When we all know the emergence of body cavity perfusion treatment technology in clinical practice and the remarkable effect of this technology in treating cancer, many patients and their families are more concerned about this technology. Today, we will give you a specific explanation about the characteristics of body cavity perfusion so that more people can understand this technology. The characteristics of this new technology of body cavity infusion are that the tumor is directly immersed in the highly concentrated chemotherapy solution, which improves the ability of the drug to kill the tumor cells. The drug can be in contact with the tumor for a long time, and only a small amount enters the body circulation, which reduces the toxic side effects of the drug. Intraperitoneal infusion of chemotherapeutic drugs into the liver through the portal vein system can enhance the therapeutic effect on liver tumors. The above is the characteristics of this new technology of intracorporeal perfusion, which many people know now, and many patients are not more aware of this technology, and many patients are excited about the clinical results of this technology.
