1.Enhance chemotherapy sensitivity: High temperature can destroy the stable state of cell membrane and increase the permeability of cell membrane, thus increasing the absorption and permeation of drugs into cells and making it easier for chemotherapy drugs to enter cancer cells to kill them; 2.Lower the amount of chemotherapy drugs: Intraperitoneal perfusion chemotherapy makes the organs in the abdominal cavity directly immersed in highly concentrated chemotherapy solution, which improves the ability of chemotherapy drugs to kill free cancer cells and tiny metastases. 3.Reduce the damage of the body: anti-cancer drugs are absorbed into the portal vein through capillaries and lymphatic vessels and flow into the liver, and the detoxification effect of the liver reduces the toxic side effects of intravenous drug administration and the damage of chemotherapy drugs on normal tissues of the body; 4.Improve the immunity of the body: the decomposition products of tumor cell degeneration and necrosis after heat therapy and the large amount of heat shock protein (H The decomposition products of tumor cell degeneration and necrosis and the large amount of heat shock protein (HSP) produced by tumor cells after heat therapy can stimulate the immune system of the body to produce immune response and induce strong immune effect of T cells, which can enhance the anti-tumor immune function; 5. According to foreign statistics, the pain relief rate can be as high as 90%; 7.
