Gastric cancer patients with radiotherapy treatment (b) of the skin reaction
The amount of radiation tolerance of the skin with the use of radioactive sources, size and location on irradiation. Treatment of 60 drilling machines and linear accelerators and high energy X- ray penetration, the skin by a small amount of reaction to light; X ray treatment machine produced by low energy X ray and electron beam accelerator induced by the large amount of skin reaction weight. Skin reactions is divided into three degrees:
I degree of reaction: erythema, a burning and itching feeling, to irradiation by the bright red skin, fade to dark red, after a scaling, said dry response.
Grade reaction: a high degree of congestion, edema, blister formation, there is exudate, erosion, said the wet reaction.
degree of reaction: the formation of ulcers or necrosis, invasion to the dermis, resulting in radiation injury is difficult to heal. A few days after radiation exposure or more parts, there may be skin atrophy, telangiectasia, lymphatic drainage barrier, edema, and dark brown spots, pigmentation, called the late response.
Radiation field of skin protection measures:
