Chemotherapy is the main method of cancer, but in the process of chemotherapy, some people are very serious and vomit after eating something, while some people can eat and drink, like they are fine. Why is there such a big difference between the same chemotherapy?
The patient, Mr. Chen, came to our hospital from Guizhou to receive "DSA visual minimally invasive arterial interventional perfusion embolization" due to nausea and vomiting, unable to eat, and could not tolerate local chemotherapy. Combined with "tumor green hyperthermia", it significantly improves the efficacy, kills tumor lesions and alleviates the suffering of the whole process, and is not guilty.
Minimally invasive interventional arterial perfusion embolization – precise and efficient tumor control
Under the guidance of DSA, a thin flexible catheter is inserted from the femoral artery or brachial artery into the blood supply artery of the lesion, and a high concentration of chemotherapy drugs is infused into the tumor, increasing the concentration of chemotherapy drugs in the tumor area, killing the cancer cells at the metastatic site through lymphatic drainage, and avoiding the disadvantages of a very small amount of drugs entering the tumor before the veins flow through the whole body.
Arterial perfusion chemotherapy is superior to conventional intravenous chemotherapy for anti-cancer, such as primary liver cancer and liver metastases, which have little effect on systemic chemotherapy, while interventional arterial infusion chemotherapy has a better effect than systemic chemotherapy.
What are the advantages of minimally invasive interventional arterial perfusion embolization?
1.Precise delivery and effective increase of local drug concentration in tumors;
2.Significantly amplify the "first-pass effect" of chemotherapy drugs and improve the efficacy;
3.from focusing on concentration dependence to paying equal attention to time and concentration dependence;
4.Local anesthesia, small trauma, and the surgical opening is only 2 3 mm puncture opening;
5.Adverse effects were milder than those of systemic chemotherapy.
Hyperthermia for tumors – the "green sensitizer" of chemotherapy
Heat the tissue to a temperature that kills tumor cells (42.)5 or more) and maintain it for a certain period of time, taking advantage of the difference in temperature tolerance between normal tissues and tumor tissues, to achieve the effect of killing tumor cells without damaging normal tissues.
Because high fever does not damage normal tissues when killing cancer cells, it will not cause adverse reactions such as bone marrow suppression, hair loss, etc., and will not cause any pollution to people and the environment, so hyperthermia is known as the "green**" of tumors
When hyperthermia and chemotherapy are combined, it accelerates blood circulation, dilates blood vessels, increases the number of chemotherapy drugs entering tumor cells, enhances the killing effect of chemotherapy drugs on tumors, and adds that hyperthermia itself has a high-temperature killing effect on tumors.
In addition, because hyperthermia has such an obvious synergistic effect on chemotherapy drugs, the dose of drugs can be reduced on the original basis, the efficacy can be improved, and the toxicity of chemotherapy drugs can be reduced, and the symptoms of patients can be improved, and the quality of life can be improved.
