Abstract

Surgical resection is the treatment of choice for tracheal and bronchogenic carcinoma. However, there are several inoperable cases because of poor performance status due to severe tumor invasion, or aging.On the other hand, an increasing number of early-stage lung cancer cases is being detected as a result of improved survey and diagnostic techniques. In patients with limited pulmonary function, it would therefore be beneficial to reduce the extent of resection, thereby preserving pulmonary function.Patients with severe respiratory distress, immediate Nd-YAG laser therapy and/or stenting is the first choice to improve their performance status, and PDT provides an alternative to surgical resection as the primary treatment for patients with early-stage central-type lung cancer.Considering the quality of life of such patients, the role of conservative treatments such as laser therapy, brachy therapy and stenting are discussed in this paper.
