Bronchoscopic, photodynamic, and laser diagnosis and therapy of lung neoplasms.

The use of lasers in the diagnosis and treatment of lung neoplasms has just surpassed a 20-year experience. This paper reviews recent developments in the use of lasers in the palliative treatment of advanced tracheobronchial tumors and pleural mesothelioma. The role of bronchoscopic laser therapy relative to other endobronchial treatment modalities such as stent placement and brachytherapy is presented. Finally, the potential use of lasers in photodetection and curative treatment of early lung cancer is discussed.
