The survival time of small cell carcinoma patients is related to the physical quality of patients, the presence of other complications, the presence of other major organ damage, as well as the age of patients and the stage of small cell carcinoma, which cannot be generalized. Among lung cancers, small cell carcinoma is the most malignant and its biological characteristics are different from other lung cancers. Bloodstream or lymph node metastasis can occur when the lesion is very small, and it often shows neuroendocrine symptoms that affect the patient’s metabolism, such as intractable low sodium. Generally, stage I and II small cell lung cancer can be treated by surgery or radical radiotherapy. Small cell lung cancer can be cured by surgery and radical radiotherapy, and patients can obtain a longer survival period. In case of intermediate and advanced stage small cell lung cancer, the prognosis is usually poor, and patients usually have a survival period of 1-3 years, or even shorter 2-6 months. In addition, Chinese medicine is very effective in treating lung cancer, prolonging the survival period and improving the quality of survival, so patients can have a combination of Chinese and Western medicine.
