目的通过对张家港市1980年前从事放射工作人员肿瘤流行病学调查结果进行分析,旨在为放射性疾病的防治提供依据。方法采用病例对照的方法,通过问卷调查,探索该市从事放射工作人员的肿瘤的发生及死亡情况与射线接触的关系。结果放射组和对照组肿瘤发生率及死亡率没有统计学上的差异(P>0.05)。总体上,由于接触放射因素,使得放射组肿瘤和死亡发生的危险性提高;按照性别分层,使得男性肿瘤和死亡的危险性会增加;按照年龄分层,在对照组人群中,≤69岁者肿瘤及死亡的发生危险性较高,而放射组人群≤69岁者死亡发生的危险性较高,>69岁的肿瘤发生的危险性较高。结论由于接触放射因素,使得放射组肿瘤发生和死亡发生的危险性都较对照组高。
Objective To analyze the epidemiological results of oncology of radiation workers in Zhangjiagang City before 1980 so as to provide basis for the prevention and treatment of radiation diseases. Methods A case-control method was used to investigate the relationship between the incidence and mortality of radiation workers and radiation exposure in the city through questionnaires. Results There was no significant difference in tumor incidence and mortality between radiotherapy group and control group (P> 0.05). In general, the risk of radiation-induced tumorigenesis and death increased due to exposure to radiation; the risk of cancer and death in men increased according to gender stratification; by age, in the control group, ≤69 The risk of cancer and death is higher, while the risk of death in patients ≤69 years old in radiotherapy group is higher, and the risk of tumors> 69 years old is higher. Conclusion Due to exposure to radioactive factors, the risk of tumorigenesis and death in radiotherapy group is higher than that in control group.
