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 are described here. METHODS: Five calls for data have yielded a total of 3,700,000 cases for the years 1985 through 1993, including 477,679 cases for 1988, and 608,593 cases for 1993, from hospital cancer registries across the U.S. RESULTS: The most recent call for data for 1993 comprised 52% of the estimated new cases of cancer in the U.S. The country was comprised of 6 regions, with the Mountain and Southeast regions having the highest regional reporting of new cases of cancer (69% and 55%, respectively) and the Northeast and Pacific regions having the lowest (47% each). Approximately 96% of patients received their treatment at the reporting hospital. The 4 most common carcinomas were breast (15.7%), lung (14.6%), prostate (14.2%), and colon (7.5%) and comprised the majority of new cases. Trends in patterns of care for breast carcinoma were analyzed for possible bias in the 1988 and 1993 periods. When hospitals reporting only in 1988 or in 1993 were compared with hospitals reporting at both time points, the only differences were small differences in ethnic participation. These differences were less than 1.5% in the proportion of African Americans reported in the different time periods. There were no significant differences in the downstaging of breast carcinoma, or the role of conservative surgery or adjuvant radiation therapy. CONCLUSIONS: The NCDB is a cancer management and outcomes data base for health care organizations that presently comprises 52% of the estimated new cases in the U.S. This will increase to 80% as the approved hospitals of the Commission on Cancer are required to report to the NCDB. Comparison of breast carcinoma findings at two time periods appeared similar regardless of hospital reporting set (i.e., set of hospitals reporting for one period versus both periods).
