| 目的 比较关于放射性肿瘤判断的两个国家标准GBZ 97-2002(简称旧标准)和GBZ 97-2009(简称新标准)在铀矿工肺癌判断中的差异,探讨新标准对铀矿工肺癌病因判断带来的影响。方法 利用既往流行病学调查中的19例铀矿工肺癌资料,分别按照新、旧标准GBZ 97-2002和GBZ 97-2009进行肺癌的辐射病因计算。结果 对19例铀矿工肺癌的病因概率(PC)计算显示,采用旧标准,有7例判断为放射性肿瘤;采用新标准,则可能有15例被判断为放射性肿瘤,增加了1.1倍。其原因是2009年标准使用PC值的95%上限替代2002年标准以PC值的中位数作为病因概率判断值。 结论 与GBZ 97-2002相比,GBZ 97-2009判断门槛明显减低。 |

| Objective To evaluate the difference of PC values based on GBZ 97-2002 and on GBZ 97-2009 for lung cancer cases in Chinese uranium miners. Methods Using 19 lung cancer data ascertained in the past epidemiological study, PC values were calculated according to GBZ 97-2002 and GBZ 97-2009. Results In the 19 lung cancer cases, those cases that could not be judged as radiogenic cancers based on GBZ 97-2002, but may be judged as radiogenic cancers with GBZ 97-2009. The probability was enlarged by 1.1 times at least. The major reason was that the used value was the upper limit of 95% in GBZ 2009 but the median in 2002. Conclusions Compared to GBZ 97-2002, the criteria value of PC in GBZ 97-2009 drops obviously. |
