To summarize LI Bofan’ s clinical experience in treating large intestine cancer. It is believed that in the clinical treatment of large intestine cancer

a staged dynamic diagnosis and treatment view should be established

with three stages

three methods and nine syndromes as the main dynamic differentiation and treatment. At the same time

it is advisable to combine modern medicine with traditional medicine in a timely manner to divide large intestine cancer into early

middle（postoperative） and advanced stages. Nine syndromes includes internal blockade of heattoxicity

dampness-heat accumulation

intermingled phlegm and stasis

qi deficiency and dampness obstruction

spleen deficiency and liver hyperactivity

incoordination between heart and kidney

yang deficiency of spleen and kidney

yin deficiency of liver and kidney

as well as qi and blood deficiency. The three methods of relieving accumulation and resolving masses

strengthening vital qi and detoxification

as well as reinforcing qi and nourishing blood should be applied. A humanistic view is implemented throughout the diagnosis and treatment.
