Objective: We report the results of our angiosarcoma of the liver (ASL) registry to assess the occurrence, the impact of exposures to vinyl chloride, and to quantify latency.

Methods: We examined more than 73,000 death certificates of North American workers employed between 1940 and 2008.

Results: We found 13 deaths of ASL among workers with vinyl chloride exposure. All 13 occurred at single plant among workers with high vinyl chloride exposure. The mean latency after first exposure was 36.5 years ranging from 24 to 56 years. No ASL deaths occurred among workers with vinyl chloride exposures after 1974, when exposures were reduced.

Conclusions: We may have seen the last case of ASL among workers exposed to vinyl chloride. Nevertheless, given the long latency of this cancer, continued surveillance seems prudent.
