Black/white differences in non-treatment of bladder cancer patients and implications for survival.
Am J Public Health 1989;79(6):772-5.

”Analysis of 20,764 White and 882 Black bladder cancer patients diagnosed during 1978-85 indicates that Black patients were more likely than White patients to go untreated following diagnosis after adjustment for age- and stage-at-diagnosis, sex, and tumor histology (OR=1.80, 95% CI= 1.33,2.43). Treatment status was found to be a significant predictor of five-year survival after adjustment (treated/untreated OR= 3.16, 95% CI= 2.08, 4.79). Results suggest that differences in initial therapy may contribute to the survival difference between Black and White bladder cancer patients.”

“This logistic regression model was also used to analyze our data by registry. The non-treatment odds ratio for Blacks versus Whites was 1.74 (95% CI=0.79, 3.82) in Atlanta, 3.10 (95% CI= 1.50, 6.41) in Connecticut, 1.38 (95% CI= 0,84, 2.26) in Metropolitan Detroit, 2.66 (95% CI= 0.29, 24.51) in New Mexico, and 1.60 (95% CI= 0.72, 3.56) in San Francisco-Oakland.”

“A more complete assessment is needed of Black/White differences in patterns and quality of bladder cancer treatment, their biologic, socioeconomic, and behavioral determinants, and their impact on survival.”
