu Kohrogi, MD  Journal of Thoracic Oncology  Volume 4, Issue 9, Pages (September 2009) DOI: /JTO.0b013e3181ae59e2 Copyright © 2009 International Association for the Study of Lung Cancer Terms and Conditions

2 FIGURE 1 Postoperative change of the FVC and the FEV1 between the lobectomy group and the segmentectomy group in patients with stage I non-small cell lung cancer with the normal spirometric values. FVC, forced vital capacity; FEV1, forced expiratory volume in 1 second; °FVC, postoperative change of the FVC; °FEV1, postoperative change of the FEV1.

3 FIGURE 2 Postoperative change of the FVC and the FEV1 between the lobectomy group and the segmentectomy group in patients with stage I non-small lung cancer with the airflow limitations (the FEV1% <70%). FVC, forced vital capacity; FEV1, forced expiratory volume in 1 second; °FVC, postoperative change of the FVC; °FEV1, postoperative change of the FEV1.

4 FIGURE 3 Correlation between the postoperative change of the FEV1 and the %ppoFEV1. Analysis of a linear correlation was performed with the Pearson’s correlation coefficient test. FEV1, forced expiratory volume in 1 second; %ppoFEV1, ratio of the estimated postoperative FEV1 to the predicted normal value of FEV1.
