Lung cancer, one of the most important cancers in the spectrum of malignancies, is diagnosed in more than 500,000 new cases worldwide each year, and the mortality rate of lung cancer in China is also rising rapidly, reaching 20.41 per 100,000 in the 1990s. For this tumor with increasing incidence, despite the large amount of human and material resources invested in research, unfortunately, the treatment effect has been unsatisfactory, and comprehensive treatment still cannot solve the problem of tumor recurrence and metastasis. Internationally, improvement of survival quality and prolongation of survival time have been included as an important indicator in the evaluation criteria of tumor efficacy. Clinical studies have shown that TCM has obvious advantages in improving the survival quality and prolonging the survival time of tumor patients by comprehensively regulating the body’s internal environment and balance and helping to re-establish the body’s tumor control function. In the long-term clinical practice of lung cancer treatment, we are guided by TCM theories and adopt the principle of TCM evidence-based treatment, i.e. the principle of supporting the righteousness as the primary treatment and eliminating the evil as the secondary treatment, i.e. according to the different types of evidence manifested by patients’ endowment, yin and yang of the body, different internal organs of deficiency of the righteousness, and different reactivity of the body, we carry out evidence-based treatment. For those with deficiency of yin and yang, yin is nourished to warm the kidney; for those with deficiency of qi, phlegm and dampness, qi is benefited to strengthen the spleen, etc. The main objective is to support and cultivate the root and adjust the balance of imbalanced yin and yang. 2.Significant improvement of symptoms, improvement of living status, and stabilization and increase of body weight mostly. 3.Improve the immune function of advanced lung cancer patients, especially improve the function of immune active cells. 4.Relieve and stabilize the lesions. 5.Cooperating with surgery can promote the recovery of the body after surgery, and combining with radiotherapy can reduce the toxic side and increase the efficacy of radiotherapy. Therefore, TCM must be used throughout the whole process of lung cancer treatment, and the earlier the patient receives TCM treatment, the better the effect will be. At the same time, since most lung cancer patients are physically weak and their positive energy is damaged, if Chinese medicine treatment can be combined with the patient’s physical condition and evidence, and if the patient can reasonably choose medicinal food, i.e. “dietary supplement”, it can increase the patient’s nutrition, and synergize with Chinese medicine to promote the restoration of the balance of yin and yang of the body and enhance the ability to resist disease, thus improving the patient’s life quality and treatment effect. This can improve the quality of life and treatment effect. 1.
