| Research Abstract |
We reviewed the mechanism of lung cancer from COPD. In the inflammatory micro-environment, bronchial epithelium and alveoli are destroyed. During the repair of these injured cells, broncho-alveolar stem cells (BASC) are activated and genetic mutation was introduced to lead carcinogenesis. In this phenomenon, activation of signal transducers, such as NF-kB and STAT3, are induced and contributed to carcinogenesis. We collected clinical data of approximately 1400 lung cancer patients who received surgical resection, and classified into four groups of COPD severity according to preoperative spirometry. Non-COPD and mild COPD patients had more adenocarcinomas, whereas moderate to severe COPD patients had more squamous cell carcinomas.
We conducted COPD screening by using community-based lung cancer screening program. Approximately 4% of attendance were suspected COPD and 25% of these were diagnosed COPD by spirometry.
