低能量的放射性照射常用于一系列良性皮肤病的治疗。有时因未考虑总的照射剂量,经过20～30年的潜伏期后,在治疗部位可发生皮肤癌。有报道,患放射性皮肤癌病人最重要的危险因素是总的射线聚积量,并发现面部引起慢性放射性皮炎的射线剂量较手部低。皮肤癌潜伏期的长短,同接受放射线照射的剂量成反比。本文对76例良性疾病患者应用小剂量放射治疗引起的慢性放射性皮炎发生肿
Low-energy radioactive radiation is often used in the treatment of a range of benign skin diseases. In some cases, skin cancer may occur at the treatment site after a latency period of 20 to 30 years due to failure to consider the total irradiation dose. It has been reported that the most important risk factor for patients suffering from radiation skin cancer is the total amount of ray accumulation, and it is found that the dose of radiation causing facial radiation dermatitis is lower than that of the hand. The length of the skin cancer incubation period is inversely proportional to the dose of radiation. This article describes the occurrence of chronic radiation dermatitis due to low-dose radiation therapy in 76 patients with benign disease.
