For patients with certain solid tumors that are not suitable for surgery or have lost the opportunity of surgery, minimally invasive interventional techniques can achieve satisfactory results while preserving physiological functions and quality of life. This was learned from the “National Summit Forum on the Development and Construction of Interventional Radiology Discipline”, which was held in Tianjin. The executive chairman of the conference said that minimally invasive interventional techniques aiming at preserving patients’ functions and improving their quality of life are gradually accepted by patients and doctors, and will become the main development trend. It is understood that most of the clinically diagnosed tumor patients are in the middle and late stage, only less than 20% can receive traditional surgical treatment, and most of them can only live with tumor and receive palliative treatment, and are in a situation of “helplessness” and poor quality of life. With the continuous development of medical science and technology, minimally invasive interventional tumor treatment has become one of the preferred treatment methods for middle and late stage tumors with its characteristics of mild trauma, low side effects, strong target and fast recovery, and has become the most active and promising technology in the field of comprehensive tumor treatment. The development of interventional radiology, in addition to the treatment of vascular diseases is in the treatment of liver cancer and other tumor diseases, should be said to play an increasingly important role, including the development of technology and the continuous progress of tumor drugs. Minimally invasive interventional therapy for tumors is the targeted treatment of tumors under the guidance of medical imaging, using vascular embolization chemotherapy, radiofrequency, freezing and other ablative technical methods. Different drugs are injected directly into the tumor lesions through blood vessels or through skin puncture to change the blood supply of the lesions and deprive them of the source of nutrients, thus “starving” the tumors; high concentration of anti-cancer drugs are directly applied to the lesions to “kill” the tumors; through argon-helium-freezing technology, the tumors are killed with the use of minus 140%. The tumor is “frozen” to death by argon gas at -140 degrees Celsius through cryogenic technology. The minimally invasive interventional surgery incision is only about 2 mm, which is less traumatic, less complications and faster recovery after surgery, so 80% of tumor patients can receive treatment. Experts said that for advanced prostate cancer, benign tumors such as uterine fibroids and hepatic hemangioma, they can even achieve the same effect as surgical radical treatment.
