The current main treatment methods for keloid scars are as follows: surgical excision, radiotherapy and stimulationWhile the radionuclide application device is mainly used in China for radiotherapy of keloid, the most common method used at present is the radionuclide application device90Sr applicator and32the P applicator is used for applying the P liquid medicine,90the Sr applicator is a public applicator, the treatment area is limited, the raw material production process is not mastered in China, and the Sr applicator can only be imported at present, so the Sr applicator has90The Sr applicator has few units, and the treatment requirements of patients are difficult to meet;32the P applicator belongs to a customized applicator, and can be supplied only once per month due to the production period arrangement of raw material production enterprises32The P medicine has higher protection requirement on the manufacturing site due to the volatilization of the radioactive medicine in the process of manufacturing the applicator, and the medicine loss is more, so the P medicine cannot be supplied in large quantity for clinical treatment. The two kinds of applicators are planar applicators, the target area for treating the keloid is set to be a plane, but almost all keloid has irregular three-dimensional structures, a cold area inevitably exists in the target area for treating the keloid, and a hot area exists in the surrounding normal skin which is intersected with the keloid due to overhigh radiation dose,90sr applicator and32the treatment depth of the P applicator is limited, the treatment for thicker keloid is weak, and in addition, the treatment lacks radiotherapy dosimetry and mainly depends on empirical dose treatment.
