BACKGROUND: Previous Commission on Cancer Data from the National Cancer Data Base (NCDB) have examined time trends in stage of disease, treatment patterns, and survival for selected cancers. The most current (1993) data relating to patients with bladder carcinoma are described here. METHODS: Five calls for data have yielded a total of 3,700,000 cases for the years 1985 through 1993, including 447,679 cases for 1988 and 608,593 cases for 1993, from hospital cancer registries across the U.S. Data were received on 18,053 bladder carcinoma cases in 1988 and 22,606 cases in 1993. RESULTS: Interesting trends are 1) younger patients (49 years of age and younger) present with earlier stages of disease than do older patients; 2) women are slightly more likely to be diagnosed with later stages (II, III, and IV) of bladder carcinoma than men; 3) African Americans are less likely to be diagnosed with Stage 0 or Stage I disease than either Hispanic or non-Hispanic whites; and 4) National Cancer Institute designated centers treat more patients with advanced disease than do other types of hospitals. CONCLUSIONS: The NCDB data are important for analyzing what cancer treatments and outcomes are used and occurring in the country. The data suggest that African Americans are diagnosed at later stages of disease progression. The relative survival rates among African Americans are lower than among Hispanics or non-Hispanic whites. Also, the decreasing utility of adjuvant chemotherapy is being recognized.
