Treating Advanced Colorectal Cancer Based on the Theory of"Yang Transforming Qi While Yin Constituting Form"
The development of colorectal cancer is based on the insufficiency of"yang transforming qi,"leading to dysfunction in the rise,fall,exit,entry,propulsion,warming,and qi transformation processes,along with impaired functions of zang-fu organs,meridians,and qi-blood circulation.This results in abnormal distribution of essence,blood,and body fluid,causing an excess of"yin constituting form,"leading to an overproduction of phlegm,blood stasis,toxic pathogens,and other turbid yin substances.The pathological nature is characterized by a combination of root deficiency and branch excess,with systemic deficiency and local excess.In the early stage of the disease,pathogenic toxins are predominant,and the deficiency of healthy qi is not yet apparent.In the advanced stages,the cancerous toxins deplete the body's qi,blood,and body fluid,often resulting in qi deficiency,yang deficiency,qi-blood depletion,or yin-yang defi-ciency,etc.Supporting yang is the foundation of treatment,as yang deficiency commonly involves the heart,spleen,and kidney.Warming and tonifying the yang of the spleen and kidney can help restore the body's function of"yang transforming qi."The yin pathogens con-tributing to colorectal cancer include dampness,phlegm,blood stasis,and cancer toxins,which should be treated by regulating qi,resol-ving dampness,drying phlegm,dissolving blood stasis,and detoxifying.However,the feasibility of relying solely on TCM to treat ad-vanced colorectal cancer is low,so it is often combined with modern medical approaches,such as chemotherapy,targeted therapy,and immunotherapy,etc.,to extend survival time and improve quality of life of patients.
