Traditional Chinese medicine (TCM) thinks highly of Zheng Hou in the treatment of lung cancer. Zheng is evidence. Hou is clinical manifestations. After obtaining information and evidence of patients by means of the four diagnostic methods, doctors treat patients by syndrome differentiation. In TCM, the collection and study of medical literature of tumor are emphasized. Medical classics and successful treatment of certain cases are used to guide clinical treatment. Such practice of TCM is similar to that of evidence-based medicine (EBM). Oncology of TCM and EBM are all of ancient origin. There are many clinical reports of satisfactory curative effects in treating lung cancer by TCM. But there are still many problems in methodology, such as careless random method, incomparability in base line, and deficiency of large exponent, multicenter, blind method or randomization. Sometimes the effects of control drugs are incredible. The determination of near effect is not strict. There are exponent errors in statistics of near effect (CR+PR). Certainly, treatment of lung cancer by TCM has its uniqueness. The main characteristic of treatment by TCM is that it can restrain or slow the growth of tumor. At the same time, physical signs, symptoms and quality of life can be improved, and survival period is prolonged. "Survival rate is the golden standard". If we can explore a new treatment strategy to control the growth and metastasis of advanced NSCLC and prevent relapse and metastasis of earlier period or metaphase NSCLC by the method of binding TCM and west medicine under the rules of EBM, such as multicenter (TCM hospital and western medicine hospital),blind method, strict randomization and control, the conclusion of the study will be more scientific.
