Meaning of Minimally Invasive Interventional Therapy Minimally invasive interventional therapy is a modern tumor treatment method based on medical imaging, oriented by imaging technology, integrating advanced medical imaging technology, drug therapy, biological and genetic technology such as (freezing, microwave, radiofrequency ablation, chemical ablation, etc.), which has many advantages such as precise location, accurate treatment, small trauma, light pain and exact efficacy. Compared with conventional chemotherapy, this technology is not limited by the metabolic cycle of tumor cells and does not have the problem of drug resistance; compared with traditional surgery, it is not only less invasive, but more importantly, it is very repeatable, can be used repeatedly and can deal with multiple or recurrent tumor nodules, and under the monitoring of modern imaging equipment, it can also accurately conduct real-time efficacy assessment. Efficacy and Prospects of Minimally Invasive Interventional Therapy for Tumors Currently, surgery is still the first choice for early stage tumors. Minimally invasive interventional therapy is mainly used for the treatment of middle and late stage malignant solid tumors in various parts of the body that cannot be operated on surgically, and its main function is to reduce the tumor load, alleviate the patient’s pain and prolong the patient’s life. However, for some early and small malignant tumors such as small hepatocellular carcinoma and kidney cancer, according to some reports at home and abroad, the clinical efficacy is close to that of surgery, and can even achieve the effect of radical treatment. With the accumulation of experience and advancement of technology, minimally invasive treatment is expected to become the first choice of treatment for many early stage tumor patients and elderly tumor patients who are unable or unwilling to undergo surgery and cannot receive radiotherapy or chemotherapy. The cost of interventional tumor treatment The cost of interventional treatment is mainly the difference of operation compared with traditional chemotherapy, there is a certain amount of surgical fee for interventional treatment, and there is also the cost of some instruments, such as catheter and guidewire, which are now cheaper. The amount of drugs used is the same as the amount of drugs used in one cycle of traditional chemotherapy, and the chemotherapy drugs are mainly Adriamycin, mitomycin, cisplatin, 5-FU, etc., which are cheaper than traditional chemotherapy drugs. In addition, compared with systemic chemotherapy, interventional therapy has a shorter hospitalization time, because the usual hospitalization time is seven to ten days, and the total cost incurred is relatively lower. Secondly, the systemic toxic side effects of interventional therapy are less severe. The cost of follow-up treatment will also be relatively lower.
