Changes in the Surgical Treatment Strategies for Nonsmall Cell Lung Cancer in the Past 20 Years: A Single-Center Experience.

This study demonstrates an improvement in long-term outcomes following lung cancer surgery with an increasing rate of surgical procedures in the last 10 years. There was an increase in the proportion of females affected and the rate of adenocarcinoma. However, the pneumonectomy and postoperative N2 disease rates have decreased with advancing preoperative evaluation techniques and parenchyma-saving surgical methods. Postoperative mortality has decreased, and the survival rate has increased.
