以三个工厂３ ２７９名铸钢、铸铁工为暴露组， 以同厂１ １７６ 名机加、修机工为非暴露组， 对１９７２ 年１ 月１ 日在册的队列成员进行了回顾性队列研究。观察期自１９７２ 年１ 月１ 日至１９９２ 年１２ 月３１ 日。结果表明， 铸造工肺癌粗死亡率４６－４４／１０ 万， 占恶性肿瘤死亡的３０－１０ ％ ， 在恶性肿瘤死亡中居首位。以一般人群作参比标准时， 铸工标化死亡比（Ｓｔａｎｄａｒｒｉｚｅｄ Ｍｏｒｔａｌｉｔｙ Ｒａｔｉｏ， ＳＭＲ） 为１－５６ ， １－８３ （ Ｐ＜ ０－０５）。男性尘肺患者肺癌死亡率高于男性非尘肺患者， ＳＭＲ 为２－１５ （χ２ ＝ ６－９２） ， 相对危险度（ＲＲ） 为３－４０ （χ２ ＝ ６－９６） ， 年龄分层处理后总的相对危险度（Ｒｅｌａｔｉｖｅ Ｒｉｓｋ Ｔｏｔａｌ ＲＲＴ） 为１－６９ （χ２ＭＨ＝ １－１９）。结果表明，该队列铸造工肺癌死亡超量， 尘肺患者尤为明显。
A retrospective cohort study was conducted on 3,129 cast steel castings and cast iron workers in the three factories for the exposure group and 1 176 mechanized and mechanized repair workers in the same plant as the non-exposed group on January 1, 1972. . Observation period from January 1, 1972 to December 31, 1992. The results showed that the rough death rate of foundry lung cancer was 46-44 / 100000, accounting for 30% -10% of the deaths of malignant tumors, ranking first in the death of malignant tumors. With the general population as a reference standard, the Standarrized Mortality Ratio (SMR) was 1-56 and 1-83 (P <0-05). The mortality of lung cancer patients with male pneumoconiosis was higher than that of male patients with non-pneumoconiosis, the SMR was 2-15 (χ2 = 6-92) and the relative risk (RR) was 3-40 (χ2 = 6-96) Relative Risk Total RRT was 1-69 (χ2MH = 1-19). The results show that the cast iron foundry lung cancer deaths are particularly evident in patients with pneumoconiosis.
