The acetylator phenotype in patients with urinary bladder cancer

: In 53 patients suffering from bladder cancer the acelylization phenotype was examined. The frequency of slow acetylizers (70%) was significantly higher than in the control group. The more frequently occurrence of slow acetylizers in the group with professional pollutant exposition is an important reference to a higher bladder cancer morbidity in the case of carcinogen contact. A screening of the acetylization phenotype in professions with carcinogen contact may be important in the prophylaxis of bladder cancer.
