dc.description.abstractBACKGROUND: Smoking is a well-known carcinogen for lung cancer. However, whether smoking affects the biological behavior of lung cancer remains uncertain. This study aimed to investigate the influences of smoking intensity on the clinicopathologic characteristics of and survival in non-small cell lung cancer (NSCLC). METHODS: We retrospectively reviewed 2238 consecutive patients who underwent surgical resection for NSCLC between 1990 and 2010. Smoking intensity was defined as pack-years (PY). The patients were divided into three groups according to the median value of smoking intensity (40 PY): group A (never smokers), group B (smoking intensity less than 40 PY) and group C (smoking intensity more than 40 PY). RESULTS: There were 1629 (72.8%) male patients, and the mean age was 61.71 ± 13.17 years. Adenocarcinoma was reported in 1058 (47.3%) patients. The median follow-up period was 30.7 months (range: 0.0-261.7 months). The 5-year overall survivals for groups A, B and C were 60.1%, 51.6% and 43.2%, respectively (p < 0.001). In subset analysis by histology, the 5-year overall survival was significantly different according to smoking intensity in adenocarcinoma (p < 0.001), but there was no difference in the non-adenocarcinoma. In adenocarcinoma, the incidences of vascular invasion (p = 0.028), pleural invasion (p = 0.013) and poor differentiation (p < 0.001) were higher and tumor sizes (p < 0.001) were greater in group C than others. On multivariate analysis, smoking intensity was an adverse risk factor for overall survival in surgically treated adenocarcinoma patients (hazard ratio = 1.008, p = 0.028). CONCLUSION: Smoking intensity was an adverse prognostic factor after surgical resection of adenocarcinoma. Heavy smoking was correlated with poor pathologic characteristics in adenocarcinoma.-
