1, do not look at the advertising to see the efficacy: the famous “heavy ion therapy” claims to have three major magic weapons to cure cancer: heavy ion high-energy rays, Bragg peak effect and respiratory gating technology; radiofrequency ablation technology actually has similar three major weapons: the best thermal efficiency, range controllability, puncture accuracy. The strongest effect of the rays is to burn, but it is impossible to make it burn, so the intensity is reduced to combat the destruction of DNA; in fact, to kill tumor proteins, 90°C is the best burn temperature, and the current technology only radiofrequency ablation can do it. Bragg peak theoretically the range can be controlled (physical factors), but the rays through a certain thickness of the body (biological factors), it is difficult to control, Bragg is ‘not lager’; multi-polar radiofrequency ablation, on the other hand, can control the front and back position by inserting and pulling the needle, and control the left and right range by opening and closing the needle, purely physical factors, very little influence by biological factors . Respiratory gating technology is to control every breath when treating tumor, treatment follows breathing, otherwise it will be hit and miss, so it is better to treat fixed position organs (head and neck), and be cautious to treat mobile position organs (chest and abdomen); radiofrequency ablation is just to let patients close their breath when puncturing and control once, and they can breathe freely after hit. Heavy ion treatment is non-invasive, improper use of the normal tissue through the rays will produce a large trauma; radiofrequency ablation is minimally invasive, only puncture needle tract damage, very small, the treatment is easy to control, do not worry about the large trauma. 2.Rational selection of indications: Heavy ion therapy is applicable to fixed organs, focusing on head and neck tumors; radiofrequency ablation is applicable to mobile organs, focusing on thoracic and abdominal solid organs such as lung cancer, liver cancer, kidney cancer, neither of which is used for cavity organs such as gastrointestinal tumors, and as far as possible not for advanced tumors. 3, have to say the cost: heavy ion bidding, Siemens offer 1.5 billion yuan, domestic offer 600 million yuan, maintenance costs 100 million per year. Exactly how much money is burned? Treatment costs 300,000, you know. Japanese heavy ion gas pedal cost 2.5 billion yuan, treating 1,000 patients per year, but also need to invest 300 million yuan in operating costs. The machine is huge, with a power of 25 million watts, consuming a staggering amount of electricity, treating less than 1 minute, to consume the equivalent of a town (8000 households). The construction of radiofrequency ablation melting equipment is similar to a desktop computer, with equipment investment of several hundred thousand yuan, a treatment cost of 1 to 20 thousand, power of 300 watts, power consumption is only 100,000 percent of the former. The cost effectiveness is obvious at a glance. 4, the best choice for Chinese cancer patients: The United States began using heavy ion gas pedals in 1970, after treating about 400 patients, it was closed in February 1993, one of the reasons “too extravagant”, the U.S. Department of Energy can not afford the operating costs alone. In addition, the U.S. found many treatment problems and became skeptical of the technology. It was predicted that there would be two ways to go with heavy ion therapy in Shanghai: half-heartedly or in a burned-out fashion. Ablation technology for the treatment of tumors has been included in the treatment specification for only 10 years and has become one of the main therapies for lung cancer, liver cancer and kidney cancer. If it is patient-centered, it will be easy to promote, if it is doctor-centered, it will be nephew playing the lantern – as usual. What do you choose?
