对我院近20年来诊治的22例职业性慢性放射性皮肤损伤病例进行总结分析。结果显示,22例均为男性,放射诊断医师2人,骨科医师20人,放射作业工龄6～46年,估算手部累积吸收剂量为39.1～233.7 Gy,确诊为慢性放射性皮肤损伤Ⅰ度1例,Ⅱ度6例,Ⅲ度15例,皮肤损伤Ⅲ度合并放射性皮肤癌5例。提示慢性放射性皮肤损伤有一定的潜伏期,存在剂量-效应关系。长期不愈的放射性溃疡或角质增生物是皮肤癌变的基础。
22 cases of occupational chronic radiation-induced skin lesions treated and treated in our hospital for nearly 20 years were summarized and analyzed. The results showed that 22 cases were male, 2 radiologists, 20 orthopedic surgeons and 6 to 46 years radiotherapy. The cumulative absorbed dose was 39.1 ~ 233.7 Gy, and 1 patient was diagnosed as chronic radiation-induced skin injury , Ⅱ degree in 6 cases, Ⅲ degree in 15 cases, Ⅲ degree skin lesions combined with radiation-induced skin cancer in 5 cases. Prompted chronic radiation injury of the skin has a certain incubation period, there is a dose-effect relationship. Long-term healing of radioactive ulcers or keratinocytes is the basis of skin cancer.
