[Occupation and tobacco as risk factors in urinary bladder cancer].
A case-control study among 100 male and 39 female invasive bladder cancer patients (greater than or equal to pT2, G3 & pT1) and equal number of age- and sex-matched superficial bladder cancer patients (G1 or G2, pTa) and hospital control patients was conducted in order to analyze the influence of occupation and tobacco consumption. All patients were admitted at the Department of Urology in the Kyoto University Hospital between 1975 and 1987. There were no significant risk factors among occupations in bladder cancer except housewife in female. Cigarette smokers of both sexes were at higher relative risk than non-smokers and a significant dose response relation was observed for increasing cigarette consumption.
