Transitional-cell carcinoma is the dominant histological type of malignant tumors of the urinary bladder.
There is limited information on risk factors for non-transitional-cell carcinoma (NTCC) of the bladder.
We used data from 9 case-control studies on bladder cancer from 6 European countries to examine the association between NTCC, tobacco smoking and occupation.
Information on 146 cases diagnosed with NTCC were matched by age, gender and study center to 727 non-cancer population or hospital controls and also with 722 transitional-cell-bladder-cancer controls.
Lifetime smoking and occupational history were evaluated.
A statistically significant excess risk for NTCC was observed for current smoking [odds ratio (OR)=3.61,95% confidence interval (Cl) 2.08-6.28]. The risk increased with higher tobacco consumption (OR for highest tertile of pack-years=7.01,95% Cl 3.60-13.66).
The risks were higher for squamous-cell carcinomas than for other types of NTCC.
Among major occupational groups, a significant excess risk was seen for field-crop and vegetable-farm workers (OR=2.06,95% Cl 1.03-4.10).
These results indicate that NTCC of the bladder is associated with smoking and specific occupations.
The risk pattern seems to differ, in part, from that observed for transitional-cell carcinoma of the bladder.
