In this study, the investigators will collected all lung cancer patients diagnosed in Shanghai Pulmonary Hospital from 2012 to 2020. By conducting this population based study, the investigators would like to delineate changes of characteristics of lung cancer in Chinese patients during these years. Meanwhile, the investigators will compare clinicopathological features, routine blood tests, blood biochemical tests and coagulation status among participants at different stages. This comparing will assist the investigators to understand systemic changes during lung cancer progression. The same comparison will also be conducted among participants having different driver mutation through which the investigators will further understand the characteristics of different patients and treat patients more precisely.
This study is a single-center, real-world and large-population-based retrospective study. In the current study, the investigators not only describe the changes of demographic and basic clinicopathological characteristics of lung cancer during recent years but delineate the correlation between clinicopathological features and common clinical blood tests in such a large population.
