Image-Guided Video-Assisted Thoracoscopic Resection of Small Peripheral Lung Nodules

摘要

Lung cancer is the most common cause of cancer death for both men and women in the industrialized world. Small-cell lung cancer accounts for about 25% of lung cancers and is usually widespread by the time it is first seen. The remaining 75% of lung cancers are collectively termed non-small-cell lung cancers. When presentation is by symptoms or incidental discovery, about 50% to 60% of non-small-cell lung cancers are parenchymal nodules or masses, and 40% to 50% are bronchial or hilar. More than 50% of patients with non-small-cell lung cancer will have distant metastases at the time of diagnosis, and only 25% will have potentially resectable disease that can be cured. The overall survival rate at 5 years for lung cancer is approximately 15% and has not significantly improved over the last several decades.
