What are the advantages and disadvantages of cyberknife compared with traditional radiotherapy?
I participated in the design and treatment of cyberknife in radiotherapy department of a well-known tertiary hospital in China, and said some of my opinions. First of all, the cyberknife has a small indication range, the machine is expensive and the maintenance is troublesome. Under the condition of the same prescription dose, the single dose of cyberknife is much larger than that of conventional accelerator, so it is very risky and it is difficult for many hospitals to obtain permission. Of course, the side effects suffered by patients after a single treatment are much greater. Cyberknife is charged according to the treatment field, and the price of the whole treatment is several times that of the conventional accelerator. Cyberknife has a good effect on small and regular lesions, and can also control the error in a small range. The collimator can be replaced according to the size of the target area, and the low dose area can be well controlled. These are his strengths. The disadvantage is that the single treatment takes a long time, which is not suitable for some patients with great physical reaction, such as pain and cough.
