[Risk factors for urothelial carcinoma: drinking measures, smoking and other life style-related risk factors--results of the Berlin Urothelial Study (BUS)].
With the exception of smoking and several occupational exposures there is little knowledge about risk factors for urothelial cancer. A case control study in the area of former West Berlin was performed from 1990-1995 to investigate the role of several lifestyle risk factors, such as smoking, drinking behaviour and regular intake of analgesics and laxatives. The study includes 647 hospital-based incident cases with bladder cancer (n = 571), renal pelvis cancer (n = 51), and ureter cancer (n = 25), and 647 population-based controls which were matched individually by sex and age. Data analyses were carried out using standard methods for case control studies (conditional multiple logistic regression analysis). Odds ratios (OR) and 95% confidence intervals (CI) were applied as effect parameter. Statistically significantly increased odds ratios were observed for current smoking (OR: 3.46, 95% CI: 2.50-4.78), previous but now abandoned smoking (OR: 1.51, 95% CI: 1.09-2.81), and for regular intake of laxatives (OR: 2.52, 95% CI: 1.56-4.09). Furthermore, an increased risk for urothelial cancer was observed for daily consumption of three and more litres of cold drinks (OR: 2.65 95% CI: 1.12-6.24). The results underline that lifestyle factors other than smoking may contribute to a higher risk of urothelial cancer.
