According to document report, in the course that in large intestine cancer changes to far, the patient that has 83 ％ of 18 ％ ～ can produce liver move. And be by diagnose when the patient large intestine when cancer, the person that already had 40 ％ of 20 ％ ～ produced liver move. Be in dead at large intestine the person that there is 70 ％ of 60 ％ ～ in cancerous patient has liver to shift focus. Generally speaking, the patient that cancerous happening liver transfers large intestine if not via any cure, live on average deadline is 6 ～ only 10 months; Contrary, if transfer excision of undergo surgery of focus of a disease to liver, survival rate of 5 years can amount to the patient 50 ％ of 30 ％ ～ , return the opportunity that can gain heal even. And cancerous liver transfers large intestine the patient after art, classics again the liver that operation excision has a relapse shifts focus, its survival rate of 5 years is 30 ％ , operation effect not second at first the effect that the operation treats. Accordingly, cancerous patient should control large intestine actively illness, avoid to produce liver move, once produce liver move to want as early as possible undergo surgery cure, in order to raise survival rate.

Be in clinical on, the way that cancerous happening liver changes large intestine basically has hematic travel move, lymphatic move, abdominal cavity to cultivate standoff ministry to infiltrate 4 kinds of means, see more most with hematic travel move among them. So, does cancerous patient decide large intestine what does the method that liver changes have?

１ . Once by diagnose large intestine cancer is kitchen of the primary affection, the patient should undertake B exceeds check with CT, return when necessary but nose bile duct of the lens inside classics is draw-out and biliary antigen of the embryo that make cancer (CEA) examination. Before ① art, after art is being reached in art, undertaking B exceeds an examination is large intestine cancerous patient application is the widest, and scatheless diagnoses a method one kind. Be more than to diameter of focus of a disease 2. 0 centimeters liver transfers a patient, method of this kind of examination can make the person of 98 ％ of 95 ％ ～ gets make a definite diagnosis. Notable is, b is applied to exceed an examination to hide the patient of sexual tumour at having aptly quite in art, and be less than １ to diameter of focus of a disease centimeter patient diagnostic rate is not high however. After art is being reached before ② art, undertake CT is checked, already was applied extensively on the diagnosis that cancerous liver transfers large intestine. Current and clinical on the patient basically has the following kinds of methods when undertaking CT checks: Smooth sweep, common increase, large dose increases, scanning of the CT below arterial radiography, and scanning of the CT below portal vein radiography. Generally speaking, CT examination is less than at diameter of focus of a disease aptly quite 2. 0 centimeters liver transfers a patient, and be less than １ to the diameter. Check of 0 centimeters focus of a disease goes out rate is not high however. ③ can make through examination of cancerous embryo antigen cancerous patient gets the large intestine of 36 ％ diagnose, and check through cancerous embryo antigen after art, more significant. Consider to make clear, the diagnosis that makes through this kind of method wants videoer than passing the method that learns to reach clinical examination is early 6 ～ 8 months.

2. Liver is felt with the hand in art, the B in combining art exceeds detect.

3. Large intestine after cancerous art or the person that liver transfers future trouble of resection of focus of a disease should undertake cancerous embryo antigen, B exceeds regularly, γ - glutamic acid turns peptide is enzymatic with alkalescent phosphoric acid enzymatic (AKP) the examination that waits for a project. The patient is commonly after art １ year want every 3 months to check １ second; Want every 4 ～ the 2nd year 5 months check １ second; Want every 6 months the 3rd year to check １ second; Can check １ every year 3 years later second. The sign that discovers liver move is like in the examination, the patient should undertake the CT below portal vein radiography scans in time.

Be in clinical on, because people is common the cure rate after thinking cancerous happening liver transfers large intestine is very minor, so most patient often can abandon cure. But at present medical expert is aimed at large intestine patient of cancerous liver move is had " good " biology is characteristic, and the characteristic of cirrhosis of few and amalgamative liver, already obtained very great progress on cure. Among them the method that operation cure is first selection of this ill patient only. Besides there is lymph node inside liver move focus of a disease or liver shift focus beyond the move, liver that cannot excise number is in 4 above person, most patient all can do liver to excise an operation. Integrated home foreign language offers an analysis, the prognostic situation of the patient after the operation is as follows roughly: The survival rate that liver of ① single shot changes the patient after focus of a disease is excised 5 years is 30 ％ , the survival rate that much hair liver changes the patient after focus of a disease is excised 5 years is 13 ％ ; ② transfers the person that diameter of focus of a disease is less than 5 centimeters, the survival rate of 5 years after its art is 27 ％ , the survival rate of 5 years after its art is the person that be more than 5 centimeters 7. 5 ％ ; ③ is in the patient that large intestine is discovered to liver is transferred in cancerous surgery and excises move focus of a disease along with all the others, the survival rate of 5 years after its art is 21 ％ ; ④ adopts liver leaf excision, liver paragraph excision and the patient that liver wedge excises, the survival rate of 5 years after its art is mixed for 13 ％ , 21 ％ respectively 24 ％ . Although operation cure is large intestine,cancerous liver changes main treatment method of the patient, but patient still cannot the comprehensive treatment of oversight other, especially to cannot the patient that undergo surgery treats, adopt refrigerant, anhydrous alcohol to inject reasonably, the inject inside body of the tumour after hot cure or liver artery embolism change the method such as cure to have treatment, to improving its life quality is mixed rise live period all have certain effect. In addition, as a result of large intestine cancerous liver transfers a patient to there still is recrudescent possibility after art, the place of be put into trouble also is given priority to with liver. So, once produce this kind of situation, the patient can choose the method that the operation excises again. Because this is planted,the method still can prolong the patient's life on certain level.
