An epidemiological case-control study of bladder cancer in males from a predominantly rural district.
A case-control study was performed on 165 male bladder cancer patients and an equal number of male control persons matched in age and geographic area. Thirty determinants of assumed importance were examined. A multivariate logistic analysis was performed. A significant increment in the relative risk (RR) for bladder cancer was associated with cigarette smoking (RR = 1.89), a history of prostatic surgery (RR = 2.38), nocturia (RR = 2.05), previous venereal disease (RR = 2.42), industrial work (RR = 1.82), work with oil or gasoline (RR = 2.71) and work with various unspecified chemical materials (RR = 1.58).
