Gene expression Profiles Predict Survival of Patients with Lung Adenocarcinoma [J]. Nature Medicine, 2002, 8 (8): 816-824. Of malignant tumors, the majority of patients are already diagnosed with advanced stage, and about 35% -50% of patients with stage Ⅰ recurrence after surgery. There is currently no accurate way to predict which patients may experience recurrence. Lung adenocarcinoma is a non-small cell
