摘要

OBJECTIVES—To study cancer morbidity patterns in concrete workers.
METHODS—A cohort of 33 503 concrete workers was enrolled in the study from 1971-86. The average duration of follow up was 19.4 years (582 225 person-years). The workers' cancer morbidity was compared with the morbidity of the general population.
RESULTS—A total of 3572 incident cancers were observed. Significantly increased standardised incidence ratios (SIRs) were found for all malignant neoplasms (SIR 107; 95% confidence interval (95%CI) 103 to 110), cancer of the lip (SIR 179; 95%CI 134 to 234), cancer of the stomach (SIR 139; 95%CI 122 to 158), cancer of the lung (SIR 125; 95%CI 114 to 137), and cancer of the prostate (SIR 108; 95%CI 101 to 116). Reduced risk was found for cancer of the large intestine (SIR 80; 95%CI 69 to 93) and cancer of the testis (SIR 50; 95%CI 26 to 87). Smoking was more prevalent among the concrete workers than in the general population (50% v 35%).
CONCLUSION—The study has shown a slightly increased overall risk of cancer among concrete workers. The increased risk of lung cancer could entirely be due to differences in smoking habits between concrete workers and the general population. There is a possibility that the smoking also has contributed to the increased risks of stomach cancer and lip cancer, but occupational factors may have contributed to these cancer sites.

方法-从1971-86年开始，共有33503名混凝土工人参加了该研究。平均随访时间为19.4年（582225人年）。将工人的癌症发病率与普通人群的发病率进行比较。
结果-总共观察到了3572例癌症。发现所有恶性肿瘤（SIR 107; 95％置信区间（95％CI）103至110），唇癌（SIR 179; 95％CI 134至234），恶性肿瘤的标准发生率（SIR）显着增加胃癌（SIR 139; 95％CI 122至158），肺癌（SIR 125; 95％CI 114至137）和前列腺癌（SIR 108; 95％CI 101至116）。发现大肠癌（SIR 80; 95％CI 69至93）和睾丸癌（SIR 50; 95％CI 26至87）的风险降低。在混凝土工人中，吸烟比在普通人群中更为普遍（50％对35％）。
结论—该研究表明，混凝土工人中患癌症的总体风险略有增加。罹患肺癌的风险增加完全归因于混凝土工人与一般人群之间吸烟习惯的差异。吸烟也可能导致胃癌和唇癌的风险增加，但职业因素可能导致这些癌症部位。
