This study is a comprehensive explanation of Prof. Tao Guangzheng’s experience in syndrome differentiation and treatment variation of tumors. Prof. Tao devised the five principles of TCM treatment of tumors based on his clinical experience. First

reinforcing healthy qi and dispeling pathogen are the primary rule

and the ratio of the two methods should be adjusted in a dynamic balance according to the patient’s physical conditions. Second

harmonizing yin and yang is the next most important task

the aim of which is to make sure yin is calm and yang is sound

and that yang can better play the leading role in normal life activities

so that yin and yang are interdependent and mutually beneficial. Third

it is necessary to restore the free flow of qi and blood

regulate the spleen and stomach

mediate the middle

jiao

and make the ascending and descending of qi smooth and well-regulated. Fourth

the attacks on the pathogen should not be excessive. Desirable results can only be achived with accurate syndrome differentiation and treatment variation. Fifth

emotional and dietary maintenance are key

both of which are also important factors affecting the progress of the disease. The combination of these five method and the combination of syndrome differentiation and disease differentiation has important value for the prevention and treatment of tumors and the recovery of the patients. It is also of great significance for the improvement of the clinical efficacy of traditional Chinese medicine in the treatment of tumors.
