对全国12个城市的13个聚氯乙烯制造工人中5459名氯乙烯作业工人和6461名对照厂工人进行了从投产到1989年12月31日为止的恶性肿瘤发病情况的回顾性和前瞻性队列调查。结果表明,男工接触组肝癌的发病率、死亡率均显著高于对照组,男性肝癌的死亡率也显著高于我国中等城市男性肝癌的死亡率。在恶性肿瘤的分类构成中,接触组男工的肝癌居首位。接触组男工肝癌的发病年龄比对照组显著提前。
A retrospective and prospective cohort of 5459 VCI workers and 6461 control factory workers from 13 PVC manufacturing workers in 12 cities across the country was put into operation from December 31, 1989 to December 31, 1989 survey. The results showed that male workers exposed to the incidence of liver cancer were significantly higher than the control group, the mortality rate of male hepatocellular carcinoma was significantly higher than the mortality of male hepatocellular carcinoma in our country. In the classification of malignant tumors, male workers in the contact group of liver cancer ranks first. The incidence of HCC in contact group was significantly earlier than that in control group.
