We have treated ten patients with lung cancer among workers in a chromate factory between 1972 and 1976. Four further cases were also found through death certificates and medical records. Most were smokers and all were men. The average duration of exposure to chromate was 24 years (range 10 to 36). The cell type in our ten patients was squamous in seven and small anaplastic type in three. The primary sites were all in large bronchi. The incidence (person per year) calculated from the number of employees, duration of factory activity, number of cancer patients, and shortest duration of labour period among the patients was 657.9 per 100,000 compared to 13.3 per 100,000 in Japan as a whole.
1972年至1976年间,我们对一家铬酸盐工厂的10名患肺癌工人进行了治疗。通过死亡证明和病历又发现了另外4例。大多数患者吸烟,均为男性。铬酸盐暴露的平均时长为24年(范围10至36年)。我们这10名患者中,细胞类型为鳞状的有7例,小间变类型的有3例。原发部位均在大支气管。根据员工数量、工厂运营时长、癌症患者数量以及患者最短工作时长计算得出的发病率(每年每千人)为每10万人657.9例,而日本全国的发病率为每10万人13.3例。
