title: [Analgesics and laxatives as risk factors for cancer in the efferent urinary tract--results of the Berlin Urothelial Carcinoma Study].
abstract: A retrospective case-control study (1990-1995), the Berlin Urothelial Cancer Study (BUS), examined analgesics and laxatives as risks for the induction of urothelial cancer in renal pelvis, ureter and bladder. Especially for renal pelvis cancer could observe substance and dose specific risk of compound analgesics. The analgesic substances Phenacetin, Paracetamol, Acetylsalicylic acid (ASA) and Pyrazolones were assessed. Besides a risk of contact laxatives (chemical or anthranoide ingredients) for urothelial cancer was found, not yet described. The highest risk shows the anthranoide plant Senna. Thus this study confirms the risk of specific analgesic ingredients and found an evidence for a new risk of contact laxatives. As both, analgesics and contact laxatives, are typical OTC--("Over the counter") products, a severe controlling is demanded and for laxatives further studies are needed.
