  1. Anti-p53 antibodies in sera of workers occupationally exposed to vinyl chloride.

    Article - En anglais


    The objective of this study was to determine the prevalence and time of appearance of serum anti-p53 antibodies during the pathogenesis of ASL associated with occupational exposure to vinyl chloride.


    Enzyme-linked immunoassay (EIA) was used to detect anti-p53 antibodies in 148 serum samples from 92 individuals occupationally exposed (in France or in Kentucky) to vinyl chloride ; 15 of these individuals (six from France and nine from Kentucky) had ASL.

    A subset of coded EIA-positive and EIA-negative sera was further analyzed for anti-p53 antibodies by immunoblotting and immunoprecipitation.

    Nucleotide sequence analysis of exons 5-8 of the p53 gene was conducted on ASL DNA from six patients.

    We tested sera from 31 men who had no occupational exposure to vinyl chloride ; they made up the control group.

    Statistical analyses were done using the Kruskal-Wallis chisquared approximation and the Wilcoxon two-sample test for normal approximation.

    All P values result from two-sided tests.


    Fourteen serum samples (from nine individuals) were positive in the EIA.

    Conclusions and Implications 

    Serum anti-p53 antibodies can predate clinical diagnosis of certain tumors, such as ASL, and may be useful in identifying individuals at high cancer risk, such as workers with occupational exposure to vinyl chloride.
