A cross-sectional mortality study of 4,341 deaths occurring among current and former employees of 17 PVC fabricators during 1964-1973 is presented. The objectives are: (1) to identify any angiosarcoma deaths among the employees of these fabricators, and (2) to examine the distribution of deaths by cause. No angiosarcoma deaths were found among the study group. Sex-race-cause-specific Proportionate mortality Ratios (PMR's) were computed, using the corresponding U.S. mortality as the standard. Among white employees, there appears to be an excess in total cancer mortality, particularly that of the digestive system. Observed deaths were found to exceed the expected in cancers of the breast and urinary organs among white females. Deficit mortality was observed in cirrhosis of liver among both male and female white employees.
本文呈现了一项横断面死亡率研究，该研究针对1964年至1973年间17家聚氯乙烯制造商的在职和离职员工中发生的4341例死亡病例。研究目的如下：（1）确定这些制造商员工中是否有血管肉瘤死亡病例；（2）按病因检查死亡分布情况。研究组中未发现血管肉瘤死亡病例。以相应的美国死亡率为标准，计算了性别-种族-病因特异性比例死亡率（PMR）。在白人员工中，总癌症死亡率似乎过高，尤其是消化系统癌症死亡率。在白人女性中，观察到乳腺癌和泌尿器官癌症的死亡人数超过预期。在白人男性和女性员工中，肝硬化的死亡率均低于预期。
