What is the CyberKnife?

May 26, 2016

Over the years we have always been entrenched in cancer mortality in Taiwan first place, while most of [liver] and [lung cancer] turns the first! Liver cancer, for example, the past treatment of choice is usually surgery, but really suitable for surgery patients, but only about two percent, because most of the patients found to have advanced cancer when is the last that she has cancer, this time due to poor liver function Surgery increase the risk of surgery. Other therapies include liver arterial chemoembolization, radiofrequency ablation, alcohol injection. According to foreign data show that cancer patients in Liucheng need to receive radiation treatment in surgery, both for early cancer, unresectable liver cancer, liver cancer cause of portal vein thrombosis, or with the use of transcatheter arterial chemoembolization have good results . This number can not surgery, unable to accept the traditional liver cancer therapy or conventional therapy ineffective liver cancer is nothing more than a better news!


Radiation therapy sector development has centuries of history, 20 years of rapid development of the field of radiotherapy. In recent years, radiation therapy and surgery in Taiwan have introduced several of the "knife" photon knives, spiral knives, sharp-speed knife, gamma knife blade to the computer, and wherein the treatment of lung cancer [liver] and [] again CyberKnife radiosurgery is one of the best precision weapon. The so-called surgery that is the use of radiation therapy to radiation irradiated tumor ablation of tumor cells caused the necrosis; such as CyberKnife is the high-energy electron acceleration unit, make energy conversion stimulate radiation, and then to more X-ray incident angle of irradiating cancer, so radiation can destroy Huanglong, the complete elimination of the cancer cells in vivo. As to why the called the "knife"? This is because the earlier the only way to deal with the use of surgical removal of the tumor, and radiation has the same function since, with the difference a "real knife" one with "radiation knife", both of which will be in vivo tumor removed from the patient, it is also Some of this radiation device to "knife" to get used to name, but "radiation knife" is not going to cause patients to bleed or cause pain, no pain during treatment, and this is a major feature of radiation therapy.

CyberKnife treatment for the patients, the use of high-speed computer controlled targeting system to the patient's 3D stereoscopic orientation guided throughout the immediate detection and tracking of tumor location. When the system finds the target tumor moves, the robot will be synchronized automatically corrected, to achieve true "to kill tumor target therapy." CyberKnife CyberKnife first prototype in 1994 at Stanford University formally installed attached to hospitals, mainly for the treatment of brain tumor patients. The experts at Stanford University in the continuous improvement in all areas, in 2001 formally approved by the FDA can be used in various parts of the body of cancer treatment, but also the world's first use a robotic arm to perform image-guided stereotactic radiosurgery equipment. As of 2015, there were already hundreds of hospitals CyberKnife CyberKnife to treat cancer patients, treated patients had more than thirty million people, Taiwan's number of people receiving treatment has more than thousands of people!

And 2015/8/4 is a new milestone in Taiwan's cancer treatment, the introduction of a new store Cardinal Tien Hospital, the sixth generation of CyberKnife system, this latest reform function of a computer tool to shake the whole field of radiotherapy, because although past CyberKnife with the precision and the projected radiation therapy can simultaneously track tumor movement in the name, but can not always treated large tumor, but the sixth generation of the new device is equipped with a knife so that the computer can not only treat the tumor more irregular shape, and as with previous generations precision; when not drawn out waste, go to the hospital every day up to 6-7 weeks of traditional radiation therapy, and no invasive trauma of traditional surgery, the robot arm CyberKnife treatment has been widely accepted by the medical community, Cardinal Tien Hospital Zhang Director expressed its previous 2007 starts at Tri-Service General Hospital, many cases of the use of CyberKnife experience shows that a year after the completion of treatment tumor control rate of ninety percent, the effect is quite good, but the majority of patients with mild side effects, and computer knife treatment of liver cancer and lung cancer at the beginning of February this year, has also been included in the scope of reimbursement, subject to prior assessment of compliance with payment standards.
