[Objective]To summarize professor CHENG Haibo's clinical experience in treating tumor metastasis with cancerous toxin pathogenesis theory. [Method] By following the teacher clinic and sorting out the related cases,the author summarizes professor CHENG Haibo's academic experience of treatment of tumor metastasis with cancerous toxin pathogenesis theory,and for proven cases. [Result] On the base of cancerous toxin pathogenesis theory and clinical practice,Professor CHENG Haibo puts forward that deficiency of vital qi and cancerous toxin inflowis the basic pathogenesis of tumor metastasis.
