title: Genetically determined sparteine oxidation and sulfadimidine acetylation polymorphism in patients with non-occupational urinary bladder cancer.
abstract: The results of our study revealed a predominance of the percentage of extensive metabolizers (EM) of sparteine (94.8%) among 58 patients with non-occupational urinary bladder cancer in comparison with the percentage of extensive metabolizers (91.2%) in healthy persons; the difference being not statistically significant. However, among ultrarapid (EM) oxidators with the metabolic ratio (MR) < 0.5 the difference in the MR frequency distribution between 15 patients with bladder cancer (25.9%) and 18 healthy persons (11.25%) was statistically significant. Therefore, our studies provide some evidence of a possible relationship between the EM sparteine oxidation phenotype and the susceptibility to non-occupational bladder cancer. Not statistically significant slight prevalence of the percentage of slow acetylators (SA) (53.1%) among 32 urinary bladder cancer patients in comparison with the percentage of SA (49%) among 45 healthy persons may confirm the conclusion that a slow acetylator phenotype is not associated with the increased risk of the development of non-occupational urinary bladder cancer.
