Lung metastases generally cannot be completely cured, and patients with good therapeutic effects are able to prolong the survival period and improve the quality of survival to a certain extent. When lung metastasis occurs, it suggests that the patient’s condition belongs to the advanced stage, and the efficacy of surgery is affected by many factors, and the longer the interval between the resection of primary tumor and the appearance of metastasis, the better the prognosis. The treatment is mainly based on the comprehensive therapeutic measures of chemotherapy, targeted drugs, immune drugs, local therapy and other methods combined. The main purpose of comprehensive treatment for lung metastases is to reduce clinical symptoms such as cough, chest tightness, shortness of breath, dyspnea, etc. If the treatment effect is good, the lung metastases can be shrunk or stabilized, and the survival time of the patients will be prolonged, but it is difficult to cure them completely. It is suggested that patients with lung metastases should go to regular hospitals as soon as possible and listen to the advice of professional doctors.
