In 1979, Gerald Lower and colleagues published the first epidemiologic study to directly test the hypothesis that individuals exposed to aromatic amines would be at higher risk of urinary bladder cancer if they had the slow acetylator phenotype.1 Not only was the paper a landmark in the history of bladder cancer carcinogenesis, it was one of the very first efforts to study the effect of a metabolic polymorphism on risk for any cancer.
Lower began his paper1 by summarizing and integrating the empirical and conceptual basis for his hypothesis. After noting the initial observation of the bladder cancer excess among dye workers by Rehn in 1895,2 he described the key findings by investigators who had made seminal observations in the epidemiology of bladder cancer; performed the fundamental experimental studies of aromatic amine carcinogenesis; made the key clinical observations that the slow N-acetylation phenotype was associated with isoniazid neurotoxicity; carried out
