For children, the side effects caused by the radiation are more severe compared to adults. Therefore, proton treatment will be helpful in this case. For adult patients, the head, neck and retroperitoneal areas can have a very limited radiation dose due to the distribution of major organs around these areas. In this case, the proton treatment can transfer a relatively higher radiation dose while preventing the increase of the side effects which may occur in the important organs of the facial area (including eyes, ears, and brain) and abdominal areas (stomach, duodenum, intestine tenue, liver, and kidneys).

[Proton Therapy compared to the X-ray treatments to treat sarcoma]

In the case of pediatric sarcoma, it is reported that proton treatment can maintain a similar efficacy compared to the existing X-ray treatments and decrease the acute or sub-acute side effects, as well as decreasing the secondary cancer occurrence rate.

Particularly, this treatment can safely transfer a high radiation dose to the retroperitoneal sarcoma, well-known for a 50% or more recurrence rate to be expected within 5 years due to the insufficient radiation transfer, and it is reported that the tumor control rate for 5 years is more than 90%.
