The results of 30 years screening of exposed workers in the hard metal industry are presented in a retrospective study. There were 11 workers who had radiographic signs of pulmonary fibrosis. No correlation was found between intensity and/or duration of exposure and the stage and progression of pulmonary fibrosis. In 45% of the cases there was progression of the fibrosis after cessation of the exposure. Steroid therapy in three cases relieved the subjective symptoms but there was no regression of the fibrosis.
一项回顾性研究展示了对硬质合金行业接触工人进行30年筛查的结果。有11名工人出现了肺纤维化的影像学征象。未发现接触强度和/或持续时间与肺纤维化的阶段及进展之间存在相关性。在45%的病例中，接触停止后纤维化仍有进展。3例接受类固醇治疗后主观症状有所缓解，但纤维化并未消退。
