Hello! According to the clinical features, the patient belongs to stage ⅳ lung cancer. Cytological or pathological diagnosis is also needed. Followed by staging examination and organ function examination. After the data is complete, systemic treatment, including chemotherapy and/or targeted therapy, can be started. If it is small cell lung cancer, only systemic chemotherapy is considered. thank you

Dr. Li Junling solemnly reminded me that I couldn't fully understand the illness because I couldn't see the patient face to face. The above suggestions are for reference only. Please go to the hospital for specific diagnosis and treatment under the guidance of a doctor! )
