Objective  To analyze the clinical and pathological features of lung cancer with metastasis, explore the regularity and characteristics of the location of metastasis, and provide reference for future clinical treatment. Methods  A total of 658 patients with lung cancer treated in West China Hospital of Sichuan University from January 2008 to December 2014 were enrolled in this study. The effect of different clinical and pathological characteristics on different locations of metastasis was analyzed by χ2 test and logistic regression. Results  Adenocarcinoma was the main pathological type (342 cases, 52.0%), and bone (150 cases, 22.8%) and pleura (118 cases, 18.0%) were the most common distant metastasis. Compared with patients with no corresponding metastasis, patients with age <60 years took bigger proportions in patients with bone, brain and mediastina metastasis ( P<0.05). Furthermore, logistic regression analysis showed that the younger patients were more likely to have brain metastasis (P=0.024). Besides, the elder patients were more common in those with liver metastasis (P<0.001). The proportion of males was higher in the patients with lymph node metastasis than those without lymph node metastasis (P=0.010); however, the proportion of females was higher in patients with bone or pleural metastasis than those without bone or pleural metastasis (P<0.05). There was no significant difference in gender among patients with brain, lung, liver, adrenal and mediastinal metastases (P>0.05). Conclusions  Bone and pleura are the most common sites of metastasis of lung cancer. The age structure of brain metastasis tends to be younger.
