Description

BACKGROUND. Blacks are less likely than whites to develop bladder cancer; although once diagnosed, blacks experience poorer survival. This study sought to examine multiple biological and behavioral factors and their influence on extent of disease. METHODS. A population-based cohort of black bladder cancer patients and a random sample of frequency-matched white bladder cancer patients, stratified by age, gender, and race were identified through cancer registry systems in metropolitan Atlanta, New Orleans, and the San Francisco/Oakland area. Patients were ages 20-79 years at bladder cancer diagnosis from 1985-1987, and had no previous cancer history. Medical records were reviewed at initial diagnosis. Of the patients selected for study, a total of 77% of patients was interviewed. Grade, stage, and other variables (including age, socioeconomic status, symptom duration, and smoking history) were recorded. Extent of disease was modeled in 497 patients with urothelial carcinoma using logistic regression. RESULTS. Extent of disease at diagnosis was significantly greater in Blacks than in Whites. Older age group, higher tumor grade, larger tumors, and presence of carcinoma in situ were related to greater extent of disease in blacks and in whites. Large disparities between blacks and whites were found for socioeconomic status and source of care. Blacks had greater symptom duration and higher grade. Black women were more likely to have invasive disease than white women; this difference was not seen among men. Blacks in unskilled occupational categories, perhaps reflecting socioeconomic factors, were at much higher risk for muscle invasion than whites. CONCLUSIONS. While specific relationships between variables were noted, an overall pattern defining black and white differences in stage did not emerge. Future studies should examine the basis upon which occupation and life style factors operate by using biochemical and molecular methods to study the genetic factors involved.
