How long can a patient with advanced lung adenocarcinoma live before it metastasizes throughout the body?

The survival time of patients with advanced lung cancer cannot be determined clearly, as it depends on the patient's physical condition, the degree of disease progression, and the treatment method chosen. Lung cancer is the most common malignant tumor of the respiratory system. The survival time of patients with locally advanced lung cancer without distant metastasis is generally more than 5 years. With the continued development of chemotherapy, targeted therapy, and immunotherapy, the survival time is gradually extended. The survival time of patients with advanced lung cancer without metastasis cannot be determined.
