In a proportional mortality analysis of 161 deceased workers in two plants processing or producing vinyl chloride, a 50% excess of deaths due to all cancer was seen. Specific sites of cancer with the greatest excess included liver and biliary tract, lung and brain. The excess in fatal cancer was seen mainly in men who died before age 60. Also, there was a trend in time in the ratio of observed to expected deaths: since 1970 over twice as many cancer deaths as expected have occurred.
在对两家氯乙烯生产或加工工厂的 161 名已故工人进行比例死亡率分析时,发现所有癌症导致的死亡人数超出了 50%。具有最大超额的癌症特定部位包括肝脏和胆道、肺和脑。致命癌症的超额主要发生在 60 岁之前死亡的男性中。此外,观察到的死亡人数与预期死亡人数的比例随时间呈趋势变化:自 1970 年以来,发生的癌症死亡人数超出预期的两倍。
