Occupation and cancer of the lower urinary tract.

Cole P, Hoover R, Friedell GH


This study is designed to estimate the incident risk of bladder cancer as it is associated with specific occupations. Data based on case reports of 461 persons with cancer of the lower urinary tract were compared to case reports of a control group series of 485 persons. The occupational categories for all persons in the test series are defined and adjusted for age and length of employment. Excessive risk patterns are found to exist in five specific occupation areas: 1) dye-stuffs: 2) rubber; 3) leather; 4) paint; and 5) organic chemicals. Data analyses showed that these categories accounted for 7.3/100,000 cases of urinary tract cancer in men of ages between 20-89 years of age and is considered to be significant. In addition, data provided insight into several occupations which had not been previously suspected as being hazardous. Simultaneous inquiry into the role of cigarette smoking as an aspect of occupational risk in cancer of the urinary tract indicated no correlation existed either directly or indirectly among clerical workers.
